Acid soils severely reduce maize (Zea mays L.) yield in the tropics. Breeding for tolerance to soil acidity provides a permanent, environmentally friendly, and inexpensive solution to the problem. This study was carried out to determine the relative importance of additive, dominant, and epistatic...

Additive, dominant, and epistatic effects for maize grain yield in acid and non-acid soils
The project validated and disseminated a large number of improved rice-based cropping systems technologies suited to upland agro-ecologies. These improved technologies have good potentials to raise the productivity of water, land, and labor. The innovative strategies employed by the project inclu...

For the 20 million people whose livelihood directly depends on land and water resources in upper catchments of the Mekong and the Red River basins, improving the productivity of rice could help to break the cycle of poverty, food insecurity and environmental degradation that characterizes the a...

Breeding programs for acid-soil tolerance are desirable as a relatively inexpensive and permanent way for increasing maize (Zea mays L.) yield on these soils. Our objective was to compare the genetic effects controlling the expression of maize traits in acid and non-acid soils. Seven related and ...

Land use and land cover changes are driven by human actions and, in turn, drive changes that alter the availability of products and services for people and livestock. For proper planning, these cause-and-effect interrelations need to be understood. This is especially important for Ethiopia where ...
