For this aim we used three different corn genotipes, five differentphosphorus levels and three different zinc levels. Phosphorus and zinc levels of plantswere determined. For our results, if the phosphorus level increase in the soil, plant?szinc uptake is effecting negative. Also if the zinc level is increase in the soil,phosphorus uptake of plants is effecting negative.Key Words: Phosphorus, Zinc, Phosphorus and zinc interactions, Corn.II
