In Ghana, statistics indicate that women account for about 70% of total food production and are the most important actors in the food chain which begins from the farm production, market and intra household distribution of food. They play a lead role in post-harvest activities such as shelling of grains, storage, processing and marketing. They are also becoming increasingly visible in farm tasks which traditionally have been designated as male preserve. Despite the increasing central role of women in food production, they have much more limited access to resources than their male counterparts especially in the areas of education, land, agricultural extension services and access to credit, all of which combine to restrain their ability to increase productivity. This study was therefore undertaken toexamine the technical efficiency of male and female vegetable farmers in the Kumasi Metropolis using the stochastic production frontier model. Female vegetable farmers were found to be producing at high levels of inefficiency. The predicted efficiencies differed substantially from between 2 and 85 percent, with mean efficiency of 24 percent. The low mean efficiency index is an indication of inefficiencies in resource use. Also, female headed farms recorded a mean technical efficiency of 16.5 percent with a range between 2 and 66 percent. The male headed farms, on the other hand, showed a mean technical efficiency of 30.8 percent, and a range between 2 and 85 percent. The results imply that on the average, female vegetable farmers were relatively technically inefficient than their male counterparts. The paper concludes that since women farmers contribute immensely of domestic food supply in Ghana, it is important that efforts be made to build their capacity to produce efficiently.
