| Abstract | ||
| In order to reach the best date for planting the barley crop after spraying the herbicide Trflan with different concentrations, this study was conducted during the agricultural season 2020-2021 at the Agricultural Technical College / Mosul. The experiment was applied on the factorial system of experiments, in RCBD, with three replications. The first factor: the planting date after spraying the herbicide and at three levels (cultivation immediately after spraying, cultivation one week after spraying the herbicide, cultivation two weeks after spraying the herbicide) . The second factor: the concentration of the herbicide at four levels (0, 2200, 2600, 3000) cm3 . ha-1. , (which is the control treatment, less than the recommended concentration, the recommended concentration and higher than the recommended concentration) .The results obtained are summarized as follows: - The cultivation after a week of spraying the herbicide Treflan achieved the best results in all the studied traits. - The use of a low concentration of Treflan (2200 cm3.ha-1) achieved the best results compared to high concentrations. - The interaction between the sowing date was achieved after a week of spraying the herbicide, Treflan, with a concentration of 2200 cm3. ha-1 has the best results and for all studied traits. | ||
