In this study, the Brown Layer Pure Line that housing as individual cage system at the Poultry Research Institute in Ankara was used. Eggs obtained from 24, 28, 32, 36 and 40 weeks old eggs were collected 3 times a day in the morning (10:00), noon (12:00) and evening (15:00). On a total of 427 eggs; Shape Index (SI), Egg weight (YA, g), Albumen height (AY, mm), Roche scale (RS), Haugh unit (HB), Egg Quality Classes (YKS), Shell strength (KM, N) and Shell thickness (KK, Micron) features are emphasized and colour parameters (L*, a*, b*, Hue, Ch and ΔE) of egg shell were determined. The effect of oviposition time was found significant on the Shape index, Egg weight (g), Haugh unit and Shell thickness (micron) values. However, Albumen height (mm), Egg Quality, Roche scale and Shell strength (N) were not affected by oviposition time. Among the egg shell colour parameters, a*, b*, Hue and Chrome values were affected by the oviposition time, and the calculated difference was found to be statistically significant.

This study was aimed at identification and prevalence of potato soft rot and black leg disease agent in the potato production areas of Tokat province. In March-August 2018, 67 field surveys were carried out in Central, Turhal, Zile, Pazar, Erbaa, Niksar, Artova and Basciftlik districts of Tokat. The disease incidences were 0.25%, 0.33%, 0.31%, 0.5%, 1%, and 8% in Central, Erbaa, Niksar, Pazar, Turhal, and Zile district, respectively. In Artova and Basciftlik districts, no disease was encountered. The following tests, pectolytic activity on potato, gram reaction, catalase, oxidase, growth at 37°C and 39°C, salt tolerance, hypersensitivity reaction were applied to isolates obtained from diseased plant and tuber samples. In the PCR assay, 19 isolates were produced 434 bp product with Y1/Y2 primers specific to Pectobacterium spp., and 3 isolates were produced 420 bp product with ADE1/ADE2 primers specific to Dickeya spp. The isolates resulted positive with Y1/Y2 primers weren’t produced PCR product with ECA1/ECA2 primers specific to Pectobacterium atrosepticum. According to this, 19 isolates were identified as Pectobacterium carotovorum. With this study, the causal agent of potato blackleg and soft rot disease have been identified in the potato production areas of Tokat. Further studies will be conducted to determine the species and subspecies level of the pathogens using specific primers.

Anthocyanins, a major natural food colorant rich in mango powder, need considerable protection during processing and storage for better retention due to colour instability. The purpose of the study is to evaluate the stability of the anthocyanin’s extracts obtained from cabinet dried mango powder under different factors which could disrupted the anthocyanin pigments during processing. The factors are processing temperature and time (30°C, 60°C and 80°C for 10, 20 and 30 minutes each, respectively), storage conditions (room temperature, refrigerator temperature and freezing temperature), pH (2, 3, 4, 7 and 10), oxygen, influence of light, different extraction solvent (methanol, absolute ethanol, acidified ethanol (1%), and 50% KMS -Ethanol), sugar level (20%, 40%, and 60%). The intensity of the extracted colour was measured at wavelength 520 nm using UV-VIS spectrophotometer. The results can elucidate the increasing heating temperature and time, sugar content, and exposure to light is able to spoil the anthocyanin molecule. There was a proportional effect of pH and oxygen. The anthocyanin stability was found better in pH=10, acidified ethanol (1%) as extracting solvents, absence of light as processing condition and refrigeration temperature as storage temperature. Hence, these findings could be useful in the food industry to choose a proper processing condition for development of mango powders-based products for satisfying the consumer perception by retaining anthocyanin pigment.

This study aims to compare UV-C irradiation and conventional heat treatment to produce pasteurized onion juice used as a meat marinating agent. The process conditions maximizing the inactivation of target microorganism Escherichia coli K-12 were; 0.5 mm sample depth, 30 min irradiation, 7.5 mW/cm2 UV incident intensity for UV-C and, 74.5°C and 12 min for heat treatment. Except pH and non-enzymatic browning index, differences between physicochemical properties of raw, UV-C and heat-treated onion juices were significant. Springiness and chewiness of unmarinated beefsteaks were higher compared to the ones marinated with the fresh and pasteurized onion juice (UV-C and heat). Pasteurization of onion juice (UV-C and heat) did not significantly affect general liking scores compared to beefsteaks marinated in untreated onion juice.

