Acute Cyanide Intoxication Due To Apricot Seed Ingestion
(Soc Argentina Pediatria, 2024) Talay, Mehmet N.; Gungor, Emre; Orhan, Ozhan
Introduction : Cyanide poisoning, whether it be accidental or intentional, remains a significant danger to adults and children, especially in societies where agriculture is a primary source of income. We examined the clinical follow-up, complications, and results of cyanide poisoning cases that occurred after eating the pits and seeds of plants containing cyanide glycosides, such as apricot kernels and almonds. Methods : Between 01/01/2017 and 01/08/2022, 14 children aged 1-18 years who were followed up with a prediagnosis of cyanide poisoning in our Paediatric Intensive Care Unit (PICU) were retrospectively analysed. Results : Eight of the patients followed with a preliminary diagnosis of cyanide poisoning were female and six were male. The most common admission month was July (42.8%) coinciding with the agricultural season. The most common symptoms at presentation were weakness and fatigue (n = 7). In the PICU, 4 patients presented lip cyanosis; 3, altered level of consciousness. Vomiting, seizure, headache, dizziness and palpitatons were less frequent. Four patients were treated with hydroxocobalamin (Cyanokit (R) ) as an antidote due to acidosis in their blood gases. All patients treated for cyanide poisoning were discharged. Conclusions : Cyanide poisoning should be considered in paediatric patients with suspicious findings, sudden loss of consciousness, increased anion gap acidosis and lactic acidosis. The history of eating the seeds of plants such as apricot and almonds should be investigated .

Ameloriate Effect of Glucose Monohydrate on Nicotine Sulfate-induced Toxicity and Teratogenicity in Xenopus embryos: an Experimental Study
(Koszalin University of Technology, 2023) Pekmezekmek, Ayper Boğa; Emre, Mustafa; Tunç, Erdal; Sertdemir, Yaşar
It is well documented that nicotine causes low birth weight, preterm birth, pregnancy difficulties, lower fertility, inhibition of spermatogenesis, and decreased steroidogenesis and potassium channels conductance of Xenopus oocytes. Lung cancer is the most well-known adverse impact of nicotine. This work used a 96-hour FETAX test to examine how concurrent administration of glucose monohydrate modifies the effects of exposure to nicotine, nicotine sulfate, and/or glucose on ion channels and membrane potential in Xenopus leavis embryos at an early stage of development. In-vitro fertilised embryos were treated with nicotine and glucose alone or in combination for this aim, and the effects of those treatments were then assessed for potential teratogenic effects. At the conclusion of the FETAX technique, the ratios of healthy, abnormal, and dead embryos were calculated, and the length of embryos in each treatment group was assessed. The ratios of abnormal and dead embryos were considerably higher with nicotine treatment alone compared to controls. Compared to the results of the nicotine-alone treatment group, the ratio of aberrant embryos was marginally reduced by concurrent glucose and nicotine therapy. In contrast, the ratio of normal embryos was raised. Additionally, treatments with glucose, nicotine, and Nic+Glu significantly altered the resting membrane potentials of fertilised oocytes (p < 0.001). Our findings indicated that the simultaneous treatment groups that also received glucose had a protective impact on embryos. Such structured, more sophisticated research is required to confirm these findings.
ANALYSIS OF PROMISING BARLEY (Hordeum vulgare L.) LINES PERFORMANCE BY AMMI AND GGE BIPLOT IN MULTIPLE TRAITS AND ENVIRONMENT
(APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH, 2019) Kendal, Enver; Karaman, Mehmet; Tekdal, Sertaç; Doğan, Serap
The development of stable and adaptable new cultivars are based only on positive results obtained from the interaction between the genotype and the environment. Therefore, the study aimed to test the stability and general adaptability of promising barley lines in terms of grain yield and traits in multi-environments. For this purpose, twelve barley genotypes were used in the study. The trials were carried out with four replications in a random design at seven environments in years 2012-13 and 201314. The superior and stable genotypes were identified with GGE biplot and AMMI (Additive main effects and multiplicative interaction) models. The AMMI analysis showed that the major treatment sum of squares was affected by environments (80.6%), GE (14.0%) and genotypes (5.4%), respectively. On the other hand, the first two principal component axes (PCA 1 and PCA 2) contributed to the complete interaction with 88.1%, whereas, PCA 3 and PCA 4 axes only with 12.0%. The GGE biplot indicated that G4 is adaptable for all environments, while Altikat, G2 and G3 showed specific adaptation to E1, E3 and E5, G6, G7 and G8 to E6, respectively. According to both techniques, G2, G3, G6, G7, G8 and Altikat were the best genotypes with high yield, whereas G4 was the best with high yield, and stable and general adaptation. The results of biplot indicated that G4 (ARUPO /K8755//MORA/3/CERISE/SHYRI//ALEL I/4/CANELA/5/HART-BAR) was recommended for release and it was released as HEVSEL in 2017. On the other hand; G7 and G6 were protected as genetic material to use as parent in breeding programs for yield stability and quality respectively.

