Vermicompost has been emerging as an important source in supplementing and substituting
fertilizers in Agriculture. A number of individuals and institutions are taking interest in
production of vermicompost utilizing earthworm activity. The operational cost of production
vermicompost in a year works out to be 4.2 per kg on average, thus it is quite profitable to
the compost at Rs. 10/kg. As vermicompost can be produced in any non-economic place with
humidity, and cool temperature, it has a nil operational cost and provides a great scope for
extra income for the farm. Abandoned cattle shed or poultry shed or unused buildings can be
can also be produced in an open area, by providing low-cost thatched roof to protect the
Krishi Vigyan Kendra Tuniki identified a new intervention on the production of vermicompost
under mango orchard using galvanized welded mesh ring with the dimensions of 1.6 m diameter, 2
ft height, 5 m circumference, size of the mesh hole is 1inch with a capacity of 1-ton FYM/ring.
KVK Tuniki established this unit in KVK farm as there is no guarantee to get the income from the
mango orchard every year, due to alternate bearing, climatic conditions and fruit dropping due to
heavy winds, etc. Therefore the production of vermicompost can give additional/ subsidiary income to
the farmers and the land can be utilized effectively and also no need to apply extra nutrition to
mango trees as the excess water is drained into the root zone in the form of vermi wash.
The cost of production of vermicompost in one ring with the capacity of 1000 kg FYM and 35 % of
compost recovery is worked out and presented in the following table.
