Abstract:
The bottle gourd [Lagenaria siceraria (Mol.) Standl.] cv. was the subject of a field study at the Department of Horticulture experimental unit at the Tilak Dhari Post Graduate College in Jaunpur, Uttar Pradesh, in the Zaid season of 2021–2022 to investigate the Response of plant growth regulators on Growth and Yield attributes Kashi Ganga. The experiment was set up using a Randomized Block Design (RBD), with just one variety repeated three times, and ten treatments of various concentrations of the plant growth regulators NAA, Ethrel, and GA₃. Kashi Ganga was the variety utilised in this research. (IIVR). Nine foliar applications totalling T₂: NAA 150 ppm, T₃: NAA 200 ppm, T₄: NAA 250 ppm, T₅: Ethrel 50 ppm, T₆: Ethrel 100 ppm, T₇: Ethrel 150 ppm, T₈: GA₃ 50 ppm, T₉: GA₃ 100 ppm, and T₁₀: GA₃ 150 ppm with T₁: Control made up this trial. The findings indicate a significant impact of the interactions between various PGRs and spraying stages. With NAA 250 ppm, the maximum vine dimensions (404.64 cm), vine diameter (21.20 mm), internodal length (23.73 cm), number of nodes on the main vine axis (24.53), leaf area (261.83 cm²), number of primary branches (14.27 cm), number of secondary branches (6.15), Node at which first female flower appeared (6.30), days required for appearance of first female flower appeared (49.12) days required for first picking (54.59), maximum sex ratio (6.58/1), Maximum length of fruit (32.52 cm). Maximum fruit diameter (67.27 mm), maximum Number of fruit per vine (7.45), maximum weight of fruit (846.53 g), fruit yield per vine (6.31 kg), Maximum fruit yield per hectare (631.00 q/ha) was observed in treatment T₇ Ethrel 150 ppm and maximum number of male flower was observed in treatments T₁₀ GA₃ 150 ppm.
