Wplyw ilosci wysiewanych nasion na plonowanie upraw nasiennych Lolium perenne

A two factor field experiment in split-plot design was carried out in the years 1996-1999 on a good rye complex in Agricultural Experiment Station Lipki near Stargard Szczeciński. In the experiment two cultivars were considered: ‘Arka’ (fodder cultivar) and ‘Niga’ (lawn cultivar) and four seeding rates (10, 13, 16 and 19 kg ha⁻¹). Detailed research included biometrics measurement and seed yield. The experiment was set up in spring with seeds bcing sown into spring barley as a companion crop harvested for seeds. The obtained results of seed yield show that their value depends on the year of utilisation. The morphological character of plants is also in great part modified by the studied factors .
