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.

Tan›s›ndaki zorluklar, oldu¤undan daha az saptanmas›na neden olabilmektedir. ‹lginç bir flekilde ço¤u vaka Türkiye'den bildirilmifltir. Biz bu olgu sunumunda, atipik gö¤üs a¤r›s› ile baflvuran bir hastada saptad›¤›m›z çift sa¤ koroner arteri sunmaya amaçlad›k.

ABSTRACT A Rare Coronary Artery Anomaly; Double Right Coronary ArteryA double right coronary artery is an extremely rare coronary artery anomaly. Difficulties in diagnosis might cause underestimation of the incidence of double right coronary artery. Interestingly, most of the cases about this anomaly were reported from Turkey. In this case report, we aimed to present double right coronary artery in a patient who was admitted with atypic chest pain.

ÖZET u çalışma, Ege Üniversitesi Ziraat Fakültesi Tarla Bitkileri Bölümü'nün Bornova'da bulunun deneme tarlalarında, 2012-2014 yılları arasında 2 yıl süreyle sürdürülmüştür. Araştırmada, farklı biçim zamanlarında [I. Erken ilkbahar (Mart ayının son haftası), II. İlkbahar ortası (Nisan ayının ikinci haftası) ve III. Geç ilkbahar (Nisan ayının son haftası)] hasatları yapılan İtalyan çimi + baklagil yembitkisi karışımlarının (Vicia sativa, Lathyrus sativus, Pisum arvense) farklı karışım oranlarındaki (sırasıyla İtalyan çimi + baklagil olmak üzere; %100+0, %80+20, %60+40, %40+60, %20+80 ve %0+100) hasıl verimi ve verimle ilgili bazı özellikleri incelenmiştir. İki yıllık ortalama sonuçlara göre, Akdeniz iklim koşullarında kışlık ikinci ürün olarak değerlendirilen İtalyan çimi + baklagil karışımlarından sağlanan en yüksek verim değerlerinin, geç ilkbahar dönemindeki hasatlardan elde edildiği saptanmıştır. Ayrıca, yalın olarak yetiştirilen adi fiğin de en yüksek yeşil ot, kuru madde ve ham protein verimini (sırasıyla; 5378 kg/da, 1148 kg/da ve 230 kg/da) sağladığı sonucuna varılmıştır. Hasat zamanının ilerlemesiyle hasattaki baklagil oranı, NDF ve ADF oranları da artış göstermiştir. ABSTRACT his study was conducted in order to determine the effects of different harvest dates (Early Spring; the last week of March, Mid Spring; second week of April and Late Spring; last week of April) and various mixture rates (mixture of italian ryegrass + legume; 100+0%, 80+20%, 60+40%, 40+60%, 20+80% and 0+100%, respectively) of some annual legumes (Vicia sativa, Lathyrus sativus and Pisum arvense) with Italian ryegrass on the herbage yield and other yield characteristics. The field trials were carried out at Bornova Experimental Station, Ege University Faculty of Agriculture during the years of 2012-2014. As the average of 2-year results, it was determined that the highest yields were obtained from İtalian ryegrass + legume mixtures sown as winter second crop and harvested in late spring under Mediterrenean climatic conditions. However, the data also indicated that pure common vetch sowing provided the highest green matter, dry matter and crude protein yields, being 5378 kg/da, 1148 kg/da and 230 kg/da, respectively. Legume ratio, NDF and ADF rates increased by advancing harvest dates.

The sustainability of warm-season turfgrass species in winter dormancy is a major concern in Mediterranean ecology. The concept of overseed a lawn has been still new for many developing countries such as Turkey as part of a regular maintenance. Therefore, a 2-year study was conducted at the experimental fields of Ege University, Izmir/Turkey during 2014-2016 years to compare the effects of four different overseeding times (September 15, September 30, October 15 and October 30) on four warm season turfgrass species (Cynodon dactylon cv. SR9554, Cynodon dactylon × Cynodon transvaalensis cv. Tifway-419, Paspalum vaginatum cv. Sea Spray and Zoysia japonica cv. Zenith) by measuring visual turf quality (1-9 score) and some related characteristics as texture (mm), cover (1-9 score), weed infestation (1-9 score) and colour (1-9 score). ‘50% cv. Troya+50% cv. Esquire’ perennial ryegrass (Lolium perenne L.) mixture was used for overseeding in trial. According to results, visual turf quality performance of 6.0 scores and above were obtained from all treatments. We concluded that October 15 should be most suitable time for overseeding applications. Additionally, L. perenne L. can be practiced successfully in Mediterranean region in order to eliminate the concerns of warm-season turfgrasses in the winter dormancy period observed in cold temperatures. Highlights - No gaps were formed in plots and high coverage degrees were maintained during overseeding periods in all treatments. - Homogeneous spring transition was occurred from Lolium perenne L. to warm-season turfgrass species in all overseeding times. - Visual turf quality performance of 6.0 scores and above which is acceptable level were obtained from all overseeding times. - Better results were obtained from overseeding applications on Paspalum vaginatum and Cynodon dactylon × Cynodon transvaalensis. - The different results among the warm-season turfgrass species can provide effective information for future research studies.
