Vermicompost was prepared by five different treatments from relatively resistant coconut husk mixed with either pig slurry or poultry manure. The recovery of vermicompost varied from 35% to 43% and it resulted in significant increase in pH, microbial biomass carbon, macro and micro nutrients concentration. Among the treatments highest relative N (1.6) and K (1.3) recovery were observed for 20% feedstock substitution by pig slurry while poultry manure substitution recorded highest P recovery (2.4). Compost maturity parameters significantly differed and well correlated. The characteristics of different treatments established the maturity indices as C/N 15-20; Cw < 1.8; Cw/Norg < 0.55; Lignin < 10-12; CHA/CFA > 1.5 and HI > 15.0. The manurial value of the coconut husk compost was improved by feedstock substitution with pig slurry (80: 20). The results revealed the technical feasibility of converting coconut husk into valuable compost by feedstock substitution with pig slurry. (C) 2016 Elsevier Ltd. All rights reserved.
