AbstractThe objective of this study was to determine the capacity of Lumbricus rubellus, Eisenia fetida and Eudrilus eugeniae earthworms in vermicompost production utilizing mushroom waste substrate based on weight; number and weight loss of earthworms; temperature; pH; moisture content of media; and C/N ratio. The results showed that, by using 42 g of E. eugeniae, E. fetida and L. rubellus earthworms, there was an increase in weight of earthworms and vermicompost by more than 300% and 75%, respectively. In general, these three species of earthworms were able to produce vermicompost in compliance with quality standards, showing C/N ratio lower than 20.

The present work has assessed sustainable vermiconversion of aquatic weed water hyacinth (Eichornia crassipes). The garden soil, water hyacinth and cow dung were taken in the following the combinations of 1: 2 : 1, 2: 1: 1 and 1 : 1: 2. Two species of earthworms Eudrilus eugeniae and Eisenia fetida was used for the experiment. The total nitrogen (0.18% in control and 1.68% in earthworm treated) and phosphate (0.63 % in control and 1.64 % in earthworm treated) levels were increased and toxic heavy metals zinc (7.66 ppm in control and 2.58 ppm in earthworm treated) and copper (6.68 ppm in control and 1.15 ppm in earthworm treated) were significantly decreased. The earthworm enriches the compost with various nutrients for plant and microbial growth. Plant growth studies were conducted in all the combination of water hyacinth, maximum growth of root length (8.9cm and 7.2 in control) and shoot length (21.6cm and 16.2 in control) observed compare to control. Gut microbial analysis revealed that Bacillus cereus, Micrococcus luteus were predominantly present in the earthworm. The study recommended that the aquatic weed compost was suitable of agricultural usage.
