Abstract: Demand of eco-friendly environment, sustainable agriculture and economy brought recycling of organic wastes into enriched nutrient supplement for soil as well as plant. High amount of starch, proteins contained potato peel (PP) waste can be degraded by activity of earthworm to enrich the nitrogen content of manure by vermicomposting. A small scale experimental study report on growth activity of earthworm that is Eudrillus euginaea was conducted in different proportion of potato peel in Centurion University and Technology Management, Bhubaneswar, Odisha, India. Earthworms respire through their skin, so they are highly reactive to any change in their environment. Earthworms act in the soil as aerators, grinders, crushers, chemical degraders and biological stimulators. They secrete enzymes, proteases, lipases, amylases, celluloses and chitinases which bring about rapid biochemical conversion of cellulosic and the proteinaceous materials in the variety of organic wastes which is originate from homes, gardens, farms, industries and other food production factories. As organic waste, Potato is being largely used as different products like French fries, potato chips, potato starch, potato powder and potato protein etc. During the processing operations reasonable amount of potato solids remove as waste especially the potato peel, which may be a good source of bioactive compounds. In this experimental study different proportion of potato peel that is 0, 20, 40, 60, 80 and 100 percentage is used to know the growth and other reaction activity of earthworm Eudrillus euginaea during the process vermicomposting. The growth rate and other parameter like moisture, pH, temperature and electrical conductivity was being measured in time interval to known the reason of growth and death of earthworm.
