| Abstract | ||||
| A study was conducted at the field of College of Agriculture, Abu-Ghraib to explore the effect of different tillage depths and soil moisture contents on the weed control. Split plots design with complete randomized was used. The involved factors comprise the soil moisture content (main plots) with three levels (14, 17, and 19%), three different depths (sub plots) (10, 15, and 20 cm). Results indicated that the lowest penetration soil resistance was obtained at 10 cm tillage depth and 17% of soil moisture content. On the other hand, the lowest attractive force was achieved at 10 cm depth and 17% of soil moisture. Lowest value of controlled weed population was realized at 15 cm tillage depth and 17% of soil moisture content where as the maximum weed control percentage was obtained at 10 cm tillage depth and 19% of soil moisture content. | ||||
