Maize is a major plant in Afghanistan and its seed is worldwide cultivated for various purposes. It is cultivation is on the increase, but in Afghanistan due to the lack of an effective use of corn, and continuous drought, its cultivation has been reduced. Weeds are a part of pests which impose damage to crops yearly and the losses were up to 30 % in some cases, but in some cases it made up to 90 % of the agricultural products. The aim ofthis research is to recognize the different control practices of weeds in maize plant and its effect on grain yield. The research was carried out in 64m2 area of agricultural research farm of Faculty of Agriculture at Kabul University in 2017. The experiment design was CRD with 4 replications that included Herbicide (H) 2, 4-D, plastic mulch (M), hand weed control hoe (HW) and control (C). The amount of urea fertilizer was applied as 250 kg ha-1 in two phases that the amount of first step was 125 kg ha-1 during at 4 leaf stage and during at 12 leaf stage it was applied as amount of 125 kg ha-1. The M treatment weeds were controlled by hand, weeds of HW treatment was controlled by hoe and H treatment weeds was controlled by 2, 4-D herbicide during at 5-8 leaf stage of corn to control broadleaf weeds. The parameters measured include plant height, number of ear and number of grains. The result of M treatment yield was higher among all treatments then HW, H and C treatments yield were recorded. In conclusion, we recognized that the use of different ways of weed control like mulch and herbicide (2, 4-D) have positive effects on corn grain yield.
