Description
The development of botanical composition and primary production was followed from 1993 to 1995 at the southern side of the Jizera Mountains on three-cutting permanent, temporary and slot seeded grassland. Each grassland type was divided into 4 variants with various doses of mineral fertilization. The same clover-grass mixture composed of 5 components were used for the renovation by ploughing and slot seeding. During three years of the observation a very fast drop of the clover portion for the benefit of grass species and herbs was noted especially by the renewed grassland. Also sown grass species in the renewed grassland declined quickly and a considerable succession of native species occurred. These changes together with the effectiveness especially of soil and climatic factors were shown by a reduction of the primary production. Compared with the permanent grassland a small yield stability was shown by the renewed grassland. The slot seeding into a 5 cm broad rotary cut path was little effective and already in the second year the vegetation didn’t differ considerably from the permanent one concerning the yield and botanical composition.

The Productivity and Botanical Composition of Permanent, Temporary and Slot Seeded Grassland
The development of botanical composition and primary production was followed from 1993 to 1995 at the southern side of the Jizera Mountains on three-cutting permanent, temporary and slot seeded grassland.
