Effect of different levels of gibberellic acid (GA₃) on growth and yield of two varieties of cucumber (Cucumis sativus L.) cv. Malini, Nazia F₁

The present investigation was carried out with title “Effect of different levels of gibberellic acid (GA₃) on growth and yield of two varieties of cucumber (Cucumis sativus L.) cv. Malini, Nazia F₁” atResearch Farm, Department of Horticulture, Naini Agricultural Institute, SHUATS, Naini, Prayagraj, Uttar Pradesh during the Zaid-2023-24 with a view to identify the effects of different combinations of PGR doses and its role in growth, yield and quality of two varieties of cucumber. The experiment was laid in Randomized block design with 10 treatments and 3 replications. Under this experiment, overall, 10 treatment was taken T₁ (Malini + Control), T₂ (Malini + (GA₃) @ 5 ppm), T₃ (Malini + (GA₃) @ 10 ppm), T₄ (Malini + (GA₃) @ 15 ppm), T₅ (Malini + (GA₃) @ 20 ppm), T₆ (Nazia F₁ + Control), T₇ (Nazia F₁ + (GA₃) @ 5 ppm) T₈ (Nazia F₁ + (GA₃) @ 10 ppm),T₉ (Nazia F₁ + (GA₃) @ 15 ppm) and T₁₀ (Nazia F₁ + (GA₃) @ 20 ppm). From the above experimental finding it may be concluded that the treatment T₁₀ (Nazia F₁ + (GA₃) was found to be best in the terms of growth, yield and quality of Cucumber. The highest net return was found in the T₁₀ (Nazia F₁ + (GA₃) with (Rs 1,76,507/ha) and the highest B:C ratio was found in the same with 2.39.
