Nitrous oxide and methane emission from a flooded rice field as influenced by separate and combined application of herbicides bensulfuron methyl and pretilachlor

► Bensulfuron methyl or pretilachlor individually can reduce N2O and CH4 emission from 2 flooded rice soil. ► Combined application of herbicides at normal dose can keep the 3 emission at a lower level. ► Combined application provides significantly higher grain yield 4 as compared to the herbicides applied alone.
