Response of micronutrients to B, Cu, Zn, Ma and Fe singly and in combination as formulation Micron C*, when applied as foliar spray to Tylophora indica clone TCl was studied for a period of two years. Boron 5 ppm significantly increased the herbage and number of leaves, whereas no significant increase with Cu, Zn, Mn, Fe and Micron C was noticed. However, both Cu and Zn were effective in increasing totaj alkaloid content in leaf. Micron C too was found to have stimulatory effect. No difference in major constituents in total alkaloid extract was found.
