Abstract:
A pot experiment was conducted in the Horticulture Farm of Sher-e-Bangla Agricultural
University, Dhaka, during the period from November 2016 to April 2017. The two factors
experiment was laid out in Completely Randomized Design with four replications. Factor
A was different levels of salinity induced by sodium
ii
0
: 0 ds/m, S

d/sm, S

:12 ds/m, S
:16 ds/m and factor B was different concentration of Salicylic Acid
viz. A
0
: 0 mM, A

4
: 0.5 mM, A
: 1 mM. The experimental results showed that different
levels of salinity significantly affects the morphological characters, yield contributing
characters and yield of chilli plants. The higher levels of salinity showed greater reduction
of growth, development and yield component to control. The highest plant height, branch
number/plant, leaf chlorophyll content as measured in SPAD value, leaf area, canopy size,
fruit length and breadth/plant, number of flower and fruit/plant and yield
2
and
lowest
. For treatment combination, the maximum yield/plant

whereas the lowest value from S

. Finally, this result suggests
that application of salicylic acid can effectively reduce the deleterious effect of salt stress
in chilli.
