Integrated evaluation of emergy, energy and economic for different cropping systems in Barley

In order to compare of the Barley crop production systems in terms of energy use efficiency, energy productivity, and cost-benefit ratio to the amount of Renewable and Non Renewable energy is consumed in Farashian an field survey was conducted in 2016. For the purposes of this review, data from 4 (Small area, intermediate area, large area, very large area) Barley farms used for filling in questionnaires were collected through face to face conversations. The result showed that the highest energy input in Barley farm large area production system. 59536/99 MJ, the highest energy output in Barley production system 51450 MJ, the highest energy use efficiency in Barley farm Small area production system 0.85 . The biggest share of all energy in the system assigned to the .electrical energy whereas seed energy has the lowest share of all energy .In total, the survey of index showed that Barley production system is more sustainable
