Nowadays, due to some reasons, soil quality deteriorates, soil organic matter decreases, and plant growth is adversely affected such as damaging agricultural practices, unconscious pesticide and fertilizer use. There is also treatment sludge among the methods that will contribute to the soil. Sewage sludge, the inevitable by-product of municipal and other wastewater treatment plant operations, is a key issue in many countries due to its increasing volume and the impacts associated with its disposal. This environmentally hazardous treatment sludge can be significantly reduced by anaerobic digestion. However, the resulting gas and the residues from anaerobic digestion process need to be treated or stabilized. The use of sewage sludge in agriculture will provide both soil nutrient elements and waste sludge can be disposed with this application. Definitely, it is possible to evaluate the treatment sludges in many different areas. After cleaning the sludge from contaminants, it can be used as a good compost or soil improvement material. In this study, agricultural applications with sewage sludge were investigated.

Global warming, which has been increasing in recent years, is due to the increasing amount of greenhouse gases in the atmosphere. The agricultural sector, which has a 25% share in greenhouse gas formation, plays an important role in global warming. CO2, which has a share of 82% among greenhouse gases, is shown as the most important greenhouse gas. It is estimated that 10% of the CO2 in the atmosphere is missioned from the soil. When soil organic carbon, which is an indicator of soil fertility, is released into the atmosphere as CO2, N and S compound gases return to the earth and it causes inefficient soil as well as global warming. Organic carbon is a source of CO2 emissions when the soil is mismanaged. The organic carbon in the soil is transformed into CO2 with loosening of the soil and accumulates in the atmosphere, after it exposure to temperature and oxygen. Unconscious tillage and irrigations increase the physical and biological activity of the soil and cause CO2 emissions from the soil. CO2 emission, which is the main cause of drought, needs to be reduced with low cost, easy and practical applications. At the beginning of these applications, can be listed reduced tillage, deficit irrigation, reduction of fertilizer usage, reuse of agricultural wastes and agricultural management of wastewater. In this review, it is aimed to investigate CO2 emission effect of soil tillage depth and tools, exhaust gases of the vehicles used in soil tillage, the amount of irrigation water and irrigation methods, deficit irrigation, irrigation with wastewater, precipitation, plant factor, fertilization, properties and temperature of soil. In addition, approaches that can be applied to reduce CO2 emission are mentioned.

This study is consisted of data obtained from the survey conducted with 400 consumers in Uşak province urban area. As a result of the analysis, the average amount of annual per capita chicken meat consumed was calculated as 13.64 kg. The average amount of consumption increases due to the increase in income level. 39.2% of the consumers (consume chicken meat once a week. However, nearly half of consumers (41.7%) consume chicken meat, this is one third in total meat consumption. This ratio is changing according to income groups. Consumers supply chicken meat from vendors, grocery stores and groceries. The main reason for consumption of chicken meat for consumers; low price, easy to find on the market and healthy. Nearly half (42.5%) of the consumers prefer whole chick. The percentage of those consumed in the chicken meat consumed by the consumers is very low. Factors that are effective on consumers preferences for chicken meat; the freshness of the product, the price, the type of packaging, the quality, the producer company, the advertisement of the product, the taste of the consumer and the date of manufacture of the product. According to consumer preference (but, baguette, chest, wings etc.) processed products can be prepared according to the grill or other purposes and presented to the consumer. As consumers are prepared to extra payment for organic (ecological) food products, the farmers can be guided by incentives to organic poultry breeding systems.

Anoectochilus formosanus Hayata was demonstrated to have a benefit healthy due to containing active pharmaceutical ingredients. However, A. formosanus is usually processed to produce tea bags which would destroy the bioactive compounds because of the processing procedure. The aim of this study was to evaluate the influence of extracted methods including microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE), and fermentation by Lactobacillus acidophilus ATCC-4356 to extract the active pharmaceutical ingredients from A. formosanus. The extracted liquid was analyzed total phenolics, total polysaccharide, and antioxidant activity. The results showed that three methods have a positive effect on the extraction of bioactive compounds of A. formosanus in which the fermentation showed the best result. The total phenolic content, total polysaccharide content and antioxidant capacity that extracted by the fermentation method were 11.762 mg GAE/g; 48.914 mg GE/g, and 1.582 mgVit C/g compare to MAE and UAE which were 7.818 mg and 8.128 GAE/g samples; 41.22 and 37.91mg GE/g samples; 1.032 and 1.163 mgVit C/g respectively. The A. formosanus fermentation method by L. acidophilus promotes bioactive compounds of high biological value. This study would suggest a novel use of lactic fermenting A. formosanus in the production of functional foods.

The data in this study was provided from 400 households in the Kucukcekmece District of Istanbul Province in 2011. Unclustered Proportional Sampling Method was used to determine the sample size of the study. The primary objective of this study was to identify the most suitable type of milk for consumers. In determining the most appropriate type, four criteria were taken into account. These criteria are hygiene, shelf-life, nutritional content, and price. Based on the data, milk consumption was 30.2 L per annum per capita in Istanbul Province. The households consist of about 3.7 individuals, and they give importance to hygiene by 26.4 percent, shelf-life by 26.7 percent, nutritional content by 29.6 percent and price by 17.2 percent. 55.3 percent of the households prefer UHT (long of shelf-life Tetra Pac packaged milk which heat-treated range of 135-150°C in a short period of 2-4 seconds) milk, 28.5 percent prefer Pasteurized milk, and 16.2 percent prefer Raw milk. Also, while households gave more importance to price and nutrient content at the raw and pasteurized milk, shelf life and hygiene content at UHT milk. Considering these criteria, the most suitable type of milk for the consumers was UHT milk. As a result, the national companies marketing pasteurized milk in the research area need advertisement works that inform the consumers regarding pasteurized milk.

