The scientific objective of this study was to answer the question of whether sink limitation is also true for high quality wheat varieties. We examined the incorporation of 15N and 13C during phenological phases into vegetative parts and grains of Elite wheat Triso (E) and Quality wheat Naxos (A) when the spike is halved. Three splits of fertilizer were applied at EC 11, EC 30, EC 59, whereby 10% at EC 30 and EC 59 was 15N, and plants were also labelled with 13CO2. The application of only the third split as 15N, combined with spike-halving, resulted in a significantly higher 15N-content (+11%) of 0.486 mg 15N/g DM, compared to the control (0.437 mg15N/g DM). Labelling whole plants with 13CO2 at EC 59 resulted in a significantly higher 13C-content—40%—(0.223 mg 13C/g DM) of the grains of the control for Triso at the fully-ripe stage (EC 89), compared to Naxos (0.160 mg 13C/g DM). This superiority was reduced to 34%, and was also demonstrated by spike-halving (0.226 mg 13C/g DM, 0.169 mg 13C/g DM). Remobilization of 15N for control and spike-halving treatments were 68.2% and 61.1%, respectively. This clearly demonstrates that the reduction of the sink size by spike-halving leads to a 7% reduction in the remobilization of 15N from vegetative to reproductive tissues.

Determination of yield components, grain yield and some quality characteristics of different bread wheat varieties in Muğla Dalaman ecological conditions. Kayra, Ziyabey-98, Cumhuriyet-75, Kılınç, Adana-99, Ceyhan-99, Kaynarca and Toros-1003 bread wheat cultivars were used as plant material in this study, which was carried out with 3 replications according to the randomized block design in 2022 winter production season. Nitrogen fertilization was applied in total of 160 kg of pure nitrogen per hectare. In the study, significant differences were determined between bread wheat varieties in terms of the characteristics except starch ratio. The average plant height of the cultivars was between 88.2 - 118.4 cm, the average number of ears per square meter was between 414 - 606, the average number of grains per ear was between 35.6 - 45.2, the average of 1000 grain weight was between 41.8 - 53.2 g, the average grain yield was between 6160 - 8650 kg/ha, average hectoliter weight was between 75.8 - 81.2 kg/hl, average protein ratio was between 13.87 - 16.8%, average starch ratio was between 65.7 - 71.5%, average crude ash ratio was between 1.59 - 1.72% and the average crude fiber ratio was between 4.53 - 5.78%. Among the varieties, the Kaynarca variety attracted attention with its high yield and having the highest values in all other quality criteria, except for the raw ash ratio. Summarised Kaynarca variety can be successfully grown in our region as both an efficient yield and high quality variety. [ABSTRACT FROM AUTHOR]

