Working Group 5
Drought-prone plateau uplands

Extensive areas of the Gangetic Basin in eastern India are plateau uplands subject to severe drought in the dry season and prior to the arrival of the monsoon rains. Unreliable and highly variable rainfall during the monsoons can also restrict crop potential. Other rice production constraints are weeds, infertile soils and seed quality. The intervention strategy is to introduce technologies suitable for local conditions while shortening the time to harvest, which would allow some leeway for planting of postharvest nonrice crops for cash marketings. A diversified and intensified cropping system would give farm households better food security, and they would gradually generate sufficient surplus to enable them to invest further in their farms.

Research themes
  • Improved weed management and crop establishment practices modified from traditional techniques.

  • Nutrient management options based on various fertilizer treatments to improve crop productivity.

  • Farmers' evaluation of varieties with superior performance using their typical management practices.

  • Diversifying cropping systems through intercropping in rice, and introducing new sequence crops, usually for cash income, in a rice field after harvest.

  • Evaluate new methods for seed cleaning, seed storage and seed production in comparison to farmers' traditional practices.

  • Achievements
  • Identified effective crop establishment and weed management techniques for this drought-prone ecosystem.

  • Confirmed the benefit of adjusted nitrogen fertilizer applications for improving crop yield in farmers' fields.

  • Identified promising stress-tolerant varieties through on-farm trials.
