Abstract
The objectives for the development of rainfed/ drylandagriculture are: to enhance moisture retention capacity of thesoil and retain rainfall by using agronomic, biological andengineering measures in an integrated way, to improve soilfertility and turn " three -losing land" (soil- water- and fertilizerlosing land) into " three conserving land" (soil- water- andfertilizer conserving land). A good deal of information has beengenerated on various aspects of crop production under normalas well as aberrant weather conditions. These include thepractices related to cost effective management of crops andcropping systems, rain water management, soil fertility andnutrient management, conservation of natural resources andtheir efficient management and conclusions have been drawnfor direct use by the beneficiaries.
From the results discussed in this paper it can be concludedthat the productivity under rainfed production system can besustained on long run basis if the measures suggested hereare implemented: (i) For reducing soil erosion, improvingorganic status of soil and improving economy of energy whileenhancing productivity and profitability of soybean basedproduction system conservation tillage is the sustainablepractice.(ii)Use of organics and green manure holds the keyto enhanced productivity and resource use efficiency.(iii) formaintaining soil health the balanced and adequate use ofnutrients through INM is essential.(iv) Adoption of watershedapproach for conservation and utilization of land and waterresources. (v) Soil and water management practices thatensure soil drainage and safe disposal of runoff should bedemonstrated on massive scale and popularized as an integralpart of package of improved practices for soybean. (vi) Thein-situ conservation of rainwater, use of stored water in thesurface ponds and dug wells should for supplemental irrigationto increase productivity of soybean based production system.(vii) Alternate land use system like agro-forestry and agro-horti should be popularized in shallow and marginal lands forimparting higher economic return and sustainability to soybean

To feed a growing world population, we have no optionbut to intensify crop production. Farmers faceunprecedented constraints. In order to grow, agriculturemust learn to save. Sustainable intensification requiressmarter precision technologies for irrigation, and farmingpractices that use ecosystem approaches to conserveresources including water, soil, nutrients and energy.
In most developing countries, there is little slopefor expansion of arable land. Virtually no spare land isavailable in South Asia. Between 2015 and 2030,therefore, an estimated 80 percent of the required foodproduction increase will have to come fromintensification in the form of yield increase and highercropping intensities (FAO 2003). However, in India therate of growth in yield of the major food crops - rice,wheat and maize - are all declining. Annual growth inwheat yields slipped from about 5 percent a year in 1980to 2 percent in 2005; yield growth in rice and maize fellfrom more than 3 percent to around 1 percent in thesame period (FAO 2009). In Asia, the degradation ofsoils and the buildup of toxins in intensive paddysystems have raised concerns that the slowdown in yieldgrowth reflects a deteriorating crop-growingenvironment (Hazell 2008).

The declining quality of the land and waterresources available for crop production has majorimplications for the future. The United NationsEnvironment Programme (UNEP) has estimated thatunsustainable land use practices result in global netlosses of cropland productivity averaging 0.2 percent ayear (Nellemann et al. 2009). Resource degradationreduces the efficiency of inputs, such as fertilizer andirrigation thereby, affect the agriculture profitabilityadversely. In the coming years, intensification of cropproduction will be required increasingly in more marginalproduction areas with less reliable productionconditions, including lower soil quality, more limitedaccess to water, and less favourable climate. Decliningtotal factor productivity, soil degradation, fertility mining,resource exploitative practices and combination of harshclimate and fragile soils are the major concerns whichwill affect agriculture profitability in the future. Therefore,it is most important to conserve soil and water resourcesin such a way so that resource use efficiency can beenhanced and profitability from agriculture can beincreased.
Therefore, there is a need to adopt land and watermanagement practices which are economically feasible,ecologically sustainable and are farmer friendly. Manylocation specific soil and water conserving technologieshave been developed which can increase agricultureprofitability in a sustainable way. A brief account of thesetechnologies has been discussed here. To-day the majorconcerns for making agriculture profitable should be (i)Soil health Improvement (ii) Tapping untapped potentialof rainfed agriculture.
Soil Health Improvement
Soil health has been defined as: the capacity of soil tofunction as a living system. Healthy soils maintain adiverse community of soil organisms that help to controlplant disease, insect and weed pests, form beneficialsymbiotic associations with plant roots, recycle essentialplant nutrients, improve soil structure with positiverepercussions for soil water and nutrient holdingcapacity, and ultimately improve crop production (IPCC2007). A healthy soil does not pollute the environment;rather, it contributes to mitigating climate change bymaintaining or increasing its carbon content.
Soil contains one of the Earth's most diverseassemblages of living organisms, intimately linked viaa complex food web. It can be either sick or healthy,depending on how it is managed. Two crucialcharacteristics of a healthy soil are the rich diversity ofits biota and the high content of non-living soil organic
matter. If the organic matter is increased or maintainedat a satisfactory level for productive crop growth, it canbe reasonably assumed that a soil is healthy. Healthysoil is resilient to outbreaks of soil-borne pests.(Rosenzweig and Tubiello 2006)
The diversity of soil biota is greater in the tropicsthan in temperate zones (Burney et al. 2010), becausethe rate of agricultural intensification in the future willgenerally be greater in the tropics, agro-ecosystemsthere are under particular threat of soil degradation.Any losses of biodiversity and, ultimately, ecosystemfunctioning, will affect subsistence farmers in the tropicsmore than in other regions, because they rely to a largerextent on these processes and their services. The trendof declining soil fertility in India is depicted Fig.1.
Functional interactions of soil biota with organicand inorganic components, air and water determine asoil's potential to store and release nutrients and waterto plants, and to promote and sustain plant growth.Large reserves of stored nutrients are, in themselves,no guarantee of high soil fertility or high crop production.As plants take up most of their nutrients in a watersoluble form, nutrient transformation and cycling -through processes that may be biological, chemical orphysical in nature - are essential. The nutrients need tobe transported to plant roots through free-flowing water.Soil structure is, therefore, another key component of ahealthy soil because it determines a soil's water-holdingcapacity and rooting depth. The rooting depth may berestricted by physical constraints, such as a high watertable, bedrock or other impenetrable layers, as well asby chemical problems such as soil acidity, salinity,sodality or toxic substances.
A shortage of any one of the 15 nutrients requiredfor plant growth can limit crop yield. To achieve the higherproductivity needed to meet current and future fooddemand, it is imperative to ensure their availability in

soils and to apply a balanced amount of nutrients fromorganic sources and from mineral fertilizers, if required.The timely provision of micronutrients in "fortified"fertilizers is a potential source of enhanced crop nutritionwhere deficiencies occur. Nitrogen can also be addedto soil by integrating N-fixing legumes and trees intocropping systems. Because they have deep roots, treesand some soil-improving legumes have the capacity topump up from the subsoil nutrients that would otherwisenever reach crops. Crop nutrition can be enhanced byother biological associations - for example, betweencrop roots and soil mycorrhizae, which help to capturephosphorus in depleted soils. Where these ecosystemprocesses fail to supply sufficient nutrients for highyields, intensive production will depend on the judiciousand efficient application of mineral fertilizers.
A combination of ecosystem processes and wiseuse of mineral fertilizers forms the basis of a sustainablesoil health management system that has the capacityto produce higher yields while using fewer externalinputs.
Technological options
• Increasing soil organic matter in soils.(INM andOrganic farming)
• Balanced fertilization on the basis of soil testvalues
• Application of micro nutrients in deficient soils(Zn, Mo, B, Fe etc.)
• Biological nitrogen fixation to enrich soils (Useof Biofertilizers)
• Use of slow release N- Fertilizers in Ricecultivation
• Direct seeded rice and zero-tillage in rice- wheatcultivation
• Low till farming strategy for soybean cultivation
• Tree crop interaction
Tapping Untapped Potential of Rainfed Agriculture
An important avenue for achieving increased productiongoals is to enhance the productivity of vast areas underrainfed agriculture, which constitute nearly 60% of thenet cultivated area of the country (Abrol 2005). Theseare areas where the green revolution technologies made
limited or no impact. These are also areas where vastmajority of the poor live and whose livelihoods areintimately linked to our ability to impact agriculture inthese areas. Rainfed agriculture is practiced under awide range of soil and climatic conditions. Rainfallregimes and soil characteristics are the keydeterminants of rainfed cropping potential. Theunirrigated areas differ widely with respect to both. Theamount and distribution of seasonal rainfall differ widelyamong regions as well as from year to year. Three majorsoil groups are found extensively in the rainfed regions:red, black and submontane soil. Rainfall in red-soilareas ranges from 750 to 2000 mm per annum. Soildepth varies but most soils are shallow and have lowwater-retention capacity. In the absence of cost effectivemoisture retention and conservation technologies, thesoil suffers from rapid water run-off and erosion reducingthe productive capacity. Red soils have considerableagronomic potential but to achieve this potential thereis need to popularize effective soil moistureconservation practices. Precipitation (Sehgal et al.1993) in black soil areas ranges from 500 to 1500 mm.Compared to the red soils, the black soils are deeperand heavier and hold more water. However, they arehighly erodible and run-off can be as high as 40% ormore depending on rainfall volume and intensity andon the slope. Surface drainage is essential in mediumand high rainfall regions. Given appropriatetechnologies to cope up with constraints associated withthese soils' considerable management difficulties thereis ample scope to enhance productivity. When wet, blacksoil swells and becomes sticky, but shrinks rapidly whendry, leaving large clods and deep fissures and posingconsiderable difficulties in field preparation and timelyplanting operations. There is a large gap between actualand potential crop yields in these regions and there aresignificant opportunities for increasing production. Thereis considerable potential to enhance productivity ofrainfed areas. Realizing this potential essentially hingeson our ability to reverse the process of degradation -processes that will contribute to institutionalize waterconservation, reduced run-off and erosion. Thus,resource conservation issues represent an essentialprerequisite to achieve enhanced productivity. Giventhe wide variations in soil, climate and socio-economicsituations, it is obvious that these technologies have toevolve and spread considering local situations and in aparticipatory manner. In the past there has been littleR&D effort, which recognizes that resource conservationis a precondition to sustained productivity increase.Over the past two decades, the Government of Indiahas devoted considerable attention and resources inprogrammes of watershed development in rainfedareas. These included several externally aided projects.
119
The main focus in these programmes was to generatewater resource by run-off collection and reuse of waterby concentrating on various engineering structures (Kerr1996, Samra 2005). While, these efforts have benefittedin some ways, a more fundamental way to sustainedproductivity is to reduce run-off and soil erosion bytechnologies which improve in situ conservation ofrainwater by improving the capacity of the soil to absorband retain water and reduce erosion, i.e. to bring abouta reversal in the processes that are leading todegradation (Acharya et al. 1998).
Rainfed Agriculture: Key Issues
• Continued resources degradation and increasedweather related risks
• Stagnant productivity in major growing districts
• Loss of soil fertility
• Stagnant/ falling cropping intensity (despiteavailability of technologies to increase CI)
• Poor replicability of watershed approach
• Poor technology uptake by stakeholder
• Threat of climate change and the effects thatfollow
Measures for profitable and sustainable agriculture
The objectives for the development of rainfed/drylandagriculture are: to enhance moisture retention capacityof the soil and retain rainfall by using agronomic,biological and engineering measures in an integratedway, to improve soil fertility and turn " three -losing land"(soil- water- and fertilizer losing land) into " threeconserving land" (soil- water- and fertilizer conservingland); to change farming practices and make full use ofresources like light, heat, soil, fertilizer, water andimproved seeds to increase yield and agricultureproductivity in the dry land.
A good deal of information has been generatedon various aspects of crop production under normal aswell as aberrant weather conditions. These include thepractices related to cost effective management of cropsand cropping systems, rain water management, soilfertility and nutrient management, conservation ofnatural resources and their efficient management andconclusions have been drawn for direct use by thebeneficiaries. The useful information generated so far,however, needs to reach the cultivators, as well as those
engaged in extension activities in rainfed farming forits practical utilization. The spectrum of rainfed farmingmay be broadly divided into the following four segments:
• Soil conservation and rainwater management
• Development of improved crop productiontechnologies
• Development of superior verities and crops forrainfed agriculture
• Adoption of technology developed by theresearch system

Integrated nutrient management for enhancing soil andcrop productivity
Soybean - based cropping sequence is a major croppingsequence, which has proved itself as one of the mostremunerative crop sequence for Malwa region ofMadhya Pradesh under rainfed conditions. It requiresthe information on changes in soil fertility, nutrientremoval hydro physical properties in long run. Further,in view of escalation of fertilizer, alternate sources ofnutrition and economy in fertilizer have becomeessential. Keeping above referred facts in view; anexperiment was started in the year of 1992. Results ofthis long term study have been found encouraging.

Studies on permanent manorial trails at Indore(1993-2012) exhibited that the conjoint use of FYMalong with chemical fertilizers helps in increasingsoybean yields on sustainable basis (Table 1).Application of FYM has been found to increase wateruse efficiency, moisture availability to rainfed soybean-safflower sequences and recovery of N, P, K and S fromblack clay soils. The productivity of soybean can beincreased with application of FYM @ 6 t/ha + 50% ofthe recommended dose of N and P. The highestsustainability index of 0.50 was obtained in thistreatment as against 0.24 of recommended dose ofchemical fertilizers (Table 2).
The highest safflower seed yield of 1408 kgha-1
was observed due to the treatment FYM 6 t + N20P13which was statistically superior to the rest of thetreatments. Thus, a combination of 6 t FYM, 20 kg Nand 13 kg P is optimum for realizing higher yield ofsafflower. Decline in levels of fertilizer N and P down to60 kg N and 35 kg P ha-1 resulted in gradual reductionin seed yield of safflower (Table 2). Application of FYMat the rate, of 6 t ha-1 along with reduced level of fertilizer(FYM + N20P13) resulted 35% additional seed yield ofsafflower as compared to the treatment having RDF. Cropresidues application as surface mulch at the rate of 5 tha-1 alongwith reduced level of fertilizer N and P(Residues 5 t + N20P13) enhanced the seed yield in therange of about 14.6 %. The highest sustainable yieldindex (SYI) of 0.41 was estimated due to conjunctiveuse of FYM at the rate of 6 t ha-1 along with reducedlevels of fertilizer N and P at the rate of 20 and 13 kg
ha-1 (Table 2). Chemical fertilizer application 60 kg Nand 35 kg P ha-1 gave sustainable yield index of 0.30which, emphasized that integrated application of nutrientenhances crop productivity of safflower on sustainablebasis when applied in Vertisols under rainfed conditions.
The highest gram grain yield of 1372 kg ha-1wasrecorded due to half of the recommended dose of Nand P + 6 t ha-1 of FYM (T6: FYM 6t ha-1 + T2) followedby 1258 kg ha-1 seed yield due to the treatment T7(Residues 5 t ha-1 + T2) and 1211 kg ha-1 in T5 (N60 P35),all these Treatments were statistically at par with each

other. The lowest seed yield (566 kg ha-1) was obtainedin case of T1 (control) i.e., N0 P0. All these Treatmentsgave significantly higher yield than control and othertreatments. The trend of straw yield commensurate withthe seed yield. The maximum Net return and B: C ratiowas obtained through treatment T6 i.e., FYM 6 t/ha + T2and lowest in case of control (Table 3).
Soil quality assessment in permanent manorial trial
Effect on soil physical properties
To evaluate the long term effect of treatments on soilaggregation, bulk density and surface soil porosity,
surface samples were analyzed (Table 4). The data thatthe maximum mean weight diameter (MWD) wasobtained in the treatment T6 (FYM + N20 P13) i.e. 1.80and minimum in case of control i.e. 0.49. In general theFYM and crop residue added treatments gave higherMWD in comparison to chemical fertilizer addedtreatment (Fig 2). The FYM applied treatments i.e. FYM+ N20 P13 gave 72.7% higher MWD than controltreatment (N0P0). Addition of organic along with chemicalfertilizer and alone reduced the bulk density (Table 4and Fig 3). The lowest bulk density of 1.17 Mg m-3 wasobtained in case of FYM + N20 P13 treatment followedby treatments, T7, T8, T9. Due to increased MWD andreduced bulk density the porosity of soil has alsoincreased in organic amendments treated plots. Theporosity ranged from 47.17% to 55.85% in differenttreatments and was highest in the treatment T6 (FYM +N20 P13) and lowest in case of control (Fig 4). The dataon infiltration rate was measured using double ringinfiltrometer method (Fig. 5). Three is a markeddifference in the initial infiltration rate of differenttreatments this difference was persisted till 9 hours ofelapse time, but the magnitude of difference wasreduced with time. This shows that there is a markeddifference in the initial infiltration rate due to differenttreatments but there may not be a difference in the finalIR. Results also revealed that organically amendedtreatments have higher cumulative infiltration rate thanthat of other treatments. The changes in soil propertiesdue to different treatments are the cumulative effect of18 previous seasons as the site of each treatment wasfixed.
Addition of organics and RDF has helped to buildup soil fertility but lower doses of N and P as compared

to RDF has depleted the soil fertility in terms of OC, N,P, K and S content. The perusal of the data reveledthat OC balance was found negative in the treatmentT1, T2, T3, T4 and T5. While there was a positive balanceis there in the treatments which comprised of additionof organics viz. T6, T7, T8 and T9. In case of nitrogenthere was a negative balance in T1 (Control) T2, T8 andT9 treatments rest of the treatments have positivebalance. The P and K balance was found positive in allthe treatments except T1 control, where P balance wasnegative. S balance was found negative in all thetreatments (Fig. 6 through 9).
Recommendation
Based on long-term study, half of the RDF (N20 P13) foreach of soybean and subsequent rabi crops inconjunction with FYM 6t/ha for soybean isrecommended for achieving highest sustainableproductivity of rainfed soybean based cropping systemin Vertisols.
Advantages
• Provides higher sustainability to crop productivity(0.50) as compared to other treatmentcombinations
• Enhances crop yield by 10% as compared to RDF
• Enhances organic carbon content of soil (76%higher than control)
• The per cent increase in N, P, K and S was 76%,39.31%, 35.7%, 55.8% and 77%, respectivelyover control. These changes are the cumulativeeffect of 13 years

of recommendation fertilizer practices on yield anduptake of nutrients in Soybean and wheat crops. Thehighest grain yield (1561kgha-1), straw yield (3051kgha-1) content and uptake of nutrients in soybean wasobtained in 100% recommended NPK fertilizers alongwith 15t FYM ha-1 was applied, while lowest wasrecorded in control. In wheat highest grain yield (5878kg ha-1), straw yield (8066 kg ha-1) content and uptakeof nutrients was also obtained in 100% recommendedNPK fertilizers along with 15t FYM ha-1 was applied,while lowest was recorded in control. The maximum B:Cratio (1.89) was recorded in 150% NPK treatment insoybean crop while in case of wheat the maximum B:Cratio (4.79) was recorded in 100% NPK+FYM treatment(Table 5).
Nitrogen management in rice - wheat system
Low N use efficiency in rice - wheat system, especiallyin rice is a major concerned, recommendation has beenevolved for application of FYM along with urea supergranules/ prilled urea deep placement for rice crop. Datapresented in Table 6 revealed that significantly higheryield of paddy was recorded when N was appliedthrough Urea Super granule (USG) along with FYM @5tha-1. All the amendments in combination with USGgave higher grain yield of paddy in comparison to prilledurea combinations. The grain yield of rabi crops wasalso significantly superior in amendment treated plotsirrespective of forms of urea used. Application of organicamendments improved the soil physical environment,which has favourable effect on the grain yield of bothpaddy and subsequent rabi crops (Fig10).
Low till farming strategy for improving crop productivityand soil quality in long run
With the objective of exploring potential of conservationtillage in rainfed soybean based production system forenhancing productivity and soil quality, a f ieldexperiment was initiated in the year 1999 at Indore forevolving low till farming strategies for rainfed productionsystem. On the basis of sustainability index it isrecommended that the study emphasized for conjointuse of organics with reduced level of tillage andchemicals which are not only cost effective but alsoenhance the productivity of soybean and build up soilhealth in the long run. Under rainfed conditions soybeanshould be grown with the addition of organics such ascompost, straw as a mulch and addition of toppling ofgliricidia. With the help of these additives low till farmingstrategy is highly recommended with hand weeding as
125
the application of herbicide was not found effective andlow sustainability index was obtained in the treatmentsinvolving herbicide application.
The major recommendation emerge from theexperiment is that low till farming strategy (minimumtillage + use of organics i.e. Compost @ 5t/ha, Gliricidialeaves @ 2t/ha) is recommended for enhancingproductivity and soil quality in long run under rainfedconditions. Low till farming strategy can be adopted inplace of intensive cultivation which includes low tillage+ use of organics like compost, straw and gliricidiatoppling. The SI > 0.50 revealed that this is one of themost promising technologies for rainfed soybean inVertisols.
The long-term data of soybean yield as influencedby different treatments has been depicted in Table 7,from the data it is evident that the treatment T3- (lowtillage + 4t /ha straw + HW) which was found statisticallyinferior to the treatment T1 and T2 in the initial two yearswas found at par with these treatments after two yearsand there was a gradual but steady increase in this lowtill system and notably after a span of 2 years the yieldwas at par with T1 and T2, while this treatment was foundenergy conserving (Fig 11) and economically morefeasible. Root study revealed that with low tillage andaddition of organics higher root length can be achievedas compred to conventional tillage and intensive tillagewith RDF in Vertisols of dry land conditions.
Fig 11. Energy balance under different treatments
Advantages of low till farming
• The sustainability index (SI) calculated for thelow farming strategy treatment revealed that thisis one of the most promising technologies forrainfed soybean in Vertisols as the SustainabilityIndex is > 0.50.
• Improves soil quality in terms of increased levelsof available OC (0.77%), N (278 kg/ha), P2O5(58.80 kg/ha), K2O (710 kg/ha) and S (12.11 kg/ha) as compared to control in which case thevalues of available OC (0.52%), N (207 kg/ha),P2O5 (36.0 kg/ha), K2O (692 kg/ha) and S (7.19kg/ha).
• Over all results suggested that by the use oforganics the tillage intensity can be reducedwhich will help in increasing soil quality andreducing energy consumption without sacrificingthe crop yields.
Reduced tillage option for Rice-wheat system
In a long-term study conducted (1991 to 2000) underrice wheat cropping system in Vertisols (TypicHaplusters) at Jabalpur, MP, India it was reported thatpuddling during rice deteriorates the soil physicalenvironment for subsequent wheat crop as comparedto under direct seeded plots. It was concluded that inVertisols paddy should be grown as direct seeded crop,which provides better physical environment forsubsequent wheat crop. Significantly higher yield ofwheat was recorded in direct seeded paddy plots as

