Resumo: | The element zinc (Zn) is considered an essential micronutrient to plants, being that the addition of this metal in forage cultivation may cause increment in the productivity. In Brazilian soils are frequent the cases of Zn deficiency, being necessary the fertilization of these areas with this micronutrient. However it must be highlighted that some sources of this micronutrient available in the market present in its composition heavy metals. This work aimed to study the effect of different sources and doses of Zn applied in Tifton 85 and the production of dry matter and the levels of Zn, phosphorus (P), cadmium (Cd), lead (Pb) and chromium (Cr) in leaf tissue and the levels Zn, Cd, Pb and Cr in soil. The experiment was conducted in a greenhouse using a Rhodic oxisol of medium texture. Vases with volume of 4 dm3 were used, which were organized in a completely randomized in factorial scheme (5x4) with three replications. The treatments were the five sources of Zn (A, B, C, D) in four doses of the micronutrient (0, 2, 4, 6 kg ha-1). The results show that did not occurred accumulation of Cd, Pb and Cr in the leaf tissue and Cd and Cr in the soil. The source E provided higher production of dry matter in relation to the sources A, B, C, D. However the source 'A' provided higher concentrations of Zn for the forage.
