| Abstract | ||
| A field experiment was conducted in the Kurdistan Region of Iraq for the agricultural season 2022-2023 in the fields of the Agricultural Research Station in Erbil - Ain Kawa Governorate, Lat. 36014'51.0"N, long. 43059'50.5"E). In order to the effect of herbicides (Imazethapyr and a mixture of Bentazone + Gallant Super) and their recommended dose for each of these herbicides and the spraying at four periods (two, four, six and eight weeks) after germination for the soybean crop, (Shaimaa cultivar). On 28/5/2022, the experiment was applied according to the complete randomized block design (R.C.B.D.) as a factorial experiment with three replications, and statistical analysis of the data revealed and the following main results: There were significant differences among the average treatments in the effects of herbicides in all characteristics of the yield, except for the weight of 100 seeds.Weed free treatment was superior, followed by the Imazethapyr in terms of number of pods per plant, number of seeds perpods, seeds yield , biological yield, harvest index for which the weed-free treatment . There were significant differences among the averages of the treatments in the interaction between the factors of the study for all growth characteristic. The results also showed that there were significant differences in the percentage of oil and protein | ||
