  • The shortest way to diffuse agricultural innovations: A network study in
           the paddy sector in Türkiye

    • Authors: Mehmet AYDOĞAN; Kürşat DEMİRYÜREK
      Abstract: The study revealed the diffusion processes of agricultural innovations and the influential advice sources in the diffusion process by using the network approach. The study sought to answer the questions of how agricultural innovations diffuse in the paddy sector, how agricultural innovations can be delivered to paddy farmers in the most concise form, and what are the typical characteristics of influential advice sources. Data were collected using questionnaires from paddy farmers, input suppliers, rice mills, and other relevant people and organizations in 2017. Social network analysis was used to analyze farmer advice networks, and Ordinal Logistic Regression was used to identify the common characteristics of influential actors in the network. The research results indicated that the farmers were a bridge between innovation creators and other farmers. The local pesticide dealers were the intermediary position among the paddy farmers with the innovation creators. Collective action, membership in agricultural organizations, social status, and project experience were influential factors in being an advice source. The study found that agricultural innovations in the paddy sector can diffuse most quickly from innovation creators to local pesticide dealers and farmers.

  • Effects of different industrial cannabis (Cannabis sativa (Linnaeus 1753)
           (Cannabaceae)) genotype extracts on Diuraphis noxia Kurdjumov, 1913 Myzus
           persicae Sulzer, 1776 and Aphis fabae Scopoli, 1763 (Hemiptera: Aphididae)
           

    • Authors: Şeyda ŞİMŞEK; Ali KAYAHAN, Gamze PEKBEY, Güngör YILMAZ, İsmail KARACA
      Abstract: In this study, the effect of methanol extracts of three different genotypes (Narlısaray, Kavacık, Maltepe) of Cannabis sativa L. on Diuraphis noxia Kurdjumov, Myzus persicae (Sulzer) and Aphis fabae (Scopoli) (Hemiptera: Aphididae) were investigated. In the first stage of the study, 10% concentrations of each cannabis extract were applied on the 2nd and 3rd nymphal stages of aphid species by spraying method. After the end of 24 - 48 and 72 hours of the applications, the alive and dead individuals were recorded and mortality rates were determined. In the second stage, the genotype with the highest effect was used in dose-death trials and LD50 and LD90 values at different doses (2.5%, 5%, 7.5% and 10%) were specified. In the census after 72 hours, Narlısaray genotype showed the highest mortality rate with 54.04% on D. noxia. While the effect of Kavacık genotype on M. persicae was found as 23.13%, the highest toxicity record of the same genotype was determined on A. fabae (as 91.76%). According to the dose measurement studies of Kavacık genotype on A. fabae, LD50 and LD90 values were calculated to be 0.33 and 0.110 (mg/individual), respectively. At the results of study, it has been observed that extracts of different genotypes of the industrial cannabis plant are found effective on aphid species and it is thought that they can be used in controlling of these pests.

  • Some physical properties of bitter gourd (Momordica charantia L.) seeds
           and kernels

    • Authors: İsmail BOYAR; Tugce OZSAN, Can ERTEKİN, Ahmet Naci ONUS
      Abstract: A noteworthy member of the Cucurbitaceae family, the bitter gourd (Momordica charantia L.) is a slender, vine-like annual summer vegetable. Despite the health promoting features, it is among the neglected vegetables in terms of both production values and scientific studies. The current study was aimed to assess some physico-mechanical properties of bitter gourd seeds and kernels viz., sizes, geometric shapes, angle of repose, densities, 1000-seed and kernel weight and, coefficient of friction on several surfaces (aluminum, chrome, iron, plastic, rubber, cardboard, glass and MDF wooden panel) in order to determine to important parameters to design seed sowing machines the materials to be used in storage and their design, the screening/separation/classification processes and the processing of bitter gourd into a commercial product. It has been observed that the seeds of bitter gourd have similar geometrical properties with the seeds of melon, watermelon, squash and cucumber from the Cucurbitaceae family. While closer values were observed in terms of length and width, it was determined that the seeds of bitter gourd were thicker. The lengths, widths, and thicknesses of these seeds/kernels with a moisture content of 16% (w.b.) according to the wet base were found to be 14.176/11.517, 7.562/5.922, and 4.076/2.815 mm, respectively. The angle of repose, thousand grain weight and true density of seeds/kernels were found 28.467/26.982°, 202.931/118.359 g and 0.919/1.659 g/cm3 respectively. Obtained results most likely can serve bitter gourd to be grown in large amounts in different part of the world where the climate is suitable for growing.

