Determination of energy balance of common vetch (Vicia sativa L.), hungarian vetch (Vicia pannonica C.) and narbonne vetch (Vicia narbonensis L.) production in Turkey

Abstract

The aim of this study is to determine an energy balance of common vetch, hungarian vetch and narbonne vetch production during the production season of 2015 in Bingol province of Turkey. The energy input in common vetch, hungarian vetch and narbonne vetch production have been calculated as 13060.72 MJ ha-1, 15767.22 MJ ha-1and 14769.73 MJ ha-1, respectively. The energy output in common vetch, hungarian vetch and narbonne vetch production have been calculated as 42048.22 MJ ha-1, 10051.33 MJ ha-1 and 11963.62 MJ ha-1, respectively. Energy usage efficiency, specific energy, energy productivity and net energy values related to common vetch, Hungarian vetch and Narbonne vetch production have been determined as 3.22, 0.64, 0.81; 5.46 MJ kg-1, 29.98 MJ kg-1, 21.98 MJ kg-1; 0.18 kg MJ-1, 0.03 kg MJ-1, 0.05 kg MJ-1 and 28987.50 MJ ha-1, -5715.89 MJ ha-1, -2806.11 MJ ha-1 respectively for each type. The total renewable energy input applied in common vetch, hungarian and narbonne vetch was 26.85, 20.42 and 29.69 per cent, respectively.
