SABA, MAQSURUN NAHAR
During Rabi season, a field experiment was conducted at Sher-e-Bangla Agricultural
University, Dhaka from December 2021 to April 2022 to study the manual, chemical,
cultural, and integrated weed managements in soybean (Glycine max L.). The experiment
was laid out in randomized complete block design (RCBD) with twelve weed
management treatments such as no weeding (Control), two hand weeding (15 and 30
DAS), pre-emergence herbicide (Herbilin 33% EC @ 400 ml ha
-1
), post-emergence
herbicide, (Irish @ 1200 ml ha
-1
), pre + post-emergence herbicide, pre-emergence + 1
hand weeding {40 days after sowing (DAS)}, Post-emergence + 1 hand weeding (40
DAS), pre + post-emergence + 1 hand weeding (40 DAS), straw mulching, intercrop with
red amaranth (Amaranthus dubius), intercrop with maize (Zea mays), and weed-free. The
experimental result showed among seven different weed species found, Cyperus rotundus
was the most prevalent weed, with the highest weed density (128.67 and 123 m
) and
relative weed emergence (38.79 and 43.16 %) in the weedy check plot at 60 and 90 DAS,
followed by Echinochloa colona and Cynodon dactylon. In comparison, the dominance
of Heliotropium indicum and Alternanthera philoxeroides was the lowest among all weed
species in the weedy check plot at 60 and 90 DAS. In case of different weed management
treatments, the treatment Pre + Post-emergence + 1 hand weeding (40 DAS) showed the
highest pod length (4.16 cm) and seeds pod
-1
(3.89), while the weed free treatment
resulted with the highest 1000 seed weight (111.00 g), seed yield (1.86 t ha
), stover
yield (2.16 t ha
-1
), biological yield (4.03 t ha
-1
), harvest index (46.35 %). However, the
highest benefit-cost ratio (2.85) was obtained under post-emergence herbicide (Irish @
1200 ml ha
-1
) treatment. Therefore, applying post-emergence herbicide (Irish @ 1200 ml
ha
-1
) will be the best weed management practice for profitable soybean cultivation.

KADER, KAMILIYA
A field experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka
during the period from March to June 2021 in Kharif I season, to study the response
of blackgram varieties and different plant spacing. The experiment consisted of two
factors, and followed split plot design with three replications. Factor A:Blackgram
varieties (3)viz:V
1
-BARI Mash 2, V
2
-BARI Mash 3, V
-BARI Mash 4 and Factor B:
Different plant spacing (4) viz: S
1
= Broadcasting, S
2
3
= 15 cm × 10 cm, S
= 20 cm ×
20 cm, and S
= 30 cm × 15 cm. Experimental results revealed that different varieties
and plant spacing significantly influenced the yield and yield contributing parameters
of blackgram. In case of different blackgram varieties the maximum seed yield (1.49t
ha-

) was recorded from BARI Mash-3 (V
) was obtained from V

3
treatment and lowest seed yield (0.96 t ha
treatment (BARI Mash-2).The highest yield with BARI
Mash-3 (V
2
) was attributed due to the highest pods plant
-1
(6.52), pod length(5.22
cm), seeds pod
-1
(7.78), 1000-seed weight(42.76 g), biological yield (3.25 t ha
) and
harvest index (45.53 %).However in case of different plant spacing the seed yield
ranges between (0.92 -1.46 t ha
-1
). The highest seed yield (1.46 t ha
-1
) was recorded in
S
4
(30 cm × 15 cm) treatment which was achieved with maximum pods plant
(6.67),
pod length(5.36 cm), seeds pod
-1
(7.40) and 1000-seed weight(44.11 g).In case of
combination, cultivation of BARI Mash-3 (V
) along with 30 cm × 15 cm spacing
(S
4
2
) affected plant growth and yield-contributing characteristics, leading to the
maximum seed yield (1.80 t ha
-1
) compared to other treatment combinations.
Therefore, it is suggested that cultivation of BARI Mash-3 along with 30 cm × 15 cm
spacing (V
2
S
) could be as optimum in crop management for maximum yield harvest
in blackgram.

