Abstract

In a pot experiment in the National Research Center's greenhouse, wheat (Triticum aestavim L.) grains of the variety Sakha-94 were sowed on November 15 (winter 2019/2020 season). The salinity treatments were started three weeks after sowing until harvest. Plants were sprayed with salicylic acid (0, 100-ppm, 200-ppm) plus calcium nitrate at three weeks and fifth weeks after sowing and the control plants were sprayed with distilled water. Data showed that the yield, and yield traits except spike length were decreased by salinity treatments. grains content of N, P, K, and Mn decreased as salinity increased but the reverse was true for Ca, Mg, Na, Cl, Fe, and Zn, which increased as salinity stress increased up to the highest level used. Data revealed that both chemicals increased the yield, and yield traits. Data cleared the synergistic effect of adding calcium plus salicylic acid on these criteria. Except for Na and Cl, percentages of different nutrients measured increased by both added compounds but the increment by combination of both exceeded those added solitary. Spraying salicylic acid or calcium improved the yield, and yield traits. The mineral status of wheat but adding these chemicals in combination was more effective under irrigation with saline water.
