Considering morphometric traits, the tongue length, the length and width of the wings and basitarses were measured. In field conditions, scouts and forager bees were counted, the total amount of foraged pollen and the amount of foraged alfalfa pollen were measured. It was found that there is a very strong correlation between the amount of foraged pollen and the observed traits that determine the foraging activity of the honey bee, as well as the size of the basitarus at a statistically very significant level (p <0.01). There was a strong correlation between the traits that determine the foraging activity with each other (p <0.01). The size of the basitarsus (length and width) was strongly correlated with most traits. The wing length was in medium correlation with most traits (r = 0.3-0.6), while the wing width with all traits was weakly or negatively correlated. The length of the proboscis was in the medium strong correlation with most of the observed traits. It is weakly correlated with the width of the basitarus and the wing, and weakly to negatively correlated with the wing length.Item Pre-sowing treatments with gibberellic acid in white clover(University of Banja Luka, Faculty of Agriculture, 2021-05-27) Tomić, Dalibor; Stevović, Vladeta; Madović, Milomirka; Đurović, V.; Marjanović, Miloš; Lazarević, Đorđe; Petrović, Mirjana; Knežević, JsminaThe aim of this study was to analyze the effect of pre-sowing treatments with different concentrations of gibberellic acid solution, as a growth stimulator, on root and stem growth, seedling weight and nodulation of young white clover plants. The experiment was performed in 2019 in the laboratory for seed seed control at the Faculty of Agriculture in Čačak. Seed of rivendel cultivar were used. Six treatments with gibberellic acid were applied (control, 0.25; 0.5; 0.75; 1.0 and 1.5 mmol L-1 gibberellic acid). Root length, stem length and seedling weight were evaluated. Seedlings from the parallel experiment were planted in containers with substrate and cultivate in the greenhouse.Plants were analyzed 45 days after treatment. The obtained results indicate that pre-sowing treatments with gibberellic acid at a concentration of 1 and 1.5 mmol L-1 can significantly affect more intensive growth of plants of white clover.Item Suitability of field pea:oat and common vetch:oat mixtures for ensiling(University of East Sarajevo, Faculty of Agriculture, Republic of Srpska, Bosnia, 2021-10-07) Marković, Jordan; Vasić, T.; Petrović, Mirjana; Milenković, Jasmina; Bekčić, Filip; Lazarević, Đorđe; Babić, SnežanaThe practice of preserving green crops by fermentation as silage has increased dramatically in recent years. Successful ensiling can be difficult due to numerous problems such as: high moisture content, high feed buffer capacity, insufficient amount of fermentable carbohydrates etc. The aim of this investigation was to determine the suitability for ensiling field pea:oat and common vetch:oat mixtures grown at different seeding rate and harvested at different stages of growth. Field pea, common vetch and oat were grown in pure stands and in the mixtures of 75:25, 50:50 and 25:75 ratios and harvested at three stages of plant development: beginning of field pea and common vetch flowering, forming the first pods in field pea and common vetch and at the forming green seeds in 2/3 field pea and common vetch pods. The most favorable ratio of sugar and buffer capacity for the established level of dry matter in the examined crops was stated in pure oat crop. The results obtained in the mixtures of field pea and oat are based on the ratioof sugar and buffer capacity and can successfully ensile in all three examined relations of germinating grains of field pea and oats. The highest sugar content (182.1 g kg-1 DM) and the highest buffer capacity were determined in the 50:50 field pea:oat mixture at the pea flowering stage of development. The least favorable ratio of sugar and buffer capacity was found in pure common vetch.Item Stability of wheat cultivars for yield and quality components in different agroecological conditions(University of East Sarajevo, Faculty of Agriculture, Republic of Srpska, Bosnia, 2021-10-07) Luković, K.; Perišić, V.; Zečević, V.; Bratković, K.; Milovanović, M.; Babić, Snežana; Andjelković, SnežanaStability of grain yield, 1000 kernel weight and sedimentation value were analyzed in 10 winter wheat cultivars (Perfekta, Toplica, KG-52/3, Merkur, Vizeljka, Talas, NS 40S, Zvezdana, Javorka and Pobeda), created in different breeding institutions in Serbia. The experiment was carried out during 2019/2020 in two localities: Centre for Small Grains in Kragujevac and Institute for Forage Crops in Kruševac, Serbia. The analyses of variance showed highly significant differences in grain yield, between genotypes, investigated localities, as well as their interaction. The influence of the locality did not show statistical significance on the expression of 1000 kernel weight and sedimentation value. The highest average values were recorded by Perfekta for grain yield, Zvezdana for 1000 kernel weight and KG-52/3 for sedimentation value at both localities. The AMMI model was used for analysis of genotype × environment interaction. The most stabile cultivars were Vizeljka, NS 40S and Perfekta with values above the average for grain yield. Cultivars Talas, KG-52/3 and Javorka showed the highest stability for the 1000 kernel weight. Cultivar Javorka had the highest, while Talas and KG-52/3 had the lowest average values for this trait. Vizeljka and KG-52/3 were the most stable genotypes for sedimentation value, with KG-52/3 achieving the highest values of the observed trait at the level of the entire experiment. Both analyzed locations had high interaction value for all three analyzed traits.Item The effect of actinomycetes application on green mass yield of red clover(University of East Sarajevo, Faculty of Agriculture, Republic of Srpska, Bosnia, 2021-10-07) Andjelković, Snežana; Lugić, Zoran; Babić, Snežana; Milenković, Jasmina; Jevtić, Goran; Marković, Jordan; Bekčić, FilipRed clover (Trifolium pratense L.) is one of the most important and widespread leguminous forage species in temperate agriculture, which is characterized by a high yield of quality biomass. Actinomycetes produce antibiotics and vitamins that act favourably on physiological processes in plants. These microorganisms are present in the soil, however the application of selected microorganisms for seed inoculation leads to better results in crop production. The experiment was carried out in vegetation pots in semi-controlled conditions. This research consisted of investigating the effect of actinomycetes (Streptomyces sp.) application on the green mass per plants of 12 cultivars of red clover of different geographical origin: K-27, K-32, K-38, K-39, Una, Kolubara, Viglana, Manuela, Wilo, Repio, Diana and Longevo. The effect of inoculation was determined out at the onset of flowering. The results obtained showed that the application of microorganisms could affect plant mass yield. The highest value for green mass per plant was achieved in cv. K-39 using inoculum that contained Streptomyces sp. The application of actinomycetes had a positive effect in the most cultivars of red clover and there was a statistically significant difference between inoculated treatments and control, indicating the justification of the use of these microorganisms in plant production.Item Analysis of the relationship of the most important traits in meadow fescue(University of East Sarajevo, Faculty of Agriculture, Republic of Srpska, Bosnia, 2021-10-07) Babić, Snežana; Sokolović, Dejan; Andjelković, Snežana; Petrović, Mirjana; Zornic, Vladimir; Prijović, Mladen; Bekčić, FilipMeadow fescue (Festuca pratensis Huds.) is one of the most important perennial grasses foranimal feed production on grasslands. It is characterized by high and stabile yield potential andgood biomass quality. The aim of this study was to determine genetic and phenotypic correlation coefficients of seven most important traits of two synthetic cultivars (Kruševački 21 and Pradel). Individual plants for hybridization, in order to obtain progeny by the method of Comstock and Robinson, were selected completely randomly. In order to examine the obtained progeny, the study was performed in an experimental field of the Institute for Forage Crops, in two replications. The experiment was set up according to the Nested Design I, with sets within the replications. In Kruševački 21, 60 full-sib progeny were studied in two sets, while in the Pradel a total of 39 full-sib progeny were studied. Within each full-sib progeny, 60 plants were analyzed. Statistically and high statistically relation was obtained between some traits and presented as genetic (rg) and phenotypic (rf) correlation