Vegetation experiments were conducted in the years 2002-2004, in two specialist horticultural farms. The dynamics of nitrogen, phosphorus and potassium contents were analysed in the index parts of selected anthurium cultivars (Anthurium cultorum Birdsey): Baron, Choco, Midori, Pistache, President, and Tropical. Plants were grown in expanded clay using drip fertigation with standard nutrient solution. Fully expanded leaves after fresh-cut flowers as the index parts for chemical analyses were collected every 2 months over the period of 3 years. A varied dynamic of nutrient contents was found in the index parts of plants. During the 3 years of studies a downward trend was recorded for nitrogen content, while an upward trend was observed for contents of phosphorus and potassium. A cultivar differentiation was shown for contents of the above mentioned nutrients and quantitative proportions between them
