Resumo: In a field experiment of Valencia orange (Citrus sinensis Osbeck) growing in a sandy acid soil, with 4 N, 3 P and 4 K fertilizer levels, the effects of NPK fertilization on the nutrient concentration in the leaves was evaluated. N and Cu contents in the leaves were high, while P and Zn levels were low, in all treatments. Increasing the levels of N, P2O5 and K2O fertilization resulted in an increase of the N, P and K concentration in the leaves, respectively. Crescent levels of N fertilization raised Mn and decreased Ca concentration in the leaves. P and K contents in the leaves correlated positively. With a great availability and absorption of K, reduction on the foliar contents of Mg and Ca occurred.

A concentração de N e Cu nas folhas foi excessiva, e a de P e Zn, baixa. Doses crescentes de N, P2O5 e K2O aumentaram a concentração foliar de N, P e K, respectivamente. Doses crescentes de N aumentaram a concentração foliar de Mn e reduziram a de Ca. Teores foliares de P e K correlacionaram positivamente. Maior disponibilidade e absorção de K reduziu a concentração foliar de Mg e Ca.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBasso, CloriMielniczuk, JoãoBohnen, Humberto2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15132Pesquisa Agropecuaria Brasileira; v.18, n.1, jan. 1983; 17 - 21Pesquisa Agropecuária Brasileira; v.18, n.1, jan. 1983; 17 - 211678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15132/8914info:eu-repo/semantics/openAccess2014-04-16T16:40:55Zoai:ojs.seer.sct.embrapa.br:article/15132Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T16:40:55Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
