The effect of sowing quantity and row spacing on seed production of few minor grass species

A wide range of seed material from different grass species is necessary to keep high quality grasslands  and to create buffer zones between  arable lands  and forest  and to recultivate waste or fallow land. Therefore, the aim of our research was to describe elements of seed propagation of some minor grass species.  On the basis  of field  experiments,  different  spacing and  seed quantities  were investigated for Beckmannia  eruciformis, Cynosurus  cristatus  and Elytrigia elongata  aiming at an optimal seed production. Satisfying seed yields were obtained even at a reduced (50% to 75%) amount of seed quantity,  as compared  to theoretical (or normal) values,  calculated  on the basis  of number of plants per area unit.
