The present investigation was conducted during 2011-12 at Fruit research station, Sangareddy to study the influence of flower enhancing plant growth regulators and fruit set improving chemicals on mango cv. Banganpalli. Trees applied with paclobutrazol (3ml.m-1 of canopy diameter) alone significantly increases percent flowering (25% over control), panicle length and breadth at the time off full bloom stage. Significantly the highest fruits per panicle and yield were recorded in paclobutrazol (42.17% over control) alone applied trees compare to control. Boron (1.25gr.l-1) could able to significantly increase the fruit per panicle and final retention of fruits and increased the fruit weight reflecting in the overall increase in yield by 37 percent. Among the combination, maximum increase in yield over control was recorded in paclobutrazol application along with spermidine at 0.01mM (63.11 %), NAA at 80 ppm + spermidine at 0.01mM (57.59 %), NAA at 80 ppm + boron at 1.25gr.l-1 (60.03 %). However, based on benefit cost ratio spraying of NAA + Boron has give maximum benefit cost ratio of 3.06. Among the fruit set improving chemical boron either alone or in combination with NAA has recorded highest improvement in the yield.
