Influence of fertilization rates on species composition, quality and yields of the meadow fodder

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 (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 variants are significant at 95% level.
