Effect of Plant Growth Regulator on Yield and Fruit Quality of Bitter Gourd (Momordica charantia L.)

The present experiment was conducted at Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during the session 2022 - 2024. The experiment was laid out in randomized block design (RBD) with three replications, and the study consists of thirteen treatment combinations including control. The treatment consisted of T0 Control, T1 - GA3 75ppm, T2 - GA3 100ppm, T3 - GA3 150ppm, T4 - GA3 200ppm, T5 - Ethrel 300 ppm, T6 - Ethrel 400 ppm, T7 - Ethrel 500 ppm, T8 - Ethrel 600 ppm, T9 - NAA 50 ppm, T10 - NAA 100 ppm, T11 - NAA 150 ppm, T12 - NAA 200 ppm. The best treatment was T12 (NAA200ppm) &T11 (NAA150 ppm) which shows highest values in all the parameters viz., node to which first female flower appears (18), node to which first male flower appears (11), and fruit shape, fruit color. Increased flowering, fruit yield and quality might be due to the increased absorption of nutrients when given as foliar application.
