Sertaç Güngör | Sabriye Özer | Murat Seyhan
Today, the rapid increase in urbanization and the concentration of population density in urban centers have increased the need for individuals to be in touch with nature. In this context, urban use areas such as urban parks play an important role in meeting the physical and social needs of teenagers. Parks are not only spaces that encourage physical activity, but also spaces that increase social interaction, strengthen community ties and support physical activities. Ihlamur Park in Konya is an important living space where teenagers show great interest, offering various activities and social opportunities. However, detailed information on the purposes for which teenagers use the park and which features of the park encourage this use has not been fully identified. The aim of this study is to examine the purposes of the use of Ihlamur Park by teenagers and to identify the features of the park that encourage physical activity and social interaction. For the research, 116 teenagers were surveyed face-to-face on the basis of the law on the protection of personal data and voluntary participation of park users by visiting the area on random days on weekdays and weekends. The survey was carried out with the approval of the Ethics Committee of Selçuk University, Faculty of Architecture and Design. By determining the level of use of teenagers, it is the preparation of a resource that park users can reach. The research also provides a comprehensive evaluation to understand the park usage habits and motivations of teenagers, and in this context, it has contributed to the development of recommendations for the design and management of parks. Thus, the importance of park features that allow teenagers to lead a more active life and increase their social interactions is emphasized.

This research was conducted in 2020 to determine the effects of leonardite-derived humic acids (Humas-15, Liquid Humus and Humico Maximix-K) with different properties, along with reduced nitrogen fertilization, on tuber yield and quality in potatoes (cv. Van Gogh). In the study, chemical fertilizer applications were made as basic fertilization (20 N 10 P 10 K), reduced fertilization I (15 N 10 P 10 K) and reduced fertilization II (10 N 10 P 10 K). Humic acids were applied twice with irrigation water, at the beginning of the flowering period and 15 days later. Humas-15 and Liquid Humus were applied at 1.0 and 2.0 lt/da doses, and Humico Maximix-K was applied at 400 and 800 g/da doses. A total of seven traits (tuber number per plant, tuber yield per plant, marketable tuber yield, total tuber yield, dry matter content, reducing sugar content and total sugar content) were measured. Reducing nitrogen applications with humic acid applications significantly affected all the traits studied. Humic acid applications combined with reduced nitrogen fertilization increased the number of tubers per plant by up to 13%, marketable tuber yield by up to 18% and total tuber yield by up to 16% compared with the control. Total and reducing sugar contents varied between 1.27-1.58% and 159-389 mg/100g fw, respectively depending on the applications. In the study, the highest tuber yield was obtained from 1.0 and 2.0 L/da Humas-15 and 2.0 L/da Liquid Humus applications applied together with reducing nitrogen applications which have close values to the recommended fertilization applications.

This study was carried out to determine the effects of some tillage methods; it included conventional tillage and conservation tillage with some weed control applications on weed manifestation in organic vineyards. The organic vineyard experiment area was designed as main and sub-plots. The effects of some methods of conventional tillage, no-tillage, and conservation tillage on weed coverage, densities, fresh weight, and dry weight were determined in the organic vineyard experiment area. These tillage methods were applied in the main plots. A chisel and heavy-duty disk harrow were used for conservation tillage methods. The plough and disc harrow were also applied as conventional methods. Other allelopathic methods (olive mill wastewater, radish (Raphanus sativus L.), and broccoli (Brassica oleracea L.) were applied as sub-plots in the experiment area. As a result of the statistical analysis of the values obtained in the study, the most effective method, the application of the plough and disc harrow, was determined for weed coverage and fresh and dry weight weeds in the main plots. The olive mill wastewater was also determined as the most effective application in the sub-plots. In terms of grape yield, the most effective method in the main plots was the plough + disc harrow application (6.8068 kg vinestock‒1). The planting of broccoli (6.4485 kg vinestock‒1) was determined as the most effective sub-plot application for grape yield.

