One <br>kilogram of local Thai earthworms, Pheretima peguana, were introduced into wastes of three different organicbased materials (either water hyacinth scraps, food wastes, or corncobs) in a vermibin chamber with a constant <br>ratio of rice bran and cow dung. Each organic waste was tested at a high, medium or low ratio by weight with <br>rice bran, and cow dung. These materials were vermicomposted for 45 days. Physico-chemical parameters and <br>phytotoxicity assessed by germination index of the compost were analyzed on the final day of composting. <br>Values of pH, electrical conductivity, moisture content, total nitrogen, phosphorus, potassium, organic carbon, <br>and C/N ratio and germination index were determined. The vermicompost from all ratios of water hyacinth <br>scraps and food wastes with rice bran and cow dung had acceptable nutrient levels (nitrogen, phosphorus, and <br>potassium) as specified by the Thai agricultural standards, National Committee on Agricultural Commodity <br>and Food Standards, Ministry of Agriculture and Cooperative. Results suggest that these organic wastes are <br>suitable for large scale vermicomposting to produce a nutrient-rich fertilizer for organic farming.</p> ER -
