0719 System of Rice Intensification in Andhra Pradesh

  1. 1. 2 nd National Symposium 3 rd -5 th October, Agartala System of Rice Intensification in Andhra Pradesh Department of Agriculture Andhra Pradesh
  2. 2. General scenario of rice <ul><ul><li>Rice is the most important food crop of India, and it occupies 23.3% of gross cropped area of the country. </li></ul></ul><ul><ul><li>Rice contributes 43% of total food grains production. </li></ul></ul><ul><ul><li>AP stands 6 th in area, 3 rd in production, and 2 nd in productivity and contributes nearly 12% of the national rice production. </li></ul></ul><ul><ul><li>AP farmers grow rice annually in an area of 3.98 M Ha in 22 districts. </li></ul></ul>
  3. 3. Need for SRI <ul><li>Depletion of water resources </li></ul><ul><li>Stagnating rice productivity </li></ul><ul><li>Growing importance of organic agriculture </li></ul><ul><li>Increasing production costs </li></ul><ul><li>Need best utilization of family labour for small and marginal farmers. </li></ul>
  4. 4. Six key principles of SRI <ul><li>1. Young-aged seedlings </li></ul><ul><li>2. Careful single seedling transplanting </li></ul><ul><li>3. Wider spacing </li></ul><ul><li>4. Water management </li></ul><ul><li>5. Weeding </li></ul><ul><li>6. Compost/organic manuring </li></ul>
  5. 5. <ul><li>SRI technology uses: </li></ul><ul><ul><li>Less water </li></ul></ul><ul><ul><li>Less seed (2 kg/ac) </li></ul></ul><ul><ul><li>Fewer plants per unit area (25 x 25 cm) </li></ul></ul><ul><ul><li>Less chemical fertilizers </li></ul></ul><ul><ul><li>More organic manures </li></ul></ul><ul><ul><li>Less pesticides </li></ul></ul>
  6. 6. Tillering is greatly increased: <ul><li>30 tillers per plant are fairly easy to achieve </li></ul><ul><li>50 tillers per plant are quite attainable </li></ul><ul><li>With really good use of SRI, individual plants can have 100 fertile tillers or even more. Why? </li></ul><ul><li>Because there is no set-back to plant growth thanks to early and careful transplanting and no die-back of roots </li></ul><ul><li>Maximum tillering occurs concurrently with panicle initiation </li></ul><ul><li>With SRI, a positive correlation is found between the number of panicles per plant and number of grains per panicle </li></ul>
  7. 7. Increased tillers Increased tillers
  8. 8. Increased yields
  9. 9. Conventional method SRI method Seed rate 25kg/acre 2kg/acre Nursery area 5 cents/acre 1 cent/acre Age of seedlings 30 days(5-6 leaves) 8-12 days(2 leaves) Spacing 15 cm x 10 cm 25 cm x 25 cm Plants/hill 3-4 1 Hills/ sq.m 33 16 Weeding Manual/chemical Mechanical Water management Continuous inundation Keep soil moist till panicle initiation stage
  10. 10. Benefits of SRI 1. Higher yields – of both grain and straw 2. Reduced duration of crop cycle (by 10-15 days) 3. Less chemical inputs 4. Less water requirement 5. Less chaffy grain (%) 6. Grain weight increased without change in grain size 7. Higher head rice recovery rate 8. Withstands cyclonic gales 9. Soil health improves through biological activity
  11. 11. <ul><li>Increase in yield by 26.68% </li></ul><ul><li>Reduction in cost of cultivation </li></ul><ul><li>Lower seed rate </li></ul><ul><li>Less use of fertilizers and pesticides </li></ul><ul><li>Fewer non-filled grains </li></ul><ul><li>More grain weight </li></ul><ul><li>More rice recovery </li></ul><ul><li>Non-lodging </li></ul><ul><li>Harvest early by 10 days </li></ul>Observations in these demonstrations
  12. 12. Action Plan for 2007-08 : Kharif 2007 - Rs. 91.945 lakhs   Incentive of Rs. 3500/- per acre demonstration Component Total cost (Rs) Subsidy allowed (Rs) Application of vermicompost (1 ton/acre) 4000-00 1000-00 (25% subsidy) Supply of cono-weeders and markers 3000-00 2250-00 ( 75% subsidy) Erection of demonstration board 250-00 250-00 (full cost ) Total 7250-00 3500-00
