Resumo: | In the growing season of 1978/79, field experiments were conducted in two regions of Minas Gerais state, Lavras and Patos de Minas, with the objective of providing informations to the fertilizing recommendations in the corn-beans (Zea mays L.) - (Phaseolus vulgaris L.) intercrop system. The experimental design used was the randomized block according to a scheme of split plot, with four replications. The split plot treatments were a combination of three levels of nitrogen (0-75-150 kg/ha) with three levels of P2O5 (0-150-300 kg/ha). For the bean crop, a significant interaction between the fertilizer level and the arrangement used was found. In the experiment conducted in Lavras, best responses were obtained for P2O5, and in Patos de Minas, for nitrogen. The estimates of levels of fertilizers which garantee bigger profits varied in relation to the arrangement, and the highest values were found in the arrangement where beans and corn were planted on the same line. The results show the possibility of increasing income to producers through the use of modern technologies, even in a traditional practice as that of the intercropping system. |

Utilizou-se o delineamento em blocos casualizados, segundo um esquema de parcela subdividida, com quatro repetições. Os tratamentos das subparcelas foram uma combinação de três níveis de nitrogênio (0-75-150 kg/ha) com três níveis de P2O5 (0-150-300 kg/ha). Constatou-se, para a cultura do feijão, uma interação significativa entre o nível de fertilizantes utilizado e o arranjo usado. No experimento de Lavras, as maiores respostas foram obtidas para P2O5 e, em Patos de Minas, para nitrogênio. As estimativas das doses dos fertilizantes que forneceriam o maior lucro variou com o arranjo utilizado, sendo que os maiores valores foram obtidos para o arranjo em que o feijão foi semeado na mesma linha do milho. Os resultados obtidos evidenciam a possibilidade do incremento na renda dos agricultores com o uso de insumos modernos, mesmo em uma prática tradicional como a consorciação de culturas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCecília, Fernando Costa SantaRamalho, Magno Antônio PattoGarcia, João Carlos2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16274Pesquisa Agropecuaria Brasileira; v.17, n.9, set. 1982; 1285-1291Pesquisa Agropecuária Brasileira; v.17, n.9, set. 1982; 1285-12911678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16274/10459info:eu-repo/semantics/openAccess2014-04-16T16:39:47Zoai:ojs.seer.sct.embrapa.br:article/16274Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T16:39:47Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
