In turkey, one of the most important problem of livestock’s production is insufficiency of quality forage crop, but still few forage species are cultivated. On the other hand, conservation of plant genetic resources has become an important problem in the world today. Indeed, biodiversity is an indispensable element of human life, especially food, and it is estimated that 20% of these resources will extinct by 2030. The aim of study was to determine some quality traits of white sweet clover (Melilotus alba Desr.) collected from natural flora of Bilecik province. In this study, plants were collected at the flowering stage and investigated of 17 genotypes. The determined quality traits of genotypes as fallows; crude protein, ADF, NDF, RFV, K, P, Mg, Ca and Ca/P, and these traits were noted as11.99-21.07%, 27.70-40.53%, 43.31-55.84%, 93.44-147.02, 1.300-2.807%, 0.187-0.310%, 0.127-0.350%, 0.490-1.417% and 2.05-5.92%, respectively. As a result of the study, it has been determined that the quality of the white sweet clover genotypes collected from Bilecik natural flora have been sufficient for animal feeding and have a significant potential for future breeding activities.

The belief that ancient wheat is more beneficial than common wheat has been growing trend in recent years among the consumers. The present study aims to compare bioactive peptide, allergen peptide and toxic peptide generation after gastrointestinal digestion of modern wheat (Triticum aestivum) and ancient wheat, einkorn (Triticum monococcum var. monococcum), using in silico tools. The primary sequences of both kinds of wheat were obtained from BIOPEP-UWM and UniProtKB/Swiss-Prot database. In silico digestion was applied using BIOPEP-UWM online tool. For the simulation of gastrointestinal digestion pepsin (pH 1.3) (EC 3.4.23.1), trypsin (EC 3.4.21.4), and chymotrypsin (EC 3.4.21.1) were selected and analyzed. Homology analysis was performed for each protein sequences using EMBOSS Needle program. Toxic and allergen peptides were predicted using ToxinPred online tool and Allergen FP v.1.0. The results showed that einkorn and common wheat proteins exhibited similar properties including high similarity rate (58.72-87.40%) indicating the percentage of matches between the two sequences and the identical bioactivities for peptides generated after digestion. Most of the bioactive peptides were dipeptides and the majority of them displayed more than one bioactivities including ACE inhibitory, DPP IV inhibitory or antioxidant activity, etc. Allergen peptides generated after in silico digestion were found to be similar for both kinds of wheat. In silico gastric digestion of einkorn and wheat caused toxic peptides production, but they were disappeared after in silico intestinal digestion. In conclusion, although there is a perception related to the Einkorn that is healthier than common wheat, in silico digestion of common wheat and einkorn did not support this perception.

In the study, which is conducted in mountain villages of Mersin province, 99 people selected by simple random sampling method. The data were collected by face to face interviewed. 64.6% of the individuals were male, 35.4% female and 35.4% had a primary school diploma. The average household width was 2.38 and the average age was 50.32. Small ruminant and beekeeping activities are the main source of livelihood for individuals who lives in mountain villages, but also they are benefiting from forest products. As forest products, medicinal aromatic plants such as centaury, thyme, rosehip, mushrooms, blackberries, carob, and straw are used. Men work more intensively in jobs such as wood, timber and resin, which require heavy labour, while products such as centaurs, blackberries and rosehips are collected by women. Individuals' perceptions of forest and forest products do not change according to gender, age and education level. This is because they need the forest and its’ products to maintain their lives. In general, it is determined that the population living in the mountain villages live a life based on forest and forest products. In this context, protection of forest areas in the region is very important both for the prevention of environmental damage and for the people of the region. In addition to individual awareness, support should be provided by the relevant ministries on the use and protection of forests and products. The aim of this study was to identify the use of forest products and opinion about forest who lives in mountain villages of Mersin.

Bu çalışma, farklı mikoriza türleri aşılaması ile birlikte farklı dozlarda kompost ve fosfat kayacı uygulamalarının sorgum bitkisinin gelişimi ve besin elementleri alımına olan etkilerini belirlemek amacıyla yapılmıştır. Denemede kompost dozları 0, 20, 40 g kompost/kg toprak, fosfat kayacı dozları 0, 2, 4 g fosfat kayacı/kg toprak olarak uygulanmış, mikoriza türleri olarak; Funnelformis mosseae, F. caledonius, Claroideoglomus etunicatum, Rhizophagus clarus, doğal ve kokteyl (karışım) kullanılmıştır. Hasat sonunda kök ve kök üstü aksam kuru madde üretimleri, fosfor (P) ve çinko (Zn) konsantrasyonları ve mikorizal kök infeksiyonu analizleri yapılmıştır. Araştırma bulgularına göre, mikoriza aşılaması sorgum bitkisinin kök ve kök üstü aksam kuru madde üretimine, P, Zn ve kök infeksiyonuna fosfat kayacı ve kompost uygulamalarına göre daha fazla oranda etki etmiştir. En etkili mikoriza türü olarak F. caledonius ön plana çıkmaktadır. Kompost uygulamalarında 20 ve 40 g/kg toprak doz uygulamaları etkin bulunur iken, fosfat kayacında ise yetiştirme süresinin kısalığı nedeniyle fosfat kayacının yeterince çözünemediği kanısına varılmıştır.

