Data were collected through interviews during farming year of 2001-2002.Technical efficiency of sugar beet producers were estimated using Cobb-Douglas statistics frontier production functions. Also, the effects of various social and economical factors on the level of producers technical efficiency were studied. According to the results of this study, average technical efficiency for sugar beet growers of Hamedan and Malayer was estimated 0.73 and 0.70, respectively. There were much discrepancies between technical efficiency of the best sugar beet producers with that of the others. The production can be increased up to 27 and 30 percent in mentioned regions without any major change in technology and available resources, and only by decreasing the discrepancy between the best and the other producers.
