The aim of this study was to evaluate the activities of the biotransformation enzymes (Glutatyon S-Transferase (GST) and cytochrome P450 (CYP1A1)) and metabolic enzyme (Lactate dehydrogenase-LDH) in the liver of rainbow trout (Oncorhynchus mykiss) after 24 and 48 hour exposure to 0.5, 1.0 and, 2.0 mg l-1 of Congo red (CR). Enzyme activities were determined by using commercial kits with ELISA method. Congo red altered the activities of GST, CYP1A, and LDH enzymes in liver tissue of O. mykiss in a dose-dependent manner. The statistical differences in GST activities among the groups for 24 and 48 h were significant, but, LDH activities were significant for only 24 h. Exposure duration of CR didn’t affect the biochemical response of rainbow trout. Thus, CR exposure changed the biotransformation and metabolic enzymes, and the changes of these enzymes activities may be used as a potential bioindicator of the CR exposure.

Phenolic compounds, organic acids and microbial metabolites as well as high acid content are the main reasons behind the antimicrobial activity of vinegar against various microorganisms. The antimicrobial effect of the vinegar may change depending on raw material, production method and treatment time of the vinegar. In literature, antimicrobial effects of traditionally produced vinegars from different sources such as berry, wood, grape, apple, pomegranate, honey, blueberry, rice and industrially produced vinegars investigated. As a result, vinegars have antimicrobial effect on various gram negative and gram positive microorganisms. The aim of this review is to provide a detailed up-to-date information on the antimicrobial effect of vinegar.

Land banking is one of the systems used in the management and planning of agricultural lands. The aim of the study, to examine the land banking system and the reasons for land banking in Turkey, land banking activities with the establishment stage and examine samples in the world. Land banking in the agricultural sector contributes such as improvement in the land market, guiding the land market for sustainable development and land use planning. In addition, the land banking system is shaped according to the needs of each country and there are four approaches to how the market will have a responsibility and intervene in the market. The prevalence of small-scale enterprises, the scattered and multi-piece of farm lands, which are one of the major problems of Turkish agriculture, hinders the efficient use of resources, hampers the use of technology and threatens food security. Therefore, integrating systems such as land banking into agriculture is thought to contribute to the solution of structural problems.

This trial was realized in the greenhouses of Uludag University Yenisehir Vocational School between 2009 and 2010 to investigate effects of water deficit on yield and quality parameters of pepper during four crop growth stages. In this study, fourteen irrigation treatments in four growth periods (vegetative, flowering, yield formation and ripening) of pepper (Capsicum annuum l. Demre) were constituted and the yield and quality parameters found from these treatments were evaluated. The layout of the experiment was a completely randomized block design with three replications for each of the fourteen irrigation treatments tested. According to the content of the treatments, the irrigation amount water applied to the plants varied between 0 and 744 mm in the first year, and between 0 and 750 mm in the second year. Water consumption of pepper in the first year ranged between 320 and 760 mm and in the second year ranged between 330 and 770 mm. Yield, fruit weight, diameter, length and dry matter ratio were determined statistically significant. In 2009 and 2010 years, the maximum yield were found as 26.2 t ha-1 and 27.8 t ha-1 in V100F100Y100R100 treatments, while the minimum yield were found as 0.2 t ha-1 and 0.3 ha-1 in the V0F0Y0R0 treatments, respectively. Water- yield relationship factors (ky) in 2009 and 2010 years were found as 1.29 and 1.24, respectively. The maximum WUE and IWUE values were obtained from vegetative and ripening periods. Vegetative and ripening periods may be suggested as the maximum efficient irrigation periods for the pepper applied with drip irrigation under unheated greenhouse conditions.

