The antibacterial and antioxidant activities of Lavandula stoechas and Crepis sancta extracts on subclinical mastitis bacteria in cows have not been reported to the present day. The aim of this work was to investigate of the antibacterial and antioxidant potential of methanol extract from L. stoechas and C. sancta. Methanol extracts were screened for antibacterial activity against mastitis pathogens. The antibacterial activity was tested using disc diffusion and broth dilution method. In addition, the plant extracts were tested against the stable DPPH (1,1-Diphenyl-2-picrylhydrazyl) free-radical. Additionally methanol extracts were screened for enzymatic antioxidant activity. The methanol extract of C. sancta showed maximum inhibition zone against S. aureus-18 (16 mm). MIC (minimum inhibition concentration) value was determined as 3250 µg/mL for test bacteria. The highest radical scavenging capacity (62 %) was obtained from the flower extracts of L. stoechas and the leaf extracts of C. sancta. The methanol extract of C. sancta displayed a strong antioxidant activity (trolox equivalent = 1.6 mM/g). It was determined that the activities of catalase (CAT) and ascorbate peroxidase (AP) enzymes were higher at the flowers of L. stoechas compared to the leaves. The extracts of L. stoechas and C. sancta leaf and flower have antibacterial and antioxidant potential against subclinic mastitis causative agent Staphylococci species.

Agricultural production and income are important for Mediterranean region of Turkey. The region and especially Antalya province is well-known with greenhouse production. For greenhouse production achieving sustainability is important for meeting domestic and foreign demand and security of production lands. In order to measure the potential for improving greenhouse operators 281 farmers were surveyed in 2015 in Antalya and profit inefficiency and factors affecting inefficiencies of operators were estimated using stochastic frontier approach. Accordingly, the average inefficiency level of operators was found as 57 %, signifying the potential for improvement. The main objective was to undermine the impact of landownership on this inefficiency level. Yet, the impact of other relevant factors referring to greenhouse structures and famers’ characteristics were estimated as well. While level of education seemed to reduce inefficiency, household size had appeared as an inefficiency rising factor referring to professional labour endowment of greenhouse production in Antalya. Being renter of land appeared as an inefficiency rising factor as well as holding plastic house or having located in the western parts of Antalya. These findings indicated importance of supporting improved production technologies and use of strengthened structures. In addition, it appeared as essential to provide incentives to renters to cope with their costs.

The study aims at estimating the effect of producers’ socio-economic characteristics and the farm structure on the probability of becoming a member of an agricultural organization. For this aim Ordered Probit Model was applied. The data of 2010 production period was collected from 66 dairy cattle farms through questionnaires based on stratified random sampling method. While 74.2% of producers were not a member to any organization, the remaining 18.2 and 7.6% were members of one and more than one organizations, respectively. The result of study showed that the variables of experience, education level, milk yields, milking machine existence, and record keeping rate increased the probability of becoming a member to any agricultural organization. Government financial, technical and educational supports towards increasing the number of cattle farms, with high educated and experienced labor and high productivity levels, which are associated in an agricultural organization, could promote the willingness of producers in the region in participating of agricultural organizations as a member.

The aim of this study was to determine the effect of deficit irrigation on yield for cabbage grown under unheated greenhouse condition. The research was carried out at the Agricultural Research Station of Yenişehir High School of Uludağ University in Bursa, Turkey, in 2008. In the study, water was applied to cabbage as 1.00, 0.75, 0.50, 0.25 and 0.00% (as control) of evaporation from a Class A Pan corresponding to 2 day irrigation frequency. Irrigation water applied ranged from 70 to 520 mm and water consumption ranged from 90 to 548 mm. The effect of irrigation water level on the yield, head height, head diameter, head weight and dry matter were found to be significant. The highest yield was 72.8 t ha-1. Crop yield response factor for cabbage (ky) was found as 1.036. The highest values of water use efficiency (WUE) and irrigation water use efficiency (IWUE) for 2008 year of K2cp treatment was calculated to be 0.143 kg m-3 and 0.137 kg m-3, respectively. K2cp application (75%) can be recommended as the most effective irrigation level for the cabbage to which drip irrigation is applied under scarce and unheated greenhouse conditions.