compared to transplanted plots, and the totalproductivity of the system was higher under reducedtillage conditions i.e. Direct seeded paddy followed byzero till wheat (Fig 12 and 13).
The mean yield of transplanted rice (TP) washigher than the yield of direct seeded rice (DS) (Table 8& Fig 12). Out of ten years the grain yield of TP ricewas significantly higher in six years than the DS rice,while in other years the yield levels were statistically atpar except during 1992 where the DS paddy gavesignificantly higher yield than that of transplanted paddy.A comparison of method of rice cultivation on root growthshowed that total root length upto 45 cm depth wassignificantly higher in Ds rice as compared to that in TPrice Fig 14.The soil organic carbon content was
significantly higher under Ds rice than the TP rice (Fig15). Lal (1986) also reported 2.2 and 1.7 per centorganic carbon in unpuddled and puddled plots,respectively.
On black clay Vertisols, moisture content profile(Fig 16) at harvest were similar on puddled andunpuddled soils. But drying and the rate of drying weregreater an nonpuddled soils. Cultivation of puddledpaddy produces cloddy seedbed, resulting in poor seedsoil contact, rapid drying of surface soil and reducesgermination. Having to wait for a puddled soil to arriveat the optimum moisture content for tillage has anotherdisadvantage. A longer 'turnaround' time resulted in lowcrop yields. Results of regional experiments showedthat delay in wheat planting results in decrease in yieldpotential in the range of 1 to 1.5 percent loss/ha/daywhen planting occurs beyond last week of November(Tomar and Verma 1985). Late planting not only resultsin lower yield but also reduces the efficiency of appliedinputs. Fig 17 shows the wheat yield reduction patternwhen it s planted beyond November (Tomar and Verma1985).
The long term results of rice-wheat croppingsystem in Vertisols (Typic Haplusterts ) at JNKVV,Jabalpur, MP (AICRP on tillage requirement of majorIndian soils), revealed that zero tillage as atechnological option for timely establishment of wheat.In this technique, direct drilling of wheat using PantnagarZero till fertilizer seed drill can be done without anytillage operations immediately after harvest of paddyon residual moisture. In rice -wheat system, paddyfollowed by no till wheat resulted in significantlyincreased productivity of rice wheat system as comparedto the productivity of paddy followed by shallow till ordeep till wheat (Fig 12&13). Zero tillage has yieldadvantage particularly in early sown crop i.e. Novemberplanted wheat (Table 9). No till system of wheat andreduced tillage in paddy (avoiding puddling and direct

seeding of paddy) helped to reduce the turnaround timeand get the wheat planted closure to the optimum date.This system offers the advantages of timely wheatsowing, favouring crop productivity, saving energy (Fig18) and improving water and nutrient use efficiency (Fig19). This system not only increases productivity of thesystem but also reduces the cost of cultivation, fuel cost,wear and tear of tractors and increases input useefficiency. The farmers of rice wheat sequence areresource poor and the savings on tillage operations canbe used to buy other inputs like weedicides, fertilizer,irrigation which will further enhance productivity. Thetwin advantage of enhancement of productivity and its
profitability under zero till system, will go a long way inenhancing the sustainability of rice wheat system.
Data presented in Table 9 further indicated thatafter six years of experimentation there is decrease inyield of wheat under zero till plots. Poor yield of wheatrecorded during 1997-98 was due to continuous heavyrains received in the month of November and Decembermonths.
Recycling of crop residue
Field experiment was conducted in Vertisols at Jabalpurby incorporating of rice and wheat crop residue both insitu or as compost, increased the soil organic carboncontent and improved soil health (Fig. 22), whileimproving the productivity of the rice-wheat system. Thereturn of carbon to soil and yield of crops was maximum,when crop residue was added along with fertilizer N @120 kg N ha-1.

40-50% of total rain water is lost as runoff from maizeand soybean fields (Bhargava et al. 1976; Tomar et al.1985). The success of water harvesting depends notonly on the collection of runoff water but also on theefficient utilization of this harvested water for theagricultural crops.
The runoff under 1.2% slope was 146 mm (56per cent) from ridge and 121.7 mm (46.9%) from flatplots with total rainfall of 259 mm (Table 10).
The harvested water was recycled for irrigationof different crops to avoid the adverse effect of dry spellsunder rainfed conditions. The differential crop responseof one or two irrigation from harvested water wasstudied. The results (Table-11) indicate the all the cropsresponded well to irrigation treatment.
Harvesting of runoff at micro level, its storageand recycling for life saving irrigation during long dryspells improving the productivity of a rainy season crop.

This practice if adopted on large scale, is potentiallycapable of addressing twin problems of water stagnationduring kharif and moisture stress during rabi. The highrunoff potential at Indore, Jabalpur, Rewa and otherregions (Verma 1982) with similar climatic conditionspermits two good irrigations. Minimization of surfacewater evaporation and seepage losses of water fromthe reservoirs can further improve the irrigation potentialof the harvested water. Use of monomolecular layer oforganic compounds such as DDAC,), hexadecanol,Octadecanol has been found to minimize evaporationfrom soil and reservoirs. An appropriate landmanagement system combined with water harvestingand recycling system seem to offer vast prospects ofimproving productivity of Vertisols even under rainfedconditions. If harvested rainwater is used in theproduction of high value crops like vegetables,floriculture, fruit trees, it will bring higher monitory returnsfrom the rainfed areas.
Soil and Water Conservation Practices
Under increasing population pressure for moreagricultural production, extensive cultivation by puttingmore area under cultivation cannot be pursued any morefor ecological considerations. The onus for moreagriculture production, therefore, falls on the judicioususe of the land and water is a must for sustainable cropproduction, especially under rainfed farming. Major soilsof rainfed areas of Madhya Pradesh, where soybean isgrown, are black soils (Vertisols and associated soils).Despite of the fact that the black soils are potentiallyproductive but there are certain soils related constraints,which deter the farmers for realizing the potential
productivity of upland kharif crops. The solution to theproblems/constraints lies in such water and landmanagement practices, which encourage surfacedrainage and recharge of the soil profile with rain waterwithout accelerating soil erosion, In the work underreport, the performance of soybean crop grown as soleand intercrop on Vertisols during rainy season wasevaluated under varying drainage conditions so as tointroduce most appropriate soil management practicesfor growing these crops in the Vertisols of high rainfallregions of central India. Different land configurationsand management practices developed are discussedbelow.
Ridge and Furrow System
Ridge and furrow system envisages planting of uplandrainy season crops on ridges laid out on such soilshaving slopes less than 1%. Furrows serves as aneffective means of surface drainage and carry excesswater into cut-off drains dug across the slope. Thesystem is highly effective in medium and high rainfallareas (rainfall ranging from 700 to 1200 mm). Datapresented in Table 12 reveals that considerable higherproduction of soybean can be obtained when plantedon ridges.
Graded furrows
Graded furrows of 0.20 to 0.30 % slope serve the meansfor carrying runoff water to drainage channel safely andlead to enhanced productivity of upland rainy seasoncrops specially in areas which receive moderate rainfall(> 1000 mm). Spacing between furrows may vary from8 to 10 m depending upon slope and rainfallcharacteristics.Table 11. Effect of use of runoff water on the grain yield

Broad bed and Furrow System
In this system beds and furrows are created on a gradeof 0.5% slope. This system consists of a series of broadbeds and furrows accommodated 90-150 cm wideparallel running strips. This system permits safe disposalof runoff, tends to conserve soil and water in-situ,reduces soil and nutrient losses and enhances cropproductivity and water use efficiency. This systemreduces runoff, soil loss, Nitrogen and Phosphorus lossby 13.5,30.1, 16.1 and 13.5% respectively over flat bedson conventional system of cultivation and enhancedsoybean yield, water use and water use efficiency by20.6%, 4.0% and 7.9 %, respectively (Gupta andSharma 1990). Study conducted at ICRISAT revealedthat total runoff and peak runoff rates were lower onBBF landform compared to those on flat landform, Soilerosion was lower in BBF as compared to that in flatlandform treatment. Integrated nutrient managementfollowed in improved system (sowing on BBF + Gliricidiaon bunds) resulted in improved balanced N Budget forsoybean + Chickpea sequential and soybean/pigeonpea intercropping system. Gliricidia topplingprovided 25 kg N/ha/year without adversely affectingcrop yields of the nearby rows. The yields obtained inthese sequences were much higher than the soybeanaverage yield of Madhya Pradesh (<1t/ha).
Raised and Sunken bed System
To improve the productivity of rainfed Vertisols in sucharea, there is a need to provide to the resource poorfarmers such a system, which will provide adequatemeans of surface drainage at a cheaper cost than sub-surface drainage and will also assure adequate rootzone moisture recharge for Kharif (Rainy season) crops.Jabalpur centre of the AICRP on Soil PhysicalConstraints and their amelioration for sustainable cropproduction has conducted field experiments over morethan 16 years to develop and validate Raised-SunkenBed Technology. This technology provides: an adequatedrainage during heavy rains, favourable moistureregime during dry spell in Kharif season to upland crops,sufficient ponding of water for paddy and channelizesthe excess runoff water safely to a farm pond forrecycling to provide supplemental irrigation to rainy andpost rainy season crops. The technology has beendemonstrated successfully at the farmers fields inMadhya Pradesh and also found beneficial by theParbhani (Maharashtra) centre of the project. InMaharashtra approximately 0.53 m ha land experiencestemporary water logging during rainy season.
Based on long-term trials at Jabalpur (MP)involving various crops the recommended raised-

sunken bed system consists of 6 to 9 m wide and 30 to35 m high raised bed along which runs the sunken bedof 6m width. The sunken beds are connected forexample with the pipes to maintain water level at adesired height viz. 15 to 20 cm in all the sunken beds.The excess water is safely carried away and collectedin a farm pond for recycling to provide supplementalirrigation to rainy season and post rainy season crops.
Raised-Sunken Bed System can be created bymechanically shifting surface soil from a strip with thehelp of a suitable device for example a motor graderwas used in Jabalpur, and placed on the adjoiningparallel running strip. For operational convenience soilfrom half width of the area to be created into sunkenbed is put on the right and from another half on the leftside. The strip from where the soil is shifted getsconverted into a sunken bed and the strip where on theshifted soil is put gets converted into a raised bed. Theraised bed may also be created using dug out farm pondsoil. The beds are leveled and soil allowed to settlebefore raising a crop. The land shaping operation ispreferably done in summer before onset of the rains. In
the first year, to make up the fertility of the exposed subsurface soil in the sunken bed, addition of extra FYM,ZnSO4 and nutrients etc. is recommended in Kharif.Raised bed is used for upland crops and sunken bedfor rice.
Seed yield of soybean (cultivars JS 2 or JS 75-46 or JS 335) observed over a period of 16 years wasin general more than two times under improved systemof Raised-Sunken Bed as compared to farmers practiceof flat bed sowing (Table 13).
Raised-Sunken Bed system has also been foundsuccessful for intercropping upland crops on raised bed.Two rows of soybean or blackgram followed by one rowof pigeonpea (medium duration) produced 3, 12 & 4times higher yield for soybean sole, pigeonpea sole andsoybean + pigeonpea intercrop (Table 14) underimproved system compared to farmers practice. It wasobserved that in most of the years pigeonpea andblackgram could not survive in flat bed (farmers practice)but performed satisfactorily under the improved system.The total productivity under improved system of soybean

+ pigeonpea cropping was more than 3.3 t/ha whichfrom a view point of yield under rainfed condition inVertisols of the region was a good yield. The mainadvantage of the intercropping was that even if the rainsceased earlier the pigeonpea survived on residualmoisture left over in the profile. The intercropping resultssuggest that by incorporating it in Raised-Sunken BedTechnology crop productivity can be increased in highrainfall areas of Vertisols regions.
Performance of post rainy season crops grownon raised bed and sunken bed was evaluated againstfarmer's practice of flat bed sowing. As compared tofarmers practice i.e. flat bed sowing under improvedsystem the yield of each test crop was nearly two timesmore (Table 15). This could be attributed to morefavorable moisture regime in the seed zone underimproved system at the harvest of rainy season cropresulting in better establishment and improved stand ofpost rainy season crop.
Benefit-cost ratio based on the prices prevailingin the year 1997 foe various operations and yields haverevealed that the Raised-Sunken Bed System waseconomically viable under all the major croppingsystems of the region (Table 16). The benefit-cost ratioshowed that the land shaping cost could be recoveredwithin 1 to 2 year. Economics also revealed that in case
of failure of post rainy season crops or even paddyduring Kharif (due to scanty rains as was the case in1979 and 1981) improved system gave higher returnscompared to the farmers practice. Highest benefit-costratio was observed in soybean-pigeonpea intercroppingon raised bed and paddy-chickpea in sunken bed.
Soil conservation techniques
Many soil conservation techniques are found suitablefor reducing erosion and nutrient losses and helps inmaintaining soil fertility and enhancing soil productivity.Runoff induced soil erosion is accompanied by heavylosses of essential nutrients particularly nitrogen. Theselosses can be minimized through employment ofappropriate land treatment and water disposal systems.In past, contour bunding has been used as a soilconservation measure in black soil region but thesehave been reported to adversely affect the crop yield(Kampen, 1974) and not at all suited to moderate tohigh rainfall areas. Biological measures are generallyused as preventive measures. Some of the cost effectiveand promising erosion control mechanical measuresare; Gabion structures, Graded bunds, Conservationditches, Bench terracing and Water diversion bunds andbiological measures include planting of Cover crops,mulching with crop residue, and vegetative barriers etc.

losses. Later on, upon decomposition, it adds nutrientsfor the benefit of crops and enhance water useefficiency. Crop residues like sorghum cob husk, maizestalks, safflower straw, soybean straw, weed biomassor any other locally available crop residues, which havevery little or no fodder values may be utilized formulching purposes. Usually they can be applied at therate of 5 to 8 t/ha. After emergence and establishmentof crops, straw or crop residues may be spread inbetween crop rows. Straw mulching besides reducingerosion and enhancing infiltration, increases water useefficiency of crops to a considerable extent (Sharma etal., 1985a, Sharma et al. 1985b). Experimental results

Mulching with Crop Residues
The potential value of crop residues as surface mulchfor soil and water conservation is well established.Moderate rates of residue application may be effectivein enhancing the infiltration and reducing runoff.However, larger amounts may be required tosignificantly cut down evaporative losses of profile-stored moisture. Surface residues mulch have theirgreater values for water conservation when soils arewet. The immediate advantage of incorporation of cropresidues in soil is to enhance infiltration and retard runoff

(Table 17) indicate that during post-rainy season, shortduration crops of chickpea and linseed respondedremarkably well as compared with wheat and safflowerto 6 t /ha of sorghum cob husk used as surface mulchduring post rainy period. After harvesting of crops,residues, which are used as surface mulch, may beincorporated in soil, which upon decomposition in soilwould help in improving soil physicochemical propertiesand fertility of soil.
Vegetative Barriers/Hedges
Vegetative barriers/ hedges have been found useful inreducing the rain water runoff water and conserving soiland plant nutrients. These are also helpful in stabilizingthe earthen bunds, particularly in black soil regionswhere massonary structures have limited utility due toswell shrink nature of these soils. For this purposes anumber of grass species have been identified. Grassessuch as vetiver, Cymbopogon martinii have proved tobe useful (Table 18). Vegetative hedges are establishedat 0.5 to 0.75 m vertical interval. Two rows planted 30cm apart make a good hedge, which should be regularlycut to maintain 30 cm height.
Agronomic Measures
Land use system should be based on land capabilityclasses as far as possible so as to ensure efficient useof land and profile stored water. Agronomic practiceswhich encourage conservation of soil, rain water andplant nutrients and enhance use efficiency of theseresources are soil mulching, plastic mulching, contourfarming, strip cropping, integrated nutrient managementpractices and minimum tillage practices etc.
Soil Mulching / Shallow Interculture / Shallow Tillage
Soil mulch created in-situ tends to reduce evaporationas it minimises and delays development of shrinkagecracks and besides providing a diffusion barrier (Sharmaet. al., 2005 ). Soil mulch may be created with the helpof a suitable implement (hand-hoe, blade harrow etc.)in between crop rows as and when required. Animaldrawn small blade harrow (blade width of 15 to 30 cm )can be conveniently operated in between crop rows tocreate soil mulch in-situ during early growth period ofrainy season crops like soybean, maize, sorghum,cotton and pigeonpea etc. It can create 2 to 3 cm loosesoil and removes growing weeds. During post-rainyseason period, soil mulch delays the appearance of
shrinkage cracks. Effectiveness of soil mulching varieswith the crop type. On an average 6 to 25 per centincrease in water use efficiency of post rainy seasoncrops can be realised due to soil mulching (Table 17).
Deep Tillage Practices
Deep tillage prior to onset of rainy season is practicedmainly with a view to increase infiltration and therebyreduce runoff, soil erosion and weed population. Offseason deep tillage, particularly in subnormal rainfallyears, has been found useful in conserving the soil andwater resources and enhancing the crop yieldssubstantially.
Plastic Mulching
Plastic mulches although conserve soil profile storedmoisture leading to sustainable increase in water useefficiency and crop yields but they are not cost effectivefor large scale adoption (Sharma 1976). They can beof immense use for soil solarisation (meant forminimising the incidence of weeds and soil bornediseases), or for growing cash crops.
Contour Farming
In contour farming, tillage operations are done alongthe contour lines as far as possible. It creates numerousridges and furrows, which retain a good volume ofrainwater after each wet spell. This water eventuallyinfiltrates into soil. There is corresponding reduction inrunoff volumes and therefore in erosion of soil and plantnutrients. Experiments conducted at Octacamond (India)have shown that by adopting contour farming for potato,cultivated on 25% slope, runoff was reduced from 52 to29 mm and soil loss from 39 to 15 t/ha when rainfallreceived was moderate.
Strip Cropping
Strip cropping is the method of growing strips of covercrops in the same field along contours for controllingwater erosion. Broad leaf pulses and grasses usuallyprovide effective strips for reducing runoff and erosion.

soil from erosion to some extent. For erosion control ingently sloping areas, mixed cropping or intercroppingmay be practiced in order to cover the maximum surfacefor a longer period. Minimum tillage during post rainyperiod reduces evaporation from soil, improvesestablishment of post rainy season crop (Sharma1990a).
Seed Replacement
This refers to the use of drought enduring and draughtresistant seeds. To use drought enduring varieties is themost cost effective yield increasing technology. Atpresent most dry areas have their own varieties withgood drought resistance. However, most varieties haveexperienced degradation in their performance and thebreeding of new varieties is still lagging behind. It is anurgent need to develop drought resistant varieties andaccelerate the purification and rejuvenation process inorder to improve yield levels in rainfed area.
Land Use According to its Capability
After employing appropriate conservation measures, itis essential to make efficient use of land resource forits protection and preservation and prevent furtherdegradation. Land use should be planned based on itscapability classes as any abuse of land at any point oftime would be the beginning of land deterioration at avery faster rate.
Alternate Land Use Systems
Increased use efficiency of marginal lands can beensured by planting them to suitable systems. A numberof options of alternate land use systems have beenidentified for different locations (Singh 1988). Differenthigh value crops like medicinal plant, spices etc, trees,Pastures and Livestock have got their own importanceto find place for making alternate land uses underrainfed situations. The biodiversity of native vegetationin drylands has been comprehensively reviewed bySuresh Kumar (1999). Trees, shrubs and native pasturesare the most important natural vegetation sources.Several multipurpose tree species yielding timber,fodder and fuel wood grow in SAT region on field bundsand scattered in the fields (park land system). This is atraditional agroforestry system. Recent research hasfocused upon systematic integration of trees, crops andgrasses through agrisilviculture, horticulture andsilvipasture. Nitrogen fixing trees (NFTs) have a special
role in rainfed farming systems from the point of view ofnutrient cycling. A number of economically importantshrubs yielding fruits, medicines and aromatic productsoccur in SAT region with high promise for value additionand export. The general recommendations for alternateland use systems based on annual rainfall and landcapability are outlined (Table 19).
Agri-horticulture
In medium soil areas (LCC II to IV) receiving annualrainfall of more than 750 mm, agri- horticultural systemsconsisting of a fruit trees intercropped with annual arablecrop is recommended. Ber, Custard apple, Aonla, andpomegranate are some of the species suitable fordrylands for both for pure plantations and mixed withcrops. Cluster bean, cow pea, horse gram, and othergrain legume have been found useful in this context inthe dry tracts of Andhra Pradesh, Maharashtra andKaarnataka. Results of a long term experimentconducted at AICRPDA, Indore, as an example of theadvantages of this system have been presented in Table20. The study comprised twelve treatment combinationswhich include three fruit tree components viz. Ber, Aonlaand Drumstick and four crop combinations i.e. solesoybean, sole pigeonpea, sole cowpea and intercropof soybean + pigeonpea (4:2). Results revealed thathighest SEY (Soybean Equivalent yield) and monetaryreturns were obtained through drumstick based agro-horti system. The SEY of 2388 kg/ha with monetaryreturn of Rs. 19859 per hectare was obtained from thetreatments T6 (Drum stick-Sole Pigeonpea). Resultsreveled tremendous scope of alternate land use ofcombining fruit trees and prevalent crops of Soybean,Pigeon pea and their intercrop combination. Lower yieldof cowpea was due to heavy rains during reproductivephase.
Studies on tree crop interaction involving variouscombinations of soybean crop and tree species revealedsynergistic effect on tree as well as crop component interms of crop yield and tree volume production (Table21). Though in Malwa plateau most of the soils areclassed as I to III, however, there could be certainshallow and marginal lands along with the hilly terrainunsuitable for arable cropping. For those lands a viableand remunerative alternative system has to be evolvedso that the socio economic conditions of the SAT farmerscould be improved. Studies conducted at AICRPDA,Indore reveled that the intercropping system of soybeanand pigeonpea 4:2 row ratio, when planted in betweenrows of fruit trees of Ber, Drumstick, Aonla, found moreremunerative in terms of soybean equivalent yield ascompared to sole soybean or cowpea (Table 20).

