Effect of Tillage and Weed Management on Grain Yield and Nutrients Removal by Wheat (Triticum aestivum) and Weeds

Tillage practice like rotavator twice recorded significantly lower weed population and weed dry-biomass, increased grain yield, higher NPK uptake by crop and lower depletion of these nutrients by weeds than fanner's practice and zero tillage. Mixture of isoproturon and 2, 4-D and isoproturon alone recorded significantly lower weed population than hand weeding but minimum weed dry-biomass, nutrients removal by weeds, higher grain yield and maximum nutrients uptake by the crop were recorded in hand weeding.
