Effect of long-term fertilization on the floristic composition of the meadow stand fodder yields

Original language description

The experiment concerning the study of botanical composition of stands and yielding abilities was founded in 1966 y. The variants of fertilization for the evaluation: 0 - P40 K100 - N100 P40 K100 - N200 P40 K100. The significant reduction of the speciesdiversity was found in the nitrogen fertilization. Alopecurus pratensis L. was the most infested plant belonging to the rhizomatic species in both fertilization levels in the years 1971-1980 (80-86 % D). According to the nutrition level in long-term studies in 1966-2000 the mean yield was found in the check variant i.e. 4.97 t/ha of hay. The variant fertilized by P40K100 gave the mean yield 5.53 t/ha. In the nitrogen fertilization 100 kg/ha (+ PK) the mean long-term yields of dry mass were 7.29 t/ha. Inthe variant 200 kg N/ha (+PK) the mean yields was 8.53 t/ha.
