Abstract:
The present experiment was conducted to study the e
ffect of pre-harvest bagging and
spray of CaCl
2
and K
2
SO
4
on quality and shelf life of mango fruits
cv
. Amrapali during
two succeeding years. Trees of Amrapali mango were
sprayed three times at 30, 20, and10
days before harvesting and bagging with brown paper
bag 20 days before harvesting of
fruits. Harvested fruits were stored under the ambi
ent temperature (storage at room
temperature) and observations were taken at three d
ays intervals upto 18 days. The
results indicated that the pre-harvest treatment of
2% CaCl
2
+1% K
2
SO
4
+bagging was
found superior to improve the quality of fruits in
respect of highest fruits weight,
firmness, TSS, ascorbic acid, total sugars, and
β
-carotene content with minimum black
spotted fruits per cent and maintained it throughou
t the storage period upto 18 days.
Fruits treated with 2% CaCl
2
+1% K
2
SO
4
+bagging showed shelf life up to 12 days with
lowest weight loss and highest organoleptic quality
as against 6 days of untreated fruits
(control).
