Rice cultivation is being focused as a prime contributor to climate change due to the release of greenhouse gases into the atmosphere. In aspect to study the reduction of the GHGs emission, experiment trial was conducted with eight different soil amendment combinations viz., recommended dose of Fertilizers (RDF), fly ash, Biochar, Gypsum, Silica Solubilizing Bacteria (SSB), fly ash + SSB, Biochar + SSB, Gypsum + SSB. Gas collection was done at different crop growth stages using open bottom chambers and analyzed with Shimadzu GC-2014 gas chromatograph. Methane emission was observed less in applications of Fly ash (40.5 kg/ha), Fly ash + SSB (43.7 kg/ha) and Gypsum + SSB (45.5 kg/ha). Low levels of nitrous oxide emission were seen in applications of Fly ash + SSB (2.1 kg/ha), Gypsum + SSB (2.2 kg/ha) and Fly ash (2.2 kg/ha). Higher nitrous oxide and methane emission was found with the treatments of RDF, SSB, Biochar, Gypsum and Biochar + SSB. From the study, it was concluded that application of fly ash + SSB and fly ash did reduce the GHGs emissions on higher percentage over the application of other soil amendments in rice field.
