Abstract:
The experiment was carried out at the Post-harvest Laboratory, Dr. M.A.
Wazed Miah Research Centre, Department of Horticulture, Sher-e-Bangla
Agricultural University, Dhaka. The experiment was laid out in a
Completely Randomized Design with three replications. The present
research was conducted on the aspect of shelf life of litchi through six postharvest
treatments (T

and 30th days after storage respectively) was found when litchi fruits
treated with Ice and 2mM oxalic acid with 0.05% fungicide (Bavistin)
solution and packaged with LDPE bag and stored at 5

at the end of shelf life) and the longest shelf life was observed in T

The best performance was observed in the hydro cooled litchi fruits dipped
into 2mM oxalic acid with 0.05% fungicide (Bavistin) solution and
packaged with LDPE bag and stored at 5
