Resumo: | The zinc (Zn) application of adequate form favors the growth of the plants, however, in high rates can diminish the yield of the pasture. Thus, it was objectified to evaluate the effect of the Zn application in the nutrition, growth and production of grass Panicum maximum cv. Megathyrsus, was realized  an experiment in conditions of house of vegetation with six rates of Zn: 0; 15; 30; 60; 120 and 360 mg dm-3, made use in fully randomized, with four repetitions. To the 45 and 75 days after the emergency of plants evaluated it height, the number of leaf, the number of tillers, the mass of dry substance of aerial part, the concentration of Zn in the soil, the content and accumulation of Zn in the plant. The zinc application increased its concentration in the soil and your content in the plant, the number of tillers and dry mass of the aerial part, however, didn’t affect the height and the the number of leaf of the grass-megathyrsus. The grass-megathyrsus presented high tolerance the high rate of zinc, having excellent production of dry substance, in first and second cut, respectively, with zinc concentration in the soil of 32 and 37 mg dm-3 and in the part area of 211 the 243 mg kg-1. The toxicity of Zn is associated with the concentration of Zn in the soil of 43 mg dm-3 and content in the aerial part, for first and second cut, respectively, of 279 and 303 mg kg-1 of Zn.
