TI  - Competition-Productivity Relationship Between Some Common Grasses and Forbs  Plant Species in High Altitude Rangelands
AB  - 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.
