AB  - The aim of this study was to examine the effects of management practices and biofertilization on microbial activity in rhizosphere and yield of medicinal and aromatic plants. Field experiment was performed using four plant species: peppermint (Mentha x piperita L.), pot marigold (Calendula officinalis L.), sweet basil (Ocimum basilicum L.), and dill (Anethum graveolens L.). Treatments were arranged in a split-plot layout in four replicates using basic plots under conventional and organic management, and subplots with and without biofertilizer (Azotobacter chroococcum). Organic management positively affected the microbial number and activity. Biofertilization increased the total microbial number (13-21%), number of ammonifiers (13-60%), nitrogen-fixing bacteria (7-36%), actinomycetes (36-50%), fungi (60-100%), celluloly tic microorganisms (57-217%), dehydrogenase (28-52%) and beta-glucosidase activity (15-39%). The effects of management practices and biofertilization were highly significant for the yield of examined plants. The yields were higher on inoculated treatments both in conventional (5-26%) and organic (7-15%) growing system.

AB  - Plant growth promoting rhizobacteria (PGPR) enhance the plant growth directly by assisting in nutrient acquisition and modulating plant hormone levels, or indirectly by decreasing the inhibitory effects of various pathogens. The aim of this study was to select effective PGPR from a series of indigenous bacterial isolates by plant growth promotion and antifungal activity assays. This study confirmed that most of the isolates from maize rhizosphere were positive for PGPR properties by in vitro tests. Azotobacter and Bacillus isolates were better phosphate solubilizers and producers of lytic enzymes, hydrocyanic acid (HCN), and siderophores than Pseudomonas. Production of indole-3-acetic acid (IAA) and antifungal activity were the highest in Azotobacter, followed by Bacillus and Pseudomonas. The most effective Azotobacter isolates (Azt(3), Azt(6), Azt(12)) and Bacillus isolates (Bac(10,) Bac(16)) could be used as PGPR agents for improving maize productivity. Further selection of isolates will be necessary to determine their efficiency in different soils.

AB  - The aim of this study was to compare abundance of microorganisms in the rhizosphere of four
different medicinal and aromatic plant species (basil, mint, dill and marigold) grown under
both conventional and organic management. The trials were set up on chernozem soil at
experimental field of Bački Petrovac, Institute of Field and Vegetable Crops, Novi Sad
(northern Serbia). Rhizosphere soil samples were collected in two sampling terms during
2015 (June 2 and July 28, 2015) and analysed by the indirect dilution method followed by
plating of soil suspension on selective nutritive media. The obtained results showed
significant differences in microbial abundance between plant species, growing systems and
sampling terms. The highest number of azotobacters and cellulolytic microorganisms were
obtained in rhizosphere of marigold, while total microbial number and fungi were the most
abundant in rhizosphere of basil. The most common population of ammonifiers, free N-fixing
microorganisms and actinomycetes were recorded in rhizosphere of dill. Significantly higher
number of microorganisms was found in organic growing system compared to conventional,
while the number of most tested microbial groups was higher at the first sampling period.

AB  - The effect on sugar beet yield parameters and microbiological soil sta­tus was studied using two techniques of sugar beet inoculation with strains of Azotobacter chroococcum. Cultivar 'Drena' was used in the study, and field trial was set under the conditions of organic farming system in Bački Petrovac. A mixture of three strains of Azotobacter chroococcum was used as microbial fertilizer. Inoculation was performed by: (A) incorporation of strains into soil before sowing; and (B) repeated incorporation of strains into soil two weeks after sowing. PGP characterization of the strains confirmed the ability of producing indole-3-acetic acid (IAA) from 12.63 μg ml-1 to 14.95 μg ml-1, nitrogen fixation, and P-solubilization. Positive effects on the number of azotobacter and free nitrogen fixers in rhizosphere were obtained by inoculation, as well as positive effects on the tested sugar beet yield parameters. The largest increase in root yield, yield of crystal sugar, and yield of polarised sugar compared with the control was obtained by repeated soil inoculation, ranging from 22 to 23%.

