This paper employs a translog stochastic frontier model to examine the profit efficiency of
cocoyam production in Osun State, Nigeria. Farm-level data were collected from a sample of 120 cocoyam
farmers. The average profit efficiency level was 12 percent. The result from the translog frontier profit
function shows that corm and dummy variable for soil are important factors explaining changes in profit.
The result also shows that family size, farm size, mulch and credit contribute negatively to loss of profit
while farming experience tends to increase loss of profit. Loss of profit in cocoyam production can be
reduced significantly by increasing farm size, using of mulch and having better access to credit.
