Nano Alemu Daba | Abduletif Ahmed | Muktar Mohammed
The study was conducted on farmers' field in sofi district of Harari Regional State during 2013/2014 main cropping season, eastern Ethiopia, to investigate the impact of brewery sludge on sorghum production and soil fertility. The treatments comprised seven levels of brewery sludges (0, 2.5, 5.0, 7.5, 10.0, 12.5 and 15.0 t ha-1) and NP inorganic fertilizer at recommended rate, arranged in randomized complete block design with four replications. Application of brewery sludge at 15 t ha-1 significantly increased the yield and biomass yield of sorghum by 79 and 85% over control and by 57 and 67% over NP application, respectively. There was no effect of brewery sludge application on heavy metals concentrations in soil after crop harvest, compared to international standard tolerable level. Co and Se levels were high in the control as well as in the soils treated with brewery sludge indicating the already high concentration of these heavy metals in the soils of the area. Plots, which received higher brewery sludge application, resulted in decreased or less percentage of grain nitrogen content showing the independence of grain protein content on lower brewery sludge level. The nitrogen uptake by sorghum grain, straw and the total was maximum (52.68, 44.25 and 79.03 kg ha-1, respectively) with the application of brewery waste sludge at 10 and 15 t ha-1 which were significantly higher than the other brewery sludge and NP mineral fertilizer applications.

In this study, the European Sea Bass (Dicentrarchus labrax) were fed rich canola oil which is containing monounsaturated fatty acid (MUFA) and rich cottonseed oil which is containing n-6 polyunsaturated fatty acid (PUFA) and the effects of these feeds on some hematological parameters were investigated. Experimental fish were fed two times daily with 100% fish oil (FO-control), 100% cottonseed oil (CSO), 100% canola oil (CO) and 50% CSO - 50% CO (CSO50-CO50) for 162 days. End of the experiment, total erythrocyte (RBC) amount was highest in the CSO group 269.0 x (104 mm3 -1) compared to all other groups. Leukocyte (WBC) 96.280 x (103 mm3 -1), monocyte, lymphocyte and neutrophil amounts showed significant increases in only CSO group. Therefore, in terms of fish health and welfare, the exclusive use of cottonseed oil without mixing with the other vegetable oils in sea bass diet formulation can be a viable alternative to fish oil since it has the most suitable fatty acids.

Ventilation is one of the methods used to obtain the biological optimal point of environmental factors needed for the plants in greenhouses. In the greenhouses, air change coefficient must be more than 50 h-1 in order to supply effective air ventilation. Temperature differences like air change coefficient can be regarded as a criterion to determine efficiency of ventilation in the greenhouses. In this study, the temperature values were calculated by using energy balance and Bernoulli equation at different ventilation opening ratios (AV/AG) depending on climatic properties in the Mediterranean region (Antalya). If was found that, based on temperature and radiation values of Antalya province, 20% ventilation opening rate is sufficient in the roof area. A temperature difference (∆T) of 1K can be achieved with a 50% shading of radiation and a 20% ventilation opening in June in the Mediterranean region. However, additional cooling is necessary in the greenhouses around noon hours because outdoor temperature is greater than 30°C.

Asma yaprak kıvırcıklık (grapevine leafroll) hastalığı geçmişten bu yana bağ virüs hastalıkları içerisinde ekonomik önem derecesi yüksek olan dünya çapında yayılım gösteren bir hastalıktır. Closterovirus cinsine ait virüs üyeleri içerisinde, Asma yaprak kıvırcıklık virüsü 1 (Grapevine leafroll-associated virus 1) (GLRaV-1) en eski olanıdır. Bağlarda önemli verim kayıplarına neden olan bu virüs, özellikle yapraklarda kıvrılma simptomu ile tanımlanır. Nar bitkisi, ekonomik değeri yüksek bitkiler arasında yer almakta olup henüz az sayıda virüs hastalıkları tanımlanmış ancak son yıllarda yürütülen çalışmalarda bu bitkinin de GLRaV-1’in konukçusu olabileceği bildirilmiştir. Bu çalışmanın amacı, bağ ve narlardan elde edilen GLRaV-1 izolatlarının genomik olarak kıyaslanmasıdır. Bu amaçla, 2014 yılında Hatay ve Niğde illerinden toplanan asma ve nar örneklerinden total RNA ve dsRNA izolasyonları yapılmış, virüs genomuna özgü 2 farklı bölgenin (hareket (movement) proteini (p24) ve ısı şok (heatshock) proteinini (HSP70h) çoğaltan primerler kullanılarak RT-PCR ile analizleri yapılmış elde edilen ürünler klonlanmış ve sekans analizleri yapılmıştır. Ayrıca Closterovirüs’ün HSP70h genine özgü dejenere primer kullanılarak DOP-PCR analizleri yapılmıştır. DNA dizi analizlerinin sonunda elde edilen kısmi genomun, BLAST analizleri yapıldıktan sonra filogenetik analizleri yapılmıştır. Bu çalışma sonunda, yeni bir konukçu olduğu düşünülen nardan izole edilen GLRaV-1 izolatlarının asma izolatları ile kıyaslamalı olarak analiz edilmesi sağlanmış ve izolatlar arası yüksek oranda benzerlik olduğu tespit edilmiştir.