AB  - The biofertilizers are found positive contribution to soil fertility, resulting in an increase in crop yield
without causing any environmental, water or soil pollution hazards. Nitrogen fixing and phosphorus
solubilizing bacteria play an important role in nitrogen mobilization and phosphorus solubilization for
the benefit of plant growth. A field experiment to study yield response of maize to inoculation with
rhizobacteria, was conducted during 2013 at experimental field of Institute of Field and Vegetable
Crops in Novi Sad. The maize hybrids (NS 3014, NS 4015, NS 5043, NS 6010 and NS 6030) were
used in the study. The field experiment was laid out in randomized complete block design with four
treatments (control and 3 inoculations) and four replications. Inoculation was done with Pseudomonas
PS2, Bacillus Q7 and their mixture with Azotobacter chroococcum (Q7 + PS2 + AC). Application
method was incorporation immidiately before planting with liquid culture of strains (1 l + 300 l H2O
ha-1). The results showed significant increase in maize yield with inoculation treatments. The best
effect on maize yield was achieved with mixture of strains (19.7%). Significantly higher yield was
obtained for hybrids NS6010 and NS 6030. The highest increase in yield of maize was achieved with
hybrid NS 6030 (32.2%). Statistically significant differences in comparison to the control were

AB  - Plant growth promoting rhizobacteria (PGPR) represent a wide variety of bacteria inhabiting the root surface and root vicinity. They are directly or indirectly involved in promoting plant growth and development via production and secretion of various regulatory compounds in the rhizosphere. PGPR are generally beneficial to a wide range of crops including maize. The main objective of this study was to determine the effect of PGPR strains on the microbial abundance in maize rhizosphere. The trial was conducted at Rimski Šančevi experimental field of Institute of Field and Vegetable Crops in Novi Sad, Serbia. The trial included five maize hybrids (NS 3014, NS 4015, NS 5043, NS 6010 and NS 6030) developed at the Institute and three treatments with microorganisms. Non-inoculated treatment was control. Inoculation was performed with Bacillus Q7, Pseudomonas PS2 and their mixture with Azotobacter chroococcum (Q7 + PS2 + AC). Application method was incorporation immediately before planting with liquid culture of strains (density 109 CFU/ml). It was observed that the certain treatment with rhizobacteria increased the number of all three studied microbial groups in the rhizosphere of the same hybrid. The best effect on the number of microorganisms in the rhizosphere of NS 6010 was achieved with Q7 + PS2 + AC, in NS 5043 with Q7 and with PS2 in NS 4015. The results obtained in this study indicate the importance of PGPR in crop production, which requires a constant expansion of knowledge about the mutual interactions of plants and microorganisms.

abstract = "Plant growth promoting rhizobacteria (PGPR) represent a wide variety of bacteria inhabiting the root surface and root vicinity. They are directly or indirectly involved in promoting plant growth and development via production and secretion of various regulatory compounds in the rhizosphere. PGPR are generally beneficial to a wide range of crops including maize. The main objective of this study was to determine the effect of PGPR strains on the microbial abundance in maize rhizosphere. The trial was conducted at Rimski Šančevi experimental field of Institute of Field and Vegetable Crops in Novi Sad, Serbia. The trial included five maize hybrids (NS 3014, NS 4015, NS 5043, NS 6010 and NS 6030) developed at the Institute and three treatments with microorganisms. Non-inoculated treatment was control. Inoculation was performed with Bacillus Q7, Pseudomonas PS2 and their mixture with Azotobacter chroococcum (Q7 + PS2 + AC). Application method was incorporation immediately before planting with liquid culture of strains (density 109 CFU/ml). It was observed that the certain treatment with rhizobacteria increased the number of all three studied microbial groups in the rhizosphere of the same hybrid. The best effect on the number of microorganisms in the rhizosphere of NS 6010 was achieved with Q7 + PS2 + AC, in NS 5043 with Q7 and with PS2 in NS 4015. The results obtained in this study indicate the importance of PGPR in crop production, which requires a constant expansion of knowledge about the mutual interactions of plants and microorganisms., Rizobakterije koje poboljšavaju rast biljaka (PGPR) predstavljaju širok spektar bakterija koje naseljavaju prostor oko/na površini korena.

