Wheat crop is primarily grown in temperate regions and also at higher altitude under tropical climatic areas in winter season. It is the single most important cereal crop that has been considered as integral component of the food security system of the several nations. The productivity wheat in eastern Uttar Pradesh is very low which might be due to the adoption of cereal- cereal (Rice-Wheat) cropping system, Irrigation, poor weed management, poor soil health and imbalance fertilizer used. A field experiment was conducted during rabi season 2015-16 at the Agronomy Research Farm, Narendra Deva University of Agriculture and Technology, Ayodhya comprising 10 treatment, i.e. Pendimethalin @ 0.75 kg a.i. ha-1, Sulfosulfuron @0.025 kgkg a.i. ha-1, Metribuzin @0.21 kg a.i. ha-1, Clodinafop @0.06 kg a.i. ha-1, Pendimethalin + metribuzin @1.0+0.175 kg a.i. ha-1, Pendimethalin fb sulfosulfuron @1.0+0.018 kg a.i. ha-1, Sulfosulfuron+metsulfuron @0.03+0.002 kg a.i. ha-1, Clodinafop+ metsulfuron(Premix) @0.06+0.004 kg a.i. ha-1, Weed free and Un-weeded control with three replications in RBD design. The experimental site was predominantly infested with different weed species belonging to different families such as grasses, broadleaved weeds and sedges. The application of pendimethalin (PE) fb metribuzin (PoE) @ 1.0+0.175 kg a.i. ha-1recorded minimum density and dry weight of weed followed by post emergence application of pendimethalin fb sulfosulfuron @ 1.0+0.018 kg a.i. ha-1. Control treatment has high weed growth throughout the crop growing period leads for the reduction yield. Based on the results, it can be concluded that application pendimethalin (PE) fb metribuzin (PoE) @ 1.0+0.175 kg a.i. ha-1 enhanced the weed control efficiency and also an effective weed management practice with respect to yield and cost of cultivation.
