A field experiment was conducted during the winter season of 2024-2025 at the Crop Research Farm, School of Agricultural Sciences, Jaipur National University, Jaipur (Rajasthan), to investigate the effect of plant growth regulators and varieties on vegetative performance. The study utilized a factorial randomized block design with three varieties (White Prosperity, Novlux and Oscar) and four levels of GA₃ (Control, 100 ppm, 200 ppm, 300 ppm), comprising 12 treatment combinations with three replications each. Results revealed significant variation among treatments for all measured parameters. Days to sprouting ranged from 10.46 to 12.93, with the minimum (10.46 days) recorded by the combined application of GA3 at 300ppm and variety Oscar. The highest plant height (87.20 cm), number of leaves per plant (9.66), leaf length (46.64cm), leaf width (2.73cm), and main stem diameter (1.72cm) were all achieved with the same combination. These findings indicate that the interaction of GA3 at 300ppm with the Oscar variety consistently enhanced early sprouting and superior vegetative growth compared to other combinations, making it a promising strategy for optimizing crop performance under similar agro-climatic conditions.
