2019
Özlem Pelin Can | Seyda Şahin
The aim of this study was to investigate preservation of the microbiological, chemical and sensory quality of chicken meatballs during storage time by using rosemary essential oil (REO) coated vacuum packaging materials at +4°C. The treatments of chicken meatballs examined in the present study were done by vacuum packaging and packaging materials were prepared by using REO coating 0.3% for group A, 0.5% group B and control group without any additive. The chicken meatballs were analyzed for microbiological (Psychrophilic total viable counts, Enterobacteriaceae, Lactic acid bacteria and Yeast/Mold), chemical (pH and thiobarbituric acid values) and sensory (appearance, taste and general acceptability) parameters. In the study, the microbiological quality of chicken meatballs in samples coated with vacuum packaging with REO had better shelf life compared to control group. The REO 0.3% treatment group samples resulted in a shelf life extension for 9 days compared to the control group samples with a shelf life of 5 days. Thiobarbituric acid values were found to be lower in REO coated groups compared to control. This study was shown that, vacuum packaging materials coated with REO are effective against microbial growth and lipid oxidation and improves sensory qualities of chicken meatballs.

Ademe Mihiretu | Netsanet Assefa
On-farm evaluation and demonstration of different field pea production packages (IFPP, LFPP and LFTP) was carried out for two cropping seasons across districts on seventeen sites in Northeastern Amhara region. The objectives of the experiment were to evaluate the performance of different field pea technologies and to demonstrate the package to the farmers and the extension personnel then to collect feedback from participants. The experiment was conducted by comparing improved variety with its full package along with the local variety under full package practice and farmers’ traditional practice. The agronomic, economic and farmers’ preference analysis clearly indicated that the improved technology is superior to the local variety under full package and farmers’ practice. The average mean grain yields of the improved practices (IFPP and LFPP) were 1901.7 and 1428.3 kgha-1in Dehana, while 1933.3 and 1520 kg ha-1 in Sekota district, respectively. Therefore, the improved field pea technology had a yield advantage of 33.2% and 91.8% respectively from the local cultivar under improved and farmers practice in Dehana. However, the improved technology had 27.2% and 94.6% yield advantage over the local with improved and farmers practice in Sekota, respectively. The marginal rate of return for improved technology in Dehana and Sekota districts was 857.2 and 1344.7%, respectively. Farmers perceived the higher yield potential of the improved technology as a result many of them showed great demand for improved field pea technology. So that pre-scaling up of the improved variety with its production package is recommended to similar agro ecologies.

2019
Khaula Sakhr | Sami El Khatib
The Syrian Sumac (Rhus coriaria) is a widely used spice in the Arab world of attractive economic importance in food, cosmetic and pharmaceutical industries. Meat tenderness is one of the very most important factors for customers’ acceptability. The global objective of this study was to add an additional value to Sumac by evaluating its meat tenderizing effect. Crude sumac fruits were used to create three different extracts (aqueous, ethanolic and purified enzymatic extract). Pectoralis superficialis cuts were treated with the extracts and studied for their shear stress, pH, protein and fat contents and collagen. The hypothesis that Sumac could have a meat tenderizing effect was supported by our results showing a significant decrease in shear stress and protein content with increase in collagen solubility. Moreover, an effect on decreasing meat fat was detected, where the aqueous sumac extract decreased significantly the fat percentage in meat. The active enzymes in Sumac were shown to be variate in nature, lipase and protease, with a significant effect on collagen, thus proving Sumac’s possibility to be potentially used as a meat tenderizer.

Boron is an important micronutrient for growth and development of crop plants. Plant species differ in their requirement of boron for growth. This study was conducted to determine the effect of boron application on the plant characteristics of maize during early leaf stages. The experiments were conducted in Tel – Kaliş agricultural research area at the Mustafa Kemal University in 2015 and 2016 growing seasons. The field experiments were arranged in a split plot design with three replications. Four boron dosages (control, 4, 6 and 8 mg/m2) were applied at three growing stages (V2, V4 and V2V4 (at V2 and V4 stages in two equal parts) as foliar spray. The results revealed that the effects of foliar application of B were positive but statistically insignificant on plant characteristics. Further researches should be conducted for suitable boron application time at different growth stages of maize.

