An experiment was conducted at Horticulture Research Field, Department of Horticulture, Naini Agricultural Institute, Faculty of Agriculture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, during February-May, 2023 on cucumber. The experiment was laid out in factorial randomized block design with twenty treatment combinations and was replicated thrice. The experiment consisted of two factors. Factor H: Hybrids (TMCU-1107, TMCU-1125, TMCU-3112 and Saira-934) and Factor T: Different concentrations of GA₃+ZnSO₄ (T0 - Control (water spray), T₁ -GA₃ @100ppm+ZnSO₄ @0.25%, T₂ - GA₃ @200ppm+ ZnSO₄ @0.50%, T₃ - GA₃ @300ppm+ ZnSO₄ @0.75% and T₄ - GA₃ @400ppm+ZnSO₄ @1%). TMCU-1125 recorded significantly higher yield attributes of cucumber over other hybrids in parameters like vine length at 80 DAS (102.6 cm), days to 50% flowering (40), days to 1^st harvest (46), number of fruits per plant (11), fruit length (18.4 cm), average fruit weight (237.5 g), average fruit yield per plant (2.6 kg) and ascorbic acid content (0.8 mg/100g). Among different treatments, GA₃ @300ppm+ ZnSO₄ @0.75% resulted in significantly longer vine at 80 DAS (98.4 cm), Days to 50% flowering (43), days to 1^st harvest (50), number of fruits per plant (9), fruit length (16.6 cm), average fruit weight (232.0 g), average fruit yield per plant (2.0 kg) and ascorbic acid content (0.5 mg/100g). The interaction effect of T8 (TMCU-1125 + GA₃ @300ppm+ ZnSO₄ @0.75% is best suited for getting higher growth, yield, quality of cucumber.
