The meat supply chain should be regularly monitored to ensure the safety of products. Recent developments in Artificial Intelligence, Internet of Things and blockchain technologies will have a tremendous and disruptive effect on the meat supply chain system in terms of improving the monitoring and surveillance of hazards at multiple points along the meat chain (pre-harvest, harvest, post-harvest), in the farm-to-retail continuum, as well as providing better quality of information to consumers for informed decisions regarding food purchase. The farm-to-fork food chain continuum should be managed to provide an appropriate level of consumer protection (ALOP). This can be achieved by science-based risk assessment, which includes information about the prevalence and concentration of major public health hazards (epidemiological indicators) of zoonotic origin (Salmonella, Campylobacter, Listeria monocytogenes, Yersinia, Shiga toxin-producing Escherichia coli/STEC) in all modules along the food (meat) chain: farm - transport - slaughterhouse - meat processing - distribution - retail - consumers. The integration of digital technologies to the Food (Meat) Safety Management System or Meat Safety Assurance System will enhance the integration of Food Chain Information and Harmonized Epidemiological Indicators along the meat chain, from farm to retail (bottom-up) and vice versa from retail to farm (top-down). Meat chain digitalization will also increase the transparency and visibility of all actors involved in meat production, processing, distribution and retail (farmers, meat business operators, competent authorities, retailers), and provide the basis for benchmarking producers and retail chains, as well as pro-active consumer participation in defining future food policies at the national and global level.

There is a significant amount of research in the world on the factors that influence consumers' decision to buy organic food using traditional sales channels. There is also a lot of research related to the factors that influence consumer decision to online shop groceries. However, to our knowledge, there is an extremely modest amount of research on how and why consumers decide to online shop organic food. The Covid-19 pandemic has led to an increase in consumer propensity to shop online, so this topic has gained in importance. Therefore, the aim of this paper was to determine the factors that most influenced consumers' decision to online shop organic food during the Covid-19 Pandemic. The survey was carried out in Serbia by using a questionnaire developed specifically for this purpose, based on questions from 9 relevant surveys in the world. Factor analysis and standard multiple regressions were used to analyze the data obtained from the survey. Four factors have been identified that influenced the online shopping organic food during the Covid-19 Pandemic. The first and most important factor is the Attributes of organic food and deterrents for purchasing. The second important factor is the advantages of online shopping, Covid-19 Pandemic consequences, and organic food labeling. While the third factor (Website characteristics and satisfaction with online shopping) and the fourth factor (Safety of online shopping) are of minor importance. At the end of the paper recommendations for improvement marketing strategy for online selling organic food are given.

The experiment with drip irrigated pepper was conducted at the Rimski Šančevi experimental field of the Institute of Field and Vegetable Crops in Novi Sad in 2019. The irrigation was scheduled on the basis of the water balance method. Two methods were used to compute the daily evapotranspiration of pepper (ETd): reference evapotranspiration (ETo) and evaporation from an open water surface (Eo). Crop coefficients (kc) and corrective coefficients (k) were used to convert ETo and Eo values into ETd. Kc and k were 0.3-0.4, 0.6-0.7, 0.9-1.1, 0.8-0.9 and 0.4, 0.7, 1.0 and 0.8 for initial stage, crop development, mid season, and late season, respectively. ETo was calculated by the Hargreaves equation. Eo values were measured by a Class-A pan located at a meteorological station near the experimental plot. Irrigation started when readily available water (RAW) in the 0.3 m soil layer was completely absorbed by plants. Differences in crop yield (Y) and irrigation water use efficiency (IWUE) obtained using Eo (42.58 t ha-1, 15.20 kg m-3) and ETo (40.78 t ha-1, 14.56 kg m-3) were not statistically different. Evapotranspiration rate was 364.2 mm and 337.3 mm in Eo and ETo variant, respectively. The fact that the differences in Y and IWUE between different calculations of ETd were not statistically significant indicates that both methods can be recommended for irrigation scheduling programs for pepper in the climatic conditions of the Vojvodina region. However, priority should be given to ETo due to the easy accessibility and reliability of data.
滴灌辣椒试验于2019年在诺维萨德大田和蔬菜作物研究所的Rimski Šančevi试验田进行。根据水量平衡法进行灌溉调度。采用参考蒸散发(ETo)和开放水面蒸散发(Eo)两种方法计算辣椒的日蒸散发。利用作物系数(kc)和校正系数(k)将ETo和Eo值转换为ETd。初熟期、作物生育期、季中、晚熟期的Kc和k值分别为0.3 ~ 0.4、0.6 ~ 0.7、0.9 ~ 1.1、0.8 ~ 0.9和0.4、0.7、1.0和0.8。ETo由哈格里夫斯方程计算。Eo值由设在试验田附近气象站的a类平底锅测量。当0.3 m土层的有效水分(RAW)被植物完全吸收后，开始灌溉。Eo (42.58 t ha-1, 15.20 kg m-3)和ETo (40.78 t ha-1, 14.56 kg m-3)处理的作物产量(Y)和灌溉水分利用效率(IWUE)差异无统计学意义。Eo和ETo变异的蒸散速率分别为364.2 mm和337.3 mm。不同ETd计算方法的Y值和IWUE值差异无统计学意义，说明在伏伊伏丁那地区的气候条件下，这两种方法都可以作为辣椒灌溉调度方案的推荐方法。然而，由于数据的易访问性和可靠性，应优先考虑ETo。

