Abstract
An experiment was accomplished at 2a Biotech lab, Dept. of Horticulture,
Sher-e-Bangla Agricultural University, Dhaka, during August, 2017- July,
2018. Four LED light treatments viz. T
0
: White; T
1
: White + Blue; T
2
: White +
Red; T
3
: White + Blue + Red were used in this experiment. The experiment
was laid out in a Completely Randomized Design with three replications. In
case of tomato, the highest plant height (172cm) was observed from (T
1
)
treatment, the maximum leaf number (122) from (T
3
) treatment, the highest
leaf area (115.2 cm
2
), 1
st
flowering (32 days), flower cluster (22),
flower/cluster (22), 1
st
fruiting (36 days), fruit/cluster (16), fruit length (44.3
mm), fruit diameter (25.6 mm), brix (3.6%), fruit number (117), fruit weight
(9.88g) and yield/plant (1.0 kg) were found from (T
3
)
treatment where
minimum were found in T
0
treatment. In case of brinjal, the highest plant
height (83.60 cm) was found from T
1
treatment, the maximum leaf number
(23), leaf area (455 cm
2
), branch no. (5.0), fruit length (26.2 cm), fruit breadth
(6.8 mm), fruit number (35.52), single fruit weight (90.5g) and yield/plant
(2.34 kg) were observed from (T
3
)
treatment while the lowest value in these
parameters were found from T
0
treatment . So, the vegetative growth of tomato
and brinjal under T
1
treatment and reproductive growth under T
3
treatment
were found better.
