The present work was carried out to evaluate the vermicompost of Sawdust with three different animal manures. Sawdust and animal manures such as cow manure, goat manure and poultry manure were collected and mixed separately with 1:2 ratio. The different substrate mixers were subjected to pre-decomposition for 21d. The predecomposed sawdust materials were taken in plastic troughs and introduced with microbial consortium (T1-b, T2-b and T3-b) and with adult clitellate earthworms Eudrilus eugeniae (T1-c, T2-c and T3-c) and combination with microbial consortium and earthworms, E. eugeniae (T1-d, T2-d and T3-d) of in various treatments and maintained control for all three animal manures (T1-a, T2-a and T3-a). The various physico-chemical parameters such as organic carbon, N, P, K, and C: N and C/P ratios were analysed at every 15 d interval up to 60 d.
