Abstract
An experiment was undertaken in a field of the Faculty of Agriculture at Abu-Ghraib on a silty clay loam soil in April 2009. This was to study some technical parameters and energy requirements for a machinery unit. Three levels of tillage depth included 10, 20 and 30 cm representing main plots and tractor speed included 3.21 and 3.72 km/h representing sub plots were used. Slippage percentage , practical productivity, soil disturbed volume and fuel consumption were studied in this experiment .A split plot arrangement with completely randomized design with three replications was used .The results showed that increasing speed from 3.21-3.27km/h lead to increased slippage percentage , practical productivity and soil disturbed volume but decreased fuel consumption . Increasing the depth represents 10-20-30 cm lead to increased slippage percentage and fuel consumption but decreased practical productivity and soil disturbed volume. The first depth (10 cm) with second speed (3.27 km/h) gave the highest rate of practical productivity (0.2667 ha/h). The third depth (30 cm) with second speed (3.72 km/h) gave higher rate of soil disturbed volume (637.7 m3/h). While the third depth (30 cm) with second speed (3.72 km/h) gave the less rate of fuel consumption per unit area (72.5 l/h). We recommend the use of second speed (3.27km/h) and depth (30cm) because it scored the third highest rate of the volume of soil and raised the lowest rate of fuel consumption per unit area.
