dc.description	The objective of this work was to evaluate seventeen lineages and three cultivars of cowpea [Vigna unguiculata (L.) Walp.] with semi-prostrate port, in relation to grain yield and components related to the cycle and the plant architecture under dry and irrigated cultivation, in Teresina County, Piauí State, Brazil. Two experiments were conducted with a completely randomized desing with twenty treatments and four repetitions. The MNC99-541F-15, TE96290-12G, MNC99-547F-2, MNC99-510F-16 and TE97-304G-12 lineages and BRS-Marataoã and BR-17 Gurguéia cultivars showed the largest yields under dry cultivation. From another standpoint, the MNC99-542F-5, TE96-290-12G, TE97-304G-12, MNC99-541F-18, TE97-309G-24, MNC99510F-16, TE97-304G-4, MNC99-547F-2, MNC99-510F-16 lineages and the BRS Paraguaçu cultivar stood out in the irrigated cultivation. The lineages TE96-290-12G, MNC99-510F-16 and TE97-304G-4 showed good yields levels in both cultivation systems. These results, besides the identification of genotypes with the largest productive potential, suggest that it is possible to select genotypes to dry and irrigated cultivation.	en-US
dc.description	O objetivo deste trabalho foi avaliar dezessete linhagens e três cultivares de feijão-caupi [Vigna unguiculata (L.) Walp.] de porte semi-prostrado, quanto ao potencial de rendimento de grãos e dos componentes relacionados ao ciclo e à arquitetura da planta em cultivo de sequeiro e irrigado, em Teresina-PI. Foram conduzidos dois experimentos com o delineamento experimental em blocos completos casualizados, com vinte tratamentos e quatro repetições. As linhagens MNC99-541F-15, TE96290-12G, MNC99-547F-2, MNC99-510F-16 e TE97-304G-12 e as cultivares BRS-Marataoã e BR-17 Gurguéia apresentaram as maiores produtividades em cultivo de sequeiro. Por outro lado, as linhagens MNC99-542F-5, TE96-290-12G, TE97-304G-12, MNC99-541F-18, TE97-309G-24, MNC99510F-16, TE97-304G-4, MNC99-547F-2, MNC99-510F-16 e a cultivar BRS Paraguaçu se destacaram no cultivo irrigado. As linhagens TE96-290-12G, MNC99-510F-16 e TE97-304G-4 apresentaram bons níveis de produtividade em ambos os sistemas de cultivo. Esses resultados além de identificarem os genótipos de maior potencial produtivo sugerem que é possível selecionar genótipos para cultivo de sequeiro e irrigado.
