Abstract:
The experiment was conducted at the experimental field of Sher-e-Bangla Agricultural
University. Dhaka during the rabi season from November 2014 to February 2015 to study
the effect of source of nitrogen and weed control method on the performance of mustard
cv. BARI Sarisha-14. The treatment consisted of four sources of nitrogen viz. N
0
= no
= NPK mixed fertilizer and N
3=
Urea super
granule, and three different weeding methods viz. W
o
= No weeding, W1
= hand weeding
nitrogen (Control), N
1
= Prilled urea. N,
-
and W-,= Uerbicidal weeding. The experiment was laid out in a Split plot design with
three replications. Results showed that a significant variation among the treatments in
respect majority of the observed parameters. The tallest plant (56.16 cm) was recorded
with prilled urea. The maximum number of branches per plant (5.17), number of siliquae
per plant (26.34) and number of seeds per silliqua (29.06) were also produced by prilled
urea. The highest seed yield (1139.00 kg hi') was obtained from prilled urea. On the
other hand, the tallest plant (55.49 cm) of mustard was produced with hand weeding. The
maximum number of branches per plant (4.63), number of siliquae per plant
(22.75)
and
number of seeds per silliqua (26.31) was obtained from hand weeding. The highest seed
yield (1040.00 kg hi') was also obtained from hand weeding. The interaction effect of
nitrogen and weeding had significant effect on almost all parameter. The highest seed
yield (1382.00 kg hi') was obtained from prilled urea with hand weeding interaction
treatment.