Plants are the most important source of Fe for humans and animals; therefore, its accumulation in edible plant parts is of great importance. Since plant species, ecotypes, genotypes, lines, and varieties may differ in their ability to accumulate mineral elements, the aim of this study was to i) examine the accumulation of Fe in the grain of Aegilops and Triticum species with different genomes (AA, BB, BBAA, BBAADD), ii) study the relationship between the level of ploidy and grain Fe accumulation, and iii) analyze correlations between grain size and Fe concentration. Twenty different genotypes were included in three-year field experiments. The examined species and genotypes differed significantly with respect to grain Fe concentration, which was the highest in diploid Aegilops speltoides (BB genome). Tetraploid and modern cultivated hexaploid varieties displayed substantial variation in Fe concentration in the whole grain. Genotypes also differed significantly in thousand grain weight (TGW), which was the smallest in Aegilops speltoides. A significant negative correlation was found between grain Fe concentration and TGW, and a positive correlation between TGW and Fe content in individual grains. The higher accumulation of Fe in individual grains of tetraploid and hexaploid wheat vs. diploid ancestors suggests that the increase in ploidy led to an increase in the capacity of grains to serve as a sink for that Fe. The results indicate that genetic diversity in the wheat genome is sufficient to allow a significant increase in Fe concentration in the wheat grain.

The situation with the virus Covide-19 worldwide, in addition to the many questions of how to best protect ourselves, drew the attention of people and professional community, to the significance and the importance that a healthy nutrition has in preserving and building up immunity, and thus also in the prevention and protect the organism from various negative agents. Due to increased consumer concern for their own health and the environment the organic food market is one of the fastest growing markets in the food industry. The main goal of the current research is to examine determinant factors influencing organic foods purchase in our region. The sample consisted of 571 subjects from Serbia and the region. The data were processed by the SPSS program, and the obtained results show that in our country, as well as anywhere in the world, the price is the most common barrier in the situation of buying organic food. Gender of our subjects was not a significant factor in making the decision and realization of the purchase, while their marital status and age had an influence in making the mentioned decision. In general, our research showed that younger respondents, who are not married, are the most common buyers of organic food.

The paper presents the cartographic processing of the Landsat TM image by the two unsupervised classification methods of SAGA GIS: ISODATA and K-means clustering. The approaches were tested and compared for land cover type mapping. Vegetation areas were detected and separated from other land cover types in the study area of southwestern Iceland. The number of clusters was set to ten classes. The processing of the satellite image by SAGA GIS was achieved using Imagery Classification tools in the Geoprocessing menu of SAGA GIS. Unsupervised classification performed effectively in the unlabeled pixels for the land cover types using machine learning in GIS. Following an iterative approach of clustering, the pixels were grouped in each step of the algorithm and the clusters were reassigned as centroids. The paper contributes to the technical development of the application of machine learning in cartography by demonstrating the effectiveness of SAGA GIS in remote sensing data processing applied for vegetation and environmental mapping.

