N2  - Agricultural practices contribute to greenhouse gas (GHG) emissions; therefore, it is essential to modify the production technologies. We analyzed decadal variation in CO2 and CH4 over a major rice cultivating area in subtropical India using GOSAT satellite data, which shows a sturdy increase. Furthermore, we carried out long- term ?eld experiments with different nutrients management in the research farm to validate CERES?Rice (Crop Environment Resource Synthesis) and DNDC (De-nitri?cation and Decomposition model) models. The variations in Global warming potential per kg rice grain production over 90 years (2005?2095) are also projected. This study used a simulation technique to predict the rice yield using CERES?Rice and GWP using the DNDC model for three varied nutrient management treatments: chemical fertilizer (CF) at full (100%) recommended level (CF100), organic fertilizer using vermicompost at full recommendation (VC100), and integration of organic and chemical fertilizer (VC50 + CF50). The CF100 treatment showed the highest rate of increase in GWP as 0.014 and 0.021 kg CO2eq kg-grain season
