Technical efficiency evaluation is one of the methods can help researchers to measure producer distance from the best possible product and recognize and study the reasons of the distance. In technical efficiency evaluation we just study effective physical inputs on production and don’t consider Rial’s value of inputs. The best step is determining and evaluation of product function, which in effective inputs can be recognized, and their effects can be clear on production and then we can evaluate technical efficiency using frontier function production. In this research, the average of technical efficiency was %63 that indicates normal position in production. The reason of this difference first is how to grape training which grows mostly in creeping manner, and planting system is usually in furrow. Application of localized placing and animal fertilizer is very effective on grape production. Technical efficiency is low, because of lacking exact information of producers about grape nutrition and not to following mentioned rules and principles.
