A field experiment was carried out during the winter season 2020-2021 at research station of the College of Agriculture, University of Al-Muthanna (Al - Bandar) to study the effect of spraying with nano silica and salinity levels of irrigation water on the growth and yield of wheat. The experiment was applied in a strip split plot design. With three replications, the spraying included three concentrations of silica (3, 6, 9 ppm) and three concentrations of irrigation water salinity (3, 6, 9 ds m −1 ). The results indicated that the level of 9 ppm sprayed exceeded significantly in the following traits and gave the highest means.: plant height 84.26 cm, number of tillers 354.10 m 2 tillers, area of flag leaf 40.19 cm 2 , spike length 9.89 cm, number of spikes 288.93 m 2 and yield 4.27 tons ha −1 . The results also indicated that the increase in salinity level led to a decrease in the characteristics of plant height 82.22 cm, number of tillers 319.43 m 2 tillers, area of flag leaf 39.93 cm 2 , spike length 9.19 cm, number of spikes 260.13 m 2 , and yield, which amounted to 3.86 tons ha −1 .
