Abstract :
The aim of this study was to evaluate the energy index in the production of pistachio in the garden of Qazvin and determine the efficiency of the units in the province. For this study questionnaires were distributed set between farmers and in-person interviews were taken from the garden owners. A total of 20 units were taken pistachio production data. In order to determine the effectiveness of pistachio orchards of data envelopment analysis (DEA) was used. The results showed that the highest share of energy consumption for producing Energy fertilizer per hectare , AS DEFINED 6/16201 MJ of energy is consumed to produce the product. After fertilizer highest energy consumption in pistachio orchards irrigation energy that is consumed 72/10185 MJ energy per hectare. pistachio energy production 0/31 , energy efficiency 0/026 MJ /kg and increasing net energy of -29327/81 MJ , respectively. Pistachio orchards of 20 units of study in the province 5 of efficient and inefficient units were 15. Average performance inefficient units were 867 / 0.
