Abstract

By using Lumbricus rubellus, vermicomposting started after 3 weeks of pre composting. Five treatments in different ratio of cow dung : spent mushroom substrate were prepared as feed materials with four replicates for each treatment namely; 80:20 (T1), 60:40 (T2), 50:50 (T3), 40:60 (T4) and 20:80 (T5). After 7 weeks of vermicomposting, macronutrient elements of vermicompost produced were measured and the process continues with composting when all the earthworms were taken out from the treatments. Macronutrient elements of compost produced were also measured after 20 weeks of composting. The data reveals that 7 weeks for vermicomposting of cow dung and spent mushroom substrate is sufficient to produce good vermicompost rather than continuing process with 20 weeks of post composting. Therefore, it can be concluded that the duration and quality of vermicomposting is better than composting particularly in vermicompost production.
