Abstract:
The field experiment was conducted during rabi season, November 2018 to
February 2019 in the experimental field of Sher-e-Bangla Agricultural
university, Dhaka to determine effects of nitrogen and zinc on growth and yield
of mustard (Brassica campestris) variety BARI Sarisha-15. The treatments of
the experiment was consisted of three levels of nitrogen i.e., 0 kg N/ha (N
0
), 80
kg N/ha (N
1
) and 120 kg N/ha (N
2
II
); three levels of zinc i.e., 0 kg Zn/ha (Zn
0
), 2
kg Zn/ha (Zn
1
), 3 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 120 kg N/ha (N
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, N
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
nitrogen and zinc had significant effect on all the growth and yield parameters.
Except the harvest index, the N
2
Zn
2
treatment combination or 120 kg N/ha with
3 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 120 kg N/ha with the
combination of 3 kg Zn/ha increased the growth and yield of mustard.
