| Abstract | ||
| The experiment in a field trials of the Faculty of Agriculture / University of Baghdad, which lies 20 km west of Baghdad in 2011 to study the effect deep tillage and and velocity the tractor in some technical indicators and economic disc plow, were used in the experiment tractor type MF and disc plow, which represented two-speed are 3.42 and 8 km / main levels hour and represented depth 15 and 25 cm secondary levels in the experiment. The study attributes the following percentage of slip, fuel consumption l / ha, production process hectares / h, the volume of soil raised m3 / h, the total cost of the tractor and plow JD / ha. In this study, the design used panels dissident Design Split-Plot sectors randomized complete system Randomized Complete Block Design and three replicates and tested the differences in a less significant difference (LSD) at the 0.05 level of probability and the results were as follows: - 1 - led increase the speed of the tractor from 3.42 to 8 km / h to a significant increase in the percentage of sliding from 9.80 to 13.60% and productivity process from 0.23 to 0.56 hectares / hour and soil volume raised from 392.50 to 977.50 m ³ / h and a reduction in costs total of 98838.6 46651.2 JD / ha and fuel consumption of 36.10 to 30.40 l / ha. 2 - led increasing depth from 15 to 25 cm to moral influence in increasing the percentage of sliding% from 9.60 to 13.80% and the fuel consumption of 31.30 to 35.20 liters / ha and soil volume raised from 600 to 770 m ³ / hour and the total costs of 70820.4 74669.3 JD / hectare to decline in the production process from 0.40 to 0.39 hectares / hour. 3 - raised overlapping bilateral speed jars 3.42 km / h and the depth of the plow 15 cm morally in the percentage of sliding reached the lowest value 8.40% and the fuel consumption to get less value amounted to 28.60 l / ha between the speed of the tractor 8 km / h and the depth plow 15 cm and in the production process between the speed of the tractor 8 km / h and 15 cm depth of the plow a significant impact in getting the highest value reached 0.57 hectares / hour. | ||
