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...
Some basic concepts of physiology are presented in relation to bean cultivation, and the external and internal factors affecting crop development and production are described: the environment (edaphic and climatic factors), photosynthesis and factors that affect it (light, CO2, O, temp., wind and...
Common beans (Phaseolus vulgaris L.) are an important world crop with a relatively low productivity in most cropping systems. Physiological factors influencing yield are discussed in this paper with respect to field research in the tropics. The comparative earliness of the majority of the germpla...
CIAT has conducted research to develop a method for selecting drought-tolerant genotypes. Bean var. were planted during the dry season. Irrigation was suspended at the initiation of flowering in the dry treatment and the control treatment continued to be irrigated to avoid water shortage. During ...
