| Abstract | ||
| The research was carried out in the Agricultural Technical College / Mosul during the agricultural season (2021-2022) in plastic anvils with a height of 30 cm and a diameter of 30 cm, and according to the system of global experiments and with a complete random design and with two factors, the first factor is the stages of spraying the herbicide and at three levels (early growth stage, tillers stage, batting stage) , The second factor was concentrations of the herbicide at four levels (zero, 200, 300, 400) g/ha and three replications. The results showed that the early spraying of the herbicide had a significant effect on most of the studied traits, and that the increase in the concentration of the herbicide affected the weed plants and decreased the number of their weeds and significantly, and that the low concentration significantly outperformed the number of wheat plants and in the area of the flag leaf. And that the interaction between all the spraying stages of the herbicide and the high concentration caused the killing of all the weed plants, and it reduced the number of the weed tillers until it reached (1.33) tiller when the interaction between the spraying of the herbicide in the lining stage and the high concentration. The interaction between spraying the herbicide in the early growth stage and the low concentration of the herbicide achieved a significant superiority in the number of tillers of wheat crop plants and the area of the flag leaf | ||
