Kale (1998) reported that vermicompost prepared from wastage of agriculture and industries contained different nutrient with organic carbon 9.15 to 17.98 per cent, total nitrogen 0.5 to 1.5 per cent, available phosphorous , 1.0 to 3.0 per cent, copper 2.0 to 9.5 ppm and iron 2.0 to 2.3 ppm.
Reddy and Reddy (1998) recorded 1.98 % N, 1.23 % P and 1.59 % K,132 mgKg-1 of total Zn, 70.05 mg Kg -1 of Cu, 1440.2 mg Kg -1 of Fe and 317.5 0mg Kg -1 of Mn in vermicompost produced from wastage.
Effect of vermicompost on soil:
The application of vermicast on depleted soil rejuvenates its fertility enriches soil with different nutrients, maintains its quality and plays important role in conserving biological and water resources.( Chaoui et al, 2003, Arancon et al,2006).
Earthworm for vermicomposting ingests microorganism and organic residues fragmented by gizzard which act as nutrient source for them. (Edwards and Bohlen, 1996), in the process of ingestion to production of cast the gut of earthworm secretes effective enzymes and mucus that is helpful in selective stimulation of microbial species which are beneficial in agriculture point of view. (Doube and Brown, 1998). The better and further microbial activity in the fecal material or cast of earthworm makes it better and fragmented than the matter that the earthworm has consumed. (Edwards, 1995). Earthworm has unique characterstics of inoculating soil with fine peat like ground organic residuals and microorganism which effectively contribute in soil flora and fauna with advancement in decomposition rate and later helps in ingesting the microorganisms by the earthworms.
The castings that are produced by earthworm are neutral in pH, and maintains the pH level of soil to neutrality, they are we...

...storical time the seeds are soaked and plants are drenched with compost liquid extract for the purpose of fertilizing the crop and suppression of plant disease. (Rodale, 1967). Different experiments conducted had shown that compost tea has significantly increased plant health status, yield along with its nutritional quality. (Elad and Shtienberg, 1994; Al-Dahmani et al., 2003; Scheuerell and Mahaffee, 2004; Welke, 2005; Edwards et al., 2006). Compost teas, the water based extract use has been increasing to meet the nutrient requirement of the crop and as the consequences compost tea industries are increasing too. (Carpenter-Boggs, 2005).
Vermicompost has been found effective to suppress the plant disease and the expected mechanism by which Vermicompost suppress the plant disease are induced resistance, antibiosis and competition. (Scheuerell and Mahaffee, 2002).
