Recep Gümüş | Nazlı Ercan | Halit İmik
The aim of this study was to determine the effects on some serum parameters of wheat and corn gluten diet, which is also a high protein source. A total of 24 male rats aged 20 days and divided into 3 groups, each containing 8 rats were used in the study. The majority of the protein content in the diet of soybean meal as a Control group; in the diet of wheat gluten as a Wheat group; in the diet of corn gluten as a Corn group were composed. At the end of the study, blood samples taken from all animals were analysed. In the study, serum glucose, TP, urea, creatinine and BUN levels were found to be significantly decreased in Corn group compared to Wheat group. Serum ALT levels were similar with the Control and Wheat groups, but it was found to be significantly decreased in the Corn group. Serum AST levels were significantly lower in the Corn group. Serum GGT levels were significantly lower in both Corn and Wheat groups compared to Control group. Serum Ca and P levels were similar with all groups, whereas Mg levels were significantly decreased in Wheat and Corn groups compared to the Control group. As a result, it can be said that corn gluten added to the diet has more positive effects than wheat gluten in terms of both liver enzyme activities (AST, ALT and GGT) and renal parameters (Urea and BUN).

Suat Dikel | Fırat Sertaç Tellioğlu
In aquaculture, size grading application is made in order to protect against the disadvantages caused by the length difference between fish. Via this activity, large and small individuals separate each other during the feeding period. In this study designed for this purpose, it was aimed to determine whether the large individuals added to the herd had an effect on the growth performance of small individuals in the culture of Oreochromis niloticus♀ x Oreochromis aureus♂ hybrids. In the experiment, 0 age 1-4 g hybrid juvenile which just complete the juvenile period were stocked as 40 fish / m³ in 500 l fibre tanks placed in a greenhouse and cultured for 75 days. The experimental groups were designed as a graded group (G1) containing 1 g small individual, 1 g + 2 g (G2), 1 g +3 g (G3) and 1 g + 4 g (G4). At the end of the study, it was observed that grading did not positively effect on the growth of tilapia hybrids. In contrast, it was revealed that small individuals (18,60 ± 0,33g) in the G2 group, which included large individuals, grew better than small individuals in the other groups. However, the G2 group reached a better FCR (1.39 ± 0.05) than the other groups. The best economic conversion rate was again achieved in the G2 group (11.12 ± 0.75). As a result, it was observed that the culture practice with individuals of different sizes had a positive effect on the development of hybrid tilapia juvenile, especially when juvenile were stocked as 1+2g stocking composition, as a result of well competition can be established and this situation had a positive effect on the production cost.

Enes Fidan | Aytekin Ekincialp
In this study, the responses of 20 different bean genotypes (13 pole and 7 dwarf) to salt (NaCl) stress at 0 mM, 25 mM and 50 mM were investigated. Salt application was performed together with irrigation water in the same time every day during 4 days. In the study, which was prepared according to randomized plot design with 3 replications, the plants were grown in the pots containing peat-perlite in a ratio of 2:1 under climatic conditions of 23±2°C. Root dry matter, root fresh and dry weight and some nutrient contents (Phosphorus-P, Copper-Cu, Zinc-Zn, Manganese-Mn, Iron-Fe and Magnesium-Mg) were investigated in order to determine salinity tolerance in bean genotypes. The data obtained from the study revealed that salt stress responds differently in both genotypes and applications. When the average of applications of 25 mM and 50 mM salt stress was examined, it was found that while root fresh and dry weight, root dry matter (%) and Fe content increased compared to control group, Mn and P content decreased. Among the genotypes exposed to salt stress, while four genotypes [two pole (numbered as 13 and 19) and two dwarf (numbered as 8 and 11)] were determined to be tolerant to salt, 3 genotypes [one pole (numbered as 14) and two dwarf (numbered as 18 and 20)] were evaluated as sensitive.

