  1. • **Significant at P ≤ 0.01, *Significant at P ≤ 0.05, ns: No significant difference.
  2. Nutrients concentration of white rice was evaluated after nano chelated iron fertilizer application. Nutrients concentration analysis of white rice demonstrated that nitrogen, phosphorus and potassium responded to nano chelated iron fertilizer significantly.
