The goal of the present research was to study formation of the productivity of perennial ryegrass at different rates of mineral fertiliser use. Field experiments were carried out on Sod-Podzolic soils during 1999-2001. The following mineral fertiliser rates were used: N and P205 each - 0, 30, 60, 90, 120 kg ha*[-1); K20 - 0, 40, 80, 120, 160 kg ha*[-1). The productivity of DM and seeds was dependent on genetic characteristics of the particular variety, on the rates of mineral fertiliser and as well as on the meteorological conditions prevailing in each investigation year. The average DM yield, depending on the particular variety, constituted 2.21-6.07 t ha*[-1), and the average seed yields were 255-672 and 133-400 kg ha*[-1) in 1st and 2nd years of stand uses, respectively.