2020
Murat Atasoy
Protected areas are one the most important nature conservation landscapes and during the last few decades, the importance of natural areas have been considered as a priority for lifestyle preferences of people around the world. Karatepe Aslantaş National Park is one of the examples for these protected areas in Turkey, however; there have been limited studies focusing on the preservation and development of a socioeconomic plan for the aforementioned national park. Therefore, this study aims to develop planning and management priorities of Karatepe Aslantaş National Park and determine tourism potential towards future-oriented conservation. In this regard, a SWOT analysis was performed to develop sustainable planning and design proposals. To determine the historical transformation of a protected area and its surroundings, Land use/land cover-change (LUCC) detection was performed using Landsat 7 ETM and Landsat TIRS/OLI satellites images of the study area for the years 1990 and 2018. The results showed that in 1990, the mixed forest class dominated the study area (2376.6 ha), likewise, it was the most effective land cover class in 2018 (2178.14 ha). Agricultural land with natural vegetation class occupied the second largest area for both 1990 and 2018 with 1264.72 ha and 880.13 ha, respectively. A marked decrease was found for the transitional woodland/shrubs cover (565.8 ha in 1990 to 330.35 ha in 2018). Among the all land use classes, the highest percentage of change was found for broad-leaved forest cover at 200% between 1990 and 2018, while the lowest percentage of change occurred to water bodies with 8.82% in the same time frame. Regarding the findings, management proposals have been developed to conserve the protected area considering its tourism potential and archeological heritage values. Therefore, it is recommended that the lack of planning and management strategies needs to be fulfilled as a legal commitment by government agencies.

Muhammad Atif Sikandar | Zaigham Hassan | Abdul Basit | Raees Khan | Fethi Ahmet Ozdemir
Labeo rohita and Cirrhinus mrigala are the two Indian major carps and chief components of polyculture system in the local population. Proximate body composition is the analysis of water, fat, protein and ash contents of fish. Values are vary considerably within and between species, size, sexual condition, feeding season and physical activity. The percentage of water is a good indicator of its relative contents of energy, proteins and lipids. Determination of some proximate profiles such as protein content, lipid, ash and other nutrients is often necessary to ensure that they are within the range of dietary requirement and commercial specifications. Based on this background the present study was aimed to evaluate the nutritional value of some major craps (Labeo rohita and Cirrhinus mrigala) fishes of Peshawar Carp Hatchery and training centre Sherabad. The proximate composition of Labeo rohita and Cirrhinus mrigala samples were determined and data was evaluated statistically by performing t-test through Sigma Plot and graphs were made by using Graph Pad Prism. The average value of crude protein for Cirrhinus mrigala was found higher than Labeo rohita (51.7% and 39.04%) similarly the water contents were also found higher in Cirrhinus mrigala than Labeo rohita (75.88% and 73.95%). The average value of dry matter and muscle fats contents were lowered in Cirrhinus mrigala than Labeo rohita (24.11% and 26.04%) and (13.00% and 13.45%) respectively. However, the ash contents were similar in both of experimental species (23.91% and 23.93%). From these results, it is concluded that both Cirrhinus mrigala than Labeo rohita are very proteineous and have low fats contents so it is very good for the health of consumers. Further research is recommended on the other parameters and miss rays of this work.

Salgam (Şalgam, shalgam) is our conventional fermented purple carrot beverage. Purple carrot (Daucus carota) is the basic raw material, and other raw materials used in the production are sourdough/ bakers’ yeast, salt (rock), bulgur flour and/or turnip (Brassica rapa L.). There are two fermentations that occur due to microorganisms (lactic-acid bacteria and yeast) that are effective during production; primarily lactic-acid fermentation and ethyl alcohol fermentation. It is very popular in our country, especially southerly cities of Turkey. Although shalgam is mostly produced and consumed in Mersin/İcel, Osmaniye, Hatay-Antakya and Kahramanmaras cities, the most known and loved city is the Adana. Lately, it has begun to be consumed almost every parts of Turkey. In addition, it is sold in the cities where the densities of the Turks in Europe. The aim of this review article is to give information about the production methods of salgam, scientific studies and recent trends, problems related to salgam and solutions.

