Abstract:
The present study was carried out at the Agronomy experimental field of Sher-eBangla
Agricultural
University,
Dhaka,
Bangladesh
during
the
period
from
November
2020
to February 2021 to study the growth and yield response of different brassica
oilseeds species to boron and selenium. Two factors experiment consisted of three
varieties viz., V
1
(BARI Sarisha-16), V
2
(BARI Sarisha-14) and V
3
(BARI Sarisha-17)
with four doses of boron and/or selenium viz. control treatment S
0
(no boron or
selenium), S
1
(Boron; 1 mM spray), S
2
(Selenium; 25 µM spray) and S
3
(Boron+
Selenium; 1 mM + 25 µM spray) were considered. There were 12 treatments
combinations. The experiment was laid out in the two factors Randomized Complete
Block Design (RCBD) with three replications. The variety V
1
(BARI Sarisha-16)
showed higher plant growth and dry matter accumulation and also gave the maximum
seed yield (3008 kg ha
-1
) compared to V
2
(BARI Sarisha-14) and V
3
(BARI Sarisha17).
Similarly, S
3
(Boron+ Selenium) treatment showed the best performance on
growth, yield contributing parameters and also gave the highest seed yield (2323 kg
ha
-1
) compared to other treatments of boron or selenium treatments. Regarding
treatment combination of variety and boron + selenium, significant variation was
found for most of the parameters. Treatment combination of V
1
S
3
showed better
performance on different parameters and gave the highest seed yield (3137 kg ha
)
with highest harvest index (35.32%) but V
3
S
3
gave the highest stover yield (6587 kg
ha
-1
) whereas, V
2
S
0
gave least performance for the most of the parameters. From the
above results, it may be concluded that among variety, V
1
(BARI Sarisha-16) is better
than V
2
(BARI Sarisha-14) and V
3
(BARI Sarisha-17) regarding yield performance.
Again, together application of Boron + Selenium is better than individual application
of Boron or Selenium regarding growth and yield performance. As a result, V
1
S
3
performed best regarding yield of mustard compared to other treatment combinatio
