Resumo: The effects of N, P, and K applications on yield and fruit quality of orange (Citrus sinensis (L.) Osbeck) was studied in a factorial experiment carried out in a Yellow Latosol, of the Coastal Plateau of the Northeast of Brazil. Zero, 150 e 300 kg ha-1 N as urea; 0, 26 and 52 kg ha-1 of P as concentrated superfosfate and 0, 96 and 192 kg ha-1 of K as KCl were used. A linear yield response to N was observed in one, out of four years of observation. Nitrogen decreased fruit size and had no influence on fruit quality measured by percentage of juice, total soluble solids, acidity and ratio total soluble solids/acidity. Yield was highly responsive to P in each year observed. The nutrient increased percentage of juice and the total soluble solids/acidity ratio. Potassium increased yield and fruit size, but decreased the total soluble solids/acidity ratio.

Osbeck), foi instalado um experimento fatorial, em um Latossolo Amarelo dos Tabuleiros Costeiros. As doses de N, P e K foram, respectivamente, de 0, 150 e 300 kg ha-1 de N na forma de uréia, 0, 26 e 52 kg ha-1 de P na forma de superfosfato triplo, e de 0, 96 e 192 kg ha-1 de K na forma de cloreto de K. A resposta ao N foi linear e positiva em um dos quatro anos observados. O nutriente diminuiu o tamanho dos frutos, mas não influenciou a qualidade do fruto avaliada pela porcentagem de suco, pelos sólidos solúveis totais, pela acidez total e pela relação sólidos/acidez. Foram observados efeitos positivos do P na produção, na porcentagem de suco e na relação sólidos/acidez. O K aumentou a produção, o tamanho dos frutos e a acidez, mas diminuiu a relação sólidos /acidez.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSobral, Lafayette FrancoSouza, Luiz Francisco da SilvaMagalhães, Antônia Fonseca de JesusSilva, José Unaldo BarbosaLeal, Maria de Lourdes Silva2000-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5758Pesquisa Agropecuaria Brasileira; v.35, n.2, fev. 2000; 307-312Pesquisa Agropecuária Brasileira; v.35, n.2, fev. 2000; 307-3121678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5758/2862info:eu-repo/semantics/openAccess2010-07-30T18:20:06Zoai:ojs.seer.sct.embrapa.br:article/5758Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-30T18:20:06Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
