The aim of the pot experiments was to determine the effect of different doses of nitrogen fertilization on three soil materials (sandy, silty and organic - peat moss) on the growth, development, and yield of goldenrod. The best parameters of growth and the highest yield of herb (independently of fertilization) were obtained on organic soil material, and the lowest on sandy one. The highest content of biological active compounds, however, was found in the herb grown on sandy soil material. A significantly lower content of leiocarposide was found on silty, and especially organic material. In the case of flavonids a significantly lower content was observed on silty materia, while it was similar on the remaining soil materials. Independently of the soil material, along with increasing nitrogen fertilization, an increase was observed in yields and active compounds (both flovonoids and leiocarposide) accumulation
