Resumo: The use of phosphate fertilizers as coated polymers reduces phosphorus losses that occur by adsorption of P to soil particles, thereby providing this essential nutrient for a longer period. The objective of this study was to evaluate the effect of phosphorus doses applied as conventional monoammonium phosphate or as coated polymers on corn grown in a clayey Oxisol, in the Cerrado region. The experiment was conducted in Selvíria - MS, located at 22°22? S and 51°22? W. The experiment was laid out in a randomized block design arranged as a 4 × 2 factorial, with four doses of P2O5 (0, 50, 100, and 150 kg ha-1) and two sources of phosphorus (monoammonium phosphate (MAP) and monoammonium phosphate coated polymers). The experiment was conducted under no-tillage system during the cropping seasons in 2008/09 and 2009/10. The MAP and MAP-coated sources did not differ in most of the yield components in either of the two seasons. We found a quadratic function adjustment for P doses up to 117 and 98 kg ha-1 of P2O5 for P concentration in leaf tissue and grain yield in the 2008/2009 crop, respectively. We also obtained a quadratic function adjustment for P rates for grain yield and number of plants, up to 118 and 113 kg ha-1 of P2O5, respectively, in the 2009/2010 harvest.

Neste contexto, objetivou-se avaliar o efeito de doses de fósforo usando o monoamônio fosfato convencional e o revestido por polímeros na cultura do milho em solo da região de Cerrado. O experimento foi conduzido em Selvíria – MS, com coordenadas geográficas de 20º22' de latitude S e 51º22' de longitude O, num Latossolo Vermelho distrófico de textura argilosa. O delineamento experimental foi o de blocos ao acaso, dispostos em esquema fatorial 4x2, sendo 4 doses de P2O5 (0, 50, 100, e 150 kg ha-1) e 2 fontes de fósforo (monoamônio fosfato e monoamônio fosfato revestido por polímeros). O experimento foi conduzido sob sistema plantio direto nas safras de 2008/09 e 2009/10. As fontes MAP e o MAP revestido não diferiram na maioria dos componentes produtivos nas duas safras. Houve ajuste em função quadrática para doses de P na concentração de P foliar e produtividade de grãos na safra de 2008/2009, até a dose de 117 e 98 kg ha-1 de P2O5, para a concentração de P no tecido foliar e produtividade de grãos, respectivamente, e ajuste em função quadrática para doses de P na produtividade e número de plantas, até 118 e 113 kg ha-1 de P2O5, respectivamente, na safra de 2009/2010.UEL2018-02-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3032810.5433/1679-0359.2018v39n1p99Semina: Ciências Agrárias; Vol. 39 No. 1 (2018); 99-112Semina: Ciências Agrárias; v. 39 n. 1 (2018); 99-1121679-03591676-546Xreponame:Semina.
