Enriched Vermicompost Made through Bio Waste of Soybean Stover (Dry Matter) and Fresh Cow Dung Using Earthworms (Eisenia fetida spp.)

This investigation was associated with different materials and techniques on bio-fertilizer application in soybean stover (dry matter) and fresh Cow dung for effect of bio fertilizer and earthworms (Eisenia fetida sp.) on bio waste decomposition. This study was analyzed by RBD (Randomized Block Design) with 6 treatments have to bio fertilizers combination i.e. (E1-control, E2- Rhizobium, E3- Rhizobium+ PSB, E4-Rhizobium+ KSB, E5-Rhizobium+ PSB+KSB, and E6-Rhizobium+ PSB+ KSB+ Trichoderma) and earthworms with 4 replications. The research was conducted at MRPC in Department of Soil Science and Agricultural Chemistry, JNKVV, Jabalpur during the Rabi season of 2021-22 and 2022-23. The result interpreted by partial decomposition, duration of completion, conversion rate and recovery percentage of vermicomposting. The result revealed that partial decomposition (kg) found in enriched vermicompost higher to lower sequence i.e. E5 (7.11 kg)> E3 (7.18 kg) > E2 (7.19 kg) > E4 (7.20 kg) = E6 (7.20 kg) > E1 (7.28 kg) from initial weight (10 kg). The production of enriched vermicompost maximum found in E6 (5.58, 5.63 and 5.61 kg pot-1) within respective duration (42, 40 and 41 days) of vermicomposting in sequent years and statically pooled analysis. Conversion rate and recovery percentage of enriched vermicompost were increase with the combination of bio-agents. This investigation useful to making vermicompost using of agricultural waste through bio-fertilizer.
