چکیده:
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.

Sharma and Yadav (1999) reported that Zn uptake decreased by increasing in grain increased by adding Zn to saline soils.
Chipa and Lal (1986) reported that use of extra application of Zn is necessary to avoid decreasing of low uptakes of micronutrient caused by salinity.
(view the image of this page) Data showed that the grain yield, ear length, 1000 seed weight, seed protein content and Zn concentration in seeds were significantly affected by Zn application.
Conclusion Data indicated that some parameters such as grain yield, 1000 seed weight and ear length were increased by use of Zinc (Figures 1 and 2).
Khoshgoftarmanesh et al (2001) reported that use of Zinc in saline condition increased salt tolerance in wheat and yield.
Data of table 3 indicated that grain yield, 1000 seed weight and ear length were increased by increasing application of Zn. It has been shown that Zn use efficiency in saline soils was low, caused by land leveling, lime and deficiency of organic matters and there weren’t any effects by low using of Zn fertilizers in saline condition.
