Abstract:
Salinity is a major abiotic stress inducing morphological and yield changes in plant as
well as limiting production. So a pot experiment was conducted during December 2021
to March 2022 at Agroforestry farm, Sher-e-Bangla Agricultural University Sher-eBangla
Nagar,
Dhaka-1207.
It
was
done
to
evaluate
the
changes
in
morpho-physiological
and
yield
characteristics
of
three
field
pea
varieties
(BARI

3) to salinity under different levels. The three salinity levels (4 dS/m, 8dS/m,
12dS/m) along with a control were inclined by irrigation of NaCl salt solution. The
experiment was placed out following two factors Complete Randomized Design with
three replications. Results indicated that in response to different salinity level, the three
genotypes showed clear differences in the changes in plant height, leaf length, number of
leaf, chlorophyll content, relative water content, salt tolerant index, number of pod,
number of seed, pod length, pod weight and 100 seed weight and yield of field peas which
were significantly decreased with the increased of salinity. Vegetative stage is being more
sensitive than flowering and pod-filling stages. The tallest plant (57.05cm), number of
leaf per plant (9.50), the highest salt tolerant index value (38.47%), relative water content
(37.69%), number of pod per plant (7.33), number of seed per pod and yield (2.23g) were
observed from BARI motor 2 at 12 dS/m. Therefore, BARI Motor 2 was the most salt
tolerant among the varieties in terms of growth and yield production.
