Effect of different management on the yields, forage quality and botanical composition of permanent grassland

Popis výsledku v původním jazyce

We investigated the effects of cutting frequency and fertilisation on the dry matter (DM) yield, forage quality and plant species composition of permanent grassland. A plot trial was set up in 2003 at Rapotín. Four levels of cutting frequency (4 cuts peryear; 3 cuts per year; 2 cuts per year; 1 or 2 cuts per year) and four levels of fertilisation (no fertilisation, P30K60, N90P30K60, N180P30K60; pure nutrients) were applied from 2003-2008. The results showed that DM yield was significantly influenced by fertilisation and by intensity of use; the lowest DM yield was found with the 4-cut regime (6.10 t ha-1). Decreasing the cutting frequency reduced the energy value (NEL) to 4.64 MJ kg-1 DM. The redundancy analyses showed that species composition was significantly influenced by intensity of use (9.5%) and time (8.5%).
