Resumo: | The objective of the present study was to determine the importance of the pre-flowering growth stage for common bean yield. In two assays, the common bean BRS-Pérola, BRS-Valente and Jalo Precoce cultivars were sown at five different dates, from April to August, in 2001 and 2002, at Embrapa Arroz e Feijão, in Santo Antônio de Goiás, Goiás State, Brazil. The experiments were carried out under conventional tillage, in a randomized split-plot block design, with four repetitions. Physiological parameters related to common bean plant growth, development and yield were correlated with temperatures and solar radiation incidence, during the pre-flowering plant growth period. Increases of minimum temperature, solar radiation, and N absorption rate, and decrease in N efficiency use, up to the third trifoliolate leaf stage, were correlated with yield reduction. The phenological period between emergence and third trifoliolate leaf is the most important one for common bean yield determination, when compared with the total pre-flowering period. KEY-WORDS: Phaseolus vulgaris; common bean development; temperature; solar radiation. |

Em dois ensaios, as cultivares BRS-Pérola, BRS-Valente e Jalo Precoce foram semeadas em cinco épocas, entre abril e agosto de 2001 e 2002, em área experimental da Embrapa Arroz e Feijão, em Santo Antônio de Goiás, GO, próxima a uma estação meteorológica. Os ensaios foram instalados em sistema convencional de preparo de solo, em delineamento experimental de blocos ao acaso, com parcelas subdivididas e quatro repetições. Características fisiológicas relacionadas a crescimento, desenvolvimento e produtividade foram correlacionadas com temperaturas e radiação solar incidentes no período. Aumentos na temperatura mínima, radiação solar e na taxa de absorção de N e diminuição na eficiência do uso de N, até o terceiro trifólio, foram correlacionados com redução na produtividade. Na fase de pré-floração, o subperíodo entre a emergência e o terceiro trifólio é o mais importante para a determinação do rendimento de grãos do feijoeiro.
