Effects of Copper (Cu) Application on Concentration and Uptake of Cu, Manganese (Mn), Potassium (K) and Phosphorus (P) on Corn Plant

Copper (Cu) is an essential micronutrient for plant growth. Copper application can have a significant impact on Mn, K, P and other nutrients in plants nutrition. In this study the effect of applied Cu on corn (Zea mays L.) growth, concentration and uptake of Cu, Mn, K and P in 21 calcareous soils was checked out. In order to measure the concentration and content of uptake of the studied elements, in a greenhouse experiment, corn plant (Zea mays L.) single cross 704 variety cultivated in two levels of Cu, zero (control) and 7.5 mg Cu per kg-1 of soil as CuSO4.5H2O. The experiment was carried out as factorial in a randomized complete blocks design with three replications. According to the results, by application of copper, corn shoot dry weight, shoot Cu concentration and uptake and root Cu concentration were significantly increased (p
