Resumo: Due to the short period of nutrient assimilation and to the intense metabolism, the sweet corn presents higher nutritional requirements than the common green corn. Sweet corn cultivation is not compatible with acid soils and shows an increasing yield response to phosphorus, nitrogen and zinc applications. With the purpose of verifying sweet corn nutritional requirements, this investigation was carried out in a greenhouse limed and up to 70% base-contented soil using the following varied levels of Zn (Zinc sulphate) 0.0; 0.8; 1.6 and 3.2ppm and P (bicalcic phosphate) 0.75 and 150ppm. Thirty-three days after seeding, the sweet corn aerial part was evaluated in terms of dry matter yield. The 3.2ppm Zn level presented the highest dry matter yield. Dry matter yield increased with the progressive P concentration in the soil. No significant interaction between Zn and P and sweet corn dry matter accumulation was detected.

Em razão do curto período de assimilação de nutrientes e do intenso metabolismo, o milho-doce apresenta maiores exigências nutricionais que o milho-verde comum. A cultura do milho-doce é intolerante a solos ácidos e apresenta resposta crescente de rendimento às aplicações de fósforo, nitrogênio e zinco. Com objetivo de verificar as exigências nutricionais do milho-doce, realizou-se um trabalho em casa de vegetação, onde se variaram os níveis de zinco e fósforo. O solo foi corrigido com calcário e o teor de bases elevado para 70%. Os níveis de Zn (sulfato de zinco) utilizados foram 0; 0,8; 1,6 e 3,2ppm e P (fosfato bicálcico) foram 0,75 e 150ppm. Após 33 dias do plantio, a parte aérea do milho-doce foi avaliada quanto ao rendimento de matéria seca. O nível de 3,2ppm de Zn apresentou maior rendimento de matéria seca. O rendimento de matéria seca cresceu com o aumento da concentração de P no solo. Não houve interação significativa entre o Zn e o P e o acúmulo de matéria seca do milho-doce.Universidade Estadual de Maringá2008-07-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/435910.4025/actasciagron.v20i0.4359Acta Scientiarum.
