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 quality attributes of mango cv. Amrapali” conducted in 2023. The experimental material for the present investigation was comprised of 9 treatments with KNO₃ @ 1.0%, 2.0% and GA₃ @ 25 ppm, 50 ppm along with their combinations and water spray as control. The impact of various treatments on different quality attributes viz., TSS (⁰Brix), ascorbic acid (mg/100 g), acidity (%), total sugar (%), reducing sugar and non-reducing sugar was recorded. The data revealed a significant influence, with the maximum TSS (21.81 ⁰Brix), ascorbic acid (52.50 mg/100 g), total sugars (18.63%), reducing sugars (6.99%), non-reducing sugars (10.29%) and the minimum acidity (0.15%) was recorded in treatment T₈ (foliar spray of KNO₃ @ 2% + GA₃ @ 50 ppm) which is at par with T₇ (KNO₃ @ 1% + GA₃ @ 50 ppm). However, the treatment T₉ (control) recorded less performance for the similar characteristics except for acidity content.
