Resumo: The levels of maize productivity currently reached in the State of Tocantins, Brazil, are placed below the potential of this crop, due to, among other factors, the lack of knowledge on the best sowing density and row spacing. The present study was carried out with the objective of evaluating the effect of plant distribution on the grain yield, in kg.ha-1. Two maize genotypes (AGN2012 and BRS2020), in two sowing densities (50,000 and 60,000 plants.ha-1), were used, in row spacing of 50 cm, 65 cm, and 80 cm, in Alvorada (TO), in the 2004/2005 growing season. Considering the results, it was possible to observe that the AGN2012 cultivar was more productive than the BRS2020, with significant difference, according to the F test (5% probability), for grain yield. The stalk diameter and plant height increased significantly (p < 0.05), as row spacing decreased. The ear height, diameter, length, and weight of one hundred seeds were not influenced by the evaluated row spacing and density. KEY-WORDS: Density; hybrids; agronomic features.

Os níveis de produtividade do milho, atualmente atingidos no Estado do Tocantins, colocam-se abaixo do potencial da cultura, devido, entre outros fatores, à ausência de conhecimento sobre a melhor densidade e espaçamento de semeadura. O presente trabalho foi realizado com o objetivo de avaliar o efeito da distribuição de plantas sobre a produtividade de grão, em kg.ha-1. Foram utilizados dois genótipos de milho (AGN2012 e BRS2020), em duas densidades de semeadura (50.000 e 60.000 plantas.ha-1), nos espaçamentos de 50 cm, 65 cm e 80 cm, no município de Alvorada (TO), na safra agrícola 2004/2005. Através dos resultados obtidos, pôde-se observar que a cultivar AGN2012 foi mais produtiva que a cultivar BRS2020, ocorrendo diferença significativa, pelo teste F, a 5% de probabilidade, para a produtividade de grãos. As variáveis diâmetro de colmo e altura de plantas aumentaram, significativamente (p < 0,05), à medida que se diminuiu o espaçamento entre linhas. Os componentes altura, diâmetro e comprimento de espiga e peso de cem sementes não foram influenciados pelos espaçamentos e densidades em estudo.