AB  - The aim of this study was to compare abundance of microorganisms in the rhizosphere of
maize and soybean grown under conventional and organic management. The trial was set up
on the chernozem soil at the experimental field of Bački Petrovac, Institute of Field and
Vegetable Crops, Novi Sad. Rhizosphere samples were collected in two sampling terms
during 2014 (July 7 and August 14) and analysed by the indirect dilution method followed by
plating of soil suspension on selective nutritive mediums: soil agar for the total number of
microorganisms, meat peptone agar for the number of ammonifiers, Waksman-Carey medium
for the number of cellulolytic microorganisms, synthetic medium for the number of
actinomycetes, Czapek Dox agar for the number of fungi, and N-free medium for the number
of azotobacters and free N-fixers. The results showed significant differences in microbial
abundance between plant species, growing systems and sampling terms. Significantly higher
number of microorganisms was found in rhizosphere of soybean compared to maize, as well
as in organic growing system compared to conventional. Significant differences between
sampling terms were recorded for the number of ammonifiers, azotobacters, fungi and
actinomycetes, while the number of most tested microbial groups was higher in the second
sampling term.

AB  - Among 50 bacterial isolates obtained from maize rhizosphere, 13 isolates belonged to the genus Azotobacter. Isolates were biochemically characterized and estimated for pH and halo tolerance ability and antibiotic resistance. According to characterization, the six representative isolates were selected and further screened in vitro for plant growth promoting properties: production of indole-3-acetic acid (IAA), siderophores, hydrogen cyanide (HCN), exopolysaccharides, phosphate solubilization and antifungal activity (vs. Helminthosporium sp., Macrophomina sp., Fusarium sp.). Beside HCN production, PGP properties were detected for all isolates except Azt 7 . All isolates produced IAA in the medium without L-tryptophan and the amount of produced IAA increased with concentration of precursor in medium. The highest amount of IAA was produced by isolates Azt 4 (37.69 and 45.86 µg ml -1 ) and Azt 5 (29.44 and 50.38 µg ml -1 ) in the medium with addition of L-tryptophan (2.5 and 5 mM). The isolates showed the highest antifungal activity against Helminthosporium sp. and the smallest antagonistic effect on Macrophomina sp. Radial Growth Inhibition (RGI) obtained by the confrontation of isolates with tested phytopathogenic fungi, ranged from 10 to 48%.

AB  - In this study we assessed the number of microorganisms in rhizosphere of peppermint (Mentha × piperita L.) as one of the
important aromatic species in Serbia. The trial was set up on chernozem soil at experimental field of Bački Petrovac, Institute
of Field and Vegetable Crops, Novi Sad (northern Serbia) in 2012, 2013 and 2014. Rhizosphere soil samples were collected
from both conventional and organic grown peppermint. In each year of investigation two samplings (June and July) were
performed for microbiological analysis. Soil samples were analyzed by the standard methods in four replications and
average number of microorganisms was calculated at 1.0 g absolutely dry soil. The results were analyzed in accordance with
three-way model of analysis of variance. The obtained results showed that a significantly higher number of ammonifiers,
azotobacters and free nitrogen-fixing bacteria was recorded in 2012 compared to 2013 and 2014. Also, a significantly higher
number of azotobacters and free nitrogen-fixing bacteria was obtained in organic than in conventional growing. In addition,
significant differences in number of fungi and actinomycetes were recorded between the sampling terms, i.e. significantly
higher numbers of these groups of microorganisms were found in the second term.

AB  - This study was aimed at comparing the abundance of microorganisms in the rhizosphere of four different medicinal and aromatic plant species (basil, mint, dill and marigold) grown under both conventional and organic management on the chernozem soil at the experimental field of Bački Petrovac (Institute of Field and Vegetable Crops, Novi Sad, Serbia). Two sampling terms (June 1 and July 18, 2012) were performed to collect samples for microbiological analyses. The microbial abundance was higher in organic than in conventional system while at the same time significant differences were obtained only with dill rhizosphere. The differences in number of microorganisms belonging to different groups relied upon both plant species and sampling term. Thus, in mint, the recorded number of azotobacters and fungi was significantly higher whereas the number of ammonifiers was significantly lower. The present results indicate that organic growing system affected the abundance of microorganisms in rhizosphere of species investigated, especially in the second term of sampling.
AB  - Cilj istraživanja bio je da se uporedno ispita brojnost mikroorganizama u rizosferi četiri lekovite i aromatične biljne vrste (bosiljak, pitoma nana, mirođija i neven) koje su gajene na konvencionalan i organski način na zemljištu černozem na eksperimentalnom polju u Bačkom Petrovcu (Institut za ratarstvo i povrtarstvo, Novi Sad, Srbija). Uzorci za mikrobiološku analizu uzeti su u dva termina (1. jun i 18. jul 2012. godine). Brojnost mikroorganizama bila je veća u organskom sistemu u odnosu na konvencionalni, ali je značajna razlika zabeležena samo za rizosferu mirođije. Razlike u broju mikroorganizama koji pripadaju različitim grupama zavisile su kako od biljne vrste tako i od termina uzorkovanja. Tako je na primer kod pitome nane zabeležen visoko značajno veći broj azotobaktera i gljiva, dok je broj amonifikatora bio značajno manji. Dobijeni rezultati ukazuju da organski način gajenja više utiče na brojnost mikroorganizama u rizosferi ispitivanih vrsta, posebno u drugom terminu uzorkovanja.

