The potential of spent mushroom substrate from saw dust in vermicomposting were found out through the growth and reproduction of earthworms including the nutrient elements of vermicompost produced at the end of vermicomposting. 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 3 weeks of pre-composting followed by 7 weeks of vermicomposting, T4 showed the highest percentage of growth and reproduction where mean of earthworms’ numbers increases (M = 295.00, SD = 17.32, …

Vermicomposting using Lumbricus rubellus for 49 days was conducted after 21 days of pre-composting. Three different combination of treatments were prepared with eight replicates for each treatment namely cow dung : kitchen waste in 30:70 ratio (T1), cow dung : coffee grounds in 30:70 ratio (T2), and cow dung : kitchen waste : coffee grounds in 30:35:35 ratio (T3). The multiplication of earthworms in terms of numbers and weight were measured at the end of vermicomposting. Consequently, only T2 showed significant increase (from it initial stage) compared to other treatments. The presence of coffee grounds in T2 and T3 showed …
