The research was aimed at assessing the biomass yield of Festulolium braunii and its
content of raw protein and crude ash after application of slurry, both on its own and together with
soil conditioners (UGmax and Humus Active), and mineral fertilizers. The studies were
conducted on the basis of a two-year field experiment. The interaction between slurry and soil
conditioners and between slurry and mineral fertilizers was studied on the Sulino variety of
Festulolium braunii, a hybrid between Lolium multiflorum and Festuca pratensis.
Compared with plants treated with liquid manure on its own, slurry applied with soil conditioners
and mineral fertilizer did not significantly increase the biomass yield of the grass. However, there
was higher protein content in Festulolium braunii, even if statistically insignificant, as a response
to slurry supplemented with mineral fertilizer than in plants treated with slurry only. Various
forms of treatment did not differentiate crude ash content in plant dry matter in a statistically
significant way.
