The compost product, which is a biologically active substance, emerges as a result of microbial decomposition of organic materials under controlled conditions. This product, which is used for the improvement of soil structure and the development of agricultural products, also offers opportunities in terms of minimizing the damage caused by organic wastes to the environment. It is important to encourage efforts for compost production, especially in terms of both disposal and economic evaluation of wastes generated in animal production farms. Determining the most suitable location of a facility for the utilization of animal wastes as compost, which will be obtained from livestock enterprises scattered in different geographical areas, will be an essential study in terms of minimizing operating costs. For such a facility, it would be an appropriate approach to use multi-criteria decision making methods to choose among predetermined facility location alternatives. In this study, a total of 17 facility location alternatives with 83,163 cattle potential in Çorum province were ranked according to the criteria determined and weighted by means of SWARA method. The optimal ranking of 17 alternatives determined by K-Means clustering analysis was carried out by COPRAS and MAIRCA methods. According to the ranking results obtained from both methods, it was determined that cluster number 6 was in the first rank, cluster number 4 was in the second rank, and cluster number 3 was in the third rank.

In order to increase access to nutritious foods around the world, innovative technologies need to be developed and integrated into agricultural production systems. The new plant breeding techniques developed offer many advantages for making modifications in the plant genome. CRSPR/Cas9, one of the genome editing technologies, is an efficient system with high potential that allows the formation of target-oriented mutations in many agricultural products and allows the mutation of new and desired characters to be obtained through breeding programs without the use of foreign genetic elements. In this review, we have summarize the discovery, evalution, functionality, genome editing studies of plants and the strong potentials of CRSPR/Cas9 technology for plant breeding.

Son yıllarda gerek tarımsal ilaçların gerekse kimyasal gübrelerin bilinçsizce kullanımı bitkisel üretimde artışın yanında kalitesiz ve insan sağlığını tehdit edecek ürünlerin ortaya çıkmasına neden olmuştur. Söz konusu sorunlara karşı sürdürebilir tarım ve değişik tarım alternatifleri konusunda çalışmalara ihtiyaç olduğu görülmektedir. Bitkilerin farklı tarım uygulamaları altında en yaygın sorununun azot (N) kullanım şekli olduğu görülmektedir. Bitkinin N kullanım etkinliğinde, uygulanan gübrenin N dozu ve formunun önemli olduğu düşünülmektedir. Bu amaçla, sera koşullarında artan dozlarda (0 (kontrol), 100, 200, 400 ve 800 mg N kg-1) ve farklı formlarda (mineral, organik) N uygulamalarının buğday bitkisinin büyüme, yeşil aksamda klorofilin bir ifadesi olan SPAD değeri, yeşil aksam kuru madde verimi ve yeşil aksam N konsantrasyonu üzerine etkisi belirlenmiştir. Denemeden elde edilen bulgulara göre, N noksanlığından kaynaklı verim kayıplarının olduğu buna karşılık N uygulamasının söz konusu verim kayıplarının önüne geçtiği saptanmıştır. Azot uygulamasından kaynaklı verim artış oranları üzerine uygulanan N formunun da önemli olabildiği belirlenmiştir. Özellikle mineral gübre uygulamasında verim artış oranlarının %58 ile %87 arasında değiştiği buna karşılık organik kaynaklı gübre uygulamalarının verim değerlerinde kısmen düşüşe neden olduğu görülmüştür. Farklı formlardaki N uygulamaları, bitkinin yeşil aksam kuru madde veriminin aksine yeşil aksam N konsantrasyonunu arttırmıştır. Bu artışlarda, N uygulama dozunun önemli olduğu buna karşılık uygulanan gübre formunun önemli bir farklılık yaratmadığı belirlenmiştir. Sonuçlar genel olarak değerlendirildiğinde en etkin N uygulama dozunun 200 mg kg-1 olduğu, bunun dışında N formları içinde bitkinin büyümesinde ve N kullanım etkinliğinde en etkin formun organik kaynaklı gübre olduğu görülmüştür.

The study aimed to identify the major challenges that affect the market information system, assess the possible mechanism that would increase their speculative and bargaining capacity power and to explore feasible information system solutions. Data were collected with structured questionnaire from104 farmers of different market using clustered sampling techniques. Descriptive research design and mixed (qualitative and quantitative) research approach vis-à-vis value chain approach is applied and developed an intermediary driven value chain model that links farmers to the market as a way to improve the unidirectional, selectively beneficiary traditional system. Using nine criteria on the multitude of alternative information delivery mechanisms for small holding farmers, Interactive Voice Response based system is found to be of highly effective. Restructuring the market information by bringing the most important wholesalers in to the system, enhancing the functionalities of the market by creating localized price data and creating demand forecasting platform by distinguishing crops that continuously face marketing problems are suggested as short-term action while, increasing economies of scale in production and distribution by consolidating farmers’ cooperatives, encouraging the development of third-party logistics, investing on the physical agro-logistics infrastructure to support long-distance, high-volume agricultural product transportation modes as well as increasing the refrigerated storage capacity at wholesale markets to nurture cold chain technologies are very crucial tasks in the long run.

