The effect of vermicomposting duration to macronutrient element in vermicompost was investigated. Three different treatments were prepared with eight replicates for each treatment namely cow dung: kitchen waste in 30:70 ratios (T1), cow dung: coffee grounds in 30:70 ratio (T2), and cow dung: kitchen waste: coffee grounds in 30:35:35 ratios (T3). Vermicompost produced by Lumbricus rubellus were analyzed in week tenth and thirtieth. In conclusion, longer duration of vermicomposting will enhance the quality of vermicompost. This is shown by the percentage increase of macronutrient elements (N & P) and declining of C/N ratio.
