Resumo: The objective this work was evaluate the commercial quality of grains of differents commercial corn hybrids as a function of grain moisture content during the harvest. The work was conducted in Astorga – PR, during the autumn/winter harvest of 2007 and the summer harvest of 2007/2008, evaluated three hybrids for harvest. The corn grain samples were collected in five distinguished periods and also in five replications, being underwent to moisture content determination at an oven heated to 103 ± 1 ºC for 72 h. The samples were passed through metal sieves of circular sieve of 4.76 mm in diameter and then the waste is manually separated portions of the impurities, broken grain and grain damaged by insects. The data were submitted to analyses of variance and regression under a arrangement completely randomized design, The percentages of impurities were higher in crop moisture content higher. While the percentage of broken grains were lower, regardless of the hybrid and the trial period. The percentage of grain damaged by insects raised linearly with the reduction of moisture in corn grains, in all hybrids and in two evaluation periods. The moisture content between 22.0% and 26.0% (w.b.) proportionated the best quality of the corn grain, considered this humitidy band as the best moment to harvest grains.

O trabalho foi conduzido em Astorga – PR, durante o período da safrinha de 2007 e da safra de verão de 2007/2008, sendo três híbridos avaliados em cada período. As amostras de grãos foram colhidas em cinco épocas distintas com cinco repetições e submetidas à determinação do teor de água pelo método da estufa a 103 ± 1 ºC por 72 h. Posteriormente, as amostras foram passadas por peneiras metálicas de crivo circular de 4,76 mm de diâmetro e, em seguida, os resíduos foram separadas manualmente nas porções de impurezas, grãos avariados e grãos carunchados. Os resultados obtidos foram submetidos à análise de variância e de regressão sob o delineamento inteiramente casualizado. Os percentuais de impurezas foram maiores nos teores de água de colheita mais elevados, enquanto que os percentuais de grãos avariados foram menores, independente do híbrido e do período avaliado. O grau de infestação se elevou linearmente com a redução do teor de água nos grãos de milho, em todos os híbridos. Os teores de água entre 22% e 26% (b.u.) proporcionaram melhor qualidade física e sanitária dos grãos de milho, considerando esta como a faixa ideal de teor de água para a colheita dos grãos de milho.UEL2012-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/658410.5433/1679-0359.2012v33n3p911Semina: Ciências Agrárias; Vol. 33 No. 3 (2012); 911-920Semina: Ciências Agrárias; v. 33 n. 3 (2012); 911-9201679-03591676-546Xreponame:Semina.
