Biogas is a renewable source of energy, generally a mixture of methane and carbon dioxide which are naturally released when organic materials including aquatic weeds, agricultural residue, animal waste, food waste etc. decomposes under anaerobic conditions. The experiment was conducted under two conditions viz. room temperature and poly- house temperature and included four treatments T1 (Dal weed 100%), T2 (Dal weed+agricultural residue), T3 (Dal weed+food waste) and T4 (Dal weed+agricultural residue+food waste) with four replications for each treatment and statistically designed as Completely Randomized Design (CRD) to investigate biogas production. The maximum methane production was observed in T1 (531.25 mL kg-1) and T4 (436.25 mL kg-1) under poly-house and room temperature, respectively. However, the increase of pH, TS, VS and total nitrogen caused a corresponding increase in biogas production. Whereas, the decrease in ammonium nitrogen, total phosphorus, and COD triggered an increase in the production of biogas.
