Energy Input-Output Analysis in Organic Mulberry (Morus spp.) Production in Turkey: a Case Study Adiyaman-Tut Region

Abstract

The goal of this study is to do the energy input-output analysis of organic mulberry. This study was conducted at the organic mulberry producing facilities during the 2015-2016 production seasons in Adiyaman-Tut region of Turkey. The agricultural input energies and output energies used in organic mulberry production were computed to determine the energy input-output analysis. According to the research findings, the energy inputs in organic mulberry production were computed respectively as 3948 MJ ha(-1) (59.01%) drip and sprinkler irrigation energy, 1092.42 MJ ha(-1) (16.33%) gravity irrigation energy, 449.33 MJ ha(-1) (6.72%) diesel fuel energy, 416.52 MJ ha(-1) (6.23%) farmyard manure energy, 335.14 MJ ha(-1) (5.01%) human labour energy, 253.52 MJ ha(-1) (3.79%) machinery energy, 93.12 MJ ha(-1) (1.39%) transportation energy, 75.78 MJ ha(-1) (1.13%) animal labour energy and 26.62 MJ ha(-1) (0.40%) organic fertilizer energy. Total input energy was computed as 6690.46 MJ ha(-1). Production output organic mulberry yield were calculated as 37,627.84 MJ ha(-1). The energy output/input ratio, specific energy, energy productivity and net energy computations were computed respectively as 5.62, 1.51 MJ kg(-1), 0.66 kg MJ(-1) and 30,937.37 MJ ha(-1). The consumed total energy input in organic mulberry production could be classified as 88.20% direct, 11.80% indirect, 88.10% renewable and 11.90% non-renewable.
