Transcript

  • 1. Welcome SRI Presentation by SRI National Network Bangladesh contact person Dr. Muazzam Hussain May 26, 2010
  • 2. With Thanks
    • Dr. Muzzam Hussain extends thanks and gratitude to OXFAM , on behalf of
    • SRI NNB and BRF for:
    • Moral support
    • Resource support
  • 3. System of Rice Intensification (SRI)
    • Understanding SRI
    • Implementation of SRI
    • Benefits of SRI
    • Challenges in SRI
    • Climate Change Impact on Rice Cultivation
    • SRI and Adaptation to Climate Change
    • SRI in Bangladesh
  • 4. Understanding SRI
    • It is all about a plant
  • 5. Understanding SRI
    • But no magic
  • 6. Why deal with plant
    • Higher yield
  • 7. Yield Concerns
    • Healthy plant
  • 8. Healthy Plant
    • SKIT
    • ( to be provided )
    • Good Seed
    • Good Knowledge
    • Good Information
    • Good Technology
    • SWALTS
    • ( to be facilitated )
    • Living Soil
    • Sufficient Water
    • Dynamic Air
    • Plenty of Light
    • Appropriate Time
    • Suitable Space
  • 9. No alternative to
    • Good Seed
    • Good Knowledge
    • Good Information
    • Good Technology
  • 10. Living Soil
    • Balanced ingredients
    • Functioning organisms
    • Mechanics of aeration
    • Soil is a living factory of nutrients
  • 11. Sufficient Water
    • Just as much needed for the plant
    • Adequate mix of minerals
    • Water is a backward support for nutrients
  • 12. Dynamic Air
    • Mechanism for provision of air
      • Pores in the soil
      • Manipulation of soil for aeration
    • Air is a forward support for nutrients
  • 13. Plenty of Light
    • Positioning for least interrupted light
      • Appropriate distance
      • Physical environment (no big tree / shed)
    • Light is ignition and generation of nutrients
  • 14. Appropriate Time
    • Period of cultivation
    • Season for cultivation
    • Dating sawing and harvesting
    • Time of transplantation
    • Time and timing is risk management of yield
  • 15. Suitable Space
    • Weather
    • Climate
    • Environment
    • Physical area
    • Appropriation of space
    • Space is the ruler of vegetation
  • 16. Implementation of SRI
    • Group Approach
    • Farmers School Approach
    • Scheme Approach
  • 17. Implementation of SRI
    • Small portion of area in farmers field
    • Demonstration plot
    • Season-long experimental observation
  • 18. Implementation of SRI
    • More than one season
    • Seed-to-seed period of learning
  • 19. Implementation of SRI
    • Learning oriented
    • Yield optimization
    • Appreciating the complexity of rice cultivation
    • Local knowledge
  • 20. Implementation of SRI
    • Partnership between implementing Agency and the farmer in the period between initiation and graduation of a SRI Program
  • 21. Salient Features of SRI Practice
    • Increases yield
    • Reduces external inputs
    • Environment-friendly
  • 22. Benefits of SRI
    • Reduction of irrigated water quantity by 30% to 40%
    • Reduction in seed quantity by >75%
    • Reduction in damage by rodents
    • Keeps up threshold of damage by pests
    • Most number of tillers productive
    • Decrease in external inputs
  • 23. Benefits of SRI
    • Less probability of damage due to flood
    • Stems of SRI rice plant are thicker – more resistant to storm damage
    • Roots of SRI rice plant are deeper – more drought-resistant
  • 24. Benefits of SRI
    • Yield increased by 20% to 200%
    • Sustained optimum yield rate
    • Increase yield of indigenous variety
    • Earlier maturity (by 7-20 days)
    • Higher straw yield
    • Resource-efficient production
  • 25. Benefits of SRI
    • Maximum use of local resources
    • New land area becomes feasible for rice cultivation
    • Active soil aeration
    • Healthy soil
    • Hand weeding with push-weeder is easier
  • 26. Challenges in SRI
    • Momentary challenges
      • Difficulty in transplanting young seedlings
      • Frequency of irrigation
      • Increase in weeding (frequency)
    • Persistent challenges
      • Weed control
      • Irrigation pump management
      • Power / fuel
  • 27. Flooding
    • Timing
    • Early maturity
    • Indigenous varieties feasible
    • Faster recovery / establishment
  • 28. Drought
    • Thicker stems and deeper roots
    • Healthy soil
    • Water retention in soil is higher
  • 29. Cyclone
    • Timing
    • Thicker stems - more flexible, less lodging
    • Indigenous varieties favorable
  • 30. Other Hazards -- Biotic
    • Pest infestation
    • Soil nutritional depletion
    • Disease infestation
  • 31. Other Abiotic - Physical
    • Water stagnation
    • Prolonged period of inundation
    • Salinity
    • Lowering of underground water level
    • Variance on time of rainfall
    • Variance in amount of rainfall
  • 32. Other Abiotic - Climatic
    • Cold spells
    • Hot spells
    • Fog
    • Global warming – higher temperatures
    • Greenhouse gases
    • Hailstorms
    • Tornados
  • 33. Other Abiotic - Modernization
    • ‘ Green Revolution’ orientation
    • Homogeneity of crops - vulnerability
    • Genetic uniformity - vulnerability
    • Monoculture - vulnerability
  • 34. SRI in Bangladesh
    • Farmers has accepted
    • Invariably practicing
    • Scientists and policy-makers unanimously called for joint effort in SRI research
    • Expansion of SRI / dissemination
    • Strengthening SRI National Network
  • 35. Food for Thoughts
    • Rice plant is not really aquatic – it can survive in standing water, but does not thrive
    • With SRI, rice can be grown in land usually not accepted as suitable for rice cultivation
    • SRI as a principle of combination of practices is being extended to management of other crops – sugar cane, wheat, etc.
  • 36. Food for Thoughts
    • Can be difficult to convince farmers in first season – need to see results for themselves
    • SRI calls for change in age-old traditions in rice cultivation – change is generally hard for people to accept and engage in
    • But SRI benefits are multiple, visible, and quick – so this gives incentives for change
  • 37. Food for Thoughts
    • More research is required
      • to better understand
      • to innovate
            • for household income
            • build resilience of farmers
            • capacity of farmer to cope with odds
    • Not just ‘research’ but simple demonstrations to show results
  • 38. Way Forward
    • More research and demonstrations
    • Farmers capacity-building
    • Rights approach
    • Policy advocacy
    • Gender perspective
    • Joint efforts
    • Core funding for SRI NNB is needed
