The purpose of this study was to measure the technicalefficiency of canola farmers and determine the underpinningfactors. Required data were collected using stratified randomsampling method and questionnaire survey. In this context, 157canola farmers from Tabriz County, Iran, were asked to fill outthe questionnaire in 2012-2013 growing season. The technicalefficiency was evaluated using stochastic frontier approach. Theresults of inputs production elasticity indicated that all inputswere consumed in economic area. In addition, the highest (0.504)and lowest (0.095) elasticity rate was related to water consumptionand education level, respectively. The estimated technical efficiencydemonstrated that the highest and lowest technical efficiencieswere 25 and 95% with an average of 80%. It should be noted thatthe highest efficiency was observed in the farms with the areacovering 3-4 hectares. Furthermore, the estimated inefficiencymodel indicated that education level, training course number,and cultivated area negatively affected the inefficiency. Bycontrast, age of farmer had a positive effect on inefficiency. Asthe results show, educating and training farmers for the optimumuse of inputs as well as improving their knowledge as to promoteagricultural products should be taken into account.
