Effect of Coir Pith Industry Waste Vermicompost Prepared Using Eisenia fetida on Growth of Vegetable Crop of Radish (Raphanus sativus)

Abstract

Present study deals with the effect of coirpith industry waste vermicompost using Eisenia fetida for promoting the growth of Radish (Rhapanus sativus) preparation of coirpith waste vermicompost and its physic-chemical parameters were analyzed, enumeration of microorganisms bacteria, fungi and actinomycetes from vermicompost, preparation of vermiwash and vermicompost extract and its physic-chemical parameters were analyzed, growth parameters and biochemical characteristics also studied of Radish. The coirpith industry waste vermicompost was studied the physic-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 units of the vermicompost of bacteria, fungi and actinomycetes were also assessed. After preparation of vermicompost, vermiwash and vermicompost extract was prepared using after 45 days worked healthy earthworm. The physic-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, and vigour index were studied and biochemical characteristics such as chlorophyll a & b, total chlorophyll, carotenoide and anthocyanin were estimated. Based on the results growth parameters and biochemical characteristics were higher in Radish treatments 5 and 6 using various concentration of vermicompost, vermiwash and vermicompost extract.