Su ve azot eksikliği buğday ve diğer tahıllar gibi bitkilerin ürün verimliliğini etkileyen ana faktörlerden birisidir. İklim koşullarındaki artan değişiklikler nedeniyle buğday bitkisinin verim potansiyelinin açığa çıkması engellenmektedir. Son yıllarda kullanımı artan azot izotop tekniği sayesinde olumsuz çevre koşulları altında azot taşınımı ve azot kullanım verimliliği hakkında önemli bilgiler sağlanmaktadır. Bu çalışmada ekmeklik buğdayda 15N izotopu kullanılarak farklı gelişme dönemlerinde uygulanan kuraklık koşullarının azot taşınımı, verim ve kalite özellikleri ile stoma iletkenliği üzerindeki etkilerinin belirlenmesi amaçlanmıştır. Farklı gelişme dönemlerinde (sulu ve kuru koşul, erken kuraklık (çiçeklenme-hasat) ve geç kuraklık (tane dolum dönemi-hasat)) yağmur korunağı kullanılarak uygulanan yapay kuraklık koşulları ile çevresel varyasyon elde edilmiştir. Çalışmada; başakta tane sayısı, bin tane ağırlığı, tek başak verimi, metrekarede başak sayısı, bitki boyu, tane verimi, biyomas verimi, stoma iletkenliği, tane protein ve kül oranı, sap δ15N (‰), bayrak yaprak δ15N (‰) ve tane δ15N (‰) içerikleri değerlendirilmiştir. Elde edilen sonuçlara göre; verim ve verim öğeleri generatif dönem boyunca uygulanan kuraklık uygulamalarından olumsuz yönde etkilenmiştir ve bu nedenle ekmeklik buğday üretiminde generatif dönem kuraklık stresine neden olabilecek uygulamalardan kaçınılması gerektiği sonucuna ulaşılmıştır. Ayrıca azot kullanım etkinliğinin bitki su kullanımının kısıtlanması ile azaldığı ve kuraklık dönemi boyunca su kullanım etkinliğinin azaldığı anlaşılmıştır. Tüm bunlara ek olarak kuraklık dönemi boyunca bitki metabolik aktivitelerinin azalması sonucu azot tüketiminin kısıtlanmasına bağlı olarak azotun verim potansiyeline katkısının azaldığı sonucuna ulaşılmıştır. Sulu koşulda tane δ15N içeriğinin sulama ile kuru koşula göre 13420 ‰ değerinden 9278 ‰ değerine azaldığı sonucuna ulaşılmıştır. Ayrıca sapa kalkma döneminde uygulanan azotun tane δ15N değerinin (15269 ‰) kardeşlenme döneminde uygulanan δ15N içeriğine (8975 ‰) oranla daha yüksek azot içeriğine ulaşılmasını sağlamıştır. Azotun metabolik faaliyetlere etkin bir şekilde katılması için kardeşlenme ve sapa kalkma dönemlerinde azotlu gübrelemenin uygun zamanda uygulanması ve özellikle sapa kalkma döneminde uygulanan azotun generatif dönem boyunca buğday bitkisinin farklı kısımlarında daha etkin azot taşınımına ve azot kullanımına neden olduğu sonucuna ulaşılmıştır., Water and nitrogen shortage are one of the main limiting factors of crop productivity such as wheat and cereals. Increased variation and changes in climate conditions are expected to dominate yield potential of wheat. Nitrogen isotope technique widely used in recent years provides useful information about mobilization and nitrogen use efficiency under environmental constraints. This study aimed to determine the effects of drought conditions applied during different growing periods on nitrogen uptake by using stable 15N isotope, yield and quality properties and stomatal conductivity of bread wheat. Environmental variation was obtained by designing 4 artificial practices (irrigated condition, rainfed condition, early drought (flowering-harvest) and late drought (grain filling-harvest) by rainout shelter with covering progress about drought in different growing periods. Number of grains per spike, 1000 grain weight, single spike yield, spike numbers per square meter, plant height, grain yield, biomass yield, stomatal conductance, protein, ash content and stem δ15N (‰), flag leaf δ15N (‰), grain δ15N (‰) values were determined. The drought period from the beginning of flowering till harvest of plants had adverse impact on grain yield and yield components. The results clearly indicated the practices that may cause drought stress in the generative period should be avoided. In addition, nitrogen use efficiency of bread wheat was disrupted with the decrease in the amount and efficiency of plant water use during drought periods. The results also revealed that contribution of nitrogen to crop yield decreased due to less consumption of nitrogen in plant metabolic activities during drought periods. Based on the results additional water supply decreased δ15N content in mature grains from 13420 ‰ to 9278 ‰. Nitrogen applied in stem elongation period had greater contribution to grain δ15N content (15269 ‰) compared to tillering growth stage (8975 ‰). Nitrogenous fertilizer application time suggested not to be delayed to improve nitrogen contribution in metabolic activities and to prevent postponing the tillering and stem elongation periods. The application of nitrogen improved mobilization and efficiency of nitrogen contribution to different plant parts during generative development stages of bread wheat.

Bu çalışma ile Aydın ekolojik koşullarında bazı mısır çeşitlerinin farklı sulama düzeylerinde tane verimi, verim öğeleri ve kalite özelliklerine ait performansların belirlenmesi amacıyla 2021 yılında yürütülmüştür. Deneme materyali olarak 5 adet hibrit mısır çeşidi kullanılmıştır (M14G44, P2085, DKC6980, TORRO ve SYFUERZA çeşitleri). Denemede çeşitlere tam sulama ve kısıtlı sulama dozları (sırasıyla tarla kapasitesinin %100’ü ve %60’ı) uygulanmıştır. İncelenen özelliklere bakıldığında koçan uç boşluğu 34.34 mm - 14.04 mm, koçanda tane sayısı 711 adet - 389 adet, koçan çapı 54.33 mm - 42.58 mm, bin tane ağırlığı 367.6 g - 249.6 g, tane verimi 1857 kg da-1 - 757.3 kg da-1, tanede ham kül oranı %2.148 - %1.266, tanede ham yağ oranı %4.183 - %2.13, tanede ham lif oranı %2.450 - %1.945, tanede ham protein oranı %7.93 - %11.62, tanede ham nişasta oranı %64.63 - %57.42 arasında değiştiği belirlenmiştir. Elde edilen sonuçlara göre tam su dozunun verim ve verim öğelerinde önemli etkilerinin olduğu belirlenmiştir. Öncelikle çeşitlerin mevcut ekolojik koşullarda (%100 su) yüksek verim potansiyeline sahip oldukları bulunmuştur. Buna ek olarak, ekonomik üretim için sulama düzeyinin tarla kapasitesinin %60’nın üzerinde olması gerektiği bulunmuştur. Tek yıllık veriler ışığında tane verimi bakımından SYFUERZA çeşidinin kısıntılı sulamayı tolere etme konusunda ümitvari, P2085 çeşidinin ise kısıntılı sulamaya karşı daha hassas olduğu söylenebilir., The study was aimed to determine yield and quality components of corn hybrids under water deficiency in Aydın ecological condition in 2021. Five corn hybrids (M14G44, P2085, DKC6980, TORRO and SYFUERZA) were grown under full and deficit irrigation (100% and 60% field capacity respectively) levels. According to findings obtained unfilled cob height ranged between 14.0 mm and 34.3 mm, number of seeds per ear ranged between 389 and 711, ear diameter changed from 42.6 to 54.3 mm, thousand seed weight ranged between 249.6 and 367.6 g, grain yield ranged between 7573 and 18570 kg ha-1. In terms of quality characteristics, crude ash ratio was observed between 1.27% and 2.15%, crude oil ratio was between 2.13% and 4.18%, crude fiber ratio was between 1.95% and 2.45%, crude protein ratio was between 7.93% and 11.62% and crude starch ratio was between 57.42% and 64.63%. The results showed that full irrigation level has statistically significant effect on yield and yield components with increasing levels. It was found that all cultivars have generally high yield potential under the current ecological conditions (100% water). In addition, the irrigation level should be above 60% of the field capacity for economic production. Considering one year results and in terms of grain yield, it can be said that SYFUERZA variety is promising in tolerating limited irrigation, while P2085 variety is more sensitive.

