Abstract:
An investigation was carried out on “Effect of time of spray and plant growth regulators on muskmelon (Cucumis melo L.)” at College Farm, College of Horticulture, S. D. Agricultural University, Jagudan, Gujarat, India during Summer 2021. The experiment was laid out in Factorial Randomized Block Design with eighteen treatment combinations involving three levels of time of spray i.e., t₁ (2 leaf stage), t₂ (4 leaf stage) and t₃ (2 and 4 leaf stage) and plant growth regulators in six levels i.e., p₁ (NAA @ 100 ppm), p₂ (NAA @ 150 ppm), p₃ (Ethrel @ 100 ppm), p₄ (Ethrel @ 150 ppm), p₅ (GA₃ @ 10 ppm) and p₆(GA₃ @ 20 ppm) in Gujarat Muskmelon 3 variety. T₁₈ (Spray at 2 and 4 leaf stage + GA₃@ 20 ppm) found superior on length of main vine (cm) at 60 DAS and at final harvest. Whereas T₁₆ (Spray at 2 and 4 leaf stage + Ethrel @ 150 ppm) produced superior results on number of primary branches at final harvest, number of days taken for first male flower, number of days taken for first female flower, number of male flowers per vine, number of female flowers per vine, sex ratio (male: female) and number of days taken from fruit set to edible maturity as compared to the other treatments.
