In this study we investigated the effect of urea concentration on bio-digestion of cassava peels. Five 1L digesters with a working volume of 750 ml labeled U1(control),U2,U3,U4 and U5 were charged with 42.7g of peels and respectively increasing amount of urea, 0.00% control),0.01 %; 0.03%; 0.04 % and 0.05%, anaerobic digestion was conducted for 14days under mesophilic conditions. The cumulative biogas yield decreased in the order U2>U3>U1>U4>U5 with 80.79, 50.01, 49.186, 25.71 and 1.23L/Kg TS respectively. The highest biogas (80.79L/KgTS) yield was obtained in digester U2 with 0.01% of urea. When compared our results with literature, urea can be a good supplement for enhancing biogas production
