Resumo: The effects of different soil tillage systems and methods of fertilizers application were studied on soybean production following wheat grown on conventional tilled soil. The experiments were conducted in a dark red latosol, clay textured soil, during the years 1971, 1972, and 1973. Significant differences were observed among the soil tillage systems. Minimum tillage showed higher productivity than the conventional tillage system and minimum tillage, with two disc harrowings (levelers) was the best treatment during the three years. Under minimum tillage systems, the soybean plants present a high root concentration in the most superficial layer of the soil, which has a high level of fertility, possibly the reason for the present results.

Merrill) em sucessão ao trigo cultivado com preparo de solo convencional. Os experimentos foram realizados em latossolo vermelho-escuro, textura argilosa, nos anos de 1971, 1972 e 1973. Entre os sistemas de preparo do solo empregados, ocorreram diferenças significativas. Os sistemas de preparo mínimo do solo apresentaram maiores produtividades que os sistemas de preparo convencional, sendo que o preparo mínimo com duas gradagens (niveladoras) mostrou-se, nos três anos de estudo, como o melhor tratamento. Nos sistemas de preparo mínimo, a soja concentra suas raízes na camada mais superficial do solo, justamente a camada mais fértil, o que poderia ter possibilitado as maiores produções verificadas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRamos, MiltonDedecek, Renato2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16669Pesquisa Agropecuaria Brasileira; v.14, n.2, fev. 1979; 149-153Pesquisa Agropecuária Brasileira; v.14, n.2, fev. 1979; 149-1531678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16669/10979info:eu-repo/semantics/openAccess2014-04-15T19:23:20Zoai:ojs.seer.sct.embrapa.br:article/16669Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:23:20Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
