Vermiculture is a sustainable method for managing organic waste, enhancing soil fertility, and supporting crop production, with earthworms play a crucial role in decomposing organic matter and promoting soil health. This study examined whether the addition of probiotics, including Lactobacillus sporogenes, vital microorganisms, and Saccharomyces cerevisiae, accelerates the ver-micompost process and improves nutrient levels in compost. Organic wastes such as cow manure, leaf litter, floral debris, and onion-garlic refuse were used in four sub-experiments set up for each waste type incorporating probiotic supplements. Chemical parameters, including pH, alkalinity, hardness, chloride, sulphate, nitrate, iron, and organic matter, were analysed using standard methods. Results showed a pH range of 6-7, with maximum hardness observed in the flower waste + L. sporogenes group at 60 days, and a minimum of 716 mg/g in leaf litter at 90 days. Groups with 5. cerevisiae recorded the highest chloride levels in cow manure, leaf litter, and floral waste, while onion-garlic waste showed lower chloride levels. Sulphate, nitrate, and iron were highest IN flower waste, and leaf litter had the highest organic matter content at 30 days. Chemical parameter levels generally peaked at 30 days, slightly decrease at 90 days, slightly below the initial peak. Three replicates were maintained for each experimental group, revealing variable chemical profiles over 30, 60, and 90 days. These findings highlight probiotics potential to optimise vermicomposting and improve compost quality
