Cowpea is a crop grown in several Brazilian regions, rich in protein and is one of the most important legumes and even in less favorable edaphoclimatic conditions, it produces satisfactorily. The cultivated area with cowpea in Brazil for the 2017/2018 harvest was approximately 1,440 thousand ha, where the Northeast region had the largest planting area, 404.20 thousand ha. In view of its great importance for the Northeast region and, considering a culture that presents rapid expansion throughout Brazil, it is also considered as another option for export culture. By the other hand, the creation of confined animals grows every year and this growth favors a considerable volume of waste that, if thrown into the environment, can cause damage to that environment. In this sense, the present study aimed to evaluate the behavior of two Creole varieties of cowpea, LA2017 and CB2017, when submitted to three proportions of soil and swine manure, in two cultivation conditions, with and without mulch. Through the observed results it was concluded that, in general, the presence of swine manure increased the weight of seeds by approximately 27% by the treatment composed of 100% swine manure, when compared to 50% swine manure + 50% Ground; The 50% treatment of swine manure + 50% soil increased the weight of pods per plant by 41%; The cultivation system with mulch influenced up to 37% the weight of pods and the number of pods per plant, in favor of LA2017.
