Cowpea farmers in sub-Saharan Africa obtain low yields; sole cropping system with the use of improved technologies can yield 1,500-2,000 kg/ha of cowpea. However, 200-500 kg/ha yield is obtained by smallholder farmers. It is a multipurpose crop and despite its importance, high level of inefficiency in its production persists. Therefore, the determinants of efficiency in cowpea production were analyzed; the decline in cowpea yield in the study area was attributable to several socioeconomic variables. Multistage sampling technique was used to select 70 cowpea farmers from the study area. Primary data was collected using structured questionnaires. Descriptive statistics and stochastic frontier production function were the analytical techniques adopted. The results indicated that the socioeconomic characteristics of the respondents significantly affected cowpea production. The mean technical efficiency index was 0.59. Furthermore, the stochastic frontier analysis revealed that coefficients of farm size (0.297), labour (0.394), quantity of seed (0.433) and agrochemicals (0.057) were all positive and statistically significant. Also, the inefficiency model revealed that the coefficients of household size (-0.284), education (-0.493) farm experience (-0.402), extension contact (-0.45) and access to credit (-0.255) were negative but statistically significant Thus, the significant variables were the determinants of technical efficiency in cowpea production. The identified constraints adversely affected farm productivity and efficiency. Formation of cooperatives, adoption of measures that improve access to agricultural credit, agro-services centers, input supply, technology transfer and subsidies; extension services, information exchanges and market linkages are recommended to mitigate technical inefficiency in cowpea production among smallholder farmers.
