:
Confidor 70WG (imidacloprid) @3g/kg of seed, T
2
: Bioneemplus 1EC (azadirachtin)
@1.0 ml/L of water, T
3
: Neem seed kernel extract (azadirachtin) @50 g/L of water, T
4
:
Tracer 45 SC (spinosad) @0.4 ml/L of water and T
5
: untreated control, for the
management of aphid and tobacco cutworm of mustard with three replications for each
treatment. Data on different parameters were recorded and significant variation was
observed among different treatment. Experimental result showed that at early, mid and
late stage of flowering and fruiting the highest number of aphid and cutworm was
observed in T
5
treatment while the lowest number of aphid and cutworm was observed in
T
4
treatment. In case of aphid at flowering fruiting stage the maximum number of healthy
plant m
-2
(28 and 24.67) and higher infestation reduction percentage (76.92 and 72.78 %)
was observed in T
4
treatment. In the case of tobacco cutworm at the flowering and
fruiting stages, the highest number of healthy plants per square meter (29.33 and 28.00)
and the highest infestation reduction percentage (87.64and 76.92 %) was found in the T
4
treatment. In case of growth, yield contributing characters and yield of mustard, among
different treatments the maximum plant height (106.35 cm), number branches plant
(16.02), siliqua plant

) was obtained from T
4
treatment
which gave (84.38 %) more yield comparable to control treatment. Based on the
investigation of the above results, it may be concluded that among seed treating chemical
and few botanicals for controlling mustard aphid and tobacco cutworm, spraying Tracer
45 SC @0.4 ml/L of water at 10-day intervals was the most effective among the
management practices for controlling mustard aphid and tobacco cutworm

AGRICULTURAL EXTENSION & INFORMATION SYSTEMThe purposes of the study were to assess the adverse effect of traditional brickfield on
agriculture; to compare item-wise effects of traditional brickfields; to describe some
selected characteristics of the farmers and to explore the relationships between each of
the selected characteristics of the respondents to their perceived effects of traditional
brickfields on agriculture. The study was undertaken purposively in Sadarpur upazila
under Faridpur district. Validated and well-structured interview schedule was used to
collect data from 96 farmers during 15 November to 14 December, 2022. The highest
proportion (61.5%) of the farmers perceived medium effects as compare to 3.1 percent
perceived low effects and 35.4 percent perceived high effects of traditional brickfield
on agriculture. On the basis of SEI, it was observed that “reducing top fertile soil”
ranked first followed by “reducing crop production area”, “reducing biodiversity”,
“reducing crop production”, “reducing local forest and trees area”, and “reducing
livestock production”, “reducing fisheries production” and “reducing poultry
production” were the least effects of traditional brickfield on agriculture. Pearson’s
Product Moment Correlation revealed that education, farm size, annual family income
and agricultural farming experience of the farmers had positive significant relationship
with their perceived adverse effects of traditional brickfield on agriculture. Based on
the findings, it is recommended that traditional brickfield should be stopped or transfer
to eco-friendly brick manufacturing to reduce the adverse effects of traditional
brickfield on agriculture

AGRICULTURAL CHEMISTRYAn experiment was carried out at Sher-e-Bangla Agricultural University (SAU), Sher-eBangla
Nagar, Dhaka-1207 to study the effects of organic and inorganic fertilizers on
growth, yield, and nutrients content of capsicum (Capsicum annuum L.) during the period
from November 2021 to March 2022. The experiment considered 8 treatments viz. T
0
(control), T
1
(Recommended doses; RD of inorganic fertilizer), T
2
(Vermicompost - 3.5 t

), T
4
(50% vermicompost + 50% inorganic fertilizer of
RD), T
5
(25% vermicompost + 75% inorganic fertilizer of RD), T
6
(50% poultry manure +
50% inorganic fertilizer of RD) and T
7
(25% poultry manure + 75% inorganic fertilizer of
RD). The treatment T
5
(25% vermicompost + 75% inorganic fertilizer of RD) exhibited the
highest plant height (51.93 cm) but the treatment T

(52.07 cm), branches plant
(8.71), fruit length (89.93 mm), fruit diameter
( 67.27 mm), individual fruit weight (94.85 g), number of fruits plot
-1
(40.67), yield plot
(3859.00 g) and yield (19.30 t ha
-1
) whereas control treatment showed least performance.
Regarding the nutrient content of capsicum, N content differed significantly and the
treatment T
7
(25% poultry manure + 75% inorganic fertilizer of RD) showed the maximum
N content (1.73%) whereas T
0
(control) treatment showed the lowest result (0.57%). P and
K contents of fruit showed non-significant variation among the treatments. So, it can be
concluded that the treatment T
4
(50% vermicompost + 50% inorganic fertilizer of RD)
treatment was very much promising for higher capsicum production (ASTHA F1) followed
by T
5
(25% vermicompost + 75% inorganic fertilizer of RD). Treatment of 50%
vermicompost + 50% inorganic fertilizer of RD (T
4
) can be recommended at farmers level
to achieve higher capsicum production

