A field experiment was conducted at fruit research station, Imliya, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur to study the influence of GA3 and date of sowing on growth and development of custard apple seedlings. Significantly, maximum fresh weight of roots (0.75g), dry weight of root (0.20g) and total dry matter (0.37g) were obtained at 120 days after germination under 500ppm GA3 treatment. Minimum of these attributes was registered with untreated seeds. Among different sowing dates, D4 recorded maximum fresh weight of roots (0.87g), dry weight of roots (0.24g) and total dry matter (0.370g), while D1 recorded minimum of these attributes. However, When seeds were treated with 500ppm GA3 increased the height of the plants and maximum was recorded (4.24, 5.64, 9.79 and 12.86cm), girth of stem (1.20, 2.10, 2.93 and 4.68mm) and number of leaves per seedlings (4.18, 6.27, 9.42 and 13.86) at all stage of observations i.e. 30, 60, 90 and 120 days after sowing respectively. Whereas, treatment control gave minimum plant height, girth of stem and number of leaves per seedling at all the stage of observations. Interaction effect of GA3 and date of sowing was found significant and maximum fresh weight, dry weight, total dry matter, plant height, girth of stem and number of leaves per seedling was recorded with D4G3.
