## Abstract
Mitigation of CH 4 emission of rice field is becoming a serious issue. The Agricultural Environment Preservation Research Station in Central Java conducted a field study to investigate the effect of water regime and soil tillage on CH 4 emission from paddy fields. Treatments consisted of two factors. The first factor was water regime, e.g ., 1) continuously flooded 5 cm, 2) intermittent irrigation and 3) saturated water condition at 0-1 cm water level. The second factor was soil management, e.g. , 1) normal tillage, 2) zero tillage + 3 sulfosate ha -1 and 3) zero tillage + 3 L paraquat ha -1 . Most of treatments gave a significant reduction of total CH 4 emission between 34 – 85% during the wet season crop as compared to normal rice cropping practice, while in the dry season the CH 4 reduction ranged between 16 – 92%. No-tillage with non-selective herbicides combined with intermittent/saturated irrigation system significantly reduced methane emission without significantly affecting rice productivity as compared to normal tillage with continuous flooding (farmers practice)
