In this paper, Data Envelopment Analysis (DEA) technique was applied for apple (Red and Golden delicious varieties) producers in West Azarbaijan province, Iran (2008-2009). Results showed that the highest share of energy consumption belongs to packaging (57%) and irrigation (16%). Highest share...

Fossil fuel resources are severely limited and their combustion is a major source of environmental pollution. As a result, scientists avidly seek alternatives to fossil fuels, and biomass can be a viable alternative source of energy. Anaerobic digestion is one of way of converting biomass to...

In recent years, growing attention has been given to exergy analysis of drying processes and systems and optimization of drying processes using exergy concept. This research interest is motivated by increasing the price of energies, environmental concerns, world population, decreasing fossil...

This paper studies the energy balance between the input and the output per unit area for garlic in Hamedan province of Iran. In this study, data were collected by administering a questionnaire in face-to-face interviews. Results showed that the highest share of energy consumption belongs to...

This study examines energy consumption of inputs and output used in kiwifruit production, and to find relationship between energy inputs and yield in Mazandaran, Iran. For this purpose, the data were collected from 86 kiwifruit orchards which were selected based on random sampling method. The...

In this study, Data Envelopment Analysis approach was used to analyze the energy efficiency of farmers, to find efficient and inefficient ones and to identify the wasteful uses of energy in kiwifruit production. Moreover, the effect of optimization of energy on improvement of input costs and...

The greenhouse areas in Iran have expanded rapidly and the greenhouse holders have shown a great tendency to cultivation of those crops that used to be cultivated in open fields. Although, greenhouses are intensive in terms of yield and whole year production, they are considered being one of the...
