This study was conducted to determine tolerance levels of different radish varieties (white, black, red, little red radish) under salt stress conditions and to evaluate the effectiveness of exogenous salicylic acid (SA) application on germination and vegetative development. For this purpose; germination percentage (%), germination time (day), germination index calculated, and then number of leaves, shoot length (cm), root length (cm), leaf width (cm), leaf length (cm), stem diameter (mm), plant fresh and dry weights (g) were measured. Radish seeds were germinated at control, 100 mM, 150 mM and 200 mM salt concentrations. Salt stress did not inhibit germination at a high level but negatively affected the vegetative growth of plants. According to the results of the statistical analysis of the data obtained, 150 mM was determined as the threshold value. Then, SA was applied to seeds treated with 150 mM salt concentration at different doses (0.25, 0.50, 0.75, 1.00 mM). SA had a positive effect on germination in saline conditions in general and it was concluded that 0.50 mM SA could be applied for germination percentages in all cultivars. However, 1 mM SA inhibited the germination of big red and little red radish cultivars, causing sudden and severe germination losses (10%, 8%, respectively). The effects of SA on vegetative growth parameters differed by cultivar and it was found to be inhibitory in terms of vegetative growth characteristics of white radish cultivar. On the other hand, 0.50 mM SA in black and big red, 0.75 mM SA in little red cultivar gave promoting results for vegetative growth.

According to FAOSTAT 2017 data, Turkey located ranks second after China in terms of world honey production and ranks third in terms of the number of colonies. According to Turkish Statistical Institute (TURKSTAT) 2018 data, Turkey had 7.904.502 colonies and total honey production of 107.920 tons while the average honey yield was calculated 13.7 kg per colony. It is economically important that informing to beekeepers and policymakers the expected change in the number of colonies and honey yield in the next years. This study aims to estimate the production values for the next 5 years by using the number of colonies and honey yields of the past years. For this purpose, the next five years (2019-2023) forecast has been made by using data from the last 50 years (1969-2018). ARIMA (1,1,0) first-degree autoregressive time series model was used for the number of colonies and honey yields from the data obtained from TURKSTAT and FAOSTAT. SPSS package program was used for forecasting. According to the results, compared to 2018 an increase of 1.3% and 7.4% is expected in the number of colonies between 2019 and 2023. In addition, the honey yield is expected to increase between 2.77% and 3.12% compared to 2018. It seems that increasing the number of colonies and expecting a less increase in honey yield per colony will increase the production costs in the next years. Hence, consumers will consume honey and honeybee products at a higher price. It can be suggested that, beekeepers should take care about increasing the number of colonies as well as increase the honey yield per colony to beekeeping economy, consumers and the economy of the country.

Kohlrabi, which has increased production in our country in recent years, is a vegetable with high water consumption. The aim of this study was to determine the effects of different irrigation levels on plant and tuber growth and determine the appropriate irrigation level. In this study, vegetative growth and some tuber quality parameters of two different kohlrabi cultivars (Korist F1, Kolibri F1) at 4 different irrigation levels (I100 I75, I50, I25) were investigated. The experiment was carried out in unheated greenhouse as a pot experiment in April-June with three replicates and 10 plants per replicate. At the end of the experiment; number of leaves, leaf width (mm), leaf length (mm), tuber diameter (cm), tuber height (cm), tuber weight (g), tuber pH, total soluble solid content of the tuber and chlorophyll index were measured. The growth curves of the tubers were drawn and potassium (K), phosphorus (P) and sodium (Na) contents of the tubers were determined. In Kolibri F1, the highest tuber weight was obtained from the I75 irrigated plants with an average of 369.59 g. In Korist F1, the highest tuber weight was obtained from I100 applied plants with an average of 362.25 g. Especially in terms of tuber development, I100 has provided better results in water deficiency application. However, according to the results of the analysis, there was no statistically significant difference between I100 and I75 irrigation levels. It was determined that I75 irrigation level could be applied for kohlrabi cultivars in April-June cultivation period in Antalya conditions.

