Technique increasing depths of tillage in some characteristics by using moldboard plow

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 %.