Razlike u broju mikroorganizama koji pripadaju različitim grupama zavisile su kako od biljne vrste tako i od termina uzorkovanja. Tako je na primer kod pitome nane zabeležen visoko značajno veći broj azotobaktera i gljiva, dok je broj amonifikatora bio značajno manji. Dobijeni rezultati ukazuju da organski način gajenja više utiče na brojnost mikroorganizama u rizosferi ispitivanih vrsta, posebno u drugom terminu uzorkovanja.",

AB  - For higher productivity heavy doses of fertilizers and other agrochemicals are applied. This has
led to the emergence of a movement forward specified farming concept based on the traditional
farming philosophy known as organic systems. These systems do not use synthetic chemicals and
in the long run way be more sustainable than inorganic and conventional farming. The purpose
of this study was to investigate microbial abundance in rhizosphere and yield of bean and
soybean in conventional and organic system growing. The trial was set up on chernozem soil at
the Bački Petrovac experiment field of the Institute of Field and Vegetable Crops. Soil samples
of rhizosphere were collected under conventional management and organic management.
Samples for microbiological analyses were taken at two dates (1st June and 18th July). Soil
microbial abundance was significantly greater in organic farming growing compared with
conventional. The total number of microorganisms, number of ammonifiers, azotobacter,
actinomycetes and fungi was higher in rhizosphere in organic production of bean than in
rhizosphere of bean in conventional production. Similar results were obtained in rhizosphere of
soybean in organic production compared to the conventional. Beside the higher of examined
groups of microorganisms in rhizosphere of soybean, the higher number of celulolytic
actinomycetes was obtained, too. The number of nodules on root of soybean in organic
production was three times higher than in conventional. Grain yield was higher in conventional
production than in organic, while in organic production greater yield quality, protein and oil
content, was obtained.

AB  - The aim of the study was to investigate ability of Pseudomonas sp. Q4b, Bacillus sp. Q5a and Azotobacter chroococcum strain 8 to enrich a population of plant growth promoting rhizobacteria (PGPR) in rhizosphere and thus enhance maize growth (Zea mays L.). Experiments were carried out under greenhouse and field conditions, on a chernozem soil. In vitro screening for PGP properties showed significant difference between indole-3-acetic acid (IAA) and siderophores production and phosphosolubilization between Pseudomonas sp. Q4b and Bacillus sp. Q5a. Pseudomonas was estimated as a better producer of hydrogen cyanide (HCN) and siderophores than Bacillus. Bacterial treatments had a significant effect on the number of investigated microbial groups in rhizosphere, and maize growth and yield. Co-inoculation had an advantage compared to single inoculation, while in case of single strains, better effects were achieved in Pseudomonas and Azotobacter treatments. Inoculation increased the number of azotobacters (103.25%), pseudomonads (82.29%) and aerobic spore-forming bacteria (52.65%) as well as height (17.15%) and dry weight (35.48%) of maize plants. The highest plant height was recorded in treatment with Pseudomonas and Bacillus. The highest dry weight and yield were recorded in the treatment with mixture of these three strains.

