This data has been obtained through the study on evaluation of methane emission in rice ecosystem under flooding and AWD water management. At the first week after 1 - 7 DAS, CH₄ fluxes is almost same but have a significant drop in CH₄ emissions from AWD was identified during the drying period with lagged emissions again after re-flooding (water refill). The gradual increase in CH₄ emissions from flooded was observed only after about 40 - 50 days after transplanting. During Nitrogen fertilizer application, CH₄ fluxes was increase at all split but as mention above lagged emission again after re-flooding on AWD irrigation after fertilizer application. On AWD at 12 – 20 DAS showed higher CH₄ fluxes from other DAS. In the end of planting season, reducing of flooding for harvesting cause CH₄ fluxes also reduce. The cumulative CH₄ fluxes over growing season showed significantly different between flooded and AWD where cumulative fluxes at flooded is the highest. The significantly increasing of cumulative fluxes on flooded condition is when N fertilizer applied. AWD showed 57% of cumulative CH₄ fluxes reduction.
