In the present study potassium treatment resulted in increased nitrate reductase activity of Cicer arietinum plants, the increase being greater in the treatments where potassium was used as KNO3. Light-stimulated increase in NR activity was obvious in all the treatments. Analysis of the plants supplied with added potassium exhibited greater potassium content and slightly reduced magnesium contents. Accompanying anions showed an impact on uptake of potassium. Potassium supplementation also led to depletion of nitrogen in the medium, probably as a consequence of improved nitrogen utilization.
