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.

Competition is fierce in the world markets of agricultural products. It is especially harder for developing countries to compete with the wealthier industrialized countries. Canada entered in the lentil production mainly for export purposes in the early 1990s and exports nearly all of its lentil products every year. As Canada has become the dominant power in lentil trade, Turkey’s lentil production has declined notably. In the study, Turkey’s adaptation to this trend is investigated. Based on the results, it is concluded that Turkey’s market share has not changed in its traditional markets and its export has risen both in quantity and value. For instance, Turkey’s lentil export has increased from 127 Thousand tons in 1997 to 178 Thousand in 2013. This is achieved through partnerships between Canadian and Turkish entrepreneurs. Furthermore, lentil producers in Turkey have shifted to alternative crops, which yields higher income.

Çalışma hayvansal ürün üreticilerine verilen devlet destekleri ile ürünlerin üretim miktarı arasındaki ilişkiyi süt ve dana eti örneğinde incelemeyi amaçlamaktadır. Bu amaçla Türkiye için, 1986-2016 yılları arası veriye dayanarak süt ve dana eti için ayrı ayrı denklemlerle hata düzeltme modelleri tahmin edilmiştir. Eşbütünleme ilişkisinden kısa dönem Granger nedensellik ilişkilerine bakıldığında, süt üretim denkleminde değişkenler arasında istatistiksel olarak anlamlı bir nedensellik ilişkisi bulunamamıştır. Dana eti üretim denkleminde ise tüm değişkenler arasında çift yönlü Granger anlamda nedensellik bulunmuştur. Uzun dönem katsayılar incelendiğinde, süt üretim seviyesi ile piyasa fiyat farklılaşması arasında negatif, üretici destekleri ile pozitif bir ilişki bulunmaktadır. Öte yandan dana eti üretimi ile piyasa fiyat farklılaşması arasında pozitif ancak üretici destekleri ile negatif bir ilişki bulunmaktadır. Bulgular gerek parasal üretici desteklerinin gerekse de parasal destek dışındaki dış ticaret düzenlemesi gibi politikaların ürün türüne göre farklılaştırılması gerektiği düşüncesini desteklemektedir.

To investigate some interesting functional properties of Bacillus spp. in cocoa fermentation processing, 702 strains of Bacillus sp. strains were isolated from six main Ivorian cocoa producer regions. Three mains technological and useful properties for good cocoa beans fermentation were monitored. Among the 386 pectinolytic Bacillus spp. strains, 86.79% of them were confirmed for enzymes production in liquid medium. These 335 pectinolytic Bacillus strains displayed variety of pectinolytic activity with 50.45% of them producing both pectinase and polygalacturonase (PG) enzymes. Among these 169 strains, 70% displayed both the ability to acidify the medium and to degrade the citrate. In mimic conditions of pH and temperature variations as for fermentation heap, 11 strains were able to maintain their activity ranged within 2.12 ± 0.02 to 0.41 ± 0.03 µmol/min/mg of proteins for PG and 2.36 ± 0.03 to 0.25 ± 0.03 µmol/min/mg of proteins for pectinase. Two species (T10T2 and T6HS10) identified as Bacillus subtilus and Bacillus thuringiensis, were selected as the best based on pectinase production level. They were able to continuously produce both pectinolytic enzymes in different conditions of organic acids and ethanol contents. The highlighted properties in this study and the performance of these two strains may make them best candidate as starters for cocoa fermentation control.

This study was aimed to determine the effects of 24-eBL, a steroid growth regulator, on the plant growth, total phenolic content, essential oil content and composition in “Munstead” lavender cultivar belonging to Lavandula angustifolia. For this aim, 24-eBL was applied to plants at four different concentrations (0, 0.75, 1.50 and 2.25 mg/l) twice, at the beginning of budding and 10 days after the first application. The plants harvested during the full bloom period were evaluated for fresh and dry stemmed flower yields, stemless dry flower yield, total phenolic content and essential oil yield and composition. As a result of the study, 24-eBL at concentrations of 0.75 and 1.50 mg/l significantly increased the stemless dry flower yield, total phenolic content and essential oil yield per plant. 24-eBL applications also changed essential oil composition. To conclude, 24-eBL applications can be used to increase the dry flower yield, phenolic and essential oil contents in lavender plants.

