This study was carried out to determine the influence of different levels of alfalfa meal and the addition of enzyme on performance, carcass and intestinal parameters in growing quails. Japanese quails (n=240), 1 days of age, were divided into 6 dietary treatment groups and the experiment lasted for 5 weeks. In each experiment group there were 4 replicates, and in each replicates there were 10 chicks. Six diets, arranged a factorial design with three alfalfa meal levels (0, 2.5 and 5.0 %) and two levels of added enzyme (0.0 and 1.0 g/kg) were used. The treatments did not effect on the body weight, feed intake and feed conversion ratio. However, relative liver, leg+back, intestine weights and crypt depth were significantly increased, and relative heart and breast weights and villus width decreased by dietary alfalfa meal levels. The addition of enzyme to diets containing alfalfa meal did not affect the performance and carcass parameters, but reduced the intestinal histomorphology parameters in quails. According to the results obtained from the experiment, it can be said that the use of alfalfa meal in growing quail diets did not affect the performance, but the use of alfalfa meal at the level of 2.5% in the diet promotes intestinal development.

Shiitake mushroom (Lentinula edodes (Berk.) Pegler) popular as both edible and medicinal, is one of the most cultivated and consumed mushroom species in the world. Cultivation of this mushroom on different agricultural wastes has been experimented in many studies until today. Nevertheless, agricultural waste trials are going on as agricultural production patterns of the countries are different. In this study, volatile aroma composition of shiitake mushroom produced on different agricultural wastes (wheat stalk, wheat bran, peanut shell, corn cob and vine pruning waste) was compared. Oak sawdust was selected as control because of its common use in literature and substrate materials were mixed at different ratios. In addition, some substrate mixtures were prepared with poplar sawdust. Volatile compounds of the shiitake mushroom were determined by using headspace-solid phase microextraction (HS-SPME) technique combined with Gas Chromatography-Mass Spectrometer (GC-MS). At the end of study, 41 volatile compounds were detected and dimethyl trisulfide, benzaldehyde, dimethyl disulfide, 1-octen-3-ol and 3-octanone were found to be dominant volatile components. Flavour and fragrance of mushrooms are dependent on many volatile aroma compounds and their proportions. While the concentration of eight-carbon components and hydrocarbons was found the highest by using wood straw, amount of sulphur containing compounds and alcohols increased by agricultural wastes in this study. In addition, corn waste positively affected aldehyde compounds.

Due to a better understanding of its positive effects on nutrition and health, consumer demands for sesame seeds and products have increased steadily in recent years. The aim of the study is to determine the total phenolic content belonging to 17 different sesame genotypes (with different seed color) and the antioxidant content by DPPH and ABTS methods. The total amount of phenolic substance varied between 1.99-6.81 mg GA/g, and the highest amount of phenolic content was obtained from the Libya genotype, while the lowest value was obtained from the Gaziantep-Oğuzeli genotype. While antioxidant activity values obtained according to DPPH method varied between 8.23 and 17.50 mg Trolox/g, antioxidant activity values obtained according to ABTS method ranged between 3.62 and 4.18 (mmol Trolox)/g. According to the correlation analysis, it was determined that there was a statistically significant and positive relationship between antioxidant capacities according to total phenolic content, DPPH and ABTS methods. However, no relation was found between the seed color and these properties.

The present study was carried out to evaluate the effect of nitrogen on growth and yield of chili (Capsicum annuum L.) under rooftop conditions. The single factorial experiments were laid out in Randomized Complete Block Design (RCBD) with three replications. Four levels of nitrogen N0: 0 kg N ha-1, N1: 90 kg N ha-1, N2: 110 kg N ha-1 and N3: 130 kg N ha-1 were used in this experiment. Growth and yield contributing parameters significantly influenced by different doses of nitrogenous fertilizers. The dose of N2 gave the highest plant height (80.97 cm) and most of the morphological parameters increased with increasing nitrogen levels up to N2. The treatment N3 gave the highest fruit length (4.93 cm), yield of fruits plant-1 (165.33 gm), average fruit yield plot-1 (0.66 kg), individual fruit weight (1.97 g) and average fruit yield (5.533 kgha-1). Based on the present results, it can be suggested that use of 130 kg N ha-1 increased plant growth and fruit yield of chili in rooftop garden.

