摘要

A study was performed with the two essential types of plows most frequently used in Iraq, with four forward speeds.rnThe main aim of the study was to observe the effect of plow types and operational speed on field capacity and bulk density. The best type of plow and speed were identified along with interactions. The study used a split-plot, completely randomized block design in three replications.rnThe results showed that influence of speed was significant with field capacity and bulk density but the influence of type of plow had no significant influence on the field capacity or bulk density. The interaction between the type of plow and speed had no significant influence on the field capacity and bulk density. The highest field capacity was 0.592 ha/ h at the fourth speed with the disc plow. The lowest bulk density was 1.21 g/cm~3 at the first speed with thernmoldboard plow.
