—In order to quantify the methane emission from paddy fields with different irrigation methods and to study the potential of using the alternate flooding strategy in suppressing the methane emission, field experiments were conducted in Nestlé Rice Experimental Station located in Sik area, Kedah, Malaysia. Closed-chamber method was used in this research study. By employing transparent chambers, methane gas was sampled from two paddy field plots with different irrigation methods. The methane gas was collected at the paddy plots and analyzed for its concentration. It was done continuously for 84 days after seeding stage and stopped before the ripening stage of paddy. The similar increasing trend of methane emission was observed from each paddy field plot from the tillering stage till flowering stage of paddy. However, the methane emission rate from non-flooded plot with the water saving irrigation method was found relatively low compared to the flooded plot.
