A field experiment was conducted to find out best weed management practices in onion (Allium cepa L.,) during rabi 2011-12 and 2012-13. The experiment was laid out in Randomized block design with three replications. The experiment consisted of pendimethalin, oxyflourfen as pre emergence herbicides and Imazethapyr and Quizalofop ethyl as post emergence herbicides and their combination thus forms 10 treatments along with Weedy check. Application of pendimethalin and oxyflourfen supplemented with Quizalofop ethyl @ 75 g a.i / ha as post emergence found to be on par with hand weeding thrice on increasing no. of leaves, LAI, plant dry matter and bulb yield. Imazethapyr @ 100 g a.i / ha as post emergence application (20 DAT) coupled with pre emergence herbicides produced the lower values than weedy check (T10) as Imazethapyr found to be toxic to the Onion.
