Abstract
I
n this research, the energy flow and production energy
indices of canola cultivation in Trakya province of Turkey,
Golestan and Mazandaran provinces of Iran were compared.
Diesel fuel and chemical fertilizer inputs were the highest consumer
of energy in the production of canola in these three
regions. The results indicated that despite the higher energy
use of machinery in Trakya province of Turkey, the energy use
of diesel fuel in this province is less than the energy consumed
in the two northern provinces of Iran, which could be due to
available old machines for the production of canola in
Mazandaran and Golestan provinces. Total greenhouse gas
emissions of canola production for these regions were computed
562.85, 652.86 and 887.30 kgCO
2eq ha-1, respectively. The
inputs of chemical fertilizer and diesel fuel in canola production
produced the highest percentage of gas emissions in these
three areas. Energy consumption for potential feedstock production
for one kg production of biodiesel fuel in these
provinces was calculated as 14.76, 20.66 and 37.77 MJ, respectively.
The amounts of greenhouse gas emissions for
potential feedstock production for one kg production of biodiesel
were obtained 0.45, 0.76 and 1.17 kgCO
2eq for Trakya, Golestan
and Mazandaran provinces, respectively.
