Vermicomposting is an eco-friendly solution to the worldwide impacting problem of solid waste management. The present study involves the assessment of use of vegetable waste and corrugated cardboard waste as raw material and their evaluation in the growth of Catharanthus roseus and Tagetes erecta plants. Several variables including moisture content, pH, dry weight, calcium, magnesium and phosphates were assessed at regular intervals to get information about the nutrient qualities. The results showed an increases in the moisture content over the time due to active performance of earthworms. The pH content also shifts towards acidity or neutrality indicating the formation of organic acids and healthy microbial activity. The dry matter showed a steady decrease suggesting efficient microbial activity in breaking the organic materials and providing essential nutrients readily available for plant uptake. An increase in the content of macronutrients including calcium, magnesium and phosphates was also found during the process. The analysis of plant growth using the two types of vermicompost depicts that the vegetable waste produces nutrient-rich compost that greatly promotes the plant development and the corrugated cardboard decomposes more slowly but enhaces soil structure and moisture retention due to its high carbon content. The significance of this result was also supported from the results of ANOVA analysis.
