In this study, it was aimed to determine the ways of supplying breeding animals for sheep enterprises in Ordu. In the research, enterprises with a minimum size of 80 heads have been taken into consideration. Random selection method was used in determining the enterprises and face-to-face surveys were conducted in 86 enterprises. 37.21% of the enterprise owners met their breeding coach needs from their own enterprises, while 33.72% met from their own enterprise + neighboring enterprises. Moreover, it was determined that 52.33% of the enterprise owners met their breeding female animal needs from their own enterprise, whereas 22.08% and 12.79% met from their own enterprise + neighboring enterprise and from their own enterprise + state enterprise, respectively. According to the results, 58.14% of breeders (50 enterprises) keep breeding female animals for more than 5 years in the herd and 41.86% of breeders (36 enterprises) keep them between 3-5 years. Breeding male animals are kept in the herd for more than 5 years in 47.67% of enterprises (41 enterprises) and for 3-5 years in 41.86% of enterprises (36 enterprises). In only 10.47% of enterprises, breeding male animals are used in the herd as breeding for less than 3 years.

The aim of this study was to determine effects of different dietary rosemary essential oil levels on growth performance, carcass traits and haematological values of breeder chukar partridge. Eighty (60 females and 20 males), 32-week-old breeder chukar partridge were randomly divided in five treatments, with four replicate pens with 4 birds each. Five experimental diets were formulated according to rosemary essential oil inclusion rates 0 mg/kg, 24 mg/kg, 48 mg/kg, 72 mg/kg and 96 mg/kg, respectively. The experiment lasted for 8 weeks. The chukar partridges had free access to ad libitum feed and water. At the end of the trial, 1 male and 1 female partridge were slaughtered for blood analysis. The obtained results showed that there was no significant difference in feed intake, body weight gain between the control and treatment groups. Dietary rosemary essential oil supplementation did not affect blood serum glucose, urea, triglyceride, total cholesterol, HDL-C and LDL-C levels in breeder Chukar partridges. It could be concluded that supplementing rosemary essential oil into Chukar partridges diet show no negative effect on growth performance.

The aim of this study is to screen the recombinant inbred lines (RILs) carrying rye translocation for the semi-dwarf (Rht), photoperiod (Ppd) and vernalization (Vrn) genes. Recombinant inbred lines were obtained by hybridization of bread wheat varieties Tosunbey and Tahirova-2000. Only the lines carrying 1BL.1RS rye translocation from population were used in the study. Parents and all of RILs were found to have Rht-B1a, which is a semi-dwarf allele, and Ppd-D1a allele, which is not susceptible to photoperiod. The vernalization alleles (Vrn-A1, Vrn-B1 and Vrn-D1) in the lines were also determined. It was determined that both parents and all the RILs had vrn-A1 allele, and not Vrn-A1c allele. It was determined that 151 of RILs contained vrn-B1 allele and 154 of them contained Vrn-B1 allele, while 131 of RILs had vrn-D1 allele and 174 of them had Vrn-D1 allele. In addition, molecular screening were carried out for waxy alleles (Wx-A1, Wx-B1 and Wx-D1) which were effective on flour swelling, water holding capacity and shelf life of bread wheat. As a result of the molecular data it was found that 141 of RILs carry all three alleles and named as “normal amylose wheat” and 164 of them had only Wx-A1 and Wx-D1 alleles, as known “low amylose wheat”. The results indicated that the population used in the research could be the subject of some researches, especially drought tolerance, and RILs could be used to develop genetic material carrying rye translocation for wheat breeding programs.

