Resumo: Plant density response of corn besides influenced by hybrids traits, soil fertility level and water availability, could also vary with sowing date, since it affects plant growth and development. With the objective of determining the most adequate plant density of corn hybrids with high potential grain yields, in three sowing dates, in relation to grain yields, yield components and other agronomic traits, four experiments were conducted in the state of Rio Grande do Sul, Brazil, with complementary irrigation. The treatments were composed by four hybrids (Pioneer 3063, Pioneer 3207, XL 212 and Cargill 901), four plant densities (50, 70, 90 and 110,000 pl/ha) and three sowing dates (August, October and December). There was no response to plant density of corn hybrids tested at sowing dates of August and December. The increase in plant density was beneficial only in the sowing date of October, when the highest grain yield with 70,000 pl/ha was obtained in two growing seasons, out of regard to the hybrids tested.

Com o objetivo de determinar a densidade ótima de planta em híbridos de milho com elevado potencial de rendimento de grãos, em três épocas de semeadura, com relação a rendimento de grãos, componentes do rendimento e outras características agronômicas, foram feitos quatro experimentos na região fisiográfica da Depressão Central do Rio Grande do Sul, município de Eldorado do Sul, com suplementação hídrica por aspersão. Os tratamentos constaram de quatro híbridos (Pioneer 3063, Pioneer 3207, XL 212 e Cargill 901), quatro densidades de plantas (50, 70, 90 e 110.000 pl/ha) e de três épocas de semeadura (agosto, outubro e dezembro). Não há resposta à densidade de plantas dos híbridos de milho testados nas épocas de semeadura de agosto e dezembro. O aumento na densidade de plantas somente foi vantajosa na semeadura de outubro, quando se obtiveram maiores rendimentos de grãos na densidade de 70.000 pl/ha, independentemente do híbrido avaliado, nas duas estações de crescimento.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirada Silva, Paulo Regis FerreiraArgenta, GilbarRezera, Fabiana1999-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5205Pesquisa Agropecuaria Brasileira; v.34, n.4, abr. 1999; 585-592Pesquisa Agropecuária Brasileira; v.34, n.4, abr. 1999; 585-5921678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5205/2397info:eu-repo/semantics/openAccess2010-07-05T13:08:22Zoai:ojs.seer.sct.embrapa.br:article/5205Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-05T13:08:22Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
