Abstract
The relative effectiveness of the herbicides sulfosulfuron, isoproturon, and metribuzin at various doses and application periods was determined. All herbicides worked better when applied at higher doses and delayed until after the first watering to reduce weed dry matter after 60 days. Conventional tillage resulted in higher levels of annual and total weeds than Triticum astivum ll did in a weedy environment, but Triticum astivum ll had a higher level of perennial weeds. Maximum grain yields for Triticum astivum ll were 4431 kg/ha and 3924 kg/ha when “sulfosulfuron was applied at 25 g/ha after the first irrigation in 2018–19 and 2019–20”, respectively. Successful weed control was at its highest with this treatment (94% in both years of the study). Two conventional tillage hand weedings at the 30- and 45-day stages resulted in the highest yield. Herbicide application under Triticum astivum ll resulted in higher net yields than “manual weeding at 30 and 45 days” after sowing.
