Abstract: A field experiment was conducted to assess the effect of different chemicals, soil application of paclobutrazol and combined application of paclobutrazol with chemicals as foliar spray on flowering physiology and yield in mango cv. Imam Pasand at Department of Fruit Crops, Horticultural College and Research Institute, Periyakulam during the period between 2011 and 2012. The experiment was laid out with sixteen treatments and two replication in a Randomized Block Design. The soil application of paclobutrazol @ 0.75.a.i. m-2 of tree canopy diameter during September month along with foliar spray of KNO3 @ 1 percent twice during October and November at 20 days interval was very effective in suppressing the tree height (2.69 m), canopy spread (5.10 m N - S, 4.17 m E - W), shoot length (9.37 cm), inter nodal length (2.07 cm). In both the treatments viz., foliar spray of KNO3 combined with soil application of paclobutrazol @ 0.75.a.i. m-2 of tree canopy diameter and application of paclobutrazol alone were recorded the highest yield characters viz., panicle length (34 cm & 33.63 cm), hermaphrodite flowers (12.62% and 12.58%) and fruit yield (33.50 kg tree-1 and 31.40 kg tree-1) respectively are on par and statistically significant.