Newly developed Bambara groundnut (Vigna subterranea L.) seeds (Accessions No: TVSU 5 – Bambara Groundnut White (BGW) and TVSU 146 – Bambara Groundnut Brown (BGB)) were collected from International Institute of Tropical Agriculture (IITA), Nigeria, planted and harvested. The effects of processing methods (soaking and boiling) on anti-nutritional factors and oligosaccharides content and protein digestibility of BGW and BGB compared with Bambara groundnut commercial (BGC) seeds were investigated. Soaking and boiling significantly reduced the anti-nutritional factors of the samples and the effect increased as processing time was elongated. Sample BGC had lower anti-nutritional factors than BGW and BGB after soaking for 48 h. Tannin contents of the samples were reduced drastically by 99 % throughout the soaking periods. Greatest loss in raffinose level was observed in BGB (59%) and BGW (50%) after boiling for 60 min compared with BGC (43%). The loss in stachyose content of the samples varies with processing and BGC (59%) had greatest loss after boiling for 60 min while soaking for 48 h reduced that of BGB and BGW by 57 and 35%, respectively. Boiling for 60 min increased the in vitro protein digestibility of BGB (89.34 %) compared with BGW (87.48%) and BGC (82.89%). Overall, the results demonstrated that soaking and boiling of newly developed Bambara groundnut seeds could improve the nutritive quality of the seeds.

Nitrogen fixation resulting from mutual symbiosis of rhizobia and cultivated legume plants is therefore critical to food security as it directly affects agricultural production. Biological Nitrogen Fixation (BNF) can be an important factor in sustainable agriculture.The isolation and identification of different slow growing and fast growing rhizobial strains from the nodules of two leguminous plant species. Symbiotic nitrogen fixing Rhizobium spp. was isolated from (Lablab purpureus and Vigna sinensis). Nodules samples were collected from plants growing in different Districts of Bangladesh and the Glucose-Peptone Agar (GPA), Congo red, Yeast Mannitol Agar (YMA) containing 2% NaCl were employed to make presumptive decisions on the recognition and classification of the isolated bacterial strains. All the isolates were found with poor absorption of dye Congo red and little or no growth on the media of GPA and without altering the pH. Almost all of the isolates exhibit growth on 2% NaCl, poor growth on GPA, thus confirming the rhizobia. After biochemical tests like catalase test and citrate utilization test isolates were confirmed as Rhizobia. The presence of rhizobia on root nodules of leguminous Plant. Not only the leguminous Plant but also the rhizosphere contains rhizobia which help in soil fertilization.

Nazlı Ercan | Mustafa Koçkaya
Oxidative stress, which plays an active role in the pathogenesis of various diseases, continues to be relevant in assessing the condition changes such as aggression. Some of Kangal dogs have been found to eat their own puppies during their first 24 hours following birth, as a case called maternal cannibalism. The present study aims to determine the levels of serum malondialdehyde (MDA), which is a product of lipid peroxidation, and serum glutathione peroxidase (GPx) and superoxide dismutase (SOD) enzymes, which are the parameters of antioxidant defense system, and total protein and albumin levels and to show their relationship with cannibalism. The study material consists of blood and blood serum of 30 Kangal dog breed in total, 15 of which have maternal cannibalism and 15 haven’t observed maternal cannibalism as a control group. Glutathione peroxidase, superoxide dismutase, malondialdehyde levels were investigated by means of spectrophotometric method in blood serum of these animals. The difference between the mean values of total protein, GPx, SOD, MDA and albumin was statistically significant in the results obtained. These findings conclude that oxidative stress and antioxidative metabolism plays a role in the pathogenesis of cannibalism in dogs.