  • The sensitivity of radish cultivars to high temperatures during
           germination and seedling growth stages

    • Authors: Gamze KAYA
      Abstract: A laboratory experiment was conducted at constant temperatures of 20, 23, 26, 29, 32, 35, 38, and 41℃ to identify the response of six radish cultivars with different root sizes and colors to high-temperature stress during germination, emergence, and early seedling growth stage. Also, the optimal temperature was determined by calculating the relationship between seedling length and temperature via a polynomial regression model. The results showed that no seed germination was detected at 41℃, while emergence and seedling growth were not observed at 38℃ and above. Similar germination percentages, mean germination time, and germination index were obtained between 20℃ and 35℃. The root length reduced at 32℃ and it was more sensitive to high temperatures than shoots because the root/shoot length ratio showed a decreasing trend by increasing temperatures and longer root length was recorded at lower temperatures than 32℃. There were genotypic variations among radish cultivars for temperatures and ‘Kırmızı İnci’, ‘Beyaz İnci’, and ‘Siyah İnci’ produced a better performance than the others under high temperatures. The regression analysis predicted the optimal temperatures as 21.5℃ and 22.6℃ for root and shoot length, respectively. This study indicates that high temperatures inhibited seedling growth rather than seed germination performance of radishes.

  • Comparative life history and demographic parameters of Ephestia kuehniella
           Zeller (Lepidoptera: Pyralidae) on maize and oat flours

    • Authors: Ali GÜNCAN; Şaziye KARAYAR, Yunus Emre ALTUNÇ
      Abstract: Ephestia kuehniella Zeller (Lepidoptera: Pyralidae), Mediterranean flour moth, is a major pest of stored food products, causing significant economic losses. Understanding the life history and population dynamics of E. kuehniella is crucial for developing effective pest management strategies and improving the sustainability of the food industry. In this study, we conducted an age-stage, two-sex life table analysis of E. kuehniella reared on maize and oat flours. The aim of the study was to compare the demographic parameters of the E. kuehniella populations reared on the two different types of flour including maize in laboratory conditions at 26 ± 1 °C, 60 ± 5% R.H., and a 16:8 (light: dark) photoperiod. Our findings suggest that while the flour type had a minor effect, there was no significant impact on the developmental time, survival rate, fecundity, and population growth rate of E. kuehniella. However, adult female longevity was significantly longer in the maize flour group compared to the oat flour group. The pre-adult survival rate was higher in the maize flour group (83%) than the oat flour group (72%). Additionally, our results indicate that fecundity of the E. kuehniella was slightly higher on oat flour than on maize flour, while the population growth rate was similar on both flours. Our results demonstrated that the larvae fed with maize flour consumed a significantly higher amount of flour (394 mg) than those fed with oat flour (278 mg). Furthermore, after 120 days of simulation the population growth projection of E. kuehniella was twice as high in oat flour compared to maize flour. These findings suggest that both maize and oat flours are susceptible to E. kuehniella infestation, which has important implications for the development of effective pest management strategies and the sustainability of the food industry.

