Investigation of energy efficiency and greenhouse gas emissions of safflower production in terms of environment

This study was carried out to evaluate the energy efficiency of safflower production units using data envelopment analysis technique in Jolgeh district of Isfahan province in 2016. Data were collected from a total of 30 safflower farms using questionnaires and face to face interviews. The results showed that the input and output energy were 30843.1 and 6775.71 megajol/ha, respectively. The highest share of energy consumption was allocated to chemical fertilizers (48.18%), fuel (24.55%) and water (12.44%) respectively. The average technical efficiency, net technical efficiency and efficiency of Safflower product scale were 94.28%, 99.93% and 94.33%, respectively. According to the CCR model, the highest intakes of excessive intake units are related to the inputs of chemical fertilizers, especially urea (58%), diesel fuel (18%), water (12%) and seed consumption (8%). Fuels with 49% and then urea fertilizer with 35% have the largest share in the emissions of greenhouse gases in the production of safflower (Figure 4-16). Therefore, using managed mechanized systems, it is necessary to control the use of machinery to reduce fuel consumption and to reduce the consumption of urea crop by replacing livestock fertilizers in order to reduce the pollution caused by greenhouse gas emissions and pollution of the water resources of the area.This study was carried out to evaluate the energy efficiency of safflower production units using data envelopment analysis technique in Jolgeh district of Isfahan province in 2016.
