The trial was carried out during two years (2005 and 2006) on Agrostietum vulgate - type meadow in the hilly mountainous region near Valjevo (at an altitude 750 m). The investigation included six NPK fertilizer rates (N0P0K0, N50P50K50, N100P50K50, N100P100K100, N150P100K100 and N200P150K150 kg ha-1 yr-1). The increase in N, P, and K fertilization level resulted in corresponding increases in the quantity of grass dry matter. In particular, the increases in N rate had a favorable effect on DM yield. The maximum two-year average dry matter yield of 8.17 t ha-1 was achieved with the highest NPK rate (200:150:150 kgha-1). The increase was 5.94 t ha-1 or 365% compared with the control. DM yield ratio between the highest NPK rate and control was similar in 2005 and 2006 (indices 357 and 377, respectively.) [ABSTRACT FROM AUTHOR]
