Abstract

Credit constraint (CC) is a crucial factor limiting maize production. Farmers’ cooperative group is the stylish medium for smallholder growers to access fund. Despite this, growers’ efficiency is low, thus, this study examined the effect of credit constraints on co-operators' maize growers’ efficiency in Oyo state. Oyo state Agricultural Development Project (ADP) sample frame was employed. A five- stage sampling procedure was espoused. Intentionally, Oyo state was picked due to the highest number of registered agrarian collaborative societies. One block each from the ADP zones was randomly picked. Two cells were also randomly picked from the blocks. Cooperative societies were randomly picked and also intentional selection of maize planter co-operators proportionate to the size of the registered co-operators. Data were collected with structured questionnaires. Two- hundred co-operator growers were picked in all. Data collected were analysed using t- test, stochastic frontier, and quantile regression α= 0.05. The determinants of maize growers’ efficiency were labour, farm size, fertilizer, and seed. Yields were significantly and appreciatively affected by the farm size and inputs from cooperatives, experience, sex, and dependency ratio, but CC negatively and significantly impacted maize yield. Grounded on the finding’s growers’ cooperatives should be empowered by the government to make agrarian land, modern inputs, and training available to growers.
