Global warming associated with emissions of greenhouse gases (GHGs) is one of the most important environmental issues because its potential to impact on human life is severe. In this study, we investigated the effect of organic matter applications and water management on the fluxes of GHGs and yields of rice from paddy fields, a major source of anthropogenic CH₄ emissions. We found that the treatment effects on fluxes of GHGs differed among the gases and that the treatments affected rice yields. High CH₄ fluxes and high rice yields were associated with organic matter amendments. CH₄ gas fluxes were high during summer season especially in manure compost plot. Maintaining low water levels resulted in low rice yields and low emissions of CH₄. CO₂ is sunk into the soil through rice crop during daytime under any water management in this experiment.
