ABSTRACT
The aim of the work was to determine the nutrient content in Miscanthus and the value of nutrient uptake from the soil under different environmental conditions. The research was carried out in 2004-2006 in the eastern part of Poland at two experimental stations. The three-year average yield of Miscanthus oscillated between 15 and 17 t·ha-1·yr-1. Nitrogen content in shoots varied between 0.22 and 1.23%, whereas the phosphorus content in shoots was between 0.01 and 0.08%, and potassium content in shoots was from 0.16 to 1.11%. The differences depended on the localisation and year. Nitrogen uptake by the plant was between 49 and 216 kg·ha-1, whereas the phosphorus uptake oscillated between 3 and 28 kg·ha-1, and potassium uptake was from 37 to 275 kg·ha-1. The differences depended on the localisation and year.
Key words: Miscanthus, nitrogen, nutrient uptake, phosphorus, potassium.
