Abstract: The experiment was aimed to investigate the effect of pruning intensities on custard apple growth and quality. The eight year old custard apple trees selected. The pruning was done at 30, 45, 60 and 75 days after leaf fall and on main shoot, subsequent secondary and tertiary shoots on whole plant from top to end with different intensities i.e. tip pruning, pruning at 30, 45, 60, 75, 90 cm and control. Among the treatments significantly maximum shoot length at last harvest (55.58 cm) was recorded in 90 cm pruning intensity at 45 days after leaf fall (D2P6). Among the treatments significantly maximum number of flowers shoot-1 (9.12), maximum fruit set (73.5 %), average number of fruits (98.27) and fruit yield (23.75 kg tree-1) were found in 30 cm pruning intensity at 45 days after leaf. Maximum fruit size at polar (10.04 cm) and equatorial diameter (10.32 cm), average weight of fruit (333.67 g) and minimum stony fruit per cent (7.72 %) were found in treatment combination D2P6. In case of quality contributing characters maximum pulp (55.68 %), minimum seed (6.34 %), and seed: pulp ratio (0.13) was found in treatment combination D2P6. As compared to other treatments higher TSS content (25.07 %) was recorded in in treatment combination D2P4.
