Abstract:
The study was conducted to determine the extent of effects of using selected postharvest
practices as perceived by the farmers and explore the contribution of the
selected characteristics of the farmers to their perceived effects of using selected postharvest
practices to strengthen vegetable export market. The study was conducted in
three upazilas namely Belabo, Raipura and Shibpur under Narsingdi district in
Bangladesh. A total of 717 farmers of these three upazilas are actively producing and
exporting Bitter Gourd, Brinjal and Teasel Gourd with the help of Bangladesh Fruits,
Vegetables and Allied Products Exporter’s Association (BFVAPEA) which
constituted the population of the study. By using sample size formula, 250 farmers
founded the sample of the study. Proportionate random sampling technique was used
for selecting sample farmers from farmers’ group formed by BFVAPEA in different
villages of different unions of these three selected upazilas. Finally 91, 75 and 84
farmers were included for Bitter Gourd, Brinjal and Teasel Gourd respectively as the
sample. Data were collected from a sample of 250 farmers during August 01, 2019 to
November 30, 2019 by using an interview schedule. Nineteen (19) selected
characteristics of the farmers were considered as the independent variables. Effects of
using selected post-harvest practices to strengthen vegetable export market was the
dependent variable. Majority (83.60%) of the farmers perceived that the use of
selected post-harvest practices was medium to high effective to strengthen vegetable
export market. Stepwise multiple regression analysis indicated that the whole model
of 19 variables explained 35.90 percent of the total variation in effects of using
selected post-harvest practices to strengthen vegetable export market as perceived by
the farmers. But since the standardized regression co-efficient of 6 variables formed
the equation and were significant, it might be assumed that whatever contribution was
there, it was due to these 6 variables. Results of stepwise multiple regression analysis
showed that use of selected vegetables post-harvest practices, knowledge on selected
vegetable post-harvest practices, exportable vegetables production, experience in
exportable vegetables production and extension contact had significant positive
contribution whereas problems faced in vegetable value chain had negative
contribution to their perceived effects of using selected post-harvest practices to
strengthen vegetable export market. Path analysis indicated that knowledge on
selected vegetable post-harvest practices had the highest total indirect effect followed
by extension contact, use of selected vegetables post-harvest practices, experience in
exportable vegetables production and exportable vegetables production on their
perceived effects of using selected post-harvest practices to strengthen vegetable
export market. Problems faced by the farmers had negative total indirect effect on
their perceived effects of using selected post-harvest practices to strengthen vegetable
export market. Finally, it was found that use of selected post-harvest practices was
effective to strengthen vegetable export market.
