The aim of this study was to investigate the effects of the treatment of tap water (control), sodium hypochlorite (SH), electrolyzed oxidizing water (EOW), and hydrogen peroxide (HP) on the color, texture, and sensory properties of the Eruca vesicaria as a quality criterion. For this purpose, three different concentrations (25, 50, and 75 ppm) and three different times (1, 3, and 5 min) were applied in all three washing processes. There weren’t statistically significant differences in objective (color and texture) and subjective (sensory) results in all three washing processes in terms of both concentration and time. Thus, it was determined that these processes did not have a negative effect on the quality of green leafy vegetables.

Bread is the basic nutrient that human beings have consumed for centuries. This is because it is affordable, nutritious and satisfying. The most consumed bread on a daily basis is white bread made from refined flours. Since white breads are made from flour that has been separated from the bran and germ, they are poor in other nutrients (dietary fiber, phenolic compounds and minor nutrients) with a high starch content. For this reason, studies on increasing the nutritional value and functionalization of white bread have attracted attention for years. In this study, the changes in physical, chemical, sensory and textural properties of bread were evaluated with the addition of purple cabbage, sorrel, capia pepper, pomegranate, pumpkin and cherry extracts to bread production. It was determined that the bread was enriched with phenolics with the addition of extracts (65% on flour basis) and the best sensory results were the breads with the addition of capia pepper extract.

Economic growth and employment are taken as the two major objectives of macroeconomic policy schema in both the developing as well as developed countries. This study aims to determine the relationship between the unemployment rate and GDP growth rate of Nepal using the time-series data from 1991-2020. Difference version approach, dynamic version approach and Granger causality test were used to study the relationship between the macroeconomic variables. The difference version and dynamic version approach showed non-significant results for the regression of unemployment rate on economic growth rate which implies that the unemployment rate is not significantly affected by the economic growth rate of Nepal. The Okun’s coefficient in the difference version was -0.057 and in the dynamic version approach it was -0.058. Thus, the Okun’s law doesn’t seem to hold in case of Nepal’s economy. The Granger causality test also revealed that the change in the unemployment rate is not a predictive variable of the GDP growth rate and vice versa. The non-significant relationship between the macroeconomic variables might thus be affected by other factors. Thus, it can be suggested to the government and policymakers to recuperate the ways of solving the unemployment by formulating economic policies that are more directed towards structural and labor market transformation. Tax reduction policy, increase in government spending, skill enhancement programs and youth employment subsidy can also be suggested.

This study was conducted to determine the fertility potential of the agricultural soils of Ağrı/Eleşkirt region and the levels of basic plant nutrients. Texture classes of soil samples of the research area was; loam, clay loam and sandy clay timbre, 55% loam, 40% clay timbre and 5% sandy clay. The pH of the soils varies between 6.50-7.57, with an average of 7.14 neutral and CEC values between 17.3-29.5 cmol/kg. Lime content is 3.95-12.10%, mean of 7.11%; 30% are limy and 70% are medium limy, organic matter contents are 1.20-2.59%, average of 2%, 45% organic matter is considered low and 55% is medium. Their EC was between 0.14 and 0.43 dS/m, with an average of 0.21 dS/m; there is no salinity problem in the soils. Total N contents were 0.03-0.10%; 15% is very little, 65% is insufficient and 20% is sufficient, plant-friendly P, between 5.67-11.7 mg/kg; 20% is insufficient and 80% is sufficient; K content was 1.09-1.77 cmol/kg, an average of 1.45 cmol/kg is sufficient and excessive. The interchangeable Ca 7.90-9.90 cmol/kg is sufficient, with an average of 8.82 cmol/kg. Changeable Na, 0.87-1.56 cmol/kg, average 1.20 cmol/kg, normal level; plant Fe is sufficient in 12 of the 2.78 mg/kg to 6.90 mg/kg, 60% of the soils are sufficient and 40% are insufficient; Cu, available zinc (Zn) contents 0.29 to 0.78 mg/kg; 10% are sufficient and 90% have insufficient available Zn content; the available Mn level was insufficient in all soil samples. As a result, it was determined that at least half of the research area soils are in dire need of increasing the organic matter content, nitrogen fertilizer, partially phosphorus fertilizer and especially microelement fertilizers such as Zn and Mn. Therefore, it is recommended to eliminate the deficiencies with macro and micro elements in leaf or organo-mineral (micro-element-containing) fertilizers in light of economic and ecological planning by conducting correlation and calibration studies with plant response.

