West Azerbaijan province is the major producer of sugar beet in Iran. To reach the goals of self-sufficiency in the country and competitiveness in the market, increasing the production of sugar beet in this province through enhancing the efficiency of producers could have an important contribution. The purpose of this research was to measure the efficiency of sugar beet producers in West Azerbaijan. By selecting a random sample of sugar beet producers in this province, interviewing, and the questionnaire, the necessary data was collected. To measure the efficiency of sample producers, Frontier stochastic parametric approach was used. The results showed that mean efficiency of sample sugar beet producers was 69.5 percent, which ranged from 15.9 to 100 percent. The results indicate that with the available resources and technology there is a high potential to increase sugar beet production in the province. To determine policy measures for enhancing the efficiency of sugar beet producers there is a need for more detailed study, especially on the factors influencing the efficiencies.
