Abstract:
The experiment was conducted to investigate the effect of sowing time and
nitrogen
Of)
the growth and yield of French bean (IJARI Zhar Sheern-!) at the
Ilimi of Sher-e-Bangla Agricultural University. Dhaka during the period of
November. 2006 to March, 2007. The experiment included two Ihetors: Factor
A: Four sowing time (T
1
l5 November, 'F
2
-30 November, T

=l5 December
and 1 4
30 December) and Factor B: Four nitrogen level (N
0
=0 Kg N/ha,
N1
-45 kg N/ha. N
2=-90 kg N/ha and N
3
135 kg N/ha). The experiment was laid
out in Randomized Complete Block Design (RCBD) with three replications. In
case of sowing time. T

give highest yield of green pod (15.6 t!ha) and lowest
(11.3 r/ha) was from 1

. Incase ol nitrogen. N
2
produced the lughesi yield
(15.7 t/ha) and lowest (9.8 IJha) was from N
o
. For combined effect l'
1
N, give
the highest yield (17.9 tlha) and lowest (8.4 tJha) was from l.
1 N0
. On the basis
of economic analysis the highest net return (TK. 1,70,023 /lla) and the highest
benefit cost ratio (2.7) were obtained lioni the treatment combination of T
1 N7 .
It may be concluded that 15 November sowing with 90 kg N/ha is best for
growth and yield of french bean.
