out in Split plot Design (2 factor) replicated with three times. For this study, factor A- V

The yield attributing characteristics (i.e. plant height (52.18 cm), number of leaves/plant (13.80
leaves), number of pods/plant (49.88 pods), pod length (3.14 cm), seeds per pod (2.50 seeds), 1000
seeds weight (123.5 g), seed yield (2.23 t/ha), stover yield (3.96 t/ha), biological yield (6.19 t/ha)
and harvest index (35.90 %)) and seed quality (seed viability (71.88 %) and seed germination
(85.00 %)) were highest and the timing of 1
st
flowering (30.88 days) and timing of pod maturity
(51.63 days) were lowest for BARI Soybean 6. The yield attributing characteristics (i.e. plant
height (54.60 cm), number of leaves/plant (15.22 leaves), number of pods/plant (61.50 pods), pod
length (3.36 cm), seeds per pod (3.50 seeds), 1000 seeds weight (137.9 g), seed yield (2.55 t/ha),
stover yield (4.41 t/ha), biological yield (6.96 t/ha) and harvest index (36.65 %)) and seed quality

flowering (28.50 days) and timing of pod maturity (49.50 days) were lowest for Biochar (10 t/ha)
+ 70 kg/ha K treatment. Again, BARI Soybean6 along with Biochar (10 t/ha) + 70 kg/ha K showed
the best performance in the yield attributing characteristics (i.e. plant height (55.89 cm), number
of leaves/plant (15.47 leaves), number of pods/plant (66.00 pods), pod length (3.45 cm), seeds per
pod (4.00 seeds), 1000 seeds weight (138.8 g), seed yield (2.63 t/ha), stover yield (4.49 t/ha) and
biological yield (7.12 t/ha)) and seed quality (seed viability (84.00 %) and seed germination (94.00
%)) and the timing of 1
st
flowering (28.00 days) and timing of pod maturity (49.00 days) were
lowest. The combined effect of BARI Soybean 6 with Biochar + 70 kg/ha K showed the best
performance in case of increasing soybean growth, yield and seed quality compared to other
treatments.

HASAN, MD. MEHEDE
A field experiment was conducted in the experimental field of Sher-e-Bangla
Agricultural University to find out the effect of transplanting date on yield and seed
quality of T. aman rice varieties. cultivated during aman season (July 2019 to
December 2019). The experiment comprised two factors viz, factor A: Variety – 3, i)
V
1
= BRRI dhan32, ii) BRRI dhan62 and iii) V
3
= BRRI dhan80; factor B: Date of
transplanting – 4, T
1
= 01 July; T
2
= 15 July; T
3
ii
= 30 July and T
4
= 15 August. The
experiment was laid out in Randomized Complete Block Design (RCBD) with three
replications. Data were collected on different aspects of growth, yield attributes, yield
and seed quality of T. aman rice. Results revealed that, BRRI dhan32 gave the highest
grain yield (5.01 t ha
-1
) and maximum seed germination percentage (87.06%). This
may be attributed to the maximum number of effective tillers hill
-1
(14.83), longest
panicle (28.64 cm), the highest number of filled grains panicle
- 1
(114.16), highest
1000-grain weight (23.84 g) and highest vigor index (2067.54) in this variety. Out of
4 dates of transplanting treatment, T
3
(Transplanting on 30 July) produced the highest
grain yield (5.23 t ha
-1
) and maximum seed germination percentage (90.95%). This
treatment also showed the maximum number of effective tillers hill
-1
(14.99), longest
panicle (28.35 cm), the maximum number of filled grains plant
-1
(119.59), highest
weight of 1000-seed (24.23 g) and highest vigor index (2232.91). Regarding the
interaction of variety and date of transplanting, the interaction of V
1
T
3
(BRRI dhan32
when transplanting on 30 July) was the highest yielder (5.82 tha
-1
) among the other
interactions which was attributed to higher 1000-seed weight. Besides this, the
interaction V
1
T
3
also gave maximum seed germination percentage (92.89%) and
highest vigor index (2377.98). Considering the above result, it may be concluded that
BRRI dhan32 transplanting on 30 July was found superior in producing the highest
yield and best quality seed production.

An experiment was conducted at the Agronomy Farm Sher-e-Bangla Agricultural
University, Dhaka, Bangladesh October, 2019 to March, 2020 to study the influence of some
macronutrients combination (N, P & K) and spacing on the growth and yield of fenugreek
seed (Trigonella foenum-graecum L.). Fenugreek variety BARI Methi-1 was used as
planting material in this study. The experiment consisted of two factors: Factor-A: macro

block design (factorial) with three (3) replications. Data on different growth, yield
contributing and yield parameter of fenugreek were recorded and significant variation was
observed from different treatments. In case of nutrient combinations, seed yield per plot
(332.12g), seed yield (1142.8 kg ha
-1
), stover yield (865.49 kg ha

), germination percentage
(80.30 %) were observed from T

the maximum seed yield per plot (353.20g), seed yield (1251.9 kg ha

) and stover yield
(1271.4 kg ha
-1
) were observed from S

(30×10cm) treatment. The maximum primary

(3.39) was obtained from the T

treatment combination whereas the lowest BCR (1.04)
was from T

treatment combination It can be concluded that, sowing of fenugreek
providing 120 kg N, 90 kg P and 90 kg K nutrient combination with 30 × 10 cm plant
spacing was recorded to be more suitable practice for getting higher yield (1.82 t/ha) and
quality of seed yield of fenugreek.

MD. SHARIEUTULLAH
A field experiment was conducted in the experimental field of Sher-e-Bangla
Agricultural University to find out the effect of different age of seedling on the yield
and seed quality of T. aman rice, cultivated during the Aman season (July 2019 to
December 2019). The experiment comprised two factors viz, factor A: Variety – 3, i)
V
1
= BRRI dhan32, ii) V
2
= BRRI dhan62 and iii) V
3
= BRRI dhan80; factor B: Age
of seedling – A

= 20 days, A

ii
= 30 days and A
4
= 35 days. The
experiment was laid out in two factors RCBD with three replications. Data were
collected on different aspects of growth, yield attributes, yield and seed quality of T.
aman rice. Result revealed that BRRI dhan32 gave the highest seed yield (4.68 t ha
)
and maximum seed germination percentage (88.33%). This may be attributed to
maximum number of effective tillers hill
-1
(17.30), longest panicle (28.53 cm), highest
number of filled seeds panicle
-1
(117.1), highest 1000-seed weight (26.36 g) and
highest vigor index (1991.72) in this variety. Out of 4 different age of seedlings
treatment A
3
(30 days old seedling) produced the highest seed yield (4.83 t ha
maximum seed germination percentage (92.01%). This treatment also showed
maximum number of effective tillers hill
-1
(16.69), longest panicle (28.15 cm),
maximum number of filled seeds plant
-1
(124.9), highest weight of 1000 seed (27.69
g) and highest vigor index (2001.54). Regarding the interaction of variety and
different age of seedling, the interaction of V
1
A
3
(BRRI dhan32 with 30 days old
seedling) was highest yielder (5.12 t ha
-1
) among the other interactions which was
attributed to higher 1000 seed weight. Besides, these interaction V
1
also gave
maximum seed germination percentage (92.86%) and highest vigor index (2152.49).
Considering the above result, it may be concluded that variety BRRI dhan32 (V
1
) and
30 days old seedling (A
3
) and their interaction V
1
A
3
was found superior in producing
highest yield of best quality seed.
