In this study, it was aimed to determine some physiological effects of CuO nanoparticle on C. demersum. The plants were collected from an uncontaminated pond in Gaziantep province. Different concentrations of CuO (0, 25, 50, 100 and 200 mg/L) were applied to the macrophytes after being acclimatized in controlled conditions. Some analyses were made on macrophytes harvested at the end of the application. The contents of protein, total carbohydrate, photosynthetic pigment, total phenolic compound, non-protein sulfhydryl groups of tissues increased with increasing CuO concentration under the influence of applied CuO concentrations. In addition, increases in hydrogen peroxide and MDA contents were also detected. As a result, it was determined that the applied CuO concentrations caused some physiological changes in C. demersum tissues.

In this study, the project studio, which is the foundation of interior design education, has been designed using the metaphor method, one of the intellectual methods applied in education. The metaphor method is a technique used to make difficult-to-understand abstract concepts concrete and helps design students develop their critical thinking and creative skills. In this case, design, which is the verbalized form of abstract thought, is limited to an object and the responsibilities brought by this object. From this point of view, an experimental study of metaphorical methods for establishing spatial relations of objects was carried out in a 14-week design studio with the 2nd year students of the Department of Interior Architecture, Faculty of Architecture and Design, Selcuk University. The purpose of the studio work is to draw the boundaries of interior architecture students in their search for solutions to design problems, and to enable them to come up with creative designs while making functional and formal decisions. In this context, a metaphorical approach was used in the context of object-space relations to guide students’ formal decisions in the functional solutions of the problems that arise in the interior design process. After working in the studio, the students have developed a working doctrine that will guide their interior design studio projects using the designed method, allow them to create unique forms and shapes, enable them to translate abstract ideas into concrete space and make it possible for them to design at various scales, from equipment to space design. The method is at a level that will set an example for students, designers and academicians working in the design discipline.

A comparative study between natural and synthetic environments is carried out by realizing six fermentation experiments in batch culture. The objective of this study is to consider the effect of carbon sources on growth and the production of glutamic acid by Corynebacterium glutamicum 2262. The difference between the culture media lies in the carbon source. Two natural environments of date juice, one of which is treated with invertase to hydrolyse sucrose with a concentration of total sugars of 88 g/L. Four synthetic media with a concentration of 34 g/L sugars: medium containing mixed sugars (glucose + fructose + sucrose) with rates proportional to that of date juice, the other three media are composed of a single sugar (either glucose, fructose, or sucrose). The results showed that Corynebacterium glutamicum is able to use the three sugars whether they are single or mixed, although the best results of glutamate production (8.41 g/L) are obtained on the mixture of three sugars, which explains the interest and valorisation of date waste. On the other hand, the date juice-based media are shown to have a glutamate concentration of 7.98 g/L during the hydrolysis of sucrose of date juice.

In the study; fruit skin color parameters, fruit flesh firmness and total soluable solid (TSS) ratios, as well as total acidity, total phenolic substance, total monomeric anth°Cyanin amounts and total antioxidant capacity were determined. After the fruits were harvested, they were immersed in three different doses (0-2-4%) of calcium chloride (CaCl2) solution for 5 minutes. The fruits removed from the solution were kept to dry. The fruits were stored for 14 days in a cold store with a temperature of 1-2°C and a relative humidity of 90±5%. Before the storage and on the 7th and 14th days of storage, the fruits samples were taken and kept on the shelves in the rooms with a temperature of 21±1°C and a relative humidity of 60±5%for 3 days. Measurements and analyses of fruit quality parameters were made in the samples taken from the fruits that were kept on the shelf for three days. As a result of the study, it was determined that 4%CaCl2 application was effective in maintaining fruit flesh firmness. In fruits kept on the shelf for 3 days after 14 days of storage, SSC of 4%CaCl2 treatment was found to be higher than the control treatment. Compared to the control, 4%CaCl2 caused a significant increase in the total phenol content. The highest total monomeric anth°Cyanin content and total antioxidant capacity was determined in the control treatment. While there were no significant changes in L* values between treatments, a* and b* values were found to be higher in 2%CaCl2 treatment. In the light of the data obtained, it was concluded that 4%CaCl2 application had a positive effect on the shelf life of strawberry fruits.

