Abstract
A field experiment was conducted in a field of the Faculty of Agriculture /University of Baghdad in 2011 to study the effect of tractor speed with tillage depth in some technical indicators, fuel consumption and total costs of the Locally Modified Sweep plow with tractor Massey Ferguson MF 650 as a machine unit till plow silty clay loam soil. In this study three levels of tillage speeds was used included 2.458, 5.298 and 6.654 km/h and two levels of tillage depth included 10 - 15 and 15-20 cm . Study in this experiment included: slippage percentage, practical productivity, fuel consumption and total cost of the mechanical unit, were measured in this study under randomized complete block design with three replications. The results were as following increasing tractor speed from 2.458 to 5.298 and to 6.654 km/h caused a significant increase in slippage percentage, practical productivity and a decrease fuel consumption and total cost of the mechanical unit. Increasing in tillage depth from 10-15 to 15-20 cm to caused a significant increase in slippage percentage, fuel consumption, total cost of the mechanical unit and a decrease in practical productivity. The interaction between tillage speed 2.458 km/h with depth of plowing 10-15 cm was superior in getting less slippage percentage 4.562%. The interaction between tillage speed 6.654 km/h with depth of plowing 10-15 cm was superior in getting less fuel consumption 21.317L/ha and less total cost 29361.0ID/ha and getting highest practical productivity 0.950 ha/h. We recommend to work at tillage speed 6.654 km/h with depth of plowing 10-15 cm to get highest practical productivity and getting less fuel consumption and total cost of the mechanical unit.
