Kuliana lime is an outstanding Odisha cultivar with significant potential to be included in future crop improvement operations due to its flavor and juice content. This research was conducted at the Horticultural Research Station, Department of Fruit Science and Horticultural Technology, Orissa University of Agriculture and Technology, Bhubaneswar during 2019–2020 and 2020–2021 to determine the optimal growth regulator in terms of quality metrics. certain growth regulators 2,4-D (2,4-D @ 10 ppm and 20 ppm) and GA3 (GA3 @ 50 ppm and 100 ppm) and NAA (NAA @ 100 ppm and 200 ppm) and SA (SA @ 100 ppm and 200 ppm) and SPMD (SPMD @ 0.01 ppm and 0.5 ppm) and PUT (PUT @ 0.01 ppm and 0.5 ppm) and BR (BR @ 0.1 ppm and 0.5 ppm) quality of Acid Lime kuliana local. The biometrical observations on various quality features were recorded in the same seasons over 2 years. The best was for fruit quality, which has been determined on the basis of growth regulators performances, as growth regulator variation has a significant effect on the quality of fruit. Brassinosteroids showed the best effects for TSS (7.17 oBrix), acidity (6.05 %), total sugar content (0.61 %), reducing sugar content (0.41 %), ascorbic acid (36.35 mg per 100 mL of juice), chlorophyll content (33.03 mg/100 g), flavonoid content (119.91 mg/100 g), protein (0.82 mg/100 g) and carbohydrate content (10.29 mg/100g) with the other treatments, including the untreated fruits in both years of the study. Our results revealed that the BR gave superior results in quality attributes for Kuliana lime in the East and Southeast Coastal Plain Zones of Odisha.
