Effect of soil medium amendment on chemical composition and digestibility of Lolium multiflorum Lam.
Summary.

The aim of this study was to determine the effect of used soil medium amendment on the background of mineral fertilizers and on the chemical composition, and digestibility of dry matter of Lolium multiflorum Lam. (‘Gaza’ variety). Experiment with the cultivation of this species was carried out in the rings of polyurethane, in four replications. For each of the pots, eight ryegrass seeds were sown. After seeds germination when seedlings reached the two-three leaf stage, negative selection was made by removing the four weakest plants and then experimental factors were introduced in the form of the following combinations: NPK – mineral fertilization in annual doses of 0.6 g N, 0.25 g P2O5 and 0.9 g of K2O per ring, B-NPK – without fertilization, UG – soil medium amendment in the form of 0.25% solution and a dose of 3.7 cm3 per ring, B-UG – without soil medium amendment. Nitrogen fertilization (34% ammonium nitrate) and potassium (60% potassium salt) were used in three doses, and phosphorus (46% TSP) in a single dose in spring. The soil medium amendment solution was used for watering plants in a phase of shooting. The full period of this experiment was in 2009-2010. During this time, the analysis of chemical composition of dry matter yield was performed for all cuts at the Institute of Technology and Life Sciences in Falenty. The using of soil fertilizer in cultivation of ryegrass led to increase the crude ash content, expand the sugar-protein ratio and slight improvement of dry matter digestibility of the tested plant material.

Key words: elephant ryegrass, soil medium amendment, chemical composition, digestibility
