Resumo: | The aim of this research was to study the plant growth in height and the dry matter accumulation pattern along the bean (Phaseolus vulgaris L.) crop cycle. Four field experiments were carried out in Lavras (winter-spring 2002) and other were performed in Madre de Deus de Minas, MG (dry crop season 2005) with common bean, cvs. Ouro Negro and BRS MG Talismã, under no-tillage and conventional crop systems. Every seven days 10 or 20 plants were sampled to height measurements and other 20 plants for dry matter evaluation. The experiments were carried out in randomized block outlines with three replications and 11 or 12 treatments (sampling times). The data were treated with a variance and regression analysis and representative curves of the evaluated variables were fitted and adjusted. The growth curves had showed that the maximum height was reached by the 50 DAE in no-tillage crop system while in the conventional crop system the bean kept on growing up to the 72-73 DAE, closing further in field. The pattern of dry matter accumulation showed that there was a small increment until the 21-24 DAE for the two cultivars. The maximum accumulation could be observed in the no-tillage croping systems by the 75-76 DAE for the cv. Ouro Negro and by the 80-81 DAE for the cv. BES MG Talismã. In general, the highest rates of dry matter accumulation were verified by the 45-48 DAE. |

O delineamento experimental foi feito com blocos casualizados com três repetições e 11 ou 12 tratamentos (épocas de coleta). De 7 em 7 dias foram amostradas 10 ou 20 plantas para determinação da altura, através do comprimento da haste principal, e outras 20 plantas para determinação do peso da matéria seca da parte aérea após secagem em estufa com circulação de ar a 65-70ºC até peso constante. Os dados foram submetidos a análises de variância e regressão, com ajuste de curvas representativas do comportamento das características avaliadas. Em plantio direto, a altura máxima foi alcançada aos 50 DAE, enquanto no plantio convencional o feijoeiro continuou crescendo até os 72-73 DAE, ocorrendo fechamento mais tardio da lavoura. As cvs. Ouro Negro e BRS MG Talismã mostraram padrões de acúmulo de matéria seca muito próximos, com pouco incremento até os 81 DAE, na BRS MG Talismã, e ambas alcançaram maiores acúmulos em plantio direto. Em geral, as maiores taxas de acúmulo de matéria seca foram verificadas entre 45-48 DAE.Editora da Universidade Federal de Lavras2008-12-012015-04-30T13:34:57Z2015-04-30T13:34:57Z2015-04-30info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articletext/htmlhttp://www.scielo.br/scielo.php?script=sci_arttext&pid=S1413-70542008000600001VIEIRA, N.
