A field experiment was carried out during the months of March to November, 2019-2020 at Horticulture Research Farm, Department of Horticulture, Naini Agriculture Institute, Sam Higginbottom University of Agriculture, Technology & Sciences, Pray4agraj to study the “ Effect of foliar application of plant growth regulators on flowering, growth, fruit set, fruit drop, yield, quality of Kinnow Mandarin (Citrus reticulate ). The research was conducted under the Prayagraj Agro climatic conditions and Randomised block design is followed. The Experiment was conducted on Kinnow mandarin with various treatments (Control, NAA-25ppm, 52ppm, 75ppm, 100, 2,4-D -5ppm, 10ppm, 15ppm, 20ppm, GA3- 25ppm, 50ppm, 75ppm, 100ppm) in three replications. The Maximum plant height ranged from (211 .18cm to 240.04cm). The Minimum plant height ( 167.31cm) was recorded in control ( water spray) compared to the other treatments. Based on the results recorded during the trial the most number of flowers obtained after the spraying of growth regulators are (188.56), the maximum number of fruits per plant (171.93), the maximum fruit weight per plant (126.93), the maximum fruit length per plant (6.16cm) was found superior in the plants treated with 2,4-D 20ppm. The minimum fruit drop was recorded in T8 at 20 ppm (12.07%). Among these treatments, the most effective treatment of foliar spray for plant height (cm) number of flowers, fruits per plant, fruit weight, fruit drop, fruit length is 2,4-D at 20ppm.
