Abstract : An experiment was conducted at Nazirpur, West Bengal, India to study the effect of foliar application of zinc, iron and boron, each at 0.1, 0.2 or 0.4%, on 30-year-old mango cv. Fazli trees. All the micronutrients significantly influenced flowering, fruiting and fruit size. Plants treated with 0.4% Zn in combination with Fe and B at 0.1% produced the most fruits/tree (621) and the highest yield (462.1 kg/plant); corresponding figures for controls (no Zn, B or Fe applied) were 356 fruits and 230 kg/tree. The greatest fruit weight (839.3 g) and length (16.76 cm) were obtained with the highest level of 0.4% B combined with the medium level of Zn and Fe at 0.2%.