The aim of this study was to evaluate the clinic-histopathologic characteristics and to compare the morphometric measurements of healthy and subclinical laminitic claws of dairy cattle at different ages and weights. Non-lame 60 Holstein feet randomly collected from the slaughterhouse were evaluated. The effects of age, body-weight, claw location (right front lateal or right front medial etc), and presence of laminitis were investigated. The claws’ conformation were evaluated morphometrically with ten measurements (toe length, toe height, outer and inner edges of the claw, heel height, the length of heel, the length of diagonal front wall, dorsal hoof angle, the width and the length of the sole). The claws were classified as normal or laminitic according to the histopathologic findings. The clinical findings of laminitis was confirmed on 71.2% of the claws (n=66). The toe length, toe height, the height of outer and inner edges of the claw, heel height, the length of heel, the length of diagonal front wall were smaller in laminitic claws. The dorsal hoof angle of healthy claws were bigger and statistically significant than the laminitic claws. Small haemorrhagic areas were determined in the parietal corium in the laminitic claws comparing to macroscopically healthy claws. The histopathologic characteristics of the corium of laminitic claws involve the hyperaemia, haemorrhages, oedema, thrombosis of capillaries and presence of mononuclear cell infiltration in dermis, stretching epidermal lamella, necrosis of epithelial cells and detachment of the lamellar basement membrane. According to this study results, contrary to literature, there was not a reliable relation between some changes in morphological structure of the claws and the presence of the laminitis were observed.

Eggs are important components of the human diet due to their low cost, high protein content and protein related technological features. High digestibility of egg proteins makes it possible to consume alone in the assay of nutritive values. Binding, emulsifying, foaming, gelling, and thickening properties of egg proteins provide an opportunity to use egg in various food products as an ingredient. Therefore, the consumption of egg is increasing with each passing day, however, Salmonella enterica serovar Enteritidis and Salmonella Typhimirum infections have been reported to be egg-born. These serious infections are originated from direct consumption of eggs or unpasteurized food products in which the egg yolk/albumen is added to the formulations such as mayonnaise, salad dressings or merengues. In order to prevent these infections, aforementioned microorganisms must be eliminated from the environment by pasteurization. Commercial pasteurization process is applied with hot water or vapor. Commercial processes include high temperature/short time or low temperature/long-time pasteurization. Although heat treatment is considered the most reliable method in terms of microbiological safety, high temperature and/or long time applications may have adverse effects on functional and nutritional properties of egg proteins. To ensure the microbiological safety of products without sacrificing technological or nutritional properties, researches have been centered upon innovative techniques such as irradiation, pulsed electric field, high hydrostatic pressure, and radiofrequency applications. This review is aimed to bring out the amendments occurred in the egg protein structures in consequence of aforementioned pasteurization methods.

In this study, the effects of carvacrol addition which is a natural preservative to apple juice samples contaminated with Z. bailii which is an osmotolerant yeast and shows resistance against high sugar concentration, low acidity, ethanol content and pasteurization process, were investigated on some physicochemical and bioactive properties and also changes in yeast numbers during storage period. For this purpose, the response surface methodology was applied and storage time (1-41 days), storage temperature (4-20°C), sodium benzoate amount (0-0.1%) and carvacrol amount (0-750 ppm) were selected as processing variables. Significant changes in physicochemical properties were observed due to yeast viability occurred during the storage of apple juice samples. The increase in the amount of carvacrol caused a decrease in the number of yeasts about 7 log level and prevented the spoilage of fruit juices. However, the brix value of the samples without carvacrol showed a decrease of 50% as a result of yeast activity and the fruit juice could not be consumed. Total phenolic content of the sample was in the range of 136.7-645.7 mg GAE/L and the lowest total phenolic content was determined for the run 11 having no carvacrol while the highest total phenolic content was for the sample added with the highest carvacrol level. As a result of the optimization process, it was observed that the deterioration activities of Z. bailii could be prevented to a great extent by the addition of maximum amount of carvacrol.

The study aimed to evaluate the use of germination indices as a screening tool for salinity tolerance during germination and early seedling growth of pepper cultivars, and to distinguish the potential for genetic responses to salt tolerance. In the study, the seeds of seven pepper cultivars were germinated at increasing NaCl levels of 5, 10, 15 and 20 dS/m and distilled water as the control treatment for 14 days. Germination percentage (GP), mean germination time (MGT), germination index (GI), germination stress tolerance index (GSTI), seedling length (SL), seedling fresh weight (SFW) and vigor index (VI) were investigated. Results showed that germination percentage decreased with increasing NaCl levels while the highest germination percentage at 20 dS/m was 92% in BT Burdem with no significant reduction. Seedling growth of pepper cultivars was severely inhibited by increasing salinity stress. SFW was depressed depending on reduction in SL due to increasing NaCl. BT-Burli and BT İnce Sivri were the most tolerant cultivars to NaCl and they were used for genetic resources towards salinity. Seedling growth was much more sensitive to salinity than germination because of the highest percent reduction in seedling growth parameters. Among the parameters, GSTI gave the highest significant correlation coefficient with SL and SFW; indicating that it would be useful for estimating seedling growth. It was concluded that genotypic variation was observed among pepper cultivars for salinity tolerance and GSTI could be used for a predictor for salinity tolerance.
