Orhun Soydan
The subject of the study is to evaluate the Niğde Akkaya Dam with SWOT analysis and to make recommendations in terms of recreational use. The aim of the study is to identify the strengths and weaknesses, threats and opportunities of the Akkaya dam and to determine its goals and strategies in terms of recreation. In line with this purpose, the socio-economic, cultural and natural features, landscape potential of the area were evaluated using the SWOT, the opportunities that the positive and negative aspects of the area, were presented, and the possible or existing threats were determined. At the same time, the current recreation potential of the dam was determined, and suggestions were developed in line with the data in order to offer alternatives that can be evaluated in terms of sustainable use of the areas. It was determined that pollution occurs in the dam water due to environmental wastes, as a result of this pollution, harmful creatures multiply and bad smells are formed. However, it is accepted that the dam is home to a large number of migratory birds, that it has not lost its naturalness, and that most of the dam is in the university campus. Threats to the dam are; low water level, fishing, duck hunting etc. damage to ecological life due to activities, smell gradually increased. Their opportunities are determined as providing a suitable environment for bird watching, having a suitable infrastructure for ecological research, and being suitable for recreational activities for water. At the end of the study, suggestions were developed in terms of suitability of Akkaya Dam for recreational activities.

Tasisa Temesgen Tolossa
The increasing scarcity and competition for irrigation water entails adoption of innovativepractices that increase efficient water use. The objective of this research was to compare different mulching techniques and investigated the combined effect of irrigation levels under drip irrigation system based on the parametric evaluation system in western part of Ethiopia during the 2018 dry season. A factorial combination of five levels of water (namely 100%, 80% and 70%, 60% and 50%ETc) combined with three mulch treatments (namely, Normal Mulch (NM), Straw Mulch (SM) and Plastic Mulch (PM)) with three replications. The analysis of variance showed that, days to 50% maturity, leaf number per plant, mean leaf length, plant height and leaf area were significantly affected by the main effects of deficit irrigation levels and mulching materials. The interaction effects of deficit irrigation levels and mulching materials significantly influenced plant height, number of leaf per plant, plant height, Leaf length and Leaf area of the onion. The present study suggests that, in water scarce area, farmers are advised to adopt deficit irrigation level with 80% ETc under plastic mulch. It is important even to undertake similar studies at different seasons with different varieties in consideration of their cost benefit analysis. However, if water is not a limiting factor, farmers are advised to apply full irrigation water application under plastic mulch.

This study was conducted in two locations have different altitudes in the cities which have different climates as Ankara, Ordu, Erzurum, Mersin. The purpose of this work was to define some physiological properties of the bees such as the survivability of colony, wintering ability, usage of stoked honey and to discuss all these data. This study lasted two years and the second year was the continuation of the first year. At the beginning of the year, colonies which has the same genotype were equalized as number of combs covered with bees, stocked honey and brood areas and so on. According to the data analysis, it was obtained that the quantity of the stocked honey was not statistically significant by the region×altitude×year interaction. However, year×region and region×altitude interactions were statistically significant. Similarly, it was obtained that the wintering ability was not statistically significant by the region×altitude×year interaction. The only year×region interaction was statistically significant. Also, descriptive statistics obtained for the survivability of the colonies (%) during the first and second year was added statistically to this application. As a result, this work showed that migratory beekeepers could reevaluate the regions which have the microclimate properties in Aegean, Mediterranean, and the Black Sea. And new research should be made by adding different species of honeybees for the performance of overwintering in different climates.

