The experiment was applied in the Field Crops Department at the College of Agriculture, University of Baghdad for the 2023 season. The study aimed to study the effect of soil covers s on the apparent density of the soil during the depth of the sandy soil and the effects on the growth and yield of the white corn according to the factorial experiment according to the decision of the complete random complete block design (RCBD) with three replications. The first factor is covers (wheat straw, white polyethylene, sand, control). The second factor is irrigation methods (irrigation in ponds, irrigation). It also includes measurements of the apparent density of the soil randomly in the depths of the soil where the root mass of the plant is distributed white corn (0-10, 10-20, 20-30, 30-40, 40-50 cm) measurements during the growing season. White corn is planting for the fall season on 20/7/2023 at a depth of 5-10 cm after preparing the land for agriculture. The data of the moisture description curve the irrigation schedule is based on the addition of irrigation water when 50% of the available water is used up and the apparent density measurement before planting and after harvesting.
