Conclusion Reference

Introduction

The variation of climate may cause a great impact on the productivity of agriculture crops and thereby production in the region.

The regional variation in regional climate have direct impact on the regional economy especially in agrarian countries like India

In the recent year, priority is given to studies of climatic change/fluctuation. In fact agriculture and f trend to be well adjusted to the main climatic condition and slow little sensitivity to moderate variation around this means

. In view of this here an intensive analysis has been made for most important climate parameter in rain fed agriculture i.e. rainfall and potential evapotranspiration.

Objective

To analyze the trends and patterns of change in onset and offset of Monsoon and its effect on growing season of rain fed crops over the plateau region of Maharashtra.

Data base The records of precipitation and

potential evapotranspiration from year 1901-2008 has been collected from the web site www.indiawaterportal.org.in

Methodology

preparatory season (pre humid period). when precipitation(p) exceeds 0.5 of potential evapotranspiration (PET)

Onset of effective monsoon-when precipitation exceeds potential evapotranspiration

Growing season-from onset to offset of monsoon -humid period

Offset of monsoon-when 0.5 exceeds precipitation –harvesting period.

Methodology …cont

Calculated Day and Duration for › Day of Starting Pre Humid Period› Duration of Preparatory period › Day of Onset of effective monsoon› Duration of humid Period› Day of offset of effective monsoon› Duration of Harvesting Period › End of Harvesting Season (Post humid

Season)

Methodology …cont

Calculated Deviation of › Starting Pre Humid Period› Preparatory period › Onset of effective monsoon› Growing Season› offset of effective monsoon› Harvesting Period › End of Harvesting Season (Post humid

Season)

Methodology …cont

The results are shown by tables, isoline maps and graphs

The intensive study to analyze the annual change from 1990-2008 sample location are collected from each agro-climatic region of Maharashtra.

Study region – Maharashtra agro-climatic zones

WESTERN GHAT ZONE, TRANSITION ZONE -1, TRANSTION ZONE-2 , SCARCITY ZONE, ASSURED RAINFALL ZONE, MODERATE RAINFALL ZONE , EASTERN VIDARBHA ZONE

conclusion

In general western maharashtra,central marathvada experienes +-49 to 69days days of shifting.

Vidarbha expeerinces +-7 days of shifting.

Khandesh experinces +-7 days of shifting.

maximam change in growing season in assured and the drought prone area shows some about 60 years of cycles in general.
