The experiment was conducted at Jorhat in Assam of India during autumn season of 2017 and 2018 to investigate the methane emission from transplanted rice through irrigation and fertilizer management practices. The treatment consisted of four irrigation schedules viz., continuous submergence, 5 cm irrigation at 3 days after disappearance of ponded water (DADPW), 5 cm irrigation at 5 DADPW, 5 cm irrigation at 7 DADPW and four fertilizers management practices viz., control, compost @ 5 t/ha, integrated nutrient management (INM) and recommended dose of fertilizers (RDF). Results revealed that highest methane emission and cumulative methane flux (CMF) were recorded in continuous submergence plot. Amongst the fertilizers management practices, application of RDF recorded the highest methane emission and CMF. Application of 5 cm irrigation at 3 DADPW with RDF recorded the highest grain and straw yield in both the years. The treatment receiving continuous submergence with RDF recorded the highest seasonal methane flux.
