AB  - Rice cultivation during four planting seasons by using cultivation system improvements, especially in the management provision of water and fertilizer, other than increasing rice production can also reduce methane emission which is often rumored as a cause of global warming. Efforts to reduce methane emission from paddy fields must be done because of the impact of ecological damage caused by climate change due to global warming. It is estimated that by the year 2100 the average surface temperature of the earth will increase up 2 to 3° C. The experiment was conducted in the village of Purbaganda, Pematang Bandar District, Simalungun over four planting seasons from July 2011 until June 2012. The research design used in the study was split plot design which was organized into groups based on the difficulty of obtaining an ideal environmental uniformity in the field. Watering System treatment as main plot factor (A) and fertilization as subplot factor (B), with three replications. The treatments in the main plot were intermittent and continuous irrigation system, conducted to determine the amount of methane emissions in each planting season. For subplot, the fertilization treatments were based on laboratory analysis of soil, and Fertilization Recommendation of the Minister of Agriculture regulation No. 40 OT.140/2007. These were then combined with probiotic fertilization. The results showed that the pattern of methane emission varies in each treatment. The average methane emission was highest in treatment A1B1 with 338.50 kg ha-1 per season, and lowest in A2B6 treatment with 63.25 kg ha-1 per season. A2B6 treatment that used fertilization according to laboratory analysis with probiotic fertilization experienced intermittent irrigation process.  The higher dosage of fertilizer N in treatment A1B1 led to higher methane emission than treatment A2B6.
