Energy Analysis of Sugarcane Production in Plant Farms A Case Study in Debel Khazai Agro-industry in Iran

摘要

The aim of this study was to examine direct and indirect input energy in per hectare in sugarcane production alone in plant farms. The study was performed in Debel khazai Agro-Industry situated in southern region of Iran. Total energy expenditures were 148.02 GJ ha~(-1) and energy output was 112.22 GJ ha~(-1) in plant farms. The output/input energy ratio was 0.76. The energy intensity lies about 1.59 MJ kg~(-1) and is one of the highest among sugarcane producing countries. Irrigation is the most energy consuming operation with about 43% of total energy inputs. Electricity, fertilizers, fuel and machinery are the main energy inputs. The influence of the different inputs is discussed and practical measures for energy saving and environmental conservation based on energy analysis are discussed.
