Cities were include Neka, Behshar, Sari and Joybar. The necessary information through interviews with farmers is obtained. For estimating the production function, Transcendental function is used. Among various estimates of the stochastic frontier approach has had the best results. The results showed, there is a significant relationship between dependent variable (yield in unit area) and the number of labor, hours of plowing, seed amount, the amount of urea, phosphate, potash fertilizer and herbicide and farm size also results showed that the mean technical, allocative and economic efficiency colza producers have respectively, 75%, 56% and 42%.
