Four variants in four replications were studied on permanent meadow stand on Czech and Moravian highlands.The altitude a.s.l.

is 485 m, original growth type was Dactylidetum, association Trifolio-Festucetum rubrae.Four variants: control Shirt (without fertilization), 40 kg P + 100 kg K/ha, 100 kg N/ha (+ PK) and 200 N/ha (+ PK) were evaluated.Botanical analyses of stands were done by the method of reduced projective dominance (D in %).The cut green matter was weighed up, mean samples for dry matter determination and chemical analyses were taken.

Botanical composition of the meadow stand in 1991-2000 was not stabile and was changing due to nourishment.The yields of dry matter ranged within 10 years in the control variant from 1.07-3.42 t/ha (in the plot fertilized by P40K100 2.

09-5.95 t/ha, in the plots with nitrogen (+ PK) 2.29-6.52 t/ha, resp.

3.74-7.61 t/ha).According to the t-test, the yields of dry mass in experimental ngetikin.com variants are significant at 95% level.