In a split N-application system, the objective was to quantify N/
15 N in gluten and non-gluten proteins after the late application of 30 or 60 kg N, whereby 10% of the third split was applied as15 N. This fertilization was combined with a reduced water supply for 21 days (well-watered (ww); water deficit (wd)). German spring wheat cultivars, Elite wheat Taifun, Quality wheat Monsun and cultivars from the Mediterranean territory, Golia, Gönen, were examined. The protein content in gluten was for 30 kg N, ww, similar for Taifun, Golia, and Gönen, but markedly lower in Monsun (231, 245, 247, 194 mg protein/g DM). The water deficit increased the protein content in the gluten of Golia and Gönen and was higher than that of Taifun and Monsun (297, 257, 249, 202 mg protein/g DM). Fertilization of 60 kg N, ww, did not result in any change in the protein content in gluten and differences between the cultivars were not detectable. The15 N protein in gluten was for 30 kg N, ww, markedly higher in Gönen (2.32 mg15 N protein/g DM), compared to Golia and Monsun (1.93, 1.50 mg15 N protein/g DM), and similar in Taifun (1.64 mg15 N protein/g DM).15 N fertilizer uptake into gluten was stimulated by water deficit for 30 and 60 kg N, leading to significantly increased15 N protein in Golia and Gönen, (2.38, 2.99, 4.34, 5.87 mg15 N protein/g DM). Fertilization of 60 kg N led to a proportional two-time increase in the15 N gluten protein of the four cultivars, in ww and wd plants. Assessed on the basis of15 N fertilizer allocation under wd conditions into gluten proteins, Golia and Gönen have a stronger sink activity, compared to Taifun and Monsun.

Thisstudy was conducted on the research and experimental fields at Adnan MenderesUniversity Agriculture Faculty Research Farm during wheat growing period in2016/2017. The experiment included the effects of three different mineralnitrogen fertilizer doses (0, 9, 18 kg/da) and five different solid biogaswaste doses (0, 2, 4, 6, 8 t/da) and their combinations on the total phenolcontent and antioxidant activity of wheat. Totalphenol content was determined by using gallic acid standard according toFolin-Ciocalteu method of grains of Ceyhan-99 variety. Determination of totalantioxidant activity was performed using 2,2 diphenyl 1 picryl hydrazyl (DPPH)free radical. It is desirable that total phenolic content in bread wheat grainis high in order to prevent the damage of free radicals. When the resultsobtained in the study were examined, solid biogas waste application and mineralnitrogen application and their combinations caused total phenol content inbread wheat plant to change between 158.15-361.84 µg GAE/g. The highestphenolic content was obtained from the application of 18 kg N/da and 2 t/dasolid biogas waste with 331.99 µg GAE/g, while the lowest total phenolicsubstance content was obtained from 215.83 µg 0 kg N/da and 2 t/da solid biogaswaste application. Antioxidant activity varied between 16.17-29.68% and thehighest antioxidant activity was obtained from 18 kg N/da and 2 t/da solidbiogas waste application, while the lowest antioxidant activity was 9 kg N/daand 8 t/da also obtained in solid biogas waste application. In general, betterresults were obtained in combination with 2 t/da solid biogas waste and 18 kg/damineral nitrogen dose., Bu çalışma AdnanMenderes Üniversitesi Ziraat Fakültesi Araştırma Ve Uygulama Çiftliğinde2016/2017 buğday üretim sezonunda tesadüf blokları bölünmüş parseller denemedesenine göre yürütülmüştür. Çalışmanın amacı üç farklı mineral azot gübre dozu( 0, 9, 18 kg/da ) ve beş farklı katı biyogaz atık dozu uygulamasının (0, 2, 4,6, 8 ton/da) ve bunların kombinasyonlarının buğday bitkisinde ki toplam fenoliçeriği ve antioksidan aktivitesini araştırmaktır. Toplam fenol miktar tayiniCeyhan-99 çeşidine ait tanelerin Folin- Ciocolteu yöntemine göre galllik asitstandardı kullanılarak gerçekleştirilmiştir. Toplam antioksidan aktivite tayini2,2 diphenüly1 picrylhy dorozyl (DPPH) serbest radikali kullanılarak gerçekleştirilmiştir.Ekmeklik buğday tanesinde toplamfenolik madde içeriği serbest radikallerin zararını önlemek amacı ile yüksekolması istenir. Yapılançalışmada elde edilen sonuçlar incelendiğinde, katı biyogaz atık uygulaması vemineral azot uygulaması ile bunların kombinasyonları ekmeklik buğday bitkisindetoplam fenol içeriği 158.15-361.84 µgGAE/g arasında değişmesine neden olmuştur. En yüksek fenolik madde içeriği331.99 µg GAE/g ile 18 kg saf N/dauygulaması ve 2 ton/da katı biyogaz atık uygulamasından elde edilir iken endüşük toplam fenolik madde içeriği 215.83 µg GAE/g değeriyle azot kullanılmayanve 2 ton/da katı biyogaz atık uygulamasından elde edilmiştir. Antioksidanaktivite değerleri % 16.17-29.68 arasında değişiklik göstermiştir ve en yüksekantioksidan aktivitesi 18 kg saf N/da ve 2 ton/da katı biyogaz atıkuygulamasından elde edilir iken en düşük tanede antioksidan aktivitesi ise 9 kgsaf N/da ve 8 ton/da katı biyogaz atık uygulamasında elde edilmiştir. Denemedegenel olarak 2 ton/da katı biyogaz atığı ile 18 kg/da mineral azot dozukombinasyonunda daha iyi sonuçlar tespit edilmiştir.

