  1. 1. Experiences of SRI method of Crop cultivation PRADAN,Gaya
  2. 2. PRADAN,Gaya
  3. 3. Gaya
  4. 4. Nalanda
  5. 5. Context• Poor rainfall• Low productivity of food grains• High Migration• High percentage of poor people(Dalit and Backward community)• Dry area(facing draught at regular interval)• High caste Conflicts/tensions
  6. 6. Context• Annual Rainfall more than 900mm but erraticity• High percentage of Mahadalit particularly Bhuiyan• Average holding of poor community 0.5 acres• Since 1956, 151000 acres land distributed among small and marginal communities.• It did not change socioeconomic condition of people,no investment on these lands from mainstreams.
  7. 7. Gaya at Glance• 1. Geographical Area-4.71lac hectare• a. No of blocks-24• b. No of villages-2925• 2. Annual Rainfall-944mm• 3. Net sown area -2.86 lac hec• 4. Fallow land-27654hec• 5. Forest land -77836 hec
  8. 8. SoilsS.No Type of soil Characteristics Admixture of sand & clay, predominantly sandy, found alongside the1 Sandy Loam river beds2 Loamy Soil Found near the hills and formed by rain washings from higher areas.3 Sandy Soil Locally known as balui found near the bank of the river4 Kewal Soil (Black) It is a mixture of clay and loam and is very productive, neutral in nature.5 Foothill Balthar Soil (Red) It is in between the plain and dissected plateau. It is acidic in nature.
  9. 9. soils• As we go from north to south the soil becomes coarsers/Sandy/light.Mostly alluvial but grains of alluvium get coarser as we move towards south.
  10. 10. Gaya• The northern blocks of Gaya are more plain and productive .Less infiltration of extremist.• The southern portion of the district is extension of Jharkhand and land is undulating(Nearly 40-45% area undulating).• 11 of the 24 blocks are infiltrated with extremists.
  11. 11. Nalanda• Western portion adjoining Gaya is similar to Gaya• The Eastern portion faces flood like situation• The rest portion are comparatively better off/developed agriculture with heavy clay soils• Community is politically active with priorities often misplaced,
  12. 12. Problems of people• Food security for 3-5 months only among small and marginal community due to very low productivity of major crops• Absence of extension services in villages• Forced migration
  13. 13. Interventions• Mainly in SRI method of crop cultivation Paddy and Wheat(Food-grain crops) to secure food-grains Rapeseed(Oilseed crops) and vegetables for cash and household consumption Sugar crops for cash and Sugarcane growers• Strengthening the existing ahar/outlets/drainage channels to combat erraticity of rainfall in order to strengthen SRI movement
  14. 14. Strategies of scaling up SRI Technical Resource Team SEW SEW SEW VO backed by VO backed by FC/VO backed by Gp of VRPs Gp of VRPs Gp of VRPs SHG families/ Marginal SHG families/ SHG families/ farmers Marginal Marginal farmers farmers
  15. 15. System of Root Intensification method of Wheat cultivation
  16. 16. Important steps• Hot-water treatment of wheat seeds• Treatment of seeds with Cow urine,Jaggery,Vermicompost• Germinated seed sowing• Wider spacing of 20cmx20cm• 2 seeds/hill• Weeding at 20,30 and 40 Days After Sowing
  17. 17. Items of seed treatment

  21. 21. Intensification of Root in Wheat
  22. 22. Matured wheat crop64 panicles from 2 seeds ofwheat A farmer harvesting her plot
  23. 23. Reproductive growth Phases
  24. 24. Final stage of SRI-Wheat crop
  25. 25. Learnings from SRI-Wheat• The average length of panicle under SRI is 15 cms as compared to 11 cms in normal wheat.• The average number of grains per panicle varies between 60-110 as compared to 18-48 under normal wheat.• The average number of effective tillers per hill varies between 15-25 as compared to 2-4.• Timely sowing and 4-5 irrigations are essential for high productivity.
  26. 26. Learnings--------• The seed rate under SRI-Wheat is 25 kg per hec as compared to 200kg/hec(traditional) and 100 kg/hec (recommended by universities) under standard POP of wheat.• The yield is 25-50% more even under stress condition.• The sowing of wheat under SRI-wheat manually requires more labours per kathha as compared to 1 under normal condition.

  31. 31. One plant of Rapeseed under SRI
  32. 32. Learnings• 50 gms to 250 gms of seeds is sufficient for 1 hectare of rapeseed-mustard cultivation.• The spacing between plants is directly proportional to duration of crop varieties.• One kg of Rapeseed-Mustard has 270000-290000 seeds.

  34. 34. Piloting of SRI-Sugarcane A farmer couple in Matihani village in GayaSugarcane eye extractor district holding seedlings of SRI-Sugarcane
  35. 35. Seedlings of SRI-Sugarcane raised in plastic trays
  36. 36. Tillering from Single node/single seedlingsA small single plant of Plant after 50-60 days ofSugarcane at 15 days transplanting under SRI method
  37. 37. Crop stage after 4 months oftransplanting SRI-Sugarcane
  38. 38. Learnings(ongoing)• Seedlings of 8-12 days old perform better• In dry season transplanting after rainfall starts has better gowth• When canesetting starts dry leaves should be removed regularly.• Cocopit/Neopit alongwith vermicompost facilitates root growth• Planting material is reduced by 80%
  39. 39. Learnings• Shallow transplanting of seedlings(settlings) should be followed with light irrigation.• It facilitates inter cropping.The intercrops should not be of more than 100 days.

  42. 42. Learnings from SRI-Vegetables• The increase in branching in tomato,Chill and brinjal is significantly higher than that of normal practices.• The spacing for building of rhizosphere depends upon nature of vegetables.• The yields have been found higher since three years.
