An experiment was conducted in the experimental field of Seed and Plant Improvement Institute in Karaj for three consecutive cropping seasons, 2001-2003, to study the effects of eight different fertilizer treatments including some microelements on grain yield and protein content of a bread wheat cultivar Pishtaz. The experiment was in a RCBD with three replications.Eight fertilizer treatments were: NPK (control), NPK-An, NPK-Fe, NPK-Mn, NPK-Zn, NPK-Fe-Mn, NPK-Mn-Fe, NPK-Mn-Zn and NPK-Fe-Mn-Zn. To provide the experimental treatments, 10 kgh-a Secostrin 138, 40 kgha-1 Sulphate of Zinc, and 30 kgha-1 Sulphate of magnesium were added to NPK. Based on the results, the highest grain yield was obtained from the NPK-Fe-Mn-Zn treatment with a yield increase of 900 kgha-1 comparing with the check treatment (NPK). Other treatments with different microelements also caused increase in yield. Protein contents of grains obtained from the treatments containing Zn + Mn, Zn and Mn increased by 5.2, 4 and 3.2 percent, respectively.
