Przydatność Festuca pratensis i Trifolium pratense do podsiewu łąki na glebie organicznej
Abstract
Studies were carried out in 2003–2007 on the meadow with the community of
Festuca rubra, on the rot soil proper. In the meadow experiment two factors were studied – the
dose of nitrogen (0, 60, 120, 180 kg · ha–1) and the grass-leguminous mixtures of seeds, with
different participation of Festuca pratensis and Trifolium pratens1
e (1 – without sowing – control,
2 – Festuca pratensis – 100% – 30 kg · ha–1), 3 – Festuca pratensis – 70% + Trifolium pratense – 30%,
4 – Festuca pratensis – 50% – Trifolium pratense – 50%, 5 – Festuca pratensis – 30% +
Trifolium pratense – 70% 6 – Trifolium pratense – 100% – 18 kg · ha–1). Analysis of the floristic
composition of sward showed that the proportion of Festuca pratensis increased when seed
quantity and nitrogen dose were enlarged, but there was no such regularity in the case of
Trifolium pratense. Its share declined independently of the factors of the experiment in the
subsequent study years. Between used combinations of experimental factors, the most
productivity in terms of dry matter yield were objects sawed with mixture – 70% Festuca
pratensis and 30%, Trifolium pratense and Trifolium pratense alone, fertilized with nitrogen
doses of 120 and 180 kg · ha–1. Feed of individual objects characterized by similar chemical
composition. The concentration of majority of analyzed elements (N, P, K, Ca, Mg, and Cu, Zn,
Fe, Mn) corresponded to the level recommended for a good feed. Only the content of zinc and
copper fluctuated below the norm, but phosphorus and potassium – it greatly exceeded.
