The processes involved in the conversion of cassava tuber into various products generate large volumes of wastes in solid, liquid and gaseous forms. These wastes when discharged into the environment have serious environmental impacts on the natural composition and structure of soil. The aim of this research work was to investigate the effects of cassava whey on the physicochemical properties and metal contents of soil samples around Gari facrory at Erinfun Village along Federal Polytechnic road, Ado-Ekiti. The physicochemical parameters determined were the pH, moisture content, loss on ignition, organic matter, water holding capacity, bulk density, particle density, total porosity, calcium (Ca), magnesium (Mg) and cyanide (CN). Heavy metals determined were lead (Pb), zinc (Zn), copper (Cu), manganese (Mn), cadmium (Cd), chromium (Cr) and iron (Fe). The presence of cassava whey in the soil led to increasing soil acidity, moisture content, water holding capacity, CN, Cr, Ni, Pb and As concentrations while reductions were observed in total porosity, organic matter, loss on ignition, particle density, Ca, Mg, Fe, Mn and Zn concentrations. The results show appreciable variations of physicochemical parameters and heavy metal contents when compared to the control sample.

This study was conducted to determine the Listeria monocytogenes’s presence, serotypes and resistance against various antibiotics in modified atmosphere packaged (MAP) ground and cubed beef samples. Five of ground (5/50-10%) and 3 of cubed beef samples (3/50-6%) were identified as L. monocytogenes positive in MAP samples. Eleven L. monocytogenes isolates that obtained from samples being investigated in term of hlyA gene by PCR method have verified that this gene (100%). In serotyping results, 3 of 8 isolate that obtained from MAP ground beef samples were 1/2a, the other 3 isolate was 1/2b and the remaining 2 isolate was 4b. Also, 1 of 3 isolate that obtained from MAP cubed beef samples were 1/2b, the other one isolate was 1/2c and the last one was 4b. One isolate against (9%) ampicillin, 2 isolate against (18.2%) chloramphenicol, 3 isolate against (27.2%) erythromycin, 4 isolate against (36.3%) oxytetracycline and 4 isolate against (36.3%) penicillin G, 6 isolate against (54.5%) tetracycline and 3 isolate against (27.2%) vancomycin was resistant in 11 L. monocytogenes isolates that confirmed by PCR. The L. monocytogenes isolates were found to be resistant to one or more antibiotics in antibiotic-resistance test results. In conclusion, applying of national residue monitoring program by official authority for prevention of intensive antibiotic use in order to prevent the development of resistant strains to antibiotics has great importance.

Değer zinciri, bir malın üretimiyle başlar, nihai ürünün tüketimiyle sona erer. Çalışmanın amacı, tarımsal değer zincirini açıklayarak, tarımsal değer zincirinde değer yaratan faaliyetleri ortaya koymaktır. Araştırmada literatür taraması yaklaşımından yararlanılmıştır. Tarımsal değer zincirinin yedi aşaması söz konusu olup, bunlar sırasıyla girdi tedariki, üretim, üretici örgütleri, tüccarlar, işleyiciler, toptancılar ve perakendeciler şeklindedir. Değer zincirinde ürün kalitesinin yükseltilmesi, üründe farklılaşma sağlanması ya da sistemin etkinliğinin artırılması yoluyla rakiplere karşı avantaj sağlanması hedeflenmektedir. Tarımsal ürünlerin üretim maliyetlerine, kullanılan girdi miktarından teknoloji transferine kadar birçok unsur etki etmekte iken, organik tarım ve iyi tarım uygulamaları gibi yaklaşımlarla üründe farklılaşma sağlanarak değer yaratılabilmektedir. Tarım sektöründe büyük işletmeler değer zincirini bir bütün olarak ele alabilmelerine rağmen, süreçten erken çıkmak zorunda kalan küçük ve orta ölçekli işletmelerin süreçte kalabildikleri sürece değer yaratan faaliyetlere odaklanmaları gerekmektedir. Değer zinciri analizi yaklaşımıyla tarım sektöründeki bazı temel sorunların çözümüne katkı sağlanması mümkün olabilecektir.

Tomato comes as the most commonly produced, consumed and subject for trading in the world. Alongside fresh consumption, on the other hand it forms the most significant raw material source of food industry, especially for tomato paste, frozen and dried vegetable-fruit and canned food industry. Turkey's greenhouse vegetable production field for 2016 year is 675173 decars and Antalya forms 51% of this field. Tomato forms 61.72% of Antalya's greenhouse production. The main material of the research consists of interviews made with producers resided in 5 villages/towns, where greenhouse tomato production is carried out densely in Antalya city, Alanya district. In 48 villages and towns, greenhouse tomato production is carried out, according to the official records. In the chosen areas, 365 producers exist. 20% of these producers (73) form the sample size. In the research, it was determined that the producers' average agricultural land possession is 9.13 decars and in 40.53% of these areas they grew tomatoes. None of these producers are engaged in contractual growing. All of the yield is produced for the edible (as table-top item). After the harvest, all of the products are sold in the wholesales market in county and city. 7.89% of the producers have no information on soilless agriculture, as 10.52% of them think that it has no advantages and 73.36% of them recommend traditional agriculture.

