Resumo: | An attempt was made to simulate the mechanical soil layer compaction that may develop in clay soils and to study its effect on the soybean (Glycine max (L.) Merrill) growth. The experiment was carried out in cylindrical pots filled with clay soil in such a way that the medium third was prepared at three density values (1.22, 1.44 and 1.75 g/cm ), keeping she top and bottom layers the original density (0.90 g/cm3). Soybean plants of Santa Rosa cultivar were analyzed as to dry weight of roots, leaves, stems and pods, as well as length of stem, and number of internodes. Compaction of the middle layer at the density of 1.75 g/cm3 hindered root passage and induced a greater root development in the upper parts of the plants induced by the treatments. In this experiment, compaction had no effect on the soybean yield, most likely due to sufficiency of water and nutrients in the soil. |

Merrill). Cilindros de ferro, contendo solo compactado a três densidades diferentes (1,22, 1,44 e 1,75 g/cm3), foram colocados no terço médio dos vasos, intercalando-se duas camadas de solo com densidade original (0,90 g/cm3). Analisou-se o comportamento da variedade Santa Rosa, obtendo-se os dados de peso seco de raiz, caule, folhas e vagens, altura das plantas, número de internódios e estado nutricional. Verificou-se que a densidade de 1,75 g/cm3 impediu totalmente a penetração de raízes e que o aumento da densidade do solo induziu um maior desenvolvimento de raízes na camada superior. Na parte aérea, nenhuma diferença significativa foi observada entre os parâmetros analisados. Neste experimento, a compactação não teve efeito na produção de soja, provavelmente por causa da abundância de água e ao nível adequado de nutrientes.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNogueira, Sandra dos Santos SeváManfredini, Sidneide2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15405Pesquisa Agropecuaria Brasileira; v.18, n.9, set. 1983; 969-976Pesquisa Agropecuária Brasileira; v.18, n.9, set. 1983; 969-9761678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15405/9304info:eu-repo/semantics/openAccess2014-04-16T19:06:32Zoai:ojs.seer.sct.embrapa.br:article/15405Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:06:32Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
