The influence of extensive and intensive use of permanent meadow community on the quality of forage and qualitative production
Original language description
The results relating to the influence of various levels of N+PK fertilization (without NPK, P30+K60 kg.ha-1, N90+PK kg.ha-1, and N180+PK kg.ha-1) prove a marked decrease of N-substances, PDIN (protein supplied when nitrogen is limited in the rumen) and PDIE (protein supplied when energy is limited in the rumen) concentrations in the forage of sward without N-fertilization, and also with the application of low N90+PK kg.ha-1 amount as compared with the intense level of N-fertilization variant, i.e. 180 kg.ha-1. With other nutrients (fibre, NEL -- Netto energy of lactation) no significant differences were ascertained. The influence of intensity of utilization had a marked influence on the increase of all nutrient concentrations with variants comprising 3to 4 cuts in comparison to both variants of the use in 2 cuts (early and late first cut). For an objective evaluation it is necessary to carry out an assessment of the interactive influence of fertilization and intensity of use.
