2020
Abdurrahman Pirinç | Abdullah Özbilgin | Oğuzhan Kahraman | Esad Sami Polat
In this study, nutritional values of silages made from seed pumpkin residues were investigated. Pumpkin residues collected from Konya region were put into silo in vacuum sacks with various additives. As additives, straw, inoculant containing lactic acid bacteria or a mixture of both in certain proportions were used. After the silos were opened, their pH was determined and then samples were taken to determine the essential fatty acid compositions and nutrient analyses were done. Natural pumpkin (Group 1), natural pumpkin + inoculant (100ppm) (Group 2), withered pumpkin + 15% straw (Group 3), withered pumpkin + 15% straw + inoculant (100ppm) (Group 4) such that the fourth group is formed. Dry matter values of pumpkin groups are Group 1 7.89%, Group 2 6.62%, Group 3 12.22% and Group 4 12.25% respectively. Their pH is 3.78 in Group 1, 3.71 in Group 2, 3.86 in Group 3 and 3.82 in Group 4. The crude protein ratio in the experimental groups was determined in the highest Group 2 (14.97%) and the lowest in Group 3 (10.56%). NDF rate was determined in the highest group 4 (49.74%) and the lowest in Group 2 (28.51%). In addition, the highest ADF rate was determined in Group 4 (37.91%) and the lowest in Group 2 (24.90%). There was a statistically significant difference between the research groups in terms of ethanol content. Acetic acid and propionic acid content was found statistically significant between groups. As a result, when the pumpkin residues are silaged, it can be used as feed material in animal feeding. In addition, it can be said that pumpkin residues can be evaluated in different areas in the high amount of Ethanol content resulting from silage production.

The major antimicrobial proteins in donkey milk are lysozyme, lactoferrin, lactoperoxidase and immunoglobulins. Lysozyme has an important role in the host defense by way it inhibits the pathogenic bacteria. The aim of this study is to investigate the Lysozyme (LYZ) gene polymorphism in 82 donkeys reared in Thrace region of Turkey. 716 bp long partial 5’ UTR, exon 1, intron 1, exon 2 regions of LYZ gene were amplified and PCR products were analyzed via DNA sequencing. Three novel single nucleotide polymorphisms (SNPs) were identified as g.1782775A>G, g.1782924A>G and g.1782960T>C in the first intron of LYZ gene. The partial DNA sequence of LYZ gene in donkeys was reported in the present study and sequences of LYZ were entered to NCBI Genbank database with the accession number: MK984689-MK984692. This SNP may have an effect on immune system and milk traits in donkeys and additional studies are needed to confirm this assumption for donkey breeding.

Hande Demir | Mustafa Kemal Yıldız | İsmail Becerikli | Sevcan Unluturk | Zehra Kaya
This study aims to compare UV-C irradiation and conventional heat treatment to produce pasteurized onion juice used as a meat marinating agent. The process conditions maximizing the inactivation of target microorganism Escherichia coli K-12 were; 0.5 mm sample depth, 30 min irradiation, 7.5 mW/cm2 UV incident intensity for UV-C and, 74.5°C and 12 min for heat treatment. Except pH and non-enzymatic browning index, differences between physicochemical properties of raw, UV-C and heat-treated onion juices were significant. Springiness and chewiness of unmarinated beefsteaks were higher compared to the ones marinated with the fresh and pasteurized onion juice (UV-C and heat). Pasteurization of onion juice (UV-C and heat) did not significantly affect general liking scores compared to beefsteaks marinated in untreated onion juice.

2020
Aybike Bayraktar | Ismet Boz
While the use of pesticides in plant production has positive effects on yield and quality, it has negative effects on human and environmental health. The environment is polluted by the intense and unconscious use of chemicals in agriculture, and the absence of environmentally friendly agricultural methods. This causes problems in the long term, such as reduced biodiversity and disruption of natural balance. This study is important because there are many problems such as the producers' failure to effectively apply methods of combating diseases, pests, and weeds in agricultural production, the use of unnecessary and wrong doses of pesticides, and the methods other than chemical control are not preferred. The aim of this study was to examine the attitudes and behaviors of farmers towards use of pesticides in Çarşamba District of Samsun Province. For this purpose, a survey was conducted with 112 farmers determined by stratified sampling method. According to the findings, most of the farmers in the region do not prefer other methods different form chemical control methods. While farmers found the effectiveness of pesticides at a medium level, they found the price levels of pesticides high. While there is a perception that over-using pesticides adversely affects the environment, biological control methods are not known enough. Various research, education, and extension studies should be carried out for farmers to use pesticides more consciously, and to apply methods other than chemical control.

(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.

