Resumo: The objective of this work was to evaluate the influence of nitrogen doses on mineral nutrition and yield of macadamia nut (Macadamia integrifolia). The experiment was carried out during three agricultural years, in Jaboticabal, SP, Brazil. The experimental design was a complete block with four replicates. Five doses of N (0, 50, 100, 150, and 200 kg ha-1 per year), applied as urea, were evaluated. The increase in N doses increased the nutrient concentration in the leaves and the yield of nuts and almonds. Ca, Mg, and S contents decreased and the ones of Fe and Mg increased linearly with N fertilization. Nut and almond yields were positively correlated with leaf N concentration, and the range from 14 to 18 g kg-1 allowed the highest yields. The dose of 150 kg ha-1 of N per year provides higher nut yields, without reducing the recovery rate of almonds.

O experimento foi conduzido durante três anos agrícolas, em Jaboticabal, SP. Utilizou-se o delineamento experimental de blocos ao acaso, com quatro repetições. Foram avaliadas cinco doses de N (0, 50, 100, 150 e 200 kg ha-1 por ano), aplicadas na forma de ureia. O aumento nas doses de N aumentou o teor do nutriente nas folhas e a produtividade de nozes e amêndoas. Os teores de Ca, Mg e S diminuíram e os de Fe e Mg aumentaram linearmente com a adubação nitrogenada. A produtividade de nozes e de amêndoas correlacionou-se positivamente com o teor de N nas folhas, e a faixa de 14 a 18 g kg-1 foi a que possibilitou as maiores produtividades. A dose de 150 kg ha-1 de N por ano proporciona maior produtividade de noz, sem reduzir a taxa de recuperação de amêndoas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAgência Paulista de Tecnologia dos Agronegócios, APTA.Perdoná, Marcos JoséMartins, Adriana NovaisSuguino, EduardoSoratto, Rogério Peres2013-06-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14157Pesquisa Agropecuaria Brasileira; v.48, n.4, abr. 2013; 395-402Pesquisa Agropecuária Brasileira; v.48, n.4, abr. 2013; 395-4021678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14157/11350https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/14157/9499info:eu-repo/semantics/openAccess2013-06-27T17:48:18Zoai:ojs.seer.sct.embrapa.br:article/14157Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-06-27T17:48:18Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
