Biocomposting of extracted peppermint plant residue (Mentha piperita) using red worm, Eisenia fetida and its effect on the growth of Vigna mungo (Urad)

The study on biocomposting of extracted peppermint plant residue, Mentha piperita using red worms, Eisenia fetida on the growth of Vigna mungo (Urad) showed that the worms transformed 1:3 waste: dung medium into bio-compost one week earlier from 1:1 and two weeks earlier from 3:1 media. Rate of reproduction of worms was recorded 2.5 times faster in 1:3 medium than that of 3:1 and the number of earthworms was counted 2.09 times more in 1:3 waste: dung medium than that of 3:1. It was noticed that the bio-compost transformed from 1:3waste: dung medium when mixed with soil in 1:3 ratio and used as growing medium, showed the maximum shoot length of V. mungo (28.2 cm) and the minimum (24.3 cm) when it was transformed from 3:1 (waste: dung) medium and used in 1:1 ratio of vermicompost and soil. Results were discussed in the light of known data
