Foliar application of plant growth regulators (PGRs) is one tactic for nourishment which directly enhances nutrient uptake, leading to a more balanced supply and improved accumulation in ultimately improving quality yield. The current research covers see the response biochemical phytochemical parameters sapota cv. DHS-1; pre-harvest spray PGR i.e. naphthalene acetic acid (NAA) (50 100 ppm), 2-chloro-4-pyridyl) N'-phenyl urea (5 7.5 salicylic (SA) (150 300 ppm) homo brassinolide (10 15 ppm); sprayed at flowering, pea stage marble growth. Treatments were imposed on 24-years-old, uniformly grown, trees, planted 10m x spacing, Central Horticultural Experiment Station, (ICAR-IIHR), Bhubaneswar during 2022 2023. In general, PGRs foundaffecting fruit significantly over control. However, NAA CPPU performed better higher dose. treatment ppm resulted highest total soluble solids (°Brix), TSS: acid, ascorbic content, sugar content minimum titratable acidity (%). Further, found be most effective boosting flavonoids phenol antioxidant activity. possible correlations among these discussed showed that bio-active compounds such as vitamin C, flavonoid contributed towards anti-oxidant capacity fruit. Therefore, effectively augment by both properties when compared
