Two-year experiment was conducted during the Rabi season at the agriculture research farm of J.V. College, Baraut (Baghpat) Uttar Pradesh to study the effect of integrated weed management and Wheat + Mustard intercropping system on growth and yield. The experiment was laid out in split plot design and replicated three times. The study examined the impact of two factors, main plot (Intercropping) Sole Wheat I1, Sole Mustard I2, Wheat + Mustard (6:1) I3 and Wheat + Mustard (9:1) I4 sub plot (Integrated weed management) weed free W1, two hand weeding 30 & 45 DAS W2, Pendimethalin @ 1 kg ha-1 as PE + Clodinafop 60 g ha-1 as PoE W3, Pendimethalin @ 1 kg ha-1 as PE + Hand weeding 30 DAS W4 and Weedy check T5. The results also revealed that among the different intercropping treatments the Wheat + Mustard (9:1) slightly better control the Phalaris minor and Chenopodium album weeds overall compared to other intercropping treatments at all the stages in both the years. Among the integrated weed management practices, two hand weeding at 30 and 45 DAS (I₂) demonstrated superior performance in controlling the both the weeds (Phalaris minor and Chenopodium album) second only to the weed-free treatment.
