Abstract : An experiment was conducted in Hyderabad, Andhra Pradesh, India, during 2000/01 to study the effects of KNO3, Ca(NO3)2, NH4NO3 and KH2PO4 (each at 1 and 2%) foliar spray on the flowering and fruiting of pruned 8-year-old mango (cv. Baneshan) trees. Data were recorded for days to flowering, days to panicle emergence, length, percentage of hermaphrodite flowers, number of fruits per panicle, number of fruits per tree, yield per tree, fruit weight, total soluble solids content and titratable acidity. The chemicals induced 100% flowering on one and 2 flushes, while flowering was 70% in shoots with 3 flushes and no constant results were obtained on shoots with 4 flushes. There was no significant change in fruit quality. KH2PO4 and KNO3 produced more fruits per tree compared to the control.
