A factorial experiment succeeded in its conduct on maize (Zea mays L.) using a completely randomized block design with split-plot arrangement in sandy loam. The different organic fertilizers (control treatment, poultry manure at 10 μg ha^-1, and Agri M40 fertilizer at 80 L ha^-1) received the symbols M0, M1, and M2, respectively. The results showed a significant decrease in sodium and chloride concentrations once adding mycorrhizas for treatments F1 and F2. It has reached 16.56 mmol L^-1 and 15.71 mmol L^-1, respectively. For chloride concentration, it was 11.68 mmol L^-1 and 10.80 mmol L^-1, respectively, compared with the control treatment (F0), which achieved 17.12 for sodium and 12.40 mmol L^-1. The maize grain yield and nitrogen concentration also increased for the F2 treatment (10.57 μg ha-¹, 1.68%, 0.48%, and 32.22%). The M2 treatment reached 10.92 μg ha^-1 grain yield, 1.81% N, 0.57% sodium, and 44.07% chloride, compared with the control treatment (10.25 μg ha^-1, 1.58%, 0.41%, and 27.78%, respectively). The M2 treatment was superior to treatment M1 in all previous characteristics. The percentage of root infection with mycorrhizae in treatment M1 was 10.57 μg h^-1, 1.68%, 0.48%, and 32.22%, respectively, and in treatment M2, it was 10.92 μg h^-1, 1.81%, 0.57%, and 44.07%, respectively, versus the control treatment (10.25 μg h^-1, 1.58%, 0.41%, and 27.78%, respectively).

Keywords: Maize (Zea mays L.), mycorrhizas, organic fertilizer, saline irrigation water

Key findings: The maize (Z. mays L.) grain yield, the concentration of nitrogen in the grains, and the percentage of mycorrhizal infection of the roots had increased for the F2 treatment. It was 10.81 mg ha^-1, 0.54%, and 55.56%, respectively, compared with the F0 treatment. The F2 treatment was also significantly higher than the F1 treatment in all stated characteristics.
