Micronutrient availability as influenced by household waste based vermicompost application in calcareous soil of bihar during rice growth period

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.