Husbandry has a special importance for people who live in rural areas in terms of agricultural income and profitability due to some contributions such as; providing cash flow throughout the year, product processing, balanced usage of labour force, and risk diversification. According to FAO data of 2017, Turkey’s ratio in the world’s total cattle existence was 0.99%, and it had a 2.78% ratio in total milk production. According to TSI data between 2004 and 2018; the number of total cattle reached 17.042.506 with a ratio increase of 4.62%, and the annual milk production amount reached 20.036.877 tons with a ratio increase of 7.23%. Within the period of time that is mentioned above, the contribution ratio of culture breed cattle in milk production reached 61.39% from 33.63%. However, in terms of milk cow productivity, Turkey is the 57th in the world. The cities of Konya, İzmir, Erzurum, Balıkesir, and Diyarbakır provide 21.74% of Turkey’s total milk cow existence, and 22.77% of the milk production total. In terms of agricultural subsidies which are provided by Ministry of Agriculture and Forestry, husbandry took a share of 25.79% from the 14.5 billion TL total agricultural subsidies in 2018. According to the research results, directly or indirectly, husbandry contributes to decreasing development level differences between regions, and it helps to improve enterprises’ income levels in rural areas.

Aybüke Kaya | Songül Bay
This study was carried out to evaluate the socio-economic structure and organic farming activities of grape producers in Besni. A face-to-face survey was conducted with producers producing organic grapes. Data were obtained by interviewing a total of 50 producers. The number of organic products grown between 2005 and 2018 increased from 205 to 213 in Turkey. The number of producers engaged in cultivation in this area has increased more than 5 times compared to 2005. It reached nearly 80.000 in 2018. The area of organic vegetable production increased from 203.811 to 626.884 hectares in Turkey. While the production area increased 2.5 times, the production amount increased almost 4 times. Today, a variety of products in organic vegetable production, planting area, the number of farmers has increased in Turkey. The findings were obtained education level of the producers, the number of individuals in the family, record keeping, annual total income, newspaper reading, grape yield, grape cultivation area, property and rental land, credit usage, weed control, organic farming knowledge level, organic farming by using variables such as thoughts and grape variety. There are serious differences between conventional agriculture and organic farming. The family structure is effective in production activities. It has been determined that the thoughts of organic farming have changed depending on the age and experience of the producers. Organic grape producers have turned to organic farming due to their desire to sell their products at higher prices with state supports. Also, it has been suggested that organic farming is important in terms of the sustainability of living life all over the world. Increasing producer income and environmental awareness are among the main reasons for the transition to organic farming.

Azim Şimşek
The aim of this study was to investigate the effects of different cooking techniques and internal cooking temperature applications on the oxidative stability of hamburger patties. For this purpose, 4 different cooking techniques (boiling, oven-roasting, grilling and microwave) and 2 different internal cooking temperatures (72°C and 78°C) were used. Microwave cooking caused the highest cooking loss values. The higher cooking loss values were determined as a result of the 78°C internal cooking temperature application. Lower pH values were obtained by microwave cooking. Boiling increased L* and a* values, whereas decreased b* values compared to other cooking techniques. While a* values decreased with storage in hamburger patties, b* and HUE angle values increased. The lower thiobarbituric acid reactive substances (TBARS) and lipid hydroperoxide (LPO) values were determined in samples cooked with microwave or boiling technique. Even though there was no TBARS difference between different internal cooking temperature applications, the higher LPO values were determined in the application of 78°C internal cooking temperature. The results of this study showed that less oxidative changes could be occurred by the use of either microwave or boiling technique in hamburger patty production.

2020
Ulku Baykal
Powdery mildew is a serious disease of economically important hazelnut crop in Turkey. Hazelnut production has been extremely affected by the disease in terms of quality and quantity. The disease is caused by two different fungi, namely Erysiphe corylacearum and Phyllactinia guttata. E. corylacearum has been shown to be the responsible one predominantly for the recent economic damage. The fungi produce a mycelium network on hazelnut plants before they sporulate and visually detected. Early detection of these pathogens is important for management as well as understanding their spread and epidemics. In this study, a PCR assay was developed for the detection of both pathogens from hazelnut plant leaves by targeting their ribosomal DNA genes in their internal transcribed spacer (ITS) regions. Two sets of specific primers were designed for the detection of E. corylacearum and P. guttata at an early stage of infection. As a result of PCR, a specific band of 578 bp was observed. The amplicon sequencing confirmed the presence of only E. corylacearum, but not P. guttata. Therefore, this PCR-based test can identify plants that are infected with powdery mildew before they show any visual signs. From there, the infected plants can be treated or removed before the fungus has a chance to produce spores that infect neighboring plants. These results would help tackle the eradication of powdery mildew.
