An experiment was conducted in fields of Agriculture college, University of Basrah.
The experiment was designed with split-spilt plots in Complete Randomized Blocks Design Treatments included three types of moldboard plows: helical, semi digger and general –purpose, three soil moisture content levels (10.23,16.47 and 24.68%), and four tractor speed of 0.41, 0.56, 0.86 and 1.21 m sec -1 .
The soil physical properties were determined after plowing soil by using three types of moldboard plow.
The results showed that there was significant effect of moldboard plow types, soil moisture content and tractor speed on soil physical properties including bulk density, soil porosity, soil penetration resistance and pulverization ratio.
Results also indicated that the effect of interaction among plow types, soil moisture content and tractor speed was significantly on soil penetration resistance and pulverization ratios while it had not significantly effect on bulk density, soil porosity.
In general, soil physical properties, had been improved when using high tractor speed and moderate soil moisture content whereas optimal operation was obtained when using general-purpose plow type and high tractor speed of 1.12 m sec -1 and soil moisture content of 16.47% where this combination gives low bulk density (0.96Mg m-3), high soil porosity (63.90%) high soil pulverization ratio (74%) and low soil penetration resistance (623.47 kN m-2).
