| dc.description.abstract | An experiment was conducted at the mango orchard of Basherhat, near the Hajee
Mohamma Danesh Science and Technology University, Dinajpur during March to July,
2017. The chemical analyses were conducted at Bangladesh Atomic Energy
Commission, Agargaon, Dhaka and others parameters were conducted at Department of
Horticulture, HSTU, Dinajpur, Bangladesh. The experimental treatment was arranged as
a two-factor experiment, where factor „A‟ was different bagging times (viz. Bagging at
35, 45 and 55 days after fruit set) and factor „B‟ was different pre-harvest bagging
materials (viz. T0: Non-bagged (control), T1: Brown paper double layered bag (BPB), T2:
White paper single layered bag (WPB) and T3: Perforated transparent polythene bag
(TPB).The experiment was laid out in the randomized completely block design with
three replications (10 plants per replication) with a unit of 5 fruits per treatment per
replication. The result showed that the pre-harvest bagging with brown paper bag and
white paper bag at 35 days after fruit set contributed for best results for infestation of
fruit fly infestation. When 45 days after fruit set gave best performance for total weight
loss, pulp and stone weight, pH, total sugar, colour, appearance, shelf life, number of
fruit immature fruit inside the bag and decreased infestation of fruit fly, disease of stem
end rot, anthracnose .The white paper bag contributed best performance for total soluble
solid. At 55 days after fruit set, brown paper bag and white paper bag improved total
weight loss, pulp and stone weight, total soluble solid, pH, total sugar, number of fruit
immature fruit inside the bag and decreased disease of stem end rot, anthracnose. It is
advisable to use brown paper bag for getting colored fruits i.e., yellow colour since white
paper bag for retains original colour of each variety. Both bags showed their potentiality
against major insect-pests and diseases attack. Bagging fruits have a good shelf life
which is important criteria for exportable mango. On the other hand, bagging fruits
having attractive colour, farmer will get more market prices for their mangoes.
Therefore, farmers might be used this technology for commercial mango cultivation for
fulfill demand of quality mango in country and abroad. | en_US |
