Abstract : An experiment was carried out to study the influence of pre-harvest foliar application of calcium (0.06%), boron (0.02%) and sorbitol (2%) along with a control on pollination, fruit set, fruit drop, fruit growth parameters and yield of mango cv. ALPHONSO. The result revealed that maximum pollen viability (89.69%), germination (56.30%) and pollen tube growth (158.99 µm), fruit set at pea stage (0.66%), fruit retension (2.23%), fruit length (9.98 cm), breadth (7.86 cm), weight (268.29 g), fruit volume (258.24 cc), number of fruit per tree (166.00) and yield per tree (44.60 kg) and minimum fruit drop (97.77%) were obtained under the foliar spray of boric acid (0.02%).
