Study of Zinc effects on quantitative and qualitative traits of winter wheat in saline soil condition

An experiment was conducted to optimize consumption of Zinc and evaluate of Zinc
effects on quantitative and qualitative traits of winter wheat under saline soil condition.
It was done by three replications in randomized complete block design. The experiment
had four treatments as Control without Zn, 40 Kg.ha-1 Zn as ZnSO4, 80 Kg.ha-1 Zn as
ZnSO4 in soil and 120 Kg.ha-1 Zn as ZnSO4 in soil. Eleven parameters including
quantitative parameters and qualitative ones were measured. The highest grain yield
(4355 Kg.ha-1) and highest Zn concentration in seeds (39.1 mg.kg-1) obtained by using
of 120 Kg.ha-1 Zn as ZnSo4 as soil application. Seed protein content was affected by use
of Zinc and significantly increased. The fourth treatment had a significant difference in
compare to first and second treatments but didn’t a significant difference compared to
third treatment. Results showed that protein content in seeds was affected by using of
Zinc Sulfate and significantly increased. Use of Zinc Sulfate had not any effects on
straw, ear per square meter, number of seed per ear and concentration of Fe, Mn and Cu
in seeds. Totally, use of 80 Kg.ha-1 Zn as ZnSo4 in soil was recommended to obtain
highest grain yield with high quality in saline condition.
