Öğe The effects of different harvest times on yield and some quality components of annual ryegrass (Lolium multiflorum lam.) varieties(Parlar Scientific Publications, 2021) Topcu G.D.; Celen A.E.; Ozkan S.S.This study was conducted in Bornova experimental fields of Department of Field Crops, Faculty of Agriculture, Ege University during 2015 and 2016 in order to determine the effect of harvest times on yield and some quality components of annual ryegrass (Lolium multiflorum Lam.) cultivars. The trial was conducted in randomized complete block design with three replications. Fresh herbage yield, dry matter content, crude protein content, crude ash content, crude cellulose content, metabolic energy and the contents of NDF and ADF were determined. Results indicated that the all characteristics were affected from cultivars and harvest times and that Rambo or Vespolini cultivars may be preferred. Harvest at heading stage gave more quality feed. © 2021 Parlar Scientific Publications.

Some commercial and widely used warm season turfgrasses (Cynodon dactylon cv. SR9554, Cynodon dactylon x Cynodon transvaalensis cv. Tifway-419) in addition to newly introduced turfgrasses (Paspalum vaginatum cv. Sea Spray and Zoysia japonica cv. Zenith) were chosen as plant material. To search the effect of overseeding techniques imposed in four different times (September 15, September 30, October 15 and October 30) on these selected warm season turfgrasses during fall season were aimed. For this purpose, dormancy period (day), germination speed (day), cover speed (day), fall transition (1-9 score) and spring transition (1-9 score) were tested in quality characteristics. Results of the study displayed that Lolium perenne L. can be practiced successfully in the ecologies like our trial location in Mediterranean ecology, in order to eliminate the problems of warm season turfgrasses in the dormancy process observed in winter season. Additionally, it was concluded that optimum overseeding time should be October 15. © by PSPÖğe Turf and playing quality traits of some new turfgrass alternatives in a mediterranean environment(Society of Field Crops Science, 2019) Kir B.; Avcioglu R.; Salman A.; Ozkan S.S.In an attempt to investigate the turfgrass and playing quality characteristics of some newly introduced warm season turf grasses and traditional cool season sports turf mixture, classical and contemporary techniques were imposed on the turfgrass experimental plots of the research area of Department of Field Crops, Agriculture Faculty of Ege University, Bornova/Izmir/Turkey. Some warm season turfgrasses (Cynodon dactylon cv. SR9554, Cynodon dactylon x Cynodon transvaalensis cv. Tifway-419, Paspalum vaginatum cv. Sea Spray and Zoysia japonica cv. Zenith) and traditional cool season sports turf mixture were tested in terms of visual turf quality and playing quality traits (ball rebound, ball roll and shock absorption) on a monthly and seasonal bases for three years under Mediterranean environmental conditions. Significant variations were determined among the turfgrass alternatives in all traits except years. It was concluded that Tifway-419 and Sea Spray turf grasses were the most successful and promising alternatives compared to the other options under Mediterranean environmental conditions. © 2019, Society of Field Crops Science.