This study was carried out to determine the effects of plant growth-promoting rhizobacteria and mycorrhiza treatments on the development of Zinnia elegans L. ‘Zesty’ and Dahlia variabilis L. ‘Figaro Violet’ cultivars. In the study, a suspension was first prepared from bacterial isolates developed at 25±2 °C for 24 hours. The prepared suspensions were adjusted to an absorbance value of 0,3 at 600 nanometers in a spectrophotometer. D. variabilis seedlings were immersed in suspensions prepared from ZE-12, ZE-13 and ZE-12+ZE-13, Z. elegans seedlings were immersed in suspensions prepared from ZE-2, ZE-7, ZE-12, ZE-13, ZE-12+ZE-13 for 30 minutes. In addition, Z. elegans seedlings were kept in mycorrhiza prepared at a concentration of 5000 ppm for 10 seconds. At the end of the period, flower seedlings were planted in pots with a mixture of peat and perlite. As the control group, seedlings without rhizobacteria and mycorrhiza treatment were used in both cultivars. The experiment was established with 3 replications and 10 plants per replication. The applications made in the D. variabilis experiment remained the same as the control in all other parameters except root dry weight. ZE-13 application was effective on root dry weight. It was determined that the applications made in Z. elegans seedlings increased the flower stem thickness and the number of leaves, especially the ZE-13 application was the most effective application. In conclusion, with this study, it was revealed that rhizobacteria and mycorrhiza applications, which are of natural origin and do not harm the environment, have the potential to be used in ornamental plants cultivation, and that these applications should be expanded.

Trees in upland, semiarid agroecological zones typically require water efficiency due to low rainfall, cold and dry temperatures as in Niğde Province, Central Anatolia, Türkiye. This study quantitatively assessed farmer perception of ecosystem services and production advantage of trees in a semiarid zone. Forty-nine farmers in Niğde Province were surveyed. The survey evaluated two major factors: ecosystem services and production advantage using eleven indicators. The responses were grouped by age, gender, education, district class (rural and urban) and farm settlement (rural and urban) and were analysed by test of association (χ2) at P≤0.05. Most farmers had knowledge of trees in their environment and mainly supported the perspective that trees were important mainly for cultural and provisioning ecosystem services. However, they held the opinion that having trees on their farmer was a production disadvantage in a semiarid agroecological zone. Although there were no gender differences in their perspectives, there were significant difference by age, education, district class and farm settlement. Farmers in this semiarid agroecological zone seemed more interested in trees with evident ecosystem services and production advantage such as improved crop yield, water efficiency, weed and pest management, ease of harvesting as well as reduced overall production cost. By implication, trees with multiple benefits are required if further planting by farmers is to be encouraged for agroecosystem improvement. In addition, tree choice will be based on farmer perception of the benefits of trees for ecosystem services and production advantage and further research to identify and promote trees that benefits the widest range of agroecosystems.

This is study is based with the support of RS-GIS technology on the land use of Samsun Center, as well as the coastal districts of Ilkadım,Atakum,Bafra Plain, through the processing and interpretation of satellite images in the summer months of 2000,2010,2020. Spatial and temporal variability properties of LU/LC were determined using MLC algorithm, controlled classification approach. The predictive values of the LU/LC change that will occur in 2030, calculated with the MLP‑ANN model based on Machine Learning algorithms and mapped with the QGIS 3.16 program. To determine the accuracy coefficient of the model, 2020 LU/LC simulation performed using the transition potential matrix of 2000 and 2010 LU/LC data. The results of simulation were compared the data of land use land cover with the 2020 to evaluate the accuracy of the simulation model. The model of MLP‑ANN provided an accuracy of 72% based on the kappa fit index. According to MLP‑ANN model 2030 results were an increase of 73.33 km² in built up areas, an increase of 56.89 km² in bare areas, and a decrease of 129.66 km² in green areas. It provided a reference basis for future Samsun urban to rural coastline LU planning and management and LU structure optimization.

