Abstract: A field experiment was executed on two wheat varieties (Sakha 93 and Giza 168) grown in clay loam soil under limited water condition at the agricultural experimental station of National Research Centre, Shalakan, Kalubia Governorate, for improving water stress tolerance of wheat plant, using a reflectant (MgCO3), during plant growth. Water shortage had a drastic effect on plant growth, yield and nutrient content, however reflectant treatment under limited water condition and different cultivation methods (ridges, drilling and hills) at milky and maturity stages showed great variations. It was proved that reflectant application increased plant yield to match with normal irrigation condition although growth parameters and nutrient contents did not show a clear significant improvement. Sakha 93 wheat variety surpassed Giza 168 in resisting water stress. The drilling cultivation method surpassed ridges and hills, also a clear increase in K+ content was observed in cultivation under water shortage condition and reflectant application.
