A pot experiment was conducted in Kirkuk Governorate/Hawija District/Al-Riyadh Sub-district during the 2025 growing season to study the effect of soil salinity levels (3.64, 7.04, 10.32, and 14.00 dS m-1) and Irrigation Water Salinity (4.00, 8.00, 12.00, and 16.00 dS m-1) on the vegetative growth, yield, and qualitative characteristics of Salicornia cultivar ICBA-10. The experiment was conducted using a complete block design (RCBD) with six replications. Fresh and dry weight measurements were taken from three replications, while yield measurements were taken from the remaining three. The results showed that both soil and Irrigation Water Salinity had a significant effect on the studied characteristics. The average plant height increased from 44.44 cm at the lowest soil salinity level to 55.50 cm at the highest level. It also increased with increasing Irrigation Water Salinity, from 45.23 cm to 54.58 cm. The highest plant height (60.40 cm) was recorded at the intersection of the highest soil and Irrigation Water Salinity levels. Regarding the fresh weight of the foliage, it increased from 177.57 g plant⁻¹ at the lowest soil salinity level to 225.29 g plant⁻¹ at the highest level. With increasing Irrigation Water Salinity, it increased from 183.07 g plant⁻¹ to 223.34 g plant⁻¹, while the highest fresh weight (252.07 g plant⁻¹) was recorded at the intersection of the two highest salinity levels. Dry weight increased from 36.36 to 46.95 g plant⁻¹ with soil salinity and from 37.74 to 45.83 g plant⁻¹ with Irrigation Water Salinity, with the highest dry weight (52.21 g plant⁻¹) recorded at the overlap between the two highest levels. Grain yield gradually increased from 5.53 g plant⁻¹ to 8.90 g plant⁻¹ with soil salinity and from 5.66 to 9.06 g plant⁻¹ with Irrigation Water Salinity, with the highest yield (11.33 g plant⁻¹) recorded at the overlap between the two highest levels. Likewise, protein concentration improved from 20 % to 22.50 %. The highest concentrations of protein and oil (23.84% and 28.40% respectively) were recorded at the intersection of the highest soil and irrigation water salinity levels. were reached at the overlap between the two highest levels of soil salinity and irrigation water, indicating a synergistic effect that promotes vegetative growth, dry matter accumulation, and plant quality yield.