  • Experimental investigation of parametric changes in seepage time and
           length into the subsoil of hydraulic structures

    • Authors: Damla YILMAZ; Betül Sena ÖKSÜZ, Egemen ARAS, Bilge ÖZDOĞAN CUMALI, Semih NEMLİOGLU
      Abstract: Dams and hydraulic structures are built on rivers in order to protect water resources due to global warming, to collect surface waters to provide drinking water and/or irrigation water, to prevent floods and to establish hydroelectric power plants. Dams, for example, are hydraulic structures that have more or less positive or negative environmental interactions on surface water and groundwater. One of the environmental interactions of dams and similar hydraulic structures is the seepage of accumulated water in its reservoir from upstream bottom of the dam. This seepage can affect the level and location of groundwater, reduce the accumulation of water in the reservoir, and cause piping in the ground below the construction of the dam body. In order to control the seepage, the methods of increasing the seepage length by using sheet pile and clay blanket on the dam foundation are frequently used. In this study, in the physical laboratory model, the variations in the seepage lengths that occur under the hydraulic structure section in the soil with two different grain diameters of 0.85 mm and 1.5 mm, depending on the dam structure, soil and barrier structures (sheet pile and upstream clay blanket), were experimentally investigated. As a result, it was determined that the seepage occurs less in the soil with a smaller grain diameter of 0.85 mm, the smaller the soil particle diameter has a reducing effect on the seepage, and the use of sheet pile increases this effect positively. In addition, it has been determined that the clay blanket in the upstream is effective compared to the general conditions, but the use of sheet pile provides the most efficiency.

  • Determining the temporal and spatial variation of the land cover according
           to CORINE(1990-2018) in the basin of Kesis Stream (Southern Türkiye)

    • Authors: Fatih KARAOSMANOGLU
      Abstract: Human has interfered with nature in many different ways and tried to benefit from it since the dawn of time. Especially during and after the Industrial Revolution, human pressure on nature exploded. Due to this increasing pressure, global warming and climate change have occurred, resulting in events such as landslides, floods, and droughts. In this study, CORINE land cover data were used to determine the temporal variation of land use/cover (1990-2018) in the basin of Kesis Stream. CORINE land use/cover data, which was created for periods of ten and six years (1990-2000-2006-2012-2018), was processed through geographic information systems (GIS) and presented with various figures, graphics, and tables. Accordingly, the discontinuous urban fabrics in the basin covered an area of 1.09 km2 in the 1990-2000 period, while they covered an area of 1.35 km2 with a partial increase in 2018. The basin is mainly covered with forest and agricultural fields. While the forest lands (1990-code; 311, 312, 313, 324) covered an area of 410.29 km2 in 1990, they gradually increased to 446.39 km2 in 2018. While the agricultural lands covered an area of 368.04 km2 in 1990 (code-1990; 211, 212, 242, 242), they decreased to an area of 326.85 km2 in 2018 a significant decrease. According to these results, it can be asserted that the morphological structure of the basin, with steep and deep valleys has restricted adverse human activities and reduced forest destruction in the last 28 years with the implementation of nature protection laws.

  • Technical efficiency of agroforestry production technology among
           smallholder farmers in Kaduna State, Nigeria

    • Authors: Olugbenga Omotayo ALABI; Godbless Friday SAFUGHA
      Abstract: This study evaluated technical efficiency of agroforestry production technology among smallholder farmers in Kaduna State, Nigeria. Multi-stage sampling technique was adopted. A total sample size of 120 smallholder agroforestry farmers was used. Primary data were collected with the aid of structured and well-designed questionnaire. Analytical tools used were: descriptive statistics, farm budgeting techniques, financial analysis, stochastic production frontier model, and principal component model. About 85% of agroforestry farmers were male, while 15% were female. Also, 87.50% of agroforestry farmers were less than 50 years of age. The mean age was 45 years. Furthermore, 85% of agroforestry farmers had formal education and were literate. The household sizes were large with mean value of 6 members per household. The agroforestry systems practiced include: alley farming, shelterbelts, wind breaks, home gardens, api-silviculture, aqua-forestry, retaining tree on farm land, taungya systems, farmed parkland, and silvo-pasture. The result of the farm budgetary technique show that agroforestry farming was profitable among the smallholder farmers in the study area. The result of the maximum likelihood estimates shows that the significant factors influencing output of agroforestry production technology were: seed input (P<0.05), farm size input (P<0.01), fertilizer input (P<0.10), labour input (P<0.10), and chemical input (P<0.01). The significant factors influencing technical inefficiency of agroforestry production technology were: gender (P<0.10), marital status (P<0.01), education level (P<0.01), experience in agroforestry production (P<0.01) and size of households (P<0.10). The average technical efficiency score obtained by the smallholder agroforestry farmers was 40.18%. The constraints facing agroforestry farmers include: lack of training and capacity building, inadequate extension officers, lack of improved seeds, lack of credit facilities, lack of fertilizers, and lack of agroforestry tree seedlings. The study recommends that agroforestry tree seedlings should be made available to farmers, credit facilities should be provided for easy access to agroforestry production technologies, extension officers should be employed, and improved seeds, fertilizers should be provided for increased productivity.

