  7. 7. Issues of SRI need to be discussed <ul><li>Advances of SRI: </li></ul><ul><li>Increasing rice yield without increasing chemical inputs (benefit for poor) </li></ul><ul><li>Reducing cost of seeds (suitable for poor, using hybrid variety) </li></ul><ul><li>Reducing of transplanting labor (benefit for woman) </li></ul><ul><li>Increasing efficience of land use, labor, capital investment </li></ul><ul><li>Saving water (suitable for uplands) </li></ul><ul><li>Reducing pest and deseases (support for environment) </li></ul><ul><li>Reducing methane emission (support for environment) </li></ul>
  8. 8. <ul><li>Feasibility of applying SRI in the Northern Uplands </li></ul><ul><li>“ None-package technology” is suitable for upland/fragile condition </li></ul><ul><li>Small plot and farm </li></ul><ul><li>Hard working famers </li></ul><ul><li>Save water </li></ul><ul><li>Seedling making (nilon cover) </li></ul><ul><li>Reduce seed cost fitting for poors and deficit of capital </li></ul><ul><li>Extension network developed </li></ul>
  9. 9. <ul><li>Difficulties that SRI is facing </li></ul><ul><li>Optimum SRI practice on various land </li></ul><ul><li>High risk for young seedling due to cold during Spring season </li></ul><ul><li>Lack of water, farmers are affraid to draigned </li></ul><ul><li>Degraded and poor soil in the NMA </li></ul><ul><li>Weed problem due to poor soil and lack of water </li></ul><ul><li>Golden snail </li></ul><ul><li>Water lodging field dificult to draigned </li></ul><ul><li>Farmer’s believe and habit on transplanting density </li></ul><ul><li>Integrated SRI into DARD’s rice growing guidline </li></ul><ul><li>Lack of fund to support for SRI research and extension </li></ul>
  10. 10. Research/solution Problems Possible solution Research Optimum SRI practices on various variety, land and crop seasons   Farmer participatory research (FPR) -      SRI for photo-sensitive varietry -      SRI on irrigated and fertile soil, poor & sandy soil -      SRI in spring, summer Death of young seedling due to cold -       Timing of transplanting -       Water control Role of phosphorus to protect seedling from cold Lack of water, farmers are affraid to draigned   Testing SRI on rainfed land Golden snail - Pick up when water transparency after harrow Using trap to catch up snail
  11. 11. Problems Possible solution Research Water lodging field dificult to draigned -      Diging canel Testing SRI on lodging land Disadoption: -      Farmer’s believe and habit on transplanting density -      Reasons and factors of disadoption -      Demostration -      Training/TOT -      Farmer club, FFS -      Produce material Survey on farmer’s opinion and evaluation Integrated SRI into DARD’s rice growing guidline (quy tr×nh) Workshop on SRI for DARD, Academic, NGOs, Farmers   Lack of fund to support for SRI research and extension -      TNU’s research program -      FAO, DANIDA.? -      Cornell U.?  
  12. 12. <ul><li>Other basic research: </li></ul><ul><li>Long-term effect of SRI on yield stability, soil nutrient and characteristics </li></ul><ul><li>No-till cultivation </li></ul><ul><li>Pest and deseases </li></ul><ul><li>SRI for other crops and farming systems </li></ul>
  13. 13. <ul><li>Collaboration on SRI research for uplands </li></ul><ul><li>Collaboration on training: SRI short training courses/TOT </li></ul><ul><li>Collaboration on SRI regional/international workshop </li></ul>Suggestions for cooperation between TNU and Cornell University
