Resumo: | Phosphorus deficiency is one of the most important growth limiting factors in crop production in oxisols under cerrados of central Brazil. The objective of this study was to evaluate the effect of P fertilization on growth, yield and nutrients uptake by wheat in a dark-red latosol under greenhouse conditions. The P treatments applied were 0, 25, 50, 75, 100, 125, 150, 175 and 200 mg P/kg-1 of soil. Root dry weight and grain yield were significantly affected by P fertilization. Adequate P level for dry matter production was about 75 to 100 mg of P/kg-1, of soil, whereas for grain yield it was about 175 mg of P/kg-1 of soil. Distribution of nutrients in different plant parts showed roots retaining maximum Fe; tops maximum K, Ca, Mg and Mn; grains maximum P and considerable amount of Mg and Zn. Concentrations of Ca and Mg increased with P fertilization, but Zn, Fe and Cu contents of plant tops decreased with increasing levels of P. |

O objetivo deste estudo foi de avaliar o efeito do fertilizante fosfatado sobre o crescimento, produção e absorção de nutrientes pelo trigo, utilizando um Latossolo Vermelho-escuro, em casa de vegetação. Os tratamentos com fósforo foram de 0, 25, 50, 75, 100, 125, 150, 175 e 200 mg de P/kg-1 de solo. A aplicação do fertilizante fosfatado afetou significativamente o peso seco das raízes e da parte aérea, e a produção de grãos. O nível adequado de P para produção de matéria seca situou-se em torno de 75 a 100 mg de P/kg-1 e para a produção de grãos, em aproximadamente 175 mg de P/kg-1 de solo. A distribuição de nutrientes em diferentes partes da planta mostrou maior concentração de Fe nas raízes, de Ca e Mg na parte aérea e de P nos grãos, que também apresentaram considerável quantidade de Mg e Zn. As concentrações de Ca e Mg aumentaram com a aplicação do fertilizante fosfatado, mas as concentrações de Zn, Fe e Cu, na parte aérea, diminuíram com o aumento de P.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFageria, Nand Kumar2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13451Pesquisa Agropecuaria Brasileira; v.25, n.4, abr. 1990; 531-537Pesquisa Agropecuária Brasileira; v.25, n.4, abr. 1990; 531-5371678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13451/7572info:eu-repo/semantics/openAccess2014-04-17T14:30:51Zoai:ojs.seer.sct.embrapa.br:article/13451Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T14:30:51Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
