Besides of these variables, amount of onion and animal fertilizer consumption have a significant effect on saffron production in Torbat-e- Heydariyeh. Estimating the nonefficiency function in this town, indicate that age and education have negative and significant effect on technical nonefficiency. In Gonabad, some variables such as age and number of land have significant effect on technical nonefficiency but, in Ghayen, age, education, number of land and nonfarm job have significant effect on it. Average of technical efficiency in Torbat-e- Heydariyeh, Gonabad and Ghayen was calculated about 86, 83 and 84 percent respectively.