(Bangladesh Assoc Plant Taxonomists, 2023) Kilic, Murat
Verbascum globiferum Hub.-Mor. and V. lysiosepalum Hub.-Mor. are endemic to Turkey which is a center of endemism for Verbascum species. This study gives the anatomical, palynological and seed micromorphological features of V. globiferum and V. lysiosepalum which grow in Diyarbakir. The xylem elements occupy a large area in the root cross-sections of the species. In stem cross-sections, the upper part of the epidermis cells is surrounded by a separate cuticle layer and the pith region covers a large area. In the leaves, the main vein is shapped as collateral bundle. Pollen grains are tricolporatetricolpate, oblate-spheroidal, and exine ornamentation is reticulate. Seeds are brown and oblong-ovate to prismatic and alveolate. The seed coat ornamentation is irregular with polygonal cells, with densely, distinct vesicles.The capsules are pubescent, covered with stellate and branched hairy or glandular hairs.The seed displayed that substantial taxonomic understanding can be acquired from examining the seed characteristics of Verbascum, particularly at the species level.
Animal Remains of Alaybeyi Hoyuk
(Tubitak Scientific & Technological Research Council Turkey, 2019) Siddiq, Abu Bakar
This paper presents the zooarchaeological observations on animal remains of Alaybeyi Hoyuk unearthed from 2016 and 2017 excavation sessions. Dated to 4721-4553 cal. BC, Alaybeyi stands so far as the oldest archaeological settlement discovered in northeast Anatolia. Therefore, the faunal assemblage at Alaybeyi offers great opportunity to study the status of animals and their relationships with humans in the largely unexplored Kars-Erzurum plateau covering a period from the Chalcolithic to Late Iron Age. Taxonomic and osteometric analyses show that, like the present day, cattle were dominant over caprines, revealing extensive cattle pastoralism in the region for at least about 7 millennia. While caprines too were significant in the subsistence strategy of local humans, there was not any sign of raising pigs. Significant numbers of wild species including carnivores, aquatic mammals, and rodents, as well as resident and migratory birds, were also hunted by Alaybeyi people. Additionally, horse burials, horse cult, dog burials, and a rich number of dog bones present animals as versatile actors in various ritual and symbolic practices at the site.
Anoxybacillus sp. SO B1-Immobilized Amberlite XAD-16 for Solid-Phase Preconcentration of Cu(II) and Pb(II) and Their Determinations by Flame Atomic Absorption Spectrometry
(TAYLOR & FRANCIS INC, 2015) Oral, Elif Varhan; Ozdemir, Sadin; Dolak, Ibrahim; Okumus, Veysi; Dundar, Abdurrahman; Ziyadanogullari, Berrin; Aksoy, Zehra; Onat, Ruken
A new method for the determination of Cu(II) and Pb(II) by flame atomic absorption spectrometry (FAAS) after preconcentrating on a column containing Anoxybacillus sp. SO B1-immobilized Amberlite XAD-16 was developed. The functional groups of Anoxybacillus sp. SO B1 immobilized on Amberlite XAD-16 were characterized in KBr tablets by Fourier transform infrared (FT-IR) spectrometry. Various parameters such as pH, amount of the adsorbent, eluent type and volume, and flow rate of the sample solution were studied. The optimum pH values of quantitative sorption for Cu(II) and Pb(II) were found to be pH 7.0 and 5.0 and Cu(II) and Pb(II) ions could be quantitatively eluted with 5.0ml of 1.0mol L-1 HCI and 10.0ml of 0.25mol L-1 HNO3, respectively. Recoveries of Cu(II) and Pb(II) were found to be 100.9 +/- 1.57% and 100.3 +/- 0.49% (N = 5), the limits of detection of Cu(II) and Pb(II) in the determination by FAAS (3s, N = 10) were found to be 0.8 and 1.6 mu g L-1, respectively. The proposed enrichment method was applied for metal ion determination from water samples such as two parts of Tigris River water in Diyarbakir and Elazig, Lake of Hazar in Elazig, and tap water in Diyarbakir. Furthermore, the accuracy of the proposed method was verified by studying the analytical recovery and by analyzing certified reference material (NCS-DC 73350 leaves of poplar).

