The objective of this study was to evaluate the effects of seed treatment with zinc in zinc content and storability in seed as well as the components of yield of crops whose seeds were coated with doses 0, 1, 2, 3 and 4mL zinc sulfate (ZnSO4 kg-1) more fungicide, polymer and water, then were stored for six months in the environment without control of temperature and relative humidity. Before sowing the seeds were evaluated by germination test, and yield components were evaluated: number of spikelets per plant, number of grains per spikelet and grain weight per plant. After storage for six months assessed the zinc content in the seeds. The zinc coating shall not affect the viability of wheat seeds stored for six months, and further increases in the number of grains per spikelet and grain weight per plant. The zinc content in the seeds increased linearly with increasing doses of ZnSO4 via seed coating.
