Vermicomposting is a simple environment-friendly technology that supportssustainable agriculture and waste management
programs. It involves physical and biochemical action of earthworms in converting organic materials (usually wastes) into two
useful products- the earthworm biomass and high quality organic fertilizer, the vermicompost. The efficiency of
vermicomposting may be measured by the worm number and/or biomass and the vermicompost produced. To achieve high
efficiency one of the keys is selection of proper substrate which is composed of bedding material and food source for the worms.
A 3x3 factorial experiment with plant matter and animal manures as the factors was conducted to determine the efficiency of
vermicomposting as indicated by worm biomass vermicompost produced. Data on worm number and weight, and vermicompost
produced were collected and analyzed. A sample of vermicompost from each treatment was brought to soil laboratory for NPK
analysis. It showed that the sawdust, among the plant materials, and hog manure, among the animal manures were the
bestmaterials for vermicomposting substrate. The worm numberand total weight were highest in this combination. The
individual weight and concentration of nutrients NPK were highest in G. sepium and chicken manure substrate. It is concluded
that efficiency of producing worms and vermicompost is affected by the substrate materials and that it could be increased by
selecting appropriate substrates.