Nezahat Turfan | Ekrem Mutlu
In this study, resistance mechanism of two wheat genotypes against salt, heavy metal, lime and drought (50%) treatments were investigated in summer Cumhuriyet-75 and winter Selimiye-95. According to results chlorophyll a, b, total chlorophyll and carotenoid level increased in FeCl3, drought and 225 mM NaCl in Cumhuriyet-75 but they were higher at NaCl, FeCl3 and ZnCl2 treatments in Selimiye-95 comparison to control. While H2O2 content rose all stres treatments in both varieties but Malondialdehyde (MDA) decreased in Selimiye with all applications. The amount of proline is lower in Cumhuiyet-75 but higher in Selimiye-95. Total soluble protein was found higher at salt concentartion and drought in both varieties. Ascorbate peroxidase (APX), Süperoxide dismutase (SOD) activity increased in salt and FeCl3 in Selimiye-95 but SOD ativity were higher at salt treatments in Cumhuriyet-75. And also in both varieties APX and Guaiacol peroxidase (GuPX) increased at FeCl3 but Catalase (CAT) were higher in only FeCl3 in Cumhuriyet-75. As a result Selimiye-95 showed tolerance to salt and FeCl3 with high photosynthetic pigment, proline and soluble protein content with lower MDA but it is sensitive to NiCl2 and drought. Whereas Cumhuriyet-75 cultivar is resistan to drought, FeCl3 and 225 mM NaCl depended on pigment, protein content and APX, CAT, GuPX and SOD activities. When all the data are taken into consideration, it was concluded that the responses of the varieties to the treatments changed according to the type and concentration of stress, and Selimiye-95 variety was tolerant compared to Cumhuriyet-75 variety.

In the present study, we aimed to evaluate the anticancer activities of Cetraria islandica (C.islandica) extracts on MCF-7 breast cancer cell lines. Cell viability, protein levels, apoptotic cells number, F-actin distribution were measured. Cell viability of MCF-7 breast cancer cells was found to be reduced in a dose-dependent manner.EC50 values of C.islandica on MCF-7 cells were found to be 9.2047 E-5 g/ml (cell amount) by using intelligence system. Expressions of p53, caspase 3 and Bcl-2, were shown to be elevated after low doses of extract and diminished after high dose treatments. PPAR- protein level was decreased, although AMP-activated kinases-α1 (AMPK-α1) protein level was increasedin its extract groups. ERK1/2 protein level was also elevated in its extract groups. 125 mg/ml of extract treated cells show a low decrease in actin filament density. MCF-7 cells with C.islandica treatment for 24 h increased the apoptotic cell percentage, though the cells-treated with C.islandica for 48 was high necrotic cells percentage. Consequently, the C.islandica extract treatment causes to elevate ERK1/2 and AMPK-α1 protein levels, resulting in PPAR- and then triggers the apoptosis by modulation caspase-3 and P53 protein levels. Therefore, C.islandica might be a good candidate for anticancer tissue, especially soft tissue tumours.

Pheasant rearing is rated in three main categories: show and hobby, public interest, and stocking for game birds and edible purposes. The goal of this pheasant breeding station is to put stocking for game birds in their natural habitat, mainly in the Karadeniz region. Contribution to the issues related to incubation in this station and determination of effective reproduction age by setting production period. The aim of this study is to determine how significant performance criteria like egg production, fertility, hatchability and embryonic mortality are, depending on age and on seasonal changes. Our research has been carried out at the Gelemen Pheasant Breeding Station in Samsun. The pheasant breeds that are used on the farm are made up of 114 male and 800 female pheasants (1♂:7♀), of Hungarian and Caucasian genotypes. During the egg-laying period, which lasts for 16 weeks from the end of March (at the age of 45 weeks) to the middle of July (at the age of 60 weeks), egg production was recorded daily and evaluated once a week, and incubation yield was recorded nine times in total. Differences between weeks of age, in terms of egg production, egg and chick weights, fertility rate, incubation yield and embryonic mortality, have been found to be statistically significant. However, hatchability has been found to be statistically insignificant.
