Resumo: | This work was carried out in the field to study the relationship among the appearence of intervein chlorosis of the cassava (Manihot esculenta Crantz) leaves, the nutritive state of the plants, and the soil conditions. Samples of leaves taken from chlorotic and non-chlorotic plants, as well as, samples from the soil around them, were collected and analyzed. The manganese was the chemical element identified as the cause of cassava's leaf chlorosis. The symptoms of manganese deficiency appeared on the cassava leaves, when this nutrient reached levels bellow 20 ppm in the leaves. Low contents of Mn in the leaves and appearence of symptoms of its deficiency occurred in cassava when pH values were superior to 5.8 and the quantities of Ca++ and Ca++ + Mg++ in soil were above 3.8 e.mg/100 g and 5.2 e.mg/100 g respectively. |

O Mn foi identificado como causa da clorose, quando este nutriente chegava abaixo do nível de 20 ppm nas folhas de mandioca. Baixos teores de Mn nas folhas e a exteriorização dos sintomas de deficiência do nutriente ocorreram quando os valores de pH do solo eram superiores a 5,8 e quantidades de Ca++ e Ca++ + Mg++ no solo acima de 3,8 e.mg/100 g e 5,2 e.mg/100 g, respectivamente.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSantos, Zorilda Gomes dosTupinambá, Evandro Almeida2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16354Pesquisa Agropecuaria Brasileira; v.17, n.11, nov. 1982; 1541-1546Pesquisa Agropecuária Brasileira; v.17, n.11, nov. 1982; 1541-15461678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16354/12143info:eu-repo/semantics/openAccess2014-04-15T19:48:23Zoai:ojs.seer.sct.embrapa.br:article/16354Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:48:23Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
