Öğe Assessment of Genotype x Trait x Environment interactions of silage maize genotypes through GGE Biplot(Inst Investigaciones Agropecuarias, 2017) Kaplan, Mahmut; Kokten, Kagan; Akcura, MevlutIn yield experiments conducted at different environments, assessment of Genotype x Environment interactions for investigated traits is a quite significant issue for both agronomists and breeders. GGE biplot analysis was employed in this study to assess the Genotype x Trait, Environment x Trait and Trait Association x Environment of five different traits (silage yield [SY], stem diameter [SD], green leaf weight ratio [GLWR], green stem weight ratio [GSWR], green corn cob ratio [GCCR] and plant height [PH]) of 25 silage maize (Zea mays L.) genotypes grown in six environments. The biplot graphs created in this study to assess Genotype x Trait, Environment x Trait and Environment x Trait correlation interactions were able to explain respectively 86%, 92%, and 83% of total variation of experiments. Current findings revealed that the genotype G18 (Safak), with the greatest silage yield in Genotype Trait biplot (GT biplot) also had the greatest SD; DIY14 (DIYARBAKIR-2014) with the greatest distance from the origin over Environment Trait (ET-biplot) graph was the most distinctive environment; SD with the greatest vector length was the most distinctive trait; DIY14 and DIY15 environments were the best environments for PH, GSWR, SY and SD. It was concluded that GGE biplot method with different perspectives could reliably be used in assessment of silage characteristics of maize genotypes grown in different environments.Öğe Assessment of nutritive value, gas and methane production, fermentation of ensiled mixtures of sorghum-cluster bean(Taylor & Francis Ltd, 2023) Ciftci, Beyza; Kaplan, Mahmut; Akcura, Mevlut; Beyzi, Selma BuyukkilicThis study was conducted to investigate the effects of different mixture ratios of sorghum (S) and cluster bean (CB) on fermentation parameters, nutritional composition, and gas-methane production of mixture silages. Five different mixture ratios (100%S, 75%S+25%CB, 50%S+50CB, 25%S+75%CB and 100%CB) were used in this study. Effects of mixture ratios on entire parameters were highly significant (p <= 0.01). Decreasing ADF and NDF ratios and increasing crude protein, ash and oil contents and condensed tannin levels were observed with increasing cluster bean ratios of the mixtures. However, cluster beans reduced WSC and lactic acid and increased pH, butyric acid and ethanol contents. The lowest Fleig score was obtained from cluster bean silage (100%CB). The lowest gas-methane production was obtained from cluster bean silage and the greatest ME and NEL values were obtained from sorghum silage (100%S). The best OMD values were obtained from sorghum silage and 75%S+25%CB mixture silage. The present findings revealed that a 50%S+50%CB mixture yielded high nutritional composition and good fermentation parameters.Öğe Changes in the Grain Element Contents of Durum Wheat Varieties of Turkey Registered between 1967-2010(Taylor & Francis Inc, 2020) Hocaoglu, Onur; Akcura, Mevlut; Kaplan, MahmutWhile grain yield is the main consideration in developing new cultivars, grain element compositions were also affected by the process of plant breeding. This research aims to evaluate genotypic variation in thousand kernel weights (TKW), percentages of yellowberry kernels (PYK), boron, calcium, copper, iron, potassium, magnesium, manganese, sodium, nickel, phosphorus, sulfur, and zinc contents in the grains of 29 Turkish durum wheat cultivars (triticum durum) released between 1967-2010. Element contents of grain samples are determined with inductively coupled plasma optical emission spectrometry (ICP-OES). Results of 2 years of field trials indicated significant variation between cultivars in terms of all investigated traits (p < .01). TKW of Turkish durum cultivars along with calcium, copper, and sulfur contents are found to be consistently increasing over time with positive correlations to each other. On the other hand, boron and zinc contents of the grain remained unaffected during the process of plant breeding when sodium contents decreased. We suggest that selecting for new germplasm to increase iron, zinc, and phosphorus contents of durum grain will contribute to the nutritional value of its products.