Four levels of NaCl salt concentration <em>viz.,</em> 0 (Control), 50, 100 and 150 mM and two varieties of carrot namely <em>Shundori</em> and <em>Kuruda</em> were used for this pot experiment. The two-factor experiment was laid out in randomized complete block design with three replications. The yield and yield components varied significantly between two carrot varieties and intensity of salt concentration. The maximum plant height (33.92 cm), length of leaves (14.51 cm), fresh weight of leaves (9.62 g), percent dry matter content of leaves (21.25 %), length of root (9.05 cm), diameter (11.24 cm), dry matter content of roots (18.18 %) were produced by <em>Shundori</em>. On the other hand, maximum water content of leaves (80.89 %), water content of roots (84.57 %) and weight of roots (10.76 g) were exhibited by <em>Kuruda</em>. Most of the studied parameters showed decreasing trends with the highest level of salinity (200 mM NaCl) producing lowest weight of roots (3.93 g). In case of combined effects of variety and salt concentrations, <em>Kuruda</em> with control condition produced maximum weight of roots (20.62 g) while the minimum weight of roots (3.53 g) was obtained by the combination of <em>Kuruda</em> with the highest level of salt concentration (200 mM NaCl). The result of the experiment revealed that the salinity stress significantly reduced all studied parameters at 100 mM and 150 mM as compared to control and 50 mM NaCl. Therefore, it can be concluded that the variety of <em>Kuruda</em> was found as relatively salt tolerant than <em>Shundori</em>.</p> <p><strong><em>Progressive Agriculture 30 (3): 263-274, 2019</em></strong></p>}, number={3}, journal={Progressive Agriculture}, author={Jahan, I and Hossain, MM and Karim, MR}, year={2020}, month={Jan.}, pages={263–274} }
