An experiment was carried out under the conditions of the green house at the Faculty of Agriculture, University of Aleppo, in order to determine the effect of both gypsum and humic acid on the total porosity and pH of irrigated soils by saline water and wheat yield. The experiment was designed in a split-spilt dissection method, with the main sections comprising three levels of irrigation water salinity (W1:0, W2:3, W3:6 g-1 NaCl). Three levels of gypsum were mixed with soil: (G1:0, G2:25, G3:50 g). Three levels of humic acid were added with irrigation water (H3:48, H2:24, H1:0 kg/h). The coefficient Leaching with irrigation water for W3 and W2 was applied at %10 and %20 of the field capacity, respectively. The results confirmed the effective role of gypsum in mitigating the effect of sodcity in Structure soil damage, and this was reflected by the increase in total porosity values in G3. The results indicated a decrease in pH values within the W3 level of irrigation saline water compared with W2. The results showed the significant role of the gypsum in pH reduction as opposed to that of humic acid. The role of humic acid, especially the H3 level, was evident in increasing the yield and weight of 1000 grains for the wheat, while the G2 level of gypsum was superior in yield. The results showed that the W1 yield was better than W2 and W3.
