Abstract:
An investigation was carried out at Agronomy farm, Sai Institute of Paramedical and Allied Science, Dehradun during rabi 2021-22 to find out the “Effect of weed management practices on weeds and productivity of wheat (Triticum aestivum L.)”. Twelve practices of weed management were used for research with three replications in randomized block design. PBW-154 variety of wheat was used as test crop. Among herbicides, post-emergences application of Clodinafop + Metsulfuron (60+4) @ 64 g a.i. ha^-1 reduced better dry matter of weed, which was statistically at par with over rest of the treatments, except weed free, two hand weeding at 20 and 40 DAS and Sulfosulfuron + Metsulfuron @ 30+2 g ha^-1 and also increasing growth parameters i.e., plant height, fry matter accumulation, number of tillers m^-2 and leaf area index, grain (51.20 q ha^-1) and straw (64.10 q ha^-1) yield of wheat. Herbicides applied as post-emergence and hand weeding at 20 and 40 DAS can all help the crop's weed-suppressing abilities.