Intercropping
Intercropping of soybean and pigeonpea in the Shallow,medium and deep soils instead of sole crop isrecommended as it is found more sustainable and gavehigher B : C ratio therefore, recommended in place ofsole soybean under all the three soil depths. Incase ofintercropping the sustainability index ranged from 0.65to 0.83 while in case of sole soybean it ranged from0.37 to 0.50 only Table22. The potential croppingsystems for rainfed area of MP are presented in Table23.
Farming System Approach
This refers to reform of farming system according tolocal conditions to readjust crop structure and improveresource use efficiency productivity and income.Inclusion of multi enterprises like dairy, poultry fishcultivation, floriculture, mushroom cultivation, growingof medicinal crops are the key options for increasingfarmers income and should get priority for efficient modeldevelopment as per local conditions with sustainableproduction system specially for small and marginalfarmers of the region.

Conclusions
From the foregoing results discussed above it can beconcluded that the productivity under rainfed productionsystem can be sustained on long run basis if themeasures suggested below are implemented:
• For reducing soil erosion, improving organicstatus of soil and improving economy of energywhile enhancing productivity and profitability ofsoybean based production system conservationtillage is the sustainable practice.
• Use of organics and green manure holds the keyto enhanced productivity and resource useefficiency.
• Balanced and adequate use of nutrients throughINM.
• Adoption of watershed approach for conservationand utilization of land and water resources.
• Soil and water management practices that ensuresoil drainage and safe disposal of runoff shouldbe demonstrated on massive scale andpopularized as an integral part of package ofimproved practices for soybean.
• The in-situ conservation of rainwater, use ofstored water in the surface ponds and dug wellsshould for supplemental irrigation to increaseproductivity of soybean based production system.
• Alternate land use system like agro-forestry andagro-horti should be popularized in shallow andmarginal lands for imparting higher economicreturn and sustainability to soybean basedproduction system.
• Farming system approach and its evaluation fordifferent regions to develop most sustainablemodel for each region.
The overall strategy calls for rational use of avail-able technologies for soil and water management formaximizing productivity of soil- water and crop withoutdetriment to environment holds the key for maximizingthe agriculture profitability. To develop rainfed agricul-ture is a major strategic policy for sustainable agricul-ture development in India and also a major measure foragriculture development in 21st century. Let us join thehands to make our due contribution to development ofrainfed agriculture.

Abstract
Diagnostic ultrasonography is an ultrasound-based diagnosticimaging technique used for visualizing subcutaneous bodystructures including tendons, muscles, joints, vessels andinternal organs for possible pathology or lesions. Ultrasoundapplies to all sound waves with a frequency above the audiblerange of human hearing, about 20,000 Hz. The frequenciesused in diagnostic ultrasound are typically between 1 and 10MHz. In cattles, with acute abdominal diseases and severesymptoms, a rapid diagnosis is paramount to avoid irrepairableorgan damage. In the past, an exploratory laparotomy wasoften quickly resorted to as a diagnostic aid in acute abdomenin cattle with no clear diagnosis. Today, many farmers willconsent to exploratory laparotomy ,only when the prognosisis good and the procedure has a reasonable chance of beingcurative. If the prognosis is poor, an exploratory laparotomyis avoided by the surgeon as well as by the farmer as it isexpensive and causes unnecessary pain to the patient andoften the animal is no longer marketable. Thus, the goal ofabdominal surgery should be treatment, rather than diagnosisof the disease. To achieve this goal, all available and pertinentnon-invasive diagnostic aids must be employed to establisha diagnosis before surgery is performed.
Keywords: Diagnostic ultrasonography, Non-invasive,Abdomen,Cattle
Diagnostic ultrasonography provides a window for non-invasive visualization of abdominal organs and gastro-intestinal viscera, which are otherwise difficult toexamine. This sonographic information can be used todecide a) if surgical intervention is indicated, b) toformulate a prognosis based upon the abnormalitiesdetected and c) can be used to monitor response tomedicinal treatment. The abdominal contents can easilybe evaluated sonographically with the 3.5 and 5.0 MHztransducers; however, higher frequency transducers are

also used to yield superior images of the gastro-intestinal viscera (Singh et al. 1993).
Previously, the diagnosis of bovine abdominaldisorders was based on history, routine physicalexamination, haemato-biochemical analysis andradiography. Hematological and biochemical tests whichare non-specific for diagnosis of fore-stomach affectionsand are only indicative of health status of the animal.With the advent of modern diagnostic instruments,ultrasonography is being used for early confirmatorydiagnosis of ruminant disorders. Abdominal radiographyis limited in its application in large animals becausetheir size produces practical difficulties in achievingradiographs of diagnostic quality.
In recent years, ultrasonography has beensuccessfully used to examine the affections ofcompound stomach in cows and buffaloes. In cattle themost routinely encountered affections are:- Traumaticreticuloperitonitis, Omasal impaction, Left displacementof the abomasums and Right displacement of theabomasums.
However, in buffaloes, ultrasonography has beenmore successfully used to diagnose reticulardiaphragmatic hernia with > 85% accuracy (Mohindrooet al. 2007).
Reticular Diaphragmatic Hernia
Recent studies conducted on various affections offorestomach indicate that incidence of diaphragmatichernia is high in buffaloes as compared to cows (Singh2002).
For visualising reticular diaphragmatic herniaultrasonographically, non sedated animal is restrained

in standing position and the right lateral wall of the thoraxfrom the 4th to 7th intercostal space is shaved andsmeared with transmission gel for optimal transmissionof ultrasonic waves and is visualized with the help of3.5 MHz microconvex transducer.
Ultrasonographically, the presence of biphasicreticular motility at the level of the 4th and 5th intercostalspaces, instead of right 6th and 7th intercostal spaces atthe level of elbow, indicates reticular herniation into thethorax. Reticular motility is observed but the amplitudeof contractions is comparatively less (Saini et al. 2007).
Traumatic reticuloperitonitis
In cattles with traumatic reticuloperitonitis,ultrasonography can be used to identify morphologicalchanges in the region of the cranial, ventral or caudalreticular wall (Braun et al. 1993). The caudo-ventral
reticular wall is the most frequently affected, often inassociation with the cranio-dorsal blind sac of therumen.
The changes in the contour of the reticulumdepend on the severity of the inflammatory changes.Deposits of fibrinous tissue interspersed with fluidpockets are frequently seen on the reticular serosa.Ultrasonographically, these appear as echogenic areascavitated by hypoechogenic areas.
Reticular abscess is seen as a sequel to a foreignbody syndrome ( Kumar et al. 2008). Reticularabscesses have an echogenic capsule of varyingthickness, which surrounds a homogeneoushypoechogenic to moderately echogenic centre.Abscesses are usually caudo-ventral to the reticulum,but may be cranial or lateral to the reticulum. It ispossible to drain abscesses through an ultrasound-guided transcutaneous incision (Braun and Gerber1998).

Omasal impaction
Chronic omasal impaction as a clinical entity is difficultto define and is usually diagnosed at necropsy whenthe omasum is enlarged and firm. Ultrasonographicallyimpacted omasum in buffaloes may be diagnosed byenlarged amotile omasum, non visibility of omasalleaves and a prominent distal acoustic shadow, whilein cows, it is diagnosed by amotile omasum covering alarge area right side (Udehiya 2007).
intercostal spaces on the left side are, with transducerheld parallel to the ribs. With left displacement of theabomasum, the wall of the rumen often remainsimmediately adjacent to the abdominal wall in the ventralregion. When the transducer is moved dorsally, itbecomes apparent that the wall of the rumen is pushedmedially and can no longer be imagedultrasonographically. Instead the abomasum is seen,located between the abdominal wall and rumen.

Left displacement of the abomasums
An ultrasonographic examination is useful to confirmthe diagnosis of left displacement of the abomasum indoubtful cases (Braun et al. 1997). 3.5 MHz transduceris moved from ventral to dorsal region at the last three

Right displacement of the abomasums
For Right displacement of abomasums the areaimmediately caudal to the last rib and the caudal two tothree intercostal spaces on the right side are examinedventro-dorsally with the 5MHz linear transducertransducer held parallel to the ribs (Braun et al. 1997).In animals with right displacement of the abomasum,the liver is displaced from the abdominal wall and cannotbe imaged. The abomasum is seen where the liver wouldnormally be ie; immediately adjacent to the rightabdominal wall.

Abstract
A field investigation was conducted during 2010-11 to 2012-13 at Jabalpur,Madhya Pradesh to study the effect of nutrientmanagement and cropping system on productivity and soilmicrobial growth under different rice based cropping systemsin Madhya Pradesh. The 4 different cropping systems (CS1-Green manuring sunhemp-Rice-Wheat, CS2-Rice-Chickpea-Sesame, CS3-Rice-Berseem, CS4-Rice-Veg.pea-Sorghum)and three nutrient managements M1- 100% Organic (1/3 Nthrough each of FYM, Vermicompost and Neem oil cake),M2-100 % Inorganic (100 % NPK through fertilizers), M3-INM(50%NPK through fertilizer+50% N through organic sources)with 3 replications in Strip plot design. The soil of theexperimental field was sandy clay loam in texture, neutral inreaction (7.3), normal EC (0.52), low in OC (0.72%), mediumin available N (264.05kg/ha) and P (12.8 kg/ha) and high inK(285.2 kg/ha). The highest grain yield of 34.78 q/ha wasrecorded from rice-wheat-green manuring cropping systems.And the best nutrient management for growth of microorganisms is organic nutrient management and rice-wheat-green manuring cropping system.

Rice and wheat are grown in a sequence on an areaabout 2.7 million hectares in Punjab and contribute 80%in the total food pool of the state of Punjab (DAGP 2011).Madhya Pradesh is relatively underdeveloped withregards to agricultural productivity rural employment andeconomic status as compared to most of the Indianstates. During kharif, growing of rice is a tradition andis widely accepted depending upon farmers socio-economic conditions. However, in rabi, there are feweroptions for the stakeholders to take a profitable andsuitable crops. Under these circumstances, theygenerally follow rice-wheat, rice-mustard and rice-winter

vegetables under partially or assured irrigation and rice-fallow, rice-utera under rainfed situation as also reportedby Chitale et al. (2011). Any modification to the existingsystem with a tendency to decline the productivity ofrice crop will neither be sustainable nor acceptable tothe farming community unless and untill it is stable overthe time, maintains the soil health and sustains theenvironment in one hand and could also meet the dailyrequirements of human and animals (Samui et al. 2004).Oilseeds and pulses including vegetables and fodderare receiving more attention owing to their higher prices.
Therefore to get maximum yield from the existingcropping system the organic farming must be practiced.This help to get the best food grain production and willimprove the soil health as well Prasad et al (2005).Butorganic manures will not give higher grain yield in thefirst year so the inorganic fertilizers were used aloneas well as in combination in the form of INM for betterresults. To prove this, an experiment was carried out toevaluate growth, yield attributes and effect on soilmicrobial growth by application of organic, inorganicand integrated nutrient management in different ricebased cropping systems including oilseeds, pulses,vegetable and fodder crops.
Material and methods
A field experiment was conducted during 2010-11 to2012-13 at the research farm of Jawaharlal Nehru KrishiVishwa Vidhyalaya, Jabalpur on a sandy clay loam soil.The soil of the experimental site had a pH 7.4, EC0.51dS/m and organic carbon 0.7%.The available soilnitrogen ,phosphorus and potash were 264,12.6 and282 kg/ha, respectively. The bulk density of the soil was1.35 Mg/m3.The factors studied included 3 nutrientmanagenment practices viz., organic manure (ONM),

chemical fertilizers and integrated nutrient (50:50) (INM)and 4 cropping systems viz., rice-durum wheat-greenmanuring, rice-chickpea-sesame, rice-berseem (fodder+ seed), rice-vegetable pea-sorghum (fodder) in stripplot design with 3 replication. The crop varieties grownwere Pusa sugandha Basmati-5 in rice, MPO-1106 indurum wheat, JG-24 for gram, JB-1 for berseem, Arkelfor vegetable pea during winter season and TKG-55 insesame and MP Chari in sorghum during summerseason. These crops were raised with recommendedagronomic practices.
In organic manure treatment nutrients wereapplied through farm yard manure. The manure wasapplied on the nitrogen equivalent basis for each crop.The nutrient composition of FYM was 0.5, 0.25, 0.5%N,P2O5 and K2O respectively. For the weedmanagement, mechanical measures were adopted andfor insect pest management, neem oil (Azadiractin0.03%) was applied as and when required under organicnutrient management. In chemical fertilizer treatment,nutrient were applied through chemical fertilizers viz.,urea, single super phosphate muriate of potash whileplant protection was done through recommendedpesticides, when required. The recommended dose offertilizers for rice, wheat, chickpea, sesame, vegetablepea, sorghum and berseem. 120:26.4:33.3,120:26.4:33.3, 20:60:30, 30:60:30, 20:26.4:16.6,100:22:25 and 20:26.4:16.6kg N:P:K/ha. In integratednutrient management (INM) treatment 50% of nitrogenwas supplied through farm yard manure and rest 50%through chemical fertilizers and the plant protection wasdone by adopting integrated pest management practicesand application of Phorate granules was done insorghum to protect from the attack of shoot borers. Inrice-wheat green manuring cropping system, sunhempwas grown before rice and 35 days old crop wasincorporated in soil as green manure. PhosphorusSolubilizing Bacteria was used for inoculation in allcrops.
Rice was transplanted in the first week of Julyand harvested in the second week of October. Thewinter crops (wheat, chickpea, vegetable pea andberseem) were sown in the second week of Octoberand harvested in second week of February. The summercrops (sesame and sorghum) were sown in third weekof February and harvested in first/second week of June.The calculated dose of organic manures was applied2-3 weeks prior to sowing of kharif crops, 1 week priorto rabi and summer crops. The rainfall received duringthe experimental period was 1023, 1062 and 1011 mmin 2010-11, 2011-12 and 2012-13, respectively. Duringkharif, rice received 3 irrigation (each for 7.5 cm depth)each year. During rabi 5, 4, 3 and 12 irrigation were
provided for wheat, chickpea, berseem (fodder + seed)and vegetable pea, respectively each year. Duringsummer sesame and sorghum received 4 and 6irrigations, respectively each year. The market price oforganic rice is 2500 (Rs/q) and the value of rice underinorganic and INM is 1900 (Rs/q).
Result and discussion
Growth and Yield attributes
In this experiment the effect of three nutrientmanagement practices (100% organic, 100% inorganicand INM) and four cropping systems i.e. Basmati rice -wheat - green manauring, Basmati rice - chickpea -sesame, Basmati rice - Berseem (Fodder and seed) andBasmati rice - vegetable pea - sorghum (fodder) ongrowth, yield attributes and soil health were testedduring 2012-13 on the same plot and site. The highestplant height of 71.10 cm was obtained from inorganicfertilized plots and 71.81cm in Rice- wheat -greenmanuring cropping system. But maximum number ofeffective tillers/m2 were obtained from organic manures(292.5/m2) and rice-vegetable pea-sorghum croppingsystem (294.4/m2).The highest grains per panicle wasrecorded from inorganic nutrient management of 73.33and 74.44 from rice-vegetable pea-sorghum croppingsystem. But the maximum grain yield of 35.12 wasobtained from inorganic nutrient management, 33.19q/ha from INM and 32.96 q/ha from organic nutrientmanagement and 34.78 q/ha from rice-wheat-greenmanuring cropping system followed by 34.45 q/ha inrice-chickpea-sesame cropping system.
Changes in soil properties
The soil of the experimental field was sandy clay loamin texture and neutral in reaction (Soil pH 7.4) with bulkdensity of 1.35 g/cm3 at 0-30 cm depth. Its electricalconductivity was 0.51 dS/m and has 7.0 g/kg OC. Itcontains 264, 12.6 and 282 kg/ha available N, P and Kcontents, respectively. On the basis of data pertainingto various soil-properties after the completion of thirdyear, some remarkable changes in soil properties overtheir initial status were observed due to the effect ofdifferent cropping systems under varying nutrientmanagement practices as obtained from Annual Report2011-12.
The treatments receiving organic nutrientmanagement either fully (100% organic) or partially(INM) exhibited improvement in OC content of the soil
148
and the effect of 100% organic nutrient managementwas more pronounced in this regard. The N contentsshowed rising trend under all cropping system with100% organic, inorganic as well as INM nutrition, whileP and K contents were almost stabilized with thesetreatments. The P contents exhibited slight reductionwith 100% inorganic nutrition. As regard the changesin chemical and biological properties of soil after 3 yearof experimentation, it was observed that treatmentsreceiving organic nutrient management either fully(100% organic) or partially (INM) exhibited improvementin organic carbon content and microbial population (viz.total fungi, Bacteria, AZB, PSB and ACT) of the soiland the effect of 100% organic nutrient managementwas more pronounced in this respect. The populationof fungi was 45.4 x 104,bacteria it was 51.8 x106,azatobacter 27.1 x 106 and phosphorus solubilizingbacteria 14.5 x 106.Thus it was recorded that the organicnutrient management record the maximum growth ofmicroorganisms. As the market value of organic produceis more as compared to inorganic produce as alsoreported by Upadhyay et al. (2011).

Abstract
The correlation coefficient amongst seed yield and itsattributing characters for wheat crop under rice-wheat croppingsystem was computed. It is found that seed and straw yieldwere significantly and positively associated with all the growthand yield parameters in wheat crop.
Keywords: Wheat, Correlation coefficient, seed yield,growth parameters, yield parameters.
The challenges for agriculture are immense. In the next25 years, the challenges for agriculture will not only beto meet the food needs of the world's expandingpopulation, but also to undertake food supply in amanner that is sustainable for present and futuregenerations. Tremendous quantities of nutrients arerequired to produce the food necessary to feed the worldin any given year. Poor as well as indiscriminatemanagement of these nutrients in many parts of theworld has led to environment pollution and thedegradation of this resource base, particularly in thedeveloping world. To meet agricultural production andsustainable intensification goals over the short and long-term, plant nutrient and soils need to be managedproperly.
Integrated nutrient management system is animportant component of sustainable agriculturalintensification. The goal of INM is to integrate the useof all natural and man-made sources of plant nutrients,so as to increase crop productivity in an efficient andenvironmentally benign manner without diminishing the

capacity of the soil to be productive for present andfuture generations. It seeks to maintain or improve soilfertility for sustaining the desired level of crop productionand crop productivity through optimization of the benefitfrom all possible sources of plant nutrients in anintegrated manner.
Wheat requires high quantity of nutrients toharness their potential yield. However, it is unaffordableto poor and subsistence farmers of the state. Applicationof inadequate and unbalanced quantity of fertilizers towheat crop results in low crop yield as well asunsustainable productivity. Therefore, a long-termexperiment has been initiated on integrated nutrientmanagement in rice-wheat system at Jabalpur (MP)since kharif season 1987-88 to maintain the sustainableand high grain yields of wheat without degradation ofsoil health under irrigated production system. Thepresent paper deals with the studies during the year2002-03 and 2003-04.
Materials and methods
The soil of the experimental field was neutral in reaction(soil pH 7.7) and normal in EC (0.38 dS m-1) with mediumorganic carbon content (6.9 g kg-1) and analysingmedium in available N (260 kg ha-1), P (16 kg ha-1) andhigh in available K (448 kg ha-1) contents. The rainfallwas 1266 and 1756 mm during the two consecutiveyears i.e. 2002-03 and 2003-04. There were 12treatments (Table 1). Different organic manures viz. FYM(1.22-0.55-0.90% and 1.18, 0.48, 1.02% N, P, K in 2002-

03 and 2003-04 respectively), wheat straw (0.49-0.09-1.80% and 0.50, 0.10, 1.68% N, P, K in 2002-03 and2003-04 respectively) and green leaf manure ofsunnhemp (2.21-0.48-1.77% and 2.30, 0.51, 1.79% N,P, K in 2002-03 and 2003-04 respectively) wereanalyzed and their quantities required to substitute aspecified amount of N as per the treatments wascalculated. Recommended 100% NPK for both cropswas 120 kg N + 60 kg P2O5 + 40 kg K2O/ha applied asper the treatment through urea, single super phosphateand muriate of potash respectively. The experimentswere laidout in randomized block design with 4replications. Wheat cv. Lok-1 was grown by using seeds100 kgha-1 in rows 20 cm apart. Other cultural practicesviz. weed management and plant protection measureswere followed as per recommendation in the state. Thedata of both years were pooled when differencesbetween the years were not significant. Correlationcoefficients of the observations were estimatedaccording to the method suggested by Gondane et al.(1995).
Results and discussion
At 30 days after sowing, Plant height and number oftillers per m2 expressed positive association with theplant height and number of tillers per m2 at 90 daysafter sowing and at harvest respectively (Table 2).Graphical presentation of Correlation Coefficient ofattributing characters with Seed Yield, straw yield andharvest index also given below. Effective tillers per m2
showed positive association with the earhead lengthand number of grains per earhead. Anwar et al. (2009)also found that Number of tillers per plant had positivedirect effect on grain yield per plant. Growth parametersshowed positive association with the entire yieldattributing characteristics. Akram et al. (2008) revealedthat number of grains per spike positively associatedwith seed yield in wheat crop. Seed and straw yieldshowed strong positive association with all thevegetative and yield attributing parameters. Seed andstraw yield expressed very strong positive correlationwith each other. While harvest index expressed negativeassociation with all the growth parameters, yieldattributing characters, seed and straw yield. It can beconcluded that all the above growth and yield attributingcharacters strongly contributed to the seed and strawyield.

