Heavy metal pollution is a significant environmental problem with negative potential impacts on agriculture and human health. In this study, calluses were obtained by using in vitro germinated hypocotyl explants of pepper seedlings and cell suspensions were prepared from these calluses. The effect of silver nitrate (AgNO3) solution added in different concentrations and times to cell suspension cultures of pepper on total protein and total phenolic compound amounts, superoxide dismutase and peroxidase enzyme activities were analysed. Total protein and total phenolic amounts, superoxide dismutase and peroxidase enzyme activities were detected by spectrophotometric methods. When the effects of silver metal on pepper plant were examined, it was determined that silver metal reduced the total protein and phenolic content in the pepper plant cells and especially at higher concentration, in the first 24 hour period, antioxidant enzyme activities increased.

Manuscripts, containing thousands of years of information and experiences about the treatment of diseases of other animal species, mostly horses, are known by different names such as baitarname, esbname, haylname and bazname. These authentic works, which were also established during the Islamic Civilization period, also bear the traces of different civilizations such as Ancient Egypt, Ancient India and Ancient Greek. With this study, it was aimed to shed light on the evaluation of these manuscripts which have thousands of years of knowledge in terms of treatment and preventive medicine in organic animal production. The main material of the work is originated of a manuscript work conducted as a doctoral thesis and of information on the subject. In addition, books, theses, researches and compilation studies that can be reached within the scope of the subject and which were studied before were also evaluated. In these study, it is observed that the use of herbal, animal and mineral resources as medicines in the treatment, as well as the applications of phlebotomization and cauterization are among the treatment methods. Increased pharmacological, toxicological and clinical trials on herbal, animal and mineral drugs, which are accepted as a complementary role even if they are not alternative, could be a valuable source of organic animal production for which artificial drug use is prohibited or restricted.

Etlik piliç yetiştiriciliğinde en uygun yetiştirme sistemi yerde yetiştiricilik olduğundan altlık materyali büyük önem kazanmaktadır. Etlik piliç üretiminde sağlanan gelişmeye bağlı olarak altlığa olan talep de artış göstermektedir. Altlık materyali olarak genelde saman, kaba odun yongası ve hızar talaşı yaygın olarak kullanılmaktadır. Bunlarla birlikte altlık materyali olarak buğday, arpa, çavdar, yulaf, ayçiçeği, çeltik, fındık, mısır, soya, fıstık, pamuk, şekerkamışı gibi malzemeler saf veya karıştırılarak kullanılmaktadır. Altlığın kalitesini altlığın nemi, pH'si, amonyum nitrat içeriği, kekleşme düzeyi ve su tutma kapasitesi belirlemektedir. İdeal altlığın nem oranı %20–25, pH değeri 8–10 arasında olmalı ve amonyak miktarı ise 25 ppm’i geçmemelidir. Altlık kalınlığı, altlığın türüne göre 2-10 cm arasında değişmekte, parça büyüklüğü de 0.6 cm’yi geçmemelidir. Altlık neminin artması pH düzeyini, NH3 konsantrasyonunu ve kekleşmeyi arttırır. Altlık materyalinin türü etlik piliçlerin performansı, refahı, sağlığı, davranışı ve ürün kalitesi üzerine etkili olmaktadır. Ayrıca bu materyallerin karkas kusurları, ayak-bacak problemleri, göğüste su toplanması, yaşama gücünde düşme, altlık nemi nedeniyle mikroorganizma gelişiminde artış, kümeslerde gaz ve toz oluşumunun artması gibi olumsuz etkileri bulunmaktadır. Bu olumsuz etkiler entansif işletmelerde büyük ekonomik kayıplara neden olmaktadır. Bu nedenle etlik piliç yetiştiriciliğinde altlık materyalinin kalitesi ve çeşidi çok önemlidir.

