In this experimental study, the conventional tillage, reduced tillage and direct sowing were applied for rapeseed cultivation. The main objective of the present study was to evaluate the effects of different tillage systems on the crop yield and fuel consumption for winter rapeseed cultivation. The values of specific fuel consumption and seed production were calculated for winter rapeseed production. It was found that the seed yield for the conventional tillage, reduced tillage and direct sowing were determined as 2144.4 kg/ha, 1956.5 kg/ha and 1724.4 kg/ha, respectively. It was determined at the end of evaluation that tillage systems statistically (P<0.01) affected the yield. It was found that the seed yield for the conventional tillage, reduced tillage and direct sowing were determined as 2144.4 kg/ha, 1956.5 kg/ha and 1724.4 kg/ha, respectively. When compared to conventional tillage, while the seed yield reduced in 8.76% and 19.58%, the fuel consumption reduced in 40.3% and 63.2% in reduced tillage and direct sowing applications, respectively, The specific fuel consumption in winter rapeseed cultivation was 33.93 L/t, 22.20 L/t and 15.51 L/t, for the conventional tillage, reduced tillage and direct sowing applications, respectively. The specific seed production in winter rapeseed cultivation was 29.47 kg/L, 45.03 kg/L and 64.43 kg/L for the conventional tillage, reduced tillage and direct sowing applications, respectively.