The study was conducted to assess consumers’ preference and willingness to pay for different pepper varieties in Osun State, Nigeria. The study used the major pepper types – Capsicum chinenses (Rodo), C. annum (Tatase), C. frutescens (Sombo) and C. pubescens (Bawa), being sold in the markets in Osun State, Nigeria. A multistage sampling technique was used to collect data from 100 respondents. The primary data collected were analysed using descriptive and inferential statistics. The study showed that consumers mostly preferred and were willing to pay more for C. chinenses (Rodo) than any other types of pepper. Household size, primary occupation, total household income, availability and meal-making ability of pepper were the factors that influenced consumers’ preference for the different varieties of pepper while the willingness to pay for pepper varieties by consumers was influenced by affordability, availability, taste and thickness. The study recommends that since availability and affordability influenced preference and willingness to pay for pepper varieties, policies should be aimed at increasing farmers’ production as this will ensure that pepper is readily available and affordable for consumers.

Land consolidation is a powerful and effective tool in solving the fragmentation problem of agricultural lands to form a larger, more rational and efficient land for the farmers. The benefits of land consolidation projects are providing access to parcels, efficient use of water resources, real location of parcels, and reducing the costs of irrigation and drainage projects. Although not sufficiently successful, the land consolidation projects in Turkey had been initiated in 1961. This study was aimed to measure and assess the knowledge, expectation and attitudes of farmers on the land consolidation project planned to be implemented for some villages in Artova District of Tokat Province, Turkey. The study was carried out in Taşpınar and Aşağı Güçlü villages which were included in the consolidation program. In these villages, 62 farmers were selected by proportional sampling method out of 175 producers registered in the Farmer Registration System (FRS) and, face to face questionnaires were carried out with them. The results indicated that the producers support the project primarily due to the convenience in irrigation and increasing the efficiency of mechanization. Chi-square analysis revealed that the problems caused by disadvantages of fragmented land structure, importance of land integrity and the experience on a previous consolidation project area are important for the producers supporting the land consolidation project.

Salmonella is known as one of the main factors of food-borne gastroenteritis, and with this feature, it poses a great risk in terms of public health and economic losses. It is estimated that of the approximately 94 million cases of salmonellosis occurring in the world each year (about 85 percent of these are food-borne), an average of 150,000 result in death. Current social trends highlight the important health benefits of fresh produce in our daily diet. As an irony; Uncooked consumption of fresh herbal products is increasingly identified as a source of transmission for pathogens of intestinal origin, and epidemics occurring in this way are spreading rapidly. Today, the frequency of anthropogenic pathogen outbreaks associated with fresh produce, spices, and nuts has surpassed those associated with foods of animal origin. Human pathogens in the production chain; It can be transferred to plant material by basic means such as the use of animal manure, contaminated irrigation water, biological vectors (insects and animals) and contaminated seeds. In the light of these data, many intestinal pathogens have been identified as phyllo sphere-associated bacteria. Despite all these findings, there are many unknowns on the persistence and infectivity of Salmonella in contaminated plant hosts. In this review article, the factors affecting the attachment, colonization and survival of Salmonella on plant surfaces, as well as the information on the infection processes that continue with the invasion of plant tissues are discussed in the light of contemporary literature data.

The study aims at determining the physicochemical, proximate composition and the total viable count of Staphylococcus aureus in ‘Nono’ and yoghurt samples in Kaduna, Nigeria.Three hundred and eighty-four (384) fermented milk samples (Nono and yoghurt) were obtained from different selling points and were evaluated for the occurrence of S. aureus. The physicochemical and proximate analyses (pH, total titratable acidity, moisture content, ash content, protein content, and fat content) were determined. The results of the analyses showed that Nono had pH range of 3.56-3.61, total titratable acidity: 0.71-1.72, moisture content: 82.23-83.87%, ash content: 0.30-0.31%, crude protein content: 1.50-1.61%, crude fat content: 0.35-0.38 %. For yoghurt, the pH ranged from 3.76 -3.82, total titratable acidity: 1.10 -1.15, moisture content: 77.76-80.06%, ash content: 0.68- 0.70%, crude protein content: 3.40-3.45% and crude fat content: 1.76-1.79% from all the study areas. One hundred and four of the total samples were contaminated with S. aureus. Out of the 104 isolates of S. aureus that were isolated and identified, 88 were coagulase positive S.aureus. The Microgen Staph ID kit (Oxoid) was used to further confirm the characteristics of the 60 isolates of the coagulase positive S. aureus. The kit confirmed 43 isolates as S. aureus, the results indicated the presence of S. aureus in the milk samples which is of public health importance, as this can contribute to food-borne intoxication which can lead to food poisoning. There is a need for proper pasteurisation of raw milk to help eradicate S. aureus infection before human consumption.
