Aim: To study on Integrated Weed Management of mustard crop (Brassica juncea L.) under mid-hill region of Himachal Pradesh.

Study Design: The field experiment was conducted in randomized block design (RBD).

Place and Duration of Study: A field experiment was carried out during 2022-2023 with the concept of integrated weed management at Abhilashi University Chail chowk Mandi (H.P.).

Methodology: Eight treatments were evaluated in randomized block design with three replications. T₁-Oxadiargyl 0.90 kg a.i. ha^-1 (pre-emergence), T₂^-Oxadiargyl 0.90 kg ai. ha^-1 (pre-emergence) + two hand weeding at 30 and 60 DAS,T₃-Pendimethalin 1.5 kg a.i. ha^-1 (pre - emergence)T₄^-Pendimethalin 0.75 kg a.i. ha^-1 (pre - emergence) + one hand weeding at 30 DAS,T₅-Oxadiargyl 0.90 kg a.i. ha^-1 (pre - emergence) fb IPU 0.75 kg a.i ha^-1  (post emergence),T_6-Pendimethalin 0.75 kg a.i ha^-1 (pre-emergence) fb IPU 0.75 kg a.i ha^-1  (post- emergence),T₇-Two hand weeding at 30 and 60 DAS, T_8-Weedy check.

Results: The investigation found that the most effective ways to control weeds are by keeping the area completely T₂^-Oxadiargyl 0.90 kg ha^-1 (pre-emergence) + two hand weeding at 30 and 60 DAS, which involved keeping the area weed-free, was found to be the most successful in terms of achieving the lowest weed density and highest weed control efficiency.

Conclusion: Based on the results, it can be concluded that integrated weed management practices T₂^-Oxadiargyl 0.90 kg ha^-1 (pre-emergence) + two hand weeding at 30 and 60 DAS, treatment is the most effective option for managing weeds in mustard crop.