Fatih Şevki Erkuş | Koray Tuncay
Cattle manure (CM) is mostly used as an inoculum in order to start-up of agricultural biogas plants or as a co-substrate in the anaerobic digestion of lignocellulosic content. Rumen fluid microbiota is also considered to be effective in lignocellulose digestion. It is known that microorganisms in the ruminal waste facilitate the hydrolysis of lignocellulosic structures. However, there are few studies on the inoculum effect of rumen microorganisms on bioreactor performances when rumen content is used as co-substrate and inoculum together with cattle manure, and it is not clear how rumen waste can be used in various anaerobic digestion systems. In this study, biogas production efficiencies obtained from lignocellulosic content in mono and cosubstrate (1:1 and 1:2 Volatile Solids) bioreactors formed by using ruminal waste (RW) and CM microbial communities were investigated. In order to determine the biogas production efficiencies, biomethane potential (BMP) experiments that simulate anaerobic digestion process conditions in a laboratory environment were applied. Treatment with 50% application of RW cosubstrate, 65.51% biogas and 70.64% methane production efficiency increases were achieved compared to monosubstrate CM bioreactor.

There is an increasing trend for development of alternatives to deliver probiotics with non-dairy products. Fruit juices have become one of main food products for delivery of probiotics. The availability of different fruit juice types, their fresh and healthy perception from the consumer's side and demand for plant-based products increase attention to fortification of fruit juices with probiotics. Yet, development of probiotic fruit juices is still an emerging area for the functional food concept. Probiotic juices can be developed by using both probiotic Lactobacillus and Bifidobacterium and their viability can be strain specific as well dependent on the utilized fruits. The transformation of the fruit components can play roles for the improvement of the potential health promoting functions of fruit juices which should be well-characterized. The insufficient viability of probiotic strains during shelf-life of fruit juices is one of the main challenges and efficient and relatively cheap encapsulation techniques should be developed to ensure their viability. In this study, recent achievements and developments to produce probiotic fruit juices have been summarized. Also, potential role of probiotic fortification for the health promoting functions of fruit juices related to probiotic metabolism has been discussed. Finally, strategies to increase the viability of distinct probiotics have been discussed.

Kombucha is a slightly acidic sugary drink made by fermenting sweetened tea. It is known for its numerous health advantages. The objective of this study is to explore the possible effects of Salvia officinalis on enhancing the biochemical characteristics of kombucha. The present investigation compared traditional kombucha, produced using green and black tea, with kombucha derived from S. officinalis, examining their antioxidant properties, total phenolic, and total flavonoid content. The fermentation process lasted for a duration of 14 days. The present study was performed to evaluate the antioxidant activity of fermented S. officinalis. The antioxidant potential was assessed using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity and copper (II) reducing antioxidant capacity (CUPRAC) techniques. The DPPH radical reduction percentages were determined to be 93.5±1.65% for kombucha of green tea, 90.6±1.51% for kombucha of black tea, and 88.5±1.68% for kombucha of S. officinalis. According to the CUPRAC results, green tea kombucha was found to have 321.58±2.12 mg TE/g, black tea kombucha 305.91±1.98 mg TE/g and S. officinalis kombucha 301.97±1.78 mg TE/g. Total phenolic content was 154.15±1.22 mg GAE/g for kombucha of green tea, 145.41±1.31 mg GAE/g for kombucha of black tea, and 124.52±1.25 mg GAE/g for kombucha of S. officinalis. The determined value for the total flavonoid content was 101.12±0.98 mg QE/g for kombucha of green tea, 99.41±0.97 mg QE/g for kombucha of black tea, and 92.73±0.78 mg QE/g for kombucha of S. officinalis. The findings indicate that S. officinalis can serve as a substitute medium for kombucha fermentation, resulting in the development of a novel kind of kombucha with similar chemical characteristics.
