An investigation was undertaken to study the effect of different types of bag for pre-harvest bagging on physico-chemical properties of mango cv. Kesar during 2012-2014. Egg size fruit (45 days after fruit set) were randomly selected for bagging. The field experiment was conducted in Randomised Block Design with 7 treatments of different types of bags viz, T1: Newspaper bag; T2: Brown paper bag; T3: Polythene bag; T4: Butter paper bag; T5: Muslin cloth bag; T6: Scurting bag; T7: Control (no bagging). All the treatments were replicated three times with a unit of 30 fruits per replication per treatment. All types of bag improved fruit retention, fruit weight, fruit diameter, pulp weight, TSS, reducing sugars and total sugars of mature fruits. The sensory qualities were maintained by bagging treatments. The disease incidence and pests were significantly reduced by preharvest bagging. Among the different types of bag newspaper and scurting bags were found to be meritorious.
