AGRICULTURAL EXTENSION & INFORMATION SYSTEMThe main objective of the study was to determine the adoption of Vietnamese Koi by the fish
farmers in Cumilla district. The study area comprised three villages namely Jahapur, Dhamghar
and Paschim nabipur under of Muradnagar upazila. The selected characteristics of the farmers
were age, education, family size, pond size, annual family income, Fish farming experience,
knowledge on Vietnamese koi culture, extension media contact, cosmopolitness, training exposer
on fish farming, attitude towards Vietnamese koi culture and problems faced by the farmers in
Vietnamese Koi culture. Data were collected from randomly selected 105 Vietnamese Koi farmers
during December, 2022 by using structured interview schedule. Correlation was used to measure
the relationship between each of the selected characteristics of the farmers and their adoption of
Vietnamese Koi. The findings indicate that 52.38 percent of the Vietnamese Koi farmers had
medium adoption, 28.56 percent had low rate of adoption and 19.04 percent had higher adoption.
Correlation analysis indicate that farm size, annual family income, fish farming experience,
knowledge on Vietnamese koi culture and attitude towards Vietnamese Koi culture of the farmers
had positive significant relationships with their adoption of Vietnamese Koi. On the other hand,
age, education, family size, extension media contact, cosmopolitness and training exposer of the
fish farmers had no significant relationships with their adoption of Vietnamese Koi. The Problem
Faced Index indicated that high price of feed ranked 1
st
followed by “lack of capital”, “high labor
cost”, “high price of medicine”, “high production cost”, “high sensitivity to disease”, “lack of
knowledge”, “natural disaster”, “lack of water exchange facilities”, “less security of fish food”,
“poor transportation facilities”, Unavailability of Vietnamese koi seeds” and “Algal blooms on the
pond”

DEVELOPMENT AND POVERTY STUDIESMarketing has been a challenge for any kind of business around the world due to its
cost. Traditional marketing which involves television, radio and billboards come at a
cost way high for the agri-entrepreneurs and therefore growth of these companies
becomes a challenge. Digital marketing has provided entrepreneurs a platform to create
awareness to consumers on what they offer due to their relatively low cost. This study
empirically examines the factors affecting the adoption of digital marketing by agrientrepreneurs
in Bangladesh. The study obtained a list of SME foundation of agrientrepreneurs
in Bangladesh which was about 300 agri-entrepreneurs. From this list,
this study selects on 80 by random sampling method technique Data for this study were
collected through face-to-face interview during November, 2022 to February, 2023
using the structured questionnaire. Both descriptive and statistical tools were used in
this study. Data were analyzed by using STATA software. The findings show that
technological factors, organizational factors, business environment, relative advantage,
perceived ease of use, and entrepreneurs characteristics have significant influence on
the adoption of digital marketing. The study provides a clear understanding of
entrepreneur’s perception about digital marketing adoption in their businesses. It was
observed that the entrepreneurs faced some problems like lack of digital marketing
knowledge, lack of relevant technique, lack of finance etc. The study recommended
that agri-entrepreneurs should be trained and sensitized on the available digital
marketing techniques and how they are suitable for their businesses. The study also
recommended that proper policies should be made by the government that assist agrientrepreneurs
to adopt digital marketing. Finally, the study recommended that agrientrepreneurs
should
be

AGRICULTURAL ECONOMICSThis piece of research was undertaken in order to assess the comparative profitability
and resource use efficiency of onion and garlic production in Shariatpur District. A
total number of 60 farmers were randomly selected. Necessary statistical analyses were
performed to achieve the objectives of the study. The Cobb-Douglas production
function was used to determine the effects of individual inputs on and resource use
efficiency of onion and garlic production. Per hectare total return for onion and garlic
was about Tk.557023 and Tk. 665706, gross margin was about Tk. 361507 and Tk.
447925 and the net return was about Tk. 286487 and Tk. 371438 respectively. The
undiscounted benefit cost ratio (BCR) was 2.06 and 2.26 for onion and garlic
production respectively. The results indicated that garlic production was more
profitable than the onion production. The net return was influenced by most of the
factors included in land preparation, human labor, seed, fertilizer, irrigation and
machinery. The return to scale of onion and garlic production was 1.46 and 1.10
respectively. This implies that the production function exhibits increasing return to
scale. Resource use efficiency indicated that all of the resources were under used for
onion production except overutilization of seed or bulb and zinc fertilizer. On the other
hand, it indicated that all of the resources were under used for garlic production except
overutilization of MoP fertilizer. Farmers producing onion and garlic faced problems
related to production and marketing of the crops. It may be concluded that the farmers
should be encouraged to grow more garlic rather than onion as a means of increasing
farm income through diversification of crop production in the area under study

of Indian mustard. The experimental set up was organized at Sher-e-Bangla Agricultural
University, Dhaka during the Rabi season 2022/23 for evaluation of these populations
which was preceded by a generation advancement and a backcross program performed
in previous Rabi 2021/22 through which the seeds for these populations were
developed. In the study twelve yield attributing traits were observed and they had
shown significant variation among all the populations. Considering the mean
performance G1 (26.44 gm) of BC

population showed the most promising result. A
lower environmental variance was found to be associated with all of these traits.
Majority of the traits had also shown a higher phenotypic coefficient of variation and
genotypic coefficient of variation. Higher heritability as well as higher genetic advance
was also found to be associated with all of the traits and among them the maximum
heritability coupled with a higher genetic advance as percentage of mean was observed
with yield per plant (98% and 63.26%) and number of primary branches per plant (98%
and 62.70%). Finally, the correlation study revealed that plant height (0.52), number of
primary branches (0.66), number of secondary branches (0.66), siliquae length (0.30),
thousand seed weight (0.60) and harvest index (0.30) had a highly significant
correlation with yield in a positive manner. Furthermore, the path coefficient study
unveiled that, majority of the traits had a positive direct effect on the yield among which
the number of primary branches (0.578) had the maximum direct effect along with a
highly significant positive correlation with the yield. Considering altogether, G1 and
G5 of BC

