Fábio José Marqueshttps://repositorio.ifal.edu.br/handle/123456789/1344The cowpea [Vigna unguiculata (L.) Walp] is a nutritionally rich legume, becoming an important food for rural populations. Family Farms in the Northeast region, specifically the Semiarid, cultivate this legume for subsistence, using creole varieties for planting that are adapted to the environmental conditions in which they are inserted. Small farmers often conduct the planting without carrying out the nutritional management of the soil. However, the fertilization of agricultural crops presents high costs for the producer. Therefore, it is necessary to use alternative sources of nutrients. Organic fertilizers are one of the alternatives to the use of these chemical fertilizers, using as an example cattle manure, that is rich in nitrogen and potassium, and that is widely used by small producers. Thus, the objective of this work was to test the productive response of cowpea genotypes under two fertilization managements: organic and conventional. The experiment was conducted at the Federal Institute of Alagoas, Piranhas Campus - IFAL, located in the municipality of Piranhas - Alagoas, from March 2021 to July 2021. The experimental design used was a randomized block design with three replications, in a factorial scheme 4 x 3, where four correspond to the genotypes of cowpea (Corujinha, Manteiguinha, Moita and Canapu, commercial) and three sources of fertilizations (fertilization with cattle manure, mineral fertilization and without fertilization) and three replications, totaling 36 experimental units. When the pods presented characteristics compatible with the harvest point for the production of green beans and dry beans, the harvest was started manually, where the following characteristics were evaluated for the Green Beans: length of green pods (cm) (CVV); number of green pods per plant (NVVP); number of green beans per pod (NGVV); productivity of green beans, where the data were transformed into t ha-1. For dry beans: number of dried pods per plant (NVSP); number of dried beans per pod (NGSV); dry bean yield with subsequent conversion to t ha-1. The collected data were submitted to statistical analysis of variance by the F test, and when significant, the means compared by the Tukey test, at the level of 1% and 5% probability, with the aid of the SISVAR program® version 5.6. Canapu genotype stood out in terms of green and dry bean the production parameters, except in the productivity of dry bean yield, with the Moita variety being the best. The management with mineral fertilization provided the best results and the management without fertilization had better performance when compared to the management with manure fertilization. For green bean yield, the Canapu genotype obtained the best response, with a yield of 1,883.66 kg ha-1 of green beans. For dry bean production, the Moita variety was the best with a yield of 1,203.68 kg ha-1.PorAttribution-NonCommercial-NoDerivs 3.0 BrazilVariedadesManejo nutricionalComponentes de produçãoVarietiesNutritional managementProduction componentsTrabalho de Conclusão de CursoENGENHARIAS
