Performance of three turfgrass mixtures in the pedoclimatic conditions of NE Romania

摘要

Turf is composed of perennial grass species and cultivars mixed in different proportions to create various types of turf that meet certain requirements of utilisation or adaptation to climatic conditions such as excessive drought or strong shading. Inour study we analysed three different turf mixtures under the influence of differentiated fertilization and the climatic conditions in the NE region of Romania. The first mixture (Al) was composed of Festuca arundinacea 80% + Lolium perenne 10% + Poa pratensis 10%. The second mixture (A2) consisted of three cultivars of Lolium perenne mixed in equal proportions. The third mixture (A3) was composed of Festuca rubra 60% + Lolium perenne 20% + Festuca ovina duriusculla 10% + Poa pratensis 10%. Three typesof fertilizers were applied: ammonium nitrate, a complex fertilizer with nitrogen and phosphorus, and a commercial lawn fertilizer with macro and micronutrients. The experimental design was a split plot design with three replicates. Mixtures reacted positively to all three types of fertilizers. The best quality was observed for the A2 mixture, consisting of three cultivars of Lolium perenne.
