Considering that beekeepers usually do not have their own land plots rarely rely on external transporters and often rely on external land plots, we present a fully functional platform to pair beekeepers, transporters, and land plot owners. Two algorithms for calculating optimal mobile beekeeping routes are developed in order to increase honey yield and minimize transport costs. We show that the first algorithm, based on the mathematical model, creates optimal routes in order to transport and distribute beehives by a distributor, while minimizing transport costs. In addition, we consider an option for the case when beekeepers themselves want to handle the transport and use a single external land plot. We show that, for this case, the application of the second algorithm creates a \"good enough\" solution. This iterative algorithm routes beekeepers to the closest land plot that can handle their beehives. Furthermore, we present a fully functional Web platform that applies these algorithms, enabling beekeepers, transporters and land owners to register and use the platform in Serbia.","PeriodicalId":31632,"journal":{"name":"Acta Agriculturae Serbica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71194087","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}

Rivers and canals, as corridors connecting neighboring habitats, are known to exhibit high invasion levels. Consequently, the aim of this paper was to show which catchment areas, environmental factors and habitat types can be seen as predictors of the presence of this invasive species in the riparian areas of Serbia. Field research was carried out at 250 field sites, where the cover and abundance of P. oleracea, relevant environmental variables and habitat type were recorded. Redundancy analysis (RDA) and response curves fitted using a generalized linear model (GLM) were used to show the relation of the cover of P. oleracea and the following variables: catchment area, predominant bank material, elevation, and the total number of invasive species on site. A non-metric multidimensional scaling (NMDS) was used to group sites where P. oleracea was found, based on the values of its cover. In general, primarily the rivers in the northern, low-lying part of Serbia can be seen as important corridors of the spread of P. oleracea. Its dominance is especially associated with areas draining into the Danube and Sava rivers and field sites characterized by a high pressure of invasive plants. Of the total number of records, the highest number of invaded field sites was recorded along the Danube, Tisa and Zapadna Morava rivers. Regarding the environmental and habitat predictors, the results have shown that the abundance of P. oleracea is associated with gravelly and sandy banks and grassland habitat types, primarily anthropogenic herb stands.","PeriodicalId":31632,"journal":{"name":"Acta Agriculturae Serbica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71193518","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}

The aim of this study was to determine the potential difference in the contents of several nutrients/phytochemicals in organically and conventionally produced buckwheat grains. Buckwheat was sown in 2016 at a site in Nova Varoš. The experimental plot covered a surface area of 1 ha. The contents of the following nutrients and phytochemicals in buckwheat grains were determined: proteins, pigments (chlorophyll a, chlorophyll b, carotenoids), soluble sugars, starch, free and bound polyphenols and flavonoids, and phytosterols. In addition, the antioxidant properties of the grains were assessed using the ABTS •+ ((2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) test (ability to inhibit ABTS •+ radical cations). There was no statistically significant difference in the contents of proteins, chlorophyll a and free phenols or in regard to the % of antioxidant capacity. On the other hand, two different production methods caused differences in the other chemical parameters. In organic grains, higher contents of carotenoids (6.998 µg g-1 dry matter (DM)), soluble sugar (6.48 mg 100 g-1 DM), starch (2.46 mg 100 g-1 DM), bound polyphenols (1034.3 mg (FAE) kg kg-1 DM), free flavonoids (1094.7 mg (QE) kg-1 DM) and bound flavonoids (1087.2 mg (QE) kg-1 DM) were detected, while in conventional buckwheat grains, there were higher levels of chlorophyll b (24.16 µg g-1 DM) and phytosterols (185.15 mg kg-1 DM).

