Abstract:
The study was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural
University, Dhaka, Bangladesh during the period from October 2011 to March
2012. The experiment consisted of two factors: Factor A: Planting time (three
levels) as T
1
: Planting at 13 November, 2011; T
: Planting at 23 November, 2011;
T
3
M
2
: Planting at 03 December, 2011 and Factor B: Organic manure (four levels) as
0
: Control i.e. no manure application; M
1
: Cowdung @ 15 t/ha; M
: Poultry
Manure @ 12 t/ha and M
: Vermicompost @ 13 t/ha. The experiment was laid out
with Randomized Complete Block Design with three replications. In planting
time, the highest weight of primary curd per plant (427.8 g) and highest yield
(10.6 t/ha) was recorded from T
3
, while the lowest (404.2 g) and (9.91 t/ha) from
T
3
2
. For organic manure, the highest weight of primary curd per plant (484.7 g)
and highest yield (12.0 t/ha) was recorded from M
, while the lowest (253.9 g)
and (6.45 t/ha) from M
0
2
. Due to the interaction effect, the highest weight of
primary curd per plant (532.3 g) and highest yield (13.4 t/ha) was recorded from
T
2
M
2
and the lowest (236.8 g) and (6.68 t/ha) from T
1
M
. The highest benefit cost
ratio (2.31) was noted from T
2
M
2
0
and the lowest (1.26) from T
1
M
. So, planting at
23 November with poultry manure was better for the broccoli production.
