Determination Of Energy Input-Output Analysis In Organic Strawberry Production

Abstract

The aim of this research is to compose an energy input-output analysis of organic strawberry production during the production season of 2015 in Nevsehir province of Turkey. Trials and measurements were done in organic strawberry farm in Nevsehir province. The energy input and output in organic strawberry production were calculated as 79793.66 MJ ha(-1) and 19950 MJ ha(-1), respectively. Energy inputs consist of 26.32 % (21000 MJ ha(-1)) organic fertilizers energy, 23.21 % (18520 MJ ha(-1)) plastic energy, 12.67 % (10108.80 MJ ha(-1)) electricity energy, 11.33 % (9043.93 MJ ha(-1)) human labour energy, 10.19 % (8127 MJ ha(-1)) irrigation water energy, 4.51 % (3600 MJ ha(-1)) farmyard manure energy, 4.45 % (3547.53 MT ha(-1)) diesel fuel energy, 2.78 % (2219.40 MT ha(-1)) machinery energy, 2.37 % (1890 MT MA) transportation energy and 2.18 % (1737 MJ ha(-1)) organic chemicals energy. Energy output/input ratio, specific energy, energy productivity and net energy in organic strawberry production were calculated as 0.25, 7.60 MJ kg(-1), 0.13 kg MJ(-1) and -59843.66 MJ ha(-1), respectively. Among the inputs, renewable energy sources composed 71.36% of the total energy input, which was higher than that of the non-renewable resources.