Karabuğday bitkisi tane kalitesi ve kullanım özellikleri nedeniyle tahıl benzeri (pseudocereal) olaraknitelendirilen Asya kökenli bir bitkidir. Vejetasyon süresinin kısa olmasının getirdiği birçok avantaj ile birliktediğer tahıl türlerine oranla farklılık meydana getirmektedir. Ayrıca tanesinin en önemli özelliklerinden birisi degluten intoleransı rahatsızlığı bulunan bireylerin glutensiz özelliğinden dolayı tanesinden ve ürünlerindenrahatlıkla faydalanabilmesidir. Karabuğday bitkisinin ekonomik ve beslenme fizyolojisi açısından sahip olduğuözelliklerinden dolayı ekim alanlarının gelecekte artması beklenmektedir. Yapılan çalışmada Aydın ekolojikkoşullarında Güneş karabuğday çeşidinin 6 farklı ekim sıklığında (4, 6, 8, 10, 12 ve 14 kg/da) ekimi yapılarakkarabuğday bitkisinin yetiştirilme olanakları ve ekim sıklığının bitkinin verim ve verim öğeleri ile tane kaliteözellikleri üzerine etkileri incelenmiştir. Karabuğday bitkisi farklı ekim sıklıklarında tane verimi, bin taneağırlığı ve metrekarede bitki sayısı bakımından istatistiksel anlamda farklılık gösterirken, bitki boyu, proteinoranı, hektolitre ağırlığı ve yaprak alan miktarı bakımından farklılıklar bulunmamıştır. Çalışmadan elde edilenortalama sonuçlar özetlendiğinde tane verimi 244.2-297.7 kg/da, bin tane ağırlığı 25.6-30.7 g, bitki boyu 64.7-71.7 cm, metrekarede bitki sayısı 23.5-64.0 adet, yaprak alan miktarı 12.7-15.0 cm2, tanede protein oranı %11.75-12.56 ve hektolitre ağırlığının 60.1-61.0 kg/hl arasında değişim göstermiştir. Çalışma sonucunda tane verimi vekalitesi ile tohumluk kullanım miktarının dikkate alınarak Aydın ekolojik koşullarında 8 kg/da'lık tohumlukmiktarının yeterli olduğu sonucuna varılmıştır. Özellikle tane verimi bakımından dünya ortalamasının oldukçaüzerine çıkarak bölgemizde tane üretiminde önemli bir potansiyele sahip olduğu söylenebilir.

- Abstract
M ısır ülkemizde kullanım alanları geniş, üretimi ise yetersiz olan bir bitkidir. Bu sorun ancak ikinci ürün tarımıyla çözülebilir. Bu nedenle planlanan çalışma 2005, 2006 ve 2007 yıllarında Adnan Menderes Üniversitesi Ziraat Fakültesi Uygulama Çiftliğinde birinci ve ikinci ürün olarak yürütülmüştür. Deneme materyali 32K61 ve 31G98 çeşitleridir. Bitkilerin vejetatif ve generatif dönemlerdeki gün sayıları ile Büyüme Derece Gün (BDG) değerleri hesaplanmıştır. Ayrıca tane verimi, verim öğeleri ve tarımsal özellikler ve kalite özellikleri belirlenmiştir. Çalışma sonucunda mısırın birinci üründe ikinci üründen daha kısa sürede vejetasyon periyodunu tamamladığı saptanmıştır. Bu kısalmanın generatif dönemde olduğu gözlenmiştir. BDG değerleri ve iklim verileri doğrultusunda bitkinin büyüme ve gelişme dönemlerine sıcaklığın doğrudan etki ettiği sonucuna varılmıştır. Tane verimi, verim öğeleri, tarımsal ve kalite özelliklerinin tamamında birinci ürün ortalaması ikinci üründen yüksek çıkmıştır. Ürünler arasında tane verimi, koçanda tane sayısı ve tanede yağ oranı değerlerinde farklılık belirgin olmuştur

