The cowpea is a leguminous of great importance for human consumption, providing a source of protein for most of urban population of northern Brazil, therefore the aim of this paper was to evaluate the efficiency of strains of Bradyrhizobium out in association with phosphate and potassium fertilization (PK) in cowpea at the field level in the municipality of Capitão Poço - PA. Two experiments were carried out in randomized blocks with four replications, consisting of five treatments, being two strains of Bradyrhizobium - BR 3262 and BR 3267, a treatment only with PK, another one with NPK in the formulation (10-28-20) and a control. It was evaluated the grain yield, the number of pods and weight of 100 seeds. Fertilization with phosphorus and potassium represented a significant increase in the yield of cowpea, however inoculation with both strains did not increase production.
