Abstract:
The present investigation was carried out at Fruit Research station Aurangabad, during Ambebahar of the year 2020-21.The experiment was laid out in Randomized Block Design (RBD) with nine treatments replicated thrice. Two foliar spray of plant growth regulators and micronutrients at pea and marble stage of fruit development. The result of the investigation revealed that, different treatment showed positive response on chemical quality attributes of mango. The maximum value of chemical quality parameters like total soluble solids (18.7%), total sugar (15.20%), reducing sugar (4.57%), non-reducing sugar (10.63%), TSS: acid ratio (74.8) were reported in treatment T₁ i.e. (GA₃ 35 ppm). The minimum titratable acidity was observed under treatment T₁ and T₅i.e. (0.25%). The maximum ascorbic acid content reported in treatment T₈ (NAA 25 ppm + Borax 0.2%) i.e. (46.38 mg/100 g). The minimum physiological loss in weight of fruit was reported in treatment T₄ (triacontanol 750 mg/l) i.e. (6.41%) which was superior over treatment T₉ (9.16%).
