Abstract

Biogas production on supplementation of paddy straw to cattle dung under semi-continuous system was carried out at 14-15% total solids concentration under laboratory conditions. Supplementation of 5% paddy straw to cattle dung led to maximum biogas production of 53.7 l/kg with volumetric productivity of 0.460 l/l/day accompanied by 24.0 and 26.4% degradation of total and volatile solids respectively. The C/N ratio of effluent slurry after 5% paddy straw supplementation to cattle dung was 30.7 that reduced to 21.9 on composting with  Trichoderma reesei for one month resulting in the production of quality manure.
