Study of meadow grass biology were started already in the thirties. After the second world war number and range such kind of studies had increased systematically and their methodology had been improved. The studies were carried out in the control conditions and as field experiments, in pure stands and in mixtures, in specialist as well as in practical experiments. The results obtained have allowed to explain many occurrences which took place in the applied studies and they affected improvement of rational management of grassland and helped in valorisation and characterisation many of grass species. Continuation of grass biology studies is necessary but in complex way and in co-operation with different branches of basic sciences using modern equipment and unify methods of studies.
