Transcript

  • 1. GriSP PL 3.1. Future management systems & PL 3.2. Resource-conserving technologies for diversified farming systems CSISA Research Platforms J. K. Ladha F. Mussgnug New initiatives / plans for 2013 and beyond
  • 2. GriSP PL 3.1. Future management systems & PL 3.2. Resource-conserving technologies for diversified farming systemsShort-term plans: 1. Adjustment of fertilizer rates in Scenario 2 to 4 in all platforms: Currently not considered: • Nutrient cycling by residue return (app. 10 to 17 t ha-1 yr-1) • Possible higher leaching losses by improved infiltration through CA Nutrient balancing: Estimates or processing of plant samples from platforms? Identification of nutrient deficiencies • Possible micronutrient requirements • Possible antagonistic effects by high K inputs by residues: Mg, etc.
  • 3. GriSP PL 3.1. Future management systems & PL 3.2. Resource-conserving technologies for diversified farming systems Short-term plans: 2. Reestablishment of omission plots in platform scenarios: • Omission plot locations were not altered after each crop 3. Closing of current Tamil Nadu platform and relocation: • Problems with data availability and quality • Current platform site suboptimal for non-rice crops What should be changed: • Closer proximity to CSISA hub • Lighter textured soil that allows - CA-based mechanization options other than mechanical transplanting - Integration of non-rice cereal and legume crops
  • 4. GriSP PL 3.1. Future management systems & PL 3.2. Resource-conserving technologies for diversified farming systems Short-term plans: 3. Closing of current Tamil Nadu platform and relocation (cont.): What should be changed: • Strong emphasis on future water shortages: - integration of AWD / aerobic rice - ZT DSR - No-till mechanical transplanted rice - Non-rice summer season crops 4. Hub-based on-farm testing of promising platform scenarios with progressive farmers
  • 5. GriSP PL 3.1. Future management systems & PL 3.2. Resource-conserving technologies for diversified farming systemsShort-term plans: 5. New CSISA platform in Odisha?
