Aim of this study was to determine resource use efficiency in yam production in Yakurr local government area of Cross River State, Nigeria. The study covered 3 villages that were purposely selected. The villages are Mkpani, Agoi-Ibami and Agoi-Ekpo. Data were obtained through a structured questionnaire administered to 135 randomly selected yam farmers. 130 questionnaires were retrieved and used for analysis.The stochastic frontier production function model was used for the analysis. The result was used to determine their technical, allocative and economic efficiencies. Two of the variables, planting material (x 1) and farm size (x 2) were highly significant at 1% level of probability and labour (x 3) was significant at 10% probability level.Allocative efficiency revealed that planting material and farm size were underutilized while labour and capital were over-utilized. The economic efficiency differed subsequently among the farmers ranging from between 0.089 and 0.861 with mean efficiency of 0.36. The low mean economic efficiency is an indication of inefficiency in resources used by yam farmers in the study area. The study recommended that production inputs especially farm size be increased by yam farmers and improved technology be adopted to increase yam production in the study area.