The existence of a large amount of seeds in citrus fruits results as a major impediment to customer acceptability, even if the fruits have high organoleptic properties. Irradiation, which mainly reduces seed number of varieties, is a faster way than hybridization. The use of irradiation in citrus breeding programs is now quite widespread with most programs in the major citrus producing countries actively developing new selections. The present study reports the primarily results of gamma irradiation on seed number and fruit quality of Ortanique tangor mutant population. The shoots of scion were irradiated with gamma rays from 60Co at the dose of 50 Gy (gray) in April of 2014. All the treated buds were then immediately budded onto rootstocks and the survival rate was recorded as 60.34%. In order to stabilize the mutation, mV3 plants were developed by re-budding and plants at mV3 generation were transplanted in the orchard in 2017. Within the following year, 68 mV3 plants out of 852 grown in the field bore sufficient amount of fruit and were screened in terms of 19 fruit quality characters such as seed number per fruit, fruit diameter and ripening index. Fruit diameters of mV3 population varied from 56.72 mm to 84.79 mm, and fruit weight ranged between 90.00 g and 287.60 g. The number of seeds per fruit ranged between 0.6 and 13.1 whereas seed number of non-irradiated Ortanique tangor was recorded as 10.7 in the same fruit crop year. In general, fruit characteristics such as fruit weight, fruit height and fruit diameter which describe fruit size of a big part of the population, were similar to Ortanique tangor. According to primarily results, 18 plants have been described as low seeded (≤4). In addition, a cluster analysis was performed by using Euclidean similarity coefficient and similarity index ranged between 29.29% and 93.10% regarding variables related to fruit. The stability of mutations detected is being evaluated and new commercial field trials will be established with the selected materials.

The research was carried out in a 3-floor cage system in the research farm of Tokat Gaziosmanpasa University. 6 chickens were placed in each cage compartment and 5 repetitions were created on each floor. Existing eggs were collected at 9:00 - 13:00 and 16:00 from a total of 90 Atak-S chickens between 24-42 weeks. A total of 1442 eggs were obtained from 90 chickens. To determine the relationship between cage position and laying time, correspondence analysis was applied. SPSS package program was used to analyze the data. According to the results, it was found statistically significant that chickens on different floors lay eggs at different times. According to the results of the correspondence analysis, the first dimension explanation power was 99.7% and the explanation power in the second dimension was 0.3%. When the inertia in terms of lattice layers in the first dimension was examined, it was determined that the explanation power of the first floor was 65.4%, and in the second dimension, the explanation power of the second (56.9%) and third floor (41.8%) was higher. When the variability in terms of egg collection hours in the first dimension was examined, it was determined that the explanatory power for egg collection at 13:00 was 52.8%, and in the second dimension, it was 79.6% for the egg collection at 16:00. As a result, it was determined that the chickens on the first floor lay eggs between 9:00 am and the chickens on the 2nd and 3rd floor between 13:00 and 16:00. Although the eggs vary depending on the ambient temperature, it is known that they are usually collected in the morning hours by the producers. Therefore, it is important to rearrange the frequency of egg collection both economically and in terms of consumer health.

In this study which was carried out during the 2015 summer season in Eskişehir, the flower, pod and seed characters attributed to yield components were investigated in 12 forage pea genotypes. They showed significant differences in terms of agronomic and morphological (flower, pod, and seed) traits. The highest fresh hay yield with 2171 kg/da and plant height with 106.6 cm were obtained from Populasyon-1. Crackerjack had lower values in some flower traits such as, whereas the higher values of pod and seed traits were obtained from cv. Rose. In addition, Population-1 included in the higher value group for standard petal width, keel petal length, calyx tube and teeth lengths, and flower length. Although cluster analysis did not reflect agronomic traits, the clustering resulted in four groups. The first group consisted of Özkaynak 1, 2, and 3 and Taşkent, Töre, and Population-2, which were the standard petal colour violet, light, and dark violet. Population-1 had both violet and white standard petal; however, it was included in the second group together with white-flowered Ulubatlı and Ürünlü according to cluster analysis. While Rose and Gölyazı were in the third group, Crackerjack was in the fourth group alone. There was a highly significant positive correlation between fresh hay yield and both standard petal width and length and flower length. Consequently, a hopeful result for summer growing in Eskişehir condition was obtained from Population-1. It was suggested that some flower characters can be used for pre-selection of yield-related traits in the evaluation of genetic diversity of pea germplasm through morphological trait.

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).

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.

In this study, pectin was extracted by acid extraction method from pomegranate peel. The temperature, time and particle size which affected pectin yield were optimized using response surface method. As a result of optimization, optimum conditions for pectin extraction from pomegranate peel were determined as 468-568 µm for particle size, 82°C for temperature and 47,5 minutes for extraction time. After the extraction at optimum conditions pectin yield was found to be 25,96%. In addition, pectin that was produced had equivalent weight of 488,01 mg, methoxyl content of 5,74%, the degree of esterification of 47,43%and anhydrogalacturonic acid content of 68,64%. The results showed that the obtained pectin was low methoxyl pectin.
