Heavy weed infestation has become a significant concern in boosting and maintaining wheat productivity. Weeds reduce wheat yield by 25-40%. Effective weed control is essential for increasing wheat productivity, necessitating a detailed analysis of weed flora. Thus, weed management through a proper combination of herbicides can be an option to effectively manage complex weed flora without crop injury. Therefore, a field study was conducted at Agricultural Research Farm, AICRP on Wheat, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, during the Rabi season of 2021. The experiment comprised five post-emergence herbicides application (pinoxaden at 40 g a.i./ha, pinoxaden at 45 g a.i./ha, pinoxaden at 90 g a.i./ha, clodinafop propargyl at 90 g a.i./ha, sulfosulfuron at 25 g a.i./ha) along with weed-free and weedy check treatments. The crop was infested with Phalaris minor, Cichorium intybus, Medicago denticulata and Avenaludoviciana. The results showed that weed management practices significantly influenced grassy, broad-leaved weeds, weed density and dry weight, and pinoxaden at 90 g a.i./ha effectively controls all types of weeds. However, Growth parameters and yield attributes (plant height, number of tillers/m2, grains/earhead) and grain yield were recorded highest with the post-emergence application of pinoxaden at 45 g a.i./ha and found most remunerative than other treatments.
