Two field experiments were conducted at Meet Loza. Mansoura. Dakahlia Governorate during 2003/2004 and 2004/2005 seasons to study the effect of three levels from ammonium nitrate fertilizer with and without Ca + Mg addition on wheat plant characteristics and yield component as well as macro and micronutrients. Results showed that: 1.. Plant height. leaf area. spike length. grain and straw yield were increased with increasing nitrogen rates under Ca + Mb sulphate addition. 2* N. P. K. Ca. Mg. Fe. Zn and Mn content of grains were increases with increasing the rates of nitrogen in presence of Ca + Mg addition and these increase were significant. Its conclusion that. addition of calcium and magnesium sulphate increased the availability of macro and micronutnents for wheat plants and using 75 kg N fed“ with Ca + Mg were the best treatment for most parameters.
