ABSTRACT
In Romania, secondary grasslands are an important resource for agriculture, respectively for animal breeding, because represents the cheapest source of forage. They require minimal management works for the preservation of their sward. The paper assesses the influence of organic fertilisation (sheep manure) on the vegetation sward of Trisetum flavescens (L.) P. Beauv. grassland by comparing two harvesting periods, respectively mid of June (cutting) and mid of September (sheep grazing). The vegetation surveys were realised with linear point quadrate method. There have been analysed several features of the vegetations, respectively species richness (S), Shannon biodiversity index (H`), number of grasses species, number of legumes species, number of species from other botanical families, specific contribution of main grass species (Trisetum flavescens) and legume species (Trifolium repens) and pastoral value. The experience has four variants of fertilisation, respectively non-fertilised, 20 t/ha manure, 40 t/ha manure and 60 t/ha manure. The correlation coefficients show the greatest influence of fertilisation on the specific contribution o the main legumes species Trifolium repens.

Keywords: grassland, manure fertilisation, Trisetum flavescens (L.) P. Beauv., vegetation.
