Resumo: The objective of this work was to evaluate the NPK influence on yield and oil, proteins and phytochemical contents in sunflower grain and to explore the potential of mathematical model of marginal contributions of fertilization effects. The field experiment was conducted in 33 incomplete factorial model, in two randomized blocks, with 15 parcels for block. The treatments were zero, 30 and 60 kg ha-1 of N, P and K. The achene yield increased with fertilizer doses until 55 kg of N ha-1, 41 kg ha-1of K2O and 46 kg ha-1of P2O5. The achene oil content answered positively to increased K2O and P2O5. Proteins content decreases as K2O rate increases. No influence of the fertilization was observed in concentrations of chlorogenic acid, total sterols and total phosphorus on achene.

O ensaio de campo foi conduzido em um modelo fatorial incompleto 33, em dois blocos casualizados, com 15 parcelas por bloco, onde se empregou os níveis zero, 30 e 60 kg ha-1 de N, P e K. Observou-se aumento de produtividade de aquênios com doses estimadas de até 55 kg de N ha-1, 41 kg ha-1 de K2O e 46 kg ha-1de P2O5. O teor de óleo nos aquênios aumentou com incremento de K2O e P2O5 e o teor de proteínas diminuiu com incremento de K2O. Não foram observadas influências da adubação sobre os teores de ácido clorogênio, esterois totais e fósforo total nos aquênios.UEL2006-07-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/249310.5433/1679-0359.2006v27n4p533Semina: Ciências Agrárias; Vol. 27 No. 4 (2006); 533-546Semina: Ciências Agrárias; v. 27 n. 4 (2006); 533-5461679-03591676-546Xreponame:Semina.
