الملخص EN

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.

ha¹., (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.ha¹) 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' has the best results and for all studied traits.
