Description A field experiment was conducted to study the “Effect of pre-harvest
chemical treatments and mulching on quality and marketability of mango fruits
cv. Amrapali”. At the Horticulture Research Station, OUAT, Bhubaneswar,
Odisha, having the costal humid climate, the experiment was laid out in a
randomized block design. Ten-year-old mango plants cv. Amrapali with
uniform vigor and size were selected for the experiment. Black LDPE
mulching of 100 micron thickness film was carried out in September as per the
treatment and spraying of nutrients were done 30 days before the anticipated
date of harvest. Seven number of treatments were (T1) black LDPE mulching;
(T2) black LDPE mulching + CaCl2 @ 2.0%; (T3) black LDPE mulching +
CaCl2 @ 4.0%; (T4) black LDPE mulching + CaCl2 @ 6.0%; (T5) black LDPE
mulching + Ca (No3)2 @ 4.0%; (T6) black LDPE mulching + borax @1.0% and
(T7) control (water spray without mulching). It was revealed that spraying of
1.0% borax along with black LDPE mulching (T6) exhibited highest fruit
weight (262.56g) followed by (248.67g) in CaCl2 @ 2.0% + black LDPE
mulching. The same treatment (T6) borax @ 1.0% along with mulching was
also found to increase the TSS (18.810Brix, 22.100Brix), reducing sugar
(3.27%, 5.14%), total sugar (12.12%, 19.03%) and decrease the acidity (0.34%,
0.19%) at the time of harvest and end of the storage period respectively. On
12th day of storage the maximum fruit marketability (90.58%), minimum fruit
decay (8.55%) and minimum physiological loss of weight (15.13%) was
recorded in treatment (T2) CaCl2 @ 2.0% along with black LDPE mulching.
Therefore, the use of black LDPE mulch material in September along with
borax @1.0% spray at 30 days prior to harvest is found to improve fruit quality
significantly, whereas (T2) CaCl2 @ 2.0% is found effective for improving fruit
marketability, reducing decay percentage and reducing physiological loss in
weight of the fruit during storage in mango cv. Amrapali. However the
experiment needs a further continuance without modification of treatments for
another season to get the results for conformity.
