AB  - The objective of the present study was to investigate the susceptibility of maize hybrids to the natural occurrence of toxigenic fungal species, in particular toxigenic Aspergillus and Fusarium species, and mycotoxins (aflatoxin B1 (AFB1), deoxynivalenol (DON) and total fumonisins B1, B2 and B3 (FBs)). Grain samples of six commercial maize hybrids (MAS 34.B - FAO 300, MAS 40.F, MAS 48.L, KWS Konfites and ZP 427 - FAO 400, and MAS 56.A - FAO 500) were collected at harvest in 2018. A total of seven fungal genera, Acremonium, Alternaria, Epicoccum, Fusarium, Nigrospora, Penicillium and Rhizopus, were identified of which only species from the genus Fusarium were present on maize grains of all hybrids tested. The incidence of Fusarium spp. was higher in the hybrids MAS 48.L (54.6%), and MAS 56.A (53.3%), compared to MAS 40.F (37.3%), KWS Konfites (28%), MAS 34.B (22.6%) and ZP 427 (12%) hybrids. Among the identified Fusarium species (F. graminearum, F. proliferatum, F. subglutinans and F. verticillioides), F. proliferatum was present in all hybrids, ranging from 9.3% (ZP 427) to 30.7% (MAS 48.L ), whereas F. subglutinans was present in two hybrids, MAS 40.F (16%) and MAS 56.A (9.3%). The incidence of F. graminearum ranged from 0% (KWS Konfites) to 9.3% (MAS 34.B), while the incidence of F. verticillioides ranged from 0% (MAS 34.B and ZP 427) to 21.3% (MAS 48.L). In the samples, Aspergillus species were not identified. The effect of maize hybrids was significant on the level of mycotoxins. MAS 34.B hybrid had a statistically significantly higher levels of AFB1 and DON than other hybrids. The FBs level was the highest in the hybrid MAS 34.B (1202 mg kg-1 ) and the lowest in the hybrid KWS Konfites (88.33 mg kg-1 ). However, the FBs level did not differ between hybrids MAS 34.B, MAS 40.F, and MAS 56.L, MAS 40.F, MAS 48.L, and MAS 56.A, and KWS Konfites and ZP 427. In all hybrids, AFB1, DON, and FBs levels were below the maximum permissible levels stipulated by the legislation of the European Union and the Republic of Serbia in unprocessed maize. The agro-ecological conditions in 2018 favored the development of Fusarium species on maize grains of the hybrids tested, especially fumonisin producing species.
AB  - Cilj rada je bio da se ispita osetljivost razliĉitih hibrida kukuruza na prirodnu pojavu toksigenih vrsta gljiva, posebno toksigenih Aspergillus i Fusarium vrsta, i mikotoksina (aflatoksina B1 (AFB1), deoksinivalenola (DON) i ukupnih fumonizina B1, B2 i B3 (FBs)). Uzorci zrna šest komercijalnih hibrida kukuruza (MAS 34.B - FAO 300, MAS 40.F, MAS 48.L, KWS Konfites i ZP 427 - FAO 400 i i MAS 56.A - FAO 500) sakupljeni su u vreme berbe 2018. godine. Analizom mikobiota identifikovane su vrste iz sedam rodova, Acremonium, Alternaria, Epicoccum, Fusarium, Nigrospora, Penicillium i Rhizopus, od kojih su samo vrste iz roda Fusarium bile prisutne na zrnu kukuruza svih ispitivanih hibrida. Veća uĉestalost Fusarium spp. na zrnu kukuruza bila je kod hibrida MAS 48.L (54,6%) i MAS 56.A (53,3%) u poreĊenju sa hibridima MAS 40.F (37,3%), KWS Konfites (28%), MAS 34.B (22,6%) i ZP 427 (12%). MeĊu identifikovanim Fusarium vrstama (F. graminearum, F. proliferatum, F. subglutinans i F. verticillioides), vrsta F. proliferatum bila je prisutna kod svih ispitivanih hibrida u rangu od 9,3% (ZP 427) do 30,7% (MAS 48.L), dok je vrsta F. subglutinans bila prisutna kod dva hibrida MAS 40.F (16%) i MAS 56.A (9,3%). Uĉestalost F. graminearum je bila od 0% (KWS Konfites) do 9,3% (MAS 34.B), dok je uĉestalost F. verticillioides bila od 0% (MAS 34.B i ZP427) do 21,3% (MAS 48.L). U uzorcima zrna, Aspergillus vrste nisu bile identifikovane. Hibridi kukuruza statistiĉki su znaĉajno uticali na sadrţaj ispitivanih mikotoksina. Hibrid MAS 34.B imao je statistiĉki znaĉajno viši sadrţaj AFB1 i DON u odnosu na druge hibride. Sadrţaj FBs bio je najviši kod hibrida MAS 34.B (1202 mg kg-1 ), a najmanji kod hibrida KWS Konfites (88,33 mg kg-1 ). MeĊutim, sadrţaj FBs nije se razlikovao izmeĊu hibrida MAS 34.B, MAS 40.F i MAS 56.A, MAS 40.F, MAS 48.L i MAS 56.A i KWS Konfites i ZP 427. Kod svih ispitivanih hibrida, sadrţaji AFB1, DON i FBs bili su ispod maksimalno dozvoljenih koliĉina propisanih zakonskom regulativom Evropske Unije i Republike Srbije u nepreraĊenom kukuruzu. Agroekološki uslovi u 2018. godini pogodovali su razvoju Fusarium vrsta na zrnu kukuruza ispitivanih hibrida, i to posebno fumonizin producenata.

