During the agricultural year 2020–2021, an experiment was carried out in clay soil at the College of Agriculture / University of Basrah to investigate the impact of the elements under investigation on the mean weight diameter (MWD) in clay soil. The factors under investigation were as follows: the solid sprinkler irrigation system's operating pressure, which was set at 150 kPa (P1), 250 kPa (P2), and 350 kPa (P3); the moisture depletion, which was set at 75 % (M1) and 50 % (M2) of the available water; and the soil pulverization, which was set at two different levels: high pulverization (C), which was done once after plowing, and low pulverization (S), which was done three times after plowing. The findings indicated that the mean weighted diameter increased as the P1 to P2 and P3 outcomes increased. increase mean weighted diameter in treatment M1 comparison with treatment M2, high pulverization on (C) appeared high MWD comparison with (S) treatment in the middle and late growing season, barley crops are harvested respectively.