Abstract
Investigations were conducted during kharif and rabi seasonsof 2011-12 and 2012-13 at JNKVV, Jabalpur to study the effectof organic nutrient management practices on growth, yieldattributing characters, yield and soil fertility in rice-basedcropping systems. Nutrient management through organics playa major role in maintaining soil health due to build up of soilorganic matter, beneficial microbes, enzymes, besidesimproving soil physical, chemical and biological properties andto achieve sustainable soil fertility and crop productivity. Theavailable N, P2O5, and K2O were significantly higher in legumebased cropping systems during both the seasons of the studythan non-legume system. GM-basmati rice- wheat andbasmati rice-berseem cropping systems were the bestcropping systems that increase availability of nutrients in thesoil. Application of 1/3 VC + 1/3FYM +1/3 NEOC + Panchgavyahad higher available nitrogen, phosphorus and potassiumduring both the crop years . Application of FYM, vermicompost,NEOC and Panchagvya significantly increased plant height(cm), tillers/m2, number of grains/panicle and grain yield (q/ha) in both the years.

In India rice (Oryza sativa L) - Wheat (Triticum aestivumL) is the dominant cropping system in Indo-Gangaticplains. Rice and wheat are the world's two most impor-tant cereal crops contributing 45% of the digestible en-ergy and 30% of total protein in the human diet. Ap-proximately 12.5 m ha area under this system contrib-uted to 25% total food grain production of India (Singhet al. 2011). About 33% of India's rice and 42% of wheatis grown in this rotation. Rice and wheat are consid-ered as major constituent of National Food Security bycontributing about 76% of total food grains productionto the national basket.

Continuous cropping of rice-wheat systemcreated many fold problems such as deteriorated soilstructure, build up of pests including weeds, decliningfactor productivity, development of nutrients deficiencyand decrease in profitability etc. To deal all these issues,a comprehensive and collaborative effort was neededto bring all the key resources together for enhancingthe productivity. Rice-wheat cropping system is highlynutrient exhaustive and therefore, its continuous usehas depleted inherent soil fertility, causing deficiencyof several nutrients.
Intensive cultivation and growing exhaustivecrops have made the soil deficient in macro as well asin micronutrients. The success of any cropping systemdepends upon the appropriate management ofresources including balanced use of manures andfertilizers. The cultivation of legumes has made radicalimprovement in the farming community.

(2007) reported that thephysicochemical properties of the soil improvedsignificantly by the addition of organic manures and thatthere was very little change due to inorganic fertilizers.It is apparent that there is a need to generate moreinformation on integrated nutrient recommendations forcropping system for sustained crop production throughincreased soil productivity in long term experiments.Organic manures in agriculture adds much neededorganic and mineral matter to the soil. The organicmatter added is an indispensable component of soil,and plays an important role in maintenance andimprovement of soil fertility and productivity. The propermanagement of these make it possible to increase theefficiency of use of soil and added nutrients. Nutrientmanagement through organics play a major role inmaintaining soil health due to build up of soil organicmatter, beneficial microbes, enzymes, besides

improving soil physical, chemical and biologicalproperties and to achieve sustainable soil fertility andcrop productivity.
Awareness about improved quality of foodproducts, problems of health hazards and environmentalissues both at global and national level is increasing inrecent years. There is a great demand for high qualityproducts and organically grown foods in the internationalmarket and can capitalize on its potential to go fororganic farming on a large scale. India, with its variedagro-climatic conditions and agricultural biodiversity, ismost suited for organic farming. It is necessary toeducate the farmers about the scientific methods oforganic farming so that their income will increasegradually. Organic farming is also preferred becauseof increasing consumer demand for safe, high quality,ethical organic foods. Organically produced productsalso fetches good returns.
Material and methods
The present investigation is the part of the "NetworkProject on Organic Farming". The soil of theexperimental site was sandy clay loam (Sand - 54.10%, Silt - 24.21 % and Clay - 21.69 %) having pH of 7.3,EC 0.39 dS/m in the top 15 cm soil. The available N,P2O5 and K2O were 260, 10.20 and 296 kg/ha,
respectively. The organic carbon content of the soil was0.68%. The field capacity, bulk density, porosity andwater holding capacity of the surface soil were 30.3%and 1.3 Mg/m3, 52.6 % and 22% respectively. Thedesign followed was split plot with two main plots(cropping system) and five sub-plots (Nutrientmanagement) treatments and three replications. Thetwo cropping systems were gm-basmati rice - durumwheat and basmati rice-berseem. The organic nutrientmanagement practices were N1- 1/3 FYM+1/3NC+1/3VC, N2- Panchgavya alone, N3-1/3 FYM+1/3NC+1/3VC+ Panchgavya, N4- BD-501 and N5- BD-501 +Panchgavya. These manures were applied based onthe nitrogen equivalent basis and nutrient requirementof each crop. The organic manures according to thetreatment details were applied two weeks before sowingof crops.
Results and discussion
Growth and yield attributing characters of rice viz. plantheight (cm), effective tillers/m2, number of grain/panicleand grain yield (q/ha) were increased with treatment N3-(1/3 FYM+1/3NC+1/3VC+panchagvya) during both theyears. Organic nutrient management practices hadsignificantly increased available nitrogen, phosphorusand potassium content in soil as compared to initial

Duringharvest of kharif crop increase in available N (277,278kg/ka), P2O5 (13.43, 14.30 kg/ha) and K2O (292, 309kg/ha) and during harvest of rabi crops increase inavailable N (280, 282 kg/ha), P2O5 (14.23, 14.43kg/ha)and K2O (378, 376 kg/ha) were observed. Basmati rice-berseem cropping system was the best cropping systemthat increase availability of nutrients in the soil.Swaminathan (2005) reported that use of panchagvyawith combination of other organic manure (FYM, VCand NEOC) increased photosynthetic activity in the plantand also increased bacteria, yeast, actinomycetes,photosynthetic bacteria and certain fungi availability inthe soil.FYM worked as soil conditioner and supplyingplant nutrients which resulted in improvement in soil
fertility and grain yield.
The mineralization of N in soil and due to highenzyme activities in the soil amended with organicmanures will increase the transformation of nutrients(Singh et al. 2008). Similarly, the P availability in soilincreased due to use of organics. During decompositionof organic manure, various organic acids will beproduced which solubilize phosphate and otherphosphate bearing minerals and thereby lowers thephosphate fixation and increase its availability. SrinivasRao et al. (1997) recorded higher potassium release inearthworm casts. Singh et al. (1999) reported thatimprovement in soil fertility was attributed to addition ofFYM and other organics which stimulated the growthand activity of microorganisms. They participate in thebiological cycling of elements and transformation of the

mineral compounds and thus increases the availabilityof nutrients in soil.
The available nutrients in soil had significanteffect of cropping systems. This was due to nodulationof legume crops which fixes atmospheric N and Ncontent in soil increases. As there is synergistic relationof N with P, K and S, this helps in increasing the nutrientcontent in soil irrespective of nutrient managementpractices. Inclusion of pulses in cropping system isbeneficial, as these improve the soil fertility and cropproductivity. The benefit of including legumes incropping cycle which improves soil fertility status wasreported by Das et al. (2010). Similarly, Varalakshmi etal. (2005) reported that the legume cropping helped toincrease the available N, P2O5 and K2O content of thesoil. The available N, P2O5, and K2O were significantlyhigher in legume based cropping systems during boththe seasons of the study than non-legume system.

Abstract
Glycinebetaine is a compatible solute that accumulates incertain cyanobacteria, algae, plants and microorganisms inresponse to various types of stress is in comparative studiesof wild-type and NaClr mutant strain of Synechococcus spp.has been found accumulate, amino acid glycinebetaine under400 mM NaCl. In present study we isolate mutant strainSynechococcus spp. medium containing 400 mM NaCl,survival of NaClr mutant strain and therefore this concentrationof NaCl had been chosen and employed in these experiments.Glycinebetaine and several compatible solutes protectcyanobacteria but 400 mM NaCl concentration enhancedaccumulation of Glycinebetaine in wild type strain. NaCl r

Cyanobacteria are oxygenic photosynthetic prokaryotesand important biomass producers which are widespreadin diverse environments including freshwater, oceanicand terrestrial habitats (Eiji Suzuki et al. 2010). Salinityis a serious agro-economical problem which leads tometabolic alterations and graded reduction in the plantgrowth in terms of all the growth parameters. Microalgaeare rich sources of proteins, carbohydrates and fattyacids. Unicellular eukaryotic microalgae have specialimportance due to the simplicity of their structuresshowing all metabolic activities and having similaritieswith higher plants. Microalgae differ in their adaptabilityto salinity and other stress conditions.
Living organisms are frequently exposed tovarious kinds of environmental stress in their naturalhabitats and they have developed mechanisms thatallow them to withstand such stress. One such

mechanism involves the accumulation of compatiblesolutes, which are defined as water-soluble organiccompounds of low molecular mass that are nontoxic athigh concentrations (Chen and Murata 2002). Thecompatible solutes, also called osmolytes, includesugars, amino acids and their derivatives, polyols,betaine and ectoines (Surasak Laloknam et al. 2010).Glycinebetaine is a major compatible solute; it is anamphoteric compound and extremely soluble in water.The molecular features of betaine allow it to interactwith both the hydrophobic and the hydrophilic domainsof macromolecules. In previous invitro studies it wasindicated that betaine stabilizes the structure and activityof enzymes and maintains the integrity of membranesagainst the damaging effects of excessive salt, cold,heat, and freezing (Gorham 1995). Betaine is found ina wide variety of prokaryotes, eukaryoticmicroorganisms, higher plants, and animals (Wilken etal. 1970; Galinski and Trüper 1982; Yancey et al. 1982;Mohammad et al. 1983; Hanson et al. 1985). Severalworker studies on salt stress protein involved in highsalt concentration in cyanobacteria which help theorganism in protecting them against the deleteriouseffect of the stress condition (Fernades et al. 1993; Sotoet al. 1999).
Materials and methods
Organism and culture conditions
Cyanobacteria Synechococcus spp. obtained from Bluegreen algae Department IARI New Delhi and its NaCltolerant mutant were grown in BG-11 medium by main-taining the culture at 26 ± 1°C with a photosyntheticphoton flux density of approximately 50 mol m-2 sec-1
and a light regime of 18 h light/6 h dark.

Extraction and purification of amino acids
Amino acids were extracted from the cultures of wild-type Synechococcus spp. and its NaClr mutant strainfollowing the method of (Singh and Bisen 1994) grownat 26±1oC, at a photon fluence rate of 50 µmol m-2s-1
with intermittent light and dark period (18/6 h) in BG-11medium in the presence and absence of 400 mM NaCl.Cells of both the strains were harvested bycentrifugation. A simple treatment of all pellets with 70%ethanol (v/v) followed by incubation for 6 h at 4oC indark resulted in nearly complete extraction of aminoacids. Filtrate was then subjected to rotary evaporationat 35oC by using a rotary vacuum evaporator. Theresidue was dissolved in 2 ml of 0.2 M lithium citratebuffer (pH 2.2) followed by filtrations through syringefilter of size 0.4 µm (Millipore, USA). The amino acidconcentrations in the samples were determined by thefluorescence of its O-phthaldehyde derivative (Rajendra1987) by using high Performance Liquid Chromatograph(LC-10A, Shimadzu) using linear gradient of methanoland distilled water.
Results and discussions
Cells were grown in BG11 containing 400 mM NaCl(wild-type) and (NaClr mutant strain) for 7 days andamino acid contents were determined. The results(Figure 1.C and 2.D) suggested that the protective effectof Glycinebetaine activity might have been due toenhancement of under salt stress condition. The resultsshowed that on amino acid analysis wild-type (with andwithout NaCl Fig. 2. B, D) and NaClr mutant strain. NaClrmutant strain accumulated very high level of glycinebetaine but slightly increased (Chauhan et al. 1999a).(Fig 2.D and 1.C) under NaCl stress as compared to itswild-type counterpart because organism moreresistance against salt stress compare to wild-typewhereas wild-type with NaCl glycinebetaine quicklyincreased but cell growth rate slow as compare to mutantstrain and same results found in arginine (Fig. 1.C).(1.C and 2.D) Glutamine slightly increased at stresscondition to compare with the normal condition.Aspartate, proline and glutamate were induced toincrease about two-fold. Glycine betaine is synthesizedby a two-step oxidation of choline via betaine aldehyde.Choline has a vital role as the precursor forphosphatidylcholine, a domi-nant constituent ofmembrane phospholipids in eukaryotes. Despite this,a large proportion of free choline is diverted toglycinebetaine in cyanobacteria Bala (Rathinasabapathiet al. 2000). Several genes have been found to
contribute to osmotic stress expressed duringtranscription. Probably these genes code for synthesisof compatible solutes as well as salinity stress proteinsthat proteins produced in NaClr mutant strain. Theseproteins help the organism in protecting them againstthe deleterious effect of the stress condition (Fernadeset al. 1993; Soto et al. 1999).

The total number of species prevalent during surveyof two Zones Adhartal and Lalmati of 9 wards of Jabalpurcity is 40 species that belonged to 26 plant families.The information reveals the use of various parts of plantto cure several serious disease out of 40 plants speciesstudied during survey in case of 11 plant species rootpowder or extract is used to cure the disease , in 4plant species stem powder or extract is used to curethe disease and in15 plant species bark was used tocure the diseases, Leaves were used to treat diseasein case of 33 plant species, flower were used to treatdisease in case of 14 plant species and seeds wereused to treat disease in case of 3 plant species andfruit were used to treat disease in case of 14 plantspecies (Table 1).
The medicinal plants used to cure differenthuman diseases out of 40 plants species studied duringsurvey in case of 13 plants species were used to curerespiratory diseases, 5 plants species were used to curerheumatism diseases, 7 plants species were used tocure hearts diseases, 12 plants species were used tocure urinary diseases, 27 plants species were used tocure skin diseases, 4 plants species were used to curediabetes diseases and 18 plants species were used tocure stomach diseases.
Discussion
The medicinally important plant collected from theJabalpur used to treat various diseases like cold fever,cough, diarrhea, dysentery, skin diseases, laxative,diabetes and jaundice. This is constant with the othergeneral observation which reported earlier. In relationto medicinal plant studies by the Indian traditionalsystems of medicine like sidha and Ayurvedha(Anonymous 1992). The information on medicinal valuesof plants was acquired through personal interview ofVaidhya, Hakeem and by local healers. The knowledgeof these not only whole plant traditional healers whichrevealed that but each part of the plant like seed, barkand root and flower etc. play significant role in curing tocure different disease like skin disease, eye disease,respiratory disease, digestive and other disease ( Vermaand Dahake 2010).
Conclusion
Various parts such as roots, stem, barks, leaf, flowers,fruits and seeds were reported to be useful in curingseveral devastating human disorder and diseases. Theethnic values of the plants are very important inproviding valuable information to the local healers. Thestudy revealed that the local people of Jabalpur citystill continue to depend on medicinal plants at least fortreatment of primary health problems. Therefore thetraditional knowledge used by local healer's workstreasured.

Abstract
A field investigation was conducted at AICRP on ForageCrops, Department of Agronomy, Jawaharlal Nehru KrishiVishwa Vidyalaya Jabalpur (MP) during Kharif 2012 with theobjective of to determine the relative performance of new pearlmillet genotypes in combination of nitrogen levels . Thetreatments consists of four new pearl millet genotypes (RBB-1, PAC-981, Raj Bajra Chari (NC) and Giant Bajra (NC)) andfour nitrogen levels (0, 30 ,60 and 90) under factorialrandomized block design replicated thrice .The variety RBB-1with 90 kg N/ ha proved significantly superior in producingmaximum green fodder yield (348.0 q/ha), dry matter yield(85.08 q/ha) and crude protein yield (6.59 q/ha) and maximummonetary advantage (Rs 69851) and proved mostremunerative with benefit: cost ratio of 4.87.
Keywords: Pearl millet, nitrogen levels, varieties andeconomics
In India, the requirement of green fodder was 611.99Mt against the availability of only 224.08 Mt (Anonymous2006). Similar pattern has been observed in dry fodder,green fodder and concentrate i.e. 32.4%, 46.5% and69.3% as against the requirement of 62.6, 313.0 and14.3 million tonnes for current livestock population inMadhya Prdesh. Because of increasing pressure ofhuman population on the country priority is given to graincrops and preferential use of low-capability land forforages and multiplication ratio is very narrow in mostof fodders. The efficiency of milch as well as droughtanimals largely depends upon the supply of quantityand quality of ration in which green fodder plays a vitalrole. In the recent years shortage of fodder has remained

Mehrez and Zraslox (1977). The dry matter yield wasrecorded.
Result and discussion
Effect on growth pattern and yield attributes
The plant height, number of tillers per plant, leaf areaindex, and dry matter accumulation by plant had directlycorrelated with the green fodder yield. Plant height,number of tillers per m row length, leaf area index, anddry matter accumulation at different growth stages wassignificantly higher in RBB 1 than other varieties (Table1). This was attributed inherent genetic character ofvariety. The finding are in concurrence with report ofAICRP-Forage Crops (2012). Application of nitrogen60kg/ha which was statistically at par with the 90 kg N/ha significantly increased plant height(146.02 cm),number of tillers per plant (30.56), leaf area index(9.3)and dry matter accumulation (76.67 q/ha) at differentgrowth stages over control 0 and 30 kg N/ha. As aprincipal, a soil deficient in plant nutrient improves cropgrowth when supplied with a particular nutrient inquestion. These results are in conformity with those ofBabu et al.(1995). RBB 1 also resulted significantlyhigher number of tillers per m row length than othervarieties. In case of nitrogen @ 60 kg/ha which was atpar with 90 kg N/ha, significantly increased number oftillers per plant over control 0 and 30 kg N/ha (Table 1).
The varieties RBB 1 attained maximum plantheight (174.9) ,number of tillers (28.63) and LAI (9.5)than other genotypes. The quality of fodder isdetermined by leaf -stem ratio and it was almostcomparable among all the varieties, however varietyRBB 1 was numerically superior (0.59) to others(0.56,0.51 and 0.48, respectively) with regard to leaf-stem ratio.
Effect on yield
Green and dry fodder yield were significantly higher inRBB 1 than PAC 981, Raj Bajra Chari (NC) and GiantBajra (NC). Application of nitrogen 90kg /ha significantlyincreased green (309.2 q/ha)and dry fodder yields(76.67 q/ha) of pearl millet over control, 0 and 30kg N/ha which was at par with 60 kg N/ha. The fodder yield,being a function of the cumulative effect of growthparameter such as plant height, number of tillers per mrow length plant which were higher with 90 kg N/ha,resulting in higher forage yield under this treatment.The increases in fodder yield with increasing level of
167
nitrogen could also be explained by better nutritionalcondition of the crop as supported by higher nitrogenuptake when fertilized with 90 kg N/ha. Greater uptakeof nutrients by application of nitrogen probably favoredbetter growth and development of crops, resulting intoincreased fodder yield. These finding corroborate theresults of Hooda et al. (2004) who recorded a significantincrease in fodder yield with increased level of nitrogen.
RBB 1not only produced maximum yield of pearlmillet fodder but also good quality of fodder than othervarieties. Crude protein yield (%) in dry fodder of varietyRBB 1 was significantly higher (6.59) than other varieties(5.97, 5.54 and 048, respectively). This might be dueto that higher nitrogen content in this variety. Nitrogenis an integral part of protein as a result higher crudeprotein found in dry fodder of RBB 1 than other varieties.The similar results were also obtained by AICRP-ForageCrops (2012) that reported significantly higher crudeprotein in variety RBB 1 than rest of varieties. This maybe due to inherent genetic characters of varieties andhigher content of nitrogen which is the major constituentof amino acids and protein and decreased the pectin,cellulose, hemicelluloses and proportion of

Effect on Economics
Genotype RBB 1 (5.03) with respect of B-C ratio beingclose to Raj Bajra Chari (NC) (4.66) than Giant Bajra(NC) and PAC-981resulted into lesser B-C ratio.Application of nitrogen i.e.90 kg N /ha markedly gavemaximum B-C ratio 4.92 than other levels.

Abstract
Field investigations were conducted at Krishi Nagar farm,Adhartal Department of Agronomy, JNKVV Jabalpur duringkharif season of 2010 and 2011 to study the "Effect of plantinggeometries on nutrient uptake of improved rice varieties underdepths of planting in system of rice intensification" keeping into maximize the production efficiency and monetary advantagein rice by adopting suitable planting geometry, varieties anddepth of planting. The experiment comprises on 18 treatmentcombinations consisted with three planting geometry, as mainplot treatment and three varieties (MR-219, WGL-32100 andPS-3) as sub plot treatments and two depths of plantingshallow (2.5 cm) and normal (5.0 cm) as sub-sub plottreatments were tested in split-split plot design with threereplications. Results showed that the greater amount ofnitrogen (128.09 and 131.34 kg/ha), (31.02 and 31.73 kg/ha)and potassium (111.68 and 119.80 kg/ha) was absorbed by25 x 25 cm planting geometry as compared to other 20 x 20cm and 30 x 30 cm planting geometries. Significantly greateramount of nitrogen (132.34 and 143.86 kg/ha) phosphorus(30.71 and 32.64 kg/ha) and potassium (109.36 and 116.31kg/ha) was absorbed by MR-219 as compared to othervarieties viz. WGL-32100 and PS-3. The shallow depth ofplanting, crop absorbed significantly more amount of nitrogen(125.09 and 129.53 kg/ha), phosphorus (24.01 and 25.90 kg/ha) and potassium (103.58 and 111.01 kg/ha) as comparedto normal depth of planting.

