Abstract
A field experiment was carried out on sandy soils located at south of El-Qantara East station, North Sinai, Egypt. The study aimed at investigating the effect ceramic waste dust (CWD) or farmyard manure (FYM) on some soil's physical and chemical properties and the yield of cultivated wheat. The treated materials were used at the rates of 0, 25, 50, 100 and 150 Mg ha-1. The obtained data revealed that soil pH, EC, bulk density, penetration resistance, and hydraulic conductivity decreased with increasing application rates of either CWD or FYM, while, the OC, maximum water holding capacity was increased. The obtained results showed that wheat grain yield increased with increasing either CWD or FYM at rates up to 150 Mg ha-1. The average yields were 1.61, 2.79, 4.28, 6.28, and 7.65 Mg ha-1 for CWD addition rates of 0, 25, 50, 100, and 150 Mg ha-1, respectively. While, they reached 1.61, 2.71, 3.84, 4.87, and 6.10 Mg ha-1 for FYM additions at the same rates, respectively. Statistical analysis showed that a quadratic function fitted the relationships between CWD, FYM rates, and wheat grain (r = 0.99** and 0.99**, respectively). Differential’s method of the quadratic equation obtained was used to find the predicted values of a critical level of rate amendments which were 239 and 221 Mg ha-1 for CWD and FYM, respectively.
