Effect of gibberellic acid and NAA on growth, yield and quality of brinjal (Solanum melongena L.) in cv. Azad Kranti

Abstract

The present experiment entitled “Effect of Gibberellic Acid and NAA on Growth, Yield and Quality of Brinjal (Solanum melongena L.) in cv. Azad Kranti” was conducted at Agricultural Research Farm of Rama University, Mandhana, Kanpur (UP) in the year 2022-2023. The experiment was laid out into Randomized Complete Block Design (RCBD) with 3 replications and 9 treatments viz. T1 = 20 ppm NAA, T2 = 40 ppm NAA, T3 = 25 ppm GA3 T4 = 50 ppm GA3 T5 = 20 ppm NAA + 25 ppm GA3, T6 = 20 ppm NAA + 50 ppm GA3, T7 = 40 ppm NAA + 25 ppm GA3, T8 = 40 ppm NAA + 50 ppm GA3 and T9 = Control. The results of study revealed that maximum plant height (25.2, 39.2 and 69.0 cm at 30, 45, and 60 DAT respectively), number of leaves (19.8, 51.5 and 82.2 at 30, 45, and 60 DAT respectively), Number of branches (17.3), Number of fruits per plant (17.3), Fruit Length (10.0 cm) Fruit Diameter (15.7 cm), Fruit Weight per plant (2 kg), Fruit weight per plot (31.9 kg), Fruit yield per ha (31 t/ha), TSS (5.50 Brix), Vitamin C, (7.9 mg/100 gm) and Anthocyanin (6.2 mg/100 gm) and B:C ratio (1.2) was reported in T8 (40 ppm NAA + 50 ppm GA3) followed T7 = 40 ppm NAA + 25 ppm GA3. Whereas minimum values of growth, yield, quality and economics were noted in control.
