Urban green spaces are areas established to meet the recreational needs of urban people. Although green spaces vary from country to country and region in terms of plan and design features, they were basically created to allow people to meet with nature. Parks are the basic components of urban landscapes that provide environmental and social functional value. Urban parks, in particular, provide spaces for outdoor physical activities. In order to take advantage of the opportunities of activities in the parks, users must have convenient access to these resources. One of the most important aspects for researching the use and potential benefits of urban green spaces is the assessment of their geographic accessibility. The widespread use of smart city systems and the gradual expansion of their usage areas increase the importance of spatial analysis. Spatial analyses are used in today’s urban management in the processes of determining social needs, identifying current problems, and putting forward solutions. When spatial analyses are used together with GIS, the field of application develops even more, and it supports local governments in responding to the changing demands of the society for a better life. In the study, the adequacy and accessibility of 160 city parks in Konyaaltı District of Antalya Province were examined. In terms of the adequacy of the parks, the area value of 10 m2 per person determined with the Construction Plan numbered 3194 was taken as basis. In terms of accessibility, distance values of 200, 400, 800, 1,200 meters were examined. Neighborhood boundaries and population information were obtained from the relevant units, and Arc-GIS software was used in the analysis. It was determined that the parks in Konyaaltı district were insufficient in terms of adequacy and accessibility. Finally, suggestions were made in terms of increasing the adequacy of the parks and ensuring accessibility.

This experiment was conducted to determine the effect of active yeast (AY) and inactive-stabilized yeast (Thepax) supplementation to the rations in different levels on broiler performance. In the experiment carried out according to the randomized plot design, there were 5 different treatment groups as control group (Group 1), 0.1% Thepax (Group 2), 0.2% Thepax (Group 3), 0.1% AY (Group 4) and 0.2% AY (Group 5). In the experiment, the effects of active and inactive yeasts on body weight gain (BWG), feed consumption, feed conversion rate, carcass weight (CW), carcass yield (CY), abdominal fat amount and mortality were investigated. In the present experiment, the final live weight, the cumulative feed consumption and feed conversion were insignificant. The statistical difference between the groups in the experiment was significant in carcass weight, but insignificant in the amount of abdominal fat and mortality rate. Inactive-stabilized yeast (Thepax 0.1%) was more effective than 0.2% AY on BWG. Only 0.1% Thepax increased the CW besides CY was high in 0.1%, 0.2% Thepax and 0.1% AY groups. It has been observed that active and inactive yeasts are used in broiler chickens without any problem.

Probiotic yoghurt with fruit was produced to enrich the intestinal flora of infants and to prevent various ailments in infants when the flora is inadequate. Peach, apple and pear purees (10% and 20% each), cow milk, milk powder, starter culture (combination of Streptococcus thermophilus, Lactobacillus delbrueckii ssp. bulgaricus, Bifidobacterium infantis, Bifidobacterium bifidum, Bifidobacterium longum and Lactobacillus paracasei) were used in the production of probiotic yogurt for babies. Some properties of yoghurt samples were investigated during fermentation and on the 1st, 7th, 14th and 21st days of storage. After ten hours of fermentation, the lowest pH was observed in samples with apple puree. It has been determined that syneresis increases with increasing concentrations of fruit purees. The water holding capacity was less in yoghurts containing fruit puree compared to control yoghurt and in 20% fruit puree compared to yoghurts containing 10% fruit puree. The number of L. bulgaricus generally increased in all samples during storage. It was determined that the number of S. thermophilus in control sample was higher than other samples during storage. The number of L. paracasei and Bifidobacterium spp. decreased during storage. While the control sample remained probiotic until the 14th day of storage, other samples lost its probiotic properties before the 7th day of storage. Considering that the number of probiotic microorganisms in a probiotic product should be at least 106-107 CFU/g according to FAO, it has been decided that the most suitable fruits for probiotic yogurt with fruit puree are peach and apple, respectively. Considering the structural features, it is more appropriate to use 10% fruit puree, and considering the probiotic feature, it is more appropriate to use 20% fruit puree. Choosing the appropriate packaging and fixing suitable storage conditions will help probiotic microorganisms to preserve their vitality for a long time.

Essential oil composition, antimicrobial activity and flavonoid contents of leaf-fruits of Cedrus libani and Pinus nigra subsp. pallasiana were determined with GC-MS, disc diffusion method and HPLC in three different period. When the essential oil composition of leaf and fruits of P. nigra ssp pallasiana collected in April, July and September, major components were α-pinene, β-pinene, limonene, β-caryophyllene ve germacrene-D. On the other hand, additionally to these contents, myrcene and α–terpineol were also detected in C. libani. According to HPLC analysis, rutin, quercetin, kaempferol, naringin and resveratrol flavonoids were detected in different proportions. While rutin (154.33 µg g-) and resveratrol (20.02 µg g-) has the highest ratio in C. libani, quercetin (9.65 µg g-) and naringin (9.31 µg g-) were detected in P. nigra subsp. pallasiana along with rutin (39.66 µg g-). According to the antimicrobial activity results the essential oils of C. libani obtained in April has produced higher activity than that of July and September. On the contrary, the essential oils from P. nigra subsp. pallasina have produced the best antimicrobial activity on September compared to April and July. As a result, C. libani and P. nigra subsp. pallasiana essential oils have a composition showing antimicrobial activity and their harvesting season should be determined for the best and effective content.

