The objective of this study was to evaluate treatment in barley seeds with different doses of zinc in the physiological quality of seeds produced and treated, as well as evaluate the seed yield. The treatments consisted of combinations of two cultivars and six doses of zinc, in a factorial 2 X 6 (Factor A: – cv – BRS Ellis and BRS Cauê; Factor B: levels 0, 1, 2, 3, 4 and 5 mL kg-1 seed), totaling 12 treatments. The experimental design was completely randomized with four replications. The physiological quality of seeds produced was treated and evaluated by tests of vigor and germination, and after harvest were evaluated seed yield. Zinc supplied via barley seeds up to a dose of 5 mL kg-1 seed, the BRS Cauê and Ellis, has no effect on seed germination and vigor of treated and produced, but gives significant increases in seed number and yield.
