Sule Gurkan | Ertan Taskavak | Deniz Innal
This study aims to determine various relationships between liver, gonad and body weights of the two pipefish species caught in two breeding seasons from the Bafa Lake (Muğla) coasts between 2014 -2016. Using beach seine-net in the lake, a total of 208 pipefish specimens (79 Synathus abaster and 129 Synathus acus) were sampled. L-W relationship and Fulton condition factor were W = 2E - 0.94.01, 0.035 ± 0.009 in S.abaster specimens. Also LW relationships and condition factor were W = 8E-0.93.83 , 0.033 ± 0.01 in S. acus. On the other hand mean ± SD of HSI and GSI values were 2.18 ± 1.65 and 7.69 ± 7.12 respectively. In S.acus values 3.22 ± 3.13 and 5.49 ± 5.12 as well. The decrease in HIS and K values, provides sufficient information to claim that species in the lake spend all energy requirement obtained with proper feeding to growth and gonad development.

Adnan Bozdoğan | Kurban Yaşar
This research was performed to elucidate the effects of temperature on the degradation kinetics of anthocyanins in shalgam beverage. Shalgam beverage was produced according to traditional production method. Then, it was kept at three different temperatures (65°C, 75°C, and 85°C) for 12 hours, and the relevant quantities of anthocyanins were determined thereafter. The research revealed that degradation of the anthocyanins was well described with a 1st-order reaction kinetics model and the R2 values varied in the range of 0.9059-0.9715. Activation energy of the reaction was determined to be 48537 Joule/mole. The half-lives of anthocyanins at 65°C and 75° C, and 85°C were found to be 138.63, 136.72, and 51.57, respectively. Compared the half-life periods at different temperatures, anthocyanins were found to be more resistant at 65°C and 75°C than at 85°C.

Buket Aşkın
Peynir üretimi ile eski zamanlardan bu yana önemli bir yere sahip olan Kırklareli ilinde önemli ticari potansiyele sahip olan iki farklı peynir, Kırklareli Beyaz Peyniri (KBP) ve KBP ve KEKP üretiminde belli oranlarda koyun sütü, keçi sütü ve inek sütü karışımı kullanılmaktadır. Kırklareli peynirlerini ayırt edici kılan temel bazı özellikler mevcuttur. Bu özellikleri coğrafi yapı ve iklim koşullarına bağlı olarak ortaya çıkan doğal bitki örtüsünün getirdiği etki, peynir hammaddesi olan sütün taşımış olduğu farklılıklar, son olarak ve en önemlisi ise üretim yöntemi ve olgunlaşma sürecinde yer alan temel farklılıklar ile belirtildiği gibi süregelen tarihsel ustalık şeklinde özetlemek mümkündür. KBP ve KEKP taşıdığı farklılıkları bir zincir gibi hayvan beslenmesinden, süte, sütten peynire yansımaktadır. İlin botanik kompozisyonunu oluşturan türlerin oranları hayvanların yemini oluşturmaktadır. Botanik özelliklerine göre Kırklareli meralarında yaygın olan bitkiler buğdaygiller (Poaceae), baklagiller (Fabaceae), geniş yapraklı otlar (Asteraceae, Apiaceae, Lamiaceae vd.) ve çalılardır (Fagaceae vd.). Bu 3 farklı bitki grubunun süt ve peynir üzerine farklı şekillerde etkileri bulunmaktadır ve protein miktarı, yağ oranı vb. gibi en temel kalite kriterlerini etkilemektedir. Bunların dışında sütün mikrobiyal yükünün çok düşük olması ile başlayan ve üretim koşullarının getirdiği birçok farklılık ta mevcuttur. İlde üretilen sütlerin AB kriterlerine uygun olması, öncelikle düşük pastörizasyon sıcaklığı gibi çok önemli bir avantajı beraberinde getirmektedir. Üretimlerinde yalnızca inek sütü kullanılabileceği gibi koyun sütü, keçi sütü ve inek sütü karışımı da kullanılabilir. Karışım oranları ise %30-%45 koyun sütü, %25-%40 keçi sütü, %15-%30 inek sütü şeklindedir.

