    DETERMINATION OF ENERGY USE EFFICIENCY OF COTTON PRODUCTION IN TURKEY: A CASE STUDY FROM HATAY PROVINCE
    (Parlar Scientific Publications (P S P), 2019) Semerci, Arif; Baran, Mehmet Firat; Gokdogan, Osman; Celik, Ahmet Duran
    This study aimed at determining the energy efficiency of cotton production in the Hatay region of Turkey. Data were gathered in the season of 2016-2017 from 136 enterprises which were chosen by the Simple Random Sampling Method. In order to determine the energy efficiency of cotton, data provided by farmers were utilized. The energy input and output in cotton production were calculated as 57134.25 MJ ha(-1) and 63270.54 MJ ha(-1), respectively. Energy inputs consist of; electrical by 20914.02 MJ ha(-1) (36.61%), chemical fertilizer by 15466.06 MJ ha(-1) (27.07%), diesel fuel by 13828.61 (24.20%), irrigation by 4378.50 MJ ha(-1) (7.66%), machinery by 1136.59 MJ ha(-1) (1.99%), chemical by 830.85 MJ ha(-1) (1.45%), seed energy by 311.99 MJ ha(-1) (0.55%), and human labour by 267.62 MJ ha(-1) (0.47%). Energy in cotton production could be classified as 68.94% direct, 31.06% indirect, 8.67% renewable, and 91.33% non-renewable. Energy efficiency, specific energy, energy productivity, and net energy in cotton production were calculated as 1.11, 10.66 MJ kg(-1), 0.09 kg MJ(-1,) and 6136.29 MJ ha(-1).
