SEMESTER: JANUARY-JUNE, 2021High temperature exerts adverse effect on the growth, physiology, developmental
processes and yield of wheat. In Bangladesh the winter is very short. So, timely sowing
of wheat seeds can be helpful. The experiment was laid out in a Completely Randomized
Design with three replications at the net house of the Department of Agricultural Botany,
Sher-e-Bangla Agricultural University, Dhaka during the period from November 2019 to
March 2020 to find out the effect of high temperature stress on growth, physiology and

AGRONOMYThe experiment was conducted at the Central Laboratory of Sher-e-Bangla
Agricultural University, Dhaka to find out the effect of pre-storage seed treatment on
storability of transplanted aman rice seed during the period from January to October,
2020. Two T. aman rice varieties viz. BRRI dhan87 (V
1
) and
BR11 (V
2
) and five seed
treatments viz. control treatment; no seed treatment (T
0
), ascorbic acid @ 0.5 g/kg
seeds (T
1
), aspirin @ 0.1 g/kg seeds (T
2
), bleaching powder @ 2 g/kg seeds (T
3
) and
red chili powder @ 2 g/kg seeds (T
4
) were used in this experiment. The experiment
was carried out following Randomized Complete Block design with four replications.
Data were collected after treatment and at storage (initial, 236 days after storage and
271 days after storage) on germination percentage, germination speed index, seedling
vigour index, germination rate, mean daily germination, mean germination time, peak
value, germination value, shoot length, root length, total length, moisture content
percentage and viability percentage. The result revealed that BRRI dhan87 (V
1
)
finally (at 271 days after storage) showed the highest germination percentage
(81.20%), germination speed index (8.26), seedling vigour index (17.95), germination
rate (10.74), mean daily germination (5.35), mean germination time (27.31), peak
value (16.93), germination value (93.94), shoot length (13.59 cm) and viability
percentage (84.15%) compared to the variety
BR11 (V
2
). The maximum storage
duration (at 271 days after storage), seeds treated with Bleaching powder @ 2 g/kg
seeds (T
3
) performed better in maintaining significantly higher germination (71.75%),
germination speed index (7.66), peak value (15.60), germination value (83.60) and
viability percentage (76.00%) followed by aspirin @ 0.1 g/kg seeds (T
2
). These
treatments also showed better performance at 236 days after storage whereas control
treatment T
0
showed least performance. At 271 days after storage, interaction effect of
BRRI dhan87 and bleaching powder @ 2 g/kg seeds (V
1
T
3
) gave the highest
germination percentage (86.50%), germination speed index (8.85), mean germination
time (29.89), peak value (18.45), germination value (115.85) and viability percentage
(89.00%). V

also gave better performance at 236 days after storage compared to
other treatment combinations whereas V

SOIL SCIENCEThis experiment was done to know the effect of different doses and time of
application of mustard oil cake on the growth and yield contributing characteristics of
rice. The experiment was carried out at the Soil Science Farm at Sher-e-Bangla
Agricultural University, Dhaka during the period of November, 2019 to May 2020 to
study the effect of different rates and dates of mustard oil cake application on growth
and yield of rice (BRRI dhan67). The experiment was laid out on Randomized
Completely Block Design (RCBD) with three replications. There were four mustard
oil cake (MOC) fertilizer levels viz., M

GENETICS AND PLANT BREEDING
SEMESTER: JULY-DECEMBER, 2021The experiment was carried out using ten genotypes of bottle gourd at the farm of Shere-
Bangla Agricultural University, Dhaka to determine the genetic variability and to
select the best performing genotypes for yield and its contributing traits during October
2020 to March 2021. The experiment was carried out in randomized complete block
design with three replications. Analysis of variance revealed significant variations was
exist among all the genotypes for the selected traits. The estimated variance components
indicated environmental factors also contributed for the expression of the traits as the
phenotypic co-efficient variation was higher than the genotypic counterparts. However,
high heritability coupled with high genetic advance as percentage of mean was found
in number of fruits per plant, fruit length, fruit diameter, fruit pedicel length, individual
fruit weight, number of seeds per fruit, 100 seed weight, seed length, seed breadth and
fruit yield per plant, hence inheritance of these traits was controlled by the additive gene
actions whereas rest of the traits was governed by non-additive gene actions.
Correlation study revealed that fruit yield per plant had a significant positive correlation
with leaf breadth (cm), fruit diameter (cm), 100 seed weight (g) and individual fruit
weight (kg) at the both genotypic and phenotypic levels. Moreover, path analysis
revealed that days to 1
st
female flowering, leaf length, no. of male flowers, fruit length
(cm), fruit diameter (cm), no. of fruits per plant, 100 seed weight (g) and individual
fruit weight (g) showed positive direct effect on fruit yield per plant (kg) indicating that
direct selection based on these traits may be helpful in evolving high yielding varieties
of bottle gourd. Among the ten genotypes, G4 followed by G5, G7 and G10 showed the
highest individual fruit weight while the highest fruit diameter was found in genotype
G4 followed by G5, G7 and G8. Based on the individual fruit weight and fruit diameter
that have a direct influence on generating the highest yield production; genotypes G4,
G5, G7, G8 and G10 can be selected for developing the superior bottle gourd variety in
future breeding programme

(180.67 cm), number of seed per head (645.5), number of leaves per plant (23.33),
leaf area (65.33 cm), length of leaf (23.88 cm), leaf width (19.88 cm), weight of total

SEMESTER: JANUARY-JUNE, 2021The experiment was conducted at the research field of the Department of Agricultural
Botany, Sher-e Bangla Agricultural University, Dhaka during the period from
November 2019 to February 2020 to observe the effect of high doses urea on three
different cultivars of mustard (BARI sarisha 11, BARI sarisha 16 and BARI sarisha
17). Three different levels of urea fertilizer was used such as T1 (250 kg/ha), T2 (312.50
kg/ha) and (375 kg/ha). The experiment was laid out under two factors Randomized
Complete Block Design (RCBD) with 3 replications. Under T1, the tallest plant height
at harvest was 131.86 cm (BARI recommended dose). Lowest plant height was
observed 100.59 cm under treatment T3. Overdoes of urea may cause plant height to
decrease. The highest number of leaves was recorded 38.43 under T3. So, we can see
that plant became bushier when an excess amount of urea was applied. Seed per siliqua
was also affected by different quantities of urea. Under the recommended dose, the
highest number of seed per siliqua (21.44) was recorded. Higher urea doses (T3) most
likely had a negative impact on seed output. In the case of seed dry weight and pod
length, there was no significant association. As a result, the total influence on yield
components was negligible. The physiological indicators were significantly affected by
varying levels of urea administration. Significant differences were seen between the
SPAD reading and the Leaf porometer reading. T3 obtained the highest SPAD
measurement (49.88) and T1 recorded the highest Leaf porometer reading (336.95).
Results indicate that Overdose of urea had detrimental effect on yield of mustard plant
though vegetative growth was higher in case of higher dose. Number of seed per siliqua
was found highest (21.44) under treatment T1 (250kg/ha)