  • Determination of effective surface sterilization protocol in in vitro
           tissue culture for Giant Snowdrop (Galanthus elwesii Hook) bulbs

    • Authors: Çağlar KAYA; Tolga SARIYER, Esra ŞAHİN
      Abstract: Giant Snowdrop (Galanthus elwesii Hook) is a species of snowdrop belonging to the Amaryllidaceae family. In this study, the deformation rates of the bulbs was calculated as % (percent). For sterilization G. elwesii bulbs were sterilized at different concentrations (1, 3, 5, 7, 9, 11 and 13 %) of sodium hypochlorite (NaOCl) for 5, 10, 15, 20, 25 minutes. The bulbs were rinsed with sterile distilled water 3 times for 5 minutes and then transferred to the MS medium. Contamination rates in MS nutrient medium were determined as percent (%) after 7 days. Deformation was not observed in the bulbs sterilized with 1 and 3% sodium hypochlorite solution however 100% contamination was detected. The most effective surface sterilization was obtained by soaking in 9-11% sodium hypochlorite solution for 5 and 10 minutes. As the sodium hypochlorite concentration and the application time increased, the surface sterilization of the bulbs increased, but the deformation rate of the scaly leaves of the bulbs increased due to this increase.

Biplot analysis has become widespread in recent years as an important statistical technique for plant breeders and those working in agricultural research. This study was carried out according to Randomized Complete Block Design with 18 upcountry and 2 abroad registered varieties in Muş location in 2022 year. Yield and quality components were investigated. According to the results of variance analysis, it was determined that there were statistically significant differences at the level of 1% among the varieties in terms of all the traits examined. According to the average data obtained in the study; bifurcation varied between (%) 5.4-17.8, leaf yield 13.54-24.28 t ha-1, root yield 73.42-93.57 t ha-1, biological yield 90.29-118.26 t ha-1, sugar content (%) 16.2-19.0, plant juice purity 82.39- 88.10%, dry matter (%) 16.4-20.1, α-amino N (mg 100g-1) 0.0405-0.0498 and ash (%) varied between 2.49-3.35. According to the results of the research, in terms of root yield, G10 no and G14 no varieties came to the fore in terms of the most stable and examined traits. G12 no variety came to the fore in terms of sugar yield and G19 no variety in terms of sugar content. When the average data of all examined traits are evaluated together, G10, G11 and G14 no varieties are considered as the most stable varieties. However, varieties with high root yield, sugar content and sugar yield are the primary preferences of growers in sugar beet production. When all the data of the varieties used in the research are evaluated together; G2, G4, G8, G10, G11, G12, G14, G15 and G19 no varieties can be recommended for Muş ecological conditions. However, it was concluded that the study should be carried out in the following years for more decisive recommendations.

