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