Assessing Soil Quality, Wheat Crop Yield, and Water Productivity under Condition of Deficit Irrigation.

Wheat is one of the most important cereal crops in Egypt and all over the world. Its productivity is adversely affected by drought due to deficient irrigation to provide nutrients required for plant growth. In a field experiment, silicon foliar applications at concentrations of 0, 200, and 400 mg L were performed at different irrigation rates ranging from 1000 to 4000 m ha to assess water irrigation productivity and wheat crop yield in a calcareous soil under arid climate conditions.
