The experiment was carried out at horticulture laboratory, Gokuleshwor, Baitadi during 28th December 2018 to 19th January 2019, to study the effect of post harvest treatments on quality and shelf life of sweet orange (Citrus sinensis) cultivar Local. It was carried out in Completely Randomized Design (CRD) with five treatments of different types of post harvest treatments viz. T1 = control (distilled water), T2 = bavistin (0.1%), T3 = calcium chloride (1%), T4 = Jeevatu (5%) and T5 = cinnamon oil (2%) replicated four times. Among these post harvest treatments, T1 showed highest percentage of weight loss (15.83%), lowest firmness (2.22 kg/cm2) and highest TSS (10.70˚ Brix), lowest TA (0.395%) at final day of storage as compared to other treatments. Bavistin was found as the most effective in reducing the physiological loss in weight (10.80%), retained maximum firmness (3.13 kg/cm2), highest tritrable acidity (0.76%), highest pH (5.08). The minimum total soluble solid (8.75˚Brix) was retained by cinnamon oil. This study revealed that sweet orange treated with bavistin recorded lowest physiological loss in weight (31.77%) and retains more firmness (24.73kg/cm2) than that of control .Thus, present findings indicate that sweet oranges treated with bavistin increase the shelf life where as cinnamon oil also found to be promising treatment for retaining the quality of the sweet oranges stored up to 28th days under laboratory condition.