Bu çalışmanın amacı farklı dozlarda ve farklı uygulama zamanlarında uygulanan kükürt’ün mısırın gelişimine olan etkisinin belirlenmesidir. Buna ek olarak kükürt'ün mısır tanesinde mineral içeriğine olan etkisi de incelenmiştir. Bunun için 2013 ve 2014 yıllarında kurulan çalışma Adnan Menderes Üniversitesi Ziraat Fakültesi deneme tarlalarında yürütülmüştür. Çalışmada 7 melez mısır çeşidi (İnove, Calipso, Miami, İndaco, Locroso, 31G98 ve Lacasta) kullanılmıştır. Kükürt uygulama formu elementer toz kükürt şeklinde olmuştur. Uygulama miktarı ise baz doygunluğuna göre katyon değişim kapasitesi hesaplanarak pH'yı bir birim düşürebilmek için gereken miktar “doz 1” olarak tanımlanmış ve bunun iki katı “doz 2” olarak belirlenmiştir. Buna göre kükürt uygulama şekilleri; “standart” (hiç kükürt uygulanmamış standart gübreleme N,P,K yapılmış), “Uyg.1” (ekimde doz 1 uygulaması), “Uyg.2” (ekimde doz 2 uygulaması), “Uyg.3” (ekimden yaklaşık 2 ay önce doz 1 uygulaması) ve “Uyg.4” (ekimden yaklaşık 2 ay önce doz 2 uygulaması) olarak planlanmıştır. Tüm bunlara ek olarak hiç gübre verilmemiş “kontrol” parselleri de kurulmuştur. Deneme sonucunda bitkilerin vejetatif ve genaratif dönem için elde edilen büyüme derece gün (BDG) değerleri, tanede çinko (Zn), mangan (Mn), demir (Fe), bakır (Cu) miktarları incelenmiştir. Elementer kükürt mısırın vejetasyon süresini uzatmıştır. Özellikle generatif olum süresini uzatmış ve hesaplanan BDG değerlerini etkilemiştir. Çalışmanın sonucunda S dozlarının, uygulama zamanlarının ve interaksiyonunun tanede Zn, Mn, Fe, ve Cu oranları üzerine önemli etkileri saptanmıştır. En yüksek tanede Zn miktarı kontrol uygulamasında, Mn ve Fe miktarları Uyg2.'de ve Cu miktarı ise Uyg4.'de ölçülmüştür., The purpose of the study was investigated effect of different sulfur doses and application dates on corn plant growing.

This study was conducted to determine the suitable irrigation dose (0, 40, 80 and 120 mm) to compansate yield and bread-making quality of four common wheat varieties under the Mediterranean ecological conditions for two years. Grain yields of Pamukova, Sagittario, Fiorino and Golia ranged between 2864 kg ha-1 (Golia, 0 mm) and 6021 kg ha-1 (Sagittario, 80 mm). The supplemental irrigation caused the grain yield to increase significantly up to 58%. The highest grain yields could be ensured with a supplemental irrigation of 80 mm. The protein content, sedimentation value and gluten index among the bread making quality parameters have been found to be at the highest levels for all varieties in both trial years when no supplemental irrigation has been applied. Increases of gluten index were observed with supplemental irrigations. Optimum levels of quality characteristics were obtained with 80 mm supplemental irrigation which is also suited to the level of the highest grain yield. Thus it could be suggested that in order to combine acceptable quality characteristics with the highest grain yield in the region, a supplemental irrigation up to 80 mm could be applied.