           turkish yoghurt, cheese, kefir samples as a probiotic candidate

    • Authors: Nazan TOKATLI DEMİROK; Mehmet ALPASLAN, Seydi YIKMIŞ
      Abstract: Lactic acid bacteria which are important for production of fermented milk products contain may strains called Lactobacillus, Streptococcus, Lactococcus and Leuconostoccus. As a result, lactic acid bacteria are called ‘milk-souring (fermenting)’ organisms. In addition to the fermentation abilities of Lactobacillus spp., it is important for aroma, texture and acid formation and comprises the most important group of lactic acid bacteria. Their critical importance comes from their metabolic capacity and probiotic features. In this research, yogurt, cheese and kefir samples were collected from cities in Turkey and used to isolate. Isolates were identified phenotypically and genotypically characterized. The probiotic features antibacterial activity against Staphylococcus aureus ATCC6538, Listeria monocytogenes DSM12464, Escherichia coli ATCC 25922, Enterococcus faecalis ATCC51299, and Salmonella Enteritidis ATCC 130762; bile and acid salt tolerance, susceptibility to chloramphenicol, erythromycin, penicillin G, gentamicin, vancomycin, streptomycin, kanamycin, and tetracycline of isolates were determined. Isolates, were identified as Lactobacillus paracasei subspecies (subsp.) paracasei, Lactobacillus delbrueckii subsp. bulgaricus, Acetobacter ghanensis, Acetobacter fabarum, Acetobacter subsp., Leuconostoc pseudomesenteroides, and Leuconostoc mesenteroides subsp. mesenteroides. Some isolates were tolerant of acid and bile salt, some strains were resistant to antibiotics, and some could inhibit pathogens. In this study, isolates were determined to have probiotic features. As a result of the study, it was determined that some isolates showed probiotic properties and had strong antibacterial activity. Isolates can be use as natural alternative in infections.

  • Biotechnological potential of apple pomace for value-added products

    • Authors: Sıla SÖZGEN; Serpil TAKAÇ
      Abstract: Agri-food processing waste and by-products are important to be valued in an integral unit to the main process. This study focused on showing the potential valorization of apple pomace as substrate towards valuable products by a biotechnological mean. Apple pomace was fermented by B.subtilis at 37 °C, 150 rpm, and 72 h. Reducing sugars, total phenol content and α-amylase activity were followed throughout the fermentation. The results showed that B.subtilis assimilated apple pomace sugars and stimulated the release of sugars into the medium during fermentation. α-amylase activity detected in the medium also indicated the degradation of pomace by B. subtilis. However, the total phenol content was found to be low. The α-amylase activity at 24th h was 29.6% higher when the fermentation initiated with a former fermentation medium than that of started with the inoculum based on agar and liquid incubation media. Overall results showed –for the first time- that apple pomace can be valued towards α-amylase activity, reducing sugar and total phenol content by the activity of B.subtilis cells.

  • Investigation of generative high temperature tolerances of some cotton
           (Gossypium hirsutum L.) varieties

    • Authors: Yusuf Güzel DEMİRAY; Remzi EKİNCİ, Adem BARDAK
      Abstract: The potential of cotton genotypes to form buds, flowers and bolls is not sufficient to achieve cotton seed yield targets. Despite global warming buds, flowers and bolls that mature in cotton plants must be successfully transformed into products. However, this is related to the generative tolerance of the genotype to high temperature. In study aims to scan the negative effects of high temperature stress on the generative development on cotton varieties registered in Turkey in the last 10 years. The experiment was established in the GAP International Agricultural Research and Training Center trial field in 2020, with 4 blocks according to the Augmented design. Six standards (Tamcot Spnhix, SJU86, AGC208, ST468, ST474, Carmen) and 88 cotton varieties registered in Turkey National Variety List were used as trial material. In this study, high temperature pollen vitality stress index (HTPVSI) and high temperature shedding stress index (HTSSI) properties were investigated. According to the results of the experiments we conducted, it was determined that the HTPVSI values ranged between 0.17-1.26, the HTPVSI averages of the standards were 1.17, and the HTPVSI averages of the genotypes were 0.99. It has been determined that HTSSI values vary between 0.30-1.71. It was determined that the mean HTSSI values of the standards were 0.89 and the genotypes were 1.00. It was determined that there was a wide variation among the genotypes screened for generatively high temperature stress. Using HTSSI and HTPVSI features is recommended as a selection criterion since it is an important trait for screening genotypes in terms of tolerance or sensitivity to generative high temperature stress in cotton plants. In our study, the results were not similar to each other in terms of HTPVSI and HTSSI traits, due to the low share of flower shedding after applying HTSP (High Temperature Shock Practice: 96 hours of uninterrupted exposure to high temperature during generative periods) in the shedding rate. When the examined HTSSI and HTPVSI traits were examined together, no cotton genotypes were found to be generatively tolerant. In terms of sensitivity of genotypes to high temperature, 18 cotton genotypes were found in the medium tolerant group and 25 cotton genotypes were found in the sensitive group.

