                         (CH4) emissions. In southern Brazil, rice is grown in lowland 
                         flooded areas once a year, followed by a long fallow period. This 
                         study aimed to measure CH4 fluxes in a rice paddy field in 
                         southern Brazil during the rice-growing season of 2015/2016 and 
                         the following fallow period. The fluxes were estimated using the 
                         eddy covariance (EC) technique and soil chamber (SC). Diurnal and 
                         seasonal variations of CH4 fluxes and potential meteorological 
                         drivers were analyzed. The CH4 fluxes showed distinct diurnal 
                         variations in each analyzed subperiod (vegetative, reproductive, 
                         pre-harvest, no rice, and land preparation), characterized by a 
                         single-peak diurnal pattern. The variables that most influenced 
                         methane emissions were air and surface temperatures. In the 
                         growing season, the rice vegetative stage was responsible for most 
                         of the measured emissions. The accumulated annual emission 
                         estimated was 44.88 g CH4 m\−2 y\−1, being 64% 
                         (28.50 g CH4 m\−2) due to the rice-growing season and 36% 
                         (16.38 g CH4 m\−2) due to the fallow period. These results 
                         show the importance of including fallow periods in strategies to 
                         mitigate methane emissions in flood irrigated rice-growing 
                         areas.",
