Subject: Feedback about "Jaigopal" earthworm
Dear sir,
First of all, thank you for providing.us (IITG) "Jaigopal" Vermi culture technology. We have utilized this technology for production of good quality vermicompost at higher rate. Please
find the feedback from our investigation about the performance of
..Jaigopal,,
earthworm.
1)
Comparison of Jaigopal Earthworm (JG) over Esinea fetida (EF) and Eudrilus Euginea (EG)
o o . t
Reproduction rate of JG is very fast as compare to EF and EG.
Survival temperature ranges from 4 to 45oC. They are resistive to light rays. The degradation rate was very fast. Organic waste such as Vegetable waste, water hyacinth and industrial sludge were tested.
o
Waste can be feeded directly even without any pre-treatment or by adding any amendments such as cattle manure and dry leaves.
o o
Final product is of uniform size. Cocoon production is more as compared to other two species.
o
Final product was rich in NPK and pathogen free.
2) Onsite vermicomposting reactors
We have provided household vermireactors to some of the faculty members of IIT Guwahati. The details about the reactors and compost production are given below.
Reactor size:
w
Finding:
o o
Jaigopal species was tested for it efficiency in field trials.
Everyday's kitchen waste including vegetable waste, fruit peels, cooked food waste, egg shells and tea waste were added.
o
1.5 to 2.5 kg waste was added everyday to the reactor which was sectioned to--five
portions for the feeding.
First feeding was done on the first section followed by subsequent section for five days' Once the cycle is over, the feeding was repeated from the first section and so on. Five days were more than enough for the degradation of the waste materials for which the reactor was designed and harvesting was done after 25 to 30 days. a
Reproduction rate and the number of cocoon production were very much higher.
a
Quality of vermicompost was very good with rich NpK and free of pathogens.
After 30 days of vermicomposting: 15 kg of vermicompost was harvested
Thank you
With best regards
(Ajay Kalamdhad)