İnsan sağlığı açısından başlıca hayvansal protein kaynaklarından olan kırmızı etin yeterli miktarda ve düzenli olarak tüketilmesi elzemdir. Türkiye’deki kişi başı kırmızı et tüketimi dünya ortalamasının oldukça altındadır. Bunun temel nedeni olarak sığır eti fiyatlarının yüksekliği ve sürekli bir artış eğiliminde olması gösterilmektedir. Ayrıca bu artış, enflasyon üzerinde de önemli baskı oluşturmaktadır. Bu çalışmanın amacı, sığır eti fiyatlarında izlenen artış eğiliminin enflasyon etkisinden arındırılarak üretici açısından değerlendirilmesi ve üretici düzeyinde et fiyatlarındaki artışa etki eden temel faktörlerin tespit edilerek, fiyatlarda istikrarın sağlanmasına yönelik çözüm önerileri geliştirilmesidir. Bu çerçevede, et fiyatlarındaki artışa neden olduğu düşünülen faktörler tespit edilmiş, girdi maliyetleri, ikame-rakip ürün fiyatları ve hayvancılık desteklerinin cari ve reel seyri analiz edilmiş ve sığır eti tüketici ve üretici fiyatları arasındaki ilişki düzeyi tespit edilmiştir. Analiz neticesinde sığır eti fiyatlarındaki artışın temel olarak, et üretiminin yetersiz olması nedeniyle oluşan talebin karşılanamamasından kaynaklandığı ve süt fiyatları ile sığır eti üretici fiyatları arasında kuvvetli bağlantı bulunduğu saptanmıştır. Buna göre, kırmızı et fiyatlarında istikrarın sağlanması için öncelikli olarak et üretiminin artırılması, buna yönelik olarak etçi tip besi hayvancılığının geliştirilmesi ve besi materyalinin yurtiçinde üretimi ile hayvan varlığının yeterli düzeye çıkarılması, pazarlama zincirinin kısaltılarak denetim altına alınması, hayvancılık politikalarının uzun vadeli ve planlı şekilde belirlenmesi ile et ve süt ilişkisi göz ardı edilmeden doğru ve etkin bir destek mekanizması oluşturulması gerekmektedir.

The widespread use of antibiotics often causes increase in the bacterial drugs resistance and causes many side effects in humans. Medical plants have antimicrobial effects against most pathogenic bacteria and can serve as harmless replacement to antibiotics. The aim of this study was to assess the antibacterial effect of five medicinal plant prevailed in Kurdistan region namely; Cinnamon (Cinnamomum cassia (L.) D.Don), Nigella (Nigella sativa L.), Allium (Allium hirtifolium Boiss.), Carrot (Daucus carota L.), and Fennel (Foeniculum vulgare Mill.) against pathogenic Gram positive bacteria (Staphylococcus aureus), and pathogenic Gram negative bacteria (Salmonella typhi and Escherichia coli). The evaluation of antibacterial activity for these plant extracts was carried out using agar-well diffusion method. Results showed that minimum inhibitory concentration (MIC) of A. hirtifolium against tested bacterial isolates were (25 mg/mL), the lowest MIC values for S. aureus were (25 mg/mL) observed with C. cassia, N. sativa and F. vulgare ethanolic extracts and the lowest MIC of D. carota against bacterial isolates were (50 mg/mL), Also, it was observed that S. aureus was more sensitive than S. typhi and E. coli to plant extracts. The ethanol plant extracts had potential antibacterial activities. However, further studies are required to identify the active compounds which could be used for the preparation of new antimicrobial agents and control the bacterial infectious diseases.

