A general review is presented on how socioeconomics can contribute to agricultural research progress. Research priorities are basically determined by the identification and understanding of the farmers` problems, knowledge of their resources (type of soil, rainfall pattern), farm characteristics,...

The growth of 9 grain legumes under irrigated conditions was analyzed at CIAT to evaluate bean efficiency in grain production. The representative genotypes of each sp. were selected from preliminary var. evaluations. The most efficient spp. in yield production/day were soybeans, cowpeas and beans...

Aspects on mineral nutrition of bean plants and the nature of each nutrient in the soil and in the plant are described. The need for fertilization is briefly justified and the physicochemical form, mobility, and dynamics of the nutrients in the soil and their availability to plants are explained....
Research on lima beans (Phaseolus lunatus) was conducted regarding adaptation, resistance to common bacterial blight (Xanthomonas phaseoli), resistance to leafhoppers (Empoasca kraemeri), and cyanide concn. in lima bean seed. In adaptation studies 36 climbing lima bean lines were selected from th...

In Brazil, the world`s largest bean producer, the annual production value is over US$ billion. Beans contribute more to total national protein consumption than any other product, especially among the poor, who get over 30 percent dietary protein from beans. Available technological options for imp...
