Using the data from 11 provinces for cotton and 15 Provinces for sugar beet production, the various efficiencies were estimated with Data Envelopment Analysis technique (DEA). The results indicated that the majority of Iranian provinces are not operating efficiently. Regarding to Cotton industry, only four provinces are technically efficient when variable return to scale is assumed. In Sugar Beet industry six provinces are doing well In condition of variable return to scale. When constant return to scale is assumed, the number of provinces, which are efficient, are limited. It can be suggested that with training and teaching of the farmers the efficiency in the country can be improved.
