Abstract: 

This experiment was carried out in Deir Ezzor Syrian city – Seaalo Research Station – The General Commission for Scientific Agricultural Research(GCSAR) to determine the influence on some soil characteristics and yield of triticale crop Tertiary upon irrigation with different salinity irrigation water.  Randomized-complete- block design consisting of three treatments and three replicates (fresh, salt, alternate) over cropping season(2018-2019). The results showed a significant decrease in yield with increasing the salinity of irrigation water where the biological yield (13.26,11.59, 11.29) tons/hectare respectively, and the grain yield (4.17, 3.48, 3.17) tons/hectare respectively. Irrigation with fresh water( I1)  (Ec=1.12 dS/m) leached a part of salt from the soil profile which (Ec) of 1:5 soil extraction reaches to Ec=0.47 dS/m, Salts accumulation in the soil was greater for the high salinity irrigating water treatment ( I₂) (Ec=19.61 dS/m) which increased the  (Ec) of soil extraction  1:5  to 8.05 dS/m, while a small amount of salt accumulation in the soil upon alternate irrigation ( I₃) (Ec= dS/m) which increased the  (Ec) of  soil extraction 5:1  of the soil to 2.15 dS/m.

Keywords: alternating irrigation, salt water, triticale, biological yield, grain yield, Ec .
