Abstract :This research has been done in order to determine the deficiency problems of nitrogen, phosphorus and potassi-um which are of main macro plant nutrients and of zinc which is main micro nutrient on maize insert ignore into journalissuearticles values(Zea mays L.);. The results of a two-year-research have shown that the deficiency of nutrient elements has restricted the growth and development of the corn plant in general. But, when the nutrients are compared to each other, it has been seen that on the characteristics of the plant examined insert ignore into journalissuearticles values(plant height, leaf number per plant, leaf width, leaf lenght, the diameter of the stem, fresh stem weight, fresh root weight and the proportion of stem/root); the deficiency of nitrogen has the biggest effect and it has been followed by phosphorus and potassium. The deficiency of zinc has shown differents results. When compared to complete nutrient solutions, the effect of zinc deficiency on plant height, fresh stem weight and the propor-tion of stem/root has been negative; it has been the same on leaf number per plant, leaf width, leaf lenght and the diameter of the stem; and it has been positive on fresh root weight. As a result, as far as the fertilization of corn plant is concorned, the emphasis must be put firstly on nitrogen ferti-lizer, secondly on phosphorus and potassium and then zinc.
