A field experiment was conducted during Kharif season 2022 and 2023 at Agronomy research farm, Acharya Narendra Deva University of Agriculture and Technology Kumarganj, Ayodhya Uttar Pradesh, (India). The experiment was laid out in split plot design with thrice replications. Taking three nitrogen levels 80 Kg/ha, 120 Kg/ha and 160 Kg/ha in main plot and five weed management practices Pyrazosulfuron ethyl 10 % WP @ 20g a.i/ha (PE) at 0-3 DAT, Bispyribac sodium 10 % SC @ 25g a.i/ha (PoE) at 25 DAT, Pyrazosulfuron ethyl 10 % WP @ 20g a.i/ha (PE) at 0-3 DAT fb Bispyribac sodium 10 % SC @ 25g a.i/ha (PoE) at 25 DAT, Weed free and Weedy check in subplot. Results revealed that significantly higher crop growth rate, relative growth rate, and net assimilation rate and grain yield was recorded in 160 Kg N ha-1 and Pyrazosulfuron ethyl 10 % WP @ 20g a.i/ha (PE) at 0-3 DAT fb Bispyribac sodium 10 % SC @ 25g a.i/ha (PoE) at 25 DAT which was comparable to weed free during both the years of investigation on transplanting rice.
