Abstract

The aim of this study was investigate the effects and interactions of iron and manganese levels on the yield of corn (caltivare 610 Musil Hungary) took place. Treatments included four levels of soil application of Fe 0, 10, 20 and 30 mg of iron per kilogram of soil from the source of FeEDDHA and four levels of soil application of manganese 10, 20 and 30 mg per kg soil from source of MnSO4. 4H2O that arranged as factorial randomized complete block design with three replications were studied. Plants were grown in greenhouse condition and in a soil with silty loam texture and then after full growth and necessary tests on the soil and dry matter was conducted. The results showed that by using the concentrations of 20 and 30 ppm iron, manganese uptake by corn has been increased (p≤0.05). On the other hand, use of manganese in all concentrations reduced the absorption of iron, which these effects were not significant. In addition, Iron application up to a concentration of 20 mg per kg increased leaf and stem growth but for root it was not significant. The results showed that manganese has not a significant effect on the growth of stem and root of corn.
