Effects of Nitrogen and Potassium on Yield and Quality Of Potato (Solanum Tuberosum L.) Cultivars
No full textEffects of nitrogen (N) and potassium (K) fertilization rates on the yield and quality of two potato cultivars, Asterix and Courage were conducted. The treatment combination of N2K2 (N2: 140 kg ha−1 and K2: 152 kg ha−1) had the highest total yield (31.38 and 22.51 t ha-1), marketable tuber yield (29.08 and 20.49 t ha-1) and chips potato yield (36.63 and 36.96%) of the 18 treatment combinations for Asterix and Courage cultivar, respectively. The treatment combination of N2K2 had also the highest specific gravity (1.07 and 1.17 gcm-3), dry matter (22.65 and 22.77%), firmness (45.13 and 42.92 N), and lowest total soluble solid (4.30 and 4.23 oBrix) in both the cultivars, whereas the colour of the chips revealed the least crispness (0.15 and 0.17 N). In order to enhance potato processing quality without reducing production, a lower N and higher K treatment combination may be employed. Bangladesh J. Bot. 52(2): 267-275, 2023 (June

AGRICULTURAL EXTENSION & INFORMATION SYSTEMThe purpose of this study was to determine the extent of knowledge, attitude and practice of
the farmers regarding safe vegetable production, explore the relationships between six
selected characteristics of the farmers with their knowledge, attitude and practices and the
inter-correlation among knowledge, attitude and practices regarding safe vegetable
production. Data were collected from 90 farmers from four unions of Dohar and Nawabganj
upazila under Dhaka district by using an interview schedule. Data were collected from
October 25, 2022 to December 23, 2022. Descriptive statistics such as mean, standard
deviation, range and percentage were used to describe the variables under consideration.
Pearson Product Moment Correlation Coefficient was used to explore the relationship.
Majorit y (61.1 %) of the farmers possessed ‘medium knowledge’ while 15.6 % and 23.3 %
of the farmers possessed ‘low’ and ‘high knowledge’ respect ively in safe vegetable
production. The majority (71.1 %) of the farmers’ had favorable attitude towards safe
vegetable production compared to (22.2 %) having unfavorable and only (6.7 %) had neutral
attitude. Majorit y (58.9 %) of the farmers had ‘medium practice’ while (16.7 %) far mers had
‘high practice’ and (24.4 %) farmers had ‘low practice’ of safe vegetable production.
Commercializat ion and extension contact had significant posit ive relat ionship with farmers’
knowledge, attitude and practices on safe vegetable production and percent safe vegetable
production area had negat ive significant relat ionship wit h farmers’ practices on safe
vegetable production. Age, education and BCR from vegetable production had no significant
relationship with their knowledge, attitude and practices in safe vegetable production.
According to Standardized Problem Faced Index (SPFI), ‘low price against production cost’,
was ranked first (SPFI 78.88 %) and ‘high production cost’ ranked the last (SPFI 45.55 %)
regarding safe vegetable production. It is therefore, recommended that concerned authorities
should give attention to solve the problems faced by the farmers by providing training and
loan at cultivation season and making more contact with farmers, so that they can get more
knowledge, form favorable attitude and more use of improved practices of safe vegetable
production

PLANT PATHOLOGYAn experiment was conducted for detection, identification and measurement of
diseases of selected tropical sugarbeet and beetroot under natural field conditions at
Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from
December 2020 to April 2021.Three different varieties of sugarbeet viz. KWS Allanya,
KWS Serenada, KWS Gregoria and three different varieties of beetroot viz. Rokto,
Beet King and Red Ball were used in this experiment. Sugarbeet varieties were
collected from Bangladesh Sugarcrop Research Institute, Ishurdi, Pabna and the
beetroot varieties were collected from Siddiqbazar, Dhaka, Bangladesh. The
experiment was laid out in a randomized complete block design with three
replications. The disease incidence and severity were recorded under natural condition
at different Days after sowing (DAS). Yield and yield contributing characters of
sugarbeet and beetroot plant were also recorded as the part of this study. Three fungal
diseases were found in sugarbeet field namely Sclerotium root rot caused by
Sclerotium roilfsii, Fusarium yellows caused by Fusarium oxysporum and Cercospora
leaf spot caused by Cercospora beticola. However, two diseases were found in
beetroot field namely Alternaria leaf spot caused by Alternaria alternata and leaf
blight caused by Fusarium oxysporum. At 100 DAS the highest sclerotium root rot
disease incidence was recorded in KWS Serenada (32.37%). At 105 DAS, the highest
disease incidence of Fusarium yellows was recorded in KWS Gregoria (25.73%). At
105 DAS the highest disease incidence of Cercospora leaf spot was recorded in KWS
Allanya (29.43%). Plant height varied from 29.53 cm to 61.87 cm. Number of leaves
varied from 9.87 to 20.33. Whole plant weight varied from 1.50kg to1.73kg from the
selected three variety of sugarbeet. At 95 DAS, the disease incidence of Alternaria leaf
spot was counted where the highest disease incidence was recorded in Red Ball
(30.23%). At 100 DAS, the highest disease incidence of leaf blight of beetroot was
recorded in Beet King (21.57%). Plant height varied from 22.27 cm to 37.70 cm.
Number of leaves varied from 8.40 to 15.67. Whole plant weight varied from 0.57 kg
to 0.67 kg from the variety of beetroot. Depending on the disease incidence and
severity, the major diseases of inspected sugarbeet and beetroot plants were;
Sclerotium root rot, Fusarium yellows, Cercospora leaf spot, Alternaria leaf spot and
leaf blight

