Abstract
Facilitation or competition occurs among plant species when one species
alter ameliorates the environment for another species or when one
species needs the same sources of another species. The objective of this
study was to determine to facilitative or competitive effect on Bromus
variegatus, Festuca ovina, Koeleria cristata of growing with isolated,
Medicago papillosa, Astragalus microcephalus, Thymus parviflorus,
and Hypericum scabrum, and arranged in completely randomized
design. Plant height, above-and belowground biomass, and above-and
belowground Relative Neighbour Effect (RNE) significantly affected
main, some first- and second-order interaction depending on the year,
grasses species, surrounding. Aboveground biomass increased in
grasses, which grow in interaction with legume species, and significant
differences were determined between the grass species and years. While
average belowground biomass was 26,66 g/plant, the belowground
biomass of the grass species grown in interaction with M. papillosa and
A. microcephalus was positively affected and it was 31,58 and 34,99
g/plant, respectively. A. microcephalus had a facilitative effect on above
ground RNE of the grass species and the other species had a competitive
effect. All plant species had a competitive effect on belowground RNE
