DEVELOPMENT AND POVERTY STUDIESThe main objective of the study was to measure the comparative profitability and
technical efficiency of combine harvester (CH) user and non-user farmers in Boro rice
production. Using a simple random sampling technique, data were collected from 120
Boro rice producing farmers through face-to-face interview from Sunamganj and
Netrokona districts of Bangladesh during March to April, 2023. Descriptive statistics
and econometric model were used to analyze the data. The technical efficiency of
combine harvester users and non-users in Boro rice farming was estimated using the
stochastic frontier production function. The study's key findings demonstrated that
growing Boro rice was profitable for both combine harvester users and non-users. But
users of combine harvesters earned greater profits than non-users. The average total
cost of Boro rice production per hectare was estimated Tk. 115506 and Tk. 123317 for
combine harvester users and non-users, respectively. For users of combine harvesters,
the average gross return and net return per hectare were Tk. 153279 and Tk. 37773,
respectively, whereas for non-users, the average was Tk. 141362 and Tk. 18045. The
estimated BCR was higher for combine harvester users (1.33) than non-users (1.15).
Combine harvester users would save 75% labour (27 labourers) per hectare compared
to non-users. The findings also indicate that agricultural inputs like irrigation, urea and
MoP had positive but human labour, seed, TSP and DAP had negative effects on CH
users in Boro rice production. For non-users of CH, land preparation and MoP had
positive but TSP, DAP and gypsum had negative effects on Boro rice production.
According to the estimated inefficiency model, both for CH users and non-users,
education, market distance, farming experience and organizational membership had
negative effects indicating these factors help reducing technical inefficiency in Boro
rice farming. The above results revealed that mechanized harvesting through combine
harvester contribute to save money, time and labour. Outcome of this study will help
the policymakers to shape the policy interventions which in turn help to improve the
production and facilitate the goal of doubling farmers’ income and productivity which
is targeted at the SDG 2.3

of January 2021 to December 2021, to study the micro propagation of sweet potato
(Ipomoea batatas L.) in a new plant tissue culture medium (SAU tissue culture medium). Six
different culture media were compared to explore the potential of SAU Tissue cult ure
medium for regeneration of sweet potato. Data were recorded on the percentage of
regeneration, days to shoot initiation, and the number of shoots per explant at different time
intervals. The SAU tissue culture medium showed best performance for all the parameter
under study among the two other treatments MS (1962) medium and MS powder medium.
The results showed that SAU Tissue Culture Medium supplemented with 1.00 mg/L
KIN+2.00 mg/L NAA had the highest percentage of regeneration (90%), shorter days to
shoot initiation (12.33 days) as compared to other treatments. The highest number of leaves
per explant (11.33) and maximum length of shoot (9.2cm) were also observed in the same
medium at 35 DAI. In regenerated plantlets 90% survival was found in growth chamber, 85%
survival under shade house and 80% in open field condition. Micropropagation of sweet
potato was successfully done in SAU tissue culture medium which can be utilized for large
scale plantlet production program

SEED TECHNOLOGYAn investigation was conducted on hot water seed treatment of rice, wheat and
maize seeds in controlling seed infection for proper germination during the period
from July 2021 to December 2022, at the central laboratory of the Department of
Plant Pathology, Sher-e-Bangla Agricultural University, Dhaka-1207.Suitable
temperature and time for seed treatment were determined. Irrespective to the
cereal seeds, the temperature and time of treatment had shown significant effect
on reduction of seed infection and increase of seed germination. The hot water
treatment also had remarkable effect on rotten seeds, dead seeds and abnormal
seedlings. The experimental treatments were T

= Hot water at 52℃ for 5 and 10
min, T
2
= Hot water at 54℃ for 5 and 10 min, T
3
= Hot water at 56°C for 5 and 10
min, T
4
= Hot water at 58℃ for 5 and 10 min, T
5
= Hot water at 60℃ for 5 and 10
min and T
6
= Control (Using normal water at ambient temperature (25±1°C)). Data
were collected on % seed germination, % seed infection, % rotten seed and %
dead seed. The experiments were conducted following Completely Randomized
Design (CRD) with 4 replications. In case of rice seed, the highest seed
germination (91%) and the lowest seed infection (0%) were noted at 56°C for 5
min while (94%) seed germination and (0%) seed infection were recorded at 54°C
for 10 min. In case of wheat seed, the highest seed germination (88%) and the
lowest seed infection (0%) were recorded at 54°C for 5 min while it was (90%)
seed germination and (0%) seed infection at 52°C for 10 min. In case of maize
seed, the highest seed germination and the lowest seed infection respectively were
(82%) and (0%) at 58°C for 5 min while it was (84%) seed germination and (0%)
seed infection at 56°C temperature for 10 min. In case of rice, Fusarium spp and
in case of wheat & maize, Bipolaris spp was found. Irrespective to the cereal
seeds, the seed infection was found to be reduced with the increase of temperature
and time. The percent dead seed also increased with the increase of temperature.
Thus, the rice seed should be treated with hot water at 56°C for 5 min or 54°C
temperature for 10 min. In case of wheat seed, farmers are suggested to treat with
hot water at 54°C for 5 min or 52°C temperature for 10 min while for maize seed,
farmers are recommended to go through hot water at 60°C temperature for 5 min
or 56°C temperature for 10 min for getting the highest seed germination
minimising the seed infection

AGRICULTURAL ECONOMICSLivestock is one of the sectors in Bangladesh that is expanding the fastest. Dairy farming has
become more important because of its numerous uses. Monthly revenue is guaranteed in dairy
farming. Milk is commonly consumed by humans as it is a good source of nutrients. However,
the supply of milk in our nation does not keep up with the demand. Milk production must be
increased to close the gap between supply and demand. By improving the technical efficiency
of milk production using the existing systems, milk production can be increased. Hence the
objective of the present study was to identify the socio-economic characteristics of dairy
farmers, measure the productivity and technical efficiency of dairy production, and address the
challenges faced by farmers in the study area as well as to suggest policy options to minimize
the problems. A Cobb-Douglas stochastic frontier production function was used to accomplish
these objectives. Primary data was collected from 120 randomly selected farmers from the
Savar Upazila in Dhaka district. The results indicated that the coefficients of parameters such
as family labor cost, hired labor cost, concentrate feed cost, roughage feed cost and utility cost
were positive, with family labor cost and utility costs being highly significant. On the other
hand, the coefficient of veterinary cost was negative and highly significant. The technical
inefficiency effect model revealed that factors such as education, farm experience, training and
veterinary service had negative coefficients, indicating that they help in reducing the technical
inefficiency of dairy farmers. In terms of the challenges faced by farmers, the high feed cost,
lack of capital and lack of marketing facilities were identified as the top three concerns. To
address these challenges and enhance dairy production, it is recommended to provide subsidies
for purchasing inputs like better breeds of milking cows, cultivating green fodder, buying
concentrated feed etc. Also provide training facilities about dairy modern farming, adequate
veterinary services and offer accessible credit. This study will provide an important insight for
the concerned authority and help to boost dairy productio
