The research was conducted during 2022-2023 at the Rashedia Research Station in order to evaluate performance of the dinitroaniline herbicide when the Glycine max L. crop planting dates differed. The research encompassed two factors, the use of dinitroaniline herbicide is discussed at two levels, second: Planting date of the crop after spraying the herbicide is determined at three levels: immediate, a week, and two weeks post-spray. Research was applied using the method of the study utilized global experiments and a randomized complete block design (RCBD) with three replications. The data was collected and analyzed using the SAS program at the end of the season. The Duncan multiple range test was used to distinguish different averages with different alphabet letters in research. The results showed: that treatment dinitroaniline herbicide is being used achieved a decrease significant increase in the dry weight of the weed and percentage of germination, and a significant increase in plant height, number of pods, and weight of 100 seeds. Planting two weeks after spraying the herbicide significantly reduced the weed's dry weight, and a significant increase in both plant height, the number of pods, and the weight of 100 seeds. Interaction between the control treatment and planting two weeks after spraying the herbicide resulted in a significant increase the dry weight of the weed. is measured (g). Interaction between herbicide treatment and planting immediately after spraying resulted in a significant decrease in the percentage of germination. The herbicide treatment and planting interaction led to significant increases in plant height, pod number, and seed weight two weeks post-spray.