coefficients. In cultivar K-21 very high statistically significant genetic correlation coefficients were determined between heading date and leaf length (rg=0.873**), plant height and number of generative tillers per plant (rg=0.893**) and dry matter yield in the first cut and annual dry matter yield (rg=0.988**). In cultivar Pradel very high statistically significant relationship was obtained between heading date and plant height (rg=0.978**), heading date and number of vegetative tillers per plant (rg=0.926**) and annual dry matter yield with one side, and plant height (rg=0.912**) and dry matter yield in the first cut (rg=0.978**), on the other side.Item Alfalfa and red clover as a protein source for ruminants(Institute for Animal Husbandry, Belgrade-Zemun, Serbia, 2021-10-06) Marković, Jordan; Milenković, Jasmina; Andjelković, SnežanaHigh level of milk protein, increased dietary costs, as well as care for the environment have made nitrogen utilization a central component in balancing ruminant meals. Excess crude protein in meals can lead to unnecessary dietary costs, without resulting in increased milk and milk protein production. In addition, most of the excess nitrogen is excreted in the urine and is an ecologically labile form. On the other hand, poor amino acids balance will limit milk protein yield, making production more expensive than overeating. Balancing protein according to metabolic needs, with an adequate ratio of rumen undegradable protein and rumen degradable protein, and without overeating will have positive effects not only on meal price and profitability, but also on the environment. More efficient utilization of nutrients requires knowledge of how different fractions of nutrients pass through the digestive tract. Grass and legumes contain the largest and most variable part of non-protein nitrogen compounds. Although, a number of non-protein nitrogen compounds and true protein together represent crude protein, it is clear that the nutritional value of crude protein in ruminant feeds is better explained based on their rate and extent of rumen degradation. There are a number of factors that affect the amount of crude protein that will be degraded in the rumen. Legumes are high quality forages rich in protein, but these proteins are intensively degraded in the rumen. Red clover proteins are more slowly degraded than alfalfa protein.Item Effect of processing on vitamin C content, total phenols and antioxidative activity of organically grown red beetroot ('Beta vulgaris' ssp. 'Rubra')(Centre for Evaluation in Education and Science (CEON/CEES), 2021) Pavlović, Nenad; Mladenović, Jelena; Stevović, Vladeta; Bošković-Rakočević, Ljiljana; Moravčević, Đorđe; Poštić, Dobrivoj; Zdravković, JasminaThe demand for organic food is rising since consumers want food from reliable, highest quality sources originating from the environment, undisturbed by cultivation and processing. It is necessary to determine to what extent there is a scientific basis for the claims that organic food is of high quality. In this study, beetroot from an organic production system originating from 6 certified organic food producers from different geographic locations was examined. The organic beetroot samples were processed by pasteurization at 70 ºC and 90 ºC into beet juice or by drying at 55 ºC. The following samples were tested and compared: fresh beetroot, pasteurized beet juice and dried beetroot slices. The concentration of vitamin C, level of total phenol compounds (TPC) and antioxidative activity (TAA) in beetroot were influenced by the geographic origin and the applied processing method. The highest degradation for all analysed parameters was found in the samples treated by drying or pasteurisation at 90 ºC. The lowest losses of studied phytochemical components were observed during juice pasteurisation at 70 ºC. The correlation coefficient between TPC and TAA was high and significant (r2 = 0.966).Item Autochthonous plant growth-promoting rhizobacteria enhance Thymus vulgaris growth in well-watered and drought-stressed conditions(Lithuanian Research Centre for Agriculture and Forestry, 2021-12-06) Stamenov; Djuric; Hajnal-Jafari; Andjelković, SnežanaThe use of plant growth-promoting rhizobacteria (PGPR) in the production of medicinal plants is crucial, because agricultural chemicals are no longer acceptable in their production. This paper discusses the results