The decline in wheat yield is due to several reasons, the most important of which is weed losses. Therefore, a field experiment was conducted in the experimental field of the Department of Field Crops, College of Agricultural Engineering Sciences, University of Baghdad, Al-Jadria during the winter season 2020–2021. The research aimed to study the effect of some herbicides (Crash + U46 combination (1 + 1 L/ha) and Excile (1.5 L/ha). Besides, weed-free and weedy treatment in the companion weeds, yield and its components for three cultivars of wheat (Shame 6, Samur, and Graime). The experiment was laid out in randomized complete block design, arranged according to a split plot with three replicates. The cultivars represented the main plots, and herbicides represented the sub-plots. The results showed the superiority of the combination treatment (Crash + U46) for all characteristics, achieved the better average number of spikes that amounted to 432.2 spikes/m2, the number of grains/spike amounted to 44.66 grains/spike. The weight of 1000 grains amounted to 48.32 g, and the grain yield amounted to 1.8367 t/ha compared to the weedy treatment, which recorded the lowest averages. The cultivar Samur with the combination (Crash + U46) recorded an average grain yield of 1.8933 t/ha. The Samur cultivar exceeded by achieving the lowest average number of companion weeds amounted to 23.25 weeds/m2, recorded the better percentage of weed control that amounted to 62.26%.