Aydın Alp | Özlem Toncer | Sadettin Çelik
Tobaccos produced in Turkey are grouped under different names according to the different environmental properties and various characteristics of the regions where they were grown. Lice tobacco is an important local tobacco variety cultivated under Lice-Hazro and Kulp districts conditions. In recent years, a large number of tobacco origin and village populations disappeared from production and faced the danger of extinction. Especially the Lice local tobacco variety has gained a very good adaptation ability against the stress factors of the region. Different environmental factors such as high altitude, stony areas and high temperature, low rainfall and low nitrogen soils have determined the important quality characteristics that distinguish Lice tobacco from other tobacco types. The short plant height and reverse conical plant shape in Lice Tobacco produced in Lice District and around of Diyarbakır draws attention firstly. In Lice tobacco, the number of leaves per plant is 15-17 pieces / plant, the ratio of the length of the leaves to the width (38 cm / 23 cm), the elliptical leaf blade, dark green leaves and plant color, early flowering, the petal color is pinkish red. It is a local variety with high cigarette yield, low nicotine ratio (1-2%), protein nitrogen ratio 1%, total reducing substance ratio 15%, and the highest alkaloid ratio. In this study, the plant and quality characteristics of the local Lice tobacco variety, which has a high degree of genetic diversity, were investigated in farmer conditions and the differences with other Eastern and Southeastern Anatolian tobacco varieties were tried to be revealed.

In this study, antibacterial effects of semi-parasitic plant common mistletoe (Viscum album L.), collected from different woody host, extracts on the tomato bacterial cancer and wilt disease agent Clavibacter michiganensis subsp. michiganensis, pepper and tomato bacterial leaf spot disease agent Xanthomonas axonopodis pv. vesicatoria and tomato bacterial leaf spot disease agent Pseudomonas syringae pv.tomato were determined. The common mistletoe collected from pine, pear, acacia and mahaleb trees. The leaves and stems water extracts of common mistletoe were added to Nutrinet agar medium before autoclaving at the final concentrations of 1%, 2.5%, 5% and 10%. The bacterial concentration was adjusted to 108 cfu/ml with spectrophotometer to within an 0.2 at 600 nm. Then, 100 µl of bacterial inoculums were spread over the extracts amended media plates. As a control group, pathogens were plated on the unamended media. The study was established in 3 repetitions and repeated 2 times. At the end of the incubation period, bacteria growing on all treated petri dishes were collected and their density was measured in a spectrophotometer. Based on the results of the study, 1% and 2.5% concentration of the extracts obtained from leaves and stems of common mistletoe collected from different trees were not effective on the bacteria tested, while 5% and 10% concentration of them inhibited the bacterial growth completely (100%). Also, it was observed that there wasn’t difference on the pathogens on the basis of the host where mistletoe was collected. According to the results of this study conducted under in vitro conditions, in vivo studies should be carried out with the common mistletoe extract, which is effective on the bacterial pathogens.

Rüveyda Yüzbaşıoğlu
In the province of Tokat Turkey has an important place in terms of agricultural fertilizers and manure in order to demonstrate the environmentally conscious manufacturer 88 were interviewed. It was observed that the producers interviewed within the scope of the research are in the age range of active working age and have a socio-economic structure that makes a living from agricultural income. Factors such as age / education have a great impact on the economic structure as well as on production. Since income will be the biggest indicator of the economic structure, the income status of the producers has been investigated. Annual average agricultural income of producers is 22,311.36 TL, while non-agricultural income is calculated as 24,886.32 TL. Thus, it can be said that the average annual income of the producers is 47,197.68 TL. Here is what producers think about the residue after using the fertilizer; 48.86% of them thought that there would be manure residues and that it would have a negative impact on the environment, 43.18% of the manure would accumulate in the soil and underground water sources, 15.91% of the manure would be washed away in various ways, 11.36% had no idea about the manure residue and 6.82% that some fertilizers will leave residue in the soil. When the econometric relationship between the type of producer (the producer who only farms and works in non-agricultural insured work) and the idea that the fertilizer will accumulate in the soil and groundwater resources, it was determined that there is a significant and positive relationship. In other words, it can be said that producers have knowledge about the factors that cause environmental pollution. However, it continues to fertilize unconsciously without thinking that environmental pollution will harm them over time. This result once again highlights the importance of the training need.

