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 whereas the pigeon pea had the highest absolute yield. LAD from emergence to physiological maturity was highly correlated with the yield, indicating that the efficiency of available leaf area (yield/LAD) was relatively similar for the 9 species. Rapid leaf area growth in beans contrasts with the slow leaf area growth in pigeon peas and superior growth in peanuts. Bean var. had one of the highest HI and the lowest production of DM of all the legumes studied. Based on this data, it was concluded that beans are extremely efficient in economic yield production as compared to other legumes. (AS-CIAT)