  • The biological activity features and mineral element analyses of some
           Inula L. species exhibit natural spread in Mugla (Turkiye)

    • Authors: Hande KESİM; Mahmut YILDIZTEKİN
      Abstract: Medicinal and aromatic plants (MAPs) are rich in nutrients and alternative therapies. Some MAPs become industrial crops that are grown around the world for their nutritional and medicinal properties. The aim of this study was to assess the relationship between mineral nutrient content and antioxidant properties of Inula viscosa (I. viscosa) and Inula graveolens (I. graveolens) species found in the Köyceiz region of Muğla province. In this study, the antioxidant activity values of the extracts obtained were found to be the highest in methanol and acetone extracts of Inula viscosa. In contrast, the lowest in hexane extracts of Inula graveolens species. It was determined that the methanolic extract of I. viscosa had the highest 137.1 (µg PE /mg) a and the hexane extract of I. graveolens L. had the lowest 22.40 (µg PE /mg) total phenolic content. On the other hand, the mineral content of the species (macro (%): N, P, K, Ca, Mg, and micro (ppm): Fe, Mn, Zn, Cu, B) were also taken into consideration. As a result, it was observed by the analysis that there was a significant interaction between the antioxidant activity values of the species and their mineral nutrition. The antioxidant activities of plants are influenced by a variety of factors. The plant's activity is influenced by a number of variables, including the time of harvest (flowering, seed formation, etc.), extraction technique, solvent polarity, fresh or dry plant material, mineral nutrient content, and method. It is thought to broaden perceptions of these plants beyond their nutritional value by putting the antioxidant effects of the plant on a scientific basis. In this study, Inula graveolens L. and Inula viscosa L. demonstrated the potential of plant extracts as a readily available source of natural antioxidants, potential food additives, pharmaceuticals, and pharmaceutics.

           learning method for robotic seedling selection system

    • Authors: Erhan KAHYA; Fatma ÖZDÜVEN
      Abstract: Lettuce is a type of vegetable that is widely cultivated and consumed in our country and in the world. The seedling period, which is the beginning of production, is the most sensitive time for the plant. Starting production with healthy seedlings is an important parameter for quality and efficient production. In this study, a sample program for automatic seedling selection was developed for a robotic system to be used in seedling production. With the developed program, it was aimed to select seedlings with the same degree of maturity in multi-well pots. In this study, Yolo5n was used for the training model. A learning system was established on two types of lettuce (curly salad), and red curly lettuce leaf (lolo-rosso) seedlings. As a result of the training, F1 score was found as 83%; Precision was 100%; Recall was 95%; Precision Recall was 86.7%. The learning rate was 0.0005 for all given images. In view of these data, positive results were obtained for the mentioned method in seedling selection.

