Study of nitrogen influence to productive characteristics of natural meadow type Agrostietum vulgaris was done at locality Vrbica near Berane (830 m a.s.l.), Montenegro, during the period of 2002-2003, by application of following fertilizing variants: 0, 30, 60, 90, and 120 kg N/ha. Results of two years examinations demonstrated that the fertilization with nitrogen have had great impact to yield extent of hay and raw proteins, as well as to changes in floristic composition of lawns. The highest hay yields (5.34 t/ha) and raw proteins (546.3 kg/ha) have been achieved by fertilization with 120 kg/ha, but the greatest effect of applied nutrient to yield increasing was in variant with 90 kg N/ha. Portions of grasses and green in overall yield of the lawns have grown with increasing of fertilizer dose.
