Abstract
Salinity is a major challenge in crop cultivation, but tolerant genotypes can adapt physiologically to cope with stress. A pot culture experiment conducted during the period of July 2021 to June 2022 at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, evaluated the impact of salt stress on eight chili genotypes at three salinity levels (T1=3 dS/m, T2=6 dS/m, T3=9 dS/m NaCl) compared to a control (T0=0 dS/m NaCl). Varieties and stress interaction were estimated based on agromorphogenic and physiological traits. Increasing salinity levels significantly reduced plant growth traits like height, number of branches, days to first flowering, and leaf area, as well as fruit traits such as length, girth, weight, and number per plant. Among the genotypes, G4 was highly tolerant to salinity, while G5 and G6 are recommended for mild to moderately saline prone areas.