AB  - Effects of Azotobacter chroococcum inoculation on sugar beet production characteristics and microbiological status in the soil were studied on three different methods of sugar beet inoculation with Azotobacter chroococcum strains. The variety Drena was used in the study. Experiments were carried out at Rimski Sancevi in 2008, 2009 and 2010. Five strains of Azotobacter chroococcum were used as microbial inoculants. Three inoculation methods were applied: (A) strain incorporation into the soil before planting, (B) strain application on soil surface before the first inter-row cultivation and (C) seed inoculation before planting. All five Azotobacter chroococcum strains, in each of the three application methods, showed a positive effect on the production characteristics of sugar beet. The highest yield increases in root (6.45 t ha(-1)) and sugar (0.63 t ha(-1)) was obtained on seed inoculated with strain 10.

AB  - Free-living soil bacteria beneficial to plant growth are usually referred to as plant growth promoting rhizobacteria (PGPR), capable of promoting plant growth by colonizing the plant root.

AB  - The aim of this study was to determine the effects of three different inoculation methods with selected Azotobacter chroococcum strains on productive and technological traits of sugar beet, as well as on the total number of microorganisms and azotobacter in rhizosphere. The results of this two-year study showed that effectiveness of the tested inoculation methods in increasing root yield and sugar content varies greatly, depending on year and azotobacter strains. Effectiveness of inoculation methods was not largely impacted by year on granulated sugar. Achieved granulated sugar yield was significantly higher by using pre-sowing azotobacter application, than by using seed inoculation. A significantly increased number of microorganisms in sugar beet rhizosphere was determined, not only by using pre-sowing azotobacter application but also by using sugar beet seed inoculation. Pre-sowing azotobacter application and inter-row cultivation both caused an equal increase in the number of these bacteria in sugar beet rhizosphere (42.2% and 46.9%). Use of sugar beet seed inoculation caused an increase of 33.7% in the number of azotobacter. In order to achieve higher effectiveness in applying azotobacter on productive and technological traits of sugar beet, and considering determined interaction between a certain year, an inoculation method and a strain, it is necessary for future research to focus on determining efficiency of these strains when they are in a mixture.

AB  - The nonsymbiotic N fixing azotobacter
is an obligate aerobe living in the soil, the
rhizosphere and the plant root. The ability of
various strains to fix atmospheric N positively
affect plant growth and yields. Microbial
interactions with roots may involve either
endophytic or free living microorganisms and can
be symbiotic, assosiative or casual in nature.
Associative and free living microorganisms may
also contribute to the nutrition of plants through a
variety of mechanisms including direct effects on
nutrient awailability (N2-fixation), enhancement of
root growth (PGPR – plant growth promoting
rhizobacteria) as antagonists of root pathogenes
or as saprophytes that decompose soil detritus and
subsequently increase nutrient availability
through mineralization and microbial turnover.
Therefore, the abundance of azotobacter, fungi,
actinomycetes and the total number of
microorganisms in inoculated and non-inoculated
sugar beet rhizosphere were determine in this
study. Simultaneously we studied the effects of
application of nitrogen fertilizer, manure and
harvest residues. Samples of rhizosphere soil were
taken three times in the course of growing season
(May, July, September). The experiment included
two variants (inoculated with Azotobacter
chroococcum and non-inoculated) at four
fertilization levels (non-fertilized control, 50, 100,
150 and 200 kg N/ha), in five replication. Total
number of microorganisms was determined in soil
agar (dilution of 106
). Fungi were determined on
Chapek agar (dilution of 104
), actinomycetes on a
synthetic agar (dilution of 104
) and azotobacters
on Fiodor substrate (dilution of 102
). The results
of the study for all four fertilization types and all
four levels of added N showed that azotobacter
abundance was higher in inoculated treatments
than in the non-inoculated ones. The highest
increases of total microbial abundance and
number of free N-fixing bacteria were recorded in
the inoculated treatments with NPK fertilizer
alone and in the inoculated treatments with 100 kg
N/ha. The highest percentage increases of
azotobacter were obtained in the inoculated
treatments with manure and manure plus harvest
residues, respectively and in the variant without
N.

