In the year 2018 and 2019, a field trial on wheat was performed in the Rabi season. The experiment was laid out in split plot design and replicated thrice. The nitrogen scheduling includes N1- ½ basal + ¼ at 4WAS + ¼ at 8 WAS, N2 -⅓ at 4 WAS + ⅓ at 8 WAS + ⅓ at 10 WAS, N3 -¼ at 4 WAS + ¼ at 6 WAS + ¼ at 8 WAS + ¼ at 10 WAS while weed management treatment were W2 -clodinafop @ 60 g/ha, W3 -sulfosulfuron @ 25 g/ha, W4 -carfentrazone @ 20g/ha along with weed free and weedy check. The results revealed that the lowest weed density, dry matter accumulation, weed index, maximum weed control efficiency and yield were recorded under W3- sulfosulfuron @ 25 g/ha which was at par W4- carfentrazone @ 20 g/ha and found significantly superior over W4- clodinafop @ 60 g/ha. N3 -¼ at 4 WAS + ¼ at 6 WAS + ¼ at 8 WAS + ¼ at 10 WAS + W3 -sulfosulfuron @ 25 g/ha recorded significantly maximum which was significantly superior at 30 and 60 DAS over all the treatments during both the year of experimentation.

On the basis of results summarized above, it can be concluded that the application of N3 -¼ at 4 WAS + ¼ at 6 WAS + ¼ at 8 WAS + ¼ at 10 WAS + W3- sulfosulfuron @ 25 g/ha gave best results in respect to all the weed and yield parameters and second-best treatment was N3 -¼ at 4 WAS + ¼ at 6 WAS + ¼ at 8 WAS + ¼ at 10 WAS + W4- carfentrazone @ 20 g/ha during both the year of experimentation.