The aim of this research was to determine the structural characteristics of the grapevine sapling producing enterprises and to reveal the problems. The main material of study are data were obtained from questionnaire study. In the study, face-to-face interviews were conducted with 12 enterprises which are members of Sapling Producers Sub-Union (SPSU). During the research period, there were 33 SPSU members, but the majority of these enterprises were small-sized and engaged in the purchase and sale without production. In the research, it was tried to be interviewed with all of the large capacity, both production and sales, and 12 of 33 enterprises were interviewed. The interviewed enterprises hold a large part of the grapevine sapling market. The obtained data were evaluated and interpreted by means of percentage distribution tables, average, maximum and minimum calculations. According to the results of the research, enterprises have been producing grapevine saplings on average at the commercial level for 12 years. All of the interviewed enterprises produce bare-rooted saplings. In addition, potted (58.33%) and American grapevine (25%) saplings also are produced. Grafted sapling yield rates of enterprises have been determined as 45% in own root saplings and 72% in potted sapling. 67% of the producers reported that they have problems in sapling marketing and carrying and storing saplings is a significant problem at this stage. The producers demanded that measures to prevent the informal production from authorities.

This study was carried out to evaluate the socio-economic structure and organic farming activities of grape producers in Besni. A face-to-face survey was conducted with producers producing organic grapes. Data were obtained by interviewing a total of 50 producers. The number of organic products grown between 2005 and 2018 increased from 205 to 213 in Turkey. The number of producers engaged in cultivation in this area has increased more than 5 times compared to 2005. It reached nearly 80.000 in 2018. The area of organic vegetable production increased from 203.811 to 626.884 hectares in Turkey. While the production area increased 2.5 times, the production amount increased almost 4 times. Today, a variety of products in organic vegetable production, planting area, the number of farmers has increased in Turkey. The findings were obtained education level of the producers, the number of individuals in the family, record keeping, annual total income, newspaper reading, grape yield, grape cultivation area, property and rental land, credit usage, weed control, organic farming knowledge level, organic farming by using variables such as thoughts and grape variety. There are serious differences between conventional agriculture and organic farming. The family structure is effective in production activities. It has been determined that the thoughts of organic farming have changed depending on the age and experience of the producers. Organic grape producers have turned to organic farming due to their desire to sell their products at higher prices with state supports. Also, it has been suggested that organic farming is important in terms of the sustainability of living life all over the world. Increasing producer income and environmental awareness are among the main reasons for the transition to organic farming.

In this study, it was aimed to determine the concentrations of some elements in sediment along depht profile in core collected at the Lake Hazar (Elazıg) and to compared the results according to recent geological periods. For this purpose, the levels of arsenic (As), mercury (Hg), molybdenum (Mo), barium (Ba), uranium (U), tin (Sn), titanium (Ti), lanthanum (La) and beryllium (Be) on every 5 cm of the piston core samples taken as part of a TUBİTAK project (No: 111Y045) from Lake Hazar were detected. The lowest concentrations of Ba, Hg, La, Ti and U were found (111 ppm, 0.01 ppm, 4.4 ppm, 1190 ppm and 0.6 ppm respectively) at 81-83 cm in depth. It was determined that it belonged to 10 000 B.P. and to Holocene Period (10.5 thousand B.P.). The highest concentrations of As, Ba, Hg, Sn, La, Mo, Ti and U were found different depth in the core in Lake Hazar. The highest concentrations of Hg in the core were detected between 4-6 cm that this depth was determined corresponds to present day. The highest levels of As and Ba found that it belonged to Pre-Glacial Period/ Late Pleistocene Period (10.5 thousand B.P.). The highest concentration of other elements (Sn, La, Mo and Ti) determined that it belonged to Last Glacial Maximum Period/Late Pleistocene Period (between 23-16 thousand B.P.). The geological structure of the basin where the lake ecosystem is located, biological and hydrological processes, climatic and anthropogenic factors can be cited as the reasons for these differences.

The aim of this study was to investigate the effects of exogenous Melatonin (100, 300 and 500 µM) and L-tryptophan (125, 250, 375 ppm) applications on some growth parameters of lettuce plants grown under salt stress. The study was carried out under semi-controlled greenhouse conditions in spring (March/April) season. The exogenous applications to lettuce plants were carried out two times as foliar spraying. Salt stress was generated by adding NaCl (0 mM, 100 mM, 200 mM) to irrigation water. The complete randomized design was used with three replications in this experiment. At the end of the study, it was found that the highest doses of exogenous applications had the highest effect on the parameters of the number of leaves, salinity necrosis, fresh leaf weight, fresh root weight, and total surface area of lettuce plants under 200 mM salinity condition. When the effects of the subtract on these values were compared, the effect of melatonin was found to be more pronounced. Leaf width, leaf length, and leaf surface temperature values were not affected by the external application. These values only changed depending on salt concentration. As a result of the study, it was concluded that the application of 500 µM melatonin significantly increased salt tolerance in lettuce plants. However, in order to reach a more general conclusion, the dose ranges and genotype/variety numbers should be increased.

