Resumo: Residual influence of micronutrient fertilization in rice (Oryza sativa L.) crop in a virgin Red-Yellow Latosol was studied during two years. Increases in rice yield above 800 kg/ha/year were due to Zn even in the smallest doses of 2.8 kg/ha, which were sufficient to get almost optimum yield. The critical level of Zn in the leaves and in the soil was 10.6 ppm and 3.1 ppm, respectively. There were positive correlations between yield and the Zn and K content in the leaves, and negative correlations with N, P, Mg and Cu. The correlations coefficient between Zn in the soil and in the leaves was 0.877, and the regression was liner. Zn lixiviate in the soil up to 20cm and 40cm of depth.

O Zn aumentou a produção acima de 800 kg/ha, anualmente, mesmo na menor dose, de 2,8 kg/ha, que foi suficiente para alcançar produções próximas ao máximo. O nível crítico de Zn nas folhas foi de 10,6 ppm, e no solo, de 3,1 ppm. Houve correlações positivas entre rendimento e teores nas folhas de Zn e K, e negativas com N, P. Mg e Cu. O coeficiente de correlação entre o teor de zinco no solo e nas folhas foi de 0,877, e a regressão foi linear. O zinco lixiviou-se atingindo a camada de 20 cm a 40 cm de profundidade. Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, Ady Raul daAndrade, José Maria Vilela de2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14264Pesquisa Agropecuaria Brasileira; v.22, n.2, fev. 1987; 153-162Pesquisa Agropecuária Brasileira; v.22, n.2, fev. 1987; 153-1621678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14264/8184info:eu-repo/semantics/openAccess2014-09-26T17:38:28Zoai:ojs.seer.sct.embrapa.br:article/14264Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-26T17:38:28Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