In this study, optimum harvest times, cluster and berry characteristics of four grape cultivars (Hasandede, Öküzgözü, Boğazkere, and HorozKarası) grown in Mecitözü (Çorum) ecological conditions were determined. In two consecutive years (2017-2018) yield, clusters, berry properties, water-soluble solid content, pH, titratable acidity, maturity index properties were determined. Some biochemical changes in grape varieties were followed during the ripening periods in the second year. The highest yield in both years was obtained from the variety of Horoz Karası (1421.2 and 1504.8 kg/da), while the lowest yield was obtained from Öküzgözü (619.4 and 578.31 kg/da). During the harvest period, the total acidity and pH values must be changed according to years and varieties. The total soluble solids (TSS) and pH values increased with maturation, whereas the total acidity was found to decrease till the last observation date. During the harvest period, all varieties reached optimum harvest maturity in both years.

The basic rule in honeybee (Apis mellifera L.) rearing is to work with qualified queens. Quality queen means strong and healthy colonies. Honey bee colonies are a social community, each managed by a single queen bee. The queen bee is the only female that produces eggs in the colony under normal conditions, and the quality and healthy queen is important for the continuity of the colony. Many factors affect the quality of the queen bee, such as the rearing colony, the age of the transferred larva and the transfer medium, the season, cell emergence weight, spermatheca charged, the characteristics of the starter and finisher hives. In this paper, the issues to be considered in raising a quality queen are emphasized.

Medicinal plants are important natural materials used in the treatment of many diseases. In this study, total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) of endemic Salvia absconditiflora Greuter & Burdet were determined. Plant samples were collected from Nigde and Erzincan (Turkey) provinces. Ethanol (EtOH) extracts of plant samples were extracted. TAS, TOS and OSI values were determined using Rel Assay Diagnostics kits. As a result of the studies, it has been determined that the samples of the plant collected from Nigde have higher TAS, TOS and OSI values. As a result, it has been determined that S. absconditiflora can be used as a potential antioxidant source due to high TAS values.

This study was carried out to determine the levels of retinol, α-tocopherol, cholecalciferol and reproductive hormones (follicle stimulating hormone - FSH, luteinizing hormone - LH, progesterone, estradiol) in the female rats administrated Allium schoenoprasum L. ethanol extract (ASLEE) and acrylamide. The study was performed on thirty-two Wistar albino female rats (200-220 grams). The rats were divided into 4 groups with an equal number. Serum LH values were higher in the ASLEE group compared to the other groups. Control group: No treatment was performed. Acrylamide group: Acrylamide was administrated by gastric gavage at a dose of 25 mg / kg daily. ASLEE group: ASLEE was administrated by gastric gavage at a dose of 200 mg / kg daily. Acrylamide + ASLEE group: Acrylamide was administrated by gastric gavage at a dose of 25 mg / kg daily. Then ASLEE was administered by gastric gavage at a dose of 200 mg / kg per day. Serum FSH and LH values were significantly lower in the acrylamide group compared to the other groups. Serum LH values in the acrylamide + ASLEE group were significantly restored compared to the acrylamide group. Serum estradiol values were partially lower in the acrylamide group compared to other groups, but there was no significant difference between the groups. Serum progesterone values in the acrylamide group were significantly lower than the control group. Serum progesterone values were higher in the acrylamide + ASLEE group compared to the acrylamide group. As a result, the levels of retinol, α-tocopherol, cholecalciferol and reproductive hormones in ASLEE were determined in this study. In addition, when ASLEE was applied with acrylamide, the rate of change in the relevant parameters was determined.

To be about 65% of Turkey's population under 40 years of age requires to increase employment opportunities for young people and them to be sustainable. Young people are moving away from agriculture due to lack of income, life difficulties in the villages and limited social facilities, fragmentation of the lands or too little, and lack of alternative employment opportunities in the countryside. Youths away from agriculture; it causes problems such as aging and decreasing of rural population. For these reasons, it is necessary to determine the tendency of the young people to stay in agriculture, the factors causing them to stay in agriculture or to leave. The aim of this study is to determine the tendency of the young people between the ages of 18-40 who have benefited from the Young Farmer Grant Support in Gaziantep and Şanlıurfa provinces to stay in agriculture and migrate from rural to urban areas. The stratified sampling method was used in the sample selection. In the selected provinces, 72 farmers who benefited from grant support were interviewed and the data were collected through surveys. The data on the socio-demographic characteristics of the enterprises are presented with various descriptive statistics. According to the results of the study, 88.9% of young farmers stated that they would continue agricultural production. 39% of young farmers tend to migrate from rural to urban areas. One of the most important factors in ensuring sustainability in agriculture is the creation of an entrepreneurial young audience. For this reason, policies need to be developed by decision-makers to encourage youth to stay in agriculture.

The aim of this study is to compare the least squares (LS) method that lost its function in the case of multicollinearity in regression methods with Ridge Regression (RR) and Principal Components Regression (PCR) which are bias estimators. For this aim, the effect of some body measurements on body weight (BW), body length (BL), height at withers (HW), height at rump (HR), chest depth (CD), chest girth (CG) and chest width (CW) obtained from 59 Saanen kids at weaning period raised at Research Farm of Tokat Gaziosmanpaşa University. Determination coefficient (R2) and mean square error (MSE) values were used to evaluate the estimation performance of the methods. The multicollinearity between height at withers (HW) and height at rump (HR) which were used to estimate body weight was eliminated by using RR and PCR. When R2 and HKO values of the examined methods are compared; It has been shown that RR method have better results of live weight of Saanen goats.
