Wheat (Triticum aestivum L.) is one of the main cereal crop after rice in India. The maximum plant height, tillers per hill, leaf area index, crop growth rate, relative crop growth were noted higher when hand weeding twice at 45 and 65 days after sowing, which was significantly superior than remaining treatments. Yield attributing characters like spikes hill-1, spike length, seeds per spike and test weight were higher under hand weeding twice at 45 and 65 days after transplanting and found to be at par with metribuzin @ @ 175 g a.i. ha-1. The higher grain and straw yield of wheat were recorded with hand weeding twice at 20 and 40 days after sowing which was found significantly higher grain yield (21.38 q ha-1) than other treatments except application of metribuzin @ @ 175 g a.i. ha-1 (18.16 q ha-1). Two hand weeding (20 and 40 DAS) had minimum dry matter accumulation in case of Chenopodium album L. (7.73 and 1.21 g m-2), Leucas aspera (Willd.) Link (1.24 and 0.0.99 g m-2), Digitaria sanguinalis (L.) Scop. (1.55 and 1.50 g m-2), Spilanthes acmella Murr (0.78 and 1.77 g m-2), Vicia hirsute (L.) Gray (0.92 and 1.00 g m-2), Medicago denticulata Willd. (0.78 and 0.71 g m-2) and others (1.40 and 0.59 g m-2) than remaining weeds at 45 and 65 DAS, respectively, and found significant over rest of treatments. Chenopodium album, Leucas aspera, Spilanthus acmella, Vicia hirsute, Digitaria sanguinalis and Medicago denticulata had higher weed control efficiency (WCE) ranging from 50.6 to 96.4% under two hand weeding (20 and 40 DAS) and lowest (9.5%) weed control efficiency was noticed with Digitaria sanguinalis under one hand weeding at 20 DAS.
