ENERGY EFFICIENCY ANALYSIS OF COTTON PRODUCTION IN TURKEY: A CASE STUDY FROM AYDIN PROVINCE
Özet
The purpose of this study is to make an energy efficiency analysis of cotton production during the production season of 2013 in Aydm province of Turkey. In order to determine the energy input-output of cotton, data provided by Aydm-Nazilli Cotton Research Institute have been availed of. The energy input and output in cotton production have been calculated as 29138.11 MJ ha(-1) and 56050 MJ ha(-1), respectively. Energy inputs consist of 38.65 % (11262 MJ ha(-1)) diesel fuel energy, 36.94 % (10764 MJ ha(-1)) chemical fertilizers energy, 9.05 % (2637.36 MJ ha(-1)) machinery energy, 8.65 % (2520 MJ ha(-1)) irrigation energy, 2.85 % (831.63 MJ ha(-1)) human labour energy, 2.64 % (769.12 MJ ha(-1)) chemicals energy and 1.21 % (354 MJ ha(-1)) seed energy. Energy efficiency, specific energy, energy productivity and net energy in cotton plant production have been calculated as 1.92, 6.13 MJ kg(-1), 0.16 kg MJ(-1) and 26911.89 MJ ha(-1), respectively.
