Abstract: A study was conducted to evaluate the green house gas (CH4 and N2O) emission potential of some rice-based triple cropping systemspracticed in India. Four cropping systems were studied along with rice-rice system (control) in a randomized block design with three replicatesof each. Methane emission was significantly higher from all the plots during wet season. Significantly higher annual methane flux recordedfrom the rice-rice rotation system (289.54 kg ha-1). During the dry season higher N2O emission recorded from the rice-rice rotation systemwith pulses of N2O flux after the N-fertilizer application. Significantly lower CH4 emission per Mg grain yield recorded from the rice-maizepigeonpeasystem (0.89kg ha-1) while rice-rice rotation system recorded highest (31.30kg ha-1). Study revealed that rice based croppingsystems can reduce the greenhouse gas emission significantly while increasing the yield from rice cultivation.