The studies on phage applications that provide successful results in biocontrol of foodborne pathogens and offer an environmentally friendly approach have been increasing today. Phages are viruses that can infect and kill the specific target bacterial cell. Salmonella is one of the most important pathogenic microorganisms that leading causes of food-borne illnesses called salmonellosis. Meat products especially chicken meat, fresh eggs, dairy products, ready-to-eat foods, seafood products and all kinds of contaminated food can be cause of salmonellosis. In this review, the phage application studies to control of Salmonella in food systems were summarized taking into account the research studied in recent years.

Dairy desserts, which have an important place in Turkish cuisine, are mild, more digestible and have high nutritional value than dough and syrup desserts. In recent years, studies for developing these products have increased due to the increase in consumer demand for low and zero fat products for many different reasons such as nutrition, health and weight control. However, the reduction of fat in food products often leads to undesirable changes in the structural properties of foods, which affects consumer preference. Fat in the formulation of such products, affects the appearance, texture, mouthfeel, and especially flavor. To eliminate the problems associated with the reduction of fat content in foods, whey protein-pectin complexes, λ-carrageenan, κ-carrageenan, short and long chain inulin mixtures, starch substitutes are generally used. Changes in fat content of dairy desserts with the use of substitutes affect color, rheology, texture, sensory perception, aroma release and perception. Milk fat content is effective on sensory detection, in vivo flavor and flavor release in semi-solid dairy desserts. The milk fat content (whole-fat, low-fat or non-fat) used in the production of dairy dessert affects the rheological and sensory properties of the product, the taste intensity perceived in the mouth, flavor release, flow behavior, flavor and viscoelastic properties. According to the reviewed literature, in dairy desserts with reduced fat content, the thickener type and concentration (starch, κ-carrageenan, carboxymethyl cellulose) have been determined to cause perceptible changes in the product’s color, flavor and texture, and may alter the physical and structural properties of the product. In this review, it was aimed to examine the aroma release and rheological properties of dairy desserts with reduced fat content by using fat substitutes.

The maximum length, weight, and age information of organisms in an ecosystem, moreover, the first records of migrated exotic species are essential in terms of the basis for the studies on population dynamics, stock assessment, and biological activities. Therefore, the recording of such data may be necessary for scientific databases and new related studies. The Blackspot seabream (Red seabream - Pagellus bogaraveo), which belongs to the Sparidae family, is an important seafood which is marketed fresh and frozen around the Mediterranean and the Aegean seas. Nowadays, this species has high prices depending on market demands in domestic markets as a result of overfishing and is also cultured in northern Spain. It is classified as “Near Threatened Species” in the red list due to its decreasing population trend by the IUCN. A single specimen of the Blackspot seabream with 30.7 cm in total length and 390.00 g in total weight, which was angled in the Saros Bay with a handline by a fisherman on February 08, 2019, was obtained from a fishmonger in Çanakkale. Even though there are bigger individuals in the North-east Atlantic probably depending on polar and/or deep-sea gigantism, the mentioned measurement is the proven maximum total length of this species for the Aegean Sea up to the time.

Present review was performed in order to understand the influence of photoperiod and light intensity on Coturnix japonica. Different literatures were reviewed regarding egg production, behaviour, body weight, feed intake, feed conversion ratio, carcass weight, egg quality with respect to photoperiods and intensities. It was noticed from the reviewed studies that light intensity of 80 and 20 luxes for 8 hours during growing period and 240 and 60 luxes for 16 hours during laying period results 194.85±4.46, 191.42±2.87 feed intake, 201.00±13.82, 210±15.1 weekly weight gain. The better feed conversion ratio remains (1.03) with light intensity of 80 and 20 luxes for 8 hours during growing period. Carcass weight remains as 98.33±8.33 and 99.56±5.44, dressing percentage 50.46% and 52.01%, egg production percent 50.11 and 48.81, egg length 32.15±0.54 and 32.12±0.35, egg width 24.87±0.22 and 23.75±0.31, egg weight 9±0.44 and 9±0.54, 11.2±0.73 when light intensity of 80 and 20 luxes for 8 hours during growing period and 240 and 60 luxes for 16 hours during laying period is provided. In conclusion Coturnix japonica raised on 80 luxes for 08 hours light intensity during growing period and 240 luxes for 16 hours light intensity in laying period results better FCR and feed intake in cage system. While Coturnix japonica reared with 5 luxes for 16 hours photoperiod during growing period and 15 luxes for 20 hours photoperiod in laying period demonstrate better egg production and behaviour.

