Industrial lignocellulosic waste was amended with other organic supplements (saw dust and cow dung); and three types of vermibeds were prepared: guar gum industrial waste+cow dung+saw dust in 40: 30: 30 ratio (T1), guar gum industrial waste+cow dung+saw dust in 60: 20: 20 ratio (T2,), and guar gum industrial waste+cow dung+saw dust in 75: 15: 10 ratio (T3). As compared to initial concentrations, vermicomposts exhibited a decrease in organic C content (5.0-11.3%) and C:N ratio (11.1-24.4%) and an increase in total N (18.4-22.8%), available P (39.7-92.4%), and exchangeable K (9.4-19.7%) contents, after 150days of vermicomposting. A vermicomposting coefficient (VC) was used to compare of vermicomposting with the experimental control (composting). P. sansibaricus exhibited maximum value of mean individual live weight (742.8±21.1mg), biomass gain (442.94±21.8mg), growth rate (2.95±0.15mg day−1), cocoon numbers (96.0±5.1) and reproduction rate (cocoons worm−1 day−1) (0.034±0.001) in T2 treatment. In T3 maximum mortality (30.0±4.01 %) in earthworm population was observed. Overall, T2 vermibed appeared as an ideal substrate to manage guar gum industrial waste effectively. Vermicomposting can be proposed as a low-input basis technology to convert industrial waste into value-added biofertilizer.
