The present investigation entitled �Effect of plant growth regulators on chemical composition 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 GA3 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. Qualitative characters like TSS (21.61%) and ascorbic acid (57.63 mg/100g) increased with the foliar application of 35 ppm 2,4-D and 35 ppm NAA respectively. While, reducing sugar( 5.71%) , non-reducing sugar (14.26 %) and total sugar (19.97 %) were increased with 35 ppm foliar application of 2,4-D. Acidity content of fruit (0.17 %) was recorded minimum under the superiority of treatment foliar application of 2,4- D at 35 ppm concentration. Among the different concentrations of plant growth regulators; the foliar application of 35 ppm 2, 4-D were found to be optimum concentration by which chemical composition of fruits can be significantly influenced.