of a recent study undertaken to isolate and characterize PGPR isolates of Bacillus, Pseudomonas and Azotobacter from common thyme (Thymus vulgaris L.) rhizospheric soil and monitor the effect of their application on seed germination and plant growth. The effect of selected isolates on seed germination and initial growth of common thyme was examined in controlled conditions. The impact of the isolates on the content of biochemical stress markers (total phenols and lipid peroxidation intensity) in germinated seeds was determined. The influence of the isolates on the plant growth under well-watered conditions (watered to 80% of water holding capacity (WHC)) and under water deficit stress (watered to 40% of WHC) was evaluated by measuring plant root and stem length in semi-controlled conditions. This study confirmed that indigenous rhizospheric bacteria of common thyme have multiple plant growth-promoting (PGP) properties. Among Bacillus 10 isolates, Pseudomonas 12 isolates and Azotobacter 9 isolates, only Pseudomonas isolate (P53) had all the tested PGP properties. The applied isolates had a positive effect on the examined plant growth parameters. The highest percentage of germination was determined in the treatment with P53 isolate (96%). The highest response for vigour index was observed with isolate A1 (3807%). All isolates, except B58 and B60, reduced stress by lowering the amount of both or at least one stress related molecules. The results of the experiment led to the conclusion that isolates Azotobacter sp. A1 and Pseudomonas sp. P53, both ACC-deaminase-producing bacteria, have the best effect on plant growth under well-watered and drought-stressed conditions, which indicates their potential to be used as a biofertiliser for promoting common thyme growth.Item Protein and carbohydrate fractions of common vetch-oat mixtures depending on stage of growth and seeding rate in the mixtures(Pensoft Publishers, 2020-11-08) Marković, Jordan; Vasić, Tanja; Terzić, Dragan; Štrbanović, Ratibor; Knežević, Jasmina; Blagojević, Milomir; Lazarević, ĐorđeThe production and utilization of intercropped legume- cereal bi-crops as ruminant feeds is beneficial for many reasons – legumes are rich in terms of protein concentration, whereas cereals are characterized by higher carbohydrate contents. To improve utilization of common vetch-oat mixtures as feed in Serbia, the objective of this investigation was to evaluate the crude protein (CP) and carbohydrate (CHO) fractions in these feeds using the Cornell Net Carbohydrate and Protein System (CNCPS) depending on the stage of plant development and seeding rate of common vetch and oat in the mixtures. The experiment was conducted at the experimental field of Institute for forage crops, Kruševac – Serbia, in 2015. The field trial was arranged in a randomized block design with three replications. In this research, pure stands of common vetch and oat, and their seed mixtures (common vetch:oat – 1:1.5; 1:1 and 1:0.5) were studied harvested at three different cutting stages: beginning of vetch flowering – 10% of flowering; forming the first pods on 2/3 vetch plants and forming green seeds in 2/3 pods. The samples were analyzed for protein and carbohydrate fractions according to CNCPS. Stage of growth affected significantly all carbohydrate and protein fractions, except unavailable PC fraction of crude protein which did not change with plant growth and development. The highest protein fraction was intermediately degraded PB2 fraction of crude protein. The highest carbohydrate fraction was available cell wall – CB3 fraction of carbohydrate. According to the results obtained in these investigations, it was concluded that common vetch-oat mixtures varied significantly with respect to their carbohydrate and protein fraction. Due to lower CC fraction, oat was superior feed in terms of total carbohydrates supply to ruminants. Among all investigated mixtures and pure stand of oat and common vetch, it could be conclude that mixture with 1:1 common vetch-oat rate was superior because of higher CA and CB3 fractions of total carbohydrate and the highest PB2 fraction of crude protein.Item Isoflavones of the red and Hungarian clover and possible impact on animal diet(Czech Academy of Agricultural Sciences, 2021-06-29) Petrović, Mirjana; Sokolović, Dejan; Babić, Snežana; Vymyslický, T.; Marković, Jordan; Zornic, Vladimir; Dajić-Stevanović, ZoraThe