How much Zinc application in salinity condition affected the yield and concentration of Zinc in Wheat?

In order to investigate the influenceof Zn levels in soil salinity conditions on the yield and Zn concentrationin different parts of wheat (Trictiumaestivum), a study was conducted with three levels of salinity (2.7, 6.4, 10.2 dS.m-1), four levels of Zn (0, 10, 20 mg Zn/kg soil and foliar application) and two wheat cultivars (Ghods and Atrak) in the form of factorial and completely randomized design with three replications. The results showed that the salinity led to a decrease in all of the parameters of the two wheat cultivars. Land application of Zn with the concentration of 20 mg.kg-1 resulted in an increase in the yield of shoots and grain.The lowest and highest protein percent in every salinity and Zn treatment belong to Atrak and Ghods cultivar, respectively. As the application of Zn increases, the concentration of Zn in the shoots and grain increased significantly. The results suggested that addition of Zn in the conditions of low to medium salinity can improve the growth and finally the wheat yield through decreasing the effects of salinity. Atrak cultivar has more endurance potential in salinity conditions than Ghods cultivar
