This research examined the energy use pattern and energy
input/output analysis of pistachio nut widely grown in the
South-eastern Anatolia, Turkey. For this purpose, data from
pistachio nut production were collected in 61 farms from ten
villages by a questionnaire which was selected according to
their regional properties. As a result, the total energy
input used in various farm operations for cultivating the
pistachio nut fruit was calculated to be 4286.8 MJ ha-1.
Out of all operations, tillage consumed maximum energy. This
operation was followed by spraying, and then by harvesting,
transportation, and fertilizer application. The total energy
requirement consumed in various energy sources for the
pistachio nut fruit was calculated as 12044.0 MJ ha-1.
The average fruit yield of the pistachio nut was determined
as 1500 kg ha-1 and its output energy was
calculated as 17 700 MJ ha-1.
