The influence of extensive and intensive use of permanent meadow community on the quality of forage and qualitative production

Popis výsledku v původním jazyce

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.
