Abstract : An experiment was conducted on 45-year-old mango cv. Dashehari trees in Lucknow, Uttar Pradesh. Pruning was done on December 1992, with 5 pruning severity levels (from first to fifth order pruning). The growth of emerging shoots on pruned branches was influenced by severity of pruning. Length and girth of emerging shoots were more in first, second and third order pruned trees than in fourth and fifth order treatments, whereas it was minimum in the control. Fruit yield was higher in fourth and fifth order pruned trees than the control. No fruit yield was obtained in first, and second order pruned trees during first and second year of fruiting, but yield was obtained in an increasing trend in subsequent years. Cumulative fruit yield of 6 years indicated that fourth order pruned trees gave the highest yield, whereas it was lowest in the control.
