GENETICS AND PLANT BREEDINGThe experiment was conducted in the experimental area of Sher-e-Bangla Agricultural
University, Sher-e-Bangla Nagar, Dhaka during the time period of March to June 2022 to find
out the character association of 32 sesame genotypes. Mean performance, variability,
correlation matrix, path analysis and genetic diversity analysis on different yield contributing
characters and yield of sesame genotypes was estimated. The longest plant (127.87 cm) was
found in the genotype of G-3, whereas the shortest plant (93.29 cm) from the genotype of G-1.
The highest yield/plant (307.67 g) was found in the genotype of G-27, whereas the lowest
yield/plant (83.20 g) was observed from the genotype of G-10. Phenotypic coefficient of
variation was higher than the genotypic coefficient of variation for all the yield contributing
traits. In correlation study, significant positive association was recorded for yield/plant of
sesame genotypes with number of branches/plant (-0.049), number of capsules/plant (0.879),
length of capsule (0.355) and number of seeds/capsule (0.554). Path analysis revealed that days
to first flowering had negative direct effect (-0.326) on yield/plant. Number of capsules/plant
had positive direct effect (0.859) on yield/plant. Number of branches per plant had negative
direct effect (-0.077) on yield/plant. Number of seeds/capsule had positive direct effect (0.290)
on yield/plant. Weight of 1000 seeds had positive direct effect (0.267) on yield/plant. In genetic
diversity, cluster I was the largest cluster comprising of 20 genotypes followed by cluster II
with 9 genotypes, cluster III belongs 2 genotypes and cluster IV have 1 genotypes of sesame.
Inter cluster distance was maximum (2.761) between clusters II and III, followed by clusters II
and I (11.165). In consideration of yield contributing characters and yield G-27 perform better
followed by G-24 and G-9

AGRICULTURAL EXTENSION & INFORMATION SYSTEMThis study aimed to analyze the extent of factors from rooftop gardening that affecting
nutritional contribution to the gardeners and determine the contribution of selected
characteristics of their livelihood to the improvement of nutritional status. The study
employed a quantitative approach, and data were collected through a survey of 102
rooftop gardeners by using a structured questionnaire in Dhaka city, whereas the
population of the thesis was 1938. The data were analyzed using descriptive statistics and
stepwise multiple regression analysis. The results showed that rooftop gardening has a
medium to high effect (81.37%) on the nutritional status of gardeners, and the area used
for gardening has the highest (45.70%) contribution to this effect. Moreover, gardeners'
level of education, rooftop garden size, training exposure, perceived value of rooftop
gardening, and knowledge on rooftop gardening also have significant contributions. The
findings reveal that the majority of rooftop gardeners are middle-aged (49.01%), have
education above the secondary level (88.24%), have a medium-sized family (58.82%),
had a medium-sized gardening area (69.60%). Most gardeners (55.88%) had moderate
training exposure and perceived rooftop gardening to have medium value (52.94%). The
majority (72.55%) had medium knowledge of rooftop gardening. Based on the findings,
this study recommends that urban policymakers and planners should promote and support
rooftop gardening as a sustainable urban agriculture practice. Also, there is a need for
more training and extension services to improve the knowledge and skills of gardeners.
Finally, the study recommends that future research should focus on the economic and
environmental benefits of rooftop gardening and its contribution to the resilience of urban
food systems

Agricultural University, Dhaka, during the period from November 2021 to April 2022 to
find out the integrated effect of planting density and different level of biofertilizer doses
on the growth and yield of onion. The experiment was laid out in two factorial RCBD with
3 (three) replications. Factor A (Different Planting Distances) viz. S

Rhizobium, Phosphobacter, Trichoderma & Lactic Acid Bacteria. Significant variation was
found in all parameters due to the effect of different plant density and different amount of
biofertilizer application. In case of plant density, the maximum yield (11.14 t ha
) was
recorded from the favorable plant spacing i.e. 30 x 15 cm (S

) due to higher number of bulb
obtained per hectare land followed by S

treatment. One the other hand, the minimum yield
(8.72 t ha
-1
) was recorded from the broader plant spacing i.e. 30 x 20 cm (S

) due to lower
number of plant obtained per hectare land. The highest bulb yield (12.08 t ha
) was
recorded from the plot where

was obtained from the plot where only the recommended
dose of NPK (F

) was applied. The maximum yield (13.54 t ha
-1
) was recorded in the plot
where optimum plant spacing of 30 x 15 cm was maintained with 4 kg ha
biofertilizer
(S