Akdeniz iklim kuşağında üretilen arpanın büyük bir bölümü hayvan yemi olarak değerlendirilmektedir. Buna karşın arpa çeşitlerinde tanenin kapsamlı besin değerlerinin belirlendiği fazlaca çalışma bulunmamaktadır. Bu çalışma arpa tanesinin besin değerlerinin belirlenmesi amacıyla Aydın koşullarında 2013 ve 2014 yıllarında yürütülmüştür. Araştırmada materyal olarak Akhisar98, Vamıkhoca98, Hilal ve Sancak arpa çeşitleri kullanılmıştır. Tek başakta tane verimi (TBV), başakta tane sayısı (BTS), bin tane ağırlığı (BTA), tanede protein oranı, tanede nişasta oranı, tanede yağ oranı, tanede kül oranı ve tanede selüloz oranı değerleri ölçülmüştür. Tek başakta tane verimi 1.10 g – 3.68 g aralığında ve başakta tane sayısı değeri ise 20.17 – 71.60 aralığında ölçülmüştür. Bin tane ağırlığı değeri 39.12 g – 70.36 g aralığında hesaplanmıştır. Tanede protein oranı %10.31 – %12.05 aralığında, tanede nişasta oranı %42.00 – %53.38, tanede yağ oranı %1.58 - %1.85, tanede kül oranı %2.54 - %2.72 ve tanede selüloz oranı %6.68 – %9.06 aralığında olduğu ölçülmüştür. Çalışmanın ilk yılında tek başakta tane verimi, başakta tane sayısı ve bazı tane kalite parametreleri (Tanede protein oranı, tanede kül ve yağ oranı) ikinci yıldan düşük bulunmuştur. Hilal çeşidi en yüksek tek başakta tane verimi, bin tane ağırlığı ve tanede nişasta oranı değerleri ile öne çıkmıştır. Buna ek olarak çeşit düşük selüloz oranı ile yem kalitesini artırabileceğini göstermiştir. Although the large part of barley produced in Mediterranean conditions is considered as animal feed, a large number of studies about grain nutritional value haven't been done comprehensively so far. This study was carried out in Aydın location in Turkey in 2013 and 2014 in order to find out the nutritional values of the grain. In this research, Akhisar98, Vamıkhoca98, Hilal and Sancak barley cultivars were used as the material of this study. Grain yields per spike, numbers of grain per spike, 1000 grain weight, and protein rates of grain, starch rates of grain, oil rates of grain, ash rates of grain and cellulose rates of grain were measured. According to average result in two years' grain yield per spike and numbers of grain per spike were measured as the ranges between 1.10 g – 3.68 g and 20.17 – 71.60 respectively. 1000 grain weight between 39.12 g – 70.36 g. protein rates of grain, starch rates of grain, oil rates of grain, ash rates of grain and cellulose rates of grain were measured as the following ranges; %10.31 – %12.05, %42.00 – %53.38, %1.58 - %1.85, %2.54 - %2.72 and %6.68 – %9.06 respectively However, grain yield per spike, numbers of grain per spike and some quality parameters such as grain protein rates, grain ASH rates and grain oil rates were measured much lower in the first year than those measured in the second year in this study. Hilal barley cultivar came forward by giving the highest grain yield per spike, 1000 grain weight and starch rates of grain. In addition to, the cultivar gave the lowest cellulose rate of grain when measured in this experiment. As a result, it is suggested that the cultivar could be increased by feed quality.

Buğday talebimizi karşılamak ve dünyadaki buğday pazarında yerimizi alabilmek amacıyla üretimimizin yılda yaklaşık % 2 oranında arttırılması gerekmektedir. Üretimin artırılması ancak verim artışıyla mümkün olacaktır. Bunun için yapraktan besin elementlerinin uygulanması güncel bir yoldur. Buğdaya yapraktan uygulanan besin elementlerinin etkisi konulu çalışma Adnan Menderes Üniversitesi Ziraat Fakültesinde 2011 ve 2012 yıllarında yürütülmüştür. Materyal olarak 4 buğday çeşidi (Pamukova 97, Golia 99, Sagittario ve Negev) seçilmiştir. Çalışmanın amacı sapa kalkma döneminde yaprağa uygulanan Country (oksin ve % 8 Zn) , Cyto-Wachs (% 0.1 amino asit, % 0.02 Fe, % 0.1 Mn, % 0.002 Zn), K-Sparrow (% 5 P ve % 25 K) ve Boroline (% 10 B) gübrelerinin buğdayın verim ve kalite özelliklerine olan etkilerinin belirlenmesidir. Çalışmamızda yapraktan uygulamaların tane verimi üzerine olumlu etkisi olduğu görülmüştür. Ancak tane kalitesine yönelik etkiler çok belirgin olmamıştır. Genel olarak bin tane ağırlığında olumlu etkiler görülürken hektolitre ağırlığı değişmemiştir. Protein oranı bölge ortalamalarının üzerinde olmakla birlikte uygulamaların etkisi fazlaca görülmemiştir. Buna karşın yaprak gübre uygulamalarının nişasta oranı üzerine etkisi daha belirgin bulunmuştur. Çalışmanın sonucunda bölgemiz için Sagittario ve Golia çeşitleri ile Country ve Cyto-Wachs gübreleri önerilebilir., In order to meet our demand and our place in the world market for wheat, wheat production should be increased by 2 % per year. The increase in wheat production is only possible by increasing the yield. Therefore foliar application of nutrients is a current way of yield increase. The working theme of the influence of foliar application on wheat was processed in 2011 and 2012 at the Adnan Menderes University. For the material of the experiment 4 wheat varieties (Pamukova 97, Golia 99, Sagittario and Negev) were selected. The aim of the study was to quantify the effect of foliar application as Country (auxin and % 8 Zn), Cyto-Wachs (% 0.1 amino-acid, % 0.02 Fe, % 0.1 Mn, % 0.002 Zn), K-Sparrow (% 5 Pand % 25 K) and Boroline (% 10 B) at the time of shooting stage on yield and quality characteristics of wheat. Our results showed that the foliar applications have a positive effect on grain yield. However, it was no clear effects on the studied quality parameters are found. Foliar application resulted in positive effects in 1000-kernel weight, but no mainly changes in hectoliter-weight were observed. The protein content of wheat varieties were measured above the average for the region, but no clear effects of foliar application can be observed. Compared to the protein content, the effects of the starch content parameter was more pronounced. In summary, the varieties Sagittario and Golia and the fertilizers Country and Cyto-Wachs are recommended for our region.

