Field experiments were carried out at Horticulture Farm, Department of Horticulture, SKN Agriculture University, Jobner during 2016-17 and 2017-18 rabi seasons in the loamysand soil to study the effect of weed management and plant nutrition practices on weed infestation and NPK depletion by weeds in onion (Allium cepa L.). Weed management practices included seven weed control treatments. The crop was fertilized with four levels of N under the recommended rate of P, K, and S. The results indicated that weed management and N levels had a significant effect on weed infestation and NPK depletion by weeds. Application of pendimethalin (PP) + oxadiargyl at 40 DAT (W3) or application of pendimethalin (PP) + 1 HW at 40 DAT or twice HW at 20 and 40 DAT alongwith 100 kg N/ha were found the equally effective treatments to reduce weed infestation and NPK depletion by weeds.
