Özet
104 (9) It was suggested that these sort of investigations must be maintained with higher number of species and varieties using higher rates of nitrogen fertilizer. (10) According to the results of the experiment, Cynodon dactylon and Cynodon transvaaiensis or Agrostis stolonifera being in green color during every season, should be preferred in turfs to be established in our region.102 (1) Cynodon dactylon and Cynodon transvaalensis were the best grasses in terms of uniformity and Agrostis stolonifera followed them. The grasses in mixtures were not good in terms of this character because of the differences in leaf widths. Cynodon transvaalensis had a fine texture, Cynodon dactylon medium and the oilier grasses course. (2) Cynodon dactylon and Cynodon transvaalensis ranked first with regard to smoothness indicating the equal growth rates of individual crops in stands and the nitrogen dozes of 8 kg/da gave the best results. However, cool season grasses (mixture) had the most attractive colour-tone with the additive effect of 8 kg/da and 12 kg/da nitrogen dozes. Cynodon dactylon and Cynodon transvaalensis couldn't have such attractive colours because of the negative effect of the dead leaf sheets and stems remaining on the crops for long period of times. (3) The plant cover values determined by different vegetation techniques indicated the superiority of Agrostis stolonifera and Cynodon dactylon, Cynodon transvaalensis. It was concluded that the stoloniferous and rhizmatous growth habit of Cynodon dactylon and stoloniferous growth habit of Cynodon transvaalensis and Agrostis stolonifera played an important role in this phenomena. The components of mixture, Lolium perenne, Poa pratensis, Festuca rubra and Agrostis tenuis couldn't cover the area successfully because of the bunch type growth habit of these grasses. Consequently, some unsatisfactory cover values were determined on mixture stands. (4) There were an intensive weed infestation on the mixture plots composed of cool season grasses, whereas limited weed population on the Cynodon dactylon and Cynodon transvaalensis plots composed of warm season grasses covering the soil completely and highly adapting the Mediterranean climatic conditions. Agrostis stolonifera with its stoloniferous growth habit performed well although it was a cool season grass. This results confirmed the relationship between the growth habit of turfgrasses and weed infestations rates.