AB  - Plant growth promoting rhizobacteria (PGPR) are a group of diverse soil bacteria which stimulate the growth of the host plant. It has been shown that Azotobacter chroococcum may be used as biofertilizer for increasing the yield and improving technological characteristics of sugar beet. The effect of three different ways of inoculation of sugarbeet with Azotobacter chroococcum on the production features of sugar beet and microbiological status of rhizosphere soil has been tested. One variety of sugar beet, Drena, was included in the tests in the region Rimski Šančevi, Novi Sad, during 2008 and 2009. Five strains of Azotobacter chroococcum (1, 5, 8, 10 and 14) were used as microbiological fertilizers. There were three variations of inoculation: (A) incorporation in the soil, (B) before the fi rst cultivation, and (C) applying the liquid culture of strain on the seed before sowing. The highest increase in yield of sugar beet roots 6.25 t ha-1 and yield of white sugar 0.91 t ha-1 was achieved with strain 10 with variant of inoculation of soil before the first cultivation. In both years, a positive effect of Azotobacter chroococcum was observed on the total number of microorganisms in the rhizosphere.

AB  - The objective of this study was to investigate the microbial abundance in maize rhizosphere depending on the applied bacterial inoculants and the leaf stage of maize as well as to examine the effect of plant growth promoting rhizobacteria (PGPR) on the early growth of maize plants. In this experiment three bacterial species: Azotobacter chroococcum, Bacillus subtilis and Pseudomonas fluorescens applied individually and in mixture were used as inoculants. One hybrid of maize included in the tests: NS 6010 developed at the Institute of Field and Vegetable Crops in Novi Sad. Experiments were established in laboratory and in greenhouse. The number of the investigated microbial groups depended on the applied bacterial inoculants and the leaf stage of maize plants. Bacterial strains used in this study had a statistically significant influence on the number of microorganisms in maize rhizosphere and a positive effect on the early growth of maize. Bacterial inoculants increased plant height and weight of young maize plants.

AB  - Agricultural soils of Serbia are low in soybean symbiotic bacteria and application of bacteriological preparations has been introduced as a regular cultivation practice when growing soybean. A trial was set up on experimental field of Institute of Field and Vegetable Crops from Novi Sad on chernozem soil using a randomized block design with four replicates. Mineral nitrogen fertilizers were used in rates of 0, 30, 60, and 90 kg ha-1 in the experiment. Each of the nitrogen treatments had two variations, with and without inoculation. The effects of inoculation and different nitrogen fertilizer rates on yield and yield components were determined based on the pod number, seed number, 1000 seed mass and protein and oil content in seeds. Significantly higher pod number was observed in inoculated plants with the application of 30 kg N ha-1. Inoculation with NS-Nitragin increased seed number per plant. In treatment with no mineral nitrogen applied and with application of 30 kg N ha-1 and 60 kg N ha-1, 1000 seed mass was statistically higher in inoculated plants than in uninoculated ones. Inoculation produced statistically significant difference in soybean yield only in the treatment with no mineral nitrogen applied. Inoculation and applied mineral nitrogen rates had no significant effect on protein content in soybean grain.

AB  - Field trials were carried out in 2007 and 2008 on a number of commercial plots in Vojvodina in order to determine how the biofertilizer NS-Betafixin affects root yields, white sugar yields, and microbial abundance in the sugar beet rhizosphere. The use of NS-Betafixin resulted in a significant increase of yield compared with the control (untreated soil). The total number of microorganisms and azotobacter abundance increased as well, while the number of fungi and actinomycetes decreased. Overall, the application of NS-Betafixin can be regarded as a good tool for improving sugar beet yields both quantitatively and qualitatively. It may also reduce fertilizer application and production costs and is environmentally friendly.

Primena NS-Betafiksina dovela je do značajnog poboljšanja prinosa u poređenju sa kontrolom, tj. netretiranim zemljištima, a takođe je došlo do povećanja brojnosti mikroorganizama (ukupan broj i broj azotobaktera) i do smanjenja brojnosti gljiva i aktinomiceta na tretiranom zemljištu. Uopšteno, moglo bi se zaključiti da je biođubrenje, tj. primena NS-Betafixina dobar alat u poboljšanju prinosa šećerne repe kako kvantitativno tako i kvalitativno, može da redukuje primenu đubriva, tj. cenu proizvodnje, a uz to doprinosi poboljšanju životne sredine.

