In order to gain competitive advantage in national and international markets through globalization, make the competition sustainable, produce products with advanced technologies and innovative activities and make a flexible production in line with changing demand make firms and / or sectors advantageous in global competition. This study aimed at analyzing a competitive analysis of fruit sector through the Diamond Model developed by Michael Eugene Porter in order to demonstrate national and sectoral competitiveness. For this purpose, the current situation of fruit sector, which is an important economic activity in Isparta, was put forward and analyzed its competition level was discussed. The necessary data for the Diamond Model were gathered through face-to-face surveys with 47 large fruit producers and in-depth interviews with the representatives of other related sectors. Although the fruit sector and related sectors have been located close to natural resources and inputs in the neighbourhood in Isparta, an ordinary agglomeration has emerged but it could not be clustered because collaboration culture has not been developed in the sector and intersectoral. This fact decreases the regional competition chance of the sector. However, existence of an easy and continuously communication among all actors in the sector, state supports to sectoral cooperation / organizations, and actors who are compulsory for benefiting these supports in the region should be considered important advantages for a clustering and increasing regional competitiveness power of fruit sector.

In recent years, youth unemployment in Turkey is the effect of economic growth on employment and unemployment. When we search studies for employment and unemployment in the literature, we can’t find many empirical studies for the Turkish economy. In order to contribute about this subject, we try to search the effect of economic growth on youth unemployment for the Turkish economy for the period of 1998-2016 employing Dummy variables. Especially, we found that, increasing effect of economic growth on youth unemployment.

Sour cherry (Prunus cerasus L.) (Rosaceae) is a spring fruits. It is not preferred to be consumed as fresh because it is sour, but it is extremely beneficial for human health. In addition to fresh consumption, it is used in the production of fruit juice, syrup, jam, marmalade, cake and ice cream in the food industry. Sour cherry is grown widely in Tokat and 80-85% of the grown cherries are sold to juice factories. Producers mostly adopt chemical control against pests. In this respect, monitoring pesticide residues on sour cherry is extremely important. This study was carried out to determine the pesticide residue levels in samples taken from sour cherry production areas in Tokat province in 2020. The residue analyses were performed by using QuEChERS method and LC-MS / MS (Liquid Chromatography / Tandem Mass Spectrometer). According to the results, the pesticide residue levels were found below the maximum residue limits (MRL) given in Turkish Food Codex (TFC).

Tuber samples were collected from Kırklareli province on the 10th of August 2020 and they are identified by implementing both traditional methods and molecular phylogenetic analysis using the rDNA sequences including Internal Transcribed Spacer (ITS) and 28S Ribosomal Large Subunit (LSU) regions. By taking into account the high sequence similarity between the collected samples (ANK Akata 7351) and the truffle species Tuber fulgens Quél. the collected specimen was regarded as T. fulgens and the morphological data also consolidated this finding. As a result, T. fulgens was reported for the first time from Turkey. A short description of the newly reported species is given along with its macro and microphotographs, and spore images taken by a scanning electron microscope (SEM). Additionally, ITS and LSU rDNA based evolutionary history of the specimen is provided with phylogenetic trees.

In this study, we aimed to prepare new calixaren embedded mercapto groups supported liquid membranes and to use them in the transport of heavy metals. For this purpose 5,11,17,23-tetra-tert-butyl-25,27-bis(3-thiol-1-oxypropane)-26,28-dihydroxylcalix[4]arene was synthesized. The synthesized calixarene compounds were fully characterized by spectroscopic and the other techniques. The prepared compounds were supported polyamide liquid membranes and obtained calix[4]aren embedded supported liquid membranes (C@PSMs). The characterization of C@PSM was carried out by FTIR, TGA and elemental analysis techniques. Transport experiments were carried out with Pb(II), Cd(II) and Zn(II) as trace metals, to transport from donor phase to accept phase. From the results, it was calculated flux (J) and recovery (RF) values. The affinity (the percentage of metal ion transferred from the source solution) of a PIM towards a range of divalent cations was found to follow the order Zn(II)> Cd(II)> Pb(II).

In developing nations Nigeria inclusive, most of the cereals grown are for human consumption. Conventional feedstuffs use in livestock production especially in poultry enterprise has intensified the competition for available grains. Consequently, the cost of poultry production is jacked up. Since poultry provides most of the animal protein consumed either in the form of meat or egg, exploring tropical vegetables as a route of escape to reducing the cost of feeding will be a great gain in the poultry enterprise. Tropical vegetables especially the African leafy vegetables (ALVs) are economical and highly nutritive possessing good levels of vitamins, minerals, protein and essential amino acids. The mineral constituent of some tropical vegetables as well as their nutritive impact on the performance, meat quality, egg quality in broiler and laying birds as presented in this review paper. Although, the availability of ALVs all year round, its moisture content level and presence of anti-nutrients may tend to limit its usage in poultry feed, adopting irrigation techniques and improved seedlings as well as exploring the processes of enhancing the nutritional value of ALVs to combat anti-nutrients to tolerable levels by the birds make it possible to be considered as good alternative in poultry diets.

