Effect of levels salinity water on seedling growth of Acacia senegal at the Nursery, North Kordofan state, Sudan

This study was conducted in Shikan nursery, Elobied, North Kordofan, from three sources of Acacia senegal seeds (Al-Rahad, Al-Aabasia and Um- Keradem) at January 2022. This study aims to determent the effect of saline water levels on growth of Acacia senegal seedlings. Different salt water levels were used to irrigate seedlings. The response to salt water stress at general level was good with appearance of significant differences at beginning of experiment and these differences disappeared at end of experiment. This indicates that Acacia senegal seedlings were more tolerant of salt water stress to the level of 2898 ms/cm total dissolved salts (T.D.S), can be used for irrigation, especially for Acacia senegal seedlings with a ph between (7.1-8.4). To reduce seedling death, low salinity levels can be relied upon.
