A field experiment was conducted at the Agronomy research field, Sher-e-Bangla
Agricultural University, Dhaka from November 01, 2014 to April 30, 2015 to find out
the effect of 4 different vermicompost (Vm) levels viz., Vm

varieties viz., V

-BARI TPS-1, V

- BARI Alu-28 (Lady Rosetta), V
- BARI Alu-29
(Courage), V
- BARI Alu-25 (Asterix). The experiment was conducted in spilt plot
Design with 3 replications. The different levels of vermicompost had significant effect
on most of the growth, yield and quality contributing parameters of potato irrespective
of varieties. All parameters studied in this experiment were increased with the
increasing vermicompost levels except water percentage. The variety „BARI Alu-28‟
produced maximum yield (28.89 t ha
4
-1
) whereas, „BARI TPS-1‟ showed minimum
yield (22.95 t ha
-1
) irrespective of vermicompost levels and other growth, yield and
processing characters also influenced by the different varieties. The results also
revealed that the yield of potato varieties were increased with increasing
vermicompost levels. „BARI Alu-28‟ cultivated with vermicompost 6 t ha
performed
the best results and the same variety with 4 t ha
-1
also showed the statistically similar
results in terms of growth, most of the yield and quality parameters. Among the 16
treatment combination maximum tuber weight (57.18 g) was produced in V
and
the variety Lady Rosetta produced
highest yield (33.86 t ha
-1
), highest marketable
yield (28.78 t ha
-1
) and also produced maximum seed tuber (25.40 t ha
) when
cultivated with 6 t ha
-1
vermicompost. Incase of dry matter, reducing sugar and starch
content, Lady Rosetta showed the best performance compared to those other varieties
when 6 t ha
-1
vermicompost was applied.

KAES, IMRUL
An experiment was conducted at the Agronomy field laboratory, Sher-e-Bangla
Agricultural University, Dhaka, from November 2014 to April 2015 to evaluate the
different herbicidal efficacy on weed control and growth & yield of boro rice cv. BRRI
dhan50. The experiment comprised nine treatments viz. Acetachlor + Bensulfuran (Premix)
@
750
g
ha
-1
, Pyrazosulfuran-ethyl @ 150 g ha

, Bispyribac Sodium @ 150 g ha
,
Pretilachlor @ 1 L ha

, Pretilachlor+ Triasulfuran@ (1 L + 10 g) ha
-1
, Propyrisulfuran +
Propanil @ (0.5 L + 1 kg) ha
-1
, Propyrisulfuran + Propanil@ (0.38 L + 1.5 kg) ha
, Two
hand weeding (20 and 40 DAS) and Weedy check.The experiment was laid out in
randomized complete block design (RCBD) with three replications. Sixteen weed
species belonging to seven families were observed in the experimental field. Weed
population, weed dry weight and weed control efficiency were significantly influenced
by herbicidal treatments. The highest weed population and dry weight were observed in
unweededcontrol condition compared to other treatments. Application of
Propyrisulfuran + Propanil (0.38 L + 1.5 kg) ha
-1
showed the best performance to control
all kind of weeds found in the field and its residual activity remained upto 45 days.Yield
contributing characters and yield of BRRI dhan50 was significantly influenced by weed
control treatments. The highest number of effective tillers hill
-1
, grains panicle
, 1000grain
weight, grain yield, straw yield and harvest index were obtained from the
application of Propyrisulfuran + Propanil (0.38 L + 1.5 kg) ha
-1
. Weed control had
pronounced influence on yield (5.50 t ha
-1
) of BRRI dhan50 and 46.55% yield was lost
in unweeded control condition. It can be concluded that application of Propyrisulfuran +
Propanil (0.38 L + 1.5 kg) ha
-1
may be used for the best performance of BRRI dhan50.
However, in practical point of view the application of Propyrisulfuran+ Propanil (0.5 L
+ 1 kg) ha
-1
may consider for producing second highest yield of BRRI dhan50.

