Investigation of Factors affecting on Technical inefficiency of garlic producers:A case study in Hamedan province

Hamedan province with more than 2000 hectares of garlic growing areas ranks first in Iran. About 62 % of garlic of Iran is produced in this province. The main purpose of this study was to measure the level of technical efficiency of garlic producers.A sample of 148 producers in the main garlic growing areas of Bahar and Hamedan was selected by two stage cluster sampling method. Data were then collected through interviews for farming year of 2000-2001.Technical efficiency of garlic producers were estimated using transcendental stochastic frontier production functions, Also, effects of various social and economical factors were then studied on the level of producers technical efficiencies. Based on the results of this study, it was found that average technical efficiency for garlic growers was 74%. There is much discrepencies between technical efficiency of the best garlic producers with that of the others. Therefore, it is possible to increase production without any major change in technology and used resources, thus decreasing the discrepency between the best and the other producers. Production increase potential have been 26 percent.The main social-economic factors affecting the technical inefficiency of garlic producers have been educational levels,garlic growing area, owner ship of land, number of land units under garlic cultivation. Age of farmer, farmer’s job and experience.
