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 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.

Nivo fuzariozne kontaminacije zrna pšenice određen je primenom fitopatoloških testova standardne metodologije a DON je detektovan primenom imunoadsorpcione enzimske metode (ELISA). Incidenca Fusarium-zaraženih zrna bila je u proseku za sve ispitivane uzorke od 12% (Simonida) do 19% (NS40S). Od Fusarium vrsta identifikovana je jedino Fusarium graminearum, kao dobro poznati producent DON mikotoksina. Pored ove gljivične vrste, u visokom procentu izolovana je Alternaria spp. sa prosečnom incidencom od 53% (Simonida) do 63% (NS40S). U ispitivanim uzorcima pšenice prosečan sadržaj DON bio je od 424 μg kg-1 (Simonida) do 1101 μg kg-1 (NS40S). Između Fusarium-zaraženih zrna i DON utvrđena je statistički neznačajna negativna korelacija (r = - 0.18) kod sorte Simonida i statistički neznačajna pozitivna korelacija (r = 0.11) kod sorte NS40S. Prosečne koncentracije DON u ispitivanim uzorcima pšenice kod obe ispitivane sorte nisu bile iznad maksimalno dozvoljenog limita iako je nivo fuzariozne kontaminacije zrna obe ispitivane sorte bio visok. Ovi rezultati ukazuju da su obe ispitivane sorte pšenice osetljive prema fuzarioznoj infekciji i produkciji DON mikotoksina u agroekološkim uslovima Srbije, s tim što je sorta NS40S osetljivija u odnosu na sortu Simonida. Zbog svega navedenog, redovna zdravstvena kontrola zrna i razvijanje strategije integralnog monitoringa fuzarioze klasa neophodne su preventivne mere borbe u zaštiti pšenice.

AB  - Natural occurrence of Fusarium spp. and concentrations of mycotoxin deoxynivalenol (DON) in the grain of the winter wheat moderately susceptible to Fusarium head blight (FHB) has been studied. Grain samples were collected from wheat crops intended mainly for human consumption. All wheat crops were treated with fungicides before (a.i. flutriafol - formulated as Fluoco, applied in dose of 0.5 l ha-1) and during the flowering phase of growing (a.i. thiophanate-methyl + epoxiconazole formulated as Eskorta plus and a.i. thiophanate-methyl formulated as Funomil, applied in doses of 0.75 and 0.5 l ha-1, respectivily). Among of Fusarium species only F. graminearum, as a well known producer of DON, was identified. This fungus was identified in 15 of 19 samples (78.9%) with incidence in positive samples of 2 to 28% (average, 14.0%). Presence of DON was established in 13 of a total 19 investigated wheat grain samples (68.4%). In positive samples DON was detected in concentrations from 69 to 918 μg kg-1 (average, 478 μg kg-1). DON showed a significant and positive correlation at P≥0.05 with grain moisture content (r = 0.52*). Between the frequency of F. graminearum and concentration of DON and between the frequency of F. graminearum and grain moisture content, positive correlation was determined, but without statistical significance (r = 0.44 and r = 0.29, respectively).

AB  - In this study the presence of moulds and mycotoxins in samples of stored maize grains in the period from October 2011 to September 2012 was investigated. Mycological analyses of whole and broken grains showed the presence of species from the genera Alternaria, Aspergillus, Fusarium, Penicillium, Rhizopus and others. Among the Aspergillus and Fusarium genera as potentially toxigenic fungi, Aspergillus flavus was identified with the highest percentage on broken grains (20.38%) whereas F. verticilioides was the predominant species in the whole maize grains (34.04%). In addition, it was obtained that tested samples of stored maize grains were 100% positive with aflatoxin B1 (AFB1), zearalenone (ZON), deoxynivalenol (DON) and fumonisin B1 (FB1) with an average concentration of 1.39 μg kg-1, 71.79 μg kg-1, 128.17 μg kg-1, and 1610.83 μg kg-1, respectively. A significant positive correlation was found between the moisture content and the presence of Fusarium spp. on the broken grains (r = 0.44) and between the moisture content and the concentration of DON (r = 0.61). However, a significant negative correlation was found between moisture content and FB1 (r = -0.34), and between the concentration of ZON and DON mycotoxins (r = -0.58).

Ispitivani uzorci uskladištenog kukuruza bili su 100% pozitivni sa aflatoksinom B1 (AFB1), zearalenonom (ZON), deoksinivalenolom (DON) i fumonizinom B1 (FB1) sa prosečnim koncentracijama 1,39 μg kg-1, 71,79 μg kg-1, 128,17 μg kg-1 i 1610,83 μg kg-1, respektivno. Statistički značajna pozitivna korelacija ustanovljena je između sadržaja vlage i prisustva Fusarium spp. na slomljenom zrnu kukuruza (r = 0,44), kao i između sadržaja vlage i koncentracije DON (r = 0,61). Statistički značajna negativna korelacija ustanovljena je između sadržaja vlage i FB1 (r = -0,34), kao i između koncentracija ZON i DON mikotoksina (r = -0,58).",

AB  - The aim of this study was to investigate the effects of land use changes on the aggregate size distribution, soil structural stability, and soil erodibility in Luvisols on Central Serbia's rainfed farms at a depth of 0.00-0.30 m. Six sites, selected for the study, contained adjacent land uses of natural grassland and arable land that have undergone conversion from grassland for more than 10 years. The inherent problems of Luvisols include weak structured surface horizons susceptible to structure deterioration, where tilled when wet or when heavy machinery is used. Aggregate size distribution and soil structural stability in the topsoil was tested by soil dry and wet sieving. Soil erodibility was assessed with the USLE-K factor. The natural grassland served as a control against which to assess changes in soil properties resulting from the removal of natural vegetation or cultivation of soil. The results showed that conversion of natural grassland to dry land farming led to a significant degradation of the soil structure. Aggregate separation by dry-sieving indicated that the natural grassland had significantly fewer unfavorable cloddy aggregates (>10 mm) and more agronomically most valuable aggregates (0.25-10 mm) than the arable soils. The mean weight diameter of dry aggregates (MWDdry) was greater in the grassland (7.0 mm) compared to the arable soils (9.7 mm). The arable soil had significantly lower (1.03) structure coefficient (Ks) than grassland soils (2.77). Higher percentages of water stable aggregates (WSA) >0.25 mm were found under natural grassland (50 %) than in arable fields (41 %). In addition, grassland soil had significantly higher mean weight diameter (0.92 mm) of wet stable aggregates (MWDwet) than arable soils (0.81 mm). Tillage of the unaltered grassland significantly increased the soil erodibility measured by the USLE-K factor. The USLE-K factor was approximately by 17% greater in the arable soil than in the grassland, indicating the vulnerability of the arable soil to water erosion. In summary, the results showed that the tillage of the grassland degraded the soil structure, leaving soils more susceptible to the erosion in the temperate climate zone. This suggests that land disturbances should be avoided in the grasslands in the study region of the Central Serbia.
