ABSTRACT

Three microplot trials with spring wheat were run on soil varying for pH level. Increasing Zn doses from 5 to 200 mg·kg ^-1 were tested. Zn applications resulted in a substantial rise of Zn content of wheat shoots. In addition, an interaction of zinc and phosphorus in the plants was found. Contrary to most reports in literature, the interaction was not solely an antagonism. It is only the excessive doses of zinc that restricted phosphorus uptake and lowered the concentration of that element in wheat shoots. Instead, with poor phosphorus supply to the plants moderate zinc doses stimulated phosphorus uptake and raised phosphorus content of plants. Zinc application rate and phosphorus status of plants had a greater impact on Zn-P interaction than did soil pH.

Key words: zinc, excess, phosphorus, interaction, wheat.
