    • Abstract

       

      Micronutrients were sprayed singly and in combinations, at pre-bloom stage, onCatharanthus roseus plants grown in the field for 15 weeks. In general, all the nutritional regimes enhanced the growth of the plants. The growth responses of B, Zn + B, Fe + Cu + Zn + B were statistically significant. Maximum increases in the total alkaloid content of leaves, stems and roots were observed under Fe + B, Fe + Zn + Cu + B and Zn treatments respectively while few other treatments also caused considerable increase in the total alkaloid contents.
