Summary of the treatment (i.e., bare soil and with plants) effect on season-long methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) emissions and several global warming potential (GWP) parameters over the course of the 2019 growing season from furrow-irrigated rice under no-tillage management on a silt-loam soil in east-central Arkansas. Global warming potentials were evaluated using CH4 and N2O conversion factors from both the 5th (IPCC, 2014) and 6th (IPCC, 2021) Intergovernmental Panel on Climate Change assessments.
