For Turkish society, bread has been an indispensable part of the kitchen and daily life throughout history. Due to its high consumption in Turkish society, it plays an important role in terms of both health and nutritional habits. Contamination from the soil where wheat is planted to the bread making process is of great importance for health. In this study, the amounts of heavy metals such as aluminum, copper, nickel, chromium, manganese, iron, lead and cadmium in the soil of an agricultural land, in flour obtained from wheat grown there and in bread made from this flour were investigated using ICP-MS. The average levels of Al, Cr, Cu, Mn, Ni, Cd, Fe, Pb and As in soil samples were 120.46, 12.23, 44.9, 93.46, 10.83, 2.06, 196.87, 1.96 and 0.21 mg/kg, respectively. In flour samples, these levels were 17.20, 2.03, 28.93, 26.3, 3.37, 0.09, 30.93, 1.37 and 0.03 mg/kg, respectively. In bread samples, 11.27, 0.77, 8.27, 18.63, 0.4, 0.02, 12.76, 0.04 and 0.001 mg/kg, respectively. The results obtained show that high metal levels in the soil are also found in bread. This indicates that heavy metal levels in bread may pose health risks in long-term consumption. Especially levels of aluminum, nickel, chromium and cadmium metals can cause serious health problems. Therefore, it is important to reduce heavy metal contamination in agriculture and production processes and to conduct regular inspections. Compliance with maximum limits set by health authorities and regulatory agencies is also critical for public health.

This study investigated the effects of Potato Golden Cyst Nematode (Globodera rostochiensis) on plant development and tuber yield in naturally infested fields with and without nematicides. The study was arranged in a randomized block design in the Alay district of Niğde province in 2021. In the study 4 varieties (PAE 13-08-07 clone, Ünlenen, Leventbey, Muratbey) developed by Niğde Potato Research Institute and two controls (Desiree and Bettina) were used. 50% emergence time, 50% flowering time, number of stems per plant, plant height, tuber maturation time, number of large tubers in total tuber and tuber yield per hectare were examined in potato varieties. No difference was detected in 50% emergence time, number of stems per plant and 50% flowering time in potato varieties in the nematicide-applied area and the nematode-infested area. Varieties were affected by nematicide application at varying rates in terms of plant height and tuber maturation time. The most significant increase in tuber size and tuber weight was observed as a result of nematicide application in the field infested with Potato Golden Cyst nematode.

Parks and public open green spaces are open spaces for all segments of the society. These places, which are important recreation areas, enable the elderly to renew themselves, to breathe a little in the open air, to be alone with nature even in the city. These opportunities provided by parks are utilised by elderly users. Today, the population of elderly individuals is increasing day by day due to the slowdown in population growth rate. In this study, it is aimed to determine the park usage purposes of the elderly and important park features that encourage physical activity and social interaction. Within the scope of the research, 96 elderly individuals were interviewed with 96 elderly individuals within the scope of face-to-face survey study by going to the park at random times on weekdays and weekends on a voluntary basis by using the questionnaire form prepared for revealing the user profile of individuals aged 40 and over in Ihlamur Park in Selçuklu District, determining the preference times of the park, determining the duration and times of park use, determining the reasons for park preference and selection, and evaluating park user satisfaction and expectations. The findings show that parks are an important social area for elderly people in the same age group with their seating areas, walking paths, simple fitness equipment, as they create a gathering area for elderly people in the same age group, and therefore, parks require careful planning and implementation in the design, management and use of parks and should contain a large amount of space for socialization. In line with these findings, it will be possible for elderly people to benefit more from parks and have a more enjoyable time with landscape designs that provide socialization opportunities for elderly users. Thus, elderly individuals will be able to develop a sense of belonging for the park.

Honeydew is a sugar-rich, sticky substance secreted by many plant-feeding insect species from the order of Hemiptera and Lepidoptera. Aphids (Hemiptera: Aphididae), on the other hand, feed on nitrogen-poor, carbohydrate-rich phloem sap and excrete excess carbohydrate as honeydew from their anus. The aphids, constituting the main material of the study were sampled from the Catalpa bungei C. A. Mey (Bignoniaceae) tree located in the central campus of Niğde Ömer Halisdemir University and then preparation procedures were carried out for species identification under laboratory conditions. According to the identification key organized according to the host plant, the samples were identified as Aphis gossypii Glover. The honeydew of A. gossypii Glover, known as the cotton aphid, was collected from the host plant and the effects of two different concentrations of the honeydew (10 and 20 g/L) on fungal growth were determined using both solid and liquid media. Different Trichoderma strains and Beauveria bassiana were used to examine fungal growth. Fungal growth in the prepared nutrient media was determined as the amount of biomass (gram). The honeydew content (phenolic substance, sugar and amino acid amounts) was determined and supported by FT-IR analyses. The growth of fungal species in the PDA medium, which was preferred as the control medium, and the medium containing honeydew was compared. It has been determined that fungal growth is better in the medium containing honeydew, and therefore honeydew increases fungal growth. With this study, it is predicted that aphid honeydew can support the growth of both fungal agents used in biological control and plant pathogens.

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 under controlled conditions to determine the effects of chitosan-based nanoemulsion film coating formulations, formed using different essential oils, on storage quality of sugar beet roots during storage period. In the study, roots of Conviso Smart (KWS) sugar beet variety were coated with nanoemulsion film formulations containing thyme (Thymus vulgaris), clove (Szygium aromaticum), ginger (Zingiber officinale) and tea tree (Melaleuca alternifolia) essential oils doses of 250, 500 and 1000 ppm immediately after harvest. The roots were stored in plastic cases under controlled conditions (+ 8-10°C, 85-90% relative humidity) for 90 days. Weight loss in beet roots was determined at 30-day intervals from the start of the storage period, and at the end of the storage period, firmness, dry matter ratio, brix value, polar sugar, reducing sugar, alpha amino nitrogen and glycine betaine contents and fungal infection developments in beet roots were also evaluated. The film coating applications significantly affected postharvest weight and quality losses in sugar beet roots. The applications significantly reduced roots weight loss during storage compared to the control. Although the polar sugar ratios were higher in film coated roots compared to the control, alpha-amino nitrogen, glycine betaine, and reducing sugar contents showed significant decreases. White mold and green mold infections on the roots were significantly decreased, especially with high dose film coating applications. The highest dry matter ratio, brix values and firmness were obtained from film coatings containing 1000 ppm cinnamon and thyme essential oils. While polar sugar ratio was higher in root which film coated compared to the control, alpha amino nitrogen, glycine betaine and reducing sugar contents showed significant decreases. White mold and green mold infections developing on root showed significant decreases especially with film coating applications applied at high doses. The study concluded that coating sugar beet roots with nanoemulsion film formulations containing essential oils can significantly reduce, weight and quality losses, as well as fungal disease development, during the storage period.
