Abstract:
The research work was conducted in the net house of the department of agronomy, Sher-eBangla
Agricultural
University,
Sher-e-Bangla
Nagar,
Dhaka
during
the
period
from
July,
2019
to
December,
2019
to
study
the
yield
and
quality
of
jute
seed
as
influenced
by
variety
and
sowing
date
at
late
sown
condition.
The
two-factor
experiment
was
laid
out
in
the
Randomized
Complete
Block
Design
RCBD
(factorial)
with
three
replications.
Two
factors
viz.
Factor
A,
four
jute
varieties;
V
1
= BJRI Tossa Pat-8, V
2
= BJRI Tossa Pat-6, V
3
= BJRI Tossa Pat-5 and V
4
=O-9897; and
Factor B; four sowing dates S
1
= July 7, S
2
= July 21, S
3
= August 7 and S
4
= August 21 were
considered for the experiment. The result revealed that variety V
3
(BJRI Tossa Pat-5) showed the
highest seed yield (1303.94 kgha
1
(27.78), number of seeds pod
-1
-1
) which might be attributed to the highest number of pods plant
(176.48) and weight of seeds pod
-1
(0.40g). This variety also
produced the tallest plant (171.63cm) and maximum number of branches plant
(3.73). Among
the different sowing dates, crop sown at 7 August (S
3
) showed the maximum seed yield (1203.74
kgha
-1
) which might perhaps the highest number of pods plant
-1
(24.75), pod length (6.76 cm),
pod diameter (5.80 mm), number of seeds pod
-1
(175.96), weight of seeds pod
(0.39 g) and
weight of 1000 seed (1.79 g) in this treatment. Interaction of V
3
S
3
(Variety BJRI Tossa Pat-5 with
sowing date August 7) gave the highest seed yield (1390.2 kgha
-1
) along with the highest number
of pods plant
-1
(29.98), pod diameter (6.26 mm) and number of seeds pod
-1
(186.26). Considering
seed quality, the interaction V
3
S
3
also showed the highest germination (97.66%), seedling length
(4.97 cm), oven dry weight of seedling (51.59 mg) and lowest electrical conductivity (8.17 dSm
).
Considering the above result, it may be concluded that variety V
3
1303.94 kgha
and sowing date
S
3
1203.74 kgha
-1
and its interaction V
3
S
3
1390.2 kgha
-1
seems promising of jute seed production
in late sown condition.
