Resumo: An experiment was carried out in 1981, at the Experiment Station of the "Instituto Agronômico de Campinas" (IAC), in Pariquera-Açu, SP, Brazil, in order to maximize the obtention of green corn, through the improvement of some cultural practices. The estudied variables were as follows: three varieties (IAC-Phoenyx 1817, Cargill 742 and Agroceres 351 B);three plowing spacing rows (1.2; 1 and 0.8 m; and three fertilization levels (50-40-20; 62.5-50-25 and 75-60-30). A randomized block design with five replications was used in split plot arrangement. Varieties and fertilization levels were settled in a factorial 3 x 3 in the subplots. The single hybrid Cargill 742 showed the highest yield. The best results for the three varieties were found using the spacing of 0.8 m between rows and the fertilization level of 62.5-50-25. There was no significant interaction between variety x spacing, variety x fertilization levels and spacing x fertilization levels. Cargill 742 showed the smallest number of lesions of Helminthosporium turcicum Pass.

Através de um delineamento em blocos ao acaso, com parcelas subdivididas, foram testados, com cinco repetições, os seguintes tratamentos: três espaçamentos entre linhas (1,2; 1 e 0,8 m); um fatorial 3 x 3, constituído por três cultivares (IAC - Phoenyx 1817, Cargill 742, e Agroceres 351 B), e três dosagens de adubação NPK (50-40-20, 62,5-60-25 e 75-60-30) como subparcelas. A cultivar Cargill742 apresentou um rendimento médio superior ao das demais. Para as três cultivares, o espaçamento de 0,80 m e a dosagem de 62,5-50-25, foram os que proporcionaram maior produtividade. As interações cultivares e espaçamentos, cultivares x dosagens e espaçamentos x dosagens não foram significativas. Verificou-se também a ocorrência de Helminthosphorium turcicum Pass., mostrando-se com maior grau de resistência, a Cargill 742, em comparação com as demais cultivares.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraIshimura, IssaoSawazaki, EduardoIgue, ToshioNoda, Massaharu2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15381Pesquisa Agropecuaria Brasileira; v.19, n.2, fev. 1984; 201-206Pesquisa Agropecuária Brasileira; v.19, n.2, fev. 1984; 201-2061678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15381/9264info:eu-repo/semantics/openAccess2014-04-16T19:16:05Zoai:ojs.seer.sct.embrapa.br:article/15381Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:16:05Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
