Abstract: Custard apple requires more corrective pruning. Initially, it is essential to develop a good growth and better yield over a long period of time. A trail was conducted to standardize the pruning level and GA3 spray on morpho-physiological and yield in custard apple cv. Arka Sahan. The maximum plant spread (E-W and N-S) was observed with (T1) control treatment and followed by 25% canopy removal, the minimum was obtained in 75% canopy removal treatment and followed by 50% canopy removal. The highest leaf area and leaf area index was recorded in 75% canopy removal treatment and followed by 50% canopy removal. The highest number of fruits (108.35) in control treatment and followed by (T5) 25% of canopy removal + 1500 ppm GA3 (70.27) and (T2) 25% canopy removal treatment (69.44). The fruit yield was observed in (T1) control treatment (25.51 kg/plant or 10.20 t/ha) and it was followed by the (T5) 25% of canopy removal + 1500 ppm GA3 (18.66 kg/plant or 7.46 t/ha) and (T6) 25% of canopy removal + 2000 ppm GA3 treatment (18.36 kg/plant or 7.34 t/ha).