Rabia Talay | Ümmügülsüm Erdoğan
İnsanoğlu yaşamını devam ettirmek için hava ve suya ihtiyaç duyduğu oranda gıdaya da ihtiyaç duymaktadır. Bu ihtiyacını doğal tarım yöntemi ile karşılayan toplumlar zamanla dünya nüfusunun artması ve buna paralel olarak gıda ihtiyacının da arttığı gerekçesiyle yüksek verim sağlayan konvansiyonel tarım yöntemine geçmiştir. Çeşitli riskler (kimyasal ilaçlar, kimyasal gübreler vb.) taşıyan bu yöntem bilim insanları arasında farklı görüşlerin ortaya çıkmasına sebep olmuştur. Bu nedenle konvansiyonel tarıma alternatif bir yöntem olarak organik tarım ortaya çıkmıştır. Günümüzde tüketicilerin de bilinçlenmeye başlaması ile birlikte tüketiciler gıdaları sağlık açısından sorgulamaya başlamışlardır. Bu anlamda gıdanın besin kalitesi ve duyusal kalitesi önem kazanmıştır. Bitkisel (meyve/sebze, tahıllar vb.) ve hayvansal (et, süt vb.) kaynaklı bütün gıdaların kalitesi tarım yönteminden etkilenmektedir. Bu çalışmada iki farklı tarım yönteminin gıdalar üzerinde oluşturduğu riskler ile gıdaların besinsel ve duyusal kalitesi üzerine etkileri hakkında bilgi verilecektir.

Belediye çöplüğü olarak adlandırılan ve çöplerin düzensiz olarak depolandığı alanlar çevrenin yaşam kalitesini düşürmesinin yanında toprağa ve su kaynaklarına zarar vermektedir. Bu alanların en önemli etkisi depolanan çöplerin içerdiği zararlı maddelerin çevreye yayılması, toprakta birikmesi ve taban suyuna karışmasıdır. Bu çalışmada uzun yıllardır düzensiz çöp depolama alanı olarak kullanılmış olan Çorlu düzensiz çöp depolama alanının, yakınında bulunan tarım alanlarına kirletici etkisi incelenmiştir. Bu amaçla depolama alanı ile Çorlu deresi arasında kalan ve tarım yapılan alandan örneklemeler yapılmıştır. Çöp depolama alanına farklı mesafede 22 noktadan ve 3 farklı derinlikten toplam 66 toprak ve 14 bitki örneği alınmıştır. Toprak ve bitki örneklerinde Magnezum (Mg), Potasyum (K), Kalsiyum (Ca), Fosfor (P), Demir (Fe), Mangan (Mn), Bakır (Cu), Çinko (Zn) analizleri yapılmıştır. Ayrıca verilerin daha kolay anlaşılırlığını sağlamak için, Coğrafi Bilgi Sistemleri (CBS) yardımıyla makro ve mikro elementlerin dağılım haritaları yapılarak, toprak ve bitkide bulunan miktarların daha kolay anlaşılabilirliği sağlanmıştır. Analiz sonuçlarına göre toprakların element içerikleri ile çöp alanı arasında mesafe ile ilgili bir ilişki bulunamamıştır. Araştırma alanının eğimli olması ve bahar yağışlarının topraklarda yıkanmaya neden olması toprakların element konsantrasyonunun değişmesine neden olmuştur. Ayrıca çalışma alanının tekstürü kumlu tından kile kadar değişiklik göstermektedir. Toprak analiz sonuçları kil içeriği yüksek olan noktalarda element konsantrasyonlarının nispeten yüksek olduğunu göstermektedir. Toprakların kirlilik sınıflandırmasına göre tehlikeli metaller içinde yer alan Cu ve Zn sınır değerleri aşmamıştır. Bitkilerde ise Fe hariç Mn, Cu ve Zn içerikleri sınır değerleri aşmamıştır.

In addition to having the most cultivation area and production in the world, cereals are irreplaceable in agriculture and in our life with being a basic food material. Wheat, which ranks first in terms of sowing area, is also an origin of our country and has been a basic food raw material since the beginning of history. Besides, wheat contains starch, protein, phytochemical and antioxidant substances which have an important role in human nutrition. As agricultural fertilizers, pesticides and herbicides have negative effects on the environment and human health, the interest in organic agriculture is increasing. The suspicion that pesticide, synthetic fertilizer and growth regulator residues can lead to cancer and other health problems in humans has led the researchers to focus their attention to improve of production methods that will prevent these disadvantages. Research has shown that the most reliable method of production is called Organic or Ecological or Biological Agriculture method. For these reasons, organic agriculture practices in the world have increased in the last 15 years. New breeding varieties selected in high-yielding traditional farming conditions do not sufficiently adapt to organic farming conditions. Readily available existing varieties due to yet correspond to new breeding for organic farming conditions not only yield when used in organic farming but also that they contain proteins and other useful in amounts of vitamins components also occurs a decrease. Cultivation of local varieties is becoming more attractive instead of already cultivated in marginal areas and stable yield values. For this purpose, local varieties produced in restricted regions of our country are the most suitable candidates for both breeding and organic production since they are well adapted to the regions where they are located.
