Abstract:
The field experiment was conducted during rabi season, November 2021 to
February 2022 in the experimental field of Sher-e-Bangla Agricultural
university, Dhaka to determine effects of boron and zinc on growth and yield of
mustard (Brassica campestris) variety BARI Sarisha-14. The treatments of
the
experiment was consisted of three levels of boron i.e., 0 kg B/ha (B
0
), 1 kg
B/ha (B
1
) and 1.5 kg B/ha (B
2
); three levels of zinc i.e., 0 kg Zn/ha (Zn
0
), 3kg
Zn/ha (Zn
1
), 5 kg Zn/ha (Zn
2
). The experiment was laid out in the two
factors
Randomized Complete Block Design (RCBD) with three replications. Results
of this experiment showed a significant variation among the treatments
in
respect of the majority of the observed parameters. The 1.5 kg B/ha (B
2
)
gave
the highest plant height, number of branches per plant, number of seeds per
siliquae, number of siliquae per plant, length of siliquae and 1000 seed
weight.
Again, B
2
resulted the maximum seed yield (1.70 t/ha), stover yield,
biological
yield and harvest index. In addition, except siliquae length and
harvest index, 3
kg Zn/ha (Zn
2
) resulted highest values in all parameters while the lowest values
were found in Zn
0
treatment. The interaction between
boron and zinc had
significant effect on all the growth and yield parameters.
Except the harvest
index, the B
2
Zn
2
treatment combination or 1.5 kg B/ha with
5 kg Zn/ha gave
maximum values on all parameters including seed yield (1.82 t/ha). Based on
these results, it can be suggested that 1.5 kg B/ha with the combination of 5 kg
Zn/ha increased the growth and yield of mustard and this may be the best
combination for the growth and yield of mustard.