The aim of this study is to investigate; the effects of organic and inorganic fertilizer applications on dry matter yield of different plant parts and microelement content of grain in two different buckwheat varieties. While main plots were formed by Aktaş and Güneş buckwheat varieties, sub plots were formed by 5 different fertilizer types (Control, Urea and Worm, Chicken, Cattle manure used as an organic fertilizers) in the experiment. Buckwheat cultivar were cultivated in April 2019 and harvested in July 2019. After harvesting, different buckwheat parts (root, shoot and grain) were determined for micro element content (Cu, Mn, Fe and Zn) with the Atomic Absorption Spectroscopy. Findings results shown that there are statistically significant differences in terms of grain yield as fertilizer applications, cultivars and cultivar fertilizer interactions. While the best results for the Cukurova region were obtained from Güneş cultivar (102.20 kg da-1) as a cultivar, the best results were obtained from the application of Urea (138.1 kg da-1) as a fertilizer application. Although there is no statistically significant difference between the cultivars in terms of grain microelement content, it was determined that there is a statistical difference between the average values of fertilizer applications as Cu, Fe and Mn content. The best results were obtained from urea application on micronutrients in Cu (35.38 mg kg-1), Fe (207.30 mg kg-1) and Mn (37.22 mg kg-1). As a result, the best type of fertilizer in the Cukurova Region is the Güneş cultivar, while the best fertilizer application is urea, which is an inorganic fertilizer. Organic fertilizer applications are not important, but the best results were obtained from cattle manure as organic fertilizer.

Global climate change is seen as a process that will directly or indirectly affect living things and ecosystems all over the world. In this process, determining the changes in climate parameters and climate types in advance is of great importance in terms of the measures that can be taken and the preparation for the process. In this study, it is aimed to determine the changes that may be caused by global climate change in some climate parameters and climate types in Mersin, which is one of the important cities of our country. Within the scope of the study, the current status of temperature, precipitation and climate types (according to De Martone and Emberger climate classification) and RCP 4.5 and RCP 8.5. It is aimed to compare the possible situations in 2050 and 2070 in the light of scenarios. The results of the study show that temperature, precipitation and climate types will change significantly throughout Mersin province. Today, the temperature varying between -0.4°C and 19°C will change between 4.9°C and 24°C throughout the province in 2070 according to the RCP 8.5 scenario, that is, there will be an increase of around 5°C in the temperature change interval, the precipitation regime will change, Climate types are predicted to shift towards arid climates. This situation shows that climate factors, one of the most important planning criteria, will change significantly in landscape planning studies. Since landscape planning studies continue their effects for many years, it is recommended to take this into consideration in order to make a healthy planning. The results of this study should be used in the planning studies for Mersin province.

Plant growth-promoting rhizobacteria (PGPR) is a beneficial group of free-living soil bacteria that colonize the rhizosphere and are helpful in root growth and development. PGPR plays an important role in plant growth through the production of phytohormones, solubilization of inorganic phosphate, increased iron nutrition via iron-chelating siderophores and volatile compounds that affect the plant metabolism and signalling pathways. Additionally, PGPR shows synergistic and antagonistic interactions with rhizosphere microorganisms and soil which indirectly improve and enhance plant growth rate. Various environmental factors affect the PGPR growth and proliferation in the plants. There are several shortcomings and limitation in the PGPR research which can be addressed through the use of modern approaches and techniques by exploring multidisciplinary research which combines applications in microbiology, biotechnology, nanotechnology, agro-biotechnology, and chemical engineering. Furthermore, PGPR is also known to reduce the emission of greenhouse gases (GHGs), carbon footprint, and also increase the nutrient-use efficiency. Here we describe the importance of PGPR in sustainable agriculture and their role in plant growth and development.