This study was carried out in order to determine the effects of dill, clove and hyssop essential oils and fungicides applied on sugar beet roots on beet storage quality during the storage period. The roots of Esperanza (KWS) variety, which was produced in the experimental areas in 2019, were used in the study. Roots were treated with 100, 500 and 1000 ppm doses of dill (Anethum graveolens L.), clove (Szygium aromaticum) and hyssop (Echinophora tenuifolia) essential oils, synthetic fungicide (80% Thiram) and Tween-80 right after harvest and the roots were placed in the storage. Weight loss of roots determined at 15-day intervals from the beginning of the storage period, dry matter ratio, brix, polar sugar, reducing sugar and alpha amino nitrogen contents, phytotoxicity and fungal infection development at the end of the 3-month storage period. The applications made in the research significantly affected the post-harvest weight and quality losses in beet. Depending on the applications, the weight losses at the end of the 3-month storage period varied between 9.43-19.90%, and the weight losses in essential oil applications were lower than the control. The highest dry matter content and brix values were obtained from clove essential oil and fungicide and Tween-80 applications. While Tween-80 and fungicide applications increased the polar sugar content compared to the control, 1000 ppm clove essential oil caused a significant decrease in the polar sugar content. In the study, reducing sugar and alpha amino nitrogen contents of roots applied 1000 ppm essential oil E. tenuifolia essential oil were lower. E. tenuifolia essential oil showed the highest antifungal activity against white mold and green mold infections. It was concluded that with the application of essential oil to the roots after the harvest, both weight and quality losses and the development of fungal diseases can be reduced, however, some active substances may cause phytotoxicity in the roots.

In this study, it was aimed to increase grain yield and grain zinc content by foliar application of zinc in different soybean varieties. In this study, umut-2002, altınay and cinsoy cultivars were used as material and foliar zinc application (0-60 kg ha-1) was applied to these cultivars. In the study, plant height, first pod height, leaf chlorophyll content, number of pods per plant, number of pods per pod, 100-seed weight, grain yield, grain protein content and grain zinc ratio were measured. This increase was also observed in grain protein content and grain zinc content. Among the varieties, the highest grain yield was obtained from the Umut-2002 variety, while the highest protein content was measured from the Altıny variety.

High concentrations of chromium in the soil have a toxic effect on the living organisms in the soil ecosystem. If chromium, which is not an absolute essential element, accumulates in plants, it causes structural changes, causing a decrease in plant growth and also high toxicity due to its accumulation in biomass. Use of plants to remove chromium (Cr) from contaminated soils, it is an environmentally efficient, cost-effective, modern, applicable technique. The different species of plant and ornamental plants are used in this technique. In this study, the Kordes shrub rose used in landscaping in our province, Cr phytoremediation capacity was evaluated by growing at contaminated soil with Cr. In the study, the different doses of Cr (0, 50, 100, 500, 1000 mg kg-1) have been applied in Cr+3 and Cr+6 forms. In addition, two doses (0% and 3%) of leonardite were added to the pots to determine the effect on the developmental status of the plants and Cr uptake. In the study, plant height, number of branches, number of flowers, flower diameter, stem diameter, flower yield values and total wet and dry weight values at the end of the experiment were determined. At the end of the experiment, it was observed that generally developmental status of the plants was adversely affected at high Cr doses. Especially at 500 and 1000 mg kg-1 application doses was observed that the plants could not withstand Cr toxicity in a short time. It has been observed that plants treated with leonardite were healthier than those without. According to the data obtained at the end of the study, it was determined that the resistance of plant to high doses of Cr was low, but it showed better growth at 50 and 100 mg kg-1 doses.