Belediye çöplüğü olarak adlandırılan ve çöplerin düzensiz olarak depolandığı alanlar çevrenin yaşam kalitesini düşürmesinin yanında toprağa ve su kaynaklarına zarar vermektedir. Bu alanların en önemli etkisi depolanan çöplerin içerdiği zararlı maddelerin çevreye yayılması, toprakta birikmesi ve taban suyuna karışmasıdır. Bu çalışmada uzun yıllardır düzensiz çöp depolama alanı olarak kullanılmış olan Çorlu düzensiz çöp depolama alanının, yakınında bulunan tarım alanlarına kirletici etkisi incelenmiştir. Bu amaçla depolama alanı ile Çorlu deresi arasında kalan ve tarım yapılan alandan örneklemeler yapılmıştır. Çöp depolama alanına farklı mesafede 22 noktadan ve 3 farklı derinlikten toplam 66 toprak ve 14 bitki örneği alınmıştır. Toprak ve bitki örneklerinde Magnezum (Mg), Potasyum (K), Kalsiyum (Ca), Fosfor (P), Demir (Fe), Mangan (Mn), Bakır (Cu), Çinko (Zn) analizleri yapılmıştır. Ayrıca verilerin daha kolay anlaşılırlığını sağlamak için, Coğrafi Bilgi Sistemleri (CBS) yardımıyla makro ve mikro elementlerin dağılım haritaları yapılarak, toprak ve bitkide bulunan miktarların daha kolay anlaşılabilirliği sağlanmıştır. Analiz sonuçlarına göre toprakların element içerikleri ile çöp alanı arasında mesafe ile ilgili bir ilişki bulunamamıştır. Araştırma alanının eğimli olması ve bahar yağışlarının topraklarda yıkanmaya neden olması toprakların element konsantrasyonunun değişmesine neden olmuştur. Ayrıca çalışma alanının tekstürü kumlu tından kile kadar değişiklik göstermektedir. Toprak analiz sonuçları kil içeriği yüksek olan noktalarda element konsantrasyonlarının nispeten yüksek olduğunu göstermektedir. Toprakların kirlilik sınıflandırmasına göre tehlikeli metaller içinde yer alan Cu ve Zn sınır değerleri aşmamıştır. Bitkilerde ise Fe hariç Mn, Cu ve Zn içerikleri sınır değerleri aşmamıştır.

Gladiolus is a perennial geophyte, semi-rustice herb and belongs to the Iridaceae family. Gladiolus is an important bulbous ornamental plant. It is used as cut flowers, garden and potted plants. Turkey, which is among the major gene centers of the world and has a special place in plant genetic diversity, has rich genetic resources of geophytes including Gladiolus. However, many plant genetic resources, including Gladiolus are under genetic erosion because of the environmental and other problems and therefore face with the danger of extinction. Turkey has one Gladiolus species in IUCN Red List category. This species is Gladiolus italicus and its Red list category is Least Concern (LC). Gladiolus italicus is distributed in Macaronesia, Mediterranean basin to central Asia. Also introduced and naturalized in California. It naturally grows in many parts of Turkey. The other Gladiolus species that are reported to be under threat in Turkey are; Gladiolus anatolicus, Gladiolus antakiensis, Gladiolus halophilus, Gladiolus humilis, Gladiolus micranthus. In addition to their potential usage as ornamental plants, their usage in phytomedicine due to the medical properties of the modified stems, leaves and in other related industries increases their importance. Therefore, it is very important to protect these genetic resources of Gladiolus.

All feeds used in animal nutrition are classified in various ways, including raw, semi-processed and processed, depending on the additives they contain. Animal feed input, which is generally classified as coarse and mixed feed, constitutes about 30-40% of the total production costs in cattle farms. Therefore, supply-demand elasticity of feed input, input-product price relations and exchange rate changes directly affect the costs, profits and thus sustainability of farms. Additionally, it is necessary to know how the two important activities of the agricultural sector, forage crops production and animal husbandry, affect each other and, if necessary, regulatory measures should be taken. The aim of this study is to determine the effects of cost changes in forage crops production on animal product market. The main data of the study consisted of the time series data of the period 1995-2017 and cross-sectional data obtained from the 107 agricultural farms determined by random sampling method in face-to-face survey method in 2017-2018 production period. Partial equilibrium model used in the study. In the model, diesel and fertilizer prices, which are the most important cost elements in forage crops production; barley, maize and sunflower prices have a statistically significant and positive effect. Partial equilibrium model was used to reveal the effect of cost change in forage crops production on animal product market. Partial balance model results, increasing barley, maize and sunflower prices increase feed prices. Forage crops costs are the highest cost item after purchase of live animal material.
