Farm profit inefficiency in yam production in Imo State, Nigeria was estimated using stochastic translog profit frontier model. The mean output of yam producers was 10.3tons/ha, while the mean level of profit inefficiency was 63.7 percent with a wide range of 23.41 – 94.23 percent. Mean loss of profit was N76061 per hectare. Major determinants of profit inefficiency were farm size, access to credit, education, family labour use, extension contact and farming experience. Opportunities still exist to reduce profit loss and inefficiency in yam production in the study area if these factors are given the desired attention.
