Analysis of variance summary of the effects of cultivar, water management, time, and their interaction on methane fluxes and the effects of cultivar, water management, and their interaction on pre- and post-flood-release and season-long, area-scaled and yield-scaled methane emissions during the 2015 growing season at the Rice Research and Extension Center near Stuttgart, Arkansas.
