A pot experiment was conducted during Kharif 2018 at RPCAU, Pusa to find out the effect of vermicompost prepared from household waste and cow dung (1:1, w/w) onDTPA extractable micronutrients: Iron (Fe), Copper (Cu), Zinc (Zn) and Manganese (Mn)status in soil during rice crop growth. There were four levels of vermicompost along with three levels of chemical fertilizers. Results indicated that an increasing trend was observed in DTPA extractable micronutrients in soil from transplanting to tillering stage whereas a gradual decline was observed in post-harvest soil. However, in post-harvest soil content of available micronutrients was low as compared to tillering stage but was greater than initial soil micronutrients content for all the treatment combinations except control which indicates a significant build-up of available micro-nutrients in post-harvest soil of rice on application of graded dose of vermicompost alone or in combination with different dose of fertilizer. The extent of build-up was higher under higher dose of vermicompost and fertilizer. Treatment involving application of vermicompost (2.5t ha-1) along with full dose of fertilizer (RDF) emerged out as best treatment combination with respect to micronutrient nutrient availability.
