Biogas is a clean and one of the potent renewable forms of energy which could very well substitute conventional sources of energy (fossil fuels, oil, etc.) especially in the rural sector. The later sources of energy are causing ecological–environmental problems and at the same time depleting at a faster rate. So, there is an urgency to undertake research on biogas generating potential of the biodegradable matters such as agro wastes. The present study dealt with the biogas potentiality of Castor (Ricinus communis, Euphorbiaceae) alone and in combination with cattle dung in various proportions (five treatments with three replication each) at 15 percent total solid by anaerobic digestion process as well as evaluated the manurial potential of digested biogas slurry(DBS). Five treatments including admixture in different ratio of CD and COSC -T1 (CD alone), T2 (1:2), T3 (2:1), T3 (1:1) and T5 (COSC alone) were taken for experimentation to record yield of biogas and manurial quality of corresponding digested slurry. Treatment T2 (CD: COSC in 1:2 ratio) showed a steady increase in biogas generation throughout the study period and yielded the highest amount of biogas i.e. 334.97 L/kg dry matter followed by T3 (CD : COSC in 2:1 ratio) generating 284.55 L/kg dm. All the treatments except treatment T1 (cattle dung alone) have shown the higher biogas potential than COSC alone with treatment T2, T3 and T4 produced 334.97, 284.55 and 219.30 L/kg dm of biogas respectively compared to 145.20 L biogas/kg dm of cattle dung. . The result showed that in the treatments admixed with CD and COSC (T2, T3 and T4) the treatment T2 showed highest N, P and K content (3.57, 1.46 and 1.05 % NPK respectively) while T3 (CD:COSC=2:1) showed lowest (2.65, 1.05 and 0.89 NPK respectively. The NPK content of all treatment admixed with CW and COSC were higher than the treatment having CD alone. The comparison with different manure indicated that the N and P content of DBS was higher than that of FYM, rural compost, urban compost, MSW compost and sewage sludge. The N and K content in DBS of CD and COSC admixture as compared to biogas spent sludge (BSS) of another agro material like Jatropha fruit coat and cattle dung admixture was lower by 11.19-15.35% and 47.65- 61.68 % respectively while P content was 36.36-40.38% higher |
