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 |
