A field experiment was conducted at experimental farm of Dolphin (PG) Institute of Biomedical and natural sciences, Dehradun during 2021. To study the effect of paddy straw mulch and herbicides on weed and crop yield of wheat. The treatments were weedy check, hand weeding/weed free, pre-emergence application of Pendimethalin and Isoproturon, post emergence application of Clodinafop propargyl, metsulfuron methyl, pinoxoden, 2, 4-D and paddy straw mulch. Cynodon dactylon, Chenopodium album, Fumaria parviflora and Polygonum aviculare were the dominant species. The studies envisaged that the wheat crop covered with paddy straw mulch showed better results in terms of weed density at different days, weed control (WCE, WI and Dry weight of weed) and crop growth parameters (spikelet’s/tillers, grain yield and straw yield) as compared to the pre-emergence herbicide and post emergence herbicide.
