osting on the growth of bok choy. The vermicomposting was carried out for 40 days. The total N content in vermicompost and soil was analyzed using the Kjeldahl method and the total N content in plant tissue using the wet destruction method with concentrated sulfuric acid and peroxide acid. The results showed that the combination of tofu dregs and cow dung significantly affected pH, DHL, water content, organic C, total N, available N, and C/N ratio of the vermicompost. Meanwhile, the number of earthworms significantly affected DHL, organic C, total N, available N, and C/N ratio. The effect of vermicompost application on the soil chemical properties was only seen on the total N, while on the plant growth parameters was seen on the number of leaves, fresh weight, dry weight and N uptake of plants. The combination of organic matter sources and the number of earthworms, based on the chemical properties of vermicompost and their effect on the soil chemical properties and plant growth parameters, showed that the treatment of P5C2 (100% cow dung and 10 earthworms) was the best combination in producing the highest content of vermicompost N a |
