Of minia univ. at shosha –samalute- EL-minia governorate, A.R.E. to carry out the studied field experiments on wheat variety Giza 164. these experiments were conducted at the same season 1995/1996 using three rates of Mg applied to wheat plants in two application methods as follows:
10,15 and 20 kg O/Fed. As foliar spray.
20,30 and 40 kg O/Fed. As soil application.
Also, four rates of k were applied only to the soil as 25, 50, 75 and 100 kg K2 o / Fed.
