Abstract:
An experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka,
Bangladesh during the period from October, 2018 to April, 2019 to evaluate the
effect of planting times and organic nutrient sources on growth and yield of Brussels
sprouts. The experiment consisted of two factors: Factor A: Planting times (three
levels) as - T
1
: 05 November; T
2
: 20 November and T
3
: 05 December and Factor B:
Organic nutrients sources (four levels) as – N
0
: Control (no manure); N
1
: Cowdung
@ 15 t/ha; N
2
: Mushroom spent compost @ 7.5 t/ha and N
3
: Vermicompost @ 5
t/ha. The experiment was outlined in Randomized Complete Block Design with
three replications. Significant variation was found with the treatments. In case of
planting time, maximum number of marketable buds (21.89/plant) and marketable
yield (8.70 t/ha) were recorded from T
1
and minimum number of marketable buds
(17.22/plant) and marketable yield (5.76 t/ha) were recorded from T
3
. For organic
nutrient sources, maximum number of marketable buds (22.59/plant) and
marketable yield (8.82 t/ha) were recorded from N
3
and minimum number of
marketable buds (14.30/plant) and marketable yield (4.69 t/ha) was recorded from
N
0
. For combined effect, the highest marketable yield (10.92 t/ha) was recorded
from T
1
N
3
and the lowest marketable yield (4.07 t/ha) was recorded from T
3
Economic analysis revealed that T
1
N
3
gave the maximum benefit cost ratio (2.59).
So it can be concluded that, planting at 05 November with vermicompost @ 5 t/ha
provided the best result for growth and yield of Brussels sprouts.