AB  - The main nitrogen (N) sources in soybean production originate from soil fixing bacteria Bradyrhizobium spp. and from mineralization of soil organic N. These sources of N are often not sufficient to cover the N needs of the soybean. The present two-year field study aimed to evaluate the effects of soybean genotypes (Valjevka and Galina) and rates of starter fertilizer N (0, 30, 60, and 90 kg ha(-1)) on quantitative and qualitative parameters and on rain use efficiency (RUE) under contrasting weather conditions in the Pannonian region of Serbia. A field study conducted during two different growing seasons: first year with unfavorable weather conditions and second year with favorable weather conditions. As expected, the quantitative parameters, oil content, and RUE were higher in the year with favorable growing season, the second one. According to measured parameters, the genotype Valjevka performed higher yield potential as compared to the genotype Galina. The highest values of quantitative parameters and RUE were recorded at 60 kg N ha(-1), protein content at 90 kg N ha(-1) and oil content 0 kg N ha(-1) (control). This study suggests that proper genotype selection and application of 60 kg N ha(-1) as a starter dose with rhizobial inoculation could contribute to the high yield, while protein could be altered by N amount, independently on genotype.

AB  - Field experiment was conducted to examine the impacts of two sowing dates (8 April - first date of sowing and 21 April - second date of sowing) and four nitrogen rates (0, 60, 120 and 180 kg ha(-1)) on the productivity of maize hybrid 'ZP 434' in the Pannonian region of Serbia during 2016 and 2017 seasons. The dry period during late vegetative development and grain filling stage in 2017 decreased ear traits, grain yield, starch and oil contents, nitrogen agronomic (NAE) and nitrogen use efficiency (NUE). The highest number of grains per ear, starch and oil contents, starch and oil yields and lower rainfall use efficiency (RUE) and protein content were obtained from the early sowing date. The ear traits, grain yield, RUE, protein content, oil content and yield of starch, protein and oil significantly increased while NAE, NUE and starch content significantly decreased with increasing nitrogen rate. The results indicated a significant inverse correlation between starch and protein contents, which prevents the improvement of these two parameters simultaneously. Thus, timely sowing and nitrogen input should be used as long term management strategies for increasing maize yield and grain quality.

AB  - Maize silage is source of palatable and high-energy forage for ruminants. Therefore, production of high quality forage maize represents an essential strategy for stable production of milk and meat on livestock farms. This study examined the effect of harvest date (early dent, at half milk line, at three quarters milk line and black layer) on the quantitative and qualitative parameters of whole maize plant under contrasting climatic conditions in the Srem-Serbia. A 2 × 4 factorial (two years and the four cutting times) randomized blocks design was used, with three replications. The plant height, stem diameter, number of leaves per plant, forage yield, dry matter yield and dry matter content were higher in 2014 probably due to favorable weather conditions. With the delay of the harvest the forage yield, crude protein content, acid detergent fiber (ADF) and neutral detergent fiber (NDF) decreased, and dry matter yield, dry matter content and ear percentage increased. Sufficiently high dry matter content and ear percentage were achieved at the third harvest. However, the delay of harvested time reduces the quality parameters of the biomass, but this loss in the entire plant is moderated by grain filling.

AB  - Due to its divergent chemical composition and good nutritional properties, pollen is not only important as a potential food supplement but also as a good substrate for the development of different microorganisms. Among such microorganisms, toxigenic fungi are extremely dangerous as they can synthesize mycotoxins as a part of their metabolic pathways. Furthermore, favorable conditions that enable the synthesis of mycotoxins (adequate temperature, relative humidity, pH, and a(w) values) are found frequently during pollen collection and/or production process. Internationally, several different mycotoxins have been identified in pollen samples, with a noted predominance of aflatoxins, ochratoxins, fumonisins, zearalenone, deoxynivalenol, and T-2 toxin. Mycotoxins are, generally speaking, extremely harmful for humans and other mammals. Current EU legislation contains guidelines on the permissible content of this group of compounds, but without information pertaining to the content of mycotoxins in pollen. Currently only aflatoxins have been researched and discussed in the literature in regard to proposed limits. Therefore, the aim of this review is to give information about the presence of different mycotoxins in pollen samples collected all around the world, to propose possible aflatoxin contamination pathways, and to emphasize the importance of a regular mycotoxicological analysis of pollen. Furthermore, a suggestion is made regarding the legal regulation of pollen as a food supplement and the proposed tolerable limits for other mycotoxins.

abstract = "Due to its divergent chemical composition and good nutritional properties, pollen is not only important as a potential food supplement but also as a good substrate for the development of different microorganisms. Among such microorganisms, toxigenic fungi are extremely dangerous as they can synthesize mycotoxins as a part of their metabolic pathways. Furthermore, favorable conditions that enable the synthesis of mycotoxins (adequate temperature, relative humidity, pH, and a(w) values) are found frequently during pollen collection and/or production process. Internationally, several different mycotoxins have been identified in pollen samples, with a noted predominance of aflatoxins, ochratoxins, fumonisins, zearalenone, deoxynivalenol, and T-2 toxin. Mycotoxins are, generally speaking, extremely harmful for humans and other mammals. Current EU legislation contains guidelines on the permissible content of this group of compounds, but without information pertaining to the content of mycotoxins in pollen.

