A field trial was carried out in Sulaymaniyah Governorate during the autumn season of 2021 to study the effect of the number of Repeat herbicides the effect on weed accompanying peach trees yield and fruit quality characteristics. The first factor is the number of applications of herbicides (once, twice) and the second factor is the five control treatments (control, glyphosate 1500 ml/dunam herbicide concentration, glyphosate1000 ml/dunam herbicide concentration + magnetization of the spray solution, paraquat herbicide concentration 500 ml/dunam, and paraquat herbicide concentration 250 ml/dunam+ magnetization of the spray solution). The results indicated that repeat control times gave a significant effect on the wet and dry weight of the weed roots 40 and 60 days after control gave a weight of (161.54, 136.18) gm of wet weight a (66.39, 48.23) mg of dry weight. The treatment of glyphosate + magnetization of the spray solution achieved the lowest wet and dry weight after 23.682 mg 60 days after control, as for the effects of interaction tow applications with the treatment of glyphosate + magnetization of the spray solution, the lowest dry weight was reached 19.493 g after 60 days for control. Paraquat treatment achieved the highest yield/tree rate of 17.917 kg, and one of peach 135.739 g and size of peach 118.33 cm3, the treatment of glyphosate + magnetization of the spray solution achieved the highest control rate of 87.3%, and the lowest control rate was 44.0, which was achieved with Paraquat. Concluded from this
trial that the herbicides affected controlling the weeds associated with peach Increasing yield and quality.
