The weed density at 20 days after sowing was increased significantly upto 40 kg N ha", whereas at 60 DAS they were significantly counted maximum only at 20 kg N ha". Weed dry weight at harvest was not influenced due to increasing levels of N. Significantly the higher seed yield and yield attributes were recorded under the application of 60 kg N ha·'. Pre-etn~rgence application of oxadiazon at 0.5 kg ha" was most effective in controlling weeds which enhanced growth and yield components and resulted in production of higher coriander seed yield (2599 kg ha") and net monetary return of Rs. 42354. This treatment was at par with pendimethalin. The interaction effect of N and weed management treatments were not significant.