In this study, the effect of P. arvense-H. vulgare mixture and V. pannonica grown in the fallow year on silage yield and quality of subsequent cereals were investigated in the arid condition of Eskişehir, Turkey. The fresh weight of P. arvense-H. vulgare mixture with 2750 kg/da was found two-fold high than V. pannonica. P. arvense-H. vulgare mixture significantly increased the fresh and dry hay weights of cereals except for H. vulgare cv. İnce. In addition, the highest grain yield was obtained by growing Triticosecale cv. Karma in P. arvense-H. vulgare mixture plots. Due to the high pH and low dry matter content of triticale samples, the Fleig scores were very low, which is a quality indicator in silage. ADF and NDF ratios were the highest in A. sativa cv. Checato as a negative quality factor. Top-dressing of nitrogen had a positive effect on the crude protein ratio. It was concluded that production of quality roughage can be sustainably increased by growing P. arvense-H. vulgare mixture in barren areas in the fallow year and followed by sowed cvs. Karma, Müfitbey, and Checato in the cereal growing season.

To enhance wheat yield, adoption and management practices have become a major concern of agricultural extension activities and low produce of wheat is partly due to poor agronomic practices in Ethiopia. Compared to broadcasting system, row planting gives better yield with quality of the seed at harvesting period. The study was conducted to assess the opportunities and status of wheat row planting by farmers. This study was used descriptive research design and employed both quantitative and qualitative approaches. Primary data were collected from 141_sample households which were selected randomly. Additional information was obtained from focus group discussion and key informant interview. The data has been analyzed by using simple descriptive statistics such as mean, percentage and standard deviation. Moreover, inferential statistics like chi-square and t-test were used. The result shows that, education level, family size, farmers experience, seeding rate per hectare, yield per hectare, fertilizer rate per hectare and income of household were positive association with wheat row planting in the study area. Also, non-adopter farmers was not use the existing opportunity such as off-farm income generating activities, contact with extension agents, credit use, membership in cooperatives and improved seed in the study area. Moreover, more than half of smallholders not adopt the wheat row planting system; meaning, still they use broadcasting system of Planting in their farms. Therefore, the study concludes that, Policies and strategies that focus on farmers’ education, implementation of well-established extension package are helpful so as to achieve wider adoption of row planting technology of smallholder farmer in the study area.

40 samples of tahini halva from 5 different firms, in 4 distinct varieties—plain, hazelnut, carob, and vanilla—were gathered for this study from producers in the provinces of Balikesir and Bursa as well as from commercial markets. Samples were taken from two different lot numbers for each company. As a result of the analyzes made on the tahini halva samples, it was determined that the total amount of sesame oil varied between 24.67-38.87%, the total amount of tahini ranged between 59.34-69.7%, the total moisture amount was between 0.1-0.9%, the total ash amount was 0.089-3.16%, and the total salt amount was between 0.001-0.024%; as a result of microbiological cultivations in which the presence of yeast and mold were analyzed, an average of 10 cfu/g in plain tahini halva samples, an average of 90 cfu/g in hazelnut tahini halva samples, an average of 45 cfu/g in carob tahini halva samples, and an average of 25 cfu/g in vanilla tahini halva samples were determined. All samples of tahini halva were found to be free of contamination with Salmonella spp., Staphylococcus aureus or Escherichia coli. When all of these findings were taken into consideration, it was found that one of the sampled firms did not produce in accordance with the Turkish Food Codex Communique on Tahini Halva (2015/28) in terms of total sesame oil (%) and ash content (%) of two companies. Combined, the findings of the chemical and microbiological analyses indicate that 85% of the samples were prepared in line with the TFC.
