The present investigation entitled “Response of micronutrients and GA₃ foliar feeding on flowering and fruiting behaviour of Ber (Zizyphus mauritiana Lamk.) fruit cv. Banarasi Karaka” 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 flowering and fruiting behaviour of ber. The experiment comprised of two foliar applications during September and November with five treatments on the cultivar Banarasi karaka with four replication. The data was recorded and analysed by using Randomised block design. Under the investigation, ber plants were studied for the parameter of days taken to flowering initiation, days taken to 50% flowering, fruit set, fruit retention. The minimum (6.75) days taken to flowering initiation and the minimum (25.75) days taken to 50% flowering, the maximum (12.69%) fruit set and maximum (19.75%) fruit retention 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