Phytophthora spp., Oomycetes sınıfında yer alan, tek ve çok yıllık bitkilerde kök, kök boğazı ve yaprak yanıklığı oluşturarak ani ölümlere yol açan önemli bir hastalık grubudur. Orman ağaçlarında ilk Phytophthora çalışması, Türkiye ormanlarının en yaygın ağacı olan meşelerde yapılmış ve ülkenin birçok bölgesinde, Phytophthora türlerinin bitkilerde kurumalar ve geriye ölüm belirtileri oluşturduğu, bu hastalıklara P. cinnamomi, P. citricola, P. cryptogea, P. gonapodyides, P. quercina, Phytophthora sp. 1 ve Phytophthora sp. 2’ in neden olduğu, en yaygın türün ise P. quercina olduğu belirlenmiştir. Phytophthora türlerinin yaygın olarak görüldüğü ikinci orman ağacı kestanedir ve ülkemizin hemen hemen her yöresinde Phytophthora kök çürüklüklerine rastlanmıştır. Kestanede dört türün hastalık yaptığı, bunlardan P. cambivora’nın daha çok iç bölgelerde bulunduğu, P. cinnamomi’ nin ise ılıman yerlerde sahil bölgelerde bulunduğu, P. plurivora ve P. cryptogea’ nın daha az oranda bulunduğu belirlenmiştir.

Since the national farmers' day on May 12, 2017 in Kaya, Burkina Faso, the debate on agriculture has been to establish the agricultural entrepreneurship through the concept of agriculture as a family business (ACEF). And it is from this perspective that this study was conducted to analyse the financing possibilities open to family farming and to deduce the constraints of the transition from family farming to enterprise farming. To do this, we used the exegetical method to characterize the existing agricultural formations, to identify the means of financing and the constraints of the agricultural transition. The agricultural sector is strongly dominated by family farming with low physical and financial capital. The means of financing are self-financing and external financing. However, the transition will not be without problems because there are technical and political constraints to overcome.

This study was carried out to detect the content of amino acid in female and male specimens of blue swimming crab (Portunus segnis) obtained from (including 12 male crab and also 12 female crab) North Eastern Mediterranean Sea, Turkey. The protein was identified as 17.63% and 18.13% for female and male crab respevtively. Totally 9 essential amino acids were recorded in the present study. Lysine and leucine constituted the highest essential amino acid (EAA) concentrations in P. segnis. This species was found to be in good score in terms of the level of EAA and the EAA/Non-EAA ratios when compared with other economical crab species.

Bu çalışmada kiraz ve kayısı ağaçlarından sızan reçineler yenilebilir kaplama materyali olarak kullanıldı. Reçinelerin yenilebilir kaplama olarak uygun olup olmadıkları bazı kimyasal özellikleriyle incelendi. Karbon, hidrojen, azot ve kükürt yüzdeleri elementel analiz ile belirlendi. Yapılan analizler sonucunda her iki reçinenin de fenolik madde bakımından zengin olduğu bulundu ve antioksidan kapasitelerinin yüksek olduğu tespit edildi. Termal analizlerle reçinelerden elde edilen filmlerin ısıya karşı davranışları ve ağırlık kayıpları belirlendi. Bu analizlere göre, filmlerin 400°C’ye kadar ısıya dayanıklı oldukları bulundu. Filmlerin SEM ile elde edilen yüzey görüntülerinin homojen ve düzgün bir yapıda oldukları görüldü. Daha sonra, reçinelerden elde edilen film çözeltileriyle çilek ve yenidünya meyveleri kaplandı. 4±1°C’de buzdolabında muhafaza edilen kaplamalı/kaplamasız meyveler; raf ömrü, organoleptik ve mikrobiyolojik özellikler bakımından karşılaştırıldı. Filmlerin kaplanmış meyvelerin raf ömrünü uzattığı görüldü. Depolama sonunda kaplamasız örneklerin toplam bakteri, maya-küf ve koliform bakteri düzeyleri en yüksek seviyedeydi. Ayrıca, kaplamalar meyvelerin organoleptik özelliklerini olumlu etkiledi. Duyusal analiz testine göre kaplamalı meyveler, kaplamasız meyvelerden daha yüksek puanlara sahip oldular. Kiraz ve kayısı ağacı reçineleri yenilebilir kaplama olarak kullanıma uygun materyallerdir.

In this study, the factors affecting on land value in urban sprawl were analysed via regression analysis. In the analyse, the nominal value of land was taken to be dependent variable while factors affecting the value of the land in urban sprawl were considered to be independent variables. 9 factors that were thought to affect the value of the land were handled. In this study, 3 separate models were analyzed, and all models provided statistically significant results. The basic reason for applying three separate models is to be witness the effects by including the variables in different categories (environmental, social amenity and economical factors) separately to the model. As a result of these analyses, all of environmental, amenity and economic factors should be considered for valuation of urban sprawl.
