✦ Synopsis

Physiologically inactive zinc occurred in the tops of both 'zinc-inefficient' and 'zinc-efficient' maize cultivars when grown in pots on a black earth soil. The condition was not caused by P/Zn, Fe/Zn, Cu/Zn or Mn/Zn imbalances, but was associated with marginally deficient boron levels. Phosphorus fertilization intensified the condition producing a P/Zn imbalance in both cultivars, possibly combined with a Cu/Zn imbalance in the 'inefficient' cultivar and Fe/Zn, Cu/Zn and Mn/Zn imbalances in the 'efficient' cultivar. Plant analysis was inadequate as a measure of zinc deficiency under these conditions.
