ABSTRACT
The study was designed to determine the optimal mixing ratio of cattle paunch manure (PM) and cow dung (CD) in biogas production under tropical condition. The mixing ratio used were 100: 0, 75: 25, 50: 50, 25:75 and 0:100 for paunch manure and cow dung, respectively. The fermentation was carried out in five 30 litres digesters locally fabricated for 30 days. The biogas yields obtained were in the order of 50% PM + 50% CD > 75% PM + 25% CD > 100% PM + 0% CD > 25% PM + 75% CD > 0% PM + 100% CD. Thus, the optimum mixture ratio for paunch manure and cow dung obtained from this study is 50% PM + 50% CD mixture ratio with cumulative yield biogas of 76.42L/Total Mass of Slurry (TMS) within the period of study. The experimental data of all the treatments were fitted to Gompertz relation, which showed adequate fit.
