Abstract : An experiment was conducted on cv. Fazli at Mathurapur, West Bengal, India. Foliar applications of Zn (0.1, 0.2 and 0.4%, as zinc sulfate), Fe (0.1, 0,2 and 0.4%, as ferrous sulfate) and B (0.1, 0.2 and 0.4%, as borax) were made to 6-year-old plants in July and October. Both Zn and B promoted vegetative growth as indicated by plant height, trunk girth and spread of the young plants. The effect of Fe was less pronounced than those of B and Zn. Treatments with the micronutrients, however, was not very effective in increasing percentage flowering shoots in young mango plants, except in case of Zn at 0.2%. None of the treatments resulted in any significant variation in fruit number and yield. The highest individual fruit weight was recorded with the highest level of Zn.
