This experiment was conducted in the experimental area of BAU Sabour, Bhagalpur, Bihar, in the
year 2021-22 to see the effect of calcium chloride (1.5% and 3.0%) and chitosan (0.5% and 1.0%)
alone and their combinations on the yield and bioactive compounds of mango (Mangifera indica
L.) cv. Mallika. These chemicals were sprayed on the 15th and 30th days before harvesting. These
chemicals were choosen to enhance the quality and shelf-life of mango for longer duration
availability to consumers. The results of the study clearly showed that fruit morphology, such as
fruit length, breadth, volume, and weight (155 mm, 95 mm, 532 ml, 561.53 g), were recorded at
maximum with T 8 : CaCl 2 3% + chitosan 1%. It was also found that this treatment had the highest
yield (28.33 fruits/plant). Minimum peel percent (14.30) was observed in T 6 : CaCl 2 21.5% +
chitosan 1%, whereas minimum stone percent (8.99) and maximum pulp percent (76.86) were in
T 8 : CaCl 2 3% + chitosan 1%. Highest TSS, TSS: acid ratio, total sugar, reducing sugar, and
ascorbic acid (13.46 o Brix, 21.36, 3.79%, 1.78%, and 60.86 mg/100g pulp, respectively) were also
in T 8 , while phenol, anthocyanin, and antioxidant content (49.36 mg GAE/g pulp, 0.82 mg/100g
peel, and 1.28 µmol Trolox equivalent/g pulp) were in T 7 : CaCl 2 3% + chitosan 0.5%.
