All the selected cultivars were grown by using BARI standard hydroponic solution. Five salinity levels were considered as treatments such as 3, 4, 5, 6 and 7 dS m<sup>-1 </sup>using different NaCl concentrations corresponding to the nutrient solution which were noted as T<sub>1</sub> to T<sub>5</sub> and T<sub>0 </sub>was used as control where salinity level was 2.3 dSm<sup>-1</sup>.  Four Napier cultivars were grown with 4 replications under each salinity condition and all the treatments were arranged in a Randomized Complete Block (RCB) design. Shoot presence or absence per cutting and leaf condition were determined weekly. The results revealed that the biomass yield, number of tillers, leaf numbers, tiller height, shoot presence or absence per cutting, leaf condition, and DM   and CP content among all the cultivars were decreased linearly with the increased of salinity levels. On the basis of different morphological and nutritional parameters, tolerance level of different cultivars of Napier grass to salinity stress can be rated as: BLRI Napier-4>BLRI Napier-3 > BLRI Napier-2 >BLRI Napier-1. Further study need to determine the suitability for large scale adaptation under on-farm conditions.</p><p><strong><em>Bang. J. Anim.
