Abstract;In order to control the methane emission of rice paddy fields, the authors compared both the watering irrigation plot and the conventional plot with respect to methane fluxes. Watering irrigation was done from the 8th day(Tachikawa-machi) and the 11th day(Yamagata University Farm) after rice transplanting, until mid summer drainage. The results obtained are as follows. 1. In both rice paddy fields in Tachikawa-machi and Yamagata University Farm, the methane emission in the watering irrigation plot was about half as much as that in the conventional plot. 2. A yield of rice in the watering irrigation plot was about the same as much as that in the conventional plot in both rice paddy fields. For the reasons mentioned above, the method of water management, that is watering irrigation after rice transplanting, was exceedingly effective in order to control the methane emission of rice paddy field. Studied method did not reduce production, but it could control about half methane emission. (author abst.)
