Abstract:
A pot experiment was conducted in the Horticulture Farm of Sher-e-Bangla
Agricultural University, Dhaka, during the period from April 2016 to September
2016. The two factors experiment was laid out in Complete Randomized Design
with four replications. Factor A is different doses of salicylic acid viz. S
0
: Control,
S
1
: 0.25 mM Salicylic acid, S
2
: 0.5 mM Salicylic acid and factor B is different
levels of micronutrients viz. M
0
: Control, M
1
ii
: 20 mg of zinc, M
2
: 2 mg of boron,
M
3
: 10 mg zinc + 1 mg boron, M
4
: 20 mg zinc + 2 mg boron. The experimental
results showed that micronutrients and salicylic acid significantly affects
morphology, physiology, yield contributing characters and yield of tomato. In
case of salicylic acid, the highest yield per plant (1260.40 g) was found in S
2
and
the lowest yield (1099.50 g) was found in S
0
. In case of micronutrients, the
highest yield per plant (1691.50 g) was found in M
4
and the lowest yield (793.50
g) was found in M
0
. The interaction effect of salicylic acid and micronutrients
influenced all most all parameters of morphophysiological and yield attributing
characters of tomato, where the highest yield was (1872.22 g) was found in S
4
(20 mg zinc + 2 mg boron and 0.5 mM salicylic acid) and the lowest yield
(736.04 g) was found in S
0
M
0
(Control Condition). These results suggest that
salicylic acid and micronutrients can alleviate the detrimental effect of summer to
increase the yield of tomato.