Öğe Effects of irrigation intervals and irrigation levels on oil content and fatty acid composition of peanut cultivars(AcademicPres, 2021) Akçura, Sevim; Taş, İsmail; Kökten, Kağan; Kaplan, Mahmut; Bengü, Aydin S.Oil content and fatty acid composition are the most significant quality criteria of peanuts (Arachis hypogaea L.), and these parameters is greatly influenced by irrigation and fertilization practices. A study was conducted to investigate the effects of irrigation intervals and irrigation levels on oil content and fatty acid composition of peanuts, under sandy soil conditions in two consecutive years, using ‘Halisbey’, ‘NC-7’, and ‘Sultan’ peanut cultivars, commonly grown in Turkey. Irrigation levels were arranged based on total evaporation from Class-A pan, and irrigations were applied through drip lines. Irrigation intervals were set as two and four days, and irrigation levels were set as 50% (I50), 75% (I75), 100% (I100) and 125% (I125) of Class-A pan evaporations. Oil content, unsaturated fatty acids (oleic and linoleic acids), and saturated fatty acids (palmitic, myristic, arachidic, behenic and lignoceric acids) were determined. For oil content, treatments were identified as the most appropriate irrigation for a two-day irrigation interval of all cultivars, I100 for four-day irrigation interval of ‘Halisbey’ and ‘Sultan’ cultivars and I75 for four-day irrigation interval of ‘NC-7’ cultivar. Oleic, linoleic, and palmitic acids were the major fatty acids of peanuts. Cultivars exhibited different variations in these fatty acids based on irrigation intervals and irrigation levels. In general, oleic acid contents decreased, but linoleic and palmitic acid contents increased with increasing irrigation levels. The greatest oleic acid contents were obtained from two and four-day irrigation intervals of I50 treatments in ‘Halisbey’ and ‘NC-7’ cultivars and from two and four-day irrigation intervals of I75 treatments of the second year in ‘Sultan’ cultivar. Present findings revealed that for quality peanut production, both irrigation intervals and irrigation levels should be taken into consideration.Öğe Effects of Irrigation Levels on Biochemical Traits of Popcorn Kernels(Springer Science and Business Media Deutschland GmbH, 2023) Kaplan, Mahmut; Taş, İsmail; Ciftci, Beyza; Varol, İhsan Serkan; Akçura, SevimPopcorn, directly consumed as foodstuff, is among the most popular products. Biochemical quality traits of popcorn may exhibit significant variations based on growing conditions. Number of studies about the irrigation-dependent changes in biochemical traits of popcorn kernels is quite limited. This study was conducted to determine the effects of different irrigation levels (50%, 75%, 100% and 125% of depleted water from the field capacity) on protein characteristics (crude protein and pepsin protein digestibility), starch characteristics (total starch, resistant and non-resistant starch, amylose-amylopectin content), oil and fatty acids and mineral contents of popcorn kernels. Experimental results were assessed through variance and biplot analyses. Irrigation levels had highly significant effects on biochemical traits of popcorn kernels. Irrigations increased kernel protein and starch contents and decreased dietary fiber and amylose contents. Linoleic acid contents increased and oleic acid contents decreased with increasing irrigation levels. The greatest palmitic and stearic acid contents were obtained from I100 treatments. Na and Fe contents increased with increasing irrigation levels. The greatest Mg and Zn contents were obtained from I100 irrigation level and the greatest Ca content was obtained from I75 irrigation level. In present biplots generated for visual assessment of the changes in investigated traits with irrigation levels, oleic acid, amylopectin and dietary fiber contents were placed into the same sector with I50 treatment; Zn, stearic acid, palmitic acid and Mg contents were placed into the same sector with I100 treatment; the other traits were placed into the same sector with I125 treatment. Two principle components (PC1 and PC2) explained 96.55 of total variation indicating significance of investigated traits based on irrigation levels. It was concluded based on present findings that biochemical traits, fatty acid composition and mineral contents of popcorn kernels could be improved through the use of different irrigation levels and irrigation levels should be arranged based on soil conditions to improve quality traits of popcorn kernels.