A field experiment was conducted in the experimental farm of Department of Agriculture, Himgiri Zee University, Dehradun, Uttarakhand, India during winter season (Rabi) 2018-19. The experiment was conducted in randomized block design (RBD) with 7 treatments, viz. pre-emergence application (PE) of pendimethalin 750 g/ha, pendimethalin 750 g/ha PE followed by (fb) one hand weeding (HW) at 30 days after seeding (DAS), post-emergence application of (PoE) clodinafop 60 g/ha, clodinafop 60 g/ha (PoE) fb one hand weeding (HW) 60 days after seeding (DAS), hand weeding twice at 30 and 60 DAS, weed free and weedy check. All the weed control treatments significantly reduced the weed density and biomass. Hand weeding twice at 30 and 60 DAS recorded highest weedcontrol efficiency and minimum weed index. The integrated weed management treatment including pendimethalin 750 g/ha PE fb 1 HW was superior than other treatments in recording highest plant height, plant population, dry matter, seed/siliqua, siliqua/plant, length of siliqua, seed weight, seed, stover and biological yield of Indian mustard.
