Abstract: Vermicomposting application also helps in cost effective and efficient recycling of animal wastes, agricultural residues and industrial wastes into valuable nutrient rich product, namely vermicompost. The aim of this study was poultry droppings (PD) was mixed with rice husk (RH) and sugarcane press mud (SPM) at various proportions and kept for natural stabilization for 15 days and subsequently vermicomposted using native species Perionyx ceylanensis for a period of 75 days under laboratory conditions. P. ceylanensis was inoculated at the rate of 20g kg-1 of above waste combination. The data revealed P. ceylanensis have good biomass increase and cocoon and hatchlings production in all vermicomposting treatments except the treatment with PD alone. Among the different treatments VCPT2, VCPT3, VCPT6 and VCPT7 treatments were better than other studied treatment combinations. The earthworm mortality was higher in treatments those contained more PD proportions. Hence, it can be concluded that among the treatments, equal proportions (1:1:1) of PD, SPM and RH and/or equal proportion of PD and PM is best substrate medium for growth and reproduction of P. ceylanensis and also large scale vermicompost production.
