The influence of foliar application of calcium chloride and borax on the fruit quality of litchi cultivars was investigated by applying1-3% Calcium either alone or in combination with 0.5 to 1.5 Borax. The litchi cultivars varied significantly for quality traits . Cultivar Gola had the highest fruit weight (23.54 g), pulp weight (17.16 g), TSS (22.54%), total sugars (21.45%), reducing sugars (17.96%) and specific gravity (1.1051), while cultivar Bedana had the highest non-reducing sugars (9.72%). Foliar application of calcium chloride (CaCl2) alone had no significant effect on most of the quality variables, however, CaCl2 + Borax (Na2B4O7·10H2O) application increased the fruit weight (19.87 g), pulp weight (14.88 g) and pulp dry weight (13.76%) in control fruits to the maximum of 20.79, 15.69 g and 15.40% respectively with CaCl2 (3%) + Borax (1.5%). No variations were observed in total sugars, reducing sugars and non -reducing sugars of litchi fruit with application of CaCl2 alone, which increased significantly with foliar application of CaCl 2 3% + Borax. The planned paired means comparison showed that the least fruit weight (19.87 g), pulp weight (14.88 g) and pulp dry weight % (13.76% ) of control fruits increased significantly to 20.10 g, 14.94 g and 13.93% with CaCl2 application and further to 20.54 g, 15.38 g and 15.08% with CaCl2 + Borax treatments. The fruit weight, pulp weight and pulp dry weight % was significantly higher with CaCl2 + Borax foliar application as compared to CaCl2 alone. The total sugars, reducing sugars and non-reducing sugars were not significantly affected by CaCl 2 application but were significantly higher in Control vs. Rest, Control vs. CaCl2 + Borax and Ca vs. CaCl2 + Borax treatments means.
