Abstract

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.
