Assessment energy, energy balance and economic indices of rain fed farming barley Production in North of Iran
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 11
Abstract
This study analyzed energy use and investigated influences of energy inputs and energy forms on output levels in barley production under rain fed farming in north of Iran. The data were collected from 70 farmers, by questionnaire method. By using of consumed data as inputs and total production as output, and their concern equivalent energy, energy balance and energy indices were calculated. Energy efficiency (energy output to input energy ratio) for seed and straw in this study were calculated 1.91 and 2.04 respectively, showing the affective use of energy in the agro ecosystems barley production. Energy balance efficiency (production energy to consumption energy ratio) for seed and straw in this study were calculated 1.19 and 0.92 respectively, showing the affective use of energy in the agro ecosystems barley production. Results economic analysis showed the benefit to cost ratio in the studied farms was calculated to be 1.13.
