Interaction Effects of Nitrogen Rates and Forms Combined With and Without Zinc Supply on Plant Growth and Nutrient Uptake in Maize Seedlings.

ABSTRACT: Previous studies have shown that zinc (Zn) accumulation in shoot and grain increased as applied nitrogen (N) rate increased only when Zn supply was not limiting, suggesting a synergistic effect of N on plant Zn accumulation. However, little information is available about the effects of different mineral N sources combined with the presence or absence of Zn on the growth of both shoot and root and nutrient uptake. Maize plants were grown under sand-cultured conditions at three N forms as follows: NO₃ ^- nutrition alone, mixture of NO₃ ^-/NH₄ ⁺ with molar ratio of 1:1 (recorded as mixed-N), and NH₄ ⁺ nutrition alone including zero N supply as the control. These treatments were applied together without or wi
