SUMMARY
This study includes the agricultural enterprises producing pear which apply and do not apply good agricultural practices in Thrace Region. The basic purpose of this study is the determination of input use amounts and energy use efficiency and economical comparison of the enterprises applying and not applying good agricultural practices. In Kirklareli, Edirne and Tekirdag, 16 pear producers which carry through good agricultural practices participated in the survey. According to the results, total energy input, energy output, energy output/input ratio, energy productivity, specific energy, energy density and net energy were determined to be respectively as 30.046.64 MJ, 36.000 MJ, 1.20, 0.50 kg/MJ, 2.00 MJ/kg, 1.80 MJ/TL and 5.953.36 MJ in the enterprises applying good agricultural practices. Total energy input, energy output, energy output/input ratio, energy productivity, specific energy, energy density and net energy were determined to be respectively as 32.111.92 MJ, 33.600 MJ, 1.05, 0.44 kg/MJ, 2.29 MJ/kg, 2.05 MJ/TL and 1.488.08 MJ in the enterprises not applying good agricultural practices. In Thrace Region the cost of producing; one kg of pear was calculated 1.11 TL in the enterprises which applied good agriculture while it was calculated 1.12 TL at the enterprises which did not apply the good agriculture. Total expenses, gross output value, gross profit, net profit and relative profit were determined to be respectively as 16.682.80 TL, 24.250 TL, 14.938.10 TL, 7.567.20 TL and 1.45 in the enterprises applying good agricultural practices. Total expenses, gross output value, gross profit, net profit and relative profit were determined to be respectively as 15.652 TL, 21.000 TL, 11.511.80 TL, 5.348 TL and 1.34 in the enterprises not applying good agricultural practices. According to energy use efficiency and economic analysis results, pear farming was determined to be more advantageous in the enterprises applying good agricultural practices.
