Vermicompost is dropping of earthworms after the intestinal digestion of organic matter; these dropping are high in nutritive value. Since vermicompost helps in enhancing the activity of micro organisms in soils which further enhance solubility of nutrients and their consequent availability to plants is known to be altered by micro-organisms by reducing soil pH at micro sites, chelating action of organic acids producing by them and intraphyl mobility in fungal filaments. Such inputs or Organic manure has number of apparent agronomic and environmental advantages. In recent years increasing fertilizer input cost, soil health, sustainability and pollution considerations have led to renewed interest in the use of organic manure. Vermicompost being a major component of organic manure has attracted attention of scientist worldwide, since it is an entirely natural product which maintain soil ecosystem and leaves no harmful effect on it. An analysis of Cost and return structure is highly essential in case of Production and marketing of any commodities, as it is the systematic way for estimating profitability. Against this backdrop, the present study has been made to analyze the cost and return structure of vermicompost production and marketing in Tirunelveli district.
