Barley (Hordeum vulgare var. Varde) grown in zinc-polluted soils with variable levels of Zn, Mn, and Fe showed no marked differences in the yield attributable to these variables in both soils investigated. However, in direct contrast to results reported by other investigators, concentrations of /sup 65/Zn and total zinc were found to increase with increased levels of added Mn and/or Fe with few exceptions. Similarly, concentrations of /sup 54/Mn and total Mn also increased with increased levels of Zn and/or Fe. The effects of Zn and Mn on the concentrations of /sup 59/Fe and total Fe were inconsistent. The concentration of Mo was found to decrease with increased levels of Zn, Mn, and Fe and the decrease was more pronounced in one soil than in the other. Although concentration of Cu also showed a slight tendency to decrease with Zn, Mn, and Fe application, the results were inconsistent in both the soils. In general, labelled nutrient elements were more mobile in barley plants than corresponding soil-derived nutrients as evident in the relative percentage distributions between roots and tops. The percentage distributions of Zn, Mn, Fe, Mo, and Cu between roots and tops was apparently not affected by the presence of their interacting ions. The effects of Zn on Mn distribution and that of Mn on Mo distribution, were, however, noticeable. It is concluded that though Zn, Fe, and Mn ions in barley appear to have limited influence on translocation within the plant, these ions exert strong synergistic effects at the site of transport. There appeared to be pronounced antagonism between Mo-Zn, Mo-Fe, and Mo-Mn, in the metabolism of barley.
