Abstract
One of the basic tasks in agricultural mechanization technology is to reduce energy consumption in agricultural operations, especially in tillage . Experiment was conducted in fields of Al- Bdaa in Iraq season 2024 . this research studied, Soil Disturbed Volum , Practical productivity, and Tractive efficiency. best Indicator involved three levels of tractor speeds (2.70, 3.40 ,3.78 km . hr-1) and three levels of tilt depths (18 , 22 , 27)cm. Factorial Experiments under (RCPD ) with three replications was used in this study . It was verified superiority tractor velocity 3.78 km.h-1 gets highest value soil disturbed volume which amounted 100.9m3.hr-1and higher Practical productivity 0.813 ha.hr -1 , while velocity 2 .70km.hr-1 gets less tractive efficiency 63.23 %, tillage depth 18 cm gets lowest percentage of tractive efficiency 62.11% ,depth tilled 27 cm by using moldboard plow gets highest value in soil disturbed volume 98.19m3.hr-1and practical productivity 0.843 ha.hr-1. interaction between tractor speed 3.78km.hr-1 with tillage depth 27 cm was superior in getting the highest(S. D. V)100.9m3.hr-1 . practical productivity 0.907 ha.hr-1 and higher tractive efficiency 72.00 %.
