Abstract:
A pot experiment was conducted in the Horticulture Farm of Sher-e-Bangla
Agricultural University, Dhaka, during the period from November 2016 to March
2017. The two factorial experiment was laid out in Complete Randomized Design
with four replications,factor A: different levels of salinity viz. S
: control (without
salt), S
1
: 4 dS/m, S
2
: 8 dS/m, S
3
: 12 dS/m and S
4
0
: 16 dS/m and factor B: three
concentration of salicylic acid as mitigating agent of salt stress viz. A
:
0.50mM SA and A
: 1 mM SA. The experimental results showed that different levels
of salinity significantly affects the morphological charactersand yield of
tomato.Exogenous application of salicylic acid significantly increased the
morphological characters, yield contributing characters and yield of tomato in both
saline and non-saline conditions.In case of salinity the highest yield (3.03 kg) was
found in S
0
2
and the lowest (0.59 kg) from S
treatment and in case of salicylic acid,
the highest yield(2.27kg) was found in A
1
4
and the lowest(1.86) from A
. For treatment
combination the tallest plant (82.50 cm), highest number of fruit/plant (42.50),
maximum weight of individual fruit (77.79 g) and yield/plant (3.30 kg) were produced
from S
0
A
1
(control + 0.50 mM SA) whereas the lowest value from S
4
0
: 0 mM SA, A
0
A
(16 dS/m+ no
SA). The exhibits result suggests that exogenous application of salicylic acid can
effectively alleviate the deleterious effect of salt stress in tomato
