Abstract
This research was carried out in Tekirdag, Turkey during 2003 in order to determine the effects of increasing nitrogen and zinc fertilizers on the iron, copper and manganese content of maize plant in calcareous and zinc deficient soils. For this purpose sandy calcareous and clay calcareous soils were used in this research. The experiment was done greenhouse conditions with three replications and maize was grown. Three different doses of N, N0 N1 and N2 (0, 50 and 100 kg N ha-1, respectively) were applied to each pot as NH4NO3. Four different doses of Zn (Zn0 0; Zn1: 5; Zn2: 10 and Zn3: 20 mg kg-1) were applied to each pot as ZnSO4.7H2O. According to the results, dry matter amount of maize plant increased with increasing of N and Zn doses. Iron, Cu and Mn contents of maize plant decreased with increasing of N and Zn application doses. Increasing in dry matter amount and decreasing of Fe, Cu and Mn contents of maize plant were determined as statistically significant at the level of 1%.
