Resumo: Mn toxicity is a widespread problem in Brazilian soybean (Glycine max (L.) Merrill) fields, and liming is the key to overcome it. The utilization of high rates of lime can eventually increase the occurrence of manganese deficiency, which is discussed in the paper. Soybean cv. Cristalina was grown in 20 l pots containing two Dark-Red Latosols, with and without lime and potassium fertilization. Potassium fertilization can eventualy decrease Mn absorption by soybean, and when associated with liming (pH 6,5) a Mn deficiency was observed in the upper third part of the plant. The deficiency was characterized as an interveinal chlorosis

The deficiency was characterized as an interveinal chlorosisTanto a toxidez como a deficiência de Mn em soja (Glycine max (L.) Merrill), levam a um prejuízo na produtividade. Tem-se recomendado a calagem para superar os graves problemas de toxidez de Mn em soja, mas existem condições potenciais para ocorrer indução de deficiências de micronutrientes, inclusive o Mn. Com o objetivo de explorar esta possibilidade, a cultivar de soja Cristalina foi plantada em vasos, contendo dois Latossolos Vermelho- Escuro de textura média, na presença ou ausência de adubação potássica (50 ug/cm3), e calagem. Os resultados obtidos demonstraram que a adubação potássica pode ter como consequência uma menor absorção de Mn pela soja, e quando associada à calagem (pH 6,5) pode levar à ocorrência de deficiência induzida de Mn, que se manifesta como clorose internerval nas folhas do terço superior da plantaPesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRosolem, Ciro AntonioNakagawa, João2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13506Pesquisa Agropecuaria Brasileira; v.25, n.6, jun. 1990; 833-836Pesquisa Agropecuária Brasileira; v.25, n.6, jun. 1990; 833-8361678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13506/7671info:eu-repo/semantics/openAccess2014-04-17T14:34:39Zoai:ojs.seer.sct.embrapa.br:article/13506Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T14:34:39Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