Rice is the most important Cereal food crop of thedeveloping world and the staple food of more than 3billion people or more than half of the world's population.One fifth of the world's population more than a billionpeople depend on rice cultivation for their livelihoods.Asia, where about 90% of rice is grown, has more than200 million rice farms. India is considered to be one ofthe original centers of rice cultivation covering 44.6million hectares, producing 132 MT of rice with an
average productivity of 2.96 t ha-1 (Pandian 2009).Around 65% of the total populations in India eat riceand it accounts for 40% of their food production India isthe world's second largest producer of white rice,accounting for 20% of all world rice production. Worldproduction of rice has risen steadily from about 200million tonnes of paddy rice in 1960 to over 678 milliontonnes in 2009. Rice-based production systems providethe main source of income and employment for morethan 50 million households (IRRI, 2008 data).Worldproduction of rice has risen steadily from about 200million tonnes of paddy rice in 1960 to over 678 milliontonnes in 2009, Rice production in India is an importantpart of the national economy.
Among the different agronomic practices, plantinggeometry and depth of planting play a vital role inachieving higher yield levels of improved varieties ofrice. It is because the proper distributions of crop plantper unit area and efficient utilization of available nutrientand other resources as well as environment. Thereforepresent experiment was conducts for study the nutrientuptake influence by planting geometries, varieties anddepths of planting.

having planting geometry as main plots, varieties assub plot treatments and depths of planting shallow (2.5cm) and normal (5.0 cm) as sub-sub plot treatments.The area of each plot was 3 x 7 m2. Seedlings weretransplanted with an average of one seedling per hill inthe SRI method of planting. Application of 10 t FYM/hawas given uniformly to all the plots before final puddlingand leveling. Fertilizer with a uniform dose of 120: 60:40 kg per hectare N, P and K through urea, DAP andMOP was applied in all the plots. Half dose of nitrogenand full dose phosphorus and potassium were appliedas basal application just before transplanting. Theremaining half dose of nitrogen was applied in two splitdoses at tillering and panicle initiation stages. Standardcultural practices were carried out till the crop wasmature. The sample of grains and straw were taken atthe time of harvest of crop components in both the yearsand then they were allowed to dry in an oven till to reachthe constant weight. after this, theses samples weregrinded into fine powder with the help of mortar andpistal. After this, N, P and K contents of these sampleswere analyzed by Kjeldahl's digestion method asdescribed by Piper (1950) for nitrogen, ammoniumvandomolybdo phosphoric acid (Bartous reagents)yellow colour method Koeings and Jackson (1942) forphosphorus and flame photometer method as describedby Black (1965) for potassium. The data was analyzedstatistically as per the procedure prescribed for split-split plot design (Panse and Sukhatme 1995) to obtainedanalysis of variance. The analysis of variance If thevariance ratio (F test ) was found significant at 5% levelof significance then standard error of mean ( SE±) andcritical differences (CD).

Significantly greater amount of nitrogen,phosphorus and potassium was absorbed by 25 x 25cm planting geometry in compared to other 20 x 20 cmand 30 x 30 cm planting geometries. The maximumremoved of N, P and K in 25 x 25 cm planting geometrymay be due to its stronger and proper plant stands forgrowth requirement resulted into higher grain yield incompared to other two 20 x 20 cm and 30 x 30 cmplanting geometries. Significantly greater amount ofnitrogen, phosphorus and potassium was absorbed byMR-219 in compared to other varieties viz., WGL-32100and PS-3 (Table 1&2). The maximum removed of N, Pand K in MR-219 may be due to its physiologically highgrowth requirement resulted into higher grain yield thanthe other two varieties. Thus, the nutrient uptake bythese three varieties in accordance with the nutrientcontent in grain and straw and the grain yield. Similarresults are also reported by Singh et al. (2004). Thedepths of planting cause significant variations in removalof nutrients from the soil. The shallow depth of planting,crop absorbed significantly more amount of nitrogen,phosphorus and potassium in compared to normal depthof planting. This may be due to the readily availabilityof nutrients in lower zone of soil in oxidized conditions.

Abstract
Temperature is fluctuating during crop season and geneticimprovement is a prerequisite for improvement in heattolerance in chickpea. Selection on the basis of grain yield, apolygenically controlled complex character, is usually not veryefficient as such, but selection based on its componentcharacters could be more efficient. Genetic analysis werecarried out using thirty promising lines chosen from ChickpeaImprovement Project and grown in three differentenvironments viz normal, late and very late sown, consideringphenological and morphological traits viz days to flowerinitiation, days to 50% flowering, days to pod initiation days tomaturity, plant height, primary branches, secondary branches,total number of pods per plant, effective pods per plant, seedsper pod, 100-seed weight, biological yield, harvest index andseed yield per plant. These lines were screened for heattolerant which, can withstand in the high temperatureconditions, to find out genetic variability for yield and itscontributing traits during rabi 2010-2011. Estimates of variousparameters for assessment of genetic variability viz mean,range of variability, genetic advance and coefficient of variationhelps the breeder in deriving suitable plant types by bringingimprovement in quantitatively inherited traits, which will directlyeffects the crop yield. Effective pods per plant had the highestphenotypic and genotypic coefficient of variations followed,by 100 seed weight, harvest index, total number of pods perplant, biological yield, secondary branches, seeds per podand plant height. High heritability coupled with high geneticadvance as percentage of mean were recorded for plantheight, secondary branches, total number of pods per plant,effective pods per plant, 100 seed weight, biological yield andharvest index. This indicates the presence of additive geneeffects. Genotypes, ICCV 07102, JG 16 and JG 21 are foundsuitable under late sown conditions. Whereas, genotypes GG2, ICC 4958, ICCV 06301, ICCV 07102, ICCV 07117, JG 18,JG 21 and JG 22 are suitable for growing under very latesown and the genotypes viz., ICCV 07102, JG 21 and JG 22are found to be suitable for all the dates of sowing.

Chickpea is the most widely grown in South Asia andthe Mediterranean region (Saxena 1990, Singh andOcampo 1997, FAO 2003). It is the third most importantpulse crop as well as an important source of humanfood and feed; it also helps in improve soil fertility,particularly in dry lands. It is sensitive to environmentalfluctuations, leading to instability in acreage andproduction over the years. Under present scenario ofclimate change and high cropping intensity the farmersprefers the early duration genotypes suitable for latesown and very late sown cultivation particularly inMadhya Pradesh. In this regards yield of chickpea isinfluence being grain yield is a quantitative trait and isa multiplicative effect of number of component traitswhich is influenced by environments. Breeding effortshave contributed substantially to improve yield potentialregional adaptation through resistance or tolerance toabiotic and biotic stresses, plant type and graincharacteristics.
Quantum of genetic variability and the extent, towhich heritable and non-heritable variations are relatedto the characters, determine the extent of geneticamelioration. Yield is a highly complex character as itis controlled by a large number of genes and greatlyinfluenced by the environment.
Thus, direct selection for yield may not be veryeffective, several morphological traits andenvironmental conditions influences the yield directlyor indirectly. Thus, selection of superior genotypesbased on yield as such is not effective. To achieve thisobjective, a thorough understanding of yield contributingtraits, genotypic and phenotypic coefficient of variance,heritability and genetic advance is necessary. Thus, inthe present study, an attempt was made to get thecomprehensive information on these aspects inchickpea under different environments.

The experimental area occupied wasquite uniform in respect of topography and fertility. Theexperimental material comprised of 30 promising linesof chickpea covering 27 desi and 3 Kabuli types. Thesegenotypes were grown in a randomized completelyblock design with three replications under three differentdates of sowing viz; normal (19.10.11), late (24.12.10)and very late (30.01.12). Each Plot size was 4.0 m x0.90m consisting of 2 rows of 4m length, the row to rowdistance was 45 cm and plant to plant spacing was 10cm.
Fertilizer was applied in the ratio of 20N:60P2O5:40K2Okg/ha. The experiment was conducted withrecommended agronomic practices. Five plants fromeach replication were randomly selected andobservation were made for the characters days to flowerinitiation (DFI), days to 50% flowering (F 50%), days topod initiation (PS), days to maturity (P 50%), plant height(cm), number of primary and secondary branches, totalnumber of pods per plant, effective pods per plant, seedsper pod, 100 seed weight(g), biological yield(g), harvestindex (%) and seed yield per plant (g). The data wereprocessed for statistical analysis and genetic variabilityincluding heritability and genetic advance were doneby the methods given by Hanson et al. (1956) andJohnson et al. (1955) respectively.
Results and discussion
The phenotypic coefficient of variations was higher inmagnitude than its corresponding genotypic coefficientof variations for all the characters studied under threeenvironments. This indicates the influence of theenvironment on the expression of these characters. Theresult and discussion on phenotypic coefficient ofvariations had been presented on pooled analysis basiscovering all environments.
The characters effective pods per plant had the highestphenotypic and genotypic coefficient of variationsfollowed, by 100 seed weight, harvest index, totalnumber of pods per plant, biological yield, andsecondary branches, seeds per pod and plant heightwhich were in accordance with the findings of Khorgade(1985), Sharma et al. (1990), Kumar et al. (1991) andSandhu et al. (1991). Primary branches had moderate
phenotypic and genotypic coefficient of variation whileremaining traits like days to flower initiation, days to50% flowering, days to pod initiation and days to maturityexhibited low phenotypic and genotypic coefficient ofvariation.
In any crop improvement programme, the mostbasic information required by a breeder is the extent ofthe inheritance capacity of the genotype for differentcharacter under consideration. In fact, the variability ofbiological population is an outcome of geneticconstitution of the individual make up of that populationin relation to prevailing environments. Such studiesenable the breeder to have maximum selectionresponse if the variance exhibited by the populations islargely due to additive genetic variance. Substantialgenetic variance was observed for majority ofcharacters, in the study. In order to draw some validconclusion about the possibilities of the improvementof the various characters, estimation of heritabilityvalues are very essential. As the genetic advanceestimates are dependent on the unit of characters undermeasurement, hence genetic advance expressed aspercentage of mean was calculated in order to haverelative comparison of expected genetic gain forquantitative characters for one generation of selectionin hypothetical selection programme. Heritability andgenetic advance estimates varied from high, mediumto low in all the three environments for differentcharacters (Table 1).
Highest heritability was observed for plant heightand seed yield per plant followed by the characters daysto flower initiation, 100 seed weight, harvest index, andbiological yield. The characters seeds per pod, primarybranches, days to 50% flowering, days to flower initiationand total number of seeds per pod had shown very lowheritability. Similar findings have also been reportedby Jeena and Arora (2001), Jivani and Yadvendra(1989), Patel and Babbar (2004), Jeena et al. (2005),Saleem et al. (2005).
Among all the traits which showed high geneticadvance as percentage of mean were 100 seed weight,followed by effective pods per plant, harvest index,biological yield, plant height and total pods per plant.Low genetic advance as percentage of mean recordedin characters days to pod initiation, days to maturity,days to flower initiation, days to 50% flowering ,primarybranches, secondary branches and seeds per pod. Theabove results are agreement with the findings of Durgaet al. (2007) and Vaghela et al. (2008).
High heritability coupled with high geneticadvance as percentage of mean were recorded for plant

Abstract
Three hundred eighty seven genotypes of chickpea wereevaluated for nine characters viz. days to 50% flowering, daysto maturity, plant height, number of primary branches per plant,number of seeds per pod, number of pods per plant, biologicalyield, harvest index and grain yield per plot to estimate geneticparameter and association for yield and its components.Considerable genetic variability was observed for all thecharacters under studied. Grain yield per plot showed highlysignificant and positive phenotypic association with biologicalyield and number of seeds per pod. Genotypic correlation fordependent variable grain yield per plot was highly significantand positive with number of seeds per pod, biological yieldper plant and harvest index. An observation of genotypic pathanalysis for grain yield per plot revealed maximum direct effectthrough number of seeds per pod, followed by harvest index.
Key words : Chickpea, variability, correlation and pathanalysis
Chickpea (Cicer arietinum L.) is one of the mostimportant legume crop of Madhya Pradesh. Breedingefforts have contributed substantially to improving yieldpotential global yield increased from 591 kg /ha in 1975to 818 kg/ha in 2005 (FAOSTAT data 2006), regionaladaptation through resistance or tolerance to abioticand biotic stresses, plant type and grain characteristics.Quantum of genetic variability and the extent to whichheritable and non-heritable variations are related to thecharacters, determine the extent of genetic amelioration.Yield is a highly complex character as it is controlled bya large number of genes and greatly influenced by theenvironment. Thus direct selection for yield may not bevery effective, several morphological and quality traitsinfluence the yield directly and indirectly. These traitsare simply inherited and less influenced by theenvironment as compared to yield. So selection basedon these traits has better chance of successes in

comparison to selection for yield per se. The genotypiccorrelation indicates the extent to which the twocharacters are under the control of the same set ofgenes or have the same physiological basis for theirexpression.
Material and methods
The experimental materials for the present studyconsisted of 387 germplasm collections of chickpea.These genotypes were grown in a RandomizedCompletely Block Design with two replications duringRabi 2007-08 at Jawaharlal Neharu Krishi VishwaVidhyalaya, Jabalpur. Each plot consisted of one rowof 4 m row length. The row-to-row and plant-to-plantdistance was 30 cm and 10 cm respectively.Recommended dose of fertilizer was applied in the rowsbefore sowing. Observations were recorded on fiverandomly selected plants on nine characters.
Result and Discussion
Maximum genotypic coefficient of variation (Table 1) wasobserved for the character biological yield per plant(43.9) while minimum value was reported for days tomaturity (3.06). Maximum phenotypic coefficient ofvariation observed for number of seeds per pod (146.48)and minimum for day to maturity (3.89). Heritability wasmaximum for days to 50% flowering (97.8%), geneticadvance as percentage of mean was maximum forbiological yield per plant. These findings are inagreement with the results of Mandal and Bahl (1980),Kumar et al. (1983), Sharma et al. (1990), Tripathi andArora (1991), Sandhu et al. (1991), Mishra et al. (1994),Wahid and Ahmed (1999), Kumar et al. (2001), Ali etal. (2002), Usmani et al. (2005).

Abstract
RILs generate wide genetic variability among the lines andthe homozygosity of the alleles of important traits within thegenotype and would be of immense use to identify the traitsfor mapping. RILs population derived from two contrastingcultivars were subjected to principal component analysis toobtain precise information on yield and quality related inter-componental traits. On the basis of principal componentanalysis, only five principal components (PCs) exhibited morethan 1.8 eigen value and showed about 68.34% variabilitywere identified. The PC1 showed 25.81%, while PC2, PC3,PC4 and PC5 exhibited 17.22%, 9.56%, 8.58% and 7.16%variability respectively, among the RILs for the traits understudy. Rotated component matrix revealed that each principalcomponent separately loaded with various yield and qualityattributing traits. The PC1, PC2, PC3 and PC5 were mostlyrelated to yield attributing traits whereas PC4 was related toquality traits. As PC1 was constituted by most of the yieldattributing traits, intensive selection procedures can bedesigned to bring about rapid improvement of dependent traitsfor yield by selecting the lines from PC1. Similarly, for qualityaspect a good breeding programme can be initiated byselecting the lines from PC4. PC scores of RILs in these fivePCs suggested that RIL 2-36 was ranked first for yieldattributing traits,RIL 2-52 for quality traitswhereas RIL 2-50was reported best for both yield and quality traits. IdentifiedRILs may be used as donor to improve the yield and qualitytraits in varietal development programme and some of therice RILs may also be used directly for cultivation purposes.

than 70% of human caloric intake and main source ofprotein for poor people in developing countries.Itprovides 21% of global human per capita energy and15% of per capita protein. Calories from rice areparticularly important in Asia, especially among the poor,where it accounts for 50-80% of daily caloric intake.Asia accounts for over 90% of the world's production ofrice, with China, India and Indonesia producing the most.Rice can also be found in cereals, snack foods, brewedbeverages, flour, oil, syrup and religious ceremonies toname a few other uses. In India it is cultivated in anarea of 45.54 million hectares with a production of 99.18million tones and productivity of 2177kg ha-1(Anon2012).
Analysis of related to yield and their attributingtraits and their compression with the increasingpopulation is a important aspects by which a good resultmay be made to fulfil the current demand. Severalstatistical procedures have been developed and appliedto analyse the different data's in many crops and in themsome of the procedures found to be very good tocalculate the associations of different traits. In differentstatistical analysis Principal Component Analysis (PCA)is a powerful tool in modern data analysis because it isa simple, non-parametric method for extracting relevantinformation from confusing data sets. This techniquewas initially floated by Pearson (1901) and laterdeveloped by Hotelling (1933). With minimal effort PCAprovides a roadmap for how to reduce a complex dataset to a lower dimension to reveal the sometimes hiddeninformation that often underlie it (Shlens, 2009). Itreduces the dimensionality of the data while retainingmost of the variation in the data set. PCA accomplishesthis reduction by identifying directions, called principalcomponents, along which the variation in the data is

maximal (Anderson, 1972 and Morrison, 1978). By usinga few components, each sample can be representedby relatively few numbers instead of by values forthousands of variables (Ringer, 2008). Thus, the primarybenefit of PCA arises from quantifying the importanceof each dimension for describing the variability of a datasetin more interpretable and more visualized dimensionsthrough linear combinations of variables that accountsfor most of the variation present in the original set ofvariables.Considering the importance of PCA aninvestigation was carried out on rice RILs with anobjective to identify the minimum number of componentswhich can explain maximum variability out of the totalvariability, to rank genotypes on the basis of PC scoresand to identify superior RILs based on yield and qualitytraits at Jawaharlal Nehru KrishiVishvaVidyalaya,Jabalpur (M.P.) India.
Meterial and methods
The experimental material comprised of 91Recombinant Inbred Lines (RILs) population derivedfrom a cross between two diverse parents, JNPT 89(Tropical japonica) and JR 75 (Indica) by single seeddescent method. Each RIL along with parents wereplanted in main plot containing 24 hills arrangedaccording to randomized complete block design (RCBD)with three replications at the rate of one seedling perhill. At the time of transplanting spacing of 20 cmbetween plant to plant and between row to row of thesame distance were maintained. The standard
agronomic practices were adopted for good cropgrowth.The observations were recorded as per thestandard procedure. The statistical analysis of data onindividual characters was carried out using mean valuesof randomly selected plants from each genotype in eachreplication.
Result and discussion
PCA was performed on rice RILs for yield and theirattributing traits and also for quality contributing traitsto identify the important components and genotypeshaving better characters related to rice improvementprogrammes. Out of twenty seven principal components(PCs), only five PCs exhibited more than 1.8 eigen valueand showed about 68.34% variability among the traitsstudied. Because of five PCs having more eigen valuesand variability so in this case these five PCs wereincluded for further explanation.
Scree plot explained the percentage of varianceassociated with each principal component obtained bydrawing a graph between eigen values and principalcomponent numbers. PC1 showed 25.81% variabilitywith eigen value 6.97 which then declined gradually(Fig.1). Rotated component matrix revealed that the PC1which accounted for the highest variability (25.81%) wasmostly related with traits such as panicles weight perplant, grain yield per plant, number of filled spikeletsper panicle, number of spikelets per panicle, plantheight, biological yield per plant, spikelet density,

average panicle weight, panicle index and paniclelength. PC2, PC3, PC4 and PC5 exhibited 17.22%,9.56%, 8.58% and 7.16% variability respectively amongthe lines for the traits under study. (Table 1). In PC2 thetraits viz., days to 50% flowering, days to heading anddays to maturity were more related. The PC3 wasdominated by number of tillers per plant, number ofleaves per plant and number of productive tillers perplant. The fourth principal component was more relatedto hulling%, milling% and head rice recovery% whereasPC5 was more related to grain breadth and 1000 grainweight (Table 2).
To rank the genotypes in the top 10 principalcomponent scores (PC scores) for all the lines wereestimated in these five components. RIL 2-36 hadhighest PC score followed by 2-75, 2-69, 2-79, 2-91, 2-61, 2-3, 2-56, 2-31 and 2-50 in PC1 indicated that theyhad high panicles weight per plant, grain yield per plant,number of filled spikelets per panicle, number ofspikelets per panicle, plant height, biological yield perplant, spikelet density, average panicle weight, panicleindex and panicle length.
The highest PC scores of RIL 2-46 followed by2-78, 2-67, 2-69, 2-66, 2-47, 2-4, 2-59, 2-58 and 2-25in PC3 exhibited high number of tillers per plant, numberof leaves per plant and number of productive tillers perplant. Similarly, decreasing order of PC scores of RIL2-52, 2-49, 2-46, 2-53, 2-45, 2-64, 2-40, 2-50, 2-74 and2-22 in PC4 exhibited high value of quality traits viz.,hulling%, milling% and head rice recovery %. In PC2
RIL 2-41 recorded the highest PC score followed by 2-69, 2-28, 2-8, 2-67, 2-56, 2-21, 2-88, 2-91 and 2-52indicated that they had high days to heading, days to50% flowering and days to maturity whereas in PC5RILs 2-70 exhibited the highest PC score followed by2-6, 2-34, 2-40, 2-31, 2-9, 2-12, 2-30, 2-65 and 2-67indicated that they had high value of grain breadth and1000 grain weight. On the basis of top 10 PC scores ineach principal component, RILs are selected andpresented as summarised form in Table. 1.
Discussion
Principal component scores were calculated for all theRILs in five principal components and utilized in findingRILs superior for different combination of phenotypictraits. A high value of principal component score of aparticular RIL in a particular principal componentdenotes high value for those variables in that RIL inwhich the component is representing. Thus, thesescores can be utilized to propose precise selectionindices whose intensity can be decided by variabilityexplained by each of the principal component. Accordingto the first PC score, RIL 2-36 had highest score followedby 2-75, 2-69, 2-79, 2-91, 2-61, 2-3, 2-56, 2-31 and 2-50 indicated that they had high panicles weight per plant,grain yield per plant, number of filled spikelets perpanicle, number of spikelets per panicle, plant height,biological yield per plant, spikelet density, averagepanicle weight, panicle index and panicle length. Thehighest PC scores of RIL 2-46 followed by 2-78, 2-67,2-69, 2-66, 2-47, 2-4, 2-59, 2-58 and 2-25 in PC3exhibited high number of tillers per plant, number ofleaves per plant and number of productive tillers perplant. Since, PC1and PC3 are concentrated by most ofthe major yield contributing traits which explainmaximum variability, an intensive selection procedurescan be designed to bring about rapid improvement ofdependent traits i.e., grain yield by selecting the linesfrom these components. Likewise, decreasing order ofPC scores of RIL 2-52, 2-49, 2-46, 2-53, 2-45, 2-64, 2-40, 2-50, 2-74 and 2-22 in PC4 exhibited high value ofquality contributing traits viz., hulling%, milling% andhead rice recovery %. Thus, breeder can select lineswith highest score having desirable combination ofquality traits for further desired breeding programme.In PC2 RIL 2-41 recorded the highest PC score followedby 2-69, 2-28, 2-8, 2-67, 2-56, 2-21, 2-88, 2-91 and 2-52 indicated that they had high days to heading, daysto 50% flowering and days to maturity whereas in PC5RILs 2-70 exhibited the highest PC score followed by2-6, 2-34, 2-40, 2-31, 2-9, 2-12, 2-30, 2-65 and 2-67indicated that they had high value of grain breadth and

1000 grain weight. Results of PC2 can be discussed intwo aspects; first the RILs having high PC scores canbe utilised for developing late maturity with high yieldingtrait containing varieties and second the RILs havinglow PC scores can be utilised for making early and extraearly maturity varieties including high yield potentials.
Principal component analysis highlights thecharacters with maximum variability so, intensiveselection procedures can be designed to bring aboutrapid improvement of yield and quality traits. PCA alsohelp in ranking of genotypes on the basis of PC scoresin corresponding component. From the abovediscussion, it is clear that the RIL 2-36 hold the firstposition followed by 2-75, 2-69, 2-79, 2-91, 2-61, 2-3,2-56, 2-31 and 2-50 for yield traits, whereas RIL 2-52hold the first position followed by 2-49, 2-46, 2-53, 2-45, 2-64, 2-40, 2-50, 2-74 and 2-22 for quality attributingtraits. However, for both yield and quality traits RIL 2-50 found to be best. The derived information of thisresearch on rice RILs would be very useful to selectpotentially breeding lines for future rice improvementprogramme (Khan et al. 2012).These selected RILs maybe used as parent for the transfer of desired yield andquality traits in the suitable cultivars in crop improvementaspects. RIL 2-50 was the best line for both the yieldand quality traits, which can be used directly forcultivation purposes.

