A field experiment was conducted in two locations, the first in the research station of the College of Agriculture, University of Basrah, the Karmat Ali location in a loamy mixture soil, and the second location in the city of Al-Zubair in a sandy loam soil during the season 2021-2022.To study the effect of tillage type and depth on some physical soil properties (soil bulk density, soil penetration resistance) and potato yield (tons.ha-1). The experiment was designed using a one-time split block method in three replicates. The type of plow occupied the main plots with three treatments: control treatment (without tillage NT), Moldboard plows (MP), and backhoe plow (CP). The tillage depth of the split plots was: D1 (0 - 15) cm, D2 (15 - 25) cm, D3 (25 - 35) cm. The results of the study showed a decrease in the bulk density and soil penetration resistance in the tillage treatments compared to the no-tillage treatment. The Moldboard plows treatment was significantly excelled in improving these traits in both locations and at the two measurement periods in the middle and end of the season on the two treatments of chisel plows and the no-tillage treatment.