This research was carried out in Haymana Research Farm of Ankara University. Three different varieties of wheat were used in the study. These varieties were; Kırgız-95, Kırkpınar-79, and Svevo. The aim of the study was to determine the relationship between soil electrical conductivity values and vegetation index. In the study, EM38, electrical conductivity sensor, and GreenSeeker, vegetation index sensor were used. The obtained values were evaluated statistically, and the relationships between the two parameters were determined. As a result of the research, the relationships between the electrical conductivity of the soil and plant growth index values were found to be negative (R2) as 0.7718 for Kyrgyz-95, 0.7675 for Kırkpınar-79 and 0.7807 for Svevo.

In this study, the relationship between temperature and humidity levels and live weight losses of day-old chicks in broiler pure lines with different feathering rates were investigated. The research material consisted of 3 female pure-lines (A1: slow feathering, A2: fast feathering, A3: slow feathering) and 2 male pure-lines (B1: fast feathering, B2: fast feathering) used in broiler breeding. The hatching chicks were individually numbered, sex-seperated, live weight determined and vaccinations were performed at 26-28°C temperature and 60-65% humidity levels in hatchery. The chickens from different genotypes were placed in cardboard boxes of 68×49×16 cm size with 3 unit and 150 chicks were used in the male-female mixed in 10 chicks in each unit. The chicks were transported in an air-conditioned vehicle for 9 hours between Eskişehir and Samsun, with an average temperature of 28.8°C and a humidity of 40.8%. When the chicks arrived to barn, weight losses are determined individually during transport. The effect of genotypes and feathering rates on live weight loss was found significant. The highest weight loss was determined 1.6 g and 3.8% in B1 and B2 genotypes equally without gender effect. Also, A2 and A3 genotypes were similar too; genotypes with the lowest weight loss of 0,7 g and 0.8 g and 1.6% respectively. Besides, the live weight loss in genotypes with fast feathering was found 1.3 g and 3.1%, which was significantly higher than the slow-feathering (0.9 g and 2.1%). The weight loss fast-feathering male pure-lines is higher than fast-feathering female pure-lines; it is thought that the increase in the metabolic rate due to the selection for live weight increase and faster depletion of the body reserves may be effective in these lines.

The aim of the present study is to assess the effects Fenugreek (Trigonella foenum-graecum, Fabaceae), sunflower (Helianthus annuus, Asteraceae), green cardamom (Elettaria cardamomum, Zingiberaceae) and seed extracts, which they belonged to three different plant families, on common carp (Cyprinus carpio L.) spermatozoa motility parameters and oxidative stress conditions. For this reason, sperm samples treated with seed extracts at the ratios of 0.1%, %0.5, 1%, and 2%, were incubated at 4°C and sampled at 2nd and 48th hours. Among sperm motility parameters, curvilinear velocity (VCL), average path velocity (VAP), straight-line velocity (VSL), straightness STR), linearity (LIN), and wobble (WOB) were determined by computer-assisted sperm analysis (CASA). According to the results, sunflower and green cardamom seed extracts have attenuated motility parameters at all tested concentrations. However, motility parameters measured in %0.5 of fenugreek seed extract were higher than all other groups including the control at 48th hour. Also, TBARS values as an oxidative stress indicator in this group were decreased. 2% of all seed extracts had negative effects on the sperm samples. Particularly, 2% sunflower seed extract caused the higher oxidative stress. These results indicate that fenugreek seed extract is more proper for the maintenance of common carp spermatozoa at 4°C, comparing to those of sunflower and green cardamom.

Main goals of the present study were (1) to initially investigate the nutrient contents and bioactive compounds in the bulb and cloves of garlic, and (2) to study the growth parameter after planting. Garlic bulbs were firstly separated into three categories as pickled, big and small, while the big garlic cloves were also classified into three categories as big, small and central. Secondly, the garlic samples were analyzed before planting for their element profile, proline, soluble protein, free amino acid, β-carotene, lycopene, total phenolic, soluble sugars, SOD and α-amylase activities. Finally, the growth parameters were measured using the cultivated cloves and the pickled bulbs. According to the result, the highest soluble protein, N, phenolic, lycopene and α amylase activity (97.06 mg, 2.58%, 971 mg, 0.368 mg and 38.13 EU, respectively) were recorded in the biggest cloves. The highest proline, amino acid, glucose content (93.84 µmol, 23.54 mg, 230.89 mg, respectively) and K, P, S, Mg, Mn, Fe and Zn (21940 ppm, 7577 ppm, 12200 ppm, 504 ppm, 38.1ppm, 377,7ppm and 44.5 ppm, respectively) were found in the pickled bulb. The maximum level of β-carotene (0.282 mg), Ca, Cl and Sr (11260ppm, 818.7ppm and 47.9 ppm) were determined in the small bulbs. Based on the growth parameters of seedlings, the highest value of shoot and root length (39.12 cm and 24.11 cm respectively), the fresh weight of shoot and root (5.29 g and 4.54 g respectively) and dry weight of shoot and root (1.70 g and 1.24 g respectively) were noted with the big cloves. The results of the current study have indicated that the pickled cloves have higher macro and micro nutrients, proline, amino acid and glucose, while the big cloves of garlic have higher proline, phenolic, N%, lycopene and amylase activity. It can be said that the big cloves showed good value for the five bioactive compounds, but the pickled exhibited good value for the macro and micro element and glucose.