AB  - In this study, a total of 30 poultry (chicken and laying hens) feed samples collected from different poultry farms in Serbia in 2016 were tested for fungal and aflatoxin contamination. Using the plate count and standard mycological methods, total fungal counts and potentially toxigenic fungal genera were determined. Natural occurrence of aflatoxin B1 (AFB1) was detected by ELISA (enzyme-linked immune sorbent assay) method. The total fungal count was in the range from 1 x 102 (2 log CFU g-1 ) to 1.83 x 105 CFU g-1 (5.26 logCFU g-1 ). The majority of the chicken feeds (78.57%) had the total fungal count in the ranged from 1 x 102 to 4.8 x 104 CFU g-1 , whereas in 68.75% of the laying hens feeds it was ranged from 5.3 x 104 to 1.83 x 105 CFU g -1 . In 21.43% of the chicken feeds fungal contamination reached the level above the regulation limits. Three potentially toxigenic fungal genera, Aspergillus, Fusarium, and Penicillium, have been identified. In the tested poultry feed samples, more samples contaminated with Aspergillus were determined compared to samples contaminated by Fusarium and Penicillium species. The AFB1 was detected in concentrations from 1.34 to 18.29 g kg-1 , with an average of 4.47 and 4.56 g kg-1 in the chicken and laying hens feed samples, respectively. In 14.29% of the chicken feeds, the level of AFB1 was above the regulation limits. The obtained results confirmed the importance of continuous mycological and mycotoxicological control of poultry feed, as well as need to improve risk assessments of such contaminants along the food chain.
AB  - U ovom radu je 30 uzoraka hrane za živinu sakupljenih tokom 2016. godine iz različitih živinarskih farmi u Srbiji, ispitivano na prisustvo gljiva i aflatoksina u uzorku. Primenom metode razrešenja i standardnih mikoloških metoda utvrđeni su ukupan broj gljiva i identifikovani su potencijalno toksigeni rodovi gljiva. Prirodna pojava aflatoksina B1 (AFB1) utvrđena je primenom biohemijske imunoadsorpcione metode (ELISA). Ukupan broj gljiva bio je od 1 x 102 (2 logCFU g-1 ) do 1,83 x 105 CFU g-1 (5.26 log CFU g-1 ). Najveći broj uzoraka hrane za piliće (78,57%) imao je ukupan broj gljiva u rangu od 1 x 102 do 4,8 x 104 CFU g-1 , dok je 68,75% uzoraka hrane za nosilje imalo ukupan broj gljiva u rangu od 5,3 x 104 do 1,83 x 105 CFU g-1 . U 21,43% hrane za piliće ustanovljen je nedozvoljen ukupan broj gljiva. Identifikovana su tri potencijalno toksigena roda gljiva Aspergillus, Fusarium i Penicillium. Najveći broj ispitivanih uzoraka hrane za živinu bio je kontaminiran Aspergillus vrstama, u odnosu na Fusarium i Penicillium vrste koje su kontaminirale manji broj uzoraka. Rang sadržaja AFB1 bio je od 1,34 do 18,29 µg kg-1 , sa prosečnim sadržajem od 4,47 µg kg-1 u uzorcima hrane za piliće, i 4,56 µg kg-1 u uzorcima hrane za nosilje. U 14,29% uzoraka hrane za piliće ustanovljen je nedozvoljen sadržaj AFB1. Dobijeni rezultati potvrđuju značaj stalne mikološke i mikotoksikološke kontrole hrane za živinu, kao i potrebu za usavršavanjem procene rizika od štetnih (gljivičnih) kontaminenata u lancu ishrane.

AB  - Modern methods for assessing the welfare of dairy cows are, among other things, often based on the evaluation of animal behaviour. In this regard, behaviour is classified as the most reliable, so‑called animal‑based indicator as its expression comes from the animal itself and indicates a measure in which it has adapted to the environment. Starting from the need to explore the state of welfare and the ability to demonstrate adequate behaviour in dairy farms in Serbia, the Welfare Quality® Assessment Protocol for Cattle (2009) was used in this study. The overall assessment of behaviour was carried out by analysing four main criteria: social, other forms of behaviour, human‑animal relationship and emotional state. The results of the study conducted on a total of 16 dairy farms (N = 4,833 cows) show that the conditions for ensuring appropriate behaviour meet only minimum standards and that the greatest welfare risks arise from the impossibility of expressing natural behaviour, such as exploratory behaviour. The most pronounced negative tendencies within the assessment of the emotional status were those expressed to distress, frustration and boredom. Although the estimated general condition does not differ substantially from the same on EU farms, the need for its improvement is imposed first of all in terms of ensuring greater freedom of movement and more stimulating environment in cattle rearing.

