This study was carried out in Rize province in 2016, on fresh leaf samples collected from an organic tea plantation. In this study, the aim was to determine the effect of pruning age (1st year, 3rd year and 5th year following the last pruning) and diurnal variability on antioxidant activity and dry matter rate in tea leaves depending on shoot periods. When the pruning age was considered, the highest antioxidant activity was obtained from the plants which were in 5th pruning age in the 1st shoot period with 4991,1 μmol FeSO4/g dw. In terms of the same trait, the effect of pruning age on antioxidant activity during the 2nd shoot period was insignificant, while the highest antioxidant activity in the third shoot period was obtained from 1st pruning age with 7229.2 μmol FeSO4/g dw. As a general average, considering intraday collecting time, antioxidant activity in leaves collected in morning (07.00) and at noon (12.00) was very close to each other, while the collected leaves in the evening (17.00) had higher values. The dry matter rates obtained from the 1st, 3rd and 5th pruning ages were 23.45%, 25.23% and 25.45% respectively. When the shoot period was considered, the lowest dry matter rate was 20.17% in the first shoot period and the highest dry matter rate was 28.8% in the 2nd shoot period and high values were obtained from the leaves collected at noon.

Agricultural technologies are seen as an important route out of poverty in most of the developing countries. However, the rates of adoption of these technologies have remained low in most of these countries. This study aim at shedding some light on an evaluation of climate mitigation agricultural adoption technologies, and its contribution to rural livelihood outcomes in Gurawa district using cross sectional data collected from randomly selected 180 sample households during the 2016 crop production season. Multivariate probit and Propensity score matching was used to identify impacts of adoption technologies, and to identify factors affecting smallholder farmers’ multiple technology adoption decisions. The results showed that the probability of adoption of agricultural technologies are influenced by several factors: family size, economical active members, education level, age of the household head, social status, soil fertility status, distance from extension office, land holding, distance to markets and distance to weather road. The impact evaluation results indicated that on average, the participation household in soil conservation has increased food security status and asset accumulation nearly by 38% and 15%, respectively, however it decreases the rate of poverty nearly by 51 percent. Use of improved seeds increased food security status and decreased poverty rate nearly by 38% and 44%, respectively. On the other hand, use of irrigation technology increased food security status and asset accumulation nearly by 23% and 31.8%, respectively, whereas it decreases the rate of poverty nearly by 29 percent. Similarly, adoption of row planting methods increased food security status and asset accumulation nearly by 28.7% and 15.5%, respectively, whereas it decreases the rate of poverty nearly by 51.5 percent. Therefore, policy makers should give due emphasis to the aforementioned variables to increase adoption technologies and improve the livelihood of the rural households.

Sustainability and development of the dairy enterprises are dependent on competitiveness. Determination of the performance of the enterprises requires measurement and analyses of the financial performance of the enterprises. The ability of dairy enterprises to continue and grow is dependent on competitiveness. It requires that the financial performance of the farm enterprises be measured and analysed in order for the enterprises to be able to detect the competition power in a healthy manner. The aim of the study is to analyse the financial performance of the dairy enterprises in Konya province by determining the capital structure. Çumra, Karapınar and Ereğli districts constituted 15% of the number of bovine animals, were selected by using sampling method. The number of dairy cattle in these enterprises constituted the main frame of the population the primary data collected from 125 dairy farm enterprises with questionnaire technique through stratified sampling method with 95% confidence interval and error margin of 5%. The capital structure of the enterprises surveyed in the research area was classified according to their functions and the average active capital of the enterprises was calculated as 845,330.85$. 67.87% of the active capital is composed of land capital, 31.70% is composed of fixed enterprises capital and 0.43% is variable working capital. The economic profitability level (EP) was determined as 6.90% and the financial profitability level (FP) indicated the success of the enterprise was calculated as 7.06%. The capital turnover rate, an important indicator in the success and comparison of the enterprises, is 28.22%. As a result, their development and competitiveness are slow, because they do not use enough business and investment capital.

Bu çalışmada yeme antibiyotik (amoksisilin+klavulanik asit) ve probiyotik ilavesinin gökkuşağı alabalıklarında (Oncorhynchus mykiss) bazı immünolojik ve serum biyokimyasal sağlık karakteristikleri üzerine etkilerinin araştırılması amaçlanmıştır. Yeme ilave edilen antibiyotik veya probiyotik katkılarının lizozim aktivitesi, myeloperoksidaz aktivitesi, serum total protein, albümin, globülin, trigliserit ve kolesterol değerleri üzerine herhangi bir etkisinin olmadığı belirlenmiştir. Antibiyotik ile beslenen balıkların serum glikoz düzeyleri kontrole göre önemli oranda artmıştır. Bununla birlikte antibiyotik ile beslenen balıkların GOT değeri kontrole göre önemli oranda azalmıştır. Ayrıca LDH ve ALP değerleri antibiyotik ve probiyotik ilavesi ile kontrole göre azaldığı belirlenmiştir. Bu çalışma, tek bir deneysel model olup farklı balık türlerinde ve farklı balık patojenlerinde karşı probiyotik kullanımı farklı dozlara veya zamana bağlı olarak değişebilir. Bu nedenle bu çalışma çeşitli kan parametrelerinin değerlendirilmesi açısından diğer çalışmalara ışık tutmaktadır.

Yumurtacı tavuk rasyonlarına farklı seviyelerde Bor (orthoborik asit) ilavesinin bazı önemli yumurta sarısı parametreleri üzerine etkisini tespit etmek amacıyla yürütülen çalışmada, 62 haftalık 288 adet Lohman yumurtacı ticari hibrit 12 hafta boyunca 0, 50, 75 ve 150 mg/kg seviyelerde B içeren dört farklı rasyonla yemlenmişlerdir. Araştırma 18 tekerrürlü olarak yürütülmüş ve her bir tekerrürde 4 adet tavuk bulundurulmuştur. Araştırma boyunca 16 saat aydınlatma programı uygulanmış, yem ve su ad-libitum olarak verilmiştir.

Genetic diversity estimation among different species is an important tool for genetic improvement to maximize the yield, desirable quality, wider adaptation, pest and insect resistance that ultimately boosting traditional plant breeding methods. The most efficient way of diversity estimation is application of molecular markers. In this study, twenty random amplified polymorphic DNA (RAPD) primers were utilized to estimate the genetic diversity between ten sunflower genotypes. Overall 227 bands were amplified by 20 primers with an average of 11.35 bands per primer. RAPD data showed 86.34% polymorophic bands and 13.65% of monomorophic bands. Genetic similarity was ranged from 50.22% to 87.22%. The lowest similarity (50.22%) was observed between FH-352 and FH-359 and the maximum similarity 87.22% was observed between A-23 and G-46. Polymorphic information content (PIC) values were varying from 0.05 to 0.12 with a mean of 0.09. Cluster analysis based on RAPD results displayed two major distinct groups 1 and 2. Group-2 contains FH-352 which was the most diverse genotype, while group-1 consists of few sub groups with all other genotypes. Ample diversity was found in all the genotypes. Present study reveals novel information about sunflower genome which can be used in future studies for sunflower improvement.

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.

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.