content of daidzein, genistein, formononetin, and biochanin A isoflavones was studied in natural populations of red and Hungarian clover, to estimate their impact on fodder quality and to determine directions in possible breeding programs. The study included 6 red clover (Trifolium pratense) and 6 Hungarian clover (Trifolium pannonicum) populations, collected in the central Balkans. The differences between the species and among the populations were analysed. The average content of total isoflavones was 1.393 mg g-1 and 0.487 mg g-1 of air dry matter in Hungarian clover, respectively. While the most prevailed isoflavone in red clover was biochanin A (46%), the Hungarian clover populations were rich in genistein (43%). The red clover leaves accumulated the highest content of isoflavones. The Hungarian clover flowers and leaves had an equal amount of isoflavones. The obtained values of the total isoflavones could not affect the overall nutrient quality and therefore, researched natural populations of two clover species could be considered for further breeding programs.Item Amelioration of thermal stress in crops by plant growth-promoting rhizobacteria(Elsevier BV, 2021-08) Mitra; Díaz Rodríguez; Parra Cota; Khoshru; Panneerselvam; Moradi; Sagarika; Andjelković, Snežana; Santos-Villalobos; Das MohapatraCrops are affected by various types of abiotic stress, resulting in a decrease in agricultural productivity thereby challenging food-security issues. Among the different types of abiotic stresses, the temperature has been regarded as a major one followed by salt and drought stress. The increasing temperature causes an alteration in the period of growth and the distribution of crop plants. High-temperature also damages the membrane, some proteins, inactivate the main enzymes and disturb the synthesis of biomolecules. Moreover, heat stress has been found to restrict the process of cell division as well. On the other hand, low-temperature is the main determinant of freezing which results in the reduction of plant cellular metabolism. Freezing stress forms ice-crystals in the cells that further leads to cell death due to dehydration and leakage of electrolyte. Generally, the stress tolerance in crops has been determined based on the cultivar's ability to withstand freezing temperatures; however, with advancements in microbiological techniques, several stress-tolerant microbes have been identified which either through direct or indirect mechanisms alleviate temperature-stress in plants. Furthermore, the function of cryoprotectant compounds and their signaling mechanisms in plants have been also discussed in detail for signifying their role in the alleviation of cold stress in plants. This review highlights the responses of plant growth-promoting rhizobacteria (PGPR) that are metabolically active under thermal stress conditions, and result in the production of metabolites that promotes plant growth and facilitate the uptake of nutrients under thermal stress in agro-ecosystems.Item Biomass and Protein Yields of Field Peas and Oats Intercrop Affected by Sowing Norms and Nitrogen Fertilizer at Two Different Stages of Growth(MDPI AG, 2021-09-10) Krga; Simić; Dželetović; Babić, Snežana; Katanski; Nikolić; DamnjanovićIn limited growing conditions, intercropped field peas and oats can represent a significant source of forage rich in protein. If applied correctly, factors such as nitrogen fertilizer, the mowing phase, and sowing norms can significantly increase the productivity of these mixtures. Field trials were conducted to examine their productivity under different nitrogen levels (0, 40, 80 kg ha−1), different sowing norms/mixtures (field peas: oats—100:15%; 100:30%), and two stages of growth (full flowering, full pod formation). Nitrogen fertilizer and different sowing norms had a significant effect on the biomass, hay, and crude protein yields. On average, the highest hay yields were achieved with 80 kg ha−1 N (4.96 t ha−1), followed by 40 kg ha−1 N (4.27 t ha−1). The highest protein yields were achieved with 40 kg ha−1 N (CP—704.1 kg ha−1), followed by 80 kg ha−1 N (CP—637.6 kg ha−1). Sowing norm 100:30% achieved higher hay yields: 100:30%—4.82 t ha−1; 100:15%—4.44 t ha−1, while 100:15% achieved higher crude protein yields: 100:15%—730.4 kg ha−1; 100:30%—692.7 kg ha−1 on average. The costs were not significantly increased with the nitrogen fertilizer, but the net profits were increased by as much as 163%, depending on the nitrogen level and the mixture. Nitrogen fertilizer also achieves higher economic efficiency for the mixture 100:15% compared to the 100:30% mixture. Mixtures of field peas and oats outperform single-grown crops and provide cost-effective feed for a short time. Using optimal seed ratios and nitrogen fertilizer can significantly increase the productivity and profitability of the feed with minimal impact on the overall production costs.Item Bioinformatics’ role in studying microbe-mediated biotic and abiotic stress tolerance.