Popis:	The objective of this study was to evaluate the effect of seeding treatment to zinc application as regards the nutrition and production of dry matter in maize plants. The experiment was conducted under greenhouse conditions, with completely randomized design, arranged in a 2 x 5 factorial and three replications. The treatments corresponded to two maize cultivars, the BRS 1001 and the PZ 677 and five rates of zinc (0, 25, 50, 100 and 200 g of Zn to 20 kg of seeds) as zinc sulfate. The effect on the outgrowth speed was followed after 28 days of sowing and the dry matter production and the zinc level in the leaves and roots were evaluated. There was accumulation in the level of zinc in the leaves and roots with an increase of the rates. However, a significant increase in the dry matter production was not observed. The plants did not present toxicity symptoms with the rates used.
