Table 2: Analysis of variance summary of the effects of tillage, site position, and their interaction on the difference in soil volumetric water content (Diff-VWC) in the top 6 cm between inside and outside gas sampling base collars separately among 10 and 15 weekly sample dates in 2018 and 2019, respectively, and end-of-season above ground dry matter and yield under furrow-irrigated rice production during 2018 and 2019 at the Rice Research and Extension Center near Stuttgart, AR. Bolded values were considered significant at the 0.05 level.
