Abstract: Introduction: This study aimed to enhance the biodegradation of groundnut shells through pre-digestion with selected effective microorganisms and evaluate their subsequent conversion into vermicompost using Eudrilus eugeniae. Objectives: The specific objectives were to: (1) pre-digest groundnut shells using a bacterial consortium, (2) assess the vermicomposting efficiency of two substrate mixtures viz., 50:50 and 60:40 ratios of pre-digested groundnut shells to cow dung, and (3) compare the physical, chemical, and biological characteristics of the resulting vermicompost with a control. Methodology: The experiment was conducted over a period of 35 days. Groundnut shells were pre-treated with a bacterial consortium and combined with cow dung in two proportions: 50:50 (2000 g each of pre-digested groundnut shells and cow dung) and 60:40 (2400 g pre-digested shells with 1600 g cow dung). Vermicomposting was performed using E. eugeniae, and the resulting compost was analyzed for key physical, chemical, and biological properties. Results: The 60:40 mixture resulted in greater vermicompost output and a higher number of cocoons and juvenile worms, indicating better reproductive performance. In contrast, the 50:50 mixture produced vermicompost with significantly higher concentrations of macro- and micronutrients, along with greater microbial activity. Conclusion: A 50:50 ratio of pre-digested groundnut shells and cow dung is optimal for producing nutrient-rich vermicompost using E. eugeniae, making it a suitable choice for sustainable organic waste management.
