Vermicompost are produced by the breakdown of organic waste which results in rich microbial diversity and it has many nutrients that support the plant growth. Vemicomposting is increasingly popular in diverse aspects including recycling of organic waste, efficient nutrient supplier for plant growth. The present study was conducted to investigate the effect of different substrates such as kitchen waste, coir pith and rice straw on the production of vermicompost. These vermicompost were assessed for nutrient values and subjected to studies on the growth of Vinca rosea. The temperature of the composting material ranges from 22° C to 35°C,pH was between 5.5 -9 , moisture content of the composting was recorded as 40% - 56%.The nutrient analysis reported that high amount of Total Organic Carbon(TOC) is in coir pith vermicompost i.e about 0.43% -0.63% ,The total phosphorus and available phosphorus are high in rice straw compost about 0.065 and 0.55% on the 75th day. The total kjedhal nitrogen was about 1.42% in the kitchen waste obtained on the 45th day. The result indicated that vermicompost is a good biofertilizer and showed better growth patterns in Vinca rosea cultivated by the vermicompost prepared using coir pith.
