Abstract
An integrated weed management study on onion (Allium cepa L.) was conducted in two consecutive kharif sea- sons of years 2010 and 2011 in a randomized block design with 9 treatments, having combinations of hand weed- ing with application of pendimethalin @ 1.0 kg/ha pre-plant incorporation (PPI) and oxyfluorfen @ 0.250 kg/ha post-emergence (PoE). Weed management with three hand weedings (HW) at 20, 40 and 60 DAT recorded sig- nificantly lowest weed density, dry weight of weeds and higher weed control efficiency and maximum in all the growth and yield attributes of onion viz. plant height, neck thickness, bulb weight, bulb diameter and bulb yield. Highest net monetary returns ( 110.3 103/ha) and B:C ratio (2.76) were obtained with the application of pendimethalin @ 1.0 kg/ha (PPI) + oxyfluorfen @ 0.250 kg/ha (PoE) + One hand wedding at 40 DAT, which was found practically more convenient and economically feasible weed management method in onion.
