The feed value of Festulolium braunii mixtures with red cloverand alfalfa supplied with soil's fertilizer

The experience with growing of Festulolium braunii (Felopa variety) in mixture with red clover – (Tenia variety) and alfalfa (Tula variety),was founded in April 2007, in randomized blocks in 3 licants on the experimental. The first experimental factor were 3 grass – legumes mixtures with the following composition: M1 – Festulolium braunii (variety Felopa) 50%, Trifolium pratense (Tenia variety) 50%, M2 – Festulolium braunii (Felopa variety) 50%, Medicago sativa ssp. media (Tula variety) 50%, M3 – Festulolium braunii (variety Felopa) 50%, Trifolium pratense (Tenia variety) 25%, Medicago sativa ssp media (Tula variety) 25%. The second experimental factor was soil’s fertilizer, applied in the phase of grass earing at a dose of 0.9 l ha–1 diluted in 350 l of water. Combinations with soil’s fertilizer were marked as UG, and without soil’s fertilizer BUG. The specific studies were included the total protein content, sugars, fiber (% DM) and dry matter digestibility (%). Analysis of plant material, in regards those characteristics, were done at the Institute of Technology and Life Sciences in Falenty. The obtained results showed that application of the soil’s fertilizer to undepend on the type of mixture and study years caused the, increase of the crude fiber content and sugar-protein ratio and decrease of dry matter digestibility of analyzed plant material
