Wartość RFV mieszanek Festulolium z koniczyną łąkową i lucerną mieszańcową zasilanych użyźniaczem glebowym

The aim of this study was to determine the effect of soil’s medium amendment and qualitative and quantitative composition of Festulolium mixtures with legume plants on the relative feed value of the obtained feed. Experimental factor were three grass-legumes mixtures. Another factor was the soil’s medium amendment, applied at tillering stage of the grass in a dose 0,9 l ha–1 diluted in 350 l of water. Combinations with soil’s medium amendment were labeled as UG, and without soil’s medium amendment as BUG. The study included chemical composition of dry weight of plants, which were determined at the Institute of Technology and Life Science in Falenty. The obtained results were used to assess the quality of feed from mixtures, which was conducted by Linn and Martin test. Classification parameter was the relative value of feed – RFV. The best feed material was collected from the sown by objects Festulolium braunii in mixture with red clover. The using of soil’s medium amendment to grow, regardless of the mixture, cut and a study year, resulted in a increase of relative feed value of estimated mixtures.