Abstract
A field investigation was conducted to study the effect of soilmoisture on growth, nutrient status of healthy and malformedpanicles in different mango varieties at Fruit Research Station,Imalia, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur(M.P.). A total of twenty four treatment combinations ofirrigations and varieties were tested in factorial randomizedblock design with three replications. The results of studyrevealed that an increase in soil moisture content delayedthe bud initiation and panicle emergence in mango. Highersoil moisture enhanced the content of N, P, K and Zn in theleaves of healthy panicles bearing shoots and higher contentof Fe, Mn and Cu was in leaves of malformed panicles. Amongthe varieties minimum intensity (2.9m-2) and severity (25.7%)of malformation was recorded in Langra followed by Amrapaliand Sunderja.

Mango (Mangifera indica L.) is having wider adaptabilitywith respect to soil, climate and altitude for its successfulcultivation. It is being grown on 2.04 million hectaresarea with a total production of 22.7 million tones whichworks out to a low average productivity of 11.1 metrictones per hectare (Anonymous 2010 Kumar et al. 2009).Globally, number of problems have been identified inmango production, out of which malformation has beenfound. Tahir et al. (2003) reported that moisture stressdiscouraged the emergence of late season flushes thatultimately minimize the rate of malformation as tree doesnot exhausted due to the occurrence of useless flushes.The etiology of malformation has yet been discovered,however, effective management measures are still
unknown. Presently, there is a lack of researchinformation on the soil moisture content which mightplay a significant role in management of malformation.Therefore, an attempt has been made to study the effectof soil moisture on macro and micro nutrient content inmalformed and healthy panicles bearing shoots ofdifferent verities of mango.
Material and method
A field experiment was conducted at Fruit ResearchStation, Imalia, JNKVV during 2010 and 2011. The soilof experimental site was clay in texture (58.4% clay,22.5 silt and 20.1% sand) having pH 7.2, mediumavailable N (302 kg ha-1), high in P (22.6 kg ha-1) and K(430.7kg ha-1) with medium organic carbon (0.70%). Theexperiment consisted of three varieties (V1:Amrapali,V2:Sunderja and V3: Langra) and eight irrigation levels(I1: control (without irrigation), I2 : Irrigation at 30 daysafter rains over, I3 : Irrigation at 60 days after rainsover, I4 : Irrigation at 90 days after rains over, I5 :Irrigation at 30 and 60 days after rains over, I6 : Irrigationat 30 and 90 days after rains over, I7 : Irrigation at 60and 90 days after rains over and I8 : Irrigation at 30, 60and 90 days after rains over). Healthy and malformedpanicles detached separately from node for recordingfresh weight. To determine the dry weight, these paniclewere chopped and oven dried at 60 ±20c till get constantweight. The content of nitrogen (Mc Donald 1978),phosphorus (Koenig and Jhonson 1942), potassium(Hanway and Haidal 1952) and micronutrient weredetermine by Atomic Absorbtion Spectrophotometer (Luand Chacko 2000) in healthy and malformed bearingshoots separately.

Result and discussion
Different growth parameters viz. number of leaves,length of panicles, fresh and dry weight of paniclesclearly indicates that increase in number of irrigationhad the positive effect on the number of leaves andlength of panicles as well as biomass accumulation inhealthy and malformed panicles. In general, morepanicle length was noted with healthy panicles and freshand dry weight was higher with malformed bearingshoots. The higher number of leaves and longestpanicles were recorded under irrigations at 30, 60 and90 days after rains over. The increase in number ofleaves and length of panicle might be due to theabundant availability of moisture to the plants whichmight increase the availability of water and solutes forabsorption. Higher absorption of water and nutrientspromote the growth and development of tree in termsof number of leaves and panicle size. Results of Singhet al. (1994) are in the close conformity with presentfindings.
The scheduling of irrigation had marked effecton content of major nutrients (N, P and K) and proteincontent in the leaves of healthy and malformed bearingshoots. The significant improvement in content ofnutrients was observed with the increasing number ofirrigation and reduction in intervals. The three irrigationsat 30, 60 and 90 days after the rains recorded the highercontent of N (2.72 and 2.47%), P (0.345 and 0.315 ppm)K (77.1 and 60.71 ppm) and protein (17.03 and 15.43%)in leaves of healthy and malformed bearing shoots,respectively, whereas it reduced with either the increasein intervals of irrigation or decrease in number ofirrigations. The increase in content of N, P, K and proteinwith the increase in number of irrigations might be dueto the fact that the availability of higher moisture lowerdown the temperature of the which surface provides achance to trees roots for absorbing more water andsolutes as compared to roots of stress tree (Singh et al.2009). The positive relation of content of major nutrientswith number of irrigations was also noted byChhattopadhyay and Patra (1992) who were of the viewthat greater uptake of nutrient in pomegranate was dueto its greater absorption by the roots and higheravailability of soil moisture. The various cultivars didnot show marked variations in relation to content of N,P and K in leaves of healthy and malformed bearingpanicle leaves. However, slight variations in healthy andmalformed shoots were observed. The healthy shootshad a higher content as compared to leaves ofmalformed shoots. The variation in content of N, P andK in leaves of different mango varieties was reportedby Singh et al. (2009).
The copper, iron and manganese content weresignificantly higher in leaves of malformed shoots ascompared to healthy, whereas zinc content showed thereverse trend (Table 1). These findings are in closeconformity with the findings of Singh et al. (1991) andSingh et al. (1997). The increased in moisture contentincreased the content of Zn (22.65 to 29.64 and 21.65to 27.02 ppm), Cu (6.63 to 9.71 and 7.58 to 10.12 ppm),Fe 137.4 to 196.9 and 154.4 to 210.9 ppm) and Mn(55.1 to 84.5 and 70.1 to 99.5 ppm) in the leaves ofhealthy and malformed shoots, respectively. It mightbe due to higher moisture content in soil which helpsthe uptake of these nutrients. The increased content ofnutrients was reported under mulching byChattopadhyaya and Pattra (1992) in pomegranate andByun et al. (1989) in ber. The greater lateral spreadwith enhanced root growth in the upper layers of soil inmulched tree which might be due to the presence ofhigher moisture and comparatively low temperature atupper surface. Increase in the root hairs in mulchedtree may increase the water and solute absorptivesurface of the root in the vascular tissue which mayprovide more conductive condition to roots forabsorption and translocation of mineral and water tothe plant.

Abstract
A field experiment was conducted to study the effect of soilmoisture on growth, nutrient status of healthy and malformedpanicles in different mango varieties at Fruit Research Station,Imalia, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur(M.P.). A total of twenty four treatment combinations ofirrigations and varieties were tested in factorial randomizedblock design with three replications. The results of study revealthat an increase in soil moisture content delayed the budinitiation and panicle emergence in mango. The minimumintensity (2.7 m-2) and severity (24.7%) of malformation wasrecorded under restricted soil moisture conditions. The highermoisture content in soil increased the intensity (4.5 m-2) andseverity (42.7%) of malformed. The higher soil moisture levelenlarged the panicle in terms of length (29.5 and 8.6cm), fresh(37.3 and 70.6 g) and dry weight (21.4 and 28.2 g) of healthyand malformed panicles, respectively. Among the varietiesminimum intensity (2.9m -2) and severity (25.7%) ofmalformation was recorded in Langra followed by Amrapaliand Sunderja. The maximum infestation of malformation wasrecorded under south direction of tree canopy.

Mango (Mangifera indica L.) is having wider adaptabilitywith respect to soil, climate and altitude for its successfulcultivation. It is being grown on 2.04 million hectaresarea with a total production of 22.7 million tones whichworks out to a low average productivity of 11.1 metrictones per hectare (Anonymous 2010, Kumar et al.2009). Globally, number of problems has been identifiedin mango production. Which are associated with scionand rootstock. Malformation is the most threateningmalady that causes great economic losses and limitsthe mango production. In floral malformation, a flowerof malformed panicle enlarges and get crowded with

hypertrophied axis of panicles and becomes unable toproduce fruits. The intensity and severity of disorderare closely associated with plant type, season,atmospheric humidity, temperature and status of nutrientand moisture in soil. The moisture stress stimulatedgrowth of floral bud and delayed the vegetative phase.On the other hand, decrease in temperature aftermoisture stress proved to be beneficial for flowerinitiation. Therefore, an attempt has been made to studythe effect of status of soil moisture on malformation indifferent verities of mango.
Material and method
A field experiment was conducted at Fruit ResearchStation, Imalia, JNKVV during 2010 and 11. The soil ofexperimental site was clayey in texture (58.4% clay, 22.5silt and 20.1% sand) having ph 7.2, medium availableN (302 kg ha-1), high in P (22.6 kg ha-1) and K (430.7kgha -1) with medium organic carbon (0.70%). Theexperiment consisted of three varieties (V1:Amrapali,V2:Sunderja and V3: Langra) and eight irrigation levels(I1: control (without irrigation), I2 : Irrigation at 30 daysafter rains over, I3 : Irrigation at 60 days after rainsover, I4 : Irrigation at 90 days after rains over, I5 :Irrigation at 30 and 60 days after rains over, I6 : Irrigationat 30 and 90 days after rains over, I7 : Irrigation at 60and 90 days after rains over and I8 : Irrigation at 30, 60and 90 days after rains over). Twenty four plants of eachvariety were selected randomly and replicated thrice ina factorial randomized block design. Ten shoots of eachtreatment from north, east, west and south direction ofplant canopy were tagged randomly and emergence ofbud and panicle were recorded. Tagged shoots werealso used to assess severity, panicle length and dryweight accumulation in healthy and malformed panicles.

Healthy and malformed panicles detached separatelyfrom node for recording fresh weight. To determine thedry weight, panicle were chopped and oven dried at 60±20c till get constant weight. The number of healthy andmalformed panicles per square meter was recorded withthe help of quadrate.
Results and discussion
Early initiation of bud and emergence of panicles werenoted while the plants were not irrigated or irrigationdelayed upto 90 days. Moreover, period of bud initiationincreased with increase in irrigation frequency, hencemoisture stresses encouraged the reproductive phasei.e. bud initiation as well as emergence of panicles. Thepresent observations conformity with the findings of Luand Chacko (2000) who reported that soil water deficitpromote earlier and more intense flowering in mango.The results of Tahir et al. (2003) supported the presentfindings.
After withdrawal of rains as the number ofirrigation increases increased the intensity and severityof malformation. The maximum intensity and severityof malformed panicles (4.5 m -2 and 42.7%) wererecorded under higher soil moisture increased throughapplication of three irrigations at an interval of 30 daysafter rain over. The least intensity (2.7m-2) and severity(24.7%) of malformed panicle were noted under withoutirrigation closely followed by irrigation at 90 days afterrains. This might be due to the assimilation of morecarbohydrate during moisture stress which promotesthe reproductive phase of plant. These findings are inproximity of Singh and Ram (1997) and Gaur andChakrabarti (2009).
The maximum intensity (4.5m-2), severity (36.0%)and length (9.1cm) of malformed panicles was recordedunder north direction whereas, minimum intensity(2.7m -2), severity (27.7%) and length (7.1cm) ofmalformed were noted under south direction of plantcanopy. It was also noted that higher moisture contentin soil adversely increased the intensity (4.5m-1), severity(42.7%) and length (8.6 cm) of malformed panicle. Themalformed panicle length and its severity and intensityboth increased with the change of direction from southto north. It might be because of higher moisture levelwhich increased the nutrient uptake. These findings arein agreement with the findings of Gaur and Chakrabarti(2009) who reported that the malformation developmentwas promoted by high rainfall. Thakur et al. (2003) foundthat incidences of floral and vegetative malformationwere higher on the north-facing as compared to and
lowest on the south-facing side of the tree.
Irrigation treatment with different varieties showedthe markeable variations for intensity and severity ofmalformation. The higher intensity (5.6 m-2) as well asseverity (51.8%) of malformation was recorded whenSunderja plants were irrigated thrice at 30, 60 and 90days after rains whereas the lowest infestation wasrecorded with variety Langra at the same level of soilmoisture. These findings are in agreement with thefindings of Singh and Ram (1997), Badiyala andLakhanpal (1990) and Gaur and Chakarabarti(2009).The intensity and severity of malformationchanged with the change of directions of plant canopy.Cultivars, Langra found least susceptible formalformation followed by Amrapali and Sunderja in allthe directions of canopy. These findings are inagreement with the findings of Thakur et al. (2000).

Abstract
The study was designed to measure resource use efficiencyin Chick pea production of Narmadapuram division of MadhyaPradesh State. In present investigation we used the doublelog type Cobb-Douglas type of production function. The sampleof 216 Chick Pea farmers were selected from which input-output data collected based on 2012-13 rabi cropping season.Functional analysis of chick pea crop revealed that seed rate,fertilizers and manures, plant protection, irrigation facilities,human labour and machine labour, manure and fertilizers,had the elasticity of 0.052, 0.147, 0.199, 0.039, 0.037 and0.11 respectively and was statistically significant. The valueof MVP in respect of seed rate (1.48), plant protection (4.476)and fertilizers and manures (3.067) were more than unit leveland the MVP value of irrigation facilities (0.166) human labour(0.638), machine labour (0.257) were found to be less thanunit level.
Key words: Chick pea, profitability, resource useefficiency, marginal value of product
Chick Pea (Cicer arietinum) is the most important pulsecrop of India. Chick Pea occupies about 37% of areaunder pulses and contributes about 50% of the totalpulse production of India. Chick pea is major pulsescrop in the state of Madhya Pradesh which occur thearea 3043.4 thousand ha and the production is 3290.3thousand tones. In Narmapuram division rabi seasonof chick pea the second most important crop coveringan area of 88.2 thousand ha and the production is 140.6thousand tones (Year 2012).
In Narmadapuram division, Hoshangabad andHarda are the selected districts. The presentinvestigation aims to examine cost and returns analysisof principle crop of Narmadapuram division.

Materials and methods
The present study was carried out in Narmadapuramdivision of of Madhya Pradesh, where chick pea is thecommonly grown as rabi season crop by the farmersNarmadapuram division comprises of two districtsnamely, Hoshangabad and Harda. The data of 216cultivators were collected and compiled for the year2012-13.
Resource use efficiency
In present investigation we used the Cobb-Douglas typeof production function - Resource use efficiency. TheCobb-Douglas production function was used forestimating the resources productivity of variableresources used in selected crop.
The Cobb-Douglas type of production function was usedand is defined as:
Y = a X1 b1. X2 b2. X3 b3. X4 b4. X5 b5. X6 b6
where,Y = Dependent variable (gross income in Rs)a = ConstantX = independent variableX1 = Value of seed in RsX2 = value of fertilizer in RsX3 = value of human labour in RsX4 = value of plant protection measures in RsX5 = irrigation charge in RsX6 = value of machine labour in Rsb1…b6 = Regression coefficient of concern variableMarginal Value Productivity (MVP)
JNKVV Res J 47(2): 202-204 (2013)

The estimated production function underlyingcrop-production enabled us to evaluate the efficiencyof prevalent factor proportions.
The MVP was computed by the multiplying thecoefficients of the given resource with ratio of thegeometric means of the output to the geometric meanof the given resource. For example, the MVP of Xi wouldbe, from the above production function the MVP of eachresource was worked out. The marginal productivity ofparticular input "Xi" at geometric mean of input andoutput expressed in following equation.
iMPVXi = bi Pxi
i
where,
i = gross value of output (Rs.)
i = Factor of production
bi = Regression coefficient of Xi
Pxi = Price of Xi
By comparing the respective input prices with theirmarginal values, fanners can decide as to whether theyshould increase or decrease the level of use of that,particular input of products.
Returns to Scale
The returns to scale could estimate from the type ofproduction function. Thus, returns to scale = a1 + a2 +…. + an
= ai =1, 2…….n
Therefore, the summation of the powers of allthe input variables provided us directly with a readyestimate of the returns to scale as also the degree ofhomogeneity of the production function. The returns toscale are deceasing, constant or increasing, Dependingon whether a, is less than, equal to or greater than one.
Results and discussion
Without having the functional analysis and estimatingthe marginal value productivity (MVPs) the existing
levels of inputs, one cannot come to the conclusion thatwhether the input is being overused or underused inproduction and also the contribution of differentresources in the production of crop. For this purpose,as mention earlier, the Cobb-Douglas type of productionfunction was fitted to the data and the estimateselasticity's of different inputs are obtained (Table 1).
Table 1. Coefficient of different resource use in chickpea Production
Input Coefficient
Constant 7.76Seed rate 0.21**Fertilizer and manure 1.34Plant protections measures 1.02Irrigation charges 1.85Human labour 0.05*Machine labour 0.16**R2 0.73**Returns to Scale 0.49**Significant at 1 per cent level*Significant at 5 per cent level
Seed rate, fertilizers and manures, plantprotection, irrigation facilities, human labour andmachine labour had the elasticity of 0.21, 1.34, 1.02,1.85, 0.05 and 0.16 respectively and were statisticallysignificant (Table 1). This means that one per centincrease in investment on these resources wouldcontribute that percentage increase in chick pea yield.The values of the elasticity's of these variables revealfurther scope for utilization of these inputs. The returnto scale was less than unity (0.49) indicating decreasingreturns to scale. The coefficient of determination (R2)provides an idea about the proportion of the totalvariation in yield explained by the selected variables.For chick pea crop the value of R2 was 0.73 this hasindicated that the selected variables contribute to theextent of 73 per cent of the total variation in grossreturns.
Geometric mean level and Marginal Value Product(MVP)
The result of production function analysis in terms ofGeometric mean level and Marginal Value Product arepresented in Table 2. It was conducted that the MVPs of
204
the seed rate, fertilizer and manure and plant protectionsimplies the profitable economic returns on investmentson these resources. The economic efficiency of selectedchick pea growers was 74 per cent. It reveals that thereis a considerable scope to increase the productivity.The average allocative efficiency of the selected chickpea growers was 90 percent. The study implied thatthe output of average farmers could be increased byadopting the allocation of resources fallowed by the bestpracticed farmers.

Abstract
An Investigation was undertaken to determine theadoption of Integrated Pest management practices of potatocultivation among 120 growers in Chhindwara district ofMadhya Pradesh. The data reveal that majority of potatogrowers had lower awareness for adoption of IPM practices.Education, annual income, area under potato crop, farmpower, social participation, information sources utilization,extension participation, mass media exposure, economicmotivation, attitude towards IPM, scientific orientation andknowledge level had significant association with adoption ofIPM practices by the potato growers under the study.
Keywords: IPM potato
Potato (Solanum tuberosum L.) is one of the mostpopular vegetable grown in M.P. because of its highernutritive and higher production.
Madhya Pradesh is one of the eight largest potatoproducer states in India having an area of 56695 ha.witha productivity of potato in about 125.76 q/ha. It isrecorded from the available secondary data that the areaand production of potato crop in Chhindwara district is6750 ha and 168750 metric tones, The Chhindwarablock shares an area of 2015 ha with a production ofabout 50375 metric tones.
The investigation was undertaken with thefollowing specific objectives to know the attributes ofpotato growers and the extent of adoption of IntegratedPest Management practices by potato growers and tofind out the association between adoption of IntegratedPest Management practices with the attributes of potatogrowers.

