Abstract

Growth and yield of Ouro Negro and BRS MG Talismã cultivars bean grains were characterized by field experiments, in field conditions, at the Coimbra Experimental Station, state of Minas Gerais, Brazil, Federal University of Viçosa, Minas Gerais State, Brazil. Bean vegetative growth and grain yield of two cultivars were evaluated. Samples at 12, 22, 36, 51, 65 and 76 days after emergence were collected to determine foliar area, biomass of different aerial components, foliar area index, absolute growth and net assimilation rates. Grain yield and its components (number of plants per area, number of pods per plant, number of grains per pod and average mass of one hundred grains) were determined at 80 days after emergence (harvest). Vegetative growth of the two cultivars was similar, although the Ouro Negro cultivar had higher accumulation rates of total dry matter, absolute growth rate, foliar area index and net assimilation rate. Relative growth rate was higher in BRS MG Talismã cultivar.