In this study, the level of knowledge of the sea turtles that encounter fishing gears from time to time and the attitudes of fishermen on the Turkish coast of the Aegean Sea to these living beings were investigated. Data were collected from a total of 404 fishermen in 98 fisheries cooperatives in 5 provinces (Çanakkale, Balıkesir, İzmir, Aydın and Muğla) by face-to-face survey between August 2016 and October 2017. It was ascertained that the 91% of fishermen, who participated in the survey, do not know what kinds of sea turtles are distributed in the Aegean Sea. The 95% of fishermen do not also know the role of these living beings that show wide range of distribution on world’s oceans and seas, in the ecosystem. Moreover, it is revealed that the fishermen do not have enough knowledge about to perform an intervention in an injured turtle. After getting information from the informative brochures and awareness presentations about sea turtles, fishermen became familiar with the nature of sea turtles, they have changed their attitudes, approach and perspectives to them although they firstly behaved timid to participate in the studies on sea turtles. It is useful to make more social responsibility projects and collaborations with fishermen in areas where these living beings are intense in order to ensure the sustainability of sea turtles on the coast of Aegean Sea.

Bu çalışma mürdümük “M” (Lathyrus sativus L.) tahıl ikili karışımlarının silaj verimi ve kalitesini belirlenmek amacıyla yürütülmüştür. Tahıl olarak yulaf “Y” (Avena sativa L.) ve arpa “A” (Hordeum vulgare L.) kullanılmıştır. Karışımlar %80:20, 60:40 ve 40:60 tohum oranlarıyla ekilmiş, kontrol olarak mürdümük ve tahılların yalın ekimleri de kullanılmıştır. Hasat yalın tahıllar ve karışımlarda tahıllar süt olum, yalın mürdümükte ise tam çiçeklenme döneminde yapılmıştır. Silaj örneklerinde; fiziksel gözlemler (renk, koku, strüktür) ile kuru madde, ham protein, ham kül, laktik asit, asetik asit, bütirik asit, potasyum (K), fosfor (P), kalsiyum (Ca), magnezyum (Mg), demir (Fe), çinko (Zn), mangan (Mn), kobalt (Co), bakır (Cu), selenyum (Se) ve sodyum (Na) içerikleri belirlenmiştir. Karışımların silaj verimi 703,6 (%100M) – 1939,0 (%80M+%20A) kg/da arasında değişmiştir. En yüksek laktik asit içeriği %4,078 ile yalın arpada belirlenmiş ancak, %40M+%60Y (%3,198) ve %40M+%60A (%2,937) karışımları da yalın arpa ile aynı grupta yer almıştır. Karışımların asetik asit ve bütirik asit değerleri ise %0,001–0,187 ve %0,312–1,101 arasında değişim göstermiştir. Mineral içerik bakımından %100M ve %60M+%40Y silajları diğer karışımlardan daha yüksek değere sahip olmuştur. Sonuç olarak, yalın ekime oranla mürdümüğün tahıllarla ekilmesi verimi önemli ölçüde arttırmıştır. Arpa hem yalın olarak hem de karışımlarda yulaftan daha iyi performans göstermiştir. Bu itibarla mürdümüğün arpa ile 60:40 tohum oranında karışık ekilmesi silaj verimi ile kalitesi açısından daha uygun görülmüştür.

The effects of ground flaxseed (0-0.5%) and pH (3.88-8.12) on the emulsion properties of beef were studied using a model system. A central composite rotatable design was used to determine the response surface. pH, flaxseed and their interactions had significant effects on the emulsion properties of beef. pH and the interaction between pH and flaxseed increased emulsion capacity (EC). Flaxseed and pH increased emulsion stability (ES) until a critical point, which was reached at a flaxseed level of 0.42% and a pH of 7.02. pH decreased emulsion density (ED) and increased emulsion activity (EA). Moreover, the interaction between pH and flaxseed on EA was found to be significant. pH and flaxseed increased emulsion viscosity (EV), and the increasing rate was higher in basic medium than acidic.

