Özet

This research examines the energy use patterns and energy input-output analysis of apple production in the Antalya province, which is an important agricultural center in Turkey. Data for the apple production were collected from 90 apple farms by using a face-to-face survey method. The energy input of chemical fertilizer (41.03%), mainly nitrogen, has the biggest share in the total energy inputs followed by electricity (29.21%). The apple production consumed a total of 43,404.31 MJ ha(-1). The energy ratio for apple was estimated to be 1.51. The specific energy, energy productivity, energy intensiveness and net energy yield were 1.59 MJ kg(-1), 0.63 kg MJ(-1), 3.31 MJ TL-1, and 22,103.83 MJ ha(-1), respectively. The non-renewable form of energy input was 95.76% of the total energy input used in apple production compared to only 4.01% for the renewable form. The benefit-cost ratio of the cotton production was 1.48.
