A study was conducted at RHRS farm, Navsari Agricultural University, Navsari during the year 2016-17 to investigate the effect of different silicon sources and salicylic acid on quality of mango fruits cv. Kesar. The experiment was laid out in a Randomized Block Design with ten treatments and replicated thrice. Trees were subjected to foliar sprays of potassium silicate (1, 2 and 3 ml/l), silicic acid (2, 3 and 4 ml/l), salicylic acid (1500, 2000 and 2500 ppm) and unsprayed control. Result indicated a significant impact of treatments on all parameters included in the study except total carotenoid content. Trees sprayed with salicylic acid at 2000 ppm recorded the highest TSS (19.40oBrix), total sugar content (24.83%), reducing sugars (4.87%) and non-reducing sugars (19.96%) after 16 days of storage under ambient conditions. For that very storage period, salicylic acid @2000 ppm had the minimum PLW (19.20%) and titrable acidity (0.193%). Fruit treated with salicylic acid could be kept for about 18 days without any apparent loss in quality. This study high lights the possibility of using salicylic acid at 2000 ppm for improving fruit quality and enhancing shelf life of mango fruits cv. Kesar.
