Investigation of Energy Technology Gap Ratio of Main Crops in Sari city

The aim of this study was to investigate of energy technology gap ratio of main crops in Sari city in 2016. The energy technical efficiency and energy technology gap ratio indices were computed using three approaches; group frontier stochastic production function, pooled frontier stochastic production function and the metafrontier function. Data were collected from Agriculture Jihad Organization of Mazandaran. The results showed that in case of filling the gap between other units and units of efficient products, whit no change in technologies the average amount of energy production for soybeans, canola, alfalfa, barley, wheat and rice could be 19, 23, 35, 33, 39 and 28 percent increase. The results also showed that highest energy technology gaps ratio for the products studied was related to soybean (0.81) and canola (0.67). Thus it is suggested that researchers and policymakers should be more attention about environmental goals, especially ETGR to sustainable use of energy consumption to at least one of the goals in optimization of cropping pattern.
