  • SRI: rendement plus bas est de 5.4 t/ha (ce qui correspond au moyen rendement du temoin). Pour Plus que la moitie des parcelles temoin et traditionelles les rendements sont inferieures que le plus bas rendement de SRI ^5.4 t-ha 17 paysans parmi les 53, ont produit plus que 10 t/ha ce qui represent un tiers Temoin et Parcelle traditionelle sont semblable ou legerement mieux pour une quarantaine de paysans 12 parcelles du Temoin ont produit bien au dela de 6/tha, ce qui correspond a 5 parcelle dans les parcelles traditionelles Meilleure performance du temoin s’explique quelques paysans qui ont voulu battre le SRI, et ont applique tous les moyens et connaissances de techniques ameliores de la riziculture. Egalement, le meilleures rendements ont seulement ete atteint dans les villages qui ont commence au debut de la saison
  • 0892 Community-Based Assessment of SRI in 12 Villages with 60 Farmers in Goundam and Dire, Timbuktu

    1. 1. Community-based assessment of SRI in 12 villages with 60 farmers in Goundam and Dire, Timbuktu
    2. 2. Implementation approach <ul><li>12 villages were enlisted to cooperate in the evaluation based upon interest </li></ul><ul><li>5 farmers were selected by each village community to participate = 60 in total </li></ul><ul><li>Community gave assurances of support </li></ul><ul><ul><li>e.g., labor, adjusting irrigation schedules </li></ul></ul><ul><li>No gifts! Our ‘gift’ was the technical support </li></ul><ul><ul><li>4 field technicians for the 12 villages </li></ul></ul><ul><li>Good data collection to be done </li></ul><ul><li>Control plot started the same day as SRI </li></ul>
    3. 3. 6 Principles of SRI <ul><li>Transplant single seedlings </li></ul><ul><li>At their 2-leaf stage, only 8-12 days old </li></ul><ul><li>Spacing is 25 cm x 25 cm or wider; planted in square </li></ul><ul><li>Use mechanical hand weeder for soil aeration </li></ul><ul><li>Minimum water application during vegetative growth </li></ul><ul><li>Application of organic matter (manure, compost) instead of fertilizer </li></ul>
    4. 4. Land preparation of SRI plots 1. Application of manure (10-15 t/ha) 4. Leveling 3. Breaking up large soil chunks 2. Tilling by hand or by tractor
    5. 5. <ul><li>Mix soil, clay, sand and manure (loose soil) </li></ul><ul><li>Soaking of seeds before planting in nursery (24h) </li></ul><ul><li>Watering, not flooding </li></ul><ul><li>Transplantation after 8-12 days </li></ul>SRI Nursery Quantity of seeds used with SRI 6.15 kg/ha Results Quantity utilized traditionally 40-60 kg/ha Reduction of 85-90%
    6. 6. 2 leaves - 8-12 days old Transplanting of Rice Seedlings
    7. 7. Transplanting SRI Seedlings
    8. 8. 1st Day after Transplanting
    9. 9. Fields of Asseydou Alhassane, Hara-Hara 30 days after nursery establishment SRI Control plot
    10. 10. <ul><li>Incorporating weeds as green manure </li></ul><ul><li>Soil aeration </li></ul><ul><li>Stimulation of root growth </li></ul><ul><li>Redistribution of water across the plot, with leveling effect </li></ul><ul><li>Making nutrients of manure more available to plants </li></ul>Multiple effects of cono-weeder application Section not weeded
    11. 11. SRI Control Plant development
    12. 12. Plant development <ul><li>Higher tiller number per plant in SRI </li></ul>SRI Control
    13. 13. More growth with shorter crop cycle SRI SRI SRI Témoin Témoin Témoin Plant development
    14. 14. --- June | ------------------- July ---------------------| ----------------- August -------------| September ---- Transplanting time of SRI
    15. 15. Transplanting time of SRI --- June | ----------------- July -------------------| ---------------- August -------------| September ----
    16. 16. . .
    17. 17. Rice grain yields (kg/ha) >50% plots < 5.4t/ha 32% plots SRI >10 t/ha 5.4 t/ha
