Optimization of vertical disc plow performance under dry farming condition

Abstract EN

The study was conducted in the field of Agriculture Faculty, University of Duhok by using different speeds of tillage: (4.21 , 5.25 and 7) km/h with three angles (35°, 45°, 55°) of the vertical disc plow, the effect of speeds and angles in bulk density, porosity, actual depth, slipping percentage, fuel consumption, field efficiency, and productivity.

The results indicated that the interaction between the factors had a significant effect in some of the studied properties, the speed (4.21 km/h) and angle 35° was better than other treatments, which was 6.17 % in slipping, while the speed (5.25 km/h) and angle 55° exceeded the other treatments in the actual depth, actual width, fuel consumption and field efficiency which was 14.40 cm, 2.81 m, 8.33 L/ ha, 72.07 %, respectively.
