  1. 1. <ul><ul><li>Mushtaq A. Gill </li></ul></ul><ul><ul><li>Director General Agriculture </li></ul></ul><ul><ul><li>(Water Management), Punjab, Pakistan </li></ul></ul>Increasing Water Productivity of Rice through Adoption of System of Rice Intensification (SRI)
  2. 2. MAJOR CHALLENGES Low Land and Water Productivity Degrading Land Resource Base Depleting Aquifers Dwindling Land for Agriculture High Water Losses Shrinking Water Resources Increasing Population Pressure Food Security
  3. 3. YIELD OF MAJOR CROPS IN PAKISTAN (Kg/ha) Yields are almost stagnant for the past decade
  4. 4. <ul><li>Insufficient water availability </li></ul><ul><li>Improper water management </li></ul><ul><li>Undulated topography </li></ul><ul><li>Sub-optimal plant population </li></ul><ul><li>Imbalanced use of fertilizers </li></ul><ul><li>Deterioration of soil fertility </li></ul><ul><li>Inhumane & laborious method of transplanting </li></ul>RICE PRODUCTION CONSTRAINTS
  5. 5. SYSTEM OF RICE INTENSIFICATION Punjab Experience <ul><li>Start with precisely levelled fields </li></ul><ul><li>Early transplantation of young seedlings, only 8-15 days old (9-12 cm height, 2-leaf stage) </li></ul><ul><li>Maintain moist field with just thin layer of water </li></ul><ul><li>Wide-space planting in square pattern (25 x 25 cm) </li></ul><ul><li>Planting only one plant per hill </li></ul><ul><li>Transplantation of nursery in evening </li></ul>
  6. 6. <ul><li>Enhances Productivity </li></ul><ul><ul><li>Increase yield 30-50% or more </li></ul></ul><ul><ul><li>Larger panicles (about 200-300 grains/panicle) </li></ul></ul><ul><ul><li>Higher grain weight (15-20%) </li></ul></ul><ul><li>Conserves 25-50 % water </li></ul><ul><li>Reduces seed requirement by 80-90% </li></ul><ul><li>Improves livelihood </li></ul><ul><ul><li>20 % reduction in cost of production </li></ul></ul>SYSTEM OF RICE INTENSIFICATION (SRI) Impact Assessment
  7. 7. PROMOTION OF SRI SRI Seminars at UAF and in Okara Project area Trials at Univ. of Agriculture Faisalabad for adaptation of SRI
  8. 8. CROP ESTABLISHMENT AND IMPACT
  9. 9. IMPACT OF SRI Year Area (acres) No. of Farmers Water Saving (AF) Net Income (US$) 2006 10 4 13.17 2,395.90 2007 25 10 32.93 5,989.75 Total (US$) 8,385.65
  10. 10. RESOURCE CONSERVATION TECHNOLOGIES BEING EVALUATED AND ADOPTED FOR RICE <ul><li>System of Rice Intensification (SRI) </li></ul><ul><li>Direct-Seeded Rice (DSR) </li></ul><ul><li>Zero-tillage Dry Sowing </li></ul><ul><li>Leaf Colour Chart (LCC) </li></ul><ul><li>Brown Manuring </li></ul><ul><li>Surface Mulching </li></ul>
