Effect of different management on the yields, forage quality and botanical composition of permanent grassland
Original language description
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%).