This study aimed to analyze the spatial perception of educational buildings with historical significance by users. In this context, Antalya Vocational and Technical Anatolian High School, which is a historical building, was discussed as a material. A questionnaire was applied to individuals who graduated from this high school to examine how the facade design and garden layout were perceived in the spatial evaluation of the high school discussed in the study. Three different facade designs (modern, traditional, and mixed) based on the building complex were prepared using the AutoCAD, 3D Max, and Photoshop CS3 programs to be used in the questionnaire form consisting of open-ended and closed-ended questions. The frequency analysis was performed using the SPSS program to evaluate the data obtained after the questionnaire. According to the obtained results, it was determined that the middle age group was highly interested in the traditional and mixed facade design. It was observed that the participants further preferred the modern facade design as their level of education increased. It was observed that the participants preferred the mixed facade design more as their income level increased. Furthermore, it was determined that the mixed facade design was generally preferred more by the participants. In conclusion, the quality of historical buildings from the past should be updated with a modern perspective. Thus, positive effects will be achieved for the continuity of the building and its compliance with the environment. It is foreseen to provide positive effects both in terms of functionality and in the field of visual admiration and comfort by evaluating the changing needs of society over time and environmental factors together. On the other hand, while positive elements ensure the continuity of buildings and building complexes, it will also be possible to contribute to their becoming an urban image.

Ethiopia is considered as the possible origin and center of diversity for okra. Therefore, this study was conducted with the objectives of determining the genetic distance between indigenous okra collections and exotic commercial varieties and assessing genetic diversity of okra genotypes. The field experiment was conducted at Dire Dawa in 2016 using 14 indigenous collections and 11 exotic varieties in 5 x 5 triple lattice design. Data were collected on 9 and 29 qualitative and quantitative traits, respectively. The genetic distance measured by Euclidean distance ranged from 3.1 to 12.6 with a mean of 7.2. The highest genetic distances were observed between indigenous okra collections and exotic varieties viz. Guba-12 and NamdHari (12.6) followed by Guba-12 and Vellayani (12.3) and Mythri and Guba-12 (11.8). Dendrogram constructed by Unweighted Pair-group Method with Arithmetic Means grouped the 25 genotypes into seven major clusters in which the three clusters (Cluster II, III and V) were solitary, consisted of one genotype each, Cluster I consisted of six Indian commercial varieties, Cluster IV comprised of seven genotypes (four indigenous okra collections, one variety from USA and two from India), while Cluster VI and VII comprised of 5 and 4 indigenous okra collections, respectively. This study revealed the presence of wide genetic diversity among indigenous okra collections and exotic commercial varieties.

Grape pickle is a traditional food that is made with grapes (Vitis vinifera), horseradish (Armoracia rusticana) and grape syrup. In this study, the survival of Bacillus cereus and Escherichia coli in grape pickles produced with or without using probiotic Lactobacillus acidophilus La-5 as well as microbiological, chemical and sensory properties of each group were examined during 35 days of ripening at 25°C and 5 months at refrigerated storage period. Molds and lactic acid bacteria (LAB) counts remained below the limit of detection (6 log in samples to be considered a probiotic product. E. coli counts rapidly declined to undetectable level within 7 days, while B. cereus numbers was found 1.56-1.72 log cfu/g at the end of the storage period. As a result, it was established that traditional grape pickle is not suitable food matrix for probiotication. High total soluble solid content (63 °Brix) and presence of horseradish in grape pickles ensure the microbiological stability as well as the safety of product.
