Abstract:
A study was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural
University, Dhaka, Bangladesh during the period from October 2016 to
February 2017. The experiment consisted of two factors: Factor A (salinity
level): S
0
= 0 dSm
-1
, S
1
= 4 dSm

II
= 7 dSm
-1
, S
3
= 10 dSm
; Factor B
(mitigation level): M
0
= 0, M
1
= 1 mM of Salicylic Acid, M
2
= 10 µm of
Jasmonic Acid, M
3
= 1 mM of Salicylic Acid with 10 µm of Jasmonic acid.
The experiment was laid out in Randomized Complete Block Design with 4
replications. Various morphological, yield and yield contributing characters
varies due to increasing salinity and application of salicylic acid and Jasmonic
acid singly or in combination have significantly mitigate this effect. In terms of
salinity, the highest yield per hectare (81.04 t) was recorded from S
0
, while the
lowest yield (17.40 t) was recorded from S
3
. In terms of mitigation levels, the
highest yield per hectare (46.55 t) was found from M
3
, whereas the lowest yield
(43.84 t) was recorded from M
0
. In combination, the highest yield per hectare
(83.32 t) was recorded from S
0
M
3
, whereas the lowest yield (16.45 t) was
recorded from S
3
M
0
. Therefore, combined application of salicylic acid with
Jasmonic acid seems to mitigate salt stress in tomato.