DEPARTMENT OF HORTICULTUREAn experiment was carried out at the Horticulture research field of Sher-e-Bangla
Agricultural University, Dhaka during the period from November 2020 to March 2021
to find out the yield and quality of different turnip varieties influenced by
vermicompost. The experiment was laid out in two factorial RCBD with 3 (three)
replications. Factor A (Three different turnip varieties) viz. V
1
= Purple Top White
Globe; V
2
= Pusa Chandrima; V
3
= Early Milan Red Top and Factor B (Four different
levels of vermicompost) viz. F
1
= 0 t/ha; F
2
= 2 t/ha VC doses, F
3
= 4 t/ha VC doses
and F
4
= 6 t/ha VC doses. Significant variation was found in all parameter due to the
effect of different turnip variety and different amount of vermicompost application. In
case of different variety, the maximum yield (17.84 t ha
-1
) was recorded from the Purple
Top White Globe (V
1
) as it is a high yielding variety. One the other hand, the lowest
root yield (11.02 t ha
-1
) was recorded from Pusa Chandrima (V
2
) which is a moderate
early variety. In case of different levels of vermicompost, results exposed that the
highest roots yield (17.22 t ha
-1
) was recorded from F
3
(4 t ha
-1
VC) which was
statistically different from all other treatments, where the lowest yield (10.75 t ha
) was
achieved from F
1
(0 t ha
-1
VC i.e. control). Finally, root yield as t ha
-1
was the output of
different varietal treatments applied as well as the effect of different level of
vermicompost (VC) doses. The maximum roots yield (21.24 t ha
-1
) was found from
V
1
F
3
(Purple Top White Globe with 4 t/ha VC doses) which was statistically different
from others. Again, the minimum roots yield (7.80 t ha
-1
) was observed from V
2
(Pusa
Chandrima with 0 t/ha VC doses i.e. Control) which was statistically similar with V
2
(Pusa Chandrima with 2 t/ha VC doses). The findings of the present investigation
clearly indicates that the use of Purple Top White Globe turnip variety and optimum
level of vermicompost for growing turnip root is a viable option for improved
cultivation
PHYSIOLOGICAL AND BIOCHEMICAL MECHANISMS OF MICRONUTRIENT MEDIATED SALT STRESS TOLERANCE IN SOYBEAN
Get PDFAbstract
Like other abiotic stresses, salinity also adversely affects the vital morphological,
physiological and biochemical mechanisms of plants and ultimately causes yield
reduction. This experiment was carried out to study the morphological,
physiological, biochemical, phenotypical and anatomical responses of soybean
(Glycine max L., cv. BINA Soybean 5) upon exposure to different levels of
salinity and to investigate the role of exogenous application of selenium (Se) and
boron (B) in mitigating salt stress. Plants were treated with 0, 150, 300 and 450
mM NaCI at 20 DAS and 35 DAS to stimulate salinity. Exogenous application of
Se (0.50 11MNa2Se04) and B (1 mM H3B03) was done individually (Se, B) and
combinedly (Se+B) at 20 DAS and continued at three days interval until pod
filling stage under normal and saline condition. Plants exhibited a reduction in
plant height, shoot fresh weight, shoot dry weight, root fresh weight, root dry
weight, number of branchesplant', number of flowers plant", leaf area, relative
water content and SPAD value under salinity in a dose-dependent manner, which
were observed for assessing the growth and physiological responses. However,
proline content and oxidative stress indicators such as MDA content and H202
content were increased with the increase of salinity. Consequently, it caused a
reduction in pod length, pod plant", seed pod', seed yield plant", stover yield and
biological yield. In responses to, 300 and 450 mM NaCI-induced salt stress, plant
death occurred after completing the vegetative stage. Phenotypical and anatomical
parameters showed a visible deleterious effect of different levels of salinity on
growth and number of stomata, respectively. On the contrary, exogenous
application of Se, Band Se+B reverted the negative effect of salinity. Though, the
combined application of Se+B showed a slight difference in result than Se or B
alone, the findings indicate that exogenous application of Se, Band Se+B
mitigated the adverse effects of salinity by up regulating physiological and
biochemical processes and by enhancing growth parameters.

