Publication The effects of different irrigation levels and nitrogen doses on growth, quality and physiological parameters of warm-season turfgrasses(Galenos, 2023-01-01) Yonter, Fikret; Zere Taskin, Sinem; Kesici, Muge; Candogan, Burak Nazmi; Cansev, Asuman; Bilgili, Ugur; Candogan, Burak Nazmi; CANDOĞAN, BURAK NAZMİ; Cansev, Asuman; CANSEV, ASUMAN; Bilgili, Ugur; BİLGİLİ, UĞUR; Yonter, Fikret; YÖNTER, FİKRET; ; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Tarla Bitkileri Bölümü.; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Biyosistem Mühendisliği Anabilim Dalı.; 0000-0002-2243-2993; GRO-3789-2022; AAH-4255-2019; AAH-1539-2021; AAH-3102-2021This research was conducted to determine to effects of different irrigation levels and nitrogen doses (ND) on the various warm-season turfgrasses at the Agricultural Training and Research Centre of the Bursa Uludag University Faculty of Agriculture for two years in a row. The experimental design was the randomized blocks in a split-split plot design with three replications. The main plot was irrigation levels (I1=25%, I2=50%, I3=75%, and I4=100% of pan evaporation), subplots were turfgrass species [hybrid Bermudagrass (Cynodon transvaalensis x Cynodon dactylon) cv. Tifdwarf, seashore paspalum (Paspalum vaginatum Sw.) cv. Seaspray, zoysiagrass (Zoysia japonica Steud.) cv. Zenit], and sub subplots were ND's (monthly 0.0, 1.25, 2.5, and 5.0 g N m-2). Visual turfgrass color and quality, clipping yield, leaf relative water content (RWC), loss of turgidity (LT), chlorophyll content (CC), and electrolyte leakage were measured. According to the results, significant differences were determined among irrigation levels, turfgrass species, and ND's for color, quality, clipping yield and physiological parameters. Turfgrass visual color, quality and clipping yield were shown to decrease significantly with decreases in irrigation water and N fertilizer. The study findings demonstrated that under a non-limiting water supply, irrigation could be decreased by adjusting N fertilizer rates with I3N3 treatments can maintain acceptable turfgrass visual color and quality under Mediterranean climatic conditions. In addition, at 25% (I1) deficit irrigation level, leaf RWC, CC decreased significantly, while an increase was determined in LT. This research indicated that under 75% (I3) deficit irrigation and N3 ND, acceptable quality can be maintained with 'seaspray' seashore paspalum under Mediterranean climate performed.Publication Irrigation level and nitrogen rate affect evapotranspiration and quality of Perennial Ryegrass (Lolium perenne)(Friends Science, 2015-01-01) Candoğan, Burak Nazmi; Bilgili, Uğur; Yazgan, Senih; Açıkgöz, Esvet; CANDOĞAN, BURAK NAZMİ; BİLGİLİ, UĞUR; Yazgan, Senih; Açıkgöz, Esvet; Uludağ Üniversitesi/Ziraat Fakültesi/Biyosistem Mühendisliği Bölümü.; Uludağ Üniversitesi/Ziraat Fakültesi/Tarla Bitkileri Bölümü.; AAH-3102-2021; AAH-1539-2021; GII-3222-2022; CBK-0678-2022This study examined the effects of different irrigation levels and nitrogen rates on perennial ryegrass (Lolium perenne L.) evapotranspiration and quality in a sub-humid climate over a two-year period (2007-2008). Nitrogen treatment (25 kg N ha(-1); N-1 and 50 kg N ha(-1); N-2) varied among main plots and irrigation levels (25%; I-1, 50%; I-2, 75%; I-3, 100%; I-4 and 125%; I-5 of the Class A pan evaporation) by subplot. Irrigation was performed at 3-day intervals during May-September using a pop-up sprinkler irrigation system, and N applied as a monthly rate during the irrigation period. Seasonal turfgrass evapotranspiration was found to vary by treatment from 309-1178 mm in 2007 and from 379-1097 mm in 2008. Turfgrass visual color, quality and clipping yield were shown to decrease significantly with decreases in irrigation water and N fertilizer. The study findings demonstrated that under a non-limiting water supply, irrigation could be decreased by adjusting N fertilizer rates according to turfgrass visual color and quality and that N1I4 or N2I3 treatments can maintain acceptable turfgrass visual color and quality under sub-humid climatic conditions.Publication Effects of different nitrogen sources on turf quality and plants growth of some warm-season turfgrasses(Soc Field Crop Sci, 2022-01-01) Zere, Sinem; Bilgili, Uğur; Zere, Sinem; BİLGİLİ, UĞUR; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Tarla Bitkileri Bölümü; 0000-0002-2243-2993; GRO-3789-2022; AAH-1539-2021This research was conducted to determine the effects of different nitrogen sources and rates on some warm-season turfgrasses under Mediterranean-type climate conditions in 2017-2018. The experiment was arranged in a randomized complete block design with split-split plot arrangement and having three replications. In the arrangement, turfgrass species as the main plot, nitrogen sources as the subplots, and nitrogen doses as the sub subplots. The main plots consist of four nitrogen sources: two slow-release fertilizers, one organomineral fertilizer, and one sewage sludge. Subplots consist of three warm-season turfgrass species; zoysiagrass (Zoysia japonica Steud.), hybrid Bermudagrass (Cynodon transvaalensis x Cynodon dactylon), seashore paspalum (Paspalum vaginatum Sw.), and one cool-season turfgrass species, tall fescue (Festuca arundinacea Schreb.). The nitrogen doses were as follows; 0.0, 2.0, 3.0 and 4.0 g m(-2). Turf color and quality were evaluated visually monthly. Also, clipping weight is determined. According to the result, slow-release and organomineral fertilizers can be considerable as N sources that will meet the nutritional needs of the turfgrasses. Zoysiagrass and seashore paspalum showed almost equivalent scores and gave sufficiently dark turf color and quality. Turfgrass should be fertilized at least with 3.0 g m(-2) N to provide acceptable turf color and quality.