AB  - From the point of view of agricultural production, nitrogen deficiency in the soil results in significant yield losses and yield quality reduction. Symbiotic fixation of atmospheric nitrogen plays a significant role in the supply of plants with nitrogen. Soybean (Glycine max. (L.) Merr.) is one of the most important legumes in Serbia and the world, most notably because of the outstanding chemical composition of its grain. The objective of this paper was to use nitrogen fixation parameters to determine the optimum amounts of mineral nitrogen needed when growing soybean using inoculation with the biofertilizer NS-Nitragin. A trial on a chernozem soil was set up at the Bački Petrovac experiment field of the Institute of Field and Vegetable Crops using a randomized block design with four replicates. The soybean cultivar Balkan and four rates of nitrogen fertilizer (0, 30, 60, and 90 kg N/ha) were used in the experiment. Each of the nitrogen treatments had two variations, with and without inoculation. Just before sowing, the seed was inoculated the soybean biofertilizer NS-Nitragin. The effects of inoculation and different nitrogen fertilizer rates on the effectiveness of symbiotic association were determined at soybean flowering based on the number of nodules formed on the root and the dry matter weight and nitrogen content of the above-ground plant parts, root, and nodules. On an average for all the fertilization treatments, the above-ground weight of the inoculated plants increased by 19% relative to the uninoculated treatments, while the nitrogen content increased by 23%. The nitrogen content of the root system in the inoculated treatments increased by 15% relative to uninoculated plants, and the root system was also more developed (11%) in the former than in the latter. The incorporation of 60 kg N/ha before sowing along with inoculation produced the greatest above-ground and root weights as well as the highest nitrogen content of the above-ground parts and root. Inoculation had a positive effect nodule number (205% increase), weight (59% increase), and nitrogen content (60% increase). Inoculation accompanied by a nitrogen rate of 30 kg/ha produced the best nodulation and the largest weight and highest nitrogen content of nodules.
AB  - Sa stanovišta poljoprivredne proizvodnje, nedostatak azota u zemljištu značajno utiče na smanjenje prinosa i njegov kvalitet. U obezbeđivanju biljaka azotom značajnu ulogu ima simbiotska fiksacija atmosferskog azota. Soja (Glycine max. (L.) Merr.) je jedna od najznačajnijh leguminoza i u svetu i kod nas, pre svega zbog izuzetnog hemijskog sastava zrna. Cilj rada je bio da se preko parametara azotofiksacije utvrdi optimalna količina mineralnog azota u gajenju soje uz inokulaciju mikrobiološkim preparatom NS-Nitragin. Ogled je postavljen na oglednom polju Instituta za ratarstvo i povrtarstvo u Bačkom Petrovcu, na zemljištu tipa černozem, po slučajnom blok sistemu u četiri ponavljanja. U eksperimentu je korišćena sorta soje Balkan, i primenjena su četiri različita nivo đubrenja azotom (kontrola, 30, 60, 90 kg N/ha). Ogled je postavljen u dve varijante, sa inokulacijom (NS-Nitragin za soju) i bez inokulacije. Uticaj inokulacije i različitih koncentracija primenjenih azotnih đubriva na efektivnost simbiotske zajednice određena je u fazi cvetanja soje preko broja formiranih kvržica na korenu, mase suve materije i sadržaja azota u nadzemnom delu biljke, korenu i kvržicama. U proseku za sve varijante đubernja masa nadzemnog dela inokulisanih biljaka povećana je za 19% u odnosu na neinokulisane, dok je sadržaj azota povećan za 23%. Rezultati istarživanja pokazali su da je u korenovom sistemu inokulisanih biljaka sadržaj azota bio veći (15%), a sam korenov sistem razvijeniji (11%) od biljaka koje nisu inokulisane. Predsetvenim unošenjem 60 kg N/ha i inokulacijom ostvarena je najveća masa nadzemnog dela biljke i korena, kao i najveći sadržaj azota u nadzemnom delu i korenu. Inokulacija je na svim ispitivanim varijantama đubrenja pozitivno uticala na broj (205%), masu (59%), ali i na sadržaj azota u kvržicama (60%). Inokulacijom soje i dodatkom mineralnog azota u količini 30 kg/ha ostvarena je najbolja nodulacija, najveća masa i sadržaj azota u kvržicama.

