Growth, yielding, leiocaroposide content in goldenrod (Solidago virgaurea L. ssp. virgaurea) herb depending on different NPK fertilisation level were analysed and compared in the study. Every year, before the beginning of plants vegetation the following compounds were applied, respectively: nitrogen fertilisation - in form of ammonium nitrate 34% N (N1 - 0.046 g N per pot, N2 - 0.093 g N per pot, N3 - 0.139 g N per pot), phosphorous in a form of single superfosphate 7.9% P (PI - 0.213 g P per pot, P2 - 0.428 g P per pot, P3 - 0.854 g P per pot) and potassium - in a form of potassium salt 48.1% K (Kl - 0.169 g K2 per pot, K2 - 0.337 g K per pot, l<3 - 0.675 g K per pot) according to experiment design in three levels and different combinations (16) of elements mentioned above. Mineral fertilization is the factor which significantly affected appearance and all golden- rod features under study. Fertilization with use of all macroelements (N, P, K) (especially in double or triple doses) led to the highest level of yields of raw material. Phosphorous played an important role in goldenrod plant proper growth as well as active substances accumulation while nitrogen application took place in aboveground parts of yield.