This study was carried out between 2017 and 2018 to determine physical and chemical influences of two drying methods (drying on wooden fruit drying trays and drying cloths), two harvesting periods (commercial / physiological maturity and late harvest), and two harvesting methods (harvesting by hand and shaking) on dried fruit samples of Hacıhaliloğlu and Kabaaşı cultivars. Titrable acidity, browning level, total phenolic content, antioxidant activity (ABTS), color (L*, a*, b*), pH, humidity and water activity (aw) parameters of dried fruit samples were examined. Results indicated that different harvesting periods, methods and drying methods significantly affected almost all fruit quality parameters. L value was higher in apricots dried on trays than dried on the cloths. L* values of dried apricots ranged from 27,13 to 54,74. Similarly, moisture content and water activity values were also found to be lower in apricots dried on wooden fruit drying trays than dried on clothes. When chemical parameters were examined, it was observed that phenolic compounds and total antioxidant contents decreased with fruit ripening. The effect of the applications on drying efficiency was not determined as significant, on the contrary, the individual weights of the dried apricots harvested at the late period were found significantly higher and the number of dried apricots per kilogram was lower. As a result of the study, it was concluded that in sun-dried apricot production, harvesting at late period and the drying on trays positively affected various quality parameters.

The aim of this study was to determine the reproductive characteristics, milk yield and milk quality of Primiparous Red-Holstein (RH) and Holstein-Friesian (HF) cows. For this aim, records and monthly taken milk samples of 83 RH and 14 HF raised on a farm in Aydın, Turkey were used. The averages of the first calving age (FCA), gestation length (GL), days open (DO), calving interval (CI), daily milk yield (DMY), 305-day milk yield (305-dMY), solid non-fat (SNF) and Log10 somatic cell count (Log10SCC) of milk were found to be 27.6±0.24 mo, 278.4±1.09 d, 144.0±7.12 d, 421.4±7.66 d, 22.7±0.21 kg, 6981±137.0 kg, 9.8±0.04% and 4.59±0.024 (38905 cells/ml), respectively. Except for DMY, the differences between the breeds were statistically insignificant for FCA, GL, DO, CI, 305-dMY, SNF and Log10SCC. DMY averages for RH and HF were 21.8±0.21 kg and 24.3±0.49 kg, respectively. The effect of season on FCA and the effect of lactation month on SNF and Log10SCC were also found to be statistically significant. Apart from DMY, not any significant difference was observed between RH and HF breeds in terms of the characteristics emphasized.

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.

Objective of this study is to determine plant protection problems which wheat growers encountered and their knowledge on plant protection in Sivas province. This study is carried out in the Central, Hafik, Ulas and Yıldızeli districts of Sivas province with 220 farmers. The problems which related to plant diseases, pests and weeds in wheat growers faced were also determined. Almost all farmers (99.09%) apply chemical control. Farmers decides the pesticide applications in their wheat growing areas according to own experience (84.09%), manufacturers recommendations (24.09%), the advice of agricultural experts (17.27%) and the advice of neighbours and friends (9.55%). Farmers mostly have been applying pesticides based on their own experiences. In recent years, pesticides are being used widely against diseases, pests and weeds. Some times over dose application of pesticides by farmers in judiciously resulted in environmental pollution, health problems. Also the natural enemies will be affected. Furthermore, in weed control farmers use herbicides against broad leaved weeds. It was determined that the farmers do not have knowledge about narrow leaved weeds and herbicides use against these weed species is limited. According to the results of this survey, it will be beneficial to provide training on plant protection to wheat producers in the region.

Nitrogen losses in agricultural areas cause environmental pollution. At the same time, it reduces the yield in crop production. The aim of this study is to investigate the effects of zeolite and nitrogen applications on the development of maize plant. Another aim is to reveal nitrate changes in soil. Everest maize variety was used in the study. Zeolite doses of 0, 125, 250 and 500 kg/da were applied to the soil. Nitrogen doses were applied to the soil at 5, 10, 15 and 20 kg/da. In this study, zeolite and nitrogen applications increased the plant height, cob weight and green forage yield of maize plant statistically. The highest green weed yield was 6563 kg/da in Z3N3 application and the lowest green forage yield was 4021 kg/da in Z0N0 application. Increased nitrogen doses increased the amount of nitrate in soil by significantly 1% and zeolite applications increased by significantly 5%. The results of this study would be beneficial in the application of zeolite to the soil in order to reduce nitrogen losses and to make the plant benefit more from nitrogen.
