  1. 1. System of Rice Intensification (SRI) Mustapha Ceesay NARI Sapu Research Station. Gambia. 2000.
  2. 2. <ul><li>The early transplanted 20 cm spaced plot, 2 weeks after transplanting </li></ul>
  3. 3. <ul><li>The early transplanted 30 cm spaced plot, 2 weeks after transplanting </li></ul>
  4. 4. <ul><li>The early transplanted 40 cm spaced plot, 2 weeks after transplanting </li></ul>
  5. 5. <ul><li>A farmer’s field in the location, transplanted the same day as the SRI trial at 2 weeks after transplanting. </li></ul>
  6. 6. <ul><li>The 30 and 40 cm spacing had enough gap to allow weed growth in the inter-rows at 4 weeks after transplanting </li></ul>
  7. 7. <ul><li>Weeding is done using a roto-weeder </li></ul>
  8. 8. <ul><li>Roto-weeder </li></ul>
  9. 9. <ul><li>The early transplanted 20 cm spaced plot, 4 weeks after transplanting </li></ul>
  10. 10. <ul><li>The conventional method, transplanted with older seedlings under permanent flooding, 2 weeks after transplanting </li></ul>
  11. 11. <ul><li>The conventional method in the forefront and the SRI in the background </li></ul>
  12. 12. <ul><li>The early transplanted </li></ul><ul><li>seedlings had a single and thick-layered crown root, whereas the late </li></ul><ul><li>transplanted ones had 2 </li></ul><ul><li>or 3 layered crown roots. </li></ul>
  13. 13. <ul><li>The SRI plots looking very spectacular at 4 weeks after transplanting. The choice of variety does not seem to have any impact, likewise the wider spacing. </li></ul>
