Abstract:
A pot experiment was conducted to study the effects of salinity on growth, yield
and nutrients content of capsicum during the period of November 2021 to March
2022 at the net house and laboratory of Agro Environmental Chemistry,
Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University,
Sher-e-Bangla Nagar, Dhaka-1207. Two capsicum varieties viz. V
1
(ASTHA F1)
and V
2
(BARI capsicum-1) were taken to study the effects of salinity on growth,
yield and nutrients content at five levels of salinity viz. S
0
(0 dS/m), S
1
(3 dS/m),
S
2
(6 dS/m), S
3
(9 dS/m) and S
4
(12 dS/m). The experiment was laid out in
Completely Randomized Design (CRD) with three replications between two
varieties, V
1
(ASTHA F1) showed better result on growth parameters, yield
contributing characters, and yield. The higher fruit yield plant
-1
was recorded from
V
1
(ASTHA F1) as compared to V
2
(BARI capsicum-1). Different salinity levels
showed significant effects on growth and yield parameters of capsicum. Salinity
levels did not show positive effects on growth and yield of capsicum. Growth
parameters and yield of capsicum decreased with the increase of salinity levels.
The control treatment S
0
(0 dS/m) gave the highest capsicum yield (g plant
)
followed by S
1
(3 dS/m); whereas S
4
(12 dS/m) produced lowest yield. The variety
Astha F
1
was found superior to BARI Capsicum-1 in respect to growth and yield
of capsicum and highest number of fruits (7.60) single fruit weight (79.87 g) and
yield plant
-1
(607.01 g) were achieved with Astha F1 variety of capsicum when no
salinity was used. All the parameters studied reduced with increase in levels of
salinity. Nutrients content studied were also affected due to increase in salinity
except Na.
