Abstract:
The study was conducted at the laboratory of the Sher-e-Bangla Agricultural
University (SAU), Dhaka during the period from July 2018 to assess the
postharvest management of ‘Harivanga’ mango variety to increase shelf life and
quality. The popular Mango variety ‘Harivanga’ were used as experimental
materials for the study. The experiment comprised of 19 different postharvest
practices as treatment and T
1
: Control condition (no postharvest treatments and
stored in open condition). T
8
treatment given the highest result and T
8
: Stored in
low density perforated polybag after Bavistin dips treatment. Data were recorded
on shelf life and different quality parameters and statistically significant
differences were observed for different treatments. The highest shelf life (15.67
days) was observed from T
8
treatment, whereas the lowest shelf life (9.00 days)
was recorded from T
1
treatment. At 3, 5, 7 and 9 days after harvest (DAH), the
highest moisture content (85.44%, 83.36%, 82.18% and 80.14%, respectively)
was found from T
8
treatment, whereas the lowest moisture content (81.76%,
80.22%, 78.66% and 75.85%, respectively) was observed from T
1
treatment. At
3, 5, 7 and 9 DAH, the highest total soluble solids (TSS) (16.34%, 20.83%,
23.55% and 26.12%, respectively) was recorded from T
8
treatment, whereas the
lowest TSS content (13.02%, 16.82%, 19.46% and 21.55%, respectively) was
observed from T
1
treatment. At 5, 7 and 9 days after harvest (DAH), the highest
disease incidence (33.33%, 58.33% and 100.00%, respectively) was recorded
from T
1
treatment and the lowest disease incidence (0.00%, 0.00% and 8.33%,
respectively) was observed from T
8
and T
9
treatments. So, consideration of shelf
life and quality treatment T
8
as stored in polybag after Bavistin dips treatment
were superior on other treatment for ‘Harivanga’ mango.
