Abstract : An experiment was conducted to study the effect of ortho-phosphoric acid (H3PO4), potassium di hydrogen phosphate (KH2PO4), dipotassium hydrogen phosphate (K2HPO4), calcium nitrate {Ca(NO3)2} and salicylic acid (SA) on induction of flowering, sex ratio, fruit set, retention of fruits and fruit quality in mango cv. Baneshan at commercial orchard located at Hyderabad. The chemicals significantly influenced the flowering and fruiting characters. The percentage of new laterals which flowered was highest with H3PO4 0.5 per cent and K2HPO4 1.0 per cent spray. Panicle emergence was earliest in SA 100 ppm spray. The percentage of hermaphrodite flowers was highest with K2HPO4 1.0 per cent spray. The fruit bearing was highest with KH2PO4 1.0 per cent. Highest fruit yield was recorded in trees treated with H3PO4 0.5 per cent or K2HPO4 1.0 per cent spray. Average fruit weight was highest in trees treated with K2HPO4 1.0 per cent spray where as titrable acidity was highest in KH2PO4 1.0 per cent and SA 200 ppm sprays.
