ABSTRACT
An experiment on the effect of flower enhancing chemicals (Ca (NO3)2 (1%), KH2PO4 (1%) and H3PO4 (0.5%)) and fruit set improving chemicals (Spermidine @ 0.01mM, spermine @0.1mM and boron-20% @ 1.25gm.l-1) on percent flowering, fruit set and yield of mango. KH2PO4 and H3PO4 alone or in combinations with fruit set improving chemical significantlyincrease in percent of flowering, panicle length and breadth when compare to control trees. Significantly the highest fruits.panicle-1, yield and fruit.tree-1 (16.7 % over control) and was recorded in Ca (NO3) 2 applied trees and spermidine (22.9 % over control) applied trees alone compare to control.Spermidine alone could able to significantly increase the fruit.panicle-1 and final retention of fruits and increased the fruit weight reflecting in the overall increase in yield by 48.72 %. Among the combination, maximum increase in yield over control was recorded in Ca (NO3)2 + spermidine (87.27 %), H3PO4 + spermine (76.09 %), KH2PO4 + Spermine (74.51 %). However, based on benefit cost ratio spraying of Ca (NO3)2 + spermidine has give maximum benefit cost ratio of 3.35.
Key word: Flower enhancing chemicals, Fruit set improving chemical, per cent flowering, Polyamines, Mango.