The effects of combinations of modified atmosphere packaging (MAP) with potassium permanganate (KMnO4) based ethylene scrubbers on the storage life and fruit quality of nectarine (Prunus persica cv. Bayramiç Beyazı) were investigated. Three different types of ethylene sachets (contained 3, 7 and 10 g KMnO4) were used and placed beside fruits in polypropylene baskets then lined with MAP. Fruits were stored at 0-1°C and 90% relative humidity throughout 40 day. During the cooling storage period, O2 and CO2 percentage in MAP, fruit firmness, total soluble solids, titratable acidity, ascorbic acid, total flavonoid content, total phenolic content, total antioxidant content and chilling injury (CI) were determined at 10 day interval. KMnO4 treated fruits had shown delayed ripening, reduced respiration and retained of higher firmness. As the dose of KMnO4 treatment increased, it was determined more positive effect on fruit quality. 10 g KMnO4 treatment was most effective in the retention of higher biochemical compounds and inhibition of CI symptoms. The results indicate that KMnO4 treatment, as well as MAP application, should be highly recommended for retaining the fruit quality of cold-stored ‘Bayramiç Beyazı’ nectarines and fruits treated with 10 g doses of KMnO4 could be stored for 40 days with good quality.

Türkiye’nin toplam su ürünleri üretimi son yıllarda az da olsa giderek azalmaktadır. Bu azalış avcılıktan kaynaklanmaktadır. Avcılığın tersine yetiştiricilik üretimi ise giderek hızla artmaktadır. Toplam su ürünleri üretiminin yaklaşık 1/5’i ihracata konu olurken, su ürünleri dış ticaret hacmi, miktar ve değer olarak giderek hızla artmaktadır. Tarımdaki gelişimin aksine, su ürünleri dış ticaret dengesi, ihracattaki hızlı artışa paralel olarak giderek artan bir şekilde fazla vermektedir. Bu miktar 2016 yılında yaklaşık 610 milyon $’a ulaşmıştır. Su ürünleri ihracatının kaynağını büyük ölçüde yetiştiricilik oluşturmaktadır. İhracat değeri içerisinde levrek (%24), çipura (%21) ve alabalık (%13) başta gelen türlerdir. İhracat pazarları arasında, %65’lik payı ile AB ülkeleri başta gelirken, AB’ni %6,6 ile Japonya, %5,9 ile Rusya, %3,9 ile Lübnan, %3,5 ile ABD izlemektedir. Türkiye’nin su ürünleri dış pazarlamasındaki en büyük sorunu; uluslararası normlara uygun satış ve işlemedeki eksikliklerdir. Nitekim ihracatın yaklaşık %55’ini taze ya da soğutulmuş balıklar oluştururken, %25’ini balık filetoları ve %9’unu dondurulmuş şeklindeki işlenmiş balıkların oluşturduğu gözlenmektedir. Öte yandan, özellikle son yıllarda yetiştiricilikte yem fiyatlarından dolayı yaşanan olumsuzluklar avcılık stoklarını, dolayısıyla dış ticareti de etkilemektedir. Nitekim toplam üretim içinde %49’luk paya sahip olan hamsilerin yaklaşık yarısı, çaça balıklarının ise neredeyse tamamı balık unu ve yağı için kullanıldığından herbivor ve omnivor türlerin yetiştiriciliği gündeme gelmektedir. Bu çalışmada daha çok istatistiksel kaynaklardan sağlanan ikincil veriler ve bu konuda yapılmış çalışma sonuçlarından yararlanılmıştır. Bu çerçevede su ürünleri üretim ve dış ticaretindeki gelişmeler değerlendirilerek, su ürünleri dış ticaretinde karşılaşılan sorunlar ile bu sorunlara yönelik çözüm önerilerinin tartışılması amaçlanmıştır.