(C M B Assoc, 2023) Zhang, Na; Baran, Ayse; Valioglu, Ferzane; Teng, Lei; Atalar, Mehmet Nuri; Keskin, Cumali; Beilerli, Aferin
Verbascum thapsus (Mullein) is a medicinal plant used in folk medicine to treat various ailments. For this study, the biological functions of Verbascum thapsus (VT) methanol extract were determined in vitro. The plant's methanol extract was created through the maceration process. The phytochemical composition of plant extracts was investigated using liquid chromatography-electrospray ionization tandem mass spectrometry. The antioxidant capacity of the extract was determined using the 2,2-diphenyl-1-picrylhydrazil (DPPH radical) and 2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS radical). Cell lines Caco-2 (human colorectal adenocarcinoma cells), LNCaP (Lymph Node Carcinoma of Prostate), and HEK293 (Human embryonic kidney 293 cells) were used to model colon, prostate, and non-cancerous cells. The cytotoxic activity of the plant extract on the proliferation of these cells was determined by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, a tetrazole) assay protocol. VT extract showed moderate DPPH and ABTS radical scavenging activities at 30 mg/ml concentration. With this, VT extract was determined to inhibit acetylcholinesterase (AChE) enzyme and had strong cytotoxic activity on cancerous cell lines. In addition, our findings clearly showed that the plant extract had greater cytotoxic activity on the viability of cancerous cells compared to non-cancerous (Human embryonic kidney cells; HEK293) cells. The current findings showed that V. thapsus might be a promising anti-cancer medication candidate for the treatment of human colorectal adenocarcinoma and colon cancer, as well as a good source antioxidans.

The biological activities of the complexes were also tested. Compounds 2 and 5 were the best complexes at DPPH radical scavenging and reducing power activity at 73.27 % and 0.41 at 200 μg/mL, respectively. The highest antimicrobial activity exhibited by complex 3 as 14 mm inhibition zone against S. aureus. All of the complexes have cleaved the DNA from the double-strand and exhibited three bands on gel electrophoresis. Moreover, cyclic voltammetry studies of the phosphinite complexes were carried out to determine the energies of the HOMO and LUMO levels as well as to estimate their electrochemical and some electronic properties.
Âşık-Maşuk-Rakîb Bağlamında İsmet Özel Şiirinde Aşk
(İstanbul Üniversitesi Türk Dili ve Edebiyatı Bölümü, 2023) Yakut, Emrullah
Nefis, akıl ve aşk itici güçleri arasında şekillenen insanın varoluş macerası, yine insanın dilsel dışavurum ürünleri olan edebî metinlere ve özellikle şiire büyük ölçüde yansımıştır. Bu dışavurum, farklı edebî geleneklerde yüzeysel farklılıklara sahip olmakla birlikte ortak bazı yönleri de ihtiva etmektedir. Klasik şiirde âşık-mâşuk-rakîb üçlüsü arasında cereyan eden aşk temasının İsmet Özel şiirinde de benzer biçimlerde tezahür ettiği söylenebilir. Klasik şiirde mecâzî ve hakîkî aşk arasında çoğu zaman sınırları belirsizleştiren, ayrımları anlamsızlaştıran bir geçişkenlik vardır. Özel’in şiirinde ise ideolojik hedeflerle tensel arzuların iç içe geçtiği, bunlar arasında keskin geçişlerin yaşandığı bir aşk söz konusudur. Klasik şiirde aşk, insanın tekâmül sürecinin önemli bir vasıtasıdır. Benzer şekilde İsmet Özel için de aşk, insanı varoluş atılımına sürükleyen bir harekettir. Diğer yandan klasik şiirde âşık kendi benliğini adeta yok ederek (fenâ) maşuğa kavuşurken İsmet Özel’in şiirinde güçlü bir “Ben” vurgusu dikkat çekmektedir. Ancak bu Ben’in aynı zamanda bir maşuk olarak anlaşılmasına fırsat veren ipuçları, klasik şiirde ve tasavvuf düşüncesinde bilinen âşık-maşuk bütünlüğü çerçevesinde meseleyi daha ilginç bir boyuta taşımaktadır. Bu makale, klasik şiir ile İsmet Özel şiirindeki aşk anlayışını ve âşık, mâşuk, rakîb tezahürlerini mukayeseli bir şekilde ele almayı, benzerlikleri ve farklılıkları tespit ve tahlil etmeyi amaçlamaktadır.
