introduction
Vermiculture is the culture of earthworms. The earth worms can be used in the
vermicomposting operation .Vermicomposting is the process by which worms are used to
convert organic materials into a fertilizer known as vermicompost.Since compostingand
vermicomposting are of the most promising low-cost technologies to convert municipal
organic contaminant solid wastes into valuable organic fertilizer (Misra et al.,
2003).There are many factors influencing the quality of produced compost, which include
the pre-processing, particle size and feedstock utilized, the C/N ratio, bio-accelerator,
nutrients, pH, aeration, moisture content, temperature, the maturation stage, etc (M.E. El-
Haddad et al., 2014).vermicompost soil is rich in bacterial and fungal species which can
degrade vast variety of organic waste into simpler soilnutrients(Bharat et al.,2015).The
worms feed on organic materials, and fragment and digest them in their gut by their own
enzymes and with the help of ingested micro-organisms, and excrete nutritionally rich
feces or casts.The earthworm casts have been shown to contain increased quantities of
important plant nutritional elements such as nitrogen, phosphorus and potassium together
with the biologically active substances stimulating plant growth (Lee 1985).It is the same
natural process that produces the dark humus layer on the forest floor. Modern
composting differs only in the application of scientific knowledge and technology to
promote morerapid decomposition and better control of the final product in an environmentally sensitive way.The present investigation is to study effect of
vermicompost preparation from municipal organic waste and to observe its effect on plant
growth and yield.