Also, it has health benefits, which is the reason for its been used for the prevention of diseases caused by oxidative stress for centuries in many countries. Honey has antibacterial and antioxidant properties, which are the result of the presence of enzymes and chemical and phytochemical components, where phenolic acids and flavonoids play a significant role. The aim of this study was to examine the physico-chemical parameters, antioxidant properties and antimicrobial activity of forest-meadow, acacia and sunflower honey from the Gruža and Požega areas (Republic of Serbia). The tested physico-chemical parameters were found to be within the values prescribed by the Legislation and the Codex Alimentarius Standard. The presence of HMF was not detected in the sample of forest-meadow honey, while the content in other samples (1.09 and 1.79 mg HMF kg-1) was significantly below the value laid down by regulations (40 mg HMF kg-1). Forest-meadow honey had the highest antioxidant activity (35.2%, 26.32%-ABTS and DPPH method, respectively) and the highest content of total phenolics (90.96±5.18 g GAE 100 g-1), while acacia honey exhibited the lowest values for antioxidant activity (11.76%-ABTS; 7.28%-DPPH) and total phenolics (15.75±0,66 g GAE 100 g-1).

Our study aimed to isolate β-casein from bovine milk under dissociative conditions by the electrophoretic technique using Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE) and optimize an immunochemical technique such as Mancini radial immunodiffusion in order to monitor the evolution of this milk protein during storage. For this purpose, a series of physicochemical and bacteriological analyses revealed conformity with international standards. This allowed us to use quality milk for more detailed studies of proteins, in particular β-casein, which was selected as a marker of milk protein quality. The total casein of mixed milk samples was isolated and then submitted to electrophoretic separation. Various combinations of acrylamide and bisacrylamide were used and the one corresponding to the ratio 8 g / 230 mg was retained. A total casein deposit of 833 µg provided an adequate b-casein concentration (300 µg) for consistent animal immunization. Thirty Wistar rats were subjected to an immunization protocol for 35 days. The obtained antisera were used to optimize the Mancini technique and to assay b-casein in our samples at different storage times ranging from 3 h to 69 h/+4°C. A decrease in b-casein content from 0.85 mg ml-1 to 0.32 mg ml-1 was detected. These results demonstrate the vulnerability of b-casein at low temperatures and provide information on the origin of milk and its application for dairy or cheese production. In addition, our study confirms the usefulness of immunochemical techniques such as the Mancini test in the determination of β-casein.","PeriodicalId":31632,"journal":{"name":"Acta Agriculturae Serbica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71194380","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}

The aim of this research was the assessment of the diversity of 46 red clover accessions based on morpho-productive traits. The traits were investigated according to the UPOV descriptors for red clover-number of internodes, number of branches, stem length, stem thickness, middle leaflet length, middle leaflet width, green matter yield and dry matter yield. The principal components analysis (PCA) explained 74% of the variance of the standardized data and showed relationships between 46 red clover accessions and eight morpho-productive traits, associations among traits and performance of accessions. Among the determined Euclidean distances, the smallest value was obtained for the accessions Rotra and Titus (0.048), the largest value was 1.099 for a pair of NCPGRU2 and Čortanovci accessions, and the average value was 0.380. Two clusters of 46 red clover accessions were separated in the dendrogram based upon UPGMA (Unweighted Pair-Group Method with Arithmetic mean) for eight morpho-productive traits. The first cluster included two subclusters, while the second cluster contained four subclusters. The grouping of the accessions from the red clover collection by the UPGMA cluster analysis can be linked to the geographical origin of the accessions: central and Southern Europe for three subclusters and northeastern Europe for one subcluster.","PeriodicalId":31632,"journal":{"name":"Acta Agriculturae Serbica","volume":"56 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71194146","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}

The research was conducted on the seeds of the sorghum variety NS Džin and sudangrass variety Srem. Distilled water and aqueous extracts of young willow branches (Salix matsudana) and mature banana fruits (Musa x paradisiaca) were used to prime the seeds. The seeds were primed for: 1 h, 3 h, 6 h, 12 h and 24 h. The results showed that priming sorghum and sudangrass seeds in aqueous extracts of young willow branches and mature banana fruits can have a positive effect on seed quality parameters: germination energy, germination, seedling length and vigor index. The greatest effect on germination energy and seed germination was achieved in sudangrass by using an aqueous extract of young willow branches. The increase was 9.30% and 9.20%, respectively. Priming sorghum seeds in aquatic extracts of mature banana fruits had the greatest effect on seedling length and vigor index. The increase was 36.86% and 40.33%, respectively. For all research parameters, priming for 3 h was the most effective. However, in addition to the positive effect, priming can also have a negative effect.