AB  - Sensitivity of 24 isolates of Colletotrichum destructivum O'Gara, collected from alfalfa plants in Serbia, to eight selected fungicides, was investigated in this study. Molecular identification and pathogenicity test of isolates tested were also performed. Fungicide sensitivity was evaluated in vitro, using mycelial growth assay method. All isolates exhibited significant pathogenicity, causing necrosis at the alfalfa seedling root tips two days after inoculation. Using the primer pair GSF1-SR1 and by comparing the amplified fragments of the tested isolates with the marker (M), the presence of the amplicon of the expected size of about 900 bp was determined for all isolates. The isolates tested in this study showed different sensitivity towards fungicides in vitro. Mycelial growth was highly inhibited by QoI (quinone outside inhibitors) fungicide pyraclostrobin (mean EC50=0.39 mu g mL(-1)) and by DMI (demethylation-inhibiting) fungicide tebuconazole (mean EC50=0.61 mu g mL(-1)), followed by azoxystrobin (mean EC50=2.83 mu g mL(-1)) and flutriafol (mean EC50=2.11 mu g mL(-1)). Multi-site fungicide chlorothalonil and MBC (methyl benzimidazole carbamate) fungicide thiophanate-methyl evinced moderate inhibition with mean EC50=35.31 and 62.83 mu g mL(-1), respectively. Thirteen isolates were sensitive to SDHI (succinate dehydrogenase inhibitors) fungicide boscalid and fluxapyroxad, (mean EC50=0.49 and 0.19 mu g mL(-1), respectively), while the rest of isolates were highly resistant.

In this paper, the data on area, production and yield of alfalfa observations from 1947 to 2018 and their variation and trends are analysed. The data indicate wide differences in the harvested area, total production and yield of alfalfa. The analysis of data indicates that harvested area and total production of alfalfa have declined over the past decades. Yield trend shows strong yield increase during 1950-1980 followed by periods of declined growth rates to 1990. After 1990s, dry matter yield has been stagnant. However, the increase, decrease and stagnation in yield are not strictly linear.

Međutim, porast, smanjenje i stagnacija u prinosu nisu strogo linearni.",

AB  - Fusarium graminearum as the main causal agent of Fusarium head blight (FHB) and its ability to produce trichothecenes was investigated by molecular techniques. A total of 37 strains isolated from the wheat, harvested in Serbia in 2005, 2008 and 2015, and previously designated by morphological observation as F. graminearum, were used for trichothecene genotypes characterization. The strains were identified using the species-specific primer set FG16R/FG16F while genotypic characterization was done using specific TRI13 and TRI3 sequences of the trichothecene gene clusters. The PCR assays identified all strains as species of F. graminearum sensu stricto with the DON/15-ADON genotype. The quantification of the mycotoxin (DON) was performed using the biochemical assay. The high levels of DON (>20,000 mu g kg(-1)) were recorded in all of the strains from 2005, four strains from 2008 and two strains from 2015. Weather data of the investigated seasons, showed that the optimal temperature, frequent rains and high relative humidity (RH) was very favourable for the development of F. graminearum, affecting the DON biosynthesis.

AB  - This study was carried out in order to investigate the natural occurrence of toxigenic fungi and levels of zearalenone (ZEA), deoxynivalenol (DON) and aflatoxin B1 (AFB1) in the maize stored immediately after harvesting in 2016 and used for animal feed in Serbia. A total of 22 maize samples were collected from four different districts across the country: City of Belgrade (nine samples), Šumadija (eight samples), Podunavlje (four samples) and Kolubara (one sample). Toxigenic fungi were identified according to the morphological characteristics whereas the mycotoxins contamination were detected using biochemistry enzyme-linked immuno-sorbent (ELISA) assay. The tested samples were mostly infected with Aspergillus, Fusarium and Penicillium spp., except that one sample originated from Kolubara was not contaminated with Aspergillus species. Fusarium graminearum was the most common species in the maize sample from Kolubara district (60%), F. verticillioides in the maize samples from Podunavlje (43.75%) and City of Belgrade (22.4%) districts, and Penicillium spp. in the maize samples from Šumadija district (26.38%). In the analysed maize samples the presence of Aspergillus species was low (0-1.78%). Mycotoxicological analysis revealed the presence of zearalenone (ZEA), deoxynivalenol (DON) and aflatoxin B1 (AFB1) in all the investigated samples, except that DON and AFB1 were not recorded in the samples from Podunavlje and Kolubara districts, respectively. The investigated samples were highly contaminated with ZEA, with incidence of 100% for the samples from Šumadija, Podunavlje and Kolubara districts and 88.89% for the samples from City of Belgrade district. In addition, the samples contamination with DON was 100% and 22.2% for the samples from Šumadija, Kolubara and City of Belgrade, districts, respectively. The highest number of AFB1 positive samples was found in Šumadija district (87.5%), while in the City of Belgrade and Podunavlje districts, 55.56% and 50% AFB1 positive samples were established, respectively. Generally, remarkable infection of all the tested samples with toxigenic fungal species from Aspergillus, Fusarium and Penicillium genera were recorded. In addition, high contamination with mycotoxins ZEA, DON and AFB1 were also recorded; nevertheless, only in one sample the level of DON exceeded the allowed legal limit (1750 μg kg-1 ) according to Regulation for unprocessed maize. Therefore, permanent mycological and mycotoxicological analyses of maize grain are necessary for risk assessment of fungal and mycotoxin contamination throughout the food chain.

