ENERGY CONSUMPTION AND COST ANALYSIS FOR POTATO AND ONION WITH CONVENTIONAL AND GOOD AGRICULTURAL PRACTICES IN MIDDLE BLACK SEA REGION OF TURKEY

摘要

This study covers the agricultural farms producing potato and onion which apply good agricultural practices and apply conventional agricultural in Middle Black Sea Transitional Zone of Turkey.The basic purpose of this study is the determination of input use amounts and energy use efficiency and economical comparison in the farms that make the conventional and good agricultural practices.In study region the survey were made with 40 farms producing potato and onion.According to the research results,the energy value of the total inputs for potato production in the farms that make good agriculture practice is 33802,69 MJha"1 and for in the farms that make conventional agricultural it is 37192,92 MJha-1.The energy value of the total inputs for onion production in the farms that make good agriculture practice is 25478,07 MJha1 and for in the farms that make conventional agricultural it is 29707,81 MJha1.The energy use efficiency and energy productivity of the potato and onion produced by applying good agriculture in the research region was higher than that of traditional agriculture.The cost of potato producing; one kg of potato was calculated 0,23 $ in the farms that make good agriculture practice while it was calculated 0,15 $ at the farms that conventional agriculture.The cost of onion producing; one kg of onion was calculated 0,25 $ in the farms that make good agriculture practice while it was calculated 0,17 $ at the farms that conventional agriculture.As a result,it is more advantageous to use good agricultural practice method in terms of energy efficiency.Conventional agricultural is more advantageous in terms of production cost.
