Introduction. Within the production systems of the peasant economy in the Caribbean Region, the cowpea (Vigna unguiculata L. Walp) is important given its nutritional quality. There are few studies that inquire about the allocation of production factors by the producer. Objective. To analyze and determine the efficiency of cowpea production in the Caribbean producing regions of Colombia. Materials and methods. Between 2018 and 2020, the study was conducted using the information applied to 31 productive units in the producing regions of the departments of Cordoba, La Guajira, and Cesar in a randomly selected sample using the simple random sampling method. A structured survey was applied to the sample on data on inputs used in production such as labor, seed, fertilizer. Descriptive statistics, dispersion measures, correlation, and regression analysis were calculated, and for the purpose of evaluating the efficiency and contribution of each factor to production, a Cobb-Douglas econometric model was formulated. Results. Information was generated on the contribution of each factor makes to production, where seed and fertilizer stand out as those with the greatest contribution. Conclusions. The farmer was efficient because there was a direct relationship between the increase in inputs and the quantities produced, in addition, the technology gap is narrow of the order of 8 %, with yields on an increasing scale due to the direct relationship between the increase in inputs and the increase in product.