This study examined the effects of a reduced wheat sowing rate (250 vs. 500 grains m–2) on grain yield, uptake of15N into grains, and the incorporation into gluten and non-gluten proteins of wheat under field conditions in the Aegean region. A single15N application was applied at stem elongation, at flowering, or at both developmental stages. Each15N treatment included either additional water supply, or no additional water supply at flowering. Sowing rate (either 250 or 500 grains m–2) had no impact on grain yield. Grain yield increased with additional water supply, but at the expense of protein quality, because of a decrease in the protein content of gluten. The15N content of the gluten and non-gluten proteins at grain maturity was not different among cultivars.15N applied at both stem elongation and flowering was found in comparable amounts in grains and protein fractions, irrespective of sowing rate.

20 ÖZET EÜZF Tarla Bitkileri Bölümünün deneme tarlalarında 1994-1995 yıllarında yürütülen çalışmamızda, tarla araştırmalarına 1994 yılı sonbaharında ve ekim ayında başlanmış, çıkış gözlemlen sonrasında ölçüm ve incelemeler yapılmıştır. Bu amaçla çimlenme oranı, kardeşlenme oranı, Botanik Kompozisyon oranı, vejetasyon fizyonomileri ile üstten tohumlanan buğdaygillerin yeşil ot verimleri gibi özellikler ele alınmıştır. Elde edilen sonuçlar aşağıdaki şekilde özetlenmiştir; (1) Akdeniz ikliminde ve Bornova ekolojik koşullarında Cynodon dactylon ve Cynodon transvaalensis parsellerin kış döneminde yeşillendirilmesi amacıyla Lolium perennne 'nin başarıyla kullanılması mümkündür, bu açıdan Lolium multiflorum da denenmelidir. (2) Üstten tohumlamada kullanılan Lolium perenne türü diğer türlerin özelliklerine de bağlı daha yüksek bir yeşil ot verimi (Biomas) oluşturmakta, bu durum botanik kompozisyon oranlarına da yansımaktadır. (3) Bu tür çalışmaların 2 veya 3 yıl tekrarlanmasıyla daha sağlıklı sonuçlara varılabilecektir. (4) Üstten tohumlamada kullanılan Lolium multiflorum 'un Fıdecikleri Lolium perenne' âen daha hızlı kardeşlenmekte, üstten tohumlanan buğdaygillerin toprakla temas ederek çimlenebilmeleri açısından Cynodon dactylon daha başarılı görülmektedir. (5) Vejetasyon fizyonomisi açısından Lolium perenne'nin Cynodon dactylon üzerine üstten tohumlanması nisbeten daha iyi sonuç vermektedir. (6) Akdeniz iklim koşullarında kışın sararan ancak yazın çok iyi performans gösteren sıcak iklim buğdaygillerinin bu olumsuz özelliklerini gidermek amacıyla uygulanan üstten tohumlama konusunda bölgemizde ilk defa yürüttüğümüz araştırmamızın yıl, gübre, sulama ve çeşit faktörlerini de ele alacak şekilde genişletilerek sürdürülmesi daha sağlıklı bilgiler elde etmeyi sağlayacaktır. 21 SUMMARY In this research conducted in the experimental fields of Field Crops department of Agriculture Faculty of Aegean University in 1994-1995. Investigations have been started in October of autumn of 1994 and tests and measurements were done after germination. The germination rates, tillering, botanical composition rates, vegetation physionomies and overseeded grass green matter yields were examined for this aim. The results taken from the experiment can be summarised as followings; (1) Lolium perenne could be successfully used to be provide a green colour on the Cynodon dactylon and Cynodon transvaalensis plots during winter period under the Mediterranean ecological conditions of Bornova. Lolium multiflorum should also be experimented in detail from this standpoint. (2) More dependable results could be achieved by 2 or 3 year replications of these studies. (3) The seedlings of Lolium multiflorum used in the overseeding were tillering more rapidly than Lolium perenne and Cynodon dactylon were more successful than Cynodon transvaalensis in terms of providing better conditions for soil contact and germination. (4) The overseeding of Lolium perenne on Cynodon dactylon gave respectively better result with regard of vegetation physionomy. (5) Our study; conducted for the first time in our region and using overseeding technique to compensate the unfavourable characteristics of warm season grasses showing very low performance in the summer period of Mediterranean climatic conditions but also yellow colour in winter, should be continued including year, fertiliser, irrigation and variety factors and more dependable information should be obtained. 18

- Abstract
Although the large part of barley produced in Mediterranean conditions is considered as animal feed, a large number of studies about grain nutritional value haven't been done comprehensively sofar. This study was carried out in Aydın location in Turkey in 2013 and 2014 in order tofind out the nutritional values of the grain. In this research, Akhisar98, Vamıkhoca98, Hilal and Sancak barley cultivars were used as the material of this study. Grain yields per spike, numbers of grain per spike, 1000 grain weight, and protein rates of grain, starch rates of grain, oil rates of grain, ash rates of grain and cellulose rates of grain were measured. According to average result in two years' grain yield per spike and numbers of grain per spike were measured as the ranges between 1.10 g - 3.68 g and 20.17 - 71.60 respectively. 1000 grain weight between 39.12 g - 70.36 g. protein rates of grain, starch rates of grain, oil rates of grain, ash rates of grain and cellulose rates of grain were measured as the following ranges; %10.31 - %12.05, %42.00 - %53.38, %1.58 - %1.85, %2.54 - %2.72 and %6.68 - %9.06 respectively However, grain yield per spike, numbers of grain per spike and some quality parameters such as grain protein rates, grain ASH rates and grain oil rates were measured much lower in the first year than those measured in the second year in this study. Hilal barley cultivar came forward by giving the highest grain yield per spike, 1000 grain weight and starch rates of grain. In addition to, the cultivar gave the lowest cellulose rate of grain when measured in this experiment. As a result, it is suggested that the cultivar could be increased by feed quality.

