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.
