Abstract:
A pot experiment was conducted at the Horticultural Farm of Sher-e-Bangla
Agricultural University, Dhaka, during the period from October 2021 to March 2022
to enhance the salinity tolerance of red cabbage (Rubi King) using potassium silicate
and potassium nitrate. The treatments consisted of 3 different salinity levels viz., S
0
= Control (± 0.8 dSm
-1
) EC, S
1
= 4 dSm

EC and S

= 8 dSm

EC and application
of potassium silicate and potassium nitrate viz., C

= Control (Water), C
1
= 3 mM
potassium silicate, C
2
= 4 mM potassium nitrate. The experiment was setup in a two
factor Complete Randomized Design (CRD) with three replications. Data on
different growth, biochemical parameters and yield contributing characters of red
cabbage were recorded. It was found that the head weight of red cabbage gradually
decreased by the increase of salinity levels and this reduction rate was decreased by
foliar application of potassium nitrate. Significant variation was recorded on yield
per plant (g) of red cabbage due to different level of salinity. The maximum yield
was recorded from S
0
(807.70 g) whereas the lowest yield (621.80 g) was by resulted
from S
2
. The maximum yield (734.90 g) was recorded from C
2
whereas the lowest
yield (646.80 g) was by C
0
. The maximum yield (867.00 g) was obtained from S
0
,
while the lowest yield (590.80 g) was recorded from treatment combination of S
2
.
It can be concluded that, potassium nitrate was more efficient for salinity tolerance
improvement of red cabbage.
