Abstract

Abstract The experiment was conducted at the research station of the Field Crops Department of the College of Agriculture, Tikrit University, during the winter season 2022-2023, with the aim of knowing the effect of the concentrations of some herbicides, as well as the competitive ability of some bread wheat varieties. A completely randomized block design (split-factorial) was used. The experiment includes two factors. The first factor (herbicides) in (main plot): Selective weed herbicides to combat the weeds accompanying the wheat crop. In addition to the first indoor treatment (Atlantis) to combat narrow and broad-leaved weeds, with three concentrations (480, 320, 160) g/ha + (480) milliliters of diffuser for every 400 liters/ha. Secondly (Topic) to combat the narrow-leaved weeds at a concentration of (600, 300, 900) liters/ha, ml per 400 liters/ha. In addition to the comparison treatment untreated (control), where it was sprayed with distilled water only. The second factor is the variety factor : three varieties of soft wheat crop, namely (Badriya, Gad and Bentlou). The results of the experiment showed the following regarding the rates of the varieties outperforming the Jad variety, with a percentage of control reaching (50.04)%. The Bentlow variety was superior in terms of total yield, inhibition rate, and lowest weed weight At a rate of (320) kg/ha, (48.45)%, and (230.6) plants/m2, respectively. While the Badriya variety excelled in terms of having the highest seed weight, which reached (41.77) grams. As for herbicide rates and concentrations, the herbicide Atlantis at the recommended concentration recorded the highest values for the weight of the weed, the percentage of weed inhibition, the percentage of weed control, the weight of 1000 grain, and the total yield At a rate of (166.3) plants/m2, (59.94)%, (57.14)%, (40.59) grams and (3.75) tons/ha-1, respectively.
