Bu araştırma Temmuz 2011 ve Mayıs 2012 tarihleri arasında mevsimsel olarak gerçekleştirilmiş olup çalışmada Giresun sahillerinde denize dökülen Batlama Deresi’nde dağılım gösteren bazı balık türlerinin kas ve solungaç dokularındaki ağır metal birikimleri değerlendirilmiştir. Analiz edilen balıklarda ağır metal birikimleri ortalama ppm olarak kas dokuda; Co: 1,47-1,64 Cr: 0,09-0,36, Cu: 0,92-11,0, Fe: 8,01-17,6, Mn: 1,46-2,20, Ni: 2,69-3.55, Pb: 1,83-2,63, Zn: 9,80-17,0; solungaçta; Co: 2,14-3,99, Cr: 0,20-0,58, Cu: 1,32-22,6, Fe: 52,2-140, Mn: 13,1-20,3, Ni: 7,85-13,6, Pb: 2,75-6,28, Zn: 37,5-80,8 düzeylerinde bulunmuştur. Bunun yanı sıra çalışmada, kas doku için günlük ve haftalık alımlar hesaplanmıştır. Bu değerler uluslararası kuruluşlar tarafından bildirilen sınır değerlerinin altında olduğundan, çalışmanın yapıldığı zaman, çalışılan türler ve metaller açısından bu bölgede yakalanarak tüketilen balıkların insan sağlığı üzerine herhangi bir tehdit oluşturmayacağı söylenebilir.

Turkish white cheeses after brine salting were subjected to high pressure processing (HPP) at 50, 100, 200 and 400 MPa for 5 and 15 min and the samples pressurized for 15 min were ripened in brine for 60 days. The effects of HPP on the salt distribution in external, middle and internal zones of cheese after pressurization and on the salt uptake of whole cheese block during ripening were investigated. HPP did not change the values of moisture, salt and salt in moisture in different zones of cheese. Furthermore, pressure holding time had no effect on salt distribution in cheese. The salt contents of un-pressurized and pressurized cheese samples were equilibrated on the 14th day of ripening, and then stabilized, with no high pressure effect. As a result, HPP at pressures up to 400 MPa did not significantly affect neither salt distribution after high pressure processing nor salt uptake during ripening. However, a slight increase in moisture at the pressures of 200-400 MPa on the 60th day of ripening, which was not significant, might warn further increases in moisture of white cheese for longer ripening periods than 60 days. Higher pressure applications may alter all those values in white cheese because of textural changes.

Multistoried agroforestry systems as a form of jackfruit-eggplant based is increasingly recognized as a promising option to counteract the catastrophic effects of climate change through providing multifaceted benefits. Unfortunately, farmers of Bangladesh did not manage their jackfruit orchard in a scientific manner. Therefore, the present study was aimed to assess the productivity and profitability of jackfruit-eggplant based agroforestry system after modification from a traditional jackfruit orchard during the period of July 2012 to December 2013. Five treatments covering four orientations of jackfruit tree and an open field was used as a control treatment. To observe the growth and economic performance of the system; soil moisture and temperature, DBH, number of fruits per tree, fruit length, fruit width, fruit weight, total yield, BCR, and LER were calculated following different established methods. The yield of jackfruit dramatically increased by 81% in the agroforestry system in compared to sole cropping, while eggplant shows inverse trend. Soil moisture was high in agroforestry system than that of control plot while soil temperature shows reverse pattern. Indeed, agroforestry system had some negative effects on growth performance of understorey crops. Despite, net return and BCR from jackfruit based agroforestry system were 5.58 lakh and 4.56, which was 66 and 45%, respectively higher than sole cropping systems. The LER of jackfruit-eggplant based agroforestry system was 2.17. Considering the main findings, we can elucidate that jackfruit orchards can be transformed to agroforestry system for maximizing production, generating income and conserving environment.

The aim of this study was to determine the effects of in ovo injection of Saccharomyces cerevisiae (SC) to fertile Ross 308 broiler eggs or dietary supplementation on growth performance, internal organ development, gut histomorphology and cecum microbiota during 14 d of growing period. This study was designed as 2×2 factorial experimental design. Fertile 92 Ross 308 eggs were injected with SC solution 0.2ml at 18d of hatch and 90 eggs non-injected as control, afterward dietary SC supplementation was applied during the 14 d to broiler diet. In this study, 160 broiler chicks were used in four treatment groups at 10 replicate for each treatment group and 4 chicks for each replicates. Treatment groups were A) in ovo SC injection + dietary SC supplementation, B) in ovo SC injection + basal diet, C) no injection + dietary SC supplementation, D) no injection + basal diet as control. Live weight, feed consumption, feed conversion ratio and gut histomorphology, caecum microbiota, internal organ weight were recorded at 14 days of age. Live weight gain increased in C group than in the D group. Feed consumption, feed conversion ratio and internal organ weights were not affected by the treatments. Villi length and villi width increased in A group among the other treatment groups in jejunum, villi length increased in A and C groups among the other groups in ileum. Villi length/villi width ratio increased in A group than in the D group in ileum, was not different in jejunum. LAB counts in caecum were higher in A group than those of C and D groups, but was not different from B group. Enterobactericaea count was lower in A and B group than in the D group, was not different from C group. To conclude, results showed that dietary Saccharomyces cerevisiae supplementation increased broiler growth at 14 day by increasing villi development and improving gut health.

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.

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.