Öğe Evaluating the Element Contents of Durum Wheat LandracesPure Lines in Çanakkale Conditions(2020) Hocaoğlu, Fatih Onur; Akçura, Mevlüt; Kaplan, MahmutWheat landraces are often utilized in breeding programsfor their potential to improve the grain qualityof new varieties. Our goal is to evaluate thousand kernel weights (TKW), percentages of the yellowberry kernels (PYK), B, Ca, Cu, Fe, K, Mg, Mn, Na, Ni, P, S and Zn contents of 25 landracesderived durum wheat pure lines collected from the fauna of Turkeyto identify promising candidates.Field trials were conducted in Çanakkale in 2015-2016 and 2016-2017 growing seasons and element contents of pure lineswere determined by using ICP-OES. Differences between durumwheatlandraces werefound statistically significant by all traits (p<0.01). Correlation analysis demonstrated that Ca, Cu and Mg contents of pure lines were positively correlated to each other. Results suggestedavaluable variability amongdurum wheat genotypes in terms of their element contents. Promising candidates were selected for future breeding programs.Öğe Evaluation of silage quality characteristics and nutritive value of oat genotypes(Springer, 2024) Kaplan, Mahmut; Akcura, Mevlut; Kardes, Yusuf Murat; Beyzi, Selma Buyukilic; Ciftci, Beyza; Kokten, KaganThis study aimed to determine the silage characteristics of oat lines developed through a rigorous 10-year selection process. During this period, 100 plants with high biomass yield were meticulously chosen from oat lines obtained from the Louisiana State University gene bank. Researchers designed experiments using an incomplete randomized block format across two growing seasons: 2014-2015 and 2015-2016. Oat plants were carefully harvested at the milk stage, chopped into pieces using a specialized plant chopper, and ensiled in plastic vacuum bags for subsequent analysis. The samples were then stored at room temperature for a period of 60 days. The comprehensive analysis conducted over this two-year research period revealed significant variations in the silage yields of the genotypes, ranging from 5.71 to 24.42 t ha-1. Moreover, notable variations were observed in the content of crude ash (ranging from 3.952 to 9.380%), ADF (ranging from 27.899 to 40.782%), NDF (ranging from 40.688 to 63.999%), crude protein (ranging from 6.673 to 11.470%), dry matter (ranging from 14.954 to 41.817%), pH levels (ranging from 3.812 to 5.668), in vitro gas production (ranging from 49.793 to 67.847 ml), methane production (ranging from 15.036 to 18.442 ml), as well as concentrations of acetic acid (ranging from 0.000 to 0.144%), lactic acid (ranging from 1.974 to 2.599%), butyric acid (ranging from 0.000 to 0.064%), and propionic acid (ranging from 0.000 to 0.306%). The study clearly indicated that many oat lines showed promising silage properties. Consequently, it is inferred that the utilization of high-yield lines in silage production holds considerable potential in providing a valuable feed source for livestock.Öğe Fatty acid and some micro element compositions of cluster bean (Cyamopsis tetragonoloba) genotype seeds growing under Mediterranean climate(Elsevier, 2019) Akcura, Mevlut; Turan, Veysel; Kokten, Kagan; Kaplan, MahmutLimited information is available on fatty acid and mineral composition of cluster bean (Cyamopsis tetragonoloba) genotype seeds grown in Mediterranean climates including Turkey. This study aimed to evaluate seed composition of thirty cluster bean genotypes according to Genotype Trait (GT) biplot analysis. Genotype fatty acid biplot captured 77.6% and genotype micro element biplot captured 65.3% of variation. The results of the present study indicated that oleic acid ranged from 20.07 to 33.62%, linoleic acid ranged from 31.36 to 40.72% in all genotypes. Concentrations of the six micronutrient elements were considerably different in genotypes. Fe and Mn are the most commonly found elements in cluster bean genotypes. Our results depicted that G13 was the most favorable genotype according to fatty acid profile, while G4 and G10 had the highest Fe and Cu contents, and G6 was the most stable genotype according to micronutrient profiles.