Ukupno 22 uzoraka zrna kukuruza sakupljeni su iz četiri regiona u Srbiji: Beogradski (devet uzoraka), Šumadijski (osam uzoraka), Podunavski (četiri uzorka) i Kolubarski (jedan uzorak). Toksigene vrste gljiva su identifikovane na osnovu morfoloških osobina, a sadržaj mikotoksina određen je pomoću biohemijske, imunoadsorpcione enzimske metode (ELISA). Ispitivani uzorci kukuruza većinom su bili inficirani sa Aspergillus, Fusarium i Penicillium spp., izuzev što u uzorku iz Kolubarskog regiona nisu bile identifikovane Aspergillus vrste. Fusarium graminearum bila je najučestalija vrsta u uzorku kukuruza iz Kolubarskog regiona (60%), F. verticillioides u uzorcima iz Podunavskog (43,75%) i Beogradskog regiona (22,4%) i Penicillium spp. u uzorcima iz Šumadijskog regiona (26,38%). U ispitivanim uzorcima kukuruza zastupljenost Aspergillus vrsta bila je niska (0-1,78%). Mikotoksikološkim analizama ustanovljeno je prisustvo zearalenona (ZEA), deoksinivalenola (DON) i aflatoksina B1 (AFB1) u svim ispitivanim uzorcima kukuruza, izuzev što DON nije detektovan u uzorcima iz Podunavskog a AFB1 u uzorku iz Kolubarskog regiona. Ispitivani uzorci su visoko kontaminirani sa ZEA, 100% uzoraka iz Šumadijskog, Podunavskog i Kolubarskog regiona i 88,89% uzoraka iz Beogradskog regiona. Isto tako, sa DON bilo je kontaminirano 100% uzoraka iz Šumadijskog i Kolubarskog regiona i 22,2% iz Beogradskog regiona. Najveći broj AFB1 pozitivnih uzoraka ustanovljen je u Šumadijskom regionu (87,5%), dok je u Beogradskom i Podunavskom regionu ustanovljeno 55,56% i 50% AFB1 pozitivnih uzoraka, respektivno. Uopšteno razmatrajući, u ovim analizama ustanovljena je visoka zastupljenost toksigenih vrsta u svim ispitivanim uzorcima kukuruza. Isto tako, ustanovljena je visoka kontaminiranost uzoraka sa mikotoksinima ZEA, DON i AFB1, iako je samo u jednom uzorku sadržaj DON premašio dozvoljeni limit (1750 μg kg-1 ) prema zakonskoj regulativi za neprerađeni kukuruz. Zbog toga, stalne mikološke i mikotoksikološke analize zrna kukuruza neophodne su radi ocene rizika od gljivične i mikotoksin kontaminacije u lancu ishrane.

AB  - Agroecological and climatic conditions in Serbia greatly affected the development of toxigenic fungi and occurrence of mycotoxins in the maize. The presence of fungal toxigenic Aspergillus and Fusarium species and levels of aflatoxin B 1 (AFB 1) and sum of fumonisins B 1 , B 2 and B 3 (FBs) were established in 127 maize kernel samples harvested during 2012 (37 samples) and 2013 (90 samples). The periods of silking and grain filling of the maize in 2012 in comparison to 2013 were characterised with extremely dry spells, with high temperatures and low precipitation sums. The mean incidences of A. flavus and F. verticillioides were 50.4 and 11.7% in 2012 and 18.9 and 33.4% in 2013, respectively. According to the regulations of the World Health Organisation, unacceptable levels of AFB 1 (>20 μg kg-1) and FBs (>2000 μg kg-1) were established in the 30.6 and 24.1% samples of 2012 and 16.7 and 40% maize kernel samples of 2013, respectively. It can be concluded that high temperatures and low precipitation sums in 2012 favoured the development of A. flavus affecting the high level of AFB 1 , in comparison with F. verticillioides and the production of FBs. There was no positive correlation between the incidences of A. flavus and F. verticillioides, while a statistically significant positive correlation has been found between AFB 1 and FBs levels, in both investigated years (2012-2013). This indicates that the mycotoxin production depended more on weather conditions than on the distribution of corresponding toxigenic fungal species.
AB  - Agroekološki i klimatski uslovi u Srbiji veoma su pogodni za razvoj toksigenih gljiva i njihovih mikotoksina u kukuruzu. Prisustvo toksigenih vrsta gljiva iz rodova Aspergillus i Fusarium, kao i nivoi aflatoksina B1 (AFB1) i ukupnih fumonizina B1, B2 i B3 (FBs) utvrđeni su u 127 uzoraka zrna kukuruza iz berbe tokom 2012 (37 uzoraka) i 2013. godine (90 uzoraka). U fenofazama svilanja i nalivanja zrna kukuruza u 2012. u odnosu na 2013. godinu zapaženi su ekstremno sušni periodi sa visokim temperaturama i niskim količinama padavina. Prosečne vrednosti za učestalost vrsta A. flavus i F. verticillioides bile su 50,4 i 11,7% u 2012., odnosno 18,9 i 33,4% u 2013. godini. Prema pravilniku Svetske zdravstvene organizacije (WHO) nedozvoljeni nivoi AFB1 (>20 µg/kg) i FBs (>2000 µg/kg) utvrđeni su u 30,6% i 24,1% uzoraka u 2012., odnosno u 16,7% i 40% uzoraka u 2013. godini. Na osnovu dobijenih rezultata zaključeno je da su visoke temperature i niske količine padavina u 2012. godini uslovile značajno veću učestalost A. flavus i visoku produkciju AFB1 u poredjenju sa vrstom F. verticillioides i produkcijom FBs. U obe ispitivane godine (2012-2013), između učestalosti A. flavus i F. verticillioides nije ustanovljena pozitivna korelacija, dok je statistički značajna pozitivna korelacija ustanovljena između nivoa AFB1 i FBs. Ovo ukazuje da produkcija mikotoksina je više zavisna od vremenskih uslova u odnosu na distribuciju toksigenih vrsta gljiva.

