Abstract
Abstract The relationships among Na, K, and Zn in corn ( Zea ma,s L.) nutrition are not well understood. A greenhouse experiment was conducted by growing corn (‘Vijay’) for 45 days as an indicator crop. Treatments were Na (0, 50, and 250 ppm), K (0, 50, and 250 ppm), and Zn (0, 5, and 10 ppm) applied in all possible combinations, and replicated three ames. Sodium decreased shoot dry matter yield K, and Ca concentration, and increased Na concentration. Magnesium and Zn concentrations were not influenced by Na when Zn was applied. Potassium generally reduced the effectiveness of Na and Zn treatments, increased K concentrations, and decreasd Ca, Mg, and Na concentration. Zinc decreased the effectiveness of K and Na treatments, and increased yield, and Zn, K, and Mg concentration. At low levels of K, application of 10 ppm and Zn decreased Na and Ca concentration. A triangular relationship was evident among Na, K, and Zn, depressing each others effectiveness on growth and tissue concentrations. The adverse effect of Na on plant growth was attributed to its antagonistic relationship with Ca, K, and Zn in plants and increased salinity and alkalinity hazards in the soil.
