Abstract: A field exjleriment was conducted during two consecutive kharif seasons to identify an effective weed management practice in urdbean. Cynodon dactylon, Dactyloctenium aegyptium, Cyperus rotundus, Cleome viscosa and Physalis minima were the dominant weeds . Integration of pendimethalin 30 EC at 0.75 kg/ha as pre-emergence with one hand weeding at 40 DAS showed superiority with rbgard to weed management and yield improvement over the other weed management treatments. Sole application of pendimethalin 30 EC at 1.0 kg/ha also proved to be effective. Though normal seed rate outyielded any increase in seed rate(mean of two years), it remained at par with 30% higher seed rate. Season-long weed competition caused an average yield reduction of 35.82% as compared to integrated weed management.