AB  - Rhizosphere microorganisms are essential for plant growth and development. Many factors, including environmental conditions, genotype, seed inoculation with plant growth promoting rhizobacteria (PGPR) and plant growth stages, influence rhizosphere microbiology. In this study, the dynamics of nitrogen and microbiological soil status at different growth stages of two maize hybrids, as well as their grain yield were analyzed, under the influence of seed inoculation with inoculant containing Azotobacter chroococum, Azotobacter vinelandii, Bacillus megaterium, and Bacillus licheniformis on during three experimental years. Higher nitrogen amount (NA), total number of microorganisms (TNM), number of azotobacters (NAZ), number of aminoheterotrophs (NAM), total number of sporogenic bacteria (NS), number of actinomycetes (NAC), number of oligotrophic (NO) and grain yield, as well as lower number of fungi (NF) were obtained under favorable environmental conditions. The hybrid NS 6010 had higher values of NA, TNM, NAZ, NAM, NO, and grain yield than hybrid Dijamant 6. What is more, higher NA, TNM, NAZ, NAM, NO, and grain yield were obtained under inoculation treatment, demonstrating that the microorganisms improve maize production and microbial abundance in the rhizosphere. The highest TNM, NAM, NF and NO were determined at stage 6-7 leaves, while the highest NA and NAC were at silking stage and NAZ at wax ripeness stage. Accordingly, hybrid choice and seed inoculation could serve as a good management practice for an increase in maize grain yield, and improved microbial population and nitrogen amount in the rhizosphere.

AB  - The effects of three intra-row spacings (20, 24 and 28 cm) with inter-row spacing of 70 cm and seed inoculation with plant-growth-promoting bacteria (PGPB) [(Azotobacter chroococum, Azotobacter vineland, Bacillus megaterium and Bacillus licheniformis)] were investigated on stem diameter (SD), stem lodging (SL), percentage of barren plants (PBP), grain yield (GY) and rain-use efficiency (RUE) in maize hybrid Dijamant 6 in the province of Vojvodina, Northern Serbia in 2006, 2007 and 2008. The highest SD and GY and the lowest SL and PBP were recorded in favorable climatic conditions in 2006. The lowest RUE was recorded in 2008 (unfavorable climatic conditions). The lowest SD and RUE and the highest SL, PBP and GY were obtained at the smallest spacing between plants in a row (20 cm). Seed inoculation significantly increased SD, GY and RUE, and SL and PBP significantly decreased. Generally, in Northern Serbia and similar ecological regions, treatment using 20 cm intra-row spacing (plant density of 71429 plants ha(-1)) and seed inoculation could be recommended to improve stem lodging resistance, decrease the number of barren plants and increase grain yield. To reduce yield losses in high crop densities, farmers should adopt appropriate crop management practices such as inoculation of seed with bio-fertilizer.

AB  - Grass-legume mixtures represent complex communities of grasses and legumes that make better use of resources and have a number of positive traits in comparison to monoculture. The aim of our research was to examine competitive ability of perennial ryegrass in mixtures with lucerne and red clover (50/50, 70/30) in condition of fertilization with three different nitrogen levels (0, 50, 100 kg ha-1). Dry matter yield of perennial ryegrass in mixtures with red clover was higher compared to mixtures with lucerne. Nitrogen had a very significant impact on perennial ryegrass production. Added N significantly increase DM production of grass treatment with 100 kgN ha-1. The values, of relative yield above 1 (RY >1), aggressivity index and competitive balance index, above 0 (Ag > Cbg > 0) indicated higher competitive ability of perennial ryegrass in relation to legumes. Competitive ability of ryegrass was higher in 70/30 mixtures and mixtures with lucerne. N fertilization increases competitive ability of ryegrass and decreases competitive ability of legumes.

AB  - Maize is the very important silage source in the world. Timely harvesting ensure high maize forage yield and quality. Therefore, the study focused on the effects of four harvesting times (starting at the 12 August every 7 days) on yield and qualitative parameters of forage green mass of maize hybrid ZP 677. The experiment was set in Vojvodina Province, Serbia, during the 2013 and 2014 growing seasons. Plant height, stem diameter, number of leaves per plant, ear percentage, forage yield, dry matter content and crude protein content were higher, while stem percentage was lower in 2014 with favorable climatic condition. Forage yield, crude protein content, ADF and NDF decreased, while dry matter content significantly increased with delay in harvesting. The maize hybrid should be harvested when the milk line is three-quarter of the way down the grain that is in the third decade of August.

AB  - Assessment of microbiological quality of bee collected pollen is very important, because of its use as a supplement in the human diet. In this study, 26 samples collected from different location in Serbia were tested for the presence of mold through mycologial analysis. The presence of aflatoxin B1, one of the most dangerous and the most widespread mycotoxin was also determined. It was established that 10 of the investigated samples were contaminated with some genera or species of mold, but all of the investigated samples were contaminated with aflatoxin B1. Considering that there is no unique and official procedure for mycological analysis of bee collected pollen, these findings suggest the need for their establishment. Mycological analysis should be followed by mycotoxicological analysis since the absence of mold does not confirm the absence of aflatoxin B1 in bee pollen.

