Effect of intermittent irrigation on CH_4 emission from an Indonesian paddy field with plots subjected to the application of various types of fertilizer was studied. Intermittent irrigation treatment was conducted once a week from immediately before heading time to harvest time. The mean CH_4 emission rates (mg CH_4 m^<^2>h^<-1>) during the intermittent irrigation period were in the ranges of 26.6-29.0 and 20.6-27.6 for the chemical fertilizer plots with continuous flooding and intermittent irrigation, respectively. They ranged from 17.9 to 29.0 and 25.2 to 31.7 for the plots treated with both urea and organic materials. These rates were similar to those observed in the same field under continuous flooding during the rainy season cultivation. Thus, the effects of intermittent irrigation were not significant in the paddy field studied. The total amount of CH_4 emitted (g CH_4 m^<-2>) throughout the growth period was 36-45 and 29-44 for the chemical fertilizer plots with continuous flooding and with intermittent irrigation, respectively, while 32-50 and 43-47 from the plots amended with organic materials.