Assessment of renal function in obese and overweight children with ngal and kim-1 biomarkers
(Nutricion Hospitalaria, 2020) Unsal, Velid; Gül, Ali; Yılmaz, Resul; Özmen, Zeliha Cansel; Demir, Osman; Gümüşer, Rüveyda
Aim and background:the incidence of obesity has increased among children, and obesity has been considered an independent risk factor for chronic kidney disease. We aimed to determine the degree of kidney function impairment by evaluating urine neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) levels. Materials and methods: in total, 15 obese, 26 overweight, and 26 control adolescents aged 10 to 16 years were enrolled into the study. Urine samples were evaluated for NGAL and KIM-1 levels using enzyme-linked immunosorbent assay kits. We investigated the association between obesity and related comorbidities with urinary NGAL and KIM-1 excretion. Results: no significant differences were noted between the obese, overweight, and control groups in urinary NGAL and KIM-1 excretion (p = 0.327 and p = 0.917, respectively). In the obese and overweight groups urinary NGAL levels were 50.39 [30.88-74.22] in females and 26.67 [23.24-45.59] in males (p = 0.013). Also, urinary NGAL levels were increased in obese and overweight adolescents with LDL dyslipidemia at 64.12 [30.98-114.32] as compared to those without LDL dyslipidemia: 39.51 [25.59.56.37] (p = 0.024). Furthermore, a correlation was observed between insulin and homeostasis model assessment of insulin resistance levels with the NGAL/creatinine ratio in the overweight group (r = 0.515; p = 0.008, and r = 0.483; p = 0.014, respectively). Such correlation was not found in the obese group. Conclusion: the effect of obesity on renal function could not be determined in children. A longer exposure may be required for obesity-induced disruption of renal function in children. Renal function may be disrupted by dyslipidemia in obese adolescents. Furthermore, obesity impaired renal function in female adolescents. The normalization of these urinary markers as related to urine creatinine should be discussed.

(Progress in Nutrition, 2021) Emre, İrfan; Kürşat, Murat; Emre, Mustafa Yunus; Okkes, Yilmaz
The goal of the present study is to determine some of the biochemical compositions and antioxidant capacities of plant extracts in two endemic taxa for Turkey including T. cadmeum (Boiss.) Heywood subsp. orientale Grierson and T. nitens (Boiss. & Noë) Grierson together with T. polycephalum (L.) Sch.Bip subsp. argyrophyllum (K. Koch) Podlech, and T. parthenium (L.) Sch.Bip. The fatty acids were determined by using gas chromatography, while phenolics, lipid soluble vitamins and sterols were determined by using HPLC and radical scavenging activities, total phenolics, and FRAP were determined spectrophotometrically. It was found that Tanacetum taxa have palmitic acid (C16:0), and stearic acid (C18:0) as major saturated fatty acids and linoleic acid (C18:2 n6), α-linolenic acid (C18:3 n3) and oleic acid (C18:1 n9) as principal unsaturated fatty acids. It was found that Tanacetum taxa had more total unsaturated fatty acid contents (60.24±0.3%- 70.54±0.29%) than saturated fatty acids and it was found that T. parthenium had the highest total essential fatty acid composition (58.65%±0.59%). It was also reported that the omega6/omega3 ratio of T. cadmium subsp. orientale (8.22) differed from other taxa in this study. Also, the present study showed that Tanacetum had the lowest amount of lipid soluble vitamins. On the other hand, catechin was found to be the main polyphenolic compound in this study and it was determined that T. parthenium had the highest catechin (4479.1±5.71 µg/mg) and total phenolic contents (324.91±2.01 µgGAE/mg) in this study. Rutin was only determined in two endemic taxa T. cadmeum subsp. orientale (23±0.91 µg/mg), and T. nitens (5.7±0.27 µg/mg). Also, the naringenin, vanillic acid and caffeic acid amounts of the endemic T. cadmeum subsp. orientale and T. nitens were higher than other taxa in the study. In addition, it was determined that Tanacetum taxa had a high stigmasterol content. However, T. parthenium had a higher ergosterol content (271±2.36 µg/mg). It was also found that T. parthenium has highest D2, α-tocopherol, retinol acetate, ergosterol, and stigmasterol contents among the studied taxa. In addition, the study showed that Tanacetum taxa have strong DPPH and ABTS radical scavenging activities. It was concluded that Tanacetum taxa have potent antioxidant capacity.
