Investigating the Energy Consumption and Economic Indices For Sweet-Cherry and Sour-Cherry Production in Northeastern Iran

The aim of this study was to investigate the energy consumption and production costs of sweet-cherry and sour-cherry in northeastern iran. required data were collected from 75 sweet-cherry and 42 sour-cherry producers. the total energy inputs in sweet-cherry and sour-cherry production were estimated as 37.76 and 31.03 gjha^-1, respectively. the energy efficiency of sweet-cherry production was greater than sour-cherry production. chemical fertilizers and diesel fuel were the most highly consumed energies in both crops. the higher share of non-renewable energies consumed to produce sweet-cherry than sour-cherry revealed that sweet-cherry production was more dependent on non-renewable sources compared with the sour-cherry production. the economic analysis revealed that production costs for sweet-cherry were higher than sour-cherry but sweet-cherry was more profitable than sour-cherry because of premium prices for sweet-cherry. the modeling results showed that the human labor input had the most impact on costs of both crops. as a consequence, the main practical solutions could be saving in diesel fuel and fertilizer management, which could more properly overcome economic and energy problems in the two crops.
