Resumo: In an experiment with sixa replicates, conducted in Lavoura Seca Farm (Quixadá, CE, Brazil), the influence of nine phenologic characteristics on the final yield of cowpea ( Vigna unguiculata (L.) Waip), cultivar Pitiúba, was studied, using, for each replicate, five plants randomly chosen. The technique of path coefficient was applied to investigate both direct and indirect effects of the different characters studied on the yield. The results showed that in this cultivar a high, direct and positive correlation exists between the number of pods present in each plant and the seed production.

Walp), sobre a produção final, tornando-se, em cada repetição, cinco plantas ao acaso. Utilizou-se a técnica do coeficiente de caminhamento para averiguar os efeitos diretos e indiretos dos diferentes caracteres estudados sobre a produção. Os resultados evidenciaram que há uma alta correlação, direta e positiva, entre o número de vagens presentes em cada planta e a produção de grãos dessa cultivar.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraOliveira, Francisco José deVarejão-Silva, Mário AdelmoGomes, Marcelo Jota2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13553Pesquisa Agropecuaria Brasileira; v.25, n.7, jul. 1990; 1055-1064Pesquisa Agropecuária Brasileira; v.25, n.7, jul. 1990; 1055-10641678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13553/7696info:eu-repo/semantics/openAccess2014-04-17T14:34:50Zoai:ojs.seer.sct.embrapa.br:article/13553Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T14:34:50Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