Biosynthesis and Characterization of Silver Nanoparticles Using Fig (ficus Carica) Leaves: a Potential Antimicrobial Activity
(Corvinus Univ Budapest, 2019) Acay, H.
Environmentally friendly methods for obtaining nanomaterials see a great interest. In addition to being inexpensive, the easy implementation process and the advantages of synthesis without toxic chemicals are the main reasons of interest. In this study, silver nanoparticles (AgNPs) were successfully synthesized using fig (Ficus carica) leaf extract. The formation and the presence of AgNPs were observed using ultraviolet-visible spectrophotometry (UV-Vis). Peaks with a maximum wavelength of 419 nm are identified in the measurements. Phytochemicals in the extract responsible for functional groups providing reduction and stability were evaluated using Fourier transform infrared spectroscopy (FT-IR) data. The Scanning electron microscopy-Energy Dispersive X-Ray Spectrum (SEM-EDX) analysis showed that the AgNPs were spherical and the elemental composition contained mostly silver. X-ray diffractometer (XRD) results revealed that the peaks 111 degrees, 200 degrees, 220 degrees and 311 degrees belong to the characteristic structure of silver and have a crystal dimension of 17.30 Nm using Debye-Scherrer equation. In thermogravimetric - differential thermal analysis (TGA-DTA) analysis, the degradation temperatures of AgNPs were evaluated. AgNPs showed antimicrobial activity on various microorganisms even at very high concentrations. As a solution to the antimicrobial search, it can be developed in medical industry.
Biosynthesis and Characterization of Silver Nanoparticles Using King Oyster (pleurotus Eryngii) Extract: Effect on Some Microorganisms
(Corvinus Univ Budapest, 2019) Acay, H.; Baran, M. F.
The integration of the principles of green chemistry into nanotechnology has become one of the key issues in nanotechnology research. Metal nanoparticle production, which does not contain toxic chemicals and does not harm the environment, needs to be developed to avoid adverse effects on medical applications. In this study, Pleurotus eryngii (PE) extract was used for preparation of silver nanoparticles (AgNPs). The presence of AgNP was understood that after adding 1 mM silver nitrate (AgNO3) to the fungus extract, the reaction turned from the open yellow to reddish brown. The analysis of samples taken at different times with the UV-Visible Spectrophotometer (UV-Vis) confirms the formation of PE-AgNPs. The Scanning electron microscopy-Energy Dispersive X-Ray Spectrum (SEM-EDX) analysis showed that spherical nanoparticles were formed. X-ray crystallography (XRD), analysis is calculated from Debye-Sherers inequality, in which PE-AgNP synthesized in the study was 18.45 nm in size. It has been demonstrated by using the minimum Inhibitory Concentration (MX) method in which AgNPs have strong antimicrobial activity.

Antimicrobial effects of AgNPs on gram positive Staphylococcus aureus (S. aureus) and Bacillus subtilis (B. subtilis) bacteria, gram negative Escherichia coli (E. coli) and Pseudomonas aeruginosa (P. aeruginosa) bacteria, as well as on fungus C. albicans pathogenic microorganisms It was analyzed by specifying the Minimum Inhibition Concentration (MIC) by microdilution.
Career Aspirations of Refugee Women in Turkey Within the Context of Higher Education
(Palgrave Macmillan Ltd, 2024) Cuhadar, Pinar; Cirkin, Zeynep; Sakiz, Halis
Access to higher education for refugees remains a focal point in discussions concerning human rights. In the aftermath of the Syrian civil war, T & uuml;rkiye has become a significant host country for forcibly displaced individuals. While the Turkish government has implemented an open-door policy toward refugees, the actual participation of women in higher education and the workforce falls short of anticipated levels. Through the lens of Amartya Sen's Capability Approach (CA), this study delves into the perspectives of Syrian refugee women regarding their experiences with higher education in T & uuml;rkiye and investigates how their educational pursuits shape their career aspirations. Employing a qualitative methodology involving semi-structured interviews, this research examines the viewpoints of 40 women enrolled in a state university in T & uuml;rkiye. The findings underscore the role of higher education in enhancing women's career-related skills, fostering their awareness of rights, and predominantly fostering optimistic outlooks toward future labor market engagement.
