Objectives: The objective of the present study was to analyse the efficiency of fodder beet and napier grass as a substrate for biogas production. Methods/Analysis: Proximate (total solids, volatile solids, ash, total organic carbon) and chemical (cellulose, hemicellulose, lignin and silica) analysis of fodder beet and napier grass PBN233 (fresh and digested form) was done to analyse the composition of substrate which affects biogas production. Biogas production studies were conducted following single phase digestion in 2 litre capacity biogas digesters. Percent nitrogen was also estimated in fodder beet and napier grass. Findings: Digested form of fodder beet and napier grass, which is generally wasted, was found to produce 102.9 litre biogas/kg volatile solids and 92.4 litre biogas/kg volatile solids, respectively. Novelty/Improvement: The present study has explored the comparative potential of fodder beet and napier grass PBN233 as a substrate for biogas production.
Keywords: Biogas Production, Digested Form, Fodder Beet, Fresh Form, Napier Grass PBN233
