Abstract:
A field experiment was carried out on bitter gourd during 2021 March to June in an open field, Central Research Farm, Department of Horticulture, from, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The experimental field was laid out in a randomized block design (RBD) with ten treatments of different concentrations of three kinds of Plant growth regulators, namely GA3, NAA and Cycocel CCC with just one variety replicated thrice. The variety used in this experiment was Kashi Mayuri (IIVR). The experiment comprised of nine foliar applications consisting of GA3 @ 40 ppm l-1, 60 ppm l-1, 80 ppm l-1,; NAA @ 100 ppm l-1, 150 ppm l-1, 200 ppm l-1; CCC @ 100 ppm l- 1, 200 ppm l-1, 300 ppm l-1 with control Experiment results revealed that Flowering parameters viz., days to male flower initiation (35.08) and female flower intiation (24.87) maximum was recorded by (NAA @ 100 ppm and 150 ppm).Whereas, Yield parameters viz. fruit weight (105.89 g), fruit length (16.30 cm), fruit diameter (7.60 cm), no. of fruits/plant (38.67), fruit yield/ hectare (35.25 t/ha) was recorded maximum in (GA3 @ 60 ppm l-1).
