Abstract: The effects of media material on biogas yield was investigated using poultry (layers) drop (PD) in a laboratory and anaerobic digester. Cassava peels (CP) and obeche wood (Triplochiton Scleroxylon) were used as media material. The quantities of media material used in this investigation were 0% CP 25% CP without obeche wood, 50% CP seeded with obeche wood, 100% CP (macerated) and 100% CP (unmacerated). The waste water ratio (slurry) used in this study was 1:3. The volume of biogas produced ranged from 90-2590 cm3 with different concentration of cassava peels and obeche wood in poultry drops. Fifty percent (50% w/w) of the Cassava peels seeded with obeche wood in poultry dropping yielded the highest volume of biogas (2590 cm3). The wood medium used (obeche) exhibited good medium characteristics in accelerating biogas yield.
