Abstract:
Salinity is one of the most significant abiotic factors in arid and semi-arid areas of the
world. This study was conducted to assess the potential for salt tolerance of cowpea
genotypes during the germination and early vegetative growth. From the germination
test, twenty best performed genotypes were grown at 0, 4, 8 and 12 dS/m at
greenhouse of Bangladesh Agricultural Research Institute, Gazipur. The experiment
was laid out in two factors Complete Randomized Design with two replications.
Factor A was twenty cowpea genotypes and Factor B was four NaCl concentrations.
From the result, it was found that TVU-2398 and TVU-1330 showed the highest
SPAD value (53.1 and 53.62 SPAD unit). In the leaf, the highest Na
was found in
TVU-1330 (0.206%) and K
+
in TVU-2398 (0.24%) and TVU-1330 (0.242%). In case
of stem, the highest Na
+
was found in TVU-1330 (0.29%) and TVU-2398 (0.29%)
and K
+
in TVU-1330 (0.206%). So, the genotypes TVU-1330, TVU-2398 and TVU1059
were
performed
best
under
salinity
condition
than
other
genotypes.
