Özet:
The aim of this research is to compose an energy input-output of guar and lupin production during the production season of 2015 in Bingol province of Turkey. The energy input in guar and lupin production have been computed as 14 619.97 MJ ha(-1) and 23 486.73 MJ ha(-1), respectively. The energy output in guar and lupin production have been calculated as 43 767.21 MJ ha(-1) and 16 554.41 MJ ha(-1), respectively. Energy usage efficiency, specific energy, energy productivity and net energy in guar production have been calculated as 2.99, 6.42 MJ kg(-1), 0.16 kg MJ(-1) and 29 147.24 MJ ha(-1), respectively. Energy usage efficiency, specific energy, energy productivity and net energy in lupin production have been calculated as 0.70, 31.95 MJ kg(-1), 0.04 kg MJ(-1) and -6932.32 MJ ha(-1), respectively. The total energy input used up in guar production could be classified as 51.31 % direct, 48.69 % indirect, 22.24 % renewable and 77.76 % non-renewable. The total energy input used up in lupin production could be classified as 31.35 % direct, 68.65 % indirect, 33.68 % renewable and 66.32 % non-renewable.
