Resumo: The potential of the Brazilian Northeast coastal tablelands for corn production and the adaptability and stability of sixteen corn cultivars were evaluated at thirteen environments of this region in 1994/95 on a randomized block design experiment with three replications. The large potential of this coastal strip for corn production was evidenced by the obtained yield, highlighting the hybrids, on the coastal tablelands of Piauí, Sergipe and Bahia States, where corn would become a major crop option for the growers. Pooled variance analysis showed significant difference for environments and cultivars, and the interactions environment x cultivar, which were inconsistent. Hybrids had better adaptation than varieties and populations; they are recommended for higher input situations. The AG 510 hybrid showed good adaptation to low and high input conditions, and therefore is recommended for both situations. The BR 5011, BR 5028, BR 106 and BR 5033 varieties had reasonable yields and are suitable for small and medium corn growers.

As produtividades médias alcançadas, especialmente com os híbridos, mostraram o grande potencial dessa faixa costeira do Nordeste para a produção do milho, sobressaindo os tabuleiros costeiros do Piauí, Sergipe e Bahia, onde o milho poderá se tornar uma grande alternativa para os produtores. A análise de variância conjunta mostrou diferenças entre os locais e as cultivares, e a inconsistência das cultivares em face das variações ambientais. Usou-se o método de Cruz et al. para atenuar o efeito da interação cultivares x ambientes, de modo a permitir uma recomendação com mais segurança. Os híbridos mostraram melhor adaptação que as variedades e populações, e são recomendados para exploração em ambientes mais tecnificados. O AG 510, por mostrar adaptação em ambiente desfavorável, é também recomendado para esta condição. As variedades BR 5011, BR 5028, BR 106 e BR 5033, de bons rendimentos, constituem alternativas importantes para pequenos e médios produtores de milho.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSantos, Manoel Xavier dosLeal, Maria de Lourdes da SilvaPacheco, Cleso Antonio PatoTabosa, José Nildo1999-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5561Pesquisa Agropecuaria Brasileira; v.34, n.12, dez. 1999; 2225-2234Pesquisa Agropecuária Brasileira; v.34, n.12, dez. 1999; 2225-22341678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5561/2752info:eu-repo/semantics/openAccess2010-06-29T16:28:34Zoai:ojs.seer.sct.embrapa.br:article/5561Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-06-29T16:28:34Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
