Abstract

A pot experiment was applied to investigate the effect of different amendments on some properties of sandy soil and its productivity of wheat plants. Three-factors computer model were implemented, X1 (cheese whey + super absorbent Polymer (SAP)), X2 (biochar + SAP) and X3 (compost+SAP). Some physical and chemical properties of sandy soil and wheat yield were estimated. The obtained results appeared that the values of bulk density, real density, porosity and moisture content (field capacity, FC, wilting point, WP, and available water, AW) of the tested soil were positively influenced by the applied soil amendments. The maximum AW was increased till 8.11% with application of 10, 10 and 80% of (cheese whey +SAP), (biochar + SAP) and (compost +SAP), respectively. Significant increases in wheat yield, were observed due to amendments addition. All the wheat growth characters showed an enhancement by the application of soil amendments as compared to the control. The maximum wheat grain yield was recorded with the application of (cheese whey+ SAP), (biochar+ SAP) and (compost+ SAP) at a rates of 10, 10 and 80%, respectively. This increase was 0.84 ton fad.-1 in comparison with the control.
