A field experiment was carried out at research station of Field Crops Department at College of Agriculture at Tikrit University, which is about 12 km from the center of Tikrit city, during two winter agricultural seasons 2021-2022 AD and 2022-2023 AD. The experiment included two factors: first was ten varieties of six-row barley, which were Warka Aswad, Shu`a, Al Khair, Hadar Aswad, Amal, Buraq, Samir, Rayhana, Arifat, and Ibaa 99, and second was three spray concentrations of zinc, namely (0, 60, and 120) mg. L. The experiment was applied according to a Randomized Complete Block Design (R.C.B.D.), with three replications and in a split-plot arrangement and following results were reached: Erivat variety excelled in recording highest arithmetic means for protein percentage (12.55%), while Hadhrat Aswad variety recorded highest arithmetic means for fiber percentage trait (11.493). )% and percentage of zinc (20.000)%, and the third concentration exceeded 120 mg.L in giving highest means for percentage of fiber (11.660)%, the percentage of protein (12.466)% and percentage of zinc (14.350)%, whereas second season gave highest averages for percentage of fiber (10.467) % and percentage of protein (11.922)% and the percentage of zinc (13.145)%.
