Abstract
Vermicompost is a good organic fertilizer preparing through interaction between earthworm and microorganism, which breakdown the nutrient substrate from organic waste. In this study we used eggshell powder and cow dung mixture for vermicompost. Eggshells were considered as solid bio waste in bakeries, hostel, food processing industries and households. It is rich in calcium carbonate and contains small amounts of protein. The experiment was carried out for 90days, the control and six treatments were maintained in eggshell powder and cow dung mixture was processed using the earthworm, Eudrius euginae. During the study period of growth and reproduction rates were recorded at the end of vermicomposting. Treatment T6 showed higher reproduction rate compared to other treatments. Physio-chemical parameters of the vermicompost such as pH, electrical conductivity, organic carbon, total nitrogen, phosphorous and potassium assessed were relatively good in all treatments compared to control. FESEM analysis showed the nutrient elements of vermicompost. Green gram (Vigna radiata), Black gram (Vigna mungo), and Fenugreek (Trigonella-foenium-graecum) seeds was germinated excellently when compared to control and were maintained in triplicates. We can conclude that, the eggshell powder showed good source of substrate for vermicompost, reproduction and survival of worm and also induce the growth of plants.
