The present investigation entitled, Effect of pre cooling and storage conditions on physiological change of mango (Mangifera indica L.) Cv. Kesar” was carried out at the Horticulture research farm, Department of Horticulture B.A. College of Agricultural- Anand Agricultural University, during the year 2017. The experiment was laid out on Factorial Completely Randomized Design, with three replications. The influence of precooling treatments viz., Control(P₀), ice cooling for 15 minutes(P₁), ice cooling for 30 minutes(P₂), hydrocooling at 10 °C temperature for 15 minutes(P₃) and hydrocooling at 12 °C temperature for 30 minutes(P₄) and Storage Conditions viz., Ambient Conditions(S₀), Zero energy cool chamber(S₁) and Cold storage 13±2 °C(S₂). After treatment, fruits were kept in CFB boxes at different storage condition. The fruits were analyzed periodically for various physiological changes. It can be conclude that The fruits treated with hydrocooling at 12 °C temperature for 30 minutes, proved to be most effective with respect to longest shelf life (25.04 days), lowest percentage of spoilage (10.65per cent at 9th day) and physiological loss in weight (5.82, 9.55, 13.41and 13.41 per cent, respectively) on 3^th, 6^th, 9^th and 12^th day of storage. In cold storage at 13±2 °C reduced physiological loss in weight (5.54, 10.16, 13.91, 12.08, 10.42 per cent and 16.09, 21.7 and 26.16 per cent treatment mean, respectively), enhanced shelf life of fruits (30.35 days), reduced spoilage (5.70, 15.10 and 4.16 per cent and 29.29, 40.40, 49.85 per cent treatment mean respectively) on 3^th, 6^th, 12^th, pooled over periods and 17^th, 22^th, 27^th day of storage.