Tigist Beyene | Meseret Chimdessa Egigu
Striga is a parasitic weed causing remarkable yield lose in Sorghum bicolor. In this study, phytotoxicity of leaf and flower extracts of Striga hermonthica were investigated on three sorghum varieties under laboratory conditions. Before allelopathic bioassay, total phenolics, alkaloids and terpenoids were quantified in the extracts. For allelopathic bioassay, 5 and 10% (w/v) aqueous extracts were prepared by reconstituting dried crude extracts of leaf and flower of S. hermonthica in distilled water. Varieties of sorghum named Muyra 1 (M1), Muyra 2 (M2) and Fendishe (Fe) were treated with equal amounts of 5 and 10% (w/v) extracts in Petri dishes lined with Whatman no.1 filter paper. The control treatment received distilled water and treatments were laid out in a completely randomized design with three replications. Germination parameters were monitored for 15 days and General linear model was used to analyze data. Results showed that both leaf and flower of S. hermonthica produce phenolics, alkaloids and terpenoids. Values of total phenolics and total alkaloids did not show significant variation, whereas total terpenoid was significantly higher in flower than leaf. Percent germination, shoot and root lengths as well as their dry weights were significantly affected by extract concentration, sorghum variety and their interactions. Compared to control, percent germination and seedling growth were highly reduced at 5% w/v extract concentration and completely inhibited at 10% w/v extract concentration. Varieties were not differentially affected by leaf extracts, but M1 and M2 appeared to be more affected than Fe by flower extract. The result also showed that root growth was more affected by extracts than shoot growth. Overall, this study for the first time revealed that S. hermonthica reduces yield of S. bicolor not only due to parasitism, but also through its negative allelopathic effect on seed germination and early seedling growth.

2020
Nafiz Çeliktaş | Ömer Konuşkan
The application of near-infrared reflectance spectroscopy (NIRS) and multivariate analysis for determining the seed germination rate of corn genotypes was assessed. Seed samples about 90 gr belong to commercial and local corn varieties at various ages were scanned with FT-NIRS on the reflectance mode from 1000 to 2500 nm wavelength. Filter paper technique showed the seed germination rates varied between 18-100% depending on the genotypes after 7 days at ±25°C. Partial least squares regression (PLSR) was applied to the reference values corresponding to the spectra. The best statistical results obtained from the pre-treatment combinations of Smooth Savitzky-Golay 9 Points (sg9), MSC full and normalization to unit length (nle). The regression coefficient of calibration (R2C) and prediction (R2P) of the created NIRS calibration via chemometric software NIRCal are realized 0.97 and 0.98 respectively for the property of corn germination rate. The standard error of both calibration (SEC) and prediction (SEP) were almost overlapping (4.17%, 4.61% respectively). The prediction accuracy of the final NIRS model was quite reasonable with the acceptable root mean standard error of prediction (RMSEP) as 8.88%. According to the residual predictive deviation (RPD) index (4.18), the accuracy of the NIRS model regarded as in the best category. Therefore, the NIRS model developed here is sufficient to predict the corn seed germination rate very fast and non-destructively without using any regents.

The study aims to investigate the effects of changes in body weight of Japanese quails (Coturnix coturnix japanica) on some external and internal quality characteristics of their eggs and the correlations between them. In the experiment, totally 30 female quails raised in individual cages and 180 eggs obtained from them were utilized. According to the body weight, 30 quails were divided into 5 different groups and body weight averages were 238.0, 216.0, 202.3, 191.3 and 174.0 g for 1st, 2nd, 3rd, 4th and 5th groups, respectively. The examined eggs were individually collected from the quails and evaluated under live weight groups of quails. According to the results, egg weight, shell weight, shell thickness, shell ratio, albumen weight, albumen ratio, yolk weight, yolk diameter, and yolk ratio were significantly affected from body weight. There were found significant positive correlations of live weight with egg weight, albumen weight and yolk weight (respectively, 0.28, 0.24, and 0.25) and significant positive correlations with shape index and shell weight (respectively, 0.17 and 0.15).
