Results showed a reduction in pH and total organic carbon and an increase in electrical conductivity, ash content, nitrogen, phosphorus, and potassium after vermicomposting. Carbon/nitrogen decrease followed: VU3 > VU1 > VU4 > VU2 > VU5, whereas a maximum reduction in carbon/phosphorus (60.7%) was observed in VU3 and a minimum (44.8%) in VU5. Seed germination assay of Cicer arietinum was 71�138% with maximum in VU3. Respiration rates of 69�115 mgCO2 kg?1VC48h?1 were achieved signifying stability and non-toxic impact. The presence of FV waste in vermi-units enhanced earthworm population, biomass, growth rate, and cocoons. VU3 exhibited higher macro- and micronutrients as well as worm growth and fecundity over other vermi-units. Based on results, FV waste and CD amendment at 25% and 50%, respectively, are suggested as appropriate to produce enriched vermicompost from BS using Eisenia fetida. � 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.en-USC/N ratioEisenia fetidaSeed germinationSoil respiration rateVermicompostingArticlehttps://link.springer.com/10.1007/s13399-022-03664-x
