Ayla Arslaner | Mehmet Ali Salık
In this research, some physicochemical and microbiological characteristics and mineral compositions of marmalades produced by traditional method using Berberis integerrima Bunge (purple barberry), Berberis vulgaris L. (pink barberry), Rosa pimpinellifolia L. (black rosehip), Rosa canina L. (pink rosehip), Malus sylvestris Miller (sour apple), and Vaccinium corymbosum L. (blueberry) wild fruit naturally grown in Bayburt and Trabzon provinces were determined. As a result of the research; pH 2.56-4.18, titration acidity (in terms of citric acid) 0.62-3.40%, dry matter 53.65-64.90%, water soluble dry matter 52.28-64.53%, water activity 0.818-0.894 and HMF (5-hydroxymethyl-2-furfural) were detected in the range of 5.81-53.40 mg/kg. As a result of microbiological analysis, total aerobic mesophilic bacteria, coliform group bacteria and yeast-mold were not detected in any of the samples. In the marmalade samples, the macro minerals Ca, K, P and Mg are ranged from 23.56-425.12 mg/kg, 1275.74-5918.10 mg/kg, 21.98-921.26 mg/kg and 125.50-776.23 mg/kg, respectively. Of the micro-minerals Fe 4034.85-22346.74 µg/kg, Mn 531.63-15065.91 µg/kg, Zn 345.40-6250.76 µg/kg, B 2872.99-7300.37 µg/kg, and Ba were found between 689.31-6455.24 µg/kg. The results of heavy metal analysis showed that marmalade samples were within reliable limits. It is concluded that these fruits, which are not usually consumed as table, but have rich mineral composition, characteristic taste and pleasant aroma, can be evaluated in marmalade production. In the years when the yields of wild fruits are high, it can be processed into products with long shelf life such as jam and marmalade and converted into added value can contribute to the regional economy.

2020
Hamide Doğan | Sibel Silici | Ahmet Ata Ozcimen
Propolis is a special resin and wax material collected from the leaves and shells of trees, buds and shoots of plants by honey bees (Apis mellifera L.). In recent years, many researchers have studied the chemical composition, biological activity and pharmacological properties of propolis. The colour, odour and pharmacological properties of the propolis composition also vary as the composition changes depending on the plant, region, season and bee colony. Flavonoids, aromatic acids, phenolic acids and esters are the main compounds responsible for the biological activity of propolis. A number of studies have been conducted on the use of propolis or its active ingredients in the treatment of cancer. It has been observed that the use of propolis did not cause side effects according to in-vitro and in-vivo studies. Propolis should be extracted with different compounds for use in biological assays. The most commonly used compounds for extraction are ethanol, methanol, oil and water. A number of studies have been carried out showing the antitumor effect of propolis in cell culture and animal tests. The search for new drugs derived from natural products, which may function as chemotherapeutic agents and have low side effects, has increased in recent years. Combination with antioxidant therapy may improve the side effects of chemotherapy on leukocytes, liver and kidney, thus increasing the effect of chemotherapy with dose increase.

Nazife Yiğit Kayhan | İlkay Çorak Öcal
Akrepler, Arachnida sınıfında yer alan zehirli arthropodlardan olup, bilinen en eski karasal eklembacaklılardır ve yaşayan fosiller olarak da tanımlanmaktadırlar. Akrepler kendilerine özgü bir takım özelliklere, özel yapılara sahip olmaları ve zehirlenme vakalarına sebep olmaları nedeniyle çeşitli araştırmalara konu olmuştur. Ancak, akreplere özgü bir duyu organı olan ve tarak organı olarak da bilinen pektin organın yapısı hakkında çok fazla bilgi bulunmamaktadır. Bu çalışmada, Protoiurus kraepelini (von Ubisch, 1922) akrebinin tarak organ yapısı ışık mikroskobu ve taramalı elektron mikroskop (SEM) kullanarak çalışılmış, detaylı morfolojik ve histolojik özellikleri belirlenmiştir. Örnekler Eğirdir (Isparta, Türkiye)’de yapılan arazi çalışmalarında toplanamıştır. P. kraepelini’nin tarak organı diğer akreplerde olduğu gibi bir çift olarak mesosomal ikinci segmentin ventrolateralinde yerleşmiş olup genel mimariye uygun olarak marjinal lamella, median lamella ve pektinal dişler olmak üzere üç kısımdan oluşmaktadır. Aynı zamanda bu yapılar üzerinde yer alan duyusal kılları, pektinal dişler üzerindeki peg sensillanın morfolojileri incelenmiştir. Bu çalışmada, ilk kez P. kraepelini’nin tarak organının histolojisi ortaya konulmuş ve yapı - fonksiyon arasındaki bağlantı uyarınca olası fonksiyonları tartışılmıştır.