Öğe Fermentation Quality and Nutritional Traits of Cluster Bean-Maize Mixture Silages(2021) Kaplan, Mahmut; Akçura, MevlütIn present study, effects of different mixture ratios of cluster bean (CB) and maize (M) on silagefermentation and nutritional traits were investigated. Based on dry matter (DM) ratios, maize and cluster beanplants were mixed in five different ratios (100% M, 75% M+25% CB, 50% M+50% CB, 25% M+75% CB and 100%CB). Pure maize, cluster bean and mixture were ensiled for 60 days. Effects of mixture ratios on investigatedtraits were found to be highly significant (p?0.01). Increasing silage DM, ADF (acid detergent fiber), NDF(neutral detergent fiber), lactic acid, gas-methane production, metabolizable energy (ME) and organic matterdigestibility (OMD) values and decreasing pH levels were observed with increasing maize ratio of the mixtures.Increasing silage crude oil (CO), crude ash (CA) and crude protein (CP) content and volatile fatty acids (acetic,butyric and propionic) were observed with increasing cluster bean ratio of the mixtures. Present findingsrevealed that improvements were achieved in DM, pH, nutritional traits and ME of the silages with mixtures ofmaize and cluster bean. It was concluded that 25, 50 and 75% maize ratios in mixtures provided significantcontributions to silage quality.Öğe GREEN HERBAGE YIELD ASSESSMENTS OF MAIZE CULTIVARS THROUGH GGE BIPLOT ANALYSIS METHOD(Soc Field Crop Sci, 2017) Kokten, Kagan; Kaplan, Mahmut; Akcura, MevlutThe present study was conducted to assess green herbage yields of hybrid maize cultivars grown under different environments for two years. GGE biplot analysis method and regression coefficients were used to assess genotype x environment interaction and to identify the most stable cultivars for green herbage yield. Experiments were conducted in six different environments, green herbage yields in the environments varied between 6.0 t da(-1) (E5) and 10.4 t da(-1) (E1) and green herbage yield yields of the cultivars varied between 6.8 t da(-1) (G14) and 10.9 t da(-1) (G18). In GGE biplot analysis, the first two principle component (PC) axis explained about 82.45% of total variation. The genotypes with high PC1 and low PC2 values and regression coefficient of 1.0 were assessed as stable. The cultivar Safak (G18) with such values was identified as the most stable cultivar. The regression coefficient of 1.0 and the greatest green herbage yield proved the stability of that cultivar. The cultivars with higher PC1 and lower PC2 values [30B74 (G2), Seme Kukuruza 877 (G22), ADV 2898 (G24), Wayne (G17), and Safak (G18)] generally had higher green herbage yield than the general average. Safak (G18), 30B74 (G2), Seme Kukuruza 877 (G22), ADV 2898 (G24) and Wayne (G17) cultivars can be use green herbage yield production in south eastern Anatolia will allow the growers to have a profitable production.Öğe GT-biplot analysis of some biochemical characteristics and mineral composition of different sorghum (Sorghum bicolor L.) sprouts(Wiley, 2022) Karaman, Kevser; Kardes, Yusuf Murat; Doran, Turhan; Akcura, Mevlut; Kaplan, MahmutBackground and Objectives The nutritional value of the sprouts has gained interest in recent years because of supplying to fiber, vitamins, minerals, and bioactive compounds such as antioxidants into the diet. The aim of the present study was to reveal the nutritional characteristics of the different sorghum genotypes exposed to sprouting process. For this purpose, some biochemical characteristics and basic mineral profiles of the sorghum sprouts were investigated. Findings According to the results, protein content ranged between 12.17% and 32.24% while the lowest total starch content was determined as to be 3.37% and the highest was 32.71%. Besides, dietary fiber content was in the range of 30.27%-46.42%. Total phenolic content and antiradical activity values of the sprouts were determined as in the range of 3.61-8.42 mg GAE/g and 11.63%-19.51%, respectively. Conclusion The results showed that the sprouting process improved the nutritional quality of sorghum compared to grains and also significant variation was observed among the genotypes in terms of examined properties. Significance and Novelty The results showed that the nutritional parameters especially phytic acid levels of the sorghum grains could be decreased by sprouting process.Öğe Nutrient potential and mineral contents of some vegetable cluster bean genotypes(Wiley, 2020) Akcura, Mevlut; Müftüoğlu, Nuray Mücella; Kaplan, Mahmut; Turkmen, CaferBackground and objectives This study was conducted to determine nutritional traits and mineral contents of green pods of ten different vegetable cluster bean genotypes.

