Abstract:
Considering the importance of iron (Fe) Ni and that Fe deficiency is one of the main nutritional problems of the Iranian people's this study was carried out to investigate the interaction effect of Ni×Fe on concentration and uptake of Ni and Fe by corn plant (Zea Mays L). A greenhouse experiment was conducted within the framework of factorial randomized complete block design (RCBD) in a calcareous soil with Ni treatments at four levels (0, 10, 50 and 100 mg Ni kg-1 soil) from Nickel sulfate (NiSO4) (Merck Co.) and Fe from FeSO4 and FeEDDHA in five levels of (0, 10 and 20 mg Fe Kg-1 soil), according to two source on corn plant (single cross 704). After 90 days, plants harvested and Ni and Fe concentration of shoot and root were measured. According to the results, with increasing applied Ni levels, shoot Ni concentration significantly increased at levels 10, 50 and 100 mg Ni Kg-1 soil, respectively, 18.78%, 41.106%, 97.116% compared to the control. With increasing applied Ni levels, root Ni Concentration increased respectively, 1.27, 4.63, 9.18 compared to the control. With increasing levels of applied Ni in the soil, Fe concentration of root significantly (p
