Studies on diurnal variations of greenhouse gas (GHG) fluxes in rice (Oryza sativa L.) production systems have been limited to flooded, or variations of flooded, soil conditions. This study aimed to quantify hourly CO₂, CH₄, and N₂O fluxes over a period of 20 hours and the effects of site position (up-, mid-, and down-slope) and tillage practice [conventional tillage (CT) and no-tillage (NT)] during the vegetative lag phase in a furrow-irrigated rice field on a silt-loam soil in eastern Arkansas.
