The paper investigates the effects of the quantity of media materials with simple appraisal on biogas yields between hard and soft wood subjected to the same atmospheric condition in the Ado-Ekiti, Nigeria, between October 2009 and June 2010. Sixteen digesters were used and the mechanical grinding of cassava peels was done in a clean mortar and pestle. Specific grammes of cow dung and cassava peels (200 g, 150 g, 100 g and 50 g) were seeded with four substrates (woods) mixed up with 1200 cm³ of distilled water respectively. The appropriate ratios of the prepared slurries were transferred into different digesters for bio-degradation process which is third-fourth full with the aid of a funnel, and the tubes were passed into a measuring cylinder as a gas collector inverted over acidified water in a plastic vessels. The volume of biogas produced ranged from 6964 cm³ to 13,185 cm³ by Mahogany, and Iroko ranged from 5340 cm³ to 10,250 cm³ were obtained for both hard woods used. Likewise, the volumes of gas produced by soft woods were from 2465 cm³ to 6445 cm³ by Obeche and 3430 cm³ to 6990cm³ by Araba. The results showed that, the highest percentage of the seedling media materials (33% each) on the substrates (cassava peel and cow dung) produced the highest biogas with 2800 cm³ of Mahogany, 2400 cm³ of Iroko, 1200 cm³ of Araba and 1130 cm³ of Obeche woods respectively. It was established that, the rate of biogas yields is directly proportional to the quantity of the seedling materials to obtain a reliable results as an alternative renewable energy.
