Abstract:
Salinity is a severe limiting factor for vegetable production. Therefore, a pot
experiment was conducted at Sher-e-Bangla Agricultural University, from November
2019 to April 2020 to evaluate the performance of different tomato varieties e.g.
BARI Tomato 2 (V1), BARI Tomato 15 (V2), and BARI Tomato 16 (V3) under
different level of salinity e.g. 0 mM (S0), 75 mM NaCl (S1) and 150 mM NaCl (S2)
in completely randomized design with three replications. The experiment revealed
significant negative influence of salinity which decreased plant height, leaf number,
branch number, chlorophyll content, growth rate, fresh and dry weight, fruit number
etc. resulting yield loss. Damaged by S2 salinity is more severe than the S1. In
normal condition V2 produced highest yield following V3 and V1. But severe salinity
stress reduced yield by 32.66%, 43.9% and 42.8% in V1, V2 and V3 respectively. So,
considering yield performance V1 variety is more tolerant to salinity than the other
tested variety.
