Effect of Plant Growth Regulators on Growth, Yield and Quality Attributes of Brinjal (Solanum melongena L.) cv. Kalptaru

The present investigation was carried out at Agricultural Research Farm, School of Agriculture, Suresh Gyan Vihar University, Jaipur (Rajasthan) to study the Effect of plant growth regulators on growth, yield and quality attributes of Brinjal (Solanum melongena L.) cv. Kalptaru during kharif season of the year 2023-24. The experiment was laid down in RBD which consisted 10 treatment combinations viz; T1- Control (Water Spray), T2- NAA (25 PPM), T3- NAA (50 PPM), T4- NAA (100 PPM), T5- GA3 (50 PPM), T6- GA3 (100 PPM), T7- GA3 (200 PPM), T8- 2, 4-D (2 PPM), T9- 2, 4-D (4 PPM), T10-2, 4-D (6 PPM) and treatments were replicated three times. The results showed that treatment T6 (GA3 at 100 PPM) had a significant positive impact on various vegetative growth and quality parameters, while treatment T5 (GA3 at 50 PPM) significantly enhanced yield parameters. Additionally, the highest benefit-cost ratio (2.84) was observed with treatment T5, whereas the lowest benefit-cost ratio (1.21) was recorded in the control (T1).