DIVERSITY AND DNA BARCODING OF CORAL-ASSOCIATED FISHES OF SAINT MARTIN'S ISLAND FOR EFFECTIVE CONSERVATION OF MARINE LIFE
Get PDFAbstract
Saint Marin's Island (SMI), is the only sedimentary continental island in
Bangladesh. We have conducted an ichthyological survey to assess the reefassociated
fish species on this island. In this survey, we have identified and
recorded 141 species of reef-associated fishes of 56 Families under 20 Orders.
Among them, 37 species of reef fishes were recorded for the first time in
Bangladesh and one is discovered as a new species to the science during the
current study. In this study, we also obtained 221 DNA sequences from 100
species of which 179 sequences (96 species) were obtained from the COI gene
and 42 sequences (26 species) obtained from the 16S rRNA gene region. The COI
sequences of those 96 species comprised 145 haplotypes with 337 polymorphic
sites. The mean genetic distances within species, genera, and families were
0.34%,12.26%, and 19.03%, respectively. In the case of 16S rRNA sequences, 42
sequences of 26 fish species comprised 31 haplotypes containing 241
polymorphic sites. The mean genetic divergence within species, genera and
families was 0.94%, 4.72% and 12.43%, respectively. This study is a significant
contribution to the fisheries statistics of this ecologically critical area (ECA) and
Marine Protected Area (MPA) of Bangladesh as well as the nOithem Bay of
Bengal which would facilitate the assessment of species catch composition and
hence for strategizing management plans. It is also an important input to the DNA
barcode library of reef fishes of the northem Bay of Bengal and to the marine
fishes of Bangladesh as well as global DNA barcode entries in general.

BIOTECHNOLOGYMung bean (Vigna radiata (L.) R. Wilczek) has been widely used as a pulse crop. The
study was carried out at the Biotechnology laboratory of Sher-e-Bangla Agricultural
University, during the period of July 2021 to June 2022 to investigate molecular diversity
and fingerprinting of fifteen mung bean germplasm. RAPD primers were selected and
synthesized for molecular diversity analysis. All of the primers were able to produce
polymorphic bands. The highest number of bands were observed in RAPD primer OPT20.
The polymorphic Information Content (PIC) of RAPD markers ranged from 0.24 to
0.32 with an average value of PIC =0.27. Gene diversity ranges from 0.41 to 0.28 with an
average value of 0.33. Primer showed OPBC-1, OPA-20, OPP-03, OPT-20 moderate
diversity and primer OPBC 18 showed low diversity on the basis of PIC value. The value
of pair -wise comparisons of Nei’s (1983) genetic distance (D) among 15 genotypes was
computed from and it was ranged from 0.1034 to 0.6207 with an average of 0.3621.
Dendrogram based on Nei’s genetic distance using unweighted Pair Group Method Of
Arithmetic Mean (UPGMA) indicated the segregation of 15 genotypes into four main
clusters. This result can be conveniently used for molecular diversity analysis to identify
diverse parent for mung bean improvement program

. The analysis of
various data revealed that significant differences were observed in groundnut growth,
yield, and quality characteristics as a result of nitrogen and sulphur application doses and
their treatment combination. In case of different levels of nitrogen application the highest
pod yield (2.06 t ha
-1
), kernel yield (1.65 t ha
-1
), seed protein content (27.14 %), seed oil
content (49.59 %), seed nitrogen content (4.34 %), seed sulphur content (0.27 %) and
seed germination percentage (90.58 %) were reported in N

treatment followed by N
treatment. Seed yield and quality of parameters of groundnut increased with increased
sulphur fertilizer application and the highest pod yield (1.95 t ha
-1
), kernel yield (1.56 t
ha
-1
), seed protein content (24.79 %), seed oil content (46.16 %), seed nitrogen content
(3.97 %), seed sulphur content (0.24 %) and seed germination percentage (91.42 %) were
recorded in S
treatment. In respect of the combination effect, the highest pod yield (2.37

), kernel yield (1.95 t ha
-1
), seed protein content (29.56 %), seed oil content (51.62
%), seed nitrogen content (4.73 %), seed sulphur content (0.29 %) and seed germination
percentage (96.33 %) were achieved in N

treatment combination. However N
treatment combination showed statistically similar results in pod yield and N
treatment combination showed statistically similar results in nutrients content in
groundnut seed. Therefore it may be concluded that both nitrogen and sulphur had
beneficial effect on yield and quality seed production of groundnut. Application of
nitrogen (25-30 kg Urea ha
-1
) and sulphur (300-350 kg Gypsum ha
-1
) along with their
combination exhibited the best performance on yield and quality seed production
compared to other treatment combination
