In this study nitrogen (N), Phosphorus (P) and potassium (K) analysis were carried out during vegetative and generative growth periods in some members of Amaryllidaceae family collected from the Central and East Black Sea Regions, on the north of Turkey. The above ground parts of plant were found to have higher macro- element concentrations as compared to below ground parts during vegetative growth period. However, below ground parts have higher macro-element concentrations during generative growth phase due to "top senescence". In addition to this there were significant and mostly negative correlations between plant and soil macro-element concentrations.
