Abstract :
The aim of this study was to calculate the energy parameters in greenhouse cucumber production and efficient and inefficient units in Qazvin province was determined. In this study, questionnaires were distributed set between the greenhouse area. Ask the person to complete the questionnaires . A total of 25 units was Dadhbrdary greenhouse production. To determine the efficiency of greenhouses Data envelopment analysis (DEA) was used. The results showed that the highest energy consumption in greenhouse cucumber production earth energy fuel AS DEFINED IN 64 981 MJ per hectare for the production of energy is consumed. After the highest fuel consumption of all energy-related greenhouse Electricity is 23,841 MJ of energy consumed per hectare. 48/0 cucumber greenhouses for the production of energy, energy efficiency and increased 61/0 kg MJ net energy 4 / 73452- MJ was obtained. Greenhouse 25 provinces, six greenhouse greenhouse cucumber effective and 19 others were ineffective. Average performance is inefficient units 87/0.
