System of Rice Intensification
System of Rice Intensification: Pabinhi Farmers’ Experience Rene Jaranilla, Dionito Eñano and Gerry Garingalao
Guimaras FactsLocated southeast of Panay island & northwest of Negros island in Western VisayasTopography generally gently sloping to rolling, with land elevation from 0-300m above sea levelDry season: Nov. to AprilWet season: May to Oct.
Population: 141,450Major agricultural products: palay (rice), coconut, mango, cashew, vegetables, citrus, camote, corn, cassava, legumes, livestock, poultry, and fishMajor industries: mining & quarrying, lime production, fruit processing, and tourism.
System of Rice IntensificationObjective: Increase rice production withouthaving to make any significant new
investment
Transplant very young seedlings (with 2 leaves)Plant individual seedlings, one by one spaciously, not in clumpsWeed the rice early and repeatedly (if possible with rotary weeder)Minimum use of water, and letting soil dry our periodically during first months
Key principles
NurseryPre-transplantTransplantWeedingWater management
S.R.I Basics: How and Why
Nursery
Pre-Germination Practices Soak seeds for 12-24 hrs in
water 35-40 degrees Celsius Second day -- place in a warm
place
Garden-Type Nursery Spread out sowing in nursery
over several days, to insure that very young seedlings are available during the whole transplanting period
Small and close to the farm (10 sq. m = 1000 sq. m)
Keep nursery soil moist, never floodedCover nursery with mulch during the first daysWater in morning and evening, never in full sun
Pre-transplant
Seedling should have just 2 leaves with the seed sac still attachedKeep seedling together with seed and some soil around its rootsUproot a few seedlings at a time, transporting right away to the field and plant seedlings no more than ½ hour laterThe less trauma, the better for the plant
Transplant
Transplant single seedlings -- not in clumps
Transplanting several seedlings in a clump makes the plants compete with each other for nourishment and light
Transplant the seedlings within 30 minutes after uprooting, transport in small batches -- not all at once
Level and muddy the field
Not liquid but sticky, with no standing waterField should be well-leveled so that water can reach all the plantsStart puddling and nursery at the same time
Transplant
Transplant Transplant in squares
40X40 cm, 30X30 cm, or 25X25 cmGive space so roots can spread
Do not set in too deeplyPlant extra seedlings along perimeter to replace damaged onesDo not push it in like this
but slip it into the mud like this
WeedingMechanical rotary weeder or rotating hoe is best so oxygenate and aerate soil while weeds are removedWeed field 2-3x before the panicles developFirst weeding will be done 10 days after transplanting (replace any damaged plants)Weed again every 15 days thereafter
Water Management Minimum water useWhen transplanting, just apply enough water to make mud stickyAs stalks grow, allow field to try during tillering — do NOT worry about cracks developing
Lightly flood field until milky phase of grain development (1-2 cm)Keep field flooded only after panicles begin to develop

An Adaptation of SRI: A Case Documentation of Dionito Eñano
Farmer Profile: Dionito Eñano
56 years oldGeneral manager of the Mabini Limers and Farmers Multipurpose CooperativeFather of 12 childrenPractices nature farming
Had health complications and was recommended to adopt an organic-based dietThis influenced him to convert to organic agricultureLack of academic degree was not a setback for him to learn, adopt, adapt and innovate technologiesOwn observations and lessons learned from experience were key factors
Farm Profile6,800 sq. m of landSubdivided parcel of land into 28 smaller plots (kahon)
Done to make the management of farm easierWorks on farm 5-7 AM before breakfast and 5-6 PM before dinner
Staggered plantingWeekly planting, weekly harvest
Gmelina trees surround perimeter of fieldsHas vegetables growing along canal and walkways
Conversion Process
Horizontal not vertical approachIncorporate ash and charcoal from local lime factoryIncorporate peanut shells and coffee hulls from the farmCollect/buy carabao and cow manurePlow rice straw into the soil
Nursery
Container lids and basins are used as seed trays
Only 6-8 of seeds per hectare are used for planting
Pre-transplant
7 day-old seedlings, or at two-leaf stageAs needed, hires 2 workers for ½ day workWeekly planting, thus weekly harvest
Transplant
Spacing, 30 cm X 30 cm
Members of HUBON in action
Pest Management
• Ducks eat insects (mostly mollusks)
• Hand weeding and hand picking of snails
• Gmelina trees and citronella leaves are used to repel insects
• Weeding is done in less than ½ hour using the rotary weeder (considers this as a leisure time activity, as exercise)
Water Management
• Water field one day before weeding
• Use minimum water to allow oxygenation of plant roots
A look at the farm
A beautiful rice field……………...
Recommendations:Incorporate N-fixing trees like Sebania rostrata and Gliricidia sepiumIntroduce Azolla fernsModify fallowing techniques- integrate green manure
Plant rice varieties of similar maturityTake leadership a step further, as perhaps the farm can become a learning centre or a demonstration farm