). The findings of the
present investigation clearly indicates that the integrated use of optimum planting distance
and optimum level of biofertilizers for growing onion bulb is a viable option for improved
cultivation

AGRICULTURAL ECONOMICSThe study was conducted to identify the farmers’ current adaptation strategies to drought and
their determinants in northwestern parts of Bangladesh. The locale of the study was Tanore and
Nachole Upazila under Rajshahi and Chapainawabgonj districts in Bangladesh. A total of 150
farmers were selected through simple random sampling. Face-to-face interviews were
performed to gather data. The descriptive statistics and econometric model (Poisson Regression
Model) were applied to achieve the objectives of the study. The number of strategies
adoption constituted the dependent variable, and the selected ten farmer characteristics were
regarded as the independent variables. Statistical analysis shows that gender, education,
agricultural training received and agriculture related credit received had positive and significant
relationship with the adoption of adaptation strategies in drought. Credit was found as the most
significant positive factor on adopting a set of adaptation strategies, holding the co-efficient of
0.28. Some barriers to adoption were mentioned by farmers such as; lack of irrigation water,
lack of knowledge concerning appropriate adaptation, low credit facilities, and lack of adequate
extension services. Therefore, provision of necessary measures (re-excavation of canal,
installation of more deep tube-wells, motivating farmers to adopt drought tolerant varieties,
affordable access to credit, community-based education and training programs) by the
concerned authorities are preferable for improvement of the northwestern farmers’ adaptation
status
APPLYING BIOCHAR AND DIFFERENT FORM OF NITROGEN: BE A GOOD AGRICULTURAL PRACTICE FOR BETTER YIELD AND PROCESSING QUALITY OF POTATO
Get PDFAbstract
Purpose: Produced tubers with inferior quality are the main bottleneck for
exporting surplus amount of potato to the importing countries. Applying nitrogen
as prilled and super granule urea along with biochar may improve the yield and
processing quality of potato. To generalize a partial solution, the study was
conducted to find out the efficiencies of N forms and biochar towards the
improvement of the processing quality of potato for export.
Research Method: The experiment comprised two factors. Factor A: Nitrogen
fonn (2): Prilled Urea (Up) and Urea Super Granule (US), and Factor B: Biochar
level (6): BO-Control, 81- 2 tlha, B2- 4 tlha, B3- 6 t/ha, B4-8 tlha, and 85- 10
t/ha. The experiment was laid out in a split-plot design with three replications.
Results: Nitrogen form andlor biochar levels had shown significant influence on
most of then parameters. The maximum tuber yield of potato (37.9 t ha-l) was
observed from UsB5 which was statistically similar to UsB4. The maximum dry
matter content of tuber (21.8 %) and specific gravity of potato (1.098 g/cc) were
observed from UsB4. So, it may be concluded that the application of urea super
granule (US) plus biochar B4 (8 t/ha) was found best combination for maintaining
optimum yield and better processing quality of potato.
Findings: Application of biochar improved the soil organic carbon status (data not
shown) and exhibited better potato yield and qualities. Urea super granules (USG)
are much economic and environmental friendly

ANIMAL NUTRITIONAntibiotic growth promoter alternatives are urgently needed in the poultry industry to
maintain or improve poultry health and performance. Bacteriophage (BP) therapy
mainly utilizes lytic phage to kill their respective bacterial hosts and exhibit no activity
against animal and plant cells. They can be considered novel alternative solution to
combating the emergence of antibiotic resistance in poultry. A total of 600-day-old mix
broiler chicks (Hubbard Classic Efficiency Plus) with the initial body weight of
41.9±1.0 g were reared for 35-days experimental period. Birds were randomly allotted
into 1 of 5 treatments according to a Completely Randomized Design (CRD). Dietary
treatments consist T

(P <0.05) (0.5g BP/kg)
group (1.49) compared to the T

Control group
(1.58). The group T

and differ significantly (P<0.05) from other groups however not
significantly different (P = 0766.) from T
4.
The weight of the spleen in the control group
T

is the highest and is differ significantly (P<0.05) with other groups. Similarly, the
bursa of fabricus' weight is the highest in T

group and differs significantly (P<0.05)
with other groups. Among the three-bacteriophage dietary treatment group T
1
showed
better body weights and FCR than group T
2
and T

. In conclusion, dietary
supplementation of 0.5 g/kg BP reduced FCR and increased body weight with inhibiting
of pathogens. Therefore, the research recommended inclusion of 0.5 g BP/kg of feed as
an alternative to antibiotic growth promoters in broiler diets