           aqueous extract: anticancer and antimicrobial properties

    • Authors: Polat İPEK; Mehmet Fırat BARAN, Reşit YILDIZ, Abdulkerim HATİPOĞLU
      Abstract: This study was carried out to synthesize silver nanoparticles (AgNPs) from Arum dioscoridis (AD) leaf extract and to investigate the cytotoxic and antipathogenic effects of them. The plant material had a reducing and stabilizing effect on the synthesized nanomaterial. During the plant-mediated synthesis of nanomaterials, no substances that would cause environmental pollution were used. For the structural characterization of AD-AgNPs, Ultraviolet-visible (UV-vis) Spectroscopy, Field Emission Scanning Electron Microscopy (FE-SEM), Electron Dispersive X-ray (EDX) Spectroscopy, Fourier Transform Infrared (FT-IR) Spectroscopy, Transmission Electron Microscopy (TEM), X-ray Diffractometer (XRD), Atomic Force Microscopy (AFM) and Zetasizer analyses were performed. The produced AgNPs showed maximum surface plasmon resonance at 431.67 nm and had mostly spherical morphology. The zeta potential value of the nanomaterial was -9.76 mV and the average powder crystal size was 31.48 nm. The minimum inhibitory concentration (MIC) values (mg/L) of AD-AgNPs on Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, and Candida albicans were 0.25, 2.00, 0.125, 4.00, and 1.00, respectively. After 24 and 48 hours of application by MTT [3-(4,5-dimetiltiazol-2-il)-2,5-difeniltetrazolium bromid] assay, the half-maximal inhibitory concentrations (IC50: μg/mL) of AD-AgNPs on human colon adenocarcinoma cell (CACO-2), human breast cancer cell (MCF-7), glioblastoma multiforme cell (T98-G), and healthy human umbilical vein endothelial cell (HUVEC) lines were determined as 2.977, 2.801, 5.694, 4.392; 2.115, 2.300, 2.612, 4.091, respectively.

  • Pollution indices assessment of metal concentrations in Karabuk soil
           samples

    • Authors: Naim SEZGİN; Saidou KINDA, Uğur Emre TEMELLİ, Nazan SEZGİN
      Abstract: Soil pollution refers to the contamination of soil by harmful substances that can have adverse effects on plant and animal life, it also negative affects the health-being of humans. The sources of soil pollution include industrial activities, agricultural practices, mining and transportation activities. The contaminants in soil can include heavy metals, pesticides, herbicides, fertilizers, petroleum products, and other chemicals. These contaminants can seep into the soil and accumulate over time, making the soil unsuitable for agriculture or other uses. Heavy metals are a significant concern in soil pollution due to their persistency and potential harm for living organisms. Therefore, it is essential to evaluate metal contamination in soil using ecological risk indices to protect human health. This assessment can help identify potential risks and enable effective management of contaminated sites. This study aimed to assess of the metal pollution levels, including Arsenic (As), Cobalt (Co), Chromium (Cr), Copper (Cu), Nickel (Ni), Lead (Pb), and Zinc (Zn), in soil samples from Karabuk using various ecological risk indices. These indices included the geo-accumulation index (Igeo), enrichment factor (EF), contamination factor (CF), contamination degree (Cd), pollution load index (PLI), and potential ecological risk (PERI). Furthermore, statistical techniques such as correlation and factor analysis were employed to determine the underlying sources responsible for these metals. Based on the results of the Cd, PLI, and PERI, it was found that the soil at T7 exhibited a very high degree of contamination, was moderately to highly polluted, and posed a moderate ecological risk, respectively. The results of the pollution indices suggest that the sources of pollution in the Karabuk soil samples are anthropogenic, meaning they are a result of human activities like industrial processes and improper waste disposal.

  • Total secondary metabolites and heavy metal profile of some medicinal
           plants frequently consumed as winter tea

