The present investigation entitledEffect of plant growth regulators on fruit retention and fruit drop of mango (Mangifera indica L. ) cv. Dashehari. was carried out at the instructional Farm, Deptt. of Horticulture, College of Agriculture, IGKV, Raipur (C. G. ) during the year 2017-18 employing Randomized Block Design with three replications. Three levels of NAA i. e. , 15, 25 and 35 ppm, three levels of GA 3 i. e.15, 25 and 35 ppm and three levels of 2, 4- D i. e.15, 25 and 35 ppm were sprayed at pea and marble stage of fruit development. All the treatments significantly influenced the number of fruits retained at pea, marble and harvesting stage of fruit growth and development as compared to the control. Foliar application of 35 ppm GA 3 at pea and marble stage of fruit development increased the fruit retention percentage (15.23 %) and reduced the fruit drop percentage (84.77 %).
