Resumo: | The earlier soybean cultivars IAS-5, Planalto, Década, BR-4 and Bragg, and the late cultivars IAC-Foscarin-31, LC 70609 Sulina, CEP 7510 and IAC-4, were evaluated under field conditions of high nutrient availability and proper plant growth conditions. To obtain maximum yields, irrigation was utilized, weeds, insects and diseases were controlled. Higher harvest index values were observed for Planalto, IAS-5, Sulina, Bragg and BR-4 cultivars, which also presented a tendency for longer duration of reproductive period. Harvest index values for all cultivars were negatively associated with plant height, biological yield and lodging. Higher seed yield (kg/ha) were obtained by Bragg, BR-4, Planalto and IAS-5 which presented a better efficiency of conversion of biological yield to seed yield. |

Foram utilizadas práticas de irrigação suplementar e controle de ervas daninhas, insetos e doenças visando altos rendimentos de sementes. Os maiores valores do índice de colheita foram obtidos pelas cultivares Planalto, IAS-5, Sulina, Bragg e BR-4, que apresentaram tendência de maior duração relativa do período reprodutivo. Os valores do índice de colheita associaram-se negativamente aos valores da estatura das plantas, do rendimento biológico e do índice de acamamento. Os maiores rendimentos de sementes (kg/ha) foram atingidos pelas cultivares Bragg, BR-4, Planalto e IAS-5, que apresentaram maior eficiência na conversão do rendimento biológico à produção de sementes.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBraga, Nelson R.Costa, José A.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15201Pesquisa Agropecuaria Brasileira; v.18, n.3, mar. 1983; 253-260Pesquisa Agropecuária Brasileira; v.18, n.3, mar. 1983; 253-2601678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15201/9026info:eu-repo/semantics/openAccess2014-04-16T18:53:52Zoai:ojs.seer.sct.embrapa.br:article/15201Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:53:52Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