Methodology
The study was conducted in Chhindwara district ofMadhya Pradesh. There are 11 blocks in the districtsand out of them one block i.e. Chhindwara block wasselected purposively for this study because of largestarea under potato crop.
The respondents were selected through multi-step random sampling method. At first stage, out of131 villages of Chhindwara block, 6 villages wereselected randomly. At the second stage, a list of farmerswas prepared from all 6 villages. At third stage, 20 potatogrowers from each selected villages were randomlyselected from the list, making the total of 120 farmersfor the study.
Results and discussion
Higher percentage of the farmers (47.50%) were inmedium age group, maximum number of potato growers(35.00%) (Table 1). Out of total sample respondents,68.34 per cent were having less area under potato cropand majority of potato growers (58.34%) had low annualincome of Rs. 2,00,000/-. The higher percentage ofpotato growers had medium farm power and hadmedium social participation. About 50.00 per cent potatogrowers used medium information source and medium(49.16 %) extension participation. The higherpercentage of respondents (42.50%) had medium massmedia exposure and had higher (48.35%) economicmotivation, while 489.33 per cent had moderate attitude

Abstract
The growth pattern of chickpea production in different agro-climatic zones of Madhya Pradesh was examining using timeseries data for the period of last 40 years (1969-70 to 2008-09). To ascertain the change over the period was sub dividedinto two periods i.e. period-I (1969-70 to 1988-89), period-II(1989-90 to 2008-09) and overall period -III (1969-70 to 2008-09). The data shows that during period-I, growth in acreageand production of chickpea were positive and highly significantin Malwa plateau, Vindhyan plateau, Central Narmada valleyand Bundelkhand region. During period -II, these growths werepositive and highly significant of Vindhyan plateau, Satpuraplateau, and Kaymore plateau and it significant in State as awhole. During last 40 years, growth in area and production ofchickpea was found positive and highly significant in Malwaplateau, Vindhyan plateau, Central Narmada valley, Kaymoreplateau, Bundelkhand region and Nimar valley . State as awhole is also positive and highly significant during the studyperiod. During period -I, The positive and highly significantgrowth of productivity was shown in only Malwa plateau andBundelkhand region. In period- II, Only two regions viz., CentralNarmada valley Satpura plateau was shown positive andsignificant growth of productivity. It was found positive andhighly significant in the entire region except in Jhabua hillsand Northern hills region of Chhattigarh in period-III. Projectionof chickpea production for 2024-25 shows that the productionis likely to increase by 18.19 per cent and this may happendue to 14.46 per cent increase in yield and about 13.61 percent increase in acreage.

chickpea is grown in the Rabi season and its sowingtakes place during October-December. Chickpea is themost important pulse crop grown in India accountingfor 40% of the total pulses crop. This makes India theleading chickpea producing country in the world. InIndia, it is mainly used to produce 'dal' and besan(ground flour). The area and production of chickpea was2614.8 thousand hectare and 2841.60 thousand tonnesrespectively with average productivity of 1086.93 kg perhectare in Madhya Pradesh (2010-11). The productionof chickpea has remained almost same for the last 10years due to stagnant area and yield on account of shiftin cultivation from pulses to cereals and vegetables.The present study was undertaken to determine thevariability and growth of this particular crop in thedifferent agro-climatic zones of Madhya Pradesh. Thestudy focused on the pigeonpea of relative change,variability, and linear as well as compound growth inarea, production and productivity of Chickpea. Anattempt is made to project acrea, production and yieldof the crop for the year 2024-25.
Materials and methods
The study was confined all the 11 agro-climatic zonesof Madhya Pradesh viz. Malwa plateau, Vindhyanplateau, Central Narmada valley, Satpura plateau,Jhabua hills, Gird region, Kaymore plateau,Bundelkhand zone, Nimar valley, Northern hills regionof Chhattigarh and Chhattisgarh plain. The district wisetime series secondary data on area, production andproductivity pertains to last 40 years from 1969-70 to2008-09 were collected from various issues of "MadhyaPradesh Agricultural Statistics" published by the
210
Directorate of Farmer Welfare and AgriculturalDevelopment, Madhya Pradesh, Bhopal andCommission of Land Record Gwalior. The total periodof the study was divided into three sub period viz. period- I (1969-70 to 1988-89), period - II (1989-90 to 2008-09 ) and period III as a overall period (1969-70 to 2008-09). The relative change, coefficient of variation,standard deviation, linear growth rate as well ascompound growth rate was worked out for theinterpretation of results.
from 1510.63 in 1969-70 to 2011.50 thousand in 1988-89 with annual variation of 13.02 per cent in the State.The maximum relative change in the area was noted toCentral Narmada valley (36.70%) followed by Satpuraplateau (36.16%), Bundelkhand zone (34.40%), Malwaplateau (24.34%), Vindhyan plateau (11.81%), Girdregion (11.26%), Nimar valley (10.98%), Kaymoreplateau (3.38%) and Chhattisgarh plains (1.83%) in theperiod. The negative relative change in area wasobserved in Jhabua hill, Northern region of Chhattigarh

The projections of area, production and productivity for the year 2024-25 were worked out. The linear model wasused to project the area, production and productivity of chickpea
Results and discussion
The relative change, coefficient of variation, linear aswell as compound growth rate of area of chickpea indifferent agro-climatic zones of the State were workedout and presented as under sub heads.
Variability and Growth in Area
The maximum area of chickpea crop was confined toVindhyan plateau (31.35 %.) followed by Malwa plateau(25.86%), Kaymore plateau (15.37%), Central NarmadaValley (8.41%), Gird region (7.89%), Satpura Plateau(2.48%) (Table 2). These 6 agro-climatic regionscontribute about 90 per cent area of total chickpea areaof the State. The area of chickpea in the state increased
during the period -I. The Satpura plateau showsmaximum and positive significant growth as a linear(2.08%) and compound (1.87%) growth rate per annumin acreage of chickpea. The Jhabua hills, Kaymoreplateau Northern Hill region of Chhattisgarh andChhattisgarh plains are showing negative growth ratein acreage of chickpea revealing that this crop wasreplaced by wheat due to increase in irrigation potential.
In the period II, the area of chickpea increasedfrom 2061.00 thousand hectare in 1989-90 to 2564.93thousand hectare in 2008-09 with absolute change of503.93 thousand hectare in the state. The State isshowing of 24.45 per cent relative change, variation of9.73 per cent, linear and compound growth rate of 1.09and 1.13 per cent respectively. Amongst all the agro-climatic zones, the Vindhyan plateau was confined to

In period III, the acreage of chickpea has beenincreased from 1509.73 thousand hectare to 2564.93thousand hectare in the State while, absolute changeof Madhya Pradesh of 1055.20 thousand hectare aboutnearly 69.89 per cent relative change. The significantgrowth of chickpea acreage was noticed in period -III.The area of chickpea increased in the Malwa plateau,Vindhyan plateau, Central Narmada valley, Jhabua hills,Kaymore plateau, Bundelkhand zone and Nimar valleyand Chhattisgarh plains whereas decreased in Satpuraplateau, Gird region and Northern hill region ofChhattisgarh. The maximum relative change in area ofchickpea was noted in Vindhyan plateau (245.64%).The highest and significant compound growth as wellas linear growth rate in acreage was confined toVindhyan plateau (2.32%, 3.09%). The negative growthrate was observed in Satpura plateau, Gird region andNorthern hill region of Chhattisgarh in the state.
Variability and Growth in Production
The production of chickpea of 897.44 thousand toneshas increased 2304.73 thousand tones in MadhyaPradesh from 1969-70 to 2008-09. The production ofchickpea was highest in period -II as compared to period-I but growth rate was found highest in period -I ascompared to period -II (Table 3).
The Maximum relative change of chickpeaproduction was noted in Central Narmada valley(151.60%), followed by Malwa plateau (123.22%),Vindhyan plateau (105.52%) and decreased inproduction of chickpea shows in Satpura plateau,Jhabua hills, Kaymore plateau, and Chhattisgarh plainsduring period-I. The data on variability and growth ofproduction in different periods shows that the chickpeaproduction was increased from 897.74 thousand tones(base year) to 2304.73 thousand tons (current year),which showed absolute change of 1407 thousand tones(156.81 %) with variation of 27.32 per cent.
The production of chickpea increasedsignificantly growth of 2.72 per cent as a linear and 3.20per cent as a compound in Madhya Pradesh period I.The highest and significant compound growth ofchickpea production was noted in Malwa plateau
(5.23%). The negative growth rate in production ofchickpea was noted in Satpura plateau, Jhabua hills,Kaymore plateau, Northern hill region of Chhattisgarhduring period-I.
Amongst different region of State, the productionof chickpea increased from 1569.41 to 2304.73thousand tones with 46.85 per cent relative changeduring period-II. In period -II, the significant growth ratewas noted in period- II. Amongst all the agro-climaticzones of Madhya Pradesh, the Vindhyan plateau showsmaximum (120.49%) relative change in production ofchickpea.

Malwa plateau (13.02%) and Nimar valley (11.45%).The significant and positive linear growth of chickpeaproductivity was found in Malwa plateau (1.24%) andBundelkhand region (2.42%) during period I. (table 4)
In period-II, it is observed that the productivity ofchickpea was increased from 760.02Kg/ha in 1988-89to 897.51Kg/ha in 2008-09 which was about 18.09percent change in the state. The maximum relativechange in productivity of chickpea was noted in Satpuraplateau about 34.61 per cent followed by CentralNarmada valley, Vindhyan plateau, Gird region, Nimarvalley, Malwa plateau, Chhattisgarh plains anddecreased in Jhabua hills, Bundelkhand region,Northern hill region of Chhattisgarh in this period. Thepositive and significant growth in productivity ofchickpea was observed in Central Narmada valley andSatpura plateau at 5 per cent level. Only two regionsshow negative growth in productivity of chickpea duringperiod -II.
In overall period, the variability and growth ratein productivity of chickpea presented in the Table- 4 it isobserved from the data that the productivity of chickpeaincreased from 592.61 kg/ha to 897.51 kg/ha in the stateduring entire period with relative change and variationof 51.45 per cent and 17.69 per cent, respectively. Theproduction of chickpea shows significant growth of 1.24per cent (linear) and 1.47 per cent (compound) perannum in the Madhya Pradesh. The Central valleyshows the maximum relative change (114.34%) and
Jhabua hill shows the minimum (3.21%). The highestvariability in productivity of chickpea was observed inSatpura plateau (25.62%), followed by Central Narmadavalley (24.15%), Northern hill region of Chhattisgarh(23.85%), Bundelkhand zone (22.36%), Jhabua hill(21.41%), Gird region (20.36%), Bastar plateau(20.24%), Vindhyan plateau (19.15%), Kaymore plateau(18.91%), Malwa plateau (18.71%), Nimar valley(18.11%). The Malwa plateau, Vindhyan plateau,Central Narmada valley, Satpura plateau, Gird regionKaymore plateau, Bundelkhand region, Nimar valleyand Chhattisgarh plains were shows significant growthin productivity of chickpea during entire period.
With the present level of technological changeand govt. policies the area of chickpea will increasedfrom 2705.8 to 3074.18 thousand hectare in the year2024-25. The production will also increased from2638.80 to 3119.06 thousand tones and the productivitymay be increased up to 1116 from 975 kg/ha (2008-09)in the Madhya Pradesh. The chickpea acreage willincreased in the entire agro-climatic zones expectSatpura plateau, Northern hill region of Chhattisgarhand Chhattisgarh plains (Table 5).
The zone wise analysis of projection shows thatacreage of chickpea will likely to increase in almost allthe agro-climatic zone except Satpura plateau, Northernhill region of Chhattisgarh and Chhattisgarh plains.Similar trend was observed for likely change inproduction by the year 2024-25.

Abstract
The study comprises the information collected throughsecondary data (1990-2009) of all the districts of MadhyaPradesh and primary data collected from 150 fodder growersby personal interview from three maximum fodder producingdistricts (Rajgarh, Shajapur and Ujjain). It is observed fromthe study that the fodder cultivation was not shown too muchprogress in the state since 1990. The cultivators still growingfodder in the line of crop cultivation and the majority of themwere not known the recommendation package of practices offodder cultivation. The fodder growers were also found notdoing fodder preservation technique viz. hay and silage makingfor the lean period. They were not cultivating fodder in thecommercial line as none of them involved in marketing offodder in the state. Hence, it is the right time that stategovernment re-intensified their efforts in progress of fodderin the state because without introducing dairy based farmingsystem approach on the farmers' farm, their income shouldnot become double, which is the ultimate target of the stategovernment. It is only activity which not only generated incomebut also enhanced employment at their owned farm.

Madhya Pradesh is basically an agricultural state whereabout 70 per cent of its peoples live in villages. Theirlivelihood is dependent mainly on agriculture and animalhusbandry. Though, state has a huge livestockpopulation of over 4162.96 millions, besides poultry,yet the production of milk and other livestock productsis the lowest in India. The state, highly deficient invarious cattle products, though state has about one-fourth of the total cattle population of India. As againstthe minimum nutritional requirement of 201 g/head/dayof milk set by the nutritionists, 100 g/head/day is theavailability per head in the state. One of the mainreasons for the low productivity of livestock is

malnutrition and the low genetic potential of the animals.In fact, the economic viability of livestock husbandrydepends on sources of feed and fodder as feeding costconstitutes about 65 - 70% of the total cost of livestockfarming. The feed given to cattle comprises dry fodder,green fodder and concentrates of which dry fodder formsthe major share. The adequate supply of feed and fodderis a critical factor affecting performance of animals. Thisfact is adequately supported by the figures of availability,vis-a-vis the requirement of green-fodder crops, cropresidues and concentrates, which shows that there is ahuge gap of between demand and supply of all kinds ofthese feeds and fodders in the state.
Fodder crops may be classified as temporary oras permanent crops; the former are cultivated andharvested like any other crop, the latter relate to landused permanently (five years or more) for herbaceousforage crops, either cultivated or growing wild (wildprairie or grazing land). They may include some areasof forest lands that are used for grazing. The foddercan be fed to animals through processing as green feed;as hay, i.e. crops harvested dry or left to dry if harvestedgreen; or as silage products (Kindu Mekonnen et al.2009) Though, Silage or ensilage is a method ofpreservation of green fodder through fermentation toretard spoiling and this method of processing is morepopular in India as compared to hay making but inMadhya Pradesh the hay and silage making methodsof preservation of fodder are not been found in practicesby the cultivators.
On the other hand, if we examine the landresources available for growing fodder and forage crops,it is estimated that the average cultivated area devotedto fodder production is only 4.4 per cent of the totalarea in India, and it was found to be only 3 per cent inMadhya Pradesh similarly, the area under permanent

pastures and cultivable wastelands is approximately 13and 15 million hectares respectively but it was found tobe only 4.42 and 3.37 per cent of net area sown ( 150.74lac ha) in the state likewise, the total area under forestsis 2.51 crore hectares and that open to grazing is 2.1crore hectares. All these resources are able to meetthe forage requirements of the grazing animals onlyduring the monsoon season. But for the remainingperiods of the year, the animals have to be maintainedon the crop residues or straws of sorghum, pearl millet,ragi, wheat, barley, etc. either in the form of whole strawor a bhusa, supplemented with some green fodder, oras sole feed. The crop residues are available mainlyfrom wheat, paddy, pearl millet, sorghum, soybean,sugarcane trash, etc., which are poor in nutritive value.Cultivation of high yielding or hybrid varieties of wheatand paddy to enhance grain production has changedthe grain-foliage ratio more favorable to humans, thusaffecting the production and availability of straw.Besides this, the decrease in paddy cultivation due todrought and water shortage has also affected theavailability of straw. The green fodder resources forlivestock are mainly derived from grazing in grasslandsand pastures, fodder crops from cropped lands, weeds,bund grasses, tree leaves and mixed forages. Thesustainability of dairy industry in India largely dependsupon the quality of herbage based animal feed andfodder. Green fodder is the essential component offeeding high yielding milch animals to obtain desiredlevel of milk production. Lack of quality fodder,especially during winter, is a major limiting factor inimproving livestock production. (Dost Muhammad 2001)The technology of growing year round fodder productionhas helped the farmers/dairy owners to sustain theirmilch animals of 6-7 liters per day potential withminimum use of concentrates, thus producing milk atcheaper cost.
The cost production of milk increased day by dayand in the production cost of milk, the cost of greenfodder is found highest. If the cost of production of greenfodder decreases it also decreases the cost of milkproduction Hence, looking to the above points inconsideration present study is formulated to examinethe status, the costs and returns of various fodder cropsand problem faced by the growers in production offodder in Madhya Pradesh.
Research Methodology
Amongst different districts (50), 3 districts i.e. Rajgarh,Shajapur, and Ujjain have been selected purposivelyfor the study on the basis of the highest area in fodder
cultivation in Madhya Pradesh (569987 ha). Amongstthe selected districts, two blocks from each district, oneblock near and one distant to the periphery of districtheadquarter has been selected randomly to realize theeffect of distance factor in the findings. A cluster of 3villages has been randomly chosen from each block.Finally, a sample of 25 farmers was selected randomlyfrom each selected cluster, spreading over various farmsize categories i.e., marginal (less than one hectare),small (1-2 hectares), semi-medium (2-4 hectares),medium (4-10 hectares) and large (more than 10hectares) based on the size of the operational holding,making a total sample of 150 farmers. The primary datacollections were done by the personal interview methodfor the reference year 2009-10.
The required secondary data were also collectedon the different aspects of the study from the all theinstitutions (Department of Farmers' Welfare andAgricultural Development, Vindhyachal Bhawan,Bhopal, M.P; Department of Animal Husbandry,Kamdhenu Bhawan, Bhopal, Madhya Pradesh;Department of Agril. Statistics Government of MadhyaPradesh, Bhopal) from their published and unpublishedrecords. The primary data were classified and tabulatedin light of stated objectives of the study. The SPSS(Statistical Package for Social Science) was used forclassification, analysis and tabulation of collected data.
Results and discussion
The status of fodder in Madhya Pradesh, cost andprofitability of fodder and problem faced by the foddergrowers are the basic areas of the study.
Status of Fodder
Fodder cultivation is found to be in a nascent stage inMadhya Pradesh. The cultivators of Madhya Pradeshdevoted only their 3 per cent of gross cropped areaunder fodder. (Fig. 1) Out of the total fodder area (0.74lakh ha), the cultivators of Madhya Pradesh devotedtheir maximum area under the cultivation of pearl millet(20%) followed by Sorghum (4%), Berseem (2%) andMaize (1%). The 72% of the fodder area is found to becovered under unidentified other fodder crops. Although, the pearl millet which was highly cultivated bythe cultivators, but it was found to be mainly cultivatedfor grain purposes rather than fodder. The by productof this crops is used as a fodder for the live stock.

Thus, sorghum, berseem and maize were foundto be major fodder crops in the state (Fig 2). An averagefodder grower of the Madhya Pradesh devoted their 1 -2 Bigha (0.2-0.4 ha) area of cultivated land in theproduction of fodders in all the seasons of the year.
The area of fodder was found to be declined overthe years from 974888 ha. (1990-94) to 745285 (2006-09) in Madhya Pradesh during the last 20 years (Fig.3). The area of sorghum, berseem, loosarn, jai werefound to be increased over the year 1990-94, while thearea under guar and other fodder decreased in MadhyaPradesh (Table 1).
As regards to the growth of these are concernedin Madhya Pradesh, the areas of all the fodder cropswere found to be decrease by 1.97% per year duringthe last 20 years. The growth of these fodders was foundto be more in the period I (2.52%/year) as compared toperiod II (-2.40%/year). Among the different fodder cropsthe highest growth of fodder was observed in the areaof loosarn (4.98%/year) followed by berseem (3.89%/
year), sorghum (2.79%/year), Jai (2.39%/year) andmaize (1.99%/year) during the last 20 years in MadhyaPradesh (Table 2).
Cost of Cultivation
The cost of cultivation incurred in cultivation of majorcrops viz. maize (rainy season), berseem (winterseason) and sorghum (summer season) by the foddergrowers of different size of farm are analysed tocompared the profitability of crops and find out the shareof different inputs in the total cost cultivation and seemsthat maize is found to be a major fodder crop cultivatedby the majority of fodder growers in the rainy season.
The comparative picture of cost of cultivation (Rs./ha) of maize fodder in different size of farms wasanalyzed and observed that an average fodder growerinvested Rs. 9264.64 /ha in the cultivation of maize andas the size of farm increased from marginal (Rs.7782.15/

Problems faced by the fodder growers
The various problem which faced by the fodder growerin the cultivation and preservation of fodder arepresented (Table 7) and observed that none of thesample fodder grower done preservation practices forpreservation of fodder for lean period. Lack of technicalknow how (76.66%) was found to be the biggest problemobserved during the course of investigation and reportedby the maximum numbers of respondents in the areaunder study.
The inferior quality of seed (74.00%), faulty inputdelivery system (74.00%), high expenditure inproduction due power cuts (74.00%), non availabilityof skilled labour in time and high cost of labour (68.00%),faulty government policy as distribution of mini kits offodder seeds from veterinary department instead ofagriculture department (52%) were the other majorproblems found in the study area reported by themajority of the respondents. The similar findings alsoobserved by Dost Muhammad (2001).
Hence, it is clear that the fodder cultivation hasnot shown too much progress in the state since 1990although it is found profitable in the state. The cultivatorsstill growing fodder in the line of crop cultivation andthe majority of them were not known the recommendedpackage of practices of fodder cultivation. The foddergrowers were also found to be not done fodderpreservation techniques viz. hay and silage making forthe lean period. They were not found cultivating fodderin commercial line as none of them involved in marketingof fodder in the state. Hence, it is the right time thatstate government re-intensified their efforts in progressof fodder in the state because without introducing dairybased faming system approach at the farmers' farms,their income should not became double, which is theultimate target of the state government. It is only systemof farming which was done by the farmers since longtime. It not only generated income but also enhancedemployment at their owned farm. The mini kit of foddercrops were found to be distributed by the animal
husbandry department and they were not taking interestin the extension activities concern to the fodder, due tolack of training. It also lacks the aura of being doctorand the fodder is more inclined towards agriculture. Theanimal husbandry department in the state is onlyconcerned with the treatment aspect and improvementof breeds because here lays the money. Investinginterest in fodder sector will benefit the live stock ownersbut who cares? Hence, there is urgent need to createthe a separate department for fodder developmentseparate from animal husbandry department or mergethe fodder development sector in agriculture departmentfor better extension activities and distribution of foddermin kits with technical know-how because the cultivationof fodder is more or less similar to the cultivation ofcrops.