ABSTRACT In order to meet our demand and our place in the world market for wheat, wheat production should be increased by 2 % per year. The increase in wheat production is only possible by increasing the yield. Therefore foliar application of nutrients is a current way of yield increase. The working theme of the influence of foliar application on wheat was processed in 2011 and 2012 at the Adnan Menderes University. For the material of the experiment 4 wheat varieties (Pamukova 97, Golia 99, Sagittario and Negev) were selected. The aim of the study was to quantify the effect of foliar application as Country (auxin and % 8 Zn), Cyto-Wachs (% 0.1 amino-acid, % 0.02 Fe, % 0.1 Mn, % 0.002 Zn), K-Sparrow (% 5 P and % 25 K) and Boroline (% 10 B) at the time of shooting stage on yield and quality characteristics of wheat. Our results showed that the foliar applications have a positive effect on grain yield. However, it was no clear effects on the studied quality parameters are found. Foliar application resulted in positive effects in 1000-kernel weight, but no mainly changes in hectoliter-weight were observed. The protein content of wheat varieties were measured above the average for the region, but no clear effects of foliar application can be observed. Compared to the protein content, the effects of the starch content parameter was more pronounced. In summary, the varieties Sagittario and Golia and the fertilizers Country and Cyto-Wachs are recommended for our region. [ABSTRACT FROM AUTHOR]

This study was conducted at the experimental field of Adnan Menderes University Agricultural Faculty Research and Practice Farm as a simple factorial randomized block design in 2008-2009 wheat growing season. The objective of this study was to determine the effects of different seeding rates (200–300–400–500–600 seed/m2) on some bread wheat cultivars (Cumhuriyet-75, Kaþifbey-95, Meta2002 and Sagittario) agronomic, yield and yield components. Agronomic and yield characteristics such as plant height, number of ear per square meter, kernel number per ear, spikelet number per ear, thousand kernel weight and grain yield were investigated. The practice of different cultivars and seeding rates showed a significant effect on many of the agronomic and yield characteristics. Cultivar x seeding rate interaction for the number of ear per square meter was significant and the cultivar x seeding rate interaction mean was 414.3 ear/m2. Number of kernel per ear and spikelet number per ear shows significant impact on the varieties, while the number of kernel per ear and spikelet number per ear reached its highest value at 200 seeds/m2. Among varieties the highest grain yield was obtained by the cultivar Kaþifbey–95 (3606 kg/ha). Different seeding rates indicate no significant effects on the grain yield of wheat. As a result of this study the most suitable sowing rate from 200 seeds/m2 are applicable for the study area. [ABSTRACT FROM AUTHOR]

For Western Turkey (Aegean region) there is a lack of knowledge about the quality potentials of wheat varieties commonly grown in the area. In a field trial we monitored yield, grain quality and rheological properties of 18 wheat genotypes and computed a baking quality index (BQI) to facilitate the detection of high quality varieties. Grain yield ranged from 4047-6406 kg ha-1 in 2004 and from 5167-8099 kg ha-1 in 2005. Crude protein content and farinograph quality number ranged from 8.4% and 27 mm to 14.0% and 135 mm in 2004 and from 9.4% and 33 mm to 13.1% and 98 mm in 2005, respectively. Lines PFAU/WEAVER and CHILERO, such as varieties Golia and Gonen exhibit particularly high Gluten-index values (>80%) that caused favourable rheological properties with farinograph quality numbers of more than 80 mm. The genotypes differed markedly in yield and quality parameters which highlights the need to choose appropriate genotypes for production of high quality wheat in Western Turkey. A close correlation between BQI and farinograph quality number indicates that BQI can be a more valuable tool for detecting genotypes with high bread-making quality, than single quality parameters.

We studied N uptake and distribution in wheat, and the incorporation of nitrogen and carbon into gluten and non-gluten proteins using a double-labelling approach with 15N and 13C. Doses of N-fertilizer were split and applied at emergence, onset of stem elongation, and heading at rates of 280/140/140 mg N pot-1, respectively simulating 90/45/45 kg N ha-1. Five different combinations of N-fertilizations containing no or 10 % 15N were performed. The recovery of 15N added at the stages emergence, stem elongation or heading were 42, 60, and 64 %. Application of 15N at all three stages yielded in 51 % recovery. Remobilisation of straw N was greater for Golia. The 15N concentration in gluten proteins of Golia show higher values than Gonen. The ratio of 15N gluten/15N non-gluten proteins of Golia were higher, which implies a lower non-gluten protein activity during grain filling. The 13C concentration in gluten and non-gluten proteins did not differ between both cultivars. [ABSTRACT FROM AUTHOR]
