Resumo: | To study the causes of the lack of seed set in soybeans 4 x 4 x 2 factorial split-plot design was used. The variables were: four different planting dates, four fertilizer treatments and two varieties, with four replications. The locality was an experimental field of the Federal Rural University of ("Baixada Fluminense") Rio de Janeiro. There were no significant differences between the two varieties, Pelicano and Majos. The chemical fertilizer PK, Mg and E (micronutrients) did not influence the seed set. Among the four dates of planting, the planting in September showed the lowest percentage of empty pods, and the planting in October showed the highest. Other traits, influenced by planting date, were also analysed: plant hight, bean production and the weigh t of 100 seeds. |

Foi usado um fatorial 4 x 4 x 2 em blocos partidos em 4 épocas com 4 adubações, 2 variedades e 4 repetições, executado na Baixada Fluminense, Rio de Janeiro. Não se encontraram diferenças significativas entre as duas variedades Pelicano e Matos. Os adubos químicos PK, Mg e E (micronutrientes) também não influenciaram a granação. Entre as quatro épocas estudadas, a época de plantio de setembro é a que apresentou menor porcentagem de falta de grãos na vagem e a época de outubro, a maior porcentagem. São apresentados também outros dados influenciados pelas épocas de plantio: altura das plantas, produção, peso de 100 sementes.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSandoval, Orestes VelásquezGroszmann, Américo2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17803Pesquisa Agropecuaria Brasileira; v.4, n.1, 1969: Série Agronomia e Veterinária; 97-102Pesquisa Agropecuária Brasileira; v.4, n.1, 1969: Série Agronomia e Veterinária; 97-1021678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17803/11933info:eu-repo/semantics/openAccess2014-04-15T18:25:41Zoai:ojs.seer.sct.embrapa.br:article/17803Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T18:25:41Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