2021-01-01T00:00:00ZGROWTH AND YIELD OF MUSTARD AS AFFECTED BY VERMICOMPOST WITH DIFFERENT LEVELS OF FERTILIZERALI, MD RIPONhttp://localhost:8080/handle/123456789/49062023-05-23T04:58:13Z2021-01-01T00:00:00ZGROWTH AND YIELD OF MUSTARD AS AFFECTED BY VERMICOMPOST WITH DIFFERENT LEVELS OF FERTILIZER
ALI, MD RIPON
The experiment was conducted at the Agronomy farm of Sher-e-Bangla Agricultural
University, Bangladesh to find out the growth and yield of mustard as affected by
vermicompost with different levels of fertilizer during the period from November
2021 to March 2022. Two factors experiment was laid out in Split Plot Design with
three replications. Three mustard varieties viz. V
1
ii
(BARI sarisha-14), V
2
(BARI
sarisha-16) and V
3
(BARI sarisha-18) in association with four treatments of inorganic
fertilizers with or without vermicompost viz. control treatment T
0
(RDF), T
1
(RDF +
vermicompost 2.5 t ha
-1
), T
2
(75% RDF + vermicompost 2.5 t ha
-1
) and T
3
(50% RDF
+ vermicompost 2.5 t ha
-1
) were considered for the present study. Among three
varieties, V
3
(BARI sarisha-18) showed best performance for most of the parameters
and gave the highest shoot fresh weight plant
-1
, shoot dry weight plant
, SPAD value,
siliqua length, number siliqua plant
-1
, 1000-seed weight, seed yield, stover yield and
harvest index compared to V
1
(BARI sarisha-14) and V
2
(BARI sarisha-16).
However, among the different treatments applied to mustard, T
1
(RDF +
vermicompost 2.5 t ha
-1
) showed best results on different growth yield contributing
parameters and yield of mustard and gave the highest plant height, number of leaves
plant
-1
, shoot fresh weight plant
-1
, shoot dry weight plant
-1
, SPAD value, siliqua
length, number of siliqua plant
-1
, number of seeds siliqua
-1
, 1000-seed weight, seed
yield, stover yield and harvest index compared to other treatments. Regarding
treatment combination of variety and inorganic fertilizer with vermicompost, V
3
showed the best performance on different growth, yield and yield contributing
parameters in comparison to other treatment combinations. The maximum shoot fresh
weight plant
-1
(354.30 g), shoot dry weight plant
-1
(39.61 g), siliqua length (8.39 cm),
number of siliqua plant
-1
(154.30), 1000-seed weight (4.55 g), seed yield (2480.00 kg
ha
-1
), stover yield (2813.00 kg ha
-1
) and harvest index (46.80%) were obtained from
the treatment combination of V
3
T
1
whereas the lowest was from the treatment
combination of V
1
T
3
. So, it can be concluded that the application of (RDF +
vermicompost 2.5 t ha
-1
) to the variety BARI sarisha-18 can be considered to achieve
higher mustard yield.

2021-01-01T00:00:00ZGROWTH AND YIELD PERFORMANCE OF CHICKPEA THROUGH FOLIAR APPLICATION OF ZINC AND BORONSARKER, SHABIHAhttp://localhost:8080/handle/123456789/49052023-05-23T04:56:48Z2021-01-01T00:00:00ZGROWTH AND YIELD PERFORMANCE OF CHICKPEA THROUGH FOLIAR APPLICATION OF ZINC AND BORON
SARKER, SHABIHA
A field experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka
during the period from November 2020 to April 2021 in Rabi season, to study the
growth and yield performance of chickpea through foliar application of zinc (Zn) and
boron (B). The experiment consisted of two factors. Factor A. Different
concentrations of
Zn application: Zn
0
= Control (Water spray), Zn
1
= Basal application
of Zn, Zn
2
= 0.5 % foliar application at pre-flowering stage, Zn
3
= 1 % foliar
application at pre-flowering stage and Factor B. Different levels of B application: B
0
=
Control (Water spray), B
1
= Basal application of B, B
2
= 0.5 % foliar application at preflowering
stage and B
3
= 1 % foliar application at pre-flowering stage.
Experimental
result showed that foliar application of Zn and B were effective method for boost up
of yield in chickpea compared to soil application and control treatment. In the case of
different Zn levels, the lowest seed yield (1.02 t ha
ii
-1
) was
recorded in the control
treatment (Zn
0
). The highest number of pods plant
-1
(27.79),
seeds pod
(2.97), 1000seed
weight
(109.06 g) and seed yield (1.75 t ha
-1
) were
recorded in Zn
3
(1 % foliar
application at pre-flowering stage) treatment. In the case of
different B treatments, the
seed yield ranges between (1.19 -1.60 t ha
-1
-1
). The highest
seed yield (1.60 t ha
) was
recorded in B
3
(1 % foliar application at pre-flowering stage)
treatment. Both Zn and B
@ 1% solution sprayed at the pre-flowering stage
(Zn
3
B
3
) effected chickpea plant
growth and yield contributing characteristics, leading
to the maximum seed yield (2.01
t ha
-1
) than compared to other treatment combinations. Therefore, it could be suggested
that application of Zn (1.0 %) and B (1.0 %) by foliar spray at pre-flowering stage is
beneficial for better yield and quality production of chickpea crop.
