Abstract:
An investigation entitled, “Bioremediation of methane emission using methanotrophic bacteria in paddy” was undertaken during kharif, 2022-23 at experimental farm, department of Soil Science and Agricultural Chemistry, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth Dapoli, Dist. Ratnagiri. The field experiment was laid out in the factorial complete randomized design, consisting 16 treatment combinations comprising two factors i.e. four different nutrient source viz, control, recommended dose through chemical fertilizer, recommended dose through konkan Annapurna briquette and gliricidia application and four different methanotrophic consortium viz, control, type I, type II, and type Ib which were replicated three time to study the effect of different nutrient source and methanotrophic bacteria on growth parameters. The significantly highest growth attributes viz. number of tillers, plant height and number of panicles were recorded highest in the treatment were recommended dose of fertilizer 100:50:50 N: P₂O₅:K₂O kg ha^-1 was applied using straight fertilizer.
