This study aims to assess the effect of rice husk biochar, raised beds, and chicken manure on the CO2 flux and shallot production on peatland. This study adopted a factorial randomized block design with three factors and three replications. The P1 treatment was recommended by the Swamp Land Agricultural Research Institute by adding chicken manure (5 ton ha−1) and rice husk biochar (5 ton ha−1) while the P2 treatment was recommended by the Vegetable Research Institute by adding chicken manure (10 ton ha−1). The raised beds heights were 20 cm (A) and 30 cm (B). Variance analyses were applied to each observation variable and followed by Duncan's Multiple Range Test at a 5% level. The P1A treatment was the best in improving the shallot production up to 10.88 tons and producing the lowest CO2 cumulative flux up to 0.158 ton ha-1 season-1.
