Cowpea (Vigna unguiculata (L.) Walp.) is one of the main sources of nutrients for a large part of the population. To increase your income, there is a need for proper management. This study aimed to evaluate yield components of the cowpea cultivar Aracê subjected to two levels of organic fertilization and three management of the natural vegetation of the savannah of Roraima. The experiment was set up in the experimental area of CCA/UFRR, in Boa Vista, Roraima. The experimental design was a randomized block design in a 3×2 factorial scheme, with four replications. The first factor consisted of the management of the natural vegetation: glyphosate application and cutting or not of the natural vegetation. The second factor consisted of the application or not of cattle manure. Yield components were plant height, number of trifoliate leaves, percentage of normal pods, pod length, number of grains per pod, 100-grain weight, sample grain index, total grain index, and final stand. Organic fertilization with 2 L m-2 of manure increased cowpea production. The management with vegetation cutting in areas with organic fertilization increased the final stand of cowpea plants. The desiccation of natural vegetation with glyphosate was the management that had the highest cowpea production.