MASTER OF SCIENCE IN ANIMAL BREEDING AND GENETICSThe aim of the study was designed to Evaluate the Productive and Reproductive
Performance of Non-Descript Buffaloes of Bhola District in Bangladesh. Data were
collected through interview of randomly selected 349 members of Bhola districts who
were involved in buffalo farming. The investigation revealed that majority of the buffalo
farmers were poor (46.47%) and non-poor (45.07%), the education level of the farmers
were below primary (70.48%), and up to primary (31.48%), age of the farmers were over
25 years old (72.27%), and among them about 96.36% farmers were male. The family
members of the buffalo farmers ware average 5.28. The mortality rate of buffalo calves
and buffalo, were 17.08% and 8.75% respectively. The average lactation period was
5.77±0.26 months, gestation period 285±0.70 days average milk production per day was
1.56±0.25 liter and total milk production in lactation period was 268.08±6.34 liters. The
reproductive parameters like age at first heat 37.2±0.25 months, age at first pregnancy
38.4±0.26 months, number of services per conception 1.77±0.26 number, duration
between estrus and insemination 10.09±0.70 hours, post-partum heat period 106.20±0.36
days, dry period 167.8±0.67 days, calving interval 660.8±0.97 days, Pregnancy rate
28.03±.02 % and age at puberty 455.33±.27 days respectively. All (100%) of the farmers
practice natural insemination technique, where 63.1% farmers have their own bull for
breeding. No farmer use record keeping system in the farm. There is a believe that buffalo
meat is not good for health that the reason consumer refuse to take buffalo. There is no
available market for buffalo meat. This study would help the policy makers to take
necessary strategies to improve the socio-economic status of buffalo farmers in this
region of Bangladesh

DEVELOPMENT AND POVERTY STUDIESThe adoption of modern technology is crucial for improving the beef cattle fattening
industry in Bangladesh. This study aimed to identify the knowledge, attitudes, and
practices of beef cattle farmers regarding various technological practices, such as
supplementary feeding, routine vaccination, housing of cattle, minerals
supplementation, cleaning of housing, detection and isolation of sick cattle, de-ticking
of cattle, and hoof trimming. The study analyzed the data obtained from 80 beef cattle
farmers using a structured questionnaire. The results of the study revealed that
supplementary feeding, routine vaccination, housing of cattle, de-ticking of cattle, and
hoof trimming are widely practiced by the farmers. However, minerals
supplementation, cleaning of housing, and detection and isolation of sick cattle are not
frequently practiced. The study also found that farmers mainly gained knowledge
from other farmers and NGOs, and radio/TV education played a minor role in
disseminating information about technological practices. The study concludes that
beef cattle farmers in Bangladesh have a positive attitude toward adopting modern
technology, but further extension services and training programs are required to
increase the adoption rate of less frequently used technological practices. The results
showed that while supplementary feeding (92.5%), routine vaccination (80%),
housing of cattle (73.75%), de-ticking of cattle (96.25%), and hoof trimming (95%)
were widely practiced, minerals supplementation (41.25%), cleaning of housing
(21.25%), and detection and isolation of sick cattle (35%) were less frequently
practiced. The study also found that farmers mainly gained knowledge from other
farmers (ranging from 30% to 56% depending on the practice) and NGOs (ranging
from 9% to 31%), and radio/TV education played a minor role (ranging from 1% to
28%). Technology adoption should be a strategic decision based on their specific
circumstances and goals. It's important to carefully evaluate each technology and its
potential impact on their farm before making any significant investments
MEASURING POVERTY USING MULTIDIMENSIONAL POVERTY INDEX: A CASE STUDY OF PUTIMARI UNION, NILPHAMARI

DEVELOPMENT AND POVERTY STUDIESThis study is designed to measure poverty from the multidimensional poverty index
perspective. As the targets under the first goal of SDGs: the end of poverty in all its forms
everywhere emphasize poverty reduction at different magnitudes by the year 2030, poverty
alleviation has become a key area to work on. The multidimensional poverty index (MPI)
approach can be the best measure of monitoring the target of the first goal of the SDG.
This study considered the Putimari union of Nilphamari district in Bangladesh because of
their high poverty level. The unidimensional measure of poverty, like the headcount index,
does not show the severity of poverty. To address this fact, this paper intends to measure a
multidimensional poverty index for measuring acute poverty. The quantitative research
approach has been adopted and this study have selected a total of 60 households as a
sample size. The questionnaire survey was used to collect household data which was
collected in the Putimari union of Nilphamari district. To construct MPI, 20 indicators have
been considered under five major dimensions as education, health, standard of living,
financial and political aspects. The household-based approach has been used and a
household is considered multi-dimensionally poor when it is found to be deprived in more
than or equal to one-third of total dimensions. The result found that 127 people and 33
households, or 57.21 percent of the population, are not categorized as multi-dimensionally
or severely poor (i.e., those with poverty scores between 0 and 20). Also, the vulnerable
group, which comprises 43 people from 11 households and may be at danger of becoming
poor in the future (i.e., those with poverty scores between 20 and 33). Based on the MPI
tool, 23.42% of the total population – 52 individuals from 16 households – are classified as
MPI poor
