Abstract:
A pot experiment with six aman rice varieties viz. BRRI dhan34, BRRI dhan38,
Binadhan-9, Binadhan-13, Kalijira and Rajbhogh was conducted at the
experimental shed of the Department of Agronomy, Sher-e Bangla Agricultural
University, Dhaka during the period of June- December, 2014 to investigate the
effect of salinity on the growth, physiology and yield of some aromatic rice
under different salt stress condition. The experiment was carried out with five
salt stress treatments viz. control (N
0
), 25 mM (N
25
), 50 mM (N
), 75 mM
(N
75
) and 100 mM (N
). Salt stresses significantly reduced the plant height
and tiller hill
-1
100
of six varieties at all growth duration. Leaf relative water
content (RWC) and chlorophyll (chl) content also reduced due to salt stress. At
harvest, salt stresses reduced the effective tiller hill
-1
, number of filled grain
panicle
-1
, 1000 grain weight, grain yield and straw yield of six varieties.
Binadhan-9 and BRRI dhan38 performed better under saline condition. On the
other hand, local variety Kalijira did not perform well under saline condition.
