Abstract :

The field experiment was conducted during the Kharif season of 2009-2010 at Crop Research Center farm at SardarVallabhbhai Patel University of Agriculture & Technology, Modipuram, Meerut (U.P.) to, Refining the weed management practices to increase the yield of urd bean (Vigna mungo L.) in north-western India. Tenth treatments (weedy check, one hand weeding at 20 DAS, two hand weeding at 20 and 40 DAS; quizalofop ethyl @ 50 g ai/ha as post- emergence, pendimethaline @ 1 kg a.i/ha as pre-emergence, oxyflourfen @ 100 g a.i/ha as pre-emergence, pendimethaline @ 1 kg a.i/ha as pre-emergence + quizalafop ethyl @ 50 g a.i/ha as post-emergence, oxyflourfen @ 100 g ai/ha as pre-emergence + quizalofop ethyl @ 50 g ai/ha post-emergence, pendimethaline @ 1 kg ai/ha as pre-emergence + one hand weeding at 40 DAS, oxyflourfen @ 100 g ai/ha as pre-emergence + one hand weeding at 40 DAS were tested in Randomized Block Design with four replications. Growth and yield attributes were affected significantly due to different weed management practices. However, weed density and weed dry weight were decreased significantly with increasing number of hand weeding (20 and 40 DAS). Hand weeding at 20 and 40 DAS proved its superiority over other methods of weed control in respect of all the growth characters and yield attributes as well as grain and straw yield of urd bean crop followed by oxyfloufen @ 100 g ai/ha as pre-emergence + one hand weeding at 40 DAS.
