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.Publication Forage and grain yield performances of soybean lines(Univ Zagreb, Fac Agriculture, 2005-01-01) Bilgili, Uğur; BİLGİLİ, UĞUR; Şincik, Mehmet; SİNCİK, MEHMET; Göksoy, Abdurrahim Tanju; GÖKSOY, ABDURRAHİM TANJU; Turan, Zeki Metin; Açıkgöz, Esvet; Bursa Uludağ Üniversitesi/Ziraat Fakültesi.; 0000-0002-0012-4412; AAG-9296-2021; AAH-1539-2021; AAH-1811-2021Field experiments were conducted to evaluate the yield and yield components of twelve soybean genotypes as a forage and a grain crop in Marmara Region of Turkey in 2003-2004 growing seasons. Forage and dry matter yield and yield components at one vegetative stage (V5) and two reproductive stages (R2, and R4) and seed yield was determined in all soybean genotypes. The experiments showed that the harvest stages had significant effects on forage and dry matter yield, and R4 reproductive stage had the highest forage and dry matter yield. Dry matter partitioning of soybean plant parts was greatly affected by harvest stages, while the genotypes had little effect on dry matter partitioning of soybean plant parts. There were statistically significant differences between soybean genotypes in seed yield, but the differences were small. The correlations between forage and dry matter yield and seed yield were not statistically significant.Publication Development of maize (Zea mays L.) genotypes by using in vivo doubled haploid technique(Tarla Ürünleri, 2023-01-01) Taşkın, Sinem Zere; Bilgili, Uğur; Taşkın, Sinem Zere; BİLGİLİ, UĞUR; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Tarla Bitkileri Bölümü; 0000-0002-2243-2993; AAH-1539-2021; GRO-3789-2022Doubled haploid technology has become an increasingly popular and important tool for developing new maize (Zea mays L.) lines breeding. Although conventional plant breeding contributes significantly to maize development, it is time-consuming and has disadvantages such as using more labor and financial resources. Conventional maize breeding requires repeated self-pollination for about six to ten generations to obtain homozygous inbred lines, also 100% homozygous lines cannot be obtained at the end of this period. Completely homozygous lines can be produced in only two-three generations by using doubled haploid technology. In vivo induction of the maternal haploid method was used for the production of doubled haploid lines. Thirty-two different donors pollinated with haploid inducer line Stock6. Haploid seeds were identified visually by using dominant anthocyanin color marker genes R1-nj. Haploid induction rates (HIR) and chromosome doubling rate (CDR) were determined. Four hundred and eighty eight putative haploid seeds were obtained. The average haploid induction rate was calculated as 2.0%, the average chromosome doubling rate was 52.3%. Results of this study 20 doubled haploid lines were developed.Publication Development of maize (Zea mays L.) genotypes with in vivo doubled haploid technique(Tarla Ürünleri, 2023-01-01) Taşkın, Sinem Zere; Bilgili, Uğur; Taşkın, Sinem Zere; BİLGİLİ, UĞUR; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Tarla Bitkileri Bölümü; IWK-3846-2023; HTT-7536-2023Doubled haploid technology has become an increasingly popular and important tool for developing new maize (Zea mays L.) lines breeding.

Four nitrogen sources (NS) [NS1: ammonium nitrate (26%), NS2: Bursa City's wastewater treatment plant's waste, NS3: biogas production plant reactor waste, and NS4: food processing and canning factory's sludge waste] were used in the research. Four different nitrogen doses (0.0, 2.0, 4.0, and 6.0 g m(-2)) were applied. The sewage sludges were analyzed before the start of the research. It was determined that the heavy metal concentrations were below the limit values, and the plant nutrient content was high. Turfgrass color and quality observations were taken in the study, and turfgrass clipping yield was determined. The 4.0 g m(-2) nitrogen dose provided acceptable turf color and quality values among the sewage sludges. NS4 showed the best turf performance among the sewage sludges. Despite increased turf color and quality values, sewage sludge produced a low clipping yield. Food processing and canning factories' sewage sludges can be alternatives to a nitrogen source.