Vermicompost products have gained a great importance in plant nutrition over the years. They are reported to have plant growth promoting effects both in horticulture and field crops. The nutritional value and chemical properties of vermicomposts highly depend on the feedstock used in their production. The aim of this study was to evaluate vermicompost manure, derived from the mixture of cattle manure and kitchen scraps, on seed germination and growth of tomato seedlings (Lycopersicon lycopersicum Mill.). Four solid vermicompost amendment rates of 0, 10, 20, and 30% were applied in plastic trays. Vermicompost application delayed and reduced seed emergence in all application rates, while in general, vermicompost substitution promoted growth tomato seedlings up to 20% of application rate. The results showed that vermicompost substitutions greater than 20% had adverse effects on seedling emergence and seedling growth parameters, which was attributed to high EC of vermicompost induced by cattle manure. Results suggest that both physical and chemical properties of the feedstock used for vermicompost production should be taken into consideration in order to sustain high vermicompost quality to ensure targeted plant growth for horticultural and agricultural purposes.

The objective of this study was to investigate the nutrient content, phytonutrient composition, physicochemical properties, alpha amylase and alpha glucosidase inhibition activity and antioxidant activity of the brown algae Stoechospermum marginatum collected from Gulf of Mannar, Tamil Nadu, India in pre monsoon season (June- September, 2015). Six and eight hours of ethanol and aqueous extract of Stoechospermum marginatum were used for phytonutrient screening, alpha amylase, alpha glucosidase inhibition activity and antioxidant activity. From the results of the study it is understood that Stoechospermum marginatum contain a high amount of carbohydrate, protein, crude fiber and phytonutrients like tannin, flavonoid, saponin, alkaloid, terpenoids, steroid and total phenolic content. The physicochemical properties namely Water absorption and Swelling power were very promising. Alpha amylase and alpha glucosidase inhibition activity was recorded to be high in both aqueous and ethanol extracts of eight hour extraction than in extracts taken from six hours extraction. Antioxidant activity was detected using DPPH, FRAP, beta carotene scavenging and H2O2 assay and found to have a high radical scavenging activity. Stoechospermum marginatum possess a valuable amount of total phenolic content and other phytonutrients and physicochemical properties, it may the reason for the potential inhibition of alpha amylase, alpha glucosidase and antioxidant activity. It is concluded from the study that the brown algae may be incorporated into foods to enhance their nutritional and therapeutic value.

Alkali grass grows in waterlogged, saline and alaline soils. The main problem in these soils is minerals at toxic level. The toxic ions are chloride, sodium and boron. A number of techniques have been investigated for removing toxic metals from the soil. Today, the cost-effective and environmentally technique is phytoremediation, using hyperaccumulator plants. Alkali grass (Puccinellia ciliata Bor) is suggested as a hyperaccumulator plant by the combination of more favourable characteristics with salt and waterlogging tolerance, high biomass value and convincing nutritive value for adverse environmental conditions. For this reason, we collected alkali grass and soil samples from five different locations in Aydın-Muğla highway, Turanlar and Sınırteke villages in Germencik-Aydın. In the soil analysis, we observed that K accumulation varies between root, shoot and panicle at least whereas Na and B shows more variation on whole plant portions among locations. Intense aerenchyma development on the root tips of Puccinellia plant was observed and it is determined as radial lysogenic aerenchyma formation. Average plant height and dry matter values were between 47.2-74.4 cm and 15.61-80.85 g/plant according to locations. The highest plant height value was obtained from the first location whereas the highest dry matter yield was detected in the fifth location. In conclusion, plants from fifth location can be regarded as fodder plants in these areas. Our results indicated that alkali grass can be effective for phytoextraction of sodium and boron from contaminated sites.

RASFF (Rapid Alert System for Food and Feed) is an international system, that provides the rapid information exchange between European Union countries towards risks about food and feed topics, takes the required precautions and thus aims to maintain the food and feed safety. The weekly reports sent by member countries, are presented on web site and the member countries are informed in case of a risk when the product is introduced in the market. The current work includes the notifications originated from our country that took place in rapid alert system reports between years 2009-2016. The data obtained from the system, were classified according to product and hazard groups and the product-hazard relations were evaluated for each year by taking the notification types into consideration. According to the assessments, the main problem about European Union exports of our country is the high aflatoxin level of the products. This problem is mainly observed in fruits-vegetables, nuts and seeds. Pesticide residues and pathogenic microorganisms are the other important hazard groups which cause problems for exports of our country. The results obtained from the current work are critically important for determination of the basic problems met in food export of our country and to capture attention to precautions which should be taken against those problems.
