Application of vermicompost is considered to be a good option to safe supply of micronutrients for crop production. Again, the quality of vermicompost varied with the earthworm species and their feeding materials used. A study was conducted to find out the variable roles of vermicomposts produced from various sources to meet the Zn and B requirement of cauliflower grown on a nutrient-deficient light-textured soil. Six treatment combinations including one control treatment and one treatment having 100% chemical sources of Zn-B (3 kg Zn ha -1 ? 2 kg B ha -1 ) were tested.
