Abstract

The objectives of this study were to determine the energy consumption and evaluation of relationship between inputs and output for wheat production in Karaj region, Iran. For this propose data were collected from 60 wheat farms using a face to face questionnaire. The results revealed that total energy input for wheat production was found to be 31188.25 MJ ha-1 that the share of non-renewable energy form (89%) was more than renewable energy form (11%). Electricity has the highest share by 38.25% followed by total fertilizers and diesel fuel. Energy use efficiency, energy productivity, and net energy were 3.03, 0.21 kg MJ-1, and 65012.08 MJ ha-1, respectively. The regression results revealed that the contribution of energy inputs on crop yield (except for diesel fuel energies) was significant. Machinery energy was the most significant input (0.798) which affects the output level. It indicates that a 1% increase in the energy machinery input led to 0.798% increase in yield in these circum

Conclusion

The aim of this study was to analyze impact of a particular energy input level on wheat yield in Karaj region, Iran. Based on the results of the investigations, the following conclusions were drawn: Total energy input for wheat production was found to be 3246.53 MJ ha-1 and energy output was calculated as 96200.33 MJ ha-1. Electricity showed as the most energy consuming input followed by chemical fertilizers and diesel fuel. Energy use efficiency, energy productivity, and net energy were 3.03, 0.21 kg MJ-1, and 65012.08 MJ ha-1, respectively. The ratios of non-renewable energy are more than renewable energy (89% and 11%). Therefore, it is clear that wheat production depended on non-renewable energy consumption. The impact of energy inputs could have positive effect on yield (except for diesel fuel energies). It was concluded that additional use of machinery, and increasing mechanization level, would result more yield in the area.
