The field and laboratory experiment was carried out during kharif, 2005 to know the methane emission as influenced by different crop establishment techniques and organic manures. The experiment involved three crop establishment techniques viz., Transplanting, System of rice intensification (SRI) and Aerobic and four sources of nutrients viz., recommended NPK, in-situ green manure (Sunnhemp) + Rec. NPK, paddy straw manuring + Rec. NPK and FYM + Rec. NPK. The SRI establishment technique recorded significantly higher methane emission during early stages of crop growth (40 and 50 DAS). The methane emission under aerobic establishment technique was lower than normal transplanting during early stages (40 and 50 DAS). During early stage of crop growth (30 DAS), application of FYM with recommended NPK recorded significantly higher methane emission. At later stages, incorporation of paddy straw with recommended NPK recorded higher methane emission.
