An experimental study was conducted to observe the effects of post-harvest treatments which extend the shelf life and maintain the quality of Indian jujube cv. Umran under ambient storage conditions. The results revealed that calcium chloride and SA significantly reduced the physiological loss in weight during ambient storage condition in Ber fruits. Application of 1.5 per cent calcium chloride on Ber fruits packed in nelton bag exhibited minimum weight loss is during storage period in ambient storage conditions. The application of CaCl₂ and SA significantly influenced the pulp/stone ratio under ambient storage conditions in Ber fruits. The CaCl₂ @ 1.5 per cent (T₃) was recorded maximum i.e., 11.51, 11.39, 11.10 and 10.29 pulp / stone ratio at 3^rd, 6^th, 9^th and 12^th days under ambient storage conditions, respectively. The maximum TSS was recorded under T₃ treatment (1.5% CaCl₂) i.e., 13.36, 14.56, 14.89 and 13.95 °B at 3^rd, 6^th, 9^th and 12^th days of storage, respectively. The maximum acidity i.e., 0.253, 0.232, 0.221 and 0.171 per cent was recorded in T₃ (1.5% CaCl₂) while minimum i.e., 0.189, 0.159, 0.129 and 0.108 per cent under control at 3^rd, 6^th, 9^th and 12^th days of storage period under ambient storage conditions. The application of CaCl₂ at the rate 1.5 per cent decreased the TSS / acid ratio of 18.33 per cent on 12^th day of storage as compared to control. The reducing sugar increased during storage time up to 9th day but decreased on 12^th day of storage in all treatment combinations of Ber fruits. This treatment of application of CaCl₂ showed an increased 68.60 per cent more reducing sugar over control at 12^th day under ambient storage conditions. The maximum non reducing sugar content in Ber fruits i.e., 4.85, 5.39, 5.55 and 4.85 per cent at 3^rd, 6^th, 9^th and 12^th days of storage was recorded under T₃ (1.5% CaCl₂) during ambient storage conditions, respectively.