Sadettin Ünsal
Pesticides have both acute and chronic effects on humans and all other warm blooded living things. In pesticide applications, few of the amount used reaches the target organisms, whereas the rest mixes into the ecosystem and leads to the deterioration of the ongoing natural balance. Therefore, growing attention has been given toward the development of alternate environmentally friendly pesticides/insecticides that would aid an efficient pest management system and also prevent chronic exposures leading to diseases. In this context, plant-derived natural products are considered valuable candidates to reverse this negative trend. Botanical pesticides are relatively safe, degradable, and are readily available sources of biopesticides. Neem is an ideal alternative candidate as a natural non-synthetic plant pesticide. The neem products have been obtained from several species of neem trees in the family Meliaceae. Array of more than 300 bioactive compounds in the neem tree makes it a unique plant with potential applications in pest and vector management. Botanical pesticides, such as neem, have limited persistence in the environment, and ultraviolet light, temperature, rainfall and other environmental factors can degrade neem. Unlike toxic synthetic insecticides, neem materials do not kill the pest, but incapacitate or neutralize it via cumulative behavioural, physiological, and cytological effects. In spite of high selectivity, neem materials affect more than 400 harmful species including insect pests, phytophagous mites, mites, and ticks affecting man and animals, parasitic protozoans, noxious molluscs, plant parasitic nematodes, pathogenic fungi, and harmful bacteria and fungi. Neem ingredients affect insects in various ways such as repellent, antifeedant, toxic, fecundity and growth regulatory effects. This review presents an overview of recent advances in research on the environmental impact of neem products and their use and effectiveness as a biopesticide.

Ali Çaylı | Emir Hüseyin Kaya
Due to rapidly increasing population and urbanization, agricultural lands are shrinking. However, environmental problems and pollution are constantly increasing. This poses a threat to agricultural production and food access. In order to overcome these threats, the use of fully controlled indoor production systems called plant factory is becoming widespread. The management of plant nutrition and monitor of environmental conditions is very important for production in the plant factory. Plant production is sensitive to environmental conditions. For this reason, it is necessary to make accurate measurements in order to ensure the correct climatic conditions. The high cost of control systems designed for this purpose is a problem for producers. In this study, a mini plant factory prototype and control system are presented which is developed by using open source hardware and software. In addition, the temperature, relative humidity and light measured by the low-cost sensors were compared with the reference devices and the system performance and stability were investigated.

This research was carried out to determine the appropriate sowing density in camelina in Tokat ecological conditions. The study was carried out using Ames 26680 camelina genotype in 2016 and 2017 for two years. In this study, 10, 20, 30 and 40 cm row spacings were used. Plant height (cm), number of branches per, number of capsules per plant, number of seed / capsule, thousand seed weight (g), seed yield (kg/da), oil ratio (%) and oil yield (kg/da) were investigated. According to the results, the seed yields of the two years were significantly different. The highest yields were obtained from 20 cm (132,0 kg/da) in 2016 and from 40 cm row spacing (130,6 kg/da) in 2017. As the average of two years, yields from 20, 30 and 40 cm row spacings did not differ significantly. As the average of two years, the oil rate was 36,2% and the oil yield was 43 kg/da. Thus, it is concluded that in fall sowing under Tokat conditions, camelina can be sown in 20 to 40 cm row spacing using 10 kg seed per hectare.

Citrus reticulata Blanco crude flowers extracts (CFE) at four different concentrations (1, 2, 3 and 4%, v/v) were used as natural milk coagulant instead of rennet to apply for Cheddar cheese making from buffalo milk. The physicochemical properties of Cheddar cheeses were compared with cheese made with 0.002% (v/v) rennet (control cheese). Physicochemical properties of Cheddar cheese showed that cheese made with 1% and 2% of CFE had a crumbly and slightly softer texture/appearance. While cheeses containing 3 and 4% crude flowers extracts had semi-hard texture/appearance of curd similar to rennet added cheese. Protein analysis shows that crude flowers extracts made cheese had significantly higher protein content than control. The Cheddar cheese with 3% and 4% CFE were preferred by panelists instead of 1% and 2% CFE for their taste, texture/appearance and overall acceptability. Conclusively, crude flowers extracts coagulated Cheddar cheese fulfills the compositional requirement with acceptable organoleptic characteristics and at the same time provides nutritional health benefits.
