The IRRI upland rice research program - Directions and achievements
The Upland Rice Research Program will continue to address the major constraints in upland systems and conduct research to develop better adapted germplasm and a better basic understanding of socioseconomic, biotic, and abiotic processes. Research outcomes will be used to promote the development of more sustainable and productive rice-based cropping systems.
The program is now soundly focused. More understanding of the socioeconomic dynamics of the uplands has led us to give priority to the dominant integrated rice-based systems and the perennial-based systems, which together cover some 85% of Asian upland rice area. In germplasm improvement, we are developing yield stability in rice by enhancing dought resistance and weed suppressiveness for subsistence systems, and enhancing responsiveness to moderate-high inputs and resistance to blast disease for improved cash-based systems. In resource management, we are developing better nutrient, weed, and nematode management technologies for favorable areas where slopes are low and/or rainfall is reliable.
