Vermicomposting is a way of comprehensive interactions between the organic matter, microorganisms, earthworms and other soil invertebrates consequence in the breakdown, biooxidation and stabilization of organic matter. This process not only converts waste into valuable product but also diminution the size of waste. In present study floral waste was taken as a raw material and processed through Vermicomposting method with and without cattle dung. The Process carried out with different compositions of floral waste (FW)-cattle dung (CD) mixtures under aerobic condition in a plastic bins to find the rate of depletion of biomass. The initial substrate depth of five different compositions viz. 100% FW, 75% FW, 50% FW, 25% FW and 100% CD were 25cm, 16 cm, 13 cm, 11 cm and 8 cm which were depleted 80% ± 1 , 68% ± 1,61% ± 1,54% ± 1 and 25% v respectively. The rate of biomass reduction was higher in summer season followed by winter season and rainy season. Obtained result also explored that first twelve days in every season, biomass reduction rate was highest while last 10 days this rate was very slow. The time for substrate stabilization during vermicomposting was also found to be lesser in summer as compared to rainy season. The substrate depth variation with respect to time followed a declined curve.
