An investigation was carried-out at new nursery, Adhartal, Department of Horticulture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur to evaluate the positive effect of foliar sprays of Potassium Nitrate (KNO3) and Gibberellic Acid (GA3) on fruit retention and yield of mango cv. Amrapali” conducted in 2023. The experimental material for the present investigation was comprised of 9 treatments withKNO3 @ 1.0%, 2.0% and GA3 @25 ppm, 50 ppm along with their combinations and water spray as control. The data obtained from a set of observations for each character were subjected to “Analysis of Variance” in Randomized Block design with three replications. The impact of various treatments on fruiting parameters, including the number of fruits, fruit weight, diameter, fruit length, pulp weight, pulp percentage, and yield per plant, was documented. The experimental results revealed that among the 9 treatments foliar spray of KNO3 @2%+ GA3@ 50ppm (T8) showed best performance on fruit retention (17.53%) and yield (44.10 Kg) of mango cv. Amrapali” and the control recorded less performance for the similar characteristics.