AGRIBUSINESS AND MARKETINGPotato is one of the most important cash crops in Bangladesh, and the district of Panchagarh
is one of the major potato producing areas in the country. The objective of this study was to
analyze the value chain of potato in some selected areas of Panchagarh district, including the
profitability, value addition, marketing cost, and net marketing margin of different actors in
the chain. To achieve these objectives, a structured questionnaire was used to interview 25
farmers, 65 middlemen, and 5 cold storage owners from February to April 2023. The data
collected were analyzed using profitability analysis, regression analysis, and moving average
method. The findings of this study revealed that the sales price of potato varied significantly
between different actors in the value chain. The highest sales price per 100kg of potato was
received by the retailer at Tk.2225.00, while the lowest sales price was received by the farmer
at Tk.1625.55. The value addition by different actors in the chain varied from 9.25% to
25.70%, with the wholesaler having the highest value addition. The marketing cost of the
value chain actors varied from 4.51% to 45.90%, with the wholesaler incurring the highest
marketing cost. The net marketing margin of different actors in the chain also varied
significantly, ranging from 6.65% to 47.45%, with the retailer having the highest net
marketing margin. In addition, the seasonal price fluctuation analysis showed that the price of
potato was significantly lower during the peak harvesting period, while it was much higher
before the planting period. Moreover, the study found that proper credit facilities should be
ensured for the value chain actors, as this was mentioned by the highest number of
respondents. The study provides valuable insights into the value chain of potato in
Panchagarh district, and highlights the need for policies and interventions to improve the
profitability and efficiency of the value chain

AGRICULTURAL EXTENSION & INFORMATION SYSTEMThe study was aimed to examine the Farmers’ opinion about climate change effect
in haor area of Bangladesh and estimate the level of contribution of the selected
characteristics of the farmers to the effect of climate change on agriculture. The
study used quantitative and qualitative methods based on data collection. The locale
of the study was conducted in Mohanganj upazila under Netrokona district and data
were collected from 80 farmers in March, 2023. Descriptive statistics, multiple
regressions, were used for data analysis. In case of study, 50.0 percent of the
farmers encountered high effect, 33.75 percent faced medium effect and 16.25
percent of the farmers encountered low effect of climate change in haor area of
Bangladesh. Among the variables age, family size, annual family income,
educational qualification, access to ICTs, perception on climate change, attitude
towards adverse effect climate change and Farmer’s opinion about Climate Change
effect in Haor Area of Bangladesh had significant contribution to the effect of
climate change on the farmers in haor area of Bangladesh. It is concluded that
climate change may play an important role in decreasing the yield of agricultural
production and increasing the number of adopted new varieties of agricultural crops
by the farmers. It is recommended that the Bangladesh government should take
initiative such as ensuring adult education, giving more knowledge to ICTs,
adopting resistant varieties for reducing effect of climate change on farmers in haor
areas of Bangladesh for a sustainable agricultural developmen

AGRICULTURAL ECONOMICSIntegrated Pest Management (IPM) practices are one of the most important technologies
which are available in Bangladesh agriculture now-a-days. The present study was undertaken
mainly to identify the determinants affecting the adoption of IPM practices by the tomato
producers. For achieving the objectives, the study was conducted on 120 tomato farmers of
Palash upazila (60) and Shibpur upazila (60) of Narsingdi district, of which 60 were
considered as IPM users and 60 as IPM non-users. Descriptive statistics and binary logistic
regression were used to achieve the objectives of the study. Majority of the tomato producers
who produced tomato through IPM practices constituted middle aged farmers with middle
family size and low farming experience and having small farm size, where most of the tomato
producers who did not use IPM had medium farming experience with marginal farm holding
and most of them were old aged with medium family size. The determinants that significantly
affects adoption decision of IPM were age, education, societal membership, use of hired
labor, livestock, training on IPM and distance to local market. Among these variables,
training on IPM was the most influencing factor. Therefore, age and distance to local market
have negative significance on adoption. Lack of credit, expensive inputs, unavailability of
organic fertilizer, inexperienced trainers were some of the constraints faced by the tomato
producers for both non-IPM and IPM practices. Government should give more emphasis on
training and raising awareness on IPM to influence in using IPM
