An experiment was conducted to study the effect of preharvest sprays of calcium compounds and growth regulator on sapota trees at 50 % of the fruit maturity (4 months after fruit set). Various physical parameters like physiological loss in weight, number of days for ripening, firmness, ripening, shelf life, spoilage were estimated. Among these treatments results proved that pre-harvest spray of Gibberellic acid 1000 ppm (T5) on sapota exhibited low PLW (7.34 %) and highest shelf life (12.67 days). Pre-harvest spray of Calcium chloride 2% (T2) showed maximum firmness (0.26 kg/cm2), minimum ripening percent (75.89 %). Pre-harvest spray of Calcium chloride 1% (T1) showed minimum spoilage (58.23 %), pre-harvest spray of Calcium nitrate 1% (T3) and Calcium nitrate 2% (T4) showed highest number of days taken for ripening (9.17 days).
