Between 110 and 176 F 6 recombinant inbred lines from a mapping population derived from a cross of upland rice varieties Bala and Azucena have been evaluated for indicators of drought avoidance in sites in the Philippines and West Africa over two dry seasons. A molecular map with 102 RFLP, ...
In field conditions, ascertaining leaf water potential at high frequency is both laborious and detrimental to crop stands. Leaf water potential and six soil and climatic descriptors related to the crop water status were monitored in an upland rice farmer's field in the Philippines. Soil matric ...

in upland cultivation with a smallest reduction being in the upland field with straw mulching.The length and width of rice grain became small and the grinding quality was improved of the rice cultivated in upland soil compared with waterlogged soil.Higher protein content,peak viscosity,through ...
We investigated short- and long-term effects of rice straw application to paddy soils on crop growth, mineralization of straw N, and soil N supply under fl