Cerebrospinal fluid levels of sortilin-1, lipocalin-2, autotaxin, decorin and interleukin-33 in patients with idiopathic intracranial hypertension
(Arquivos de Neuro-Psiquiatria, 2022) Dündar, Ahmet; Arıkanoğlu, Adalet; Özdemir, Hasan Hüseyin; Aslanhan, Hamza; Çevik, Mehmet Uğur
Background Idiopathic intracranial hypertension (IIH) is characterized by increased cerebrospinal fluid (CSF) pressure of unknown cause. It has been suggested that the inflammatory process plays a role in the pathophysiology of the disease. Sortilin-1, lipocalin-2, autotaxin, decorin, and interleukin-33 (IL-33) are among the factors involved in inflammatory processes. Objective To investigate the CSF levels of sortilin-1, lipocalin-2, autotaxin, decorin, and IL-33 in patients with IIH. Methods A total of 24 IIH patients and 21 healthy controls were included in the study. Demographic characteristics of the patients and of the control group as well as CSF pressures were evaluated. Sortilin-1, lipocalin-2, autotaxin, decorin and IL-33 levels in the CSF were measured. Results The CSF levels lipocalin-2, sortilin-1, autotaxin, IL-33 and CSF pressure were significantly higher in the patients group compared with the control group (p < 0.001). Decorin levels were reduced in patients (p < 0.05). There was no correlation between the autotaxin and IL-33 levels and age, gender, CSF pressure, and body mass index. The results of our study showed that inflammatory activation plays an important role in the development of the pathophysiology of IIH. In addition, the fact that the markers used in our study have never been studied in the etiopathogenesis of IIH is important in explaining the molecular mechanism of this disease. Conclusion Studies are needed to evaluate the role of these cytokines in the pathophysiology of the disease. It is necessary to evaluate the effects of these molecules on this process. © 2022.

Changes in Quality Components of Durum Wheat Genotypes Under Temperature Stress and Sufficient Rainfall Conditions During the Growth Period
(Publ House Bulgarian Acad Sci, 2024) Elis, Seval; Yildirim, Mehmet
A combination of genetic makeup and environmental factors determine the quality characteristics of durum wheat. Specifically, environmental stressors, such as extreme temperature fluctuations, can have a substantial impact on the productivity and quality of wheat crops. The effect of terminal temperature stress on yield and quality in durum wheat genotypes grown during 2019 and 2020 seasons was studied. These characteristics include thousand kernel weight, protein content, hectoliter weight, wet gluten content, Zeleny sedimentation value, and grain colour. The first year of the study was warmer than the second, resulting in decreased kernel weight, hectoliter weight, and gluten values, as well as increased protein content and Zeleny sedimentation values. This indicates that temperature stress leads to a higher protein content. The study also showed considerable variation in quality traits among genotypes, with certain genotypes demonstrating greater stability in specific quality traits. Genotype by environment interaction significantly affected grain weight, protein content, gluten content and Zeleny sedimentation. These data indicate that temperature stress plays an important role in determining the quality characteristics of durum wheat. Future studies should focus on mitigating the adverse effects of terminal temperature stress and improving the generation of genotypes with optimal quality traits.

(Fresenius Environmental Bulletin, 2021) Eliçin, Ahmet Konuralp; Öztürk, Ferhat; Kızılgeçi, Ferhat; Koca, Yakup Kenan; Iqbal, Muhammad Aamir
Environmental pollution sed by leaching and gaseous issions from chemical fertilizers necessitates evluation and optimization of organic sources of plant nutrition for soybean production under changing climate scenario. A field study was executed to test different fertilization regimes including chemical fertilizers (CF) (80 kg N and 80 kg P2O5 ha(-1)), sheep barn manure (SBM) (5161 kg ha(-1)). cattle barn manure (CBM) (4878 kg ha(-1)), liquid cattle barn manure (LCBM) (27580 kg ha(-1)) and vermicompost (VC) (4000 kg ha(-1)). The yield attributes, grain yield and fatty acid composition of soybean were taken as response variables in this investigation. The experimental design was randomized complete block design with three replications. The results revealed that SBM and CF recorded the tallest plants and first pod height respectively at both R1 and R5 growth stages, In addition, SBM remained superior for recording significantly higher leaf number at R1 and R5 and node number at R5 stage along with maximum pod number and seeds per pod. The maximum 1000 grain weight and grain yield were exhibited by LCBM which was followed by SBM. In addition, CBM gave the highest protein content while LCBM recorded the maximum oil percentage along with linoleic, mysteric and behenic acid contents, Furthermore, LCBM outperformed other fertilization regimes in terms of palmitoleic, stearic, linolenic and arachidic acids percentages along with oleic: linoleic acid ratio.
