Abstract

Effects of different N, P and K supply levels as well as their combinations on the development, yield and species composition were studied in an experimental hay field created by a mixture of eight grass species without legumes, having Meadow fescue (Festuca pratensis) as the main component, within the frame of a 39 year old long-term mineral fertilization experiment, in 2012. The soil contained 3% humus, 3-5% CaCO3 and 20-22% clay in the ploughed layer, and was originally supplied moderately with N and K and poorly with P and Zn. The experiment included 4N×4P×4K = 64 treatments ×2 replications = 128 plots altogether. The groundwater was at a depth of 13-15 m and the area was prone to drought. In the studied year 2012, the area received 123 mm rainfall before the harvesting (7 June). The grass developed insignificant amount of biomass after the first harvest in the 12th year, therefore the second cut was omitted. The results showed that the N, N×P and N×K fertilizations considerably increased the competitive ability of grass species against weeds and legumes in the 12th year of the mixed-grass hay field experiment. Among fertilizers the N treatments proved to be the most effective considering either grass cover ratio or stand height or hay production. Under extreme N×P×K supply conditions (treatments) the following minimum-maximum values were detected in the plots: 10-70 cm for stand height, 40-58% for fresh per dry biomass, 1.4-9.8 t·ha-1 for green cut biomass and 0,6-4,8 t×ha-1 hay biomass. Legumes appeared almost exclusively in the N-control plots only. In the fora of the 128 plots, altogether 8 grasses, 6 legumes and 39 non-leguminous dicots were identifed. Among the 8 grasses sown 12 years ago Agropyron pectinatum and Festuca arundinacea maintained considerable cover and further two Dactylis glomerata and Phalaris arundinacea proved to be persistent although their cover did not exceed 1%. In addition, Bromus inermis, as a spontaneously appearing grass, attained 14.3% cover in average.