    • Authors: Yusuf KARAGÖZOĞLU; Naci Ömer ALAYUNT, Akif Evren PARLAK
      Abstract: In this study, sage (Salvia officinalis L.), linden (Tilia platyphyllos Scop.), and daisy (Matricaria chamomilla L.) herbs, which have rich phytochemical content and are frequently consumed in winter months for medicinal purposes, were obtained from three different herbalists located in Bingol and investigated in terms of their heavy metal contents, total flavonoid, total anthocyanin and total polyphenol contents. Some of the heavy metal (Cr, Fe, Co, Ni, Cu, Zn, As, Hg, Pb) contents of the collected herb samples were determined by ICP-MS. Total flavonoid, total anthocyanin and total polyphenol contents were determined by analyzing spectrophotometric methods. While the total phenolic content was found the most in sage (S1) ethylacetate and methanol extracts (760.1±2.0, 410.33±1.5 mg GAE/g), it was found the least in linden (L1, L3) hexane extracts (6.66±.1.3, 8.35±0.8 mg GAE/g). It was determined that total flavonoid content and total anthocyanin contents were higher in sage (S1) ethylacetate (294.31±2.1 mg CE/g and 291.31±2.1 mg MvGE/g), sage (S2) methanol (375.0±1.9 mg CE/g and 139.01*±2.0 mg MvGE/g) extracts, and less in linden (L1) and daisy (D1) hexane extracts respectively. It was determined that Cr and Cu metals were among the values suitable for consumption in terms of health in all samples except the chamomile (D1, D3) samples, and Zn metals were among the values suitable for consumption in all samples except the linden (L2) sample. Furthermore, the toxic metal Cd (0.05±0.00- 0.09±0.00 μg/g) in daisy (D1, D3) samples, as well as the other toxic metal Pb (4.50±0.01-6.43±0.01 μg/g) in sage (S1,S2,S3) and linden (L1,L2,L3) samples, were found to be among the values suitable for consumption in terms of health. As a result, when the total anthocyanin, polyphenol and flavonoid contents were compared in all groups it was found that sage had the highest value in ethyl acetate extract. Additionally, Cu and Ni values of sage, and Fe and Pb values in both sage and linden were within safe limits in terms of health. They are of utmost importance in terms of supporting the daily mineral intake. However, As, Pb, and Hg were found to be toxic in daisy extract. This result can be shown as a result that the daisy will be a bioaccumulator. Therefore, consumption of daisy tea should be limited.

  • Chemo-enzymatic synthesis of chiral precursor molecules with chiral ring
           hydroxyenone and acetoxyenone structures

    • Authors: Hatice BECEREKLİ; Şaziye Betül SOPACI
      Abstract: A biocatalytic transformation has the potential to perform organic reactions that are quite challenging to achieve with synthetic organic chemistry. They also catalyze these reactions with a chemo and enantio selective manner. The discovery and development of new chemoenzymatic methods for the synthesis of these chiral structures is essential to the production of a wide range of bioactive compounds. In this study, two important pharmaceutical precursors were synthesized chemoenzymatically and subjected to biocatalytic conversions with different dehydrogenases. One of these compound is an α-acetoxy enone structure 4-methoxy-2-oxacyclohex-3-enyl acetate and the other is an α-hydroxy ketone 6-hydroxy-3-methoxycycyclohex-2-enone. To obtain these pharmaceutical precursors, 3-methoxy-cyclohex-2-enone was prepared using 1,3-diketone as a starting material. After obtaining this material, α-acetoxy enone was synthesized by chemical acetylation and α-hydroxy ketone prepared by enzymatic deacetylation. The structure of these products was elucidated by NMR analysis. In addition, biocatalytic reduction reactions involving the enzymes galactitol dehydrogenase (GatDH), shikimate dehydrogenase (SDH) and diaphorase were carried out with these products.

  • Enabling circularity for food safety: the rooftop farming model

    • Authors: Tufan ÖZSOY
      Abstract: Population growth, environmental change, urbanization, consumption patterns, waste, the global political climate, conflicts, and infectious diseases all exert a strain on global food security. Access to sufficient and nutritious food is becoming increasingly problematic, particularly for individuals living in less developed and developing countries. More individuals are becoming aware of the significance of developing a "Green Economy" approach to ensure global food security. A multifaceted strategy is required to ensure global food security. This study emphasizes the need for regional self-sufficiency for the transition to a green economy, and as a model proposal, it is suggested that it would be beneficial to encourage and develop farming operations on the roofs of residential, commercial, and public housing in urban regions. Rooftop farming, as one of the urban agriculture practices, can be utilized as a strategic instrument to achieve a variety of key aims, including enhancing the local economy, reducing inequality, internalizing responsible production and consumption by society, improving the quality of urban life, and more. Furthermore, because of the novel production processes seen in urban agriculture, circularity in production and consumption, a key component of the transition to a green economy, can be realized. "Self-sufficiency" is one of the concepts underlined in this study. The study also includes real cases highlighting the potential benefits of rooftop farming.
