Abstract
The organic bio-fertilizers produced by using earthworms may replace inorganic fertilizers and their use can increase yield and quality of agriculture products, which is required nowadays. Eisenia fetida (red worm) is the most prominent species of earthworms used for the production of vermicompost so this species can be used for organic waste management. During the present investigation, vermicompost samples prepared from different organic wastes are cow dung, cow dung + congress grass, (Parthenium hysterophorus), cow dung + kitchen waste and cow dung + mixture of different weeds (Parthenium hysterophorus, Lantana camara and chenopodium album). The changes in the micronutrients like C:N ratio, potassium, phosphorus, nitrogen and carbon were observed with a time interval of 0, 30, 60, and 90 days and it was observed that nitrogen, potassium, and phosphorous contents in each samples of vermicompost under investigation increased but found maximum in the kitchen waste.
