Ecological processes that occur in a lake depend on the physico-chemical (abiotic) and biotic factors of the system and the interrelations between them. It can be concluded that the current nutrient loadings from both point and non-point sources are cause to increase eutrophic case over the years. This study indicate that the sustainable utilization of reservoir in combination with proper wastewater treatment plant and controlled use of pesticides has a potential to reduce the current nutrient loadings into Suat Uğurlu Lake. The estimated nutrient reductions that could be achieved from the management scenario would be enough to revert the lake from mesotrophic situation to trophic state. The reduction of nutrient loadings into Suat Uğurlu Lake could be achieved through the practice of Integrated Water Resource Management (IWRM), through good management. However, as long as pertinent issues of urban poverty, watershed management and public awareness and involvement in water related issues are not addressed, trophic in Suat Uğurlu Lake will remain a problem.

In this research, it was aimed to determine the adsorption, saturation reaching and desorption effects of ammonium, which is one of the parameters that should be kept in control for aquarium life, by clinoptilolite type zeolite which is a natural filtration material. In the aquarium water, Z1: 20 mg/l TAN and Z2: 40 mg/l TAN concentrations were determined to have adsorption up to Z1: 10 mg/l TAN and Z2: 24 mg/l TAN concentration at the end of the experiment period. After this phase, where zeolites had reached saturation, desorption system was created, and 2 groups were formed with 5-liter research aquariums and 3 repetitions. During the five-days test, water parameters were determined daily and at the same time of day (10.00). At the beginning of the experiment, mean values of 0.4 ± 0.00 mg / l TAN in Z1 and Z2 groups were determined at the end of the experiment as 1.55 ± 0.176 mg/l (15.5%) and 2.153 ± 0.27 mg/l (13.5%) TAN in Z1 and Z2 groups, respectively. When the data obtained in this study were evaluated, zeolite was determined to make desorption periodically in proportion with the amount of retained ammonium, when it reached the saturation. In intensive aquaculture systems or aquarium conditions, recondition of zeolite for necessary periods is recommended to be performed by considering these data.

This study was carried out to elucidate the impacts of zinc (Zn) treatments on growth, development, quality and yield of commonly sown bread wheat cultivars under field conditions of Çukurova Region. Three different bread wheat cultivars (Adana-99, Ceyhan-99 and Pandas) were experimented in randomized complete blocks-split plots experimental design with 3 replications. Field experiments were performed by two different Zn application methods; via soil and via soil+foliage. In the both trials, 0, 5, 10, 20, 30, and 40 kg ha-1 pure Zn doses were applied to the soil. 0.4% ZnSO4.7H2O solution was used for foliar Zn applications. Current findings revealed that Zn treatments had significant effects on grain yield, grain Zn concentration, grain phosphorus (P) concentration and thousand grain weight of bread wheat cultivars, but significant effects were not observed on grain protein concentrations. Soil+foliar Zn treatments were more effective in improving grain Zn concentrations. It was concluded that 10- 20 kg ha-1 Zn treatment was quite effective on grain Zn concentrations.

The research was conducted with the aim of determining the social and economic factors which are effective on the adoption of new technologies at dairy farms in the province of Konya. The data used in the research was obtained on a volunteer basis by questionnaire technique from 128 dairy farms determined with stratified sampling method that is one of random sampling method. 51.56% of enterprises investigated were high innovators and 48.44% of enterprises were low innovators. In conclusion, it was determined that the milk yield, enterprise income, education of enterpriser, family size, number of animals, existence of land, case of receiving services of consultancy and frequency of using mass media tools made positive contributions to adoption of innovations by enterprises in the research field. But the training level decreased as the age of enterpriser increased in the research field. This case retards the adoption process of innovations and deescalates the use of new technologies in the enterprises. The young farmers come to the forefront in the adoption and implementation of innovations.

In this study, the phenological characteristics of some apple varieties grown in the Kalecik district of Ankara province, the number of days between effective heat summation requirements, and phenological phases were determined. The research was conducted on Royal Gala, Granny Smith, Jersey Mac, Spur Golden and Red Chief apple varieties. The threshold temperature of +10°C was accepted as the temperature value for the determination of the heat summation requirements of the varieties. The effective heat summation above +10°C during the growing season of varieties was determined as 819.1-1986.3°C days in 2015 and 865.1-2031.2°C days in 2016. The number of days from full bloom to harvest was 85-75 days in 2015 and 132-219 days in 2016.

