Resumo: | A field experiment was conducted at the National Rice and Bean Research Center of EMBRAPA, Goiânia, Goiás, Brazil, during four consecutive years under sprinkler irrigation using center pivot. The objective of this study was to evaluate effects of plowing at different depths (15 and 30 cm), fertilizer levels (200 and 400 kg ha-1) and crop rotation (R1 = rice-bean; R2 = corn-bean and R3 = rice-wheat-corn-bean) on grain yield, and physical and chemical properties of soil. In general, concentrations of AI, Ca+Mg, P, K and MO in soil decreased during the experimentation period with the agricultural system employed. Under treatment of plowing at 30 cm depth, bulk density at 20 and 30 cm depths were lower as compared to initial values. Plowing treatment at 30 cm depth produced higher grain yield of rice in rotation with wheat-corn and bean as compared to rotation with bean. Bean yield was lower after corn than after rice. Plowing depth had no effect on yield of corn, bean and wheat. Higher yields of rice, corn, bean and wheat were obtained at higher fertilizer level. Agricultural system with highest rentability was corn-bean rotation. |

O objetivo foi estudar diferentes profundidades de aração do solo (15 e 30 cm), doses de adubo (200 e 400 kg/ha) e rotações de cultura (R1 = arroz-feijão; R2 = milho-feijão e R3 = arroz-trigo-milho-feijão) na produção de grãos, economicidade e no desempenho de características fisico-químicas do solo. De modo geral, as concentrações de Al, Ca+Mg, P, K e matéria orgânica no solo diminuíram durante o período de estudo, com os sistemas agrícolas empregados. Nos tratamentos de aração a 30 cm, os valores de densidade aparente a 20 e 30 cm de profundidade do solo foram menores no final em relação ao início do estudo. A aração a 30 cm de profundidade propiciou os maiores rendimentos do arroz, e a cultura produziu mais na rotação com trigo-milho-feijão, do que na rotação com feijão. O rendimento do feijoeiro foi menor após o milho do que após o arroz. A profundidade de aração não teve efeito sobre as produtividades do milho, feijão e trigo. Maiores rendimentos de arroz, milho, feijão e trigo foram conseguidos na maior dose de adubo. A rotação milho-feijão foi a mais rentável.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirada Silveira, Pedro Marquesda Silva, Silvando Carlosda Silva, Osmira FátimaDamacena, Meire Aparecida1994-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4172Pesquisa Agropecuaria Brasileira; v.29, n.8, ago. 1994; 1243-1252Pesquisa Agropecuária Brasileira; v.29, n.8, ago. 1994; 1243-12521678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4172/1463info:eu-repo/semantics/openAccess2011-08-25T11:52:46Zoai:ojs.seer.sct.embrapa.br:article/4172Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2011-08-25T11:52:46Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
