Abstract:
The investigation titled "Effect of growth retardants on dwarfism and flowering of papaya (Carica papaya L.) cv. GJP 1" was conducted at the Fruit Research Station, Lalbaug, Junagadh Agricultural University, Junagadh during the year 2022-23. The experiment followed a Randomized Block Design with three replications and included 10 treatments: T₁ (Control), T₂ (Ethrel 150 ppm), T₃ (Ethrel 250 ppm), T₄ (Ethrel 350 ppm), T₅ (Cycocel 750 ppm), T₆ (Cycocel 1500 ppm), T₇ (Cycocel 3000 ppm), T₈ (Paclobutrazol 250 ppm), T₉ (Paclobutrazol 500 ppm), and T₁₀ (Paclobutrazol 1000 ppm). The results of the study showed that the treatment with Cycocel 3000 ppm resulted in the smallest plant height (142.44 cm), shortest average internodal length (2.87 cm), lowest bearing height (63.97 cm), height of the plant at the time of bearing (105.90 cm), leaf stalk length (46.51 cm), and shortest time to first flowering (61.83 days) and first fruit set (66.61 days). Additionally, this treatment exhibited a male-to-female ratio (plant) of 0.89 and the highest number of leaves (33.74).
