Abstract
The current study observes the input/output energy quantities and its associated financial value, in vegetable greenhouses on Crete, Greece, for the 2015-2016 cropping seasons. The utilized data was taken in regular direct basis for the implementation of energy input-output analysis and data envelopment analysis. For input data analysis, four crop practices were used tomato, pepper, cucumber, and eggplant. The outcomes of the expended majority of energy input-output analysis showed that fertilizers count for 53%, fossil fuel counts for 16%, and electricity counts for 12%. The mean crop and energy consumption for each crop practice were estimated as 94,036MJ/ha and 171,950kg/ha, 115,473MJ/ha and 173,000kg/ha, 81,196MJ/ha and 128,893kg/ha, and 146,067MJ/ha and 209,501kg/ha, respectively. Inputs with the biggest shares in total inputs were manpower counts for 30%, fertilizers count for 22%, and crop protection counts for 16%. DEA method showed that the mean values of technical efficiency, pure technical efficiency, and scale efficiency were 0.90193, 0.97272, and 0.80322, respectively. The mean scale efficiencies were set as 0.80. The findings of this research would be valuable to the inefficient producers undertaking into consideration the recommendations made by this method, where the overall input in Euro could be meaningfully condensed without any reduction on the current overall output.
