The present investigation was conducted on twenty-nine-year-old ber plants grown in sodic soil condition at Main Experimental Station, Department of Fruit Science, Acharya Narendra Deva University of Agriculture & Technology Kumarganj Ayodhya (U.P) during the year 2022-23 and 2023-24 to investigate the response of foliar application of micronutrients and GA3 on yield attributes of ber. The experiment comprised of two foliar applications during September and November with five treatments on the cultivar Banarasi karakawith four replication. The data was recorded and analysed by using Randomised block design. Under the investigation, ber plants were studied for the parameter of fruit weight, fruit length, fruit width, fruit specific gravity, yield. The maximum fruit weight (21.68 g), fruit length (4.48 cm), fruit width (3.48 cm), fruit specific gravity (0.982), yield (16.81 t/ha) was recorded in plants sprayed with ZnSO4 0.5% + Borax 0.5% + GA3 10 ppm, which was significantly superior over all other treatments. It was followed by T3 (Borax 0.5%), T2 (ZnSO4 0.5%) and T4 (GA3 10 ppm) treatments. The maximum fruit weight (15.86 g), fruit length (3.63 cm), fruit width (2.40 cm), fruit specific gravity (0.973), yield (12.69 t/ha) was recorded in control.
