Pruning and use of paclobutrazol (PBZ) have been identified as common strategies for enhanced flowering and productivity enhancement in mango. The present study was aimed to investigate the effects of pruning (current and previous seasons vegetative growth) and PBZ (3 ml/ m canopy diameter) on flowering, yield and leaf phenol contents in mango cvs. Raspuri. Early flowering as a result of PBZ application led to advanced fruit harvest by 20.4 days in trees pruned to current seasons growth followed by 20.7 days in unpruned trees. Drastic increase in total phenolics, total flavonoids and phenolic acid contents were observed at 75 days after PBZ application in PBZ treated unpruned trees and in trees pruned to current seasons growth. The high levels of coumaric acid, 4-hydroxy benzoic acid and salysilic acid and low levels of caffeic acid and t-cinnamic acid were observed following PBZ application in tree pruned to current seasons growth and unpruned trees compared to control. Studies indicated that, the pruning of trees to current seasons growth and PBZ application can influence the phenols and flavonoids contents of mango