Aslı Albayrak | Gülden Başyiğit Kılıç
Consumer demands for raw or unprocessed foods increased due to consumers’ awareness of the importance of a healthy life. However, searching alternative techniques instead of heat treatment is an important issue for the industry in order to enhance the microbiological quality. Non-thermal techniques are encouraged because of their effectiveness on the preservation of natural aroma, flavor and microbiological quality without causing any change in the structure of the product. Plasma technology is one of these alternative techniques. Plasma technology, known as the fourth state of matter, is known as the partial ionization of positive and negative ions, free radicals, charged particles and molecules in electron and photon form. Plasma is usually forms or formed by electric or electrical discharge or by a strong radiation effect. Plasma is classified according to its temperature, thermal equilibrium, and pressure. Cold plasma technique is used in foods for contaminated surfaces and cleaning of medical instruments. In this review, plasma technology applied to foods and their effects are presented.

Biocomfort conditions, which are related to climate parameters, are a factor that affect almost every aspect of people’s lives. Compatibility in terms of biocomfort also brings many advantages and disadvantages in areas where tourism activities are carried out. For this reason, it is of great importance to identify areas that are suitable and not suitable for biocomfort during the tourism season, especially in areas where tourism activities are carried out. In this study, with the help of GIS, it was aimed to determine the areas that are suitable and not suitable for biocomfort in the city of Samsun in June, July, August and September by using the summer temperature index (Summer Simmer Index = SSI). As a result of the study, it was determined that 1.41% of the province in June and 16.65% in September remained in the cold zone. Apart from this, it was determined that 11.58% of the province in June, 33.27% in July, 21.77% in August and 14.3% in September remained in the second generation, which is considered the most comfortable belt.

With this research, it was aimed to investigate the content of some heavy metals (Cu, Zn, Fe, Mn) and macro minerals (Mg, Ca, K, Na) in the water resources that meet the water needs of livestock in Iğdır. Water samples were collected from natural springs, surface waters, wells and drilling waters, Aras river and its branches in the region. The data obtained were classified in two different ways and statistical analysis was performed. 1. According to the districts; Central District, Tuzluca, Karakoyunlu, Aralık. 2. According to the type of water resources; Ağrı Mountain spring waters, Ağrı Mountain surface waters, Mountain spring waters, Mountain surface waters, west of Aras river and it’s canals, east of Aras river, Well and Drilling waters. Mineral levels of the water samples were measured by using Atomic Absorption Spectrometer with flame system. According to the district assessment, it was seen that Tuzluca district had lower values compared to other districts. When evaluated according to the type of water source, water mineral content was determined to increase as the waters flowing forward on the surface after reaching to the earth surface It was even found to have become unfit for consumption towards the end. Consequently, with this research, the levels of some heavy metals and macro minerals in the waters used for livestock in the Iğdır region were revealed for the first time with their details. Except for the waters of the East Aras river, the waters of the Iğdır region were found to be of usable quality for animal husbandry.

Heavy metal environmental contamination consequent of anthropogenic factors has become a global concern with cadmium and lead constituting a major public health, livestock and ecological threat. This study, therefore, uses goats (as sentinel animals) raised in 2 different regions based on their mining history (previous and existing) to evaluate exposure to cadmium and lead and their consequent toxicities and pathological changes. A total of 130 goats (composed of 88 goats which constitute the suspected exposure (SE) group and 44 goats, the suspected unexposed (SU) group) were sampled. Blood and tissue samples (liver, kidney and muscles) were analysed for lead and cadmium levels using Atomic Absorption Spectrophotometer along with the complete blood count analysis. The mean blood lead levels (BLLs) and cadmium levels (BCLs) in the goats from the SE groups were 14.59 and 3.12 µg/dl respectively, which were significantly higher than the SU groups (9.23 and 0.46 µg/dl respectively) A significantly higher frequency of goats in the SE (93.18%) also had an elevated BLLs compared to the SU group (78.57%). The levels of tissue lead and cadmium in both the SE and SU groups were found significant and higher than the FAO/WHO maximum limits. The packed cell volume, red blood cell count, and haemoglobin concentration were found significantly lower, and the platelet count and some leucocyte parameters (total white blood cell, neutrophil, eosinophil, and monocyte count) were found significantly higher in the SE group. The elevated cadmium and lead level in both groups further highlight the ubiquitous spread of cadmium and lead environmental contamination in both study regions and the direct risk of exposure to human and animals in Nigeria. The relative differences in the observed pathological changes in the two study groups also suggest the influence of the environmental heavy metal pollution and exposure levels on health.
