Title: Infusion of Fruit-Vegetable Waste Biomass into Bakery Sludge Vermicomposting to Enhance Nutrient Availability and Vermicompost Maturity Using Eisenia Fetida

Five vermicomposting units with varied content of Cow dung: Bakery sludge: Fruit-vegetable waste were established. Reduction in pH and total organic carbon, whereas, increase in EC, ash content and NPK was observed after vermicomposting. Micronutrients (Fe, Cu, Zn, Mn and Ni) were more but within the allowable limits. C/N ratios dropped with time. Biological parameters, viz., earthworm population, worm biomass, worm growth rate and cocoons increased progressively. Cow dung: Bakery sludge: Fruit-vegetable waste in ratio of 2:1:1 has optimum ash content, C/N ratio, seed germination and respiration rate thereby reflecting vermicompost maturity. Seed germination index (>80%) and respiration rate assessment (<120 mg CO2 kg-1VC 48h-1) confirmed the non-toxic impact of vermicomposted bakery sludge. It was inferred that fruit-vegetable waste augmented the performance of bakery sludge in vermicomposting when added in appropriate amounts.Read More
