This study aimed to identify the most suitable plant populations, considering different environmental conditions, to express the yield potential of common bean cultivars released or in the process of releasing for regions not included in the initial release. Forty-four experiments were carried out from November 2016 to March 2019, encompassing wet, dry, and winter seasons, across the states of Goiás, Minas Gerais and Paraná. Five plant populations established at sowing (12, 18, 24, 30, and 36 plants m⁻²) were compared in a randomized block design with four replications, using the cultivars BRS FC310, BRS FC409, and BRSMG Uai. Across winter season experiments, the BRS FC310 cultivar consistently displayed higher yield than the others at all plant populations. In contrast, the BRSMG Uai cultivar exhibited the highest yield during the wet season. The maximum grain yields of the three cultivars were higher in the wet than in the winter season and obtained with higher plant populations. Cultivars BRS FC310, BRS FC409, and BRSMG Uai maximized grain yield with, respectively, 28.4, 25.4, and 26.2 plants m⁻² at harvest time in the wet season, and 20.4, 14.0, and 15.2 plants m⁻² in the winter season. ; O estudo teve como objetivo identificar populações de plantas mais adequadas, frente a diferentes condições ambientais, para expressar o potencial produtivo de cultivares de feijoeiro recentemente lançadas ou em processo de extensão de lançamento para outras regiões não contempladas no lançamento inicial. Foram conduzidos 44 experimentos, entre novembro de 2016 e março de 2019, nas épocas das águas, da seca e de inverno, em Goiás, Minas Gerais e Paraná. Foram comparadas, no delineamento de blocos ao acaso, com quatro repetições, cinco populações de plantas estabelecidas na semeadura, 12; 18; 24; 30 e 36 plantas m-2, usando as cultivares BRS FC310, BRS FC409 e BRSMG Uai. A cultivar BRS FC310 foi mais produtiva que as demais em todas as populações de plantas nos experimentos conduzidos durante a época de inverno e a cultivar ... |