Abstract
Rice -wheat is a major cropping system followed in Jabalpur,Rewa and Shahdol division of Madhya Pradesh andtransplanted rice is a common practice of rice cultivation. Thetransplanted rice has dependency on labour and water. Thispractice is labour intensive and required huge amount of water,which is a crucial input now a day. The delay transplanting ofrice due to non-availability of labourers at the peak time causesdrastic reduction of crop yield and also vacated the field quitlate due to which the sowing of subsequent rabi crop is alsoget delayed. The direct seeding of rice in upland conditionposes the sevier problem of weed infestation. Keeping in viewthese factors into account the study was conducted underOFT (On Farm Trail) to field evaluated the manually operated8-row paddy drum seeder for planting of sprouted paddy seedsunder puddle soil in comparison to conventional practice ofrice cultivation i.e. transplanted rice on farmers fields over anarea of 2 ha in Shahdol district of Madhya Pradesh. The studyrevealed that the paddy drum seeder gave an average workoutput of about 0.8 ha per day (8 hrs working) at an operatingspeed of 1.00 kmph. The seeder dropped 2-3 seeds per hillat a spacing of 12 cm in rows 20 cm apart with an averageseed rate of 30.05 kg/ha. It has been also observed thatseeding of rice with drum seeder gave huge labour saving ofabout 86% in comparison to transplanted rice. The crop yieldobtained was 34.9% more in case of paddy drum seeder.The paddy drum seeder also found cost effective as it incurredonly Rs 750 per ha which was about 80.26% less incomparison to transplanted rice in which it was Rs 3800 perha.

and is grown between latitudes 450 N and 400 S(Mohanty et al. 2008). Ravishankar et al. (2006) alsoreported that under conventional method of planting,the seed rate ranged from 44 to 55 kg/ha with mean of48 kg.
In Jabalpur and Shahdol division of MadhyaPradesh more than 80% rice cultivation is done bytransplanting method and remaining area is under directseeding (broadcasting method) due to lack of wateravailability, undulated topography and labourunavailability. Direct paddy drum seeder is a small handoperated farm implement is used for direct paddyseeding. The activity of the transplanting seedlings inpuddled fields carried out consists of bending and staticposture for long duration of time leading to manyoccupational hazards (Singh and Tiwari 2009).Transplanting of rice in puddled fields is generallypreferred over dry sowing of seeds due to severeproblem of weeds. The raising of nursery and manualtransplanting are both labour intensive and costlyprepositions (Das 2003).
It is very efficient machine developed by TamilNadu Agricultural University. In this study direct paddydrum seeder was tested at 2.0 ha area of five farmer'sto evaluated the capacity of the machine, yield of thepaddy crop and economics of the direct paddy sowingunder on farm trail programme.
Material and methods
The study was carried out at Shahdol district of MadhyaPradesh, with 2 ha land of 5 farmers (0.4 ha eachfarmer), which are involved in rice cultivation and

remaining 2 ha land of 5 farmers used rice seeding bybroadcasting method were selected as control. The fieldexperiment was conducted in the month of July-October.On farm trials were sown with paddy variety i.e. IR 36through paddy drum seeder as well as in broadcastingmethod. During the experiment various parameters viz.,field capacity of paddy drum seeder, seed rate and yieldwere studied.
The machine
Direct paddy drum seeder is used for sowing germinatedpaddy seed directly in wetland field. There is no needfor transplantation. It is a manually pulled implement. Itcovers 8 rows of 20 cm row-to-row spacing at a time. Itis made up of plastic materials. The shaft and handleare MS steel material. There is a Hyperboloid shapedseed drum with 200mm diameter and 9 numbers of seedmetering holes of 9 mm hole diameter (Table 1). Bafflesare provided inside the seed drum between seed holesresulting in uniformity of seed rate throughout theoperation. These baffles also ensure hill dropping of
seeds. Each seed drum has two rows of planting. Foursuch drums can be assembled to form 8 rows of seeddrum as shown in the picture.
Wheels are provided at both ends. These wheelsare made up of plastic material to provide floatingcharacteristics. Wheels diameter is 2 feet. One squareshaft, handle base and handle, four seed drums areassembled together with the square shaft. The handleif meant to pull along.
Field preparation
In the study area well puddled and levelled fields wereprepared. Water was drained out at least 24 hrs forbefore sowing to form hard slurry pan of the puddledsoil. At the time of sowing only paper thin of water shouldbe maintained in the puddled field. Only just sproutedseed packed with gunny bags should be used. Waterwas flooded to the puddled once in three days aftersowing and drain out immediately. This practice shouldcontinue for 12 days. Thereafter depending upon the

height of the seedlings water was allowed to stand inthe field. All farmers field were well prepared in themonth of May before rainy season. As per agronomicalrecommendation FYM (Farm Yard Manure) and NPK(Urea, DAP and Kcl) were applied to all the fields. Tocontrolling the weeds problem cono weeder and manualpractice were adopted. In non rainy days life savingirrigation was applied through open and tube well.Puddling was well prepared and levelled. Water wasdrained out before 24 hrs. Before sowing to form hardslurry pan of the puddle soil. At the time of sowing onlypaper thin of water was maintained in the puddled field.Only just sprouted seeds packed with gunny bags were
used. Irrigation water was flooded to the puddled fieldonce in three days after sowing and drains out sometime immediately.
Result and discussion
It was observed that average field capacity of the paddydrum seeder was 1.042 ha/day (Table 2) and in case ofbroadcasting method less time is required for sowingbut uniformity/plant geometry was not maintained. Seedrate has reduced to 39.9 % as compared to broadcastingmethod. It was observed that weed control in line sowingis easily manageable. Data is also the BC ratio hasincrease 22.47% (Table 2).
Manually Broadcasting
The paddy drum seeder was found a suitable handoperated tool in paddy cultivation was irrigation andlabour is the major problem. It is light in weight andeasily handled. It reduces the seed rate and maintainsuniformity in seed sowing and plant population. Labourcost is reduced drastically.
OFT has proved its value as a methodology to afford atechnology for the farmers. The present study resultedin demonstration and extension of drum seeder as adrudgery reducing tool or technology in local farmingcommunities. Use of drum seeder helps in timely sowingof crop resulting in more yield. Sowing by drum seedersaves costly seeds. The drum seeder reduces labourrequirement and cost of sowing. Line sowing by drumseeder reduces weeding cost due to use of mechanicalwelders with transplanting. The crop matures one week

Abstract
The policy maker can either attempt to enhance the uptake ofimportant technologies relevant particularly to the small scaleagricultural production by improving research anddevelopment process or they can take steps, which enablesthe farmers to improve technical efficiency in production, whilethe farmer probably require a long time, considerable fundsand efforts but are likely to yield long run benefit. Else, raisingtechnical efficiency offers more immediate goals at modestcrops. If it can be shown that substantial inefficiencies arepresent in Agricultural production. Such research efforts arebased on an analysis of technical inefficiencies in productionof wheat crop by farmers. So an attempt has been made inpresent study to investigate farm specific technical efficiencyfor wheat crop in Jabalpur District of Madhya Pradesh. Theaims of present study are to evaluate efficiency of a particularfarm and to observe up to what extent its efficiency can beincreased without adding any additional resources. The resultsshows a comparison of the small, medium and large farmersvariability and technical efficiency is less in medium and lesserin small farmers and large in large farmers. Mean technicalefficiency is high in large farmer compared medium and smallfarmers.

Wheat is a major cereal crop in India. India producedabout 70 million tones of wheat per year or about 12%of world production. India is the second largest producerof wheat in the world and also second largest in wheatconsumption after china. The efficiency of productionis extremely important for output growth: using existingresources in the best possible manner would yield thehighest possible output for the given technicalconstraints. The efficiency of a farm /production unitcan be measured in terms of allocative efficiency andtechnical efficiency. Technical efficiency is the ratiobetween actual and potential output of a production unit.

The result of this study is useful for policy makersto rationalize the development policies for a particularcrop in region. Farrell (1957) defined the ratio, OB/OA,to be the technical efficiency of the firm with input-per-unit-of-output values at point A. Farrel (1957),suggested that the efficient unit isoquant be estimatedby programming methods such that the convex functioninvolved was never any of the observed input- per-unit-of-output ratios. Kebede (2001) examined technicalefficiency of rice farmers in mid hills of Nepal by usinga half normal stochastic frontier model. The averagetechnical efficiency of paddy farmers was estimated at71%. It was found that the farmers with poor quality ofland were technically more efficient. It was concludedthat farming experience and education were bothsignificant variables for improving technical efficiency.Baksh (2007) used a stochastic frontier productionfunction incorporating technical inefficiency effect modelto estimate technical efficiency and profitability ofgrowing vegetable in Punjab. Four vegetables namelypotato, carrot, radish and bitter gourd were selected forstudy. Results of the study showed that the mean levelof technical efficiency was 82% in case of radish, 72%in case of carrot, 70 % in case of potato and 66% incase of bitter gourd. It was observed that with anincrease in age of the vegetable growers, level oftechnical efficiency declined except in potato production.Education level and access to extension services werepositively related to the level of technical efficiency incultivation of all vegetables. The most profitablevegetable was bitter gourd followed by carrot, potatoand reddish.
Methodology
In Madhya Pradesh, Jabalpur district were chosen forthe study, taking in to consideration the sample growerswere further classified in to three classes based on thefarmers as class-I, Large farmers, class-II, medium

farmers and class-III, small farmers. Multistage stratifiedrandom sampling was adopted to collect the data fromthe farmer. The first stage unit is village second stageunit is farmers which were grouped into three stratasmall medium and large farmers according to size ofland holding. From each group sample has been takenproportional to size of strata.
The data was collected from the farmers throughpersonal interview method using well-structured andpre-tested interview schedules. The major input forwhich the costs were worked out includes seeds, labour,plant protection, fertilizer, manures etc. the collecteddata was analyzed in order to estimate costs and returnand to work out the technical efficiency. The data wascollected from the wheat grower farm of the Jabalpurdistrict, taken purposively selected farmer of 2011-12.Sample size consists of 60 wheat growers.
Measurement of Technical Efficiency
The present study uses the stochastic frontierproduction function approach to measure the technicalefficiency in wheat production. Suppose that a farm hasa production plan (Y0, X0), where the first argument isthe set of outputs and the second represents the set ofinputs. Given a production function f(.), the farm istechnically efficient if Y0=f(X0) and technical inefficientif Y0< f(X0). Therefore, the TE can be measured by theratio
0 Y0/ f(X0) 1
The actual production function can be written as:
Qi = f (Xi, ) exp (-ui) and 0<ui< ; i=1,2,..n…….… (1)
Where Qi represents the actual output for the ith sample(production) unit; Xi is a vector of inputs and is a vectorof technology parameters to be estimated; f(.) is thefrontier production function and ui is a one -sidedresidual term. If the production unit is inefficient, itsactual output is less than the potential output. Therefore,we can treat the ratio of the actual output Qi and thepotential output f(.) as a measure of the technicalefficiency of the technical efficiency of the productionunit.
Using equation (1) above, we can write this measureas:
TE= Qi/f (Xi; ) = exp (-ui)…….…………..…. (2)
ui is zero if the production unit produces the potentialoutput and less than zero when production is below thefrontier. A random noise variable Vi can be included inthe equation (1) to capture the effect of other omittedvariables that can influence the output as:
Qi= f(Xi; ) exp(vi-ui)…………..….(3)
This new function is known as the individual-specificstochastic production frontier function. The likelihoodfunction for this model is:
L=-N ln - constant + [ln (- i / ) - ½ ( i/ )2]……(4)
Where, = u/ v, 2 = v2+ u2, and is the cumulativestandard normal distribution function and i = (vi-ui); uand v are standard deviations of the residuals u and vrespectively. The maximum likelihood estimation (MLE)method can provide the estimates of the stochasticfrontier production equation. Our stochastic frontierproduction function is given by:
ln Qi= 0+ L ln L + A ln A + F lnF + vi-ui ………(5)
Econometric Models
Production frontier models are reviewed in three sub-sections involving deterministic frontiers, stochasticfrontiers and panel data models. For convenience ofexposition, these models are presented such that thedependent variable is the original output of theproduction process.
Deterministic frontiers
The deterministic frontier model is defined by
Yi= f(xi/ ) exp (-Ui), i=1,2,3……….N……………(1)
Where Yi represents the possible production level forthe ith sample firm; f(xi/ ) is a suitable function of thevector, xi, of inputs for the ith firm and a vector of
230
unknown parameters; ui is a non-negative randomvariable associated with firm- specific factors whichcontributed to the ith firm not attaining max imumefficiency of production; and N represents the numberof firms involved in a cross-sectional survey of theindustry. The presence of the non-negative randomvariable, Ui, in model (1), defines the nature of technicalinefficiency of the firm and implies that the randomvariable, exp -Ui), has values between zero and one.Thus it follows that the possible production, Y i, isbounded above by the non-stochastic (i.e.,deterministic) quantity. The inequality relationships,
Yi f(xi, ), i=123 i=1, 2, 3…….N……………(2)
The technical efficiency of a given firm is definedto be the factor by which the level of production for thefirm is less than its frontier output. Given thedeterministic frontier model (i), the frontier output forthe ith firm is Yi* = f (xi, ) and so the technical efficiencyfor the ith firm, denoted by TEi, is
TEi = Yi/Yi*
= f (xi, ) exp (-Ui)/ f (xi, )
= exp (-Ui) ……………….………... (3)
Stochastic frontiers
The stochastic frontier production function is definedby
Yi = f(xi, ) exp (Vi -Ui) i=1, 2, 3…….N…………(4)
Where Vi is a random error having zero mean, which isassociated with random factors not under control of thefirm.
Panel Data Models
The deterministic and stochastic frontier productionfunction (1) and (4) are defined for cross- sectional data.If time-series observations are available for the firmsinvolved, then the data are referred to as panel data.Pitt and Lee (1981) considered the estimation of astochastic frontier production function associated withN firms over T time periods.
The model is defined by
Yit = f (xit; ) exp (Vit -Uit) i=1, 2, 3…….N
T=1, 2, 3…….T……………………..…(5)
Where Yit represents the possible production for the ithfirm at the tth time period.
For the present study, a Cobb-Douglasproduction function of the following form will bespecified.
ln Yi = 0+ 1i lnX1i+ 2i lnX2i+ 3i lnX3i+ 4i lnX4i+Vi - Ui
Where, Yi =yield (kg/farm), X1= Expenditure on seed(Rs/farm), X2= Expenditure on labour (Rs/farm),X3=Expenditure on fertilizer (Rs/farm), X4=Expenditureon irrigation (Rs/farm), i=vi-ui i=1,2,3………n farms
Result and discussion
In order to estimate the technical efficiency among thefarmers, the stochastic function of Cobb-Douglas formwas estimated using this method. The technicalefficiency of wheat was estimated using this method.The technical efficiency of wheat was estimated usinga frontier production function. The variables wereexpenditure on seed and fertilizers, expenditure onirrigation and labour expenses, and the dependentvariable as the yield of wheat.
Small Medium LargeN 20 20 20Mean of TE 0.69 0.77 0.84Minimum 0.61 0.71 0.75Maximum 0.77 0.86 0.93
The technical efficiency of small farmers whichvaries from 61% to 77% with mean 69% and mediumfarmers varies from 71% to 86% with mean 77%. Thetechnical efficiency of large farmers varies from 75% to93% with mean 84%. Thus we compare the smallmedium and large farmer's technical efficiency. Meantechnical efficiency is high in case of large farmers ascompare to medium and small farmers. Therefore it isconclude that large farmers are more technically efficient
231
than the medium and small farmers. The reason behindthis is the large farmers are educated and they havemore facility of agriculture implement and knowledgeso due to this their technical efficiency is high andmedium and small farmers are not as much as educatedas higher groups. So they have the lack of knowledgeand have less facility in comparison to large group.Therefore small wheat grower should be given with theexposer of technical knowledge by educating them,through training programme or demonstrated on theirfield. The medium farmers should also be given thetraining programme for the vertical growth in theproduction of wheat. The large farmers show hightechnical efficiency with the higher stability and thevariability in the small farmers are more in comparisonto medium and large farmers.

The above tables show the technical efficiencyof small medium and large farmers. For small farmersthe mean technical efficiency is 69%, medium farmershave the technical efficiency 77% and large farmershave the mean technical efficiency 84%.
The variability among the small farmer is highfollowed by medium and large farmers and technicalefficiency is high in large followed medium and smallfarmer. It means large farmers have more knowledgeabout the technology and they apply it since theirtechnology is stable in comparison to medium and small.So small and medium farmer need more training
232
regarding the technology generates and also requireeducation for the stability of technology. The data showsthat small and medium farmers are spending more manyin the seed, labour, fertilizer and irrigation but their returnare not as much as large farmers. It shows that thereare unfair for the latest knowledge of seed, optimumuse of labour, proper timely application of plantprotection and timely application of fertilizer andirrigation.
The study has indicated that wheat farmers inJabalpur district are substantial technical inefficient.Hence, the study indicates considerable potential forimproving productivity of the crop wit given level of input'use and technology. In addition, improving efficiencywill mean farmers gaining considerably in terms ofprofits. Inefficiencies could be attributed to non-farmemployment, education level, farm experience, degreeof specialization, etc. setting minimum education levelin primary schools for the long run result and increasingnumber of extension workers are other policy optionsto increase the technical efficiency.
There is therefore a substantial potential forenhancing profitability by reducing costs throughimproved efficiency. By operating at full technicalefficiency levels, on average, the sample producerswould be able to reduce their costs of production. Thispotential cost saving in production costs will translateinto enhanced profitability and additional income forwheat producers. Thus it can be said that the level ofeducation of the household head, number of extensionvisits, access to credit, and membership in a farmer'sassociation are significant variables for improving helevel of technical efficiency.
The positive impact of education on technicalefficiency will enhance the farmer's ability to receiveand understand information relating to new agriculturaltechnology. Since there might be limited opportunitiesof raising the level of education of farmer's in the shortterm, intensifying farmer training programmes throughvarious innovative and vocational education programsand extension delivery system would be more practical.In the medium-term, policies should be geared towardspromoting formal education as a means of enhancingefficiency in agricultural production.

Abstract
The aim of this study was to make a statistical analysis of thelinear models in soybean production and soybean oilproduction in Madhya Pradesh and India. The data set usedfor this analysis was taken from soybean processorassociation (SOPA) Indore. Following stochastic models weretaken: Linear, Quadratic, Compound, Cubic and Power. Formodel fitting performance, we used four comparison criteria;coefficient of determination (R2), sum of Squares error (SSE),root mean squares error (RMSE) and absolute prediction error(ARPE). The results indicated that Cubic, Quaderatic andPower models are more useful than other models to estimatesoybean production and soybean oil production in India andMadhya Pradesh.

Coefficient of determination
Residual variance
The parameters of the linear models wereestimated by ordinary least square method. Before fittingmodels, the whole data set related to each factor wasdivided in to two parts the first part for estimation of themodel and the remaining part for checking of its stability.Stability checking of a model enlightens on themagnitude of the strength of the forecasting model,derived by utilizing the first part of the strength of theforecasting model, derived by utilizing the first part ofthe data set, in predicting a future observation takenfrom the second part of the data set. This magnitude ismeasured by a "statistic'', called absolute predictionerror ARPE expressed in percentage
ARPE= { Est. - / } × 100
Where, = new observation from the second part ofdata set and Est. = estimated value of derived fromthe forecasting model.
The procedure was carried out with respect todata sets on production figures related to the factorsunder study. The first part of the data set in respect toeach factor was plotted in a scatted-diagram over timeand utilizing the theory and expertise a few good models
were identified. Beside the summary statistics, theparameters of these models were estimated by OLStechnique. By comparing and judging judiciously theestimates of the parameters, summary statistics, viz.coefficient of determination R2; residual mean squaresor error variance and ARPE values, fitted better modelswere screened primarily and these models wereupdated and tested for their adequacies with regard tothe error properties.
Then from among the best fitted adequate, aparsimonious model was selected for forecasting thefuture values of each factor. A best fitted parsimoniousmodel is one which has the smallest RMS with smallernumber of parameters in a set of competing best fittedadequate models. The 95% confidence interval wascomputed for the future value of each factor basing upon the updated forecasting models. This interval willensure the occurrence of this projected value in theinterval in 95 cases out of 100 cases.
Results and discussion
By judicious comparison among the models with respectto R2, RMS and ARPE values, the Quadratic, Cubic andPower models are screened to be the best fitting models.These model, also exhibited stability for predicting futurevalues in respect of each factor.