Potato can be grown on a large number of soil types. In order to determine the suitability of leached soils for potato growing in Western Serbia, a trial was set up with the aim of observing agrophysical and agrochemical properties of this type of soil in the region of the Radočelo mountain massif in 2020. Three soil profiles were opened. Results pointed out that leached soils of Western Serbia are suitable for potato growing according to their agrophysical properties, but unfavourable as regards some agrochemical parameters (a low content of available phosphorus, high values of active, exchangeable, and hydrolytic acidity). Nevertheless, it is possible to achieve high yields that approach the biological potential of potato using appropriate soil amendment practices (timely application of proper amounts of the complex NPK fertiliser with increased phosphorus and potassium levels, basal liming of the soil along with manuring, and use of physiologically neutral nitrogen fertilisers).

Parameters of the head are among the most important characteristics of each dog breed. The first morphometric examination of hounds on the territory of Bosnia and Herzegovina was performed by Laska in 1905. Since then, no one has ever conducted morphometric measurements on the Bosnian broken-haired hound - Barak. The breed itself is recognized by the FCI, and described under standard No 155, 1973. As for the head, the standard only describes the length, with no other parameters. The aim of this paper was to determine the basic parameters of the head of the Bosnian broken-haired hound - Barak by conducting zootechnical measurements. The study involved 120 dogs, including 64 males and 56 females, aged from 9 months to 10 years, from the entire territory of Bosnia and Herzegovina. The total of five parameters of the head was measured on each dog, and four indexes were calculated based on these measurements. This paper is the first analysis of the morphometric characteristics of the head of the Bosnian broken-haired hound Barak, and the results can be used for further detailed description of this breed.

The improvement of wastewater treatment techniques is of crucial importance for effluent quality, but it also results in an increased amount of waste sludge. Dehydrated sludge contains organic matter and nutrients, and therefore it can be used in agriculture and bioremediation, but it is considered a potential source of environmental pollution. As the sludge analyzed in the research does not contain impermissible levels of organic and inorganic pollutants, the aim of the research was to examine microbiological, particularly sanitary, aspects and potential for its further use. Microbial diversity was determined by the standard serial dilution technique and selective media, and sanitary quality indicators (total coliforms, fecal coliforms, Escherichia coli and Salmonella spp.) were determined by the MPN method. The abundance of fungi, actinomycetes, and bacteria (ammonifiers, spore-forming bacteria and Pseudomonas spp.) indicate possibilities for further use of the sludge. The chemical analysis included the following parameters: total nitrogen (N), phosphorus in the form of P2O5 (available P), organic carbon (C), C/N ratio, pH, and water content. The chemical composition indicates the potential of sewage sludge to be used as a soil fertilizer, but its C/N ratio is not adequate to enable successful conversion to biosolids by the composting process. The obtained results indicate a significant level of microbiological contamination, which was most pronounced in the centre of the stabilized sludge pile. The research showed the necessity to conduct further studies on the microbial diversity and sanitary aspects of sewage sludge for proper waste sludge management.

As the sludge analyzed in the research does not contain impermissible levels of organic and inorganic pollutants, the aim of the research was to examine microbiological, particularly sanitary, aspects and potential for its further use. Microbial diversity was determined by the standard serial dilution technique and selective media, and sanitary quality indicators (total coliforms, fecal coliforms, Escherichia coli and Salmonella spp.) were determined by the MPN method. The abundance of fungi, actinomycetes, and bacteria (ammonifiers, spore-forming bacteria and Pseudomonas spp.) indicate possibilities for further use of the sludge. The chemical analysis included the following parameters: total nitrogen (N), phosphorus in the form of P2O5 (available P), organic carbon (C), C/N ratio, pH, and water content. The chemical composition indicates the potential of sewage sludge to be used as a soil fertilizer, but its C/N ratio is not adequate to enable successful conversion to biosolids by the composting process. The obtained results indicate a significant level of microbiological contamination, which was most pronounced in the centre of the stabilized sludge pile. The research showed the necessity to conduct further studies on the microbial diversity and sanitary aspects of sewage sludge for proper waste sludge management.","PeriodicalId":31632,"journal":{"name":"Acta Agriculturae Serbica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71193774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
