chemical application, one of the most important crop management processes happened to cause spray drift, that would threaten farmers in field as well as dwellers in rural region. Spray drift was affected by micro-meteorological parameters. A study to evaluate short distance drift characteristics of a boom sprayer in paddy fields has been undergoing. This study is the first step of the research. Main purpose of this study to evaluate the effect of atmospheric stability on turbulence structure above and within a rice canopy. As atmospheric stability increased turbulence intensity decreased, kurtosis and skewness became closer to those of normal distribution. Effect of atmospheric stability was detectable above and within a rice canopy but it was not clear at the canopy height.
