Abstract

This study was conducted to determine the energy balance between the energy inputs and yield for banana production in Turkey. For this purpose the data were collected from 33 banana orchards. The following results were obtained from this study: the total energy input of 63,009.77 MJ ha-1 was required for banana production. The share of chemical fertilizers was 32.60% in the total energy input. This was followed by farm manure (22.31%) and diesel fuel (15.91%), respectively. The energy efficiency, energy productivity, specific energy, and net energy were found as 1.21, 0.64 kg MJ-1, 1.56 MJ kg-1 and 13,489.21 MJ ha-1, respectively. The results of econometric model estimations revealed that the impact of human labor, machinery, chemical fertilizers, diesel-fuel and water for irrigation energy inputs were significantly positive on yield. The results of sensitivity analysis of the energy inputs showed that the MPP value of water for irrigation was the highest, followed by human labor, machinery energy inputs, respectively. © Erdemir Gundogmus, 2013.
