      A factorial experiment was carried out using a completely randomized block design and a split-plot arrangement in a sandy mixture soil, with three factors resulting from the salinity of irrigation water (1.2, 3, and 6 dSm-1) and symbolized (S1, S2, S3) respectively, and organic fertilization (the comparison treatment). , poultry waste 10 mcg ha-1, Agri M40 fertilizer 80 liters ha-1) and their symbol is (M0, M1, M2) respectively, and mycorrhizae (0, 12 and 24 gm ha-1) and their symbol is (F0, F1, F2) respectively. Sequential and three replicates. The results showed a significant decrease in the concentration of calcium and magnesium when adding mycorrhiza to treatment F1, as it reached 3.89 mmol L-1 and 2.40 mmol L-1, respectively, and when treatment F2 reached 3.60 mmol L-1 and 2.22 mmol L-1, respectively, compared to treatment F0, which It recorded 4.42 mmol l-1 and 2.67 mmol l-1, respectively. Plant height, dry weight of shoots, and biological yield also increased significantly, reaching 182.30 cm, 7.31 tons ha-1, and 20.98 tons ha-1, respectively, for treatment F1 and reaching 184.19. cm, 7.65 tons ha-1, and 21.50 tons ha-1, respectively, in treatment F2 compared to treatment F0. Treatment F2 also outperformed treatment F1 in all previous characteristics. Also, by adding organic fertilizer, the concentration of calcium and magnesium in the treatment decreased significantly, reaching 3.78 mmol L-1 and 2.38 mmol L-1, respectively, in the M1 treatment, and reaching 2.98 mmol L-1 and 1.86 mmol L-1, respectively, in the M2 treatment, compared to Treatment M0, the dry weight of shoots, grain yield, biological yield, percentage of NPK in grains, and percentage of roots infected with mycorrhizae increased significantly, reaching 7.06 tons ha-1, 10.57 tons ha-1, 20.54 tons ha-1, 1.68% and 0.48%. And 2.40% and 32.22%, respectively, in treatment M1, which amounted to 7.86 tons ha-1, 10.92 tons ha-1, and 21.88 tons ha-1, and 1.81%, 0.57%, 2.64%, and 44.07%, respectively. In the M2 treatment compared to the M0 treatment, the Agri M40 M2 fertilizer was superior to the M1 poultry waste in all previous characteristics.
