This study investigated the impact of different rate of nitrogen nutrition on soybean seedling tolerance to cadmium treatment. Soil contamination with cadmium has become a serious issue in sustainable agriculture production and food safety. The results indicated common response of soybean seedlings to cadmium treatment such as stunted root growth and increased level of lipid peroxidation. However, a defense reaction was observed under combined seedling treatment with cadmium plus nitrogen. Interaction of cadmium and nitrogen resulted in decreased cadmium uptake by seedling roots that were cultivated at a high nitrogen nutrition level. The obtained data confirms the complexity of plant non-specific defense responses to abiotic stressors and may be used for optimization of plant nitrogen fertilization on cadmium contaminated soil.

Key words: cadmium, defense reactions, Glycine max, nitrogen fertilization, soybean.
