Bioconversion of vermicomposted weed plants waste using eudrilus eugeniae kinberg for promoting the growth of brinjal (solanum melongena)

Present study deals with the bioconversion of vermicomposted weed plants waste using Eudrilus eugeniae Kinberg for promoting the growth of Brinjal (Solanum melongena) preparation of weed plants waste vermicompost and its physico chemical parameters were analyzed, enumeration of microorganisms bacteria, fungi and actinomyces from vermicompost, preparation of vermiwash and vermicompost extract and its physico chemical parameters were analyzed, growth parameters and biochemical characteristics also studied of Brinjal. The weed plants waste vermicompost was studied the physico chemical parameters like pH, temperature, electrical conductivity, organic carbon, total nitrogen, total phosphorous, total potassium and C:N (ratio) were studied. The number of colony forming unit of the vermicompost of Bacteria, Fungi and Actinomyces. After preparation of vermicompost, vermiwash and vermicompost extract was prepared using after 45 days worked healthy earthworm. The Physico chemical parameters of vermiwash and vermicompost extract also studied.  The growth parameters like seed germination, shoot length, root length, total fresh weight, total dry weight, leaf area index and vigour index were studied and biochemical characteristics such as chlorophyll a and b, total chlorophyll, carotenoide and anthocyanin were estimated.  Based on the results growth parameters and biochemical characteristics were higher in Brinjal treatments 5 and 6 using various concentration of vermicompost, vermiwash and vermicompost extract.
