Özet
Greenhouse cultivation is one of the most important income generating branches of agricul-ture. The aim of this study is to do an analyze on energy efficiency of greenhouse tomato produc-tion in the season of 2018 in Siirt province and its sub-districts of Turkey. The energy input and output in greenhouse tomato production has been calculated as 104915.10 MJ ha-1 and 128000 MJ ha-1, respectively. Energy inputs consist of 33.39% (35030 MJ ha-1) chemical fertilizer energy, 19.24% (20184.08 MJ ha-1) human labor energy, 12.81% (13440 MJ ha-1) irrigation energy, 10.20% (10698.90 MJ ha-1) diesel fuel energy, 7.63% (80002.80 MJ ha-1) machinery energy, 6.75% (7084 MJ ha-1) chemi-cals energy, 1.41% (1475.20 MJ ha-1) transpor-tation energy and 0.01% (0.10 MJ ha-1) seed energy. Energy efficiency, specific energy, ener-gy productivity and net energy in greenhouse tomato production has been computed as 1.22, 0.66 MJ kg-1, 1.53 kg MJ-1 and 23084.92 MJ ha-1, respectively.