The main purpose of this paper is to review on the effect of irrigation water quality and deficit irrigation on crop yield and water use efficiency. Low quality water for irrigation can impose a major environmental constraint to crop productivity. If salts become excessive, losses in yield will result. To prevent yield loss, salts in the soil must be controlled at a concentration below that which might affect yield. Irrigation application below the full evapotranspiration requirement is termed as deficit irrigation. Deficit irrigation consists of deliberately applying irrigation water in amounts below the plant’s water requirements. Deficit irrigation can be applied at certain periods during the crop’s growing season or throughout its growing season. Yield reductions also occur in a number of crops when subjected to water stress. Yield reductions depend on the crop’s sensitivity to water stress at its various growth stages. In order for deficit irrigation to be an economically viable practice, the revenue lost due to yield reduction should be lower than savings in total cost of production. The goal of deficit irrigation is to increase crop water use efficiency by reducing the amount of water that is applied or by reducing the number of irrigation events. The interaction effects of water quality and DI illustrated that when the two types of stresses; saline and DI were coupled together, a serious reduction occurred on total dry biomass and total yield. The interaction effects of water quality and deficit irrigation illustrated that when the two types of stresses; saline and deficit irrigation were coupled together, a serious reduction occurred on total dry biomass and total yields.

Thirteen different mostly consumed cheese samples were obtained from different provinces in Turkey and were investigated in terms of contents of ergosterol, patulin and Ochratoxin A (OTA). Ergosterol, patulin and OTA analyses were carried out by using the apparatus of high-performance liquid chromatography (HPLC). Ergosterol contents of samples ranged from 30.27±0.69 to 144.76±9.41 mg/kg. The values of OTA in the samples were ranged from 6.96±0.05 to 41±0.2 µg/kg. Ergosterol was significantly correlated with OTA (r = 0.99, R2 = 0.98). According to this high correlation, ergosterol might be used as a more readily measurable indicator of potential OTA production. No patulin was detected in all samples. Absence of patulin on cheese samples may be explained with unsuitable media for patulin producing.

Vegetables; in terms of vitamins, nutritional fiber, phenolic component and mineral matter has an important role in human nutrition. There are many species of purple-red vegetables, some of which are well-known, such as red beet (Beta vulgaris), black carrot (Daucus carota ssp. sativus var. atrorubens Alef), black radish (Raphanus sativus L. var. niger), purple cabbage (Brassica oleracea L. var. capitata f. rubra). Purple or red vegetables have higher antioxidant potential compared to other vegetables, which have many beneficial properties such as antimicrobial, antifungal, anti-inflammatory and liver protection. Each of vegetables which is black carrot, beetroot, black radish and purple cabbage contains p-coumaric acid, betaxanthin, ellagic acid and indole-3-carbinol respectively. In this study, Antifungal effect of ethanol extracts obtained from red beet, black carrot, black radish which are inner and peel part, purple cabbage against 7 different subspecies of Penicillium, 6 different subspecies of Aspergillus and Mucor racemosus, Botrytis cinerea, Geotrichum candidum, Cladosporium claudosporioides, Rhizopus nigricans species were determined by using disk diffusion method. As a consequence; it was determined that 7 different samples had antifungal effect on 18 different mold species at various rate. The highest antifungal effect was observed with 23.05±0.05 mm zone diameter against A. fumigatus in black radish inner part ethanol extract. This value was pursued by red beet inner part ethanol extract against M. racemosus with 21.44±0.12 mm zone diameter. It was concluded that the lowest antifungal effect on mold species except for P. citrinum, P. solitum and B. cinerea in purple cabbage extract.
