Investigations on seven year old Santa Rosa plum orchard were carried out near SKUAST-Kashmir, Shalimar Campus, Srinagar during 2012 and 2013, to examine the storage behavior of Santa Rosa plum as affected by nitrogenous fertilizer and boron. Urea @ 500 g (N1), CaNO3 @ 1450 g (N2), N1 + 50 g boron (N3) and N2 + 50 g boron (N4) were applied at T1 = Full dose in spring, T2 = Full dose after harvest and T3 = 3/4 dose in spring and 1/4 dose after harvest. Observations were recorded on PLW, total soluble solids, acidity, total sugars and organoleptic ratings at 4, 8, 12, 16 and 20 days of storage. After four days of storage minimum physiological loss in weight (2.89 %) was observed when full dose of calcium nitrate (1450 g) and boron (50 g) was applied in spring whereas maximum total soluble solids (13.0 %) was recorded when 50 g boron along with ¾ dose of calcium nitrate was applied in spring and ¼ dose after harvest i.e. N4T3 treatment. Reverse trend was recorded after 8 days of storage and onwards upto 20 days for physiological loss in weight and total soluble solids. No statistically significant results were noticed with respect to acidity. N4T1 treatment i.e. full dose of calcium nitrate (1450 g) and boron (50 g) was applied in spring recorded maximum total sugars (2.71 %) after 4 days of storage. Similar trend was recorded for total sugars at 8, 12, 16 and 20 days of storage. Application of calcium nitrate @ 1450 g in spring was beneficial for minimum physiological loss in weight and maximum total soluble solids and total sugars for storing Santa Rosa plum for 20 days under ambient conditions.
