Abstract:
A field experiment was eondLzcted at the rnsearch Ihrrn of Sher-e-lIangla Agricultural
University, Dhaka. Bangladesh during the rahi season of 2005-06 to study the elects of
nitrogen (N) and boron (B) on growth, yield and yield attributes of mustard cv. Tori-7.
The experiment was laid out in a Randomized Complete Rlock l)esign (RCBD) with 3
(three) replications of each treatment. There were 16 treatments. The treatments consisted
of4
(four) levels ofN (0, 50, 100 and 150 kg haj designated as No,
N50, Mo
o , and N1 50,
respectively and 4 (four) levels of B (0, 1, 2 and 3 kg ha') designated as 13, B, B2 and
B3
, respectively. There was a positive impact of each nutrient and their interaction on
growth. yield and yield attributes of mustard. All the plant parameters were increased
with increasing level of N except number of branch per plant, weight of 1000 seeds and
seed yield. The highest seed yield (1.62 t/ha) was obtained with application of N @100
kg/ha and the minimum was recorded in No (control) treatment. Similarly, application of
2 kg/ha produced the highest yield of 0.97 i/ha, which was 31% higher over control
(0.74 i/ha). The combined effect of N and 13 had positive impact on growth, yield.

treatment. The highest N, B. K and S uptake by seeds was found in
treatment, but the highest P uptake was found in N

treatment. From the
present findings it can he interred that application of N @ 150 kg/ha and B
@2
kg/ha is
the most suitable combination to achieve the highest seed yield (1.96 i/ha) of mustard
which was
165.0%
higher over control treatment (0.74 i/ha).
