Poa chaixii (broad-leaved meadow grass) is a poorly known European grass and this, in turn, can be attributed to the fact of its rare occurrence. However, in recent years, a growing interest in many facets of this grass has been observed. The objective of research studies was a better understanding of biological-chemical properties of Poa chaixii which can determine its occurrence and utilisation on lowland areas. Investigations followed two directions: selected biological and chemical properties of this grass. Investigations of its biological properties included: the size and development of generative shoots as well as their seed potentials, plant vitality and response to nitrogen fertilisation. Investigations of chemical properties in our own studies comprised recognition in plants of the quantitative occurrence of organic and mineral constituents important from the nutritional point of view taking into account vegetation and different nitrogen fertilisation.