AKTER, MAHBUBA
A field experiment was conducted at the Research Field and Agronomy Laboratory of Shere-Bangla
Agricultural University, Dhaka 1207 during the period from November, 2014 to
March, 2015 to evaluate the effect of nitrogen levels on growth, yield and seed quality of
wheat. The experiment comprised of five nitrogen levels viz. (i) N
= Control (no nitrogen),
(ii) N
1
= 25% less nitrogen from the recommended dose, (iii) N
2
0
= Recommended dose of
nitrogen, (iv) N
3
= 25% higher nitrogen than recommended dose, (v) N
= 50% higher nitrogen
than recommended dose and four wheat varieties viz. (i) V
1
4
= BARI gom 21, (ii) V
= BARI
gom 23 (iii) V
3
= BARI gom 24 and (iv) V
= BARI gom 27. The experiment was laid out
in a split plot design with three replications. Data were collected on different parameters of
growth, yield attributes, yield and seed quality of wheat. Results revealed that N
4
(25%
higher nitrogen than recommended dose) gave the highest grain yield (3.41 t ha-1) which was
statistically at par with N
(recommended dose of nitrogen) (3.29 t ha-1). This might be
attributed to highest number of spikes m
2
-2
(194.46), spike length (15.61 cm), number of
spikelets spike
-1
(20.91), number of grains spike
-1
(48.17) and 1000-grain weight (47.08 g).
Out of 4 varieties V
3
(BARI gom 24) showed highest grain yield (3.02 t ha
) which was
statistically similar with V
4
(BARI gom 27) (2.89 t ha
-1
-1
). The variety BARI gom 27 (V
) also
showed higher number of grains spike
-1
(46.65) and 1000-grain weight (49.53 g). In respect
of seed quality, N
(recommended dose) showed higher quality of seed which was
statistically similar to N
2
(25% higher nitrogen dose than recommended) because this
nitrogen dose gave highest germination percentage (96.67 %), vigor index (10.34), shoot
length (19.94cm) and dry weight seedling
3
-1
(0.19 g). In the case of variety, V
(BARI gom
27) showed the higher seed quality attributes of germination percentage (95.20%), vigor
index (10.52) shoot length (20.51cm) and dry weight seedling
-1
(0.18 g). Regarding the
interaction of nitrogen doses and varieties, N
2
V
3
, N
2
V
4
and N
3
V
were shown best in
producing quality seeds. From the above results it was concluded that the recommended dose
and 25% higher nitrogen than recommended dose with BARI gom 27 shows better for
producing higher yield and quality seed.

The experiment was conducted at the farm of Sher-e-Bangla Agricultural University,
Sher-e-Bangla Nagar, Dhaka during the period of July to November 2014 to find out
the effect of seedlings hill
-1
on yield and yield components of hybrid and inbred rice
varieties. The experiment comprised of two factors. Factor A: Rice variety (2)
designated as V
1
: Hybrid (Chamak); V
2
: Inbred (BRRI dhan62) and Factor B: Number
of seedlings hill
-1
(5 levels) named as S
1
: 1 seedling hill
-1
, S
2
: 2 seedlings hill
: 3
seedlings hill
-1
, S
4
: 4 seedlings hill
-1
and S
5
: 5 seedlings hill
-1
. The experiment was laid
out in split-plot design with three replications. Experimental results showed that
varieties had the significant effects on plant height, number of tillers hill
, dry weight
hill
-1
, total tillers hill
-1
, panicle length, number of filled and unfilled grains per panicle,
1000 seed weight, grain yield, straw yield and harvest index. The highest grain yield
(4.06 t ha
-1
) was observed from Chamak (hybrid) while the BRRI dhan62 (Inbred)
gave the lowest grain yield (3.04 t ha
-1
-1
). The highest straw yield was observed from V
1
(4.67 t ha
-1
) and the lower straw yield was recorded from V
2
(4.21 t ha
). Number of
seedlings hill
-1
also significantly affected all the parameters under study. The
maximum number of effective tillers hill
-1
was found from S
2
(12.20), whereas the
minimum number of effective tillers hill
-1
from S
5
(10.27). The highest grain yield was
found from S
2
(4.10 t ha
-1
), whereas the lowest grain yield from S
5
-1
(2.93 t ha
). The
highest straw yield was found from S
2
(4.80 t ha
-1
), whereas the lowest straw yield
from S
5
(4.14 t ha
-1
) which was statistically similar to S
4
(4.21 t ha
). In case of
interaction effect of varieties and number of seedlings hill
-1
, the highest grain yield
was recorded from the combination of V
1
S
2
(4.74 t ha
-1
) and the lowest grain yield
was found from V
2
S
5
(2.55 t ha
-1
) which was statistically similar with V
2
(3.79 t
ha
-1
). From the above results it was appeared that Hybrid (Chamak) variety provided
best yield with 2 seedlings per hill
