Abstract: 

This study was conducted to evaluate the effect of different irrigation water salinity levels (0.75 (control), 2.99, 5.3, 7.5 dS•m⁻¹) on the vegetative growth of mango seedlings (Mangifera indica L.) cv. “Timor” for 90 days. The experiment was carried out under plastic tunnel conditions in Ibb Governorate, Yemen, using a randomized complete block design (RCBD) with four replicates. Results showed significant differences (p < 0.05) among salinity levels in the studied traits (stem length, number of leaves, and leaf area). Irrigation with 2.99 dS•m⁻¹ resulted in the highest increase in stem length (32.5%), whereas the control treatment (0.75 dS•m⁻¹) recorded the highest mean values for number of leaves (9.8 leaves/seedling) and leaf area (32.79 cm²). High salinity levels (≥ 5.3 dS•m⁻¹) significantly reduced all measured vegetative growth traits. Overall, the seedlings showed tolerance at low and moderate salinity levels, while higher concentrations negatively affected growth.
