An input-output energy analysis in wheat production in Çarşamba district of Samsun province
The objective of the present study was to evaluate the efficiency of energy use in wheat production in Çarşamba District of Samsun Province. In this study also aimed to analyse the wheat production costs and the profitability. The study was carried out in 54 wheat producers using a questionnaire. The farms were chosen by random sampling method. Total energy consumption in wheat production was found 35737.13 MJ ha-1. The highest input energy item was determined as diesel (44.61%). Chemical fertilizers (23.54%) mainly nitrogen, water for irrigation (10.58%), seed (10.11%), machinery (9.86%), chemicals (0.92%) and labor (0.38%) followed the diesel. Energy output was calculated as 84427.33 MJ ha-1. Energy use efficiency, spesific energy, energy productivity and net energy for wheat production were determinated 2.36, 8.96 kg MJ-1, 0.112 kg MJ-1 and 48690.20 MJ ha-1, respectively. The benefit-cost ratio was found to be 0.64.
