Abstract:
n experiment was conducted at Sher-e-Bangla Agricultural University to evaluate
the influence of growth media on off-season growth and yield performance of lettuce
varieties in vertical garden. The experiment comprised of two factors, viz., Lettuce
varieties (Green wave,V
1
and New red fire, V
) and Growth media (Control (100%
Soil) P
0
2
, SVC (40% Soil + 40% Vermicompost + 20% Cocodust) P
, SV (50% Soil +
50% Vermicompost), P
2
1
and SVS (20% Soil + 40% Vermicompost + 40% Spent
Mushroom Compost), P
). Among the lettuce varieties, the highest yield per growth
device (0.63 kg) was found from V
3
1
and the lowest (0.60 kg) from V
. Considering the
growth media, P
1
2
produced the highest yield per growth device (0.67 kg) and the
lowest (0.57 kg) was from P
. Regarding the interaction effect, the highest yield of
individual growth device (0.71kg) was obtained from treatment combination V
0
and
the lowest (0.54 kg) from V
2
P
. According to single treatments and treatment
combinations V
1
, P
1
and V
1
P
1
0
performed significantly
better in terms of plant height,
leaf number per plant, leaf area, circumference of canopy and fresh and dry weight of
individual plants. V
2
P
1
performed better than others for marketable qualities and
safety parameter. The highest (17011BDT) and lowest (13440BDT) gross income was
obtained from V
1
P
1
and V
2
P
treatment combination, respectively. The highest (1.37)
and lowest (1.04) benefit cost ratio was noted for V
0
1
P
1
and V
treatment
combination. So, Green Wave variety with SVC mixture (40% Soil + 40%
Vermicompost + 20% Cocodust) can be economically used for summer lettuce
production in vertical garden.