Turkey is one of the major garlic producing country in the world and the significant amount of Turkey’s production has been made using a garlic variety called Taşköprü garlic (Allium sativum L.) in Kastamonu, Turkey. In order to improve the quality of garlic production, a field experiment was conducted to evaluate the effects of different doses of leonardite organic fertilizer, mineral fertilizer NPK and the mixture of both the leonardite and NPK fertilizers on the soil properties and mean performances of different characters and yield production of Taşköprü garlic. The treatments were: the plots without leonardite and NPK fertilizers (Control), (2) 80 N kg ha-1 + 40 kg ha-1 P2O5 + 100 kg ha-1 K2O (MF), (3) 2.6 ton ha-1 leonardite (Leo1), (4) 6.9 ton ha-1 leonardite (Leo2), (5) 9.7 ton ha-1 leonardite (Leo3), (6) Leo1 + MF, (7) Leo2 + MF and Leo3 + MF. Most soil characteristics and the different characters and yield production of Taşköprü garlic statistically varied between the different fertilizer treatments. The plots with the Leo3MF application showed the highest soil organic C, N, P and K concentrations, and the SOCstock and TNstock, while it had the highest bulb weight, length, equatorial diameter, weight of cloves, width of cloves, length of cloves as well as bulb yield per decare. Of the soil properties, the garlic yield was strongly positively correlated with the soil N concentration, indicating that the applications of leonardite with the different doses or the mixture of leonardite with the mineral fertilizer were resulting in higher soil N concentration and thus having the greatest effect on the garlic yields.

In wheat cultivation, sowing frequency is one of the crucial agronomic applications affecting grain yield. The aim of the research was to determine the effects of application of different sowing frequency (350, 500, 650 and 800 seeds m-2) for bread wheat cultivars (Alpu 01, Atay 85, Bezostaja 1, Harmankaya 99, Sönmez 01 and Sultan 95) on yield and yield components. Trials was carried out in Transitional Zone Agricultural Research Institute Eskişehir central campus fields during at 2012-13 and 2013-14 crop seasons in irrigated and rain fed conditions with 3 replications in randomized complete blocks design. In this study, the factors such as grain yield, number of spike per square meter, spike length, number of grain per spike, weight of grain per spike and harvest index were examined in terms of sowing frequency applications and cultivars in both conditions. As a result, the maximum grain yield was obtained from 650 seeds m-2 in rainfed conditions and this value was obtained from the application 500 seeds m-2 in irrigated conditions. Harmankaya_99 variety reached the highest values in terms of grain yield in both conditions and followed this by Alpu01 variety. In both conditions spike length, number of grain per spike, weight of grain per spike and harvest index parameters decreased inversely with increasing sowing frequency, while the number of spike number per square meter increased in direct proportion to increased sowing frequency. In rainfed conditions while there was a positive correlation between the grain yield with number of spike per square meter and harvest index, there was negative correlation among grain yield with spike length, number of grain per spike and weight of grain per spike. There was found significant positive correlation between grain yield with spike length and harvest index in irrigated conditions.

This study was carried out in order to determine the effect of organic liquid fertilizer applications on grain yield, yield characteristics and some quality trait of wheat in different periods in organic agriculture trial area. The trial was conducted in four replications according to a split-plot design in randomized blocks in trial area of the vocational Akçakale high school during the 2016-2017 and 2017-2018 growing season. Şölen 2002 and Edessa wheat varieties and organic liquid fertilizer and barnyard manure were used as materials in the research. Organic liquid fertilizer was applied in five different periods such as control, tillering, beginning of the bolting, the end of the bolting and the hearing, provided that the dose remained the same. According to the results of the research, the highest values were obtained in the end of the bolting of Şölen-2002 variety in terms of grain yield and yield components (spike length, spikelet number, number of grains per spike, grain weight per spike, plant height, hectoliter weight and thousand kernel weight). According to the results of two years, the highest grain yield (530.43 kg/da-1) was obtained in the end of the bolting application of Şölen-2002 variety. Since the first year of the study was warmer and more drought than the second year, While the yield and yield components decreased, the quality characteristics (protein and dry gluten ratio) increased. Due to the temperatures, Edessa variety had higher protein and dry gluten ratios than Şölen-2002 variety.