The application of precise irrigation and fertilisation is crucial to ensure the continuity and productivity of sesame production, especially in arid and semi-arid regions. This study aimed to determine the effect of drip irrigation and nitrogen levels on sesame's oil and fatty acid composition. For this purpose, four nitrogen doses (N0: 0 kg ha-1, N30: 30 kg ha-1, N60: 60 kg ha-1 and N90: 90 kg ha-1) and three different irrigation water levels (I50, I75 and I100, which correspond to 50, 75 and 100% evaporation levels from the evaporation of the Class A pan) were applied. The highest oleic acid content (43.06%) was obtained for the I75N90 treatment. In the case of linoleic fatty acid, the greatest value (43.66%) was for I50N0 treatment. The effects of irrigation and nitrogen doses on oleic acid and linoleic acid content were inverse of each other. An increase in applied irrigation water increased the linoleic acid content. However, it caused a decrease in oleic acid content. Increasing the nitrogen dose increased the oleic acid content and caused a decrease in linoleic acid content. Furthermore, this study showed that the I50N60 treatment (50% Epan and a rate of 60 kg N ha-1) is the most effective for achieving high grain and oil yields in sesame cultivation. The results obtained provide practical guidance for farmers in sesame cultivation.Öğe Vetiver ve Soya Karışım Silajının Fermantasyon Kalitesi, Besleme Özellikler İle Gaz-Metan Üretiminin Değerlendirilmesi(2021) Çiftci, Beyza; Akçura, Sevim; Doran, Turhan; Okumuş, Onur; Turan, Ahmet; Kaplan, Mahmut; Kamalak, AdemÇalışmanın amacı farklı oralarda karıştırılan Vetiver (V) ve soyanın (S) silaj fermentasyonu, besinselözellikler ile gaz ve metan üretimi üzerine etkisini incelemektir. Bu amaçla Vetiver ve soya bitkileri beş farklıoranda (100V%, 75%V+25%25S, 50%V+50S, 25%V+75%S ve %100S) karıştırılmıştır. İncelenen tüm özelliklerüzerine karışımın etkisi istatistiksel olarak çok önemli bulunmuştur (p?0.01). Araştırma sonuçlarına göre, silajkarışımındaki soya miktarının artmasıyla kuru madde miktarı, ham protein ve ham yağ oranları artmış, asitdeterjanda çözünmeyen lif (ADF) ve nötr deterjanda çözünmeyen lif (NDF) oranları azalmıştır. Vetiver oranınınartması pH seviyesinde düşüş, gaz ve metan üretiminde, metabolik enerji ve organik madde sindirimderecesinde, ham külde, laktik asit oranlarında artış sağlamıştır. Ancak Vetiverin bir çim türü olmasına rağmensoya ile karışımda iyi bir silaj üretimi için yeterli kuru madde miktarına ve uygun pH seviyesine sahip olmadığıgörülmüştür. Kökleri için yoğun yetiştirilen Vetiverin toprak üstü aksamının yalın silaj olarak değerlendirilmesiveya yeni bitkilerle karışımının yapılması gerekmektedir.Öğe Yemeklik Sakız Fasulyesi Genotiplerinin Yeşil Bakla Verimi ve Yeşil Baklalarının Besin İçeriklerinin Belirlenmesi(2018) Akçura, Mevlüt; Kaplan, Mahmut; Müftüoğlu, Nuray Mücella; Türkmen, CaferProje sebze tipi sakız fasulyesi genotiplerinin tane verimi, verim unsurları ile yeşil baklalarının besinsel içeriğinin belirlenmesi amacıyla yürütülmüştür.

Taub.), also called as guar, is used in industry, animal feeding and green pods are used as a fresh vegetable in some countries. This research is the first study in Turkey carried out nutritional composition. Ten edible guar lines were used as plant material. Green pod yield, yield components (number of pods per plant, single pod weight, pod length and pod width) and nutritional attributes (crude protein, digestible protein and dry matter ratios) of 10 guar lines were investigated with field experiments conducted in two growing seasons (2016-2017). Green pod yields per plant varied between 63.70 and 81.34 g; number of pods per plant varied between 18.78 and 25.98 piece. Single pod weights of the guar lines varied between 2.91 and 3.76 g and differences in single pod weights of the guar lines were found to be significant. Pod lengths varied between 10.86 and 12.43 cm and pod widths varied between 10.32 and 11.31 mm. Crude protein contents of guar lines varied between 14.38 and 17.22% DM and differences were not found to be significant; digestible protein contents varied between 65.40 and 75.25% CP and differences were found to be significant. Dry matter ratios of the green pods varied between 15.92 and 21.16%. Considering the correlations among the investigated traits, it was observed that green pod yields had significant positive correlations with the number of pods per plant, pod weights and pod lengths. Pod weights decreased with increasing number of pods; decreasing dry matter ratios were observed with increasing pod weights and pod lengths. A similar change was also observed in digestible protein contents based on crude protein contents.