Mycological analysis should be followed by mycotoxicological analysis since the absence of mold does not confirm the absence of aflatoxin B1 in bee pollen.",

AB  - Species of the genus Fusarium are predominant pathogens in cereals worldwide, while F. graminearum is the most distributed among them. This species synthesises a broad spectrum of mycotoxins (fusariotoxins), among which, trichothecene type B (deoxynivalenol-DON) and zearalenone (ZEA) prevail. The isolates from the collection of the Laboratory of Phytopathology of the Maize Research Institute, Zemun Polje were used to study diversity of the F. graminearum species. Twelve selected isolates were collected in the 2005-2016 period from wheat and barley kernels in various locations in Serbia. The aim of this study was to observe variability of the F. graminearum species regarding isolate pathogenicity, mycelium growth, macroconidium size, as well as DON and ZEA production potential by the ELISA method. All the observed isolates indicated pathogenic potential in the field and expressed different viability ranging from 1.75 to 3.75. Besides different viability, microscopic and macroscopic properties of isolates also diverged. The isolates of F. graminearum produced average concentrations of DON amounting 119. 9 and 33.4 ug/g (isolates from wheat and barley, respectively), while the average concentration of ZEA was 40.14 ug/kg (isolates from wheat) and 31.25 ug/kg (isolates from barley). A correlation between production of DON and ZEA was not observed in the isolates of F. graminearum.

Odabrano je 12 izolata koji su prikupljeni u periodu od 2005. do 2016. godine, poreklom sa zrna pšenice i ječma iz različitih lokaliteta na teritoriji Srbije. Cilj rada je bio da se ispita varijabilnost vrste F. graminearum u pogledu patogenosti izolata, porasta micelije, veličine makrokonidija kao i u potencijalu produkcije DON i ZEA pomoću ELISA metode. Svi ispitivani izolati su ispoljili patogenost u polju uz različit stepen agresivnosti koja je varirala od 1,75 do 3,75 (na skali 1-7).

AB  - Perennial ryegrass is a very important and widespread grass species used for livestock nutrition, in particularly ruminants. As a species that is most commonly used on grasslands, it is grown in mixtures with other types of grasses and legumes. The objective of the research was to investigate the performance of perennial ryegrass at various proportions in the mixtures with red clover and lucerne, and how different levels of N fertilization affect its competitiveness. Ryegrass achieved the highest yield with lucerne at seeding rate 50:50 and with red clover at seeding rate 70:30. Relative grass yield (RYg) of mixtures ranged from 1.01 to 1.55 respectively, which means that ryegrass in mixtures achieved 0.1-55% greater yield than pure ryegrass crop. N fertilization increased DMY and RYg, leaf : steam ratio, specific leaf area (SLA), leaf area ratio (LAR) and leaf area index (LAI) in both years thus increasing the competitive capability of perennial ryegrass.

AB  - Rainfall is one of the most important environmental factors influencing crop production under dry land farming conditions. In the Republic of Serbia, the soybean is produced under rainfed conditions, and therefore online monitoring of the rainfall use efficiency (RUE) is essential for efficient management of production. The research aim was to estimate the effects of amount rainfall during the growing season (RGS) and average monthly rainfall on soybean grain yield (GY) in the Vojvodina during the sixteen year period (2000-2015). Distributions of RGS were not satisfactory and negatively influenced the expression genetic yield potential of cultivars. Rainfall deficits during the growing season limited the soybean plant reproductive growth stages leading to GY loss. The coefficient of variation indicated that RGS and monthly rainfall changed moderately from year to year. Regression equations showed that GY tended to increase with the amount of rainfall. GY had strong positive relationship with RGS and rainfall in May, July and August. Since the amount and distribution of rainfall during growing season are critical determinants of GY, soybean cultivars of shorter vegetation periods should be developed and cultivated so that maximum utilization of rainfall is ensured.

AB  - The aim of the study was to investigate the effect of N fertilization on dry matter and nitrogen yield and botanical composition of lucerne and its mixtures with grasses, as well as the effect of different levels of N fertilizer on nitrogen utilization efficiency. The study included pure lucerne and lucerne mixtures with grasses and legumes (cocksfoot, tall fescue and sainfoin) and four fertilization treatments with nitrogen (0, 70, 140 and 210 kg ha 1). In a two-year study, it was concluded that lucerne uses nitrogen in fertilizers more efficiently, compared to its mixtures and that the utilization efficiency increases with the increasing share of legumes in the mixture. The four component mixture of lucerne, cocksfoot, tall fescue and sainfoin, of all studied mixtures, was characterized by the largest increase in yield per unit of added nitrogen and the percentage of nitrogen utilization from mineral fertilizers in the relative value of 54.52%. Although the addition of nitrogen lead to a progressive increase in yields, the value of the realized yield per unit of added N decreased. The highest utilization of N from mineral fertilizers was recorded in the treatment with 70 kg N ha(-1) (51.2%).

