Abstract :

The main purpose of this study was to evaluate the efficiency and technological gap ratio (TGR) of different rice cultivars in Guilan province For this purpose, metafrontier method was used to determine the TGR. The statistical population of the study was all rice farmers in Guilan province in 2017. Sample size was selected by stratified sampling method. The results showed that the mean technical efficiency range of different rice varieties was between 76% and 93%. In fact, if the gap between the farmers in the study is filled. In fact, the average yield of the Hashemi, Domsiah, Ali Kazemi, Jamshidjo, Shiroudi and Khazar could be 47, 7, 23, 12, 8 and 15 present increases respectively. The results also showed that the highest technological gap ratio for the studied varieties was related to Hashemi (0.96) and the lowest technology gap ratio was related to Khazar (0.45). Based on the results income, mechanization index, farmer's main occupation, ownership, experience and land size have a positive and significant effect on farmers' technical efficiency.