2020
Gülistan Erdal | Hilmi Erdal | Adnan Çiçek
This paper studied the effect of livestock support policies applied in Turkey by a emprical study. The study was carried out based on the analysis of the data collected through surveys with a total of 478 livestock enterprises in the TR83 region (including Amasya, Çorum, Samsun and Tokat provinces). The enterprises included in the survey study were grouped into three categories by the number of their animals. Binary Logistic Regression Model was applied in order to define the policy-based support payment utilization probabilities of the enterprises and the factors affecting them. It was determined that approximately 45% of the enterprises cannot utilize livestock supports. The most utilized support items by the enterprises were determined as calf support, support per animal, forage plant support and raw milk support. A total of 65% of the enterprise owners think that the support amount per animal is insufficient, but regard the mentioned support item as the most important factor for improving animal presence. The utilization rates vary in terms of enterprise scales on the other hand. The support utilization likelihood of medium-scale enterprises is 3.1 times higher than small-scale enterprises, and this likelihood is 1.7 times higher for big-scale enterprises when compared with medium-scale enterprises. The study recommends that some regulations are needed in support of policies to enable a better improvement in animal presence and a homogenous distribution of support payments.

Muhittin Yağmur Polat | Abdullah Beyaz | İbrahim Çilingir
Liquid chemical fertilizers are widely used in modern agriculture. The pH values of these fertilizers are important in terms of their effectiveness in the field application and their effect on the soil-water pH balance. Therefore, it is necessary to measure the pH and other properties of liquid fertilizers with fast, practical and inexpensive methods. With the advancing technology, pH value has been started to measure more accurately and efficiently with the help of low-cost devices. In this study, a low-cost pH meter was developed using a low-cost pH sensor, an Arduino UNO R3 microcontroller board, and a software written in the C/C++ programming language. The developed pH meter was used to measure the pH values of liquid chemical fertilizers. Close variations were observed between the values obtained from it and the values measured by an accredited, laboratory-type pH meter. According to the pH measurements of the two pH meters, R2 ranged 88.1% to 99.3%, average error range 0.14 to 0.28, and average error percentage ranged 1.56% to 6.81% for three different types of liquid fertilizers. In light of these results, it was shown that the developed low-cost pH meter can be useful for practical pH measurement applications.

This study aimed to evaluate the effect of compost from chicken manure, NPK fertilizer and the mixture of both fertilizers on agronomic parameters of four varieties of cassava (Yacé, Bonoua, Six mois and Alleda agba) in Côte d’Ivoire. The field experiment was carried out under a randomized complete block design with three replicates on a ferralitic soil during two season-cycles. The results showed that the different fertilizers stimulated plants growth and tuberous roots production. The highest number of stems (3) and leaves (66) was obtained with the mixture of NPK and compost applied on the variety “Bonoua”. All varieties that received the compost mixed with NPK produced more leaves with a dominance of the Bonoua variety (65.57). The highest number of tuberous roots (5.58), the heaviest weight per root (6.13 kg) and the highest yield (61.37 t/ha) were obtained while using the mixture of compost and NPK as fertilizer and “Bonoua” as variety. Thus, mixing compost from chicken manure and NPK can be recommended to improve cassava productivity in Côte d'Ivoire on a ferralitic soil.

The aim of this study was to investigate the effects of organic copper supplementation (0, 5, 10 and 20 mg/kg) in the commercial diet on performance, egg quality and haematological parameters in laying quails. In this 10-week trial, a total of 80 laying quails, aged 22 weeks, were randomly distributed among four experimental groups. Each experimental group contained four replicates of five female birds each. The addition of organic copper to the diets did not statistically affect egg production, egg weight, egg mass, feed conversion ratio, damaged eggs, egg shape index, Haugh unit, and blood parameters except neutrophils and mean corpuscular haemoglobin. Compared to other groups, body weight change was decreased by the addition of 20 mg/kg organic copper, and feed intake was decreased by the addition of 10 mg/kg copper in the quails. The addition of 20 mg/kg of organic copper to the quail diets significantly decreased the eggshell breaking strength and eggshell weight, while it significantly increased the eggshell thickness compared with the control group. The neutrophil and mean corpuscular haemoglobin were increased by the addition of 10 and 20 mg/kg organic copper, respectively, with compare to other groups. It can be said that up to 10 mg / kg of organic copper can be added to commercial quail diets, but its addition at 20 mg/kg negatively effects on some blood parameters as neutrophil and mean corpuscular haemoglobin in quails.
