| Abstract | ||||
| A pot experiment was carried out at the greenhouse of Agricultural Research Station., Sakha, Kafr El Sheikh Governorate ,during the winter season of 2015/2016 to investigate tolerance of wheat(Triticum aestivum L.) crop to cadmium element and study the effect of N-fertilization (ammonium sulfate, calcium nitrate and urea) on availability of cadmium (0, 40, 80 and 120 ppm) under both clay and sandy soils. The results showed that clay soil was higher than sandy soil in the studied soil and plant traits. The negative effect of the interaction between cadmium and urea more than between cadmium and calcium nitrate followed cadmium and ammonium sulfate. Availability of cadmium led to reduce fresh, dry weight and N % in the straw and grain of wheat plant while increased Cd (mg kg-1) in the straw and grain. The highest values of NH4 and Cd (mg kg-1) in soil were found due to interaction between clay soil, ammonium sulfate and 120 ppm Cd. On the other hand, the highest values of NO-3 (mg kg-1) in soil were found due to interaction clay soil, Urea and120 ppm Cd. | ||||