(Woodhead Publishing (Elsevier), 2021) Mitra, D.; Chaudhary, P.; Vermac, D.; Khoshrud, B.; Senapati, A.; Mahakur, B.; Panneerselvame, P.; Das Mohapatra, P.K.; Andjelković, SnežanaStress mitigation strategies present in plants alleviate stress caused by biotic and abiotic factors. In the current era, multi-omics approaches involving genomics, transcriptomics, proteomics, and metabolomics have expanded the horizon of molecular events participating in response to environmental and edaphic mediated stresses. The vigilant amalgamation of these approaches have supported a high level of information generated about root-level mechanisms involved in the alleviation of different plant-stress. Different bioinformatics tools provide a way in which huge amount of data are interpreted in a better form. This combination of multi-omics and bioinformatics approaches increases the genetic knowledge of researchers to improve the plant varieties in respect to their stress tolerance potential. Here, we provide an overview of bioinformatics resources, describing collections from multi-omics approaches, ranging from raw-data to complete databases, particularly highlighting those tools which have been used for answering the long-standing questions in the field of biotic and abiotic stress research.Item Penicillium crustosum - проузроковач плаве трулежи плодова нектарине(Društvo za zaštitu bilja Srbije, 2022-11-28) Bekčić, Filip; Vico, I.; Vučković, N.; Mikić, S.; Stepić, Marija; Andjelković, Snežana; Duduk, NatasaItem Специфичности производње различитих категорија сертификованог семена стрних жита у Републици Србији(Institut za povrtarstvo Smederevska Palanka, 2022) Perišić, Vladimir; Perišić, Vesna; Luković, Kristina; Bratković, Kamenko; Babić, SnežanaU proizvodnji atestiranih količina semena strnih žita u Republici Srbiji primetno je da se koriste veće proizvodne površine u Vojvodini u tu svrhu, kao i dominantan položaj stranih sorti kod pšenice i ječma, dok je kod tritikalea i ovsa obrnut slučaj.Item Утицај инокулације на квалитет ферментације и хемијски састав силаже луцерке(Faculty of Agronomy in Čačak, University of Kragujevac,, 2022-03-25) Lazarević, Đorđe; Stevović, Vladeta; Radović, Jasmina; Tomić, Dalibor; Marković, Jordan; Prijović, Mladen; Zornic, VladimirU cilju procene uticaja inokulanta „BioStabil Plus“ na proces siliranja lucerke, analizirani su parametri kvaliteta fermentacije (pH, sadržaj sirćetne, buterne, mlečne kiseline, amonijačnog i vodorastvorljivog azota u ukupnom azotu) i hemijskog sastava silaže (sirovi proteini, sirova celuloza, sirove masti, bezazotne ekstraktivne materije i pepeo), kao i ocena kvaliteta silaže (DLG i Zelter). Biomasa lucerke u fazi početka cvetanja silirana je bez dodataka i sa dodatkom inokulanta. Dodavanjem inokulanta utvrđeno je sniženje pH vrednosti, povećana proizvodnja mlečne kiseline, smanjena proizvodnja sirćetne kiseline, uz povoljan odnos ovih kiselina (2-3:1). Unošenjem inokulanta ostvaren je poboljšan kvalitet fermentacije, čime je dobijena bolja očuvanost hranljivih materija što se posebno odnosi na sirove proteine, s obzirom da je primenom inokulanta takođe utvrđeno smanjenje sadržaja amonijačnog azota u odnosu na kontrolu (inokulacija - 12,28 % NH3-N/ΣN, kontrola – 17,42% NH3-N/ΣN). Opšti zaključak je da biomasi lucerke treba dodavati inokulante, u svrhu optimalne produkcije mlečne i sirćetne kiseline, kao i dobijanja veće hranljive vrednosti.Item Утицај минералних ђубрива на флористички састав и принос травне заједнице Festuco-nardetum strictae subalpinum(Agronomski fakultet u Čačku, 2022) Zornic, Vladimir; Petrović, Mirjana; Andjelković, Snežana; Babić, Snežana; Sokolović, Dejan; Lugić, Zoran; Marković, JordanCilj rada je ispitivanje uticaja različitih doza mineralnih đubriva na travnu zajednicu Festuco-Nardetum strictae subalpinum.