Rapid urbanization in developing countries involves unplanned migration, unemployment and poverty. The steady shrinking of rural areas and the use of agricultural land for other purposes are progressively increasing the pressure on natural resources. This development on the one hand increases the risk to food security, and on the other triggers climate change. The rural population who migrate to the cities or who are absorbed into urban areas continue their agricultural activities in the urban in order to provide themselves with an income or to maintain their food security. In the big cities of the developed world, contact with nature is kept by means of hobby gardens, recreational areas and urban and suburban plant and animal farming, and creative ideas such as roof gardens can be found. This development, known as urban agriculture, is practiced by 800 million people in the world. Urban agriculture has many economic, social and environmental benefits, but it may also have risks and adverse effects. In this study, the developments in this area in Turkey and the world are presented, and all aspects of its effects and outcomes are discussed.

Günümüzde insan ömrünün en az %80’i kapalı mekanlarda geçmekte ve bu kapalı mekanlardaki iç ortam hava kalitesi insanların sağlıklarını ve performanslarını doğrudan etkilemektedir. Özellikle CO2 miktarı belirli seviyelerin üzerine çıktığında baş ağrısı, baş dönmesi, yorgunluk, konsantrasyon bozuklukları, boğaz ve burun tahrişi, burun akıntısı, öksürük ve göz akıntıları gibi pek çok rahatsızlığa sebep olmaktadır. İç ortamdaki CO2 miktarını etkileyen en önemli faktör canlı metabolik faaliyetleridir. Solunumla artan CO2 miktarı fotosentezle azalmaktadır. Dolayısıyla iç mekanlarda bitkiler CO2 miktarını azaltmak amacıyla kullanılabilir. Ancak bitkilerin iç ortamdaki hava kalitesine etkisi konusunda yeterli bilgi bulunmadığından, bitkiler iç ortamdaki CO2 miktarını azaltmak konusunda etkin ve bilinçli bir şekilde kullanılamamaktadır. Bu çalışmada iç mekan süs bitkisi olarak en sık kullanılan bitkilerden birisi olan difenbahyanın (Dieffenbachia amoena Gentil) iç ortamdaki CO2 miktarına etkisinin sıcaklığa bağlı olarak değişiminin belirlenmesi amaçlanmıştır. Çalışma sonucunda difenbahyanın karanlık ortamda yaptığı solunumun sıcaklığa bağlı olarak önemsiz düzeyde olduğu belirlenmiştir. Ancak ışık bulunan ortamda en yüksek etkiyi 23-24℃ sıcaklıklarda gösterdiği, 30°C sıcaklıktaki fotosentez hızının, 20°C dekinden düşük ancak 15°C dekinden daha yüksek olduğu belirlenmiştir.

Water loss kinetics in osmotic dehydration of cone-shaped fruits and vegetables was modeled on the basis of diffusion mechanism, using the Fick’s second law. The model was developed by taking into account the influences of the fruit geometrical characteristics, initial water content of fruit, water diffusion coefficient in fruit, and the water concentration in hypertonic solution. Based on the obtained model, it was shown that the water diffusion coefficient and the initial water concentration of fruit have direct effects on the dehydration rate and also inverse influence on the dehydration duration. The geometrical parameters of fruit and water concentration in hypertonic solution showed direct effect on the dehydration duration as well as inverse effect on the dehydration rate. The presented model seems to be useful tool to predict the dehydration kinetics of cone-shaped fruit during osmotic dehydration process and to optimize the process prior to perform the experiments.

Antibiotic resistance is being constantly developed worldwide. Coagulase Negative Staphylococci (CNS) and Staphylococcus aureus are common causes of bovine subclinical mastitis. Bioactive compound of medicinal plants shows anti-microbial, anti-mutagenic and anti-oxidant effects. The anti-bacterial and anti-oxidant activities of Liquidambar orientalis (L. orientalis) extracts on subclinical mastitis causing bacteria in cows have not been reported to date. The aim of the present study was to examine anti-bacterial and anti-oxidant effects of L. orientalis leaf extracts on S. aureus and CNS isolated from cows with subclinical mastitis symptoms. In this study, 3.2 mg/mL minimum inhibitory concentration (MIC) of ethanol extracts of L. orientalis has shown to be a most potent anti-bacterial and anti-oxidant for all isolated bacterial species from mastitis cows. In this study, it was investigated anti-bacterial and anti-oxidant potentials of acetone, methanol and ethanol extracts of the L. orientalis. The acetone extract showed maximum inhibition zone against S. aureus numbered 17 (12 mm). In addition to anti-bacterial properties, anti-oxidant activity of L. orientalis extract was examined by ABTS [2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid)] free radical assay. Trolox was used as a positive control anti-oxidant. Ethanol extract exhibited a strong anti-oxidant activity like Trolox anti-oxidant which was effective at 2.58 mM concentration. Bioactive compounds of sweet gum may be useful to screening mastitis causing bacteria for clinical applications.