In a two-year study, it was concluded that lucerne uses nitrogen in fertilizers more efficiently, compared to its mixtures and that the utilization efficiency increases with the increasing share of legumes in the mixture. The four component mixture of lucerne, cocksfoot, tall fescue and sainfoin, of all studied mixtures, was characterized by the largest increase in yield per unit of added nitrogen and the percentage of nitrogen utilization from mineral fertilizers in the relative value of 54.52%. Although the addition of nitrogen lead to a progressive increase in yields, the value of the realized yield per unit of added N decreased. The highest utilization of N from mineral fertilizers was recorded in the treatment with 70 kg N ha(-1) (51.2%).",

AB  - The effect of sward structure of the mixtures and nitrogen fertilization on grass-legume silage quality was investigated over two years. The study included Lucerne (Medicago sativa) in monoculture and in mixtures with cocksfoot (Dactylis glomerata), tall fescue (Festuca arundinacea) and sainfoin (Onobrychis sativa). Nitrogen fertilizer was applied to the field plots at four different rates: 0, 70, 140 and 210 kg ha(-1). The quality of lucerne silage was inferior to lucerne silage mixed with grasses due to the greater content of ammonia nitrogen (NH3-N), acetic (AA) and butyric acids (BA), and reduced content of the lactic acid (LA). Gradual increase of N fertilization significantly has increased the content of NH3-N, AA and BA and decreased the content of LA.

AB  - The aim of this study was to determine the effects of the inoculation of maize seeds with mixtures of bacteria (Azotobacter chroococum, Azotobacter vinelandi, Bacillus megaterium, Bacillus licheniformis) during different phenophases (6-7 leaves, silking and wax ripeness stage) and on the nitrogen dynamics, total number of microorganisms, number of azotobacter and aminoheterotrophs in Chernozem and grain yield of maize hybrid ZP 684 during 2006, 2007 and 2008. Nitrogen amount in soil was significantly higher in 2006, due to favourable meteorological conditions for microbial activity (higher total number of microorganisms and number of azotobacter), than in 2007 and 2008. The minimum amount of nitrogen was in the stage of wax ripeness although the total number of microorganisms, azotobacter and aminoheterotrophs were the largest. Seed inoculation of maize significantly increases the values of all studied parameters.

AB  - In this study, the influence of nitrogen (N)-fertilization on Fusarium head blight (FHB) intensity (disease index), spike weight (SW), grain weight per spike (GWS), fungal incidence and deoxynivalenol (DON) and zearalenone (ZON) contamination was evaluated in winter wheat after artificial inoculation with Fuserium graminearum under field conditions. The trial was conducted using two Serbian wheat cultivars (Pobeda and Renesansa) during two growing seasons (2010-2011 and 2011-2012). Three nitrogen rates, 0, 75 and 150 kg N ha(-1) were evaluated. Nitrogen at higher rates (75 and 150 kg ha(-1)) significantly increased SW and GWS in 2011 but there was no significant impact on FHB index in both growing seasons. ;Cultivars did not differ significantly in SW and GWS; however, FHB index was significantly higher (P = 0.05) in Renesansa in 2012. The effect of N rates was not significant on incidence of F. graminearum and DON and ZON levels in wheat kernels in 2011, but it was significant (P  lt = 0.01) in 2012 in which the highest level of incidence of E graminearum and mycotoxins was observed in the treatment with 150 kg N ha(-1). In both growing seasons, the effects of cultivar and spike treatments were significant (P  lt = 0.01) for DON, whereas these effects were not significant for ZON in 2011. Higher levels of DON were observed in Pobeda, whereas Renesansa had higher levels of ZON. Furthermore, there were higher levels of DON and ZON in inoculated than non-inoculated spikes in both growing seasons. These results indicated that nitrogen fertilization did not increase FHB intensity in both growing seasons and did not increase levels of DON and ZON in 2011. On the other hand, artificial inoculation significantly increased FHB index in both growing seasons, resulting in greater contamination of kernels with E graminearum and mycotoxins, in particular DON. Although the two cultivars differed in their effects on some of the investigated parameters, both were susceptible to FHB and mycotoxin accumulation, in particular DON.

AB  - In this paper, the incidence of Fusarium-infected grain of winter wheat and the content of mycotoxin deoxynivalenol (DON) was studied in two Serbian cultivars Simonida and NS40S, both harvested in 2014. The level of Fusarium contamination of wheat grain was determined using phytopathological techniques based on the standard methodology while DON was detected by enzyme-linked immuno-sorbent assay (ELISA). The incidence of Fusarium-infected grain ranged from 12 to 19% for Simonida and NS40S, respectively. Fusarium graminearum, as well-known producer of DON mycotoxin, was identified among Fusarium species. In addition, Alternaria spp. was isolated in high percentage, with an average incidence of 53% (Simonida) to 63% (NS40S).The average content of DON ranged from 424 μg kg-1 to 1101 μg kg-1 for Simonida and NS40S cultivars, respectively. Statistically insignificant negative correlation (r = - 0.18) was determined between Fusariuminfected grain and DON in the cultivar Simonida and statistically insignificant positive correlation (r = 0.11) in the cultivar NS40S. The mean levels of DON in studied wheat samples of both tested cultivars were not higher than the maximum permitted limit (1250 μg kg-1) although the level of Fusarium-infected grain of both cultivars was relatively high. These results indicate that both wheat cultivars are susceptible to Fusarium infection and DON mycotoxin production in agro-ecological conditions of Serbia, but the cultivar NS40S being more susceptible compared to cultivar Simonida. In view of all stated above, regular health check of grains and developing strategies for integrated monitoring of incidence of Fusarium head blight are necessary preventive measures in protection of winter wheat.

Zbog svega navedenog, redovna zdravstvena kontrola zrna i razvijanje strategije integralnog monitoringa fuzarioze klasa neophodne su preventivne mere borbe u zaštiti pšenice.
