A field experiment was carried out during Kharif 2014 to find out practically convenient and economically feasible weed management practice in onion at Krishi Vigyan Kendra, Patiala. Different combinations of hand weeding with application of Pendimethalin 30 EC @ 1875ml/ha (pre-planting) and oxyfluorfen 23.5 EC @ 950ml/ha (postemergence) were used in onion variety ‘Punjab Naroya’. Weed free check treatment (three hand weeding at 20, 40 and 60 DAS) recorded significantly lowest weed density, dry weight of weed and higher weed control efficiency. All the growth attributes of onion viz., plant height, neck thickness, bulb weight and bulb diameter were recorded maximum in weed free. This treatment also recorded highest bulb yield and gross monetary return per hectare, however maximum B:C ratio was observed in treatment pendimethalin 30 EC @1875ml/ha (PP)+ Oxyfluorfen 23.5 EC @ 950ml/ha (POE)+ One hand wedding at 40 DAS.