Inoculation accompanied by a nitrogen rate of 30 kg/ha produced the best nodulation and the largest weight and highest nitrogen content of nodules., Sa stanovišta poljoprivredne proizvodnje, nedostatak azota u zemljištu značajno utiče na smanjenje prinosa i njegov kvalitet. U obezbeđivanju biljaka azotom značajnu ulogu ima simbiotska fiksacija atmosferskog azota. Soja (Glycine max. (L.) Merr.) je jedna od najznačajnijh leguminoza i u svetu i kod nas, pre svega zbog izuzetnog hemijskog sastava zrna. Cilj rada je bio da se preko parametara azotofiksacije utvrdi optimalna količina mineralnog azota u gajenju soje uz inokulaciju mikrobiološkim preparatom NS-Nitragin. Ogled je postavljen na oglednom polju Instituta za ratarstvo i povrtarstvo u Bačkom Petrovcu, na zemljištu tipa černozem, po slučajnom blok sistemu u četiri ponavljanja. U eksperimentu je korišćena sorta soje Balkan, i primenjena su četiri različita nivo đubrenja azotom (kontrola, 30, 60, 90 kg N/ha). Ogled je postavljen u dve varijante, sa inokulacijom (NS-Nitragin za soju) i bez inokulacije. Uticaj inokulacije i različitih koncentracija primenjenih azotnih đubriva na efektivnost simbiotske zajednice određena je u fazi cvetanja soje preko broja formiranih kvržica na korenu, mase suve materije i sadržaja azota u nadzemnom delu biljke, korenu i kvržicama. U proseku za sve varijante đubernja masa nadzemnog dela inokulisanih biljaka povećana je za 19% u odnosu na neinokulisane, dok je sadržaj azota povećan za 23%. Rezultati istarživanja pokazali su da je u korenovom sistemu inokulisanih biljaka sadržaj azota bio veći (15%), a sam korenov sistem razvijeniji (11%) od biljaka koje nisu inokulisane. Predsetvenim unošenjem 60 kg N/ha i inokulacijom ostvarena je najveća masa nadzemnog dela biljke i korena, kao i najveći sadržaj azota u nadzemnom delu i korenu. Inokulacija je na svim ispitivanim varijantama đubrenja pozitivno uticala na broj (205%), masu (59%), ali i na sadržaj azota u kvržicama (60%). Inokulacijom soje i dodatkom mineralnog azota u količini 30 kg/ha ostvarena je najbolja nodulacija, najveća masa i sadržaj azota u kvržicama.",

AB  - Rhizosphere appears as the most important niche for microbial activity. It is of direct relevance to nutrient cycling affecting plant nutrition. Rhizosphere can be defined as the root surface and the soil adhering to the root. The aim of this research was to determine the effect of inoculation with Azotobacter chroococcum on the number of microorganisms in the rhizosphere of sugar beet in dependence of fertilization. Field trials were conducted on a chernozem soil at the Rimski Šančevi Experiment Field of the Institute in 2002, 2003 and 2004. The sugar beet hybrid variety Sara was used. Inoculation of sugar beet was performed with a liquid culture of Azotobacter chroococcum strains, which was incorporated into the soil just before planting in the concentration of 109/ml. Differences were registered in population size depending on both the nitrogen dose and fertilisation method. On average, a higher percentage of increase was in the total number of microorganisms (35-118%) than in azotobacter population size (49-52.8%).
AB  - Cilj ovih istraživanja bio je utvrđivanje uticaja inokulacije sa azotobakterom na brojnost mikroorganizama u rizosferi u zavisnosti od doze azota i vrste đubrenja kod šećerne repe. Poljski ogledi su izvedeni u toku 2002, 2003. i 2004. godine na Rimskim Šančevima sa hibridnom sortom Sara stvorenom u Institutu za ratarstvo i povrtarstvo. U radu je određivan ukupan broj mikroorganizama na zemljišnom agaru (razređenja 106), broj gljiva na Čapekovom agaru (razređenja 104), aktinomiceta na sintetičkom agaru (razređenja 104) i azotobaktera na podlozi Fjodora (razređenja 102). Inokulacijom je povećan ukupan broj mikroorgainazama (35-118%), broj azotobaktera (49-52,8%), i gljiva (7,5-19,7%). Broj aktinomiceta je smanjen inokulacijom (1,6-5,4%). Najveći broj azotobaktera dobijen je na varijanti bez dodatka azota, a najmanji sa 200 kg N/ha. Najveći broj gljiva dobijen je sa 100 kg N/ha, a aktinomiceta sa 150 kg N/ha.

AB  - The paper studied the effects of different nitrogen rates (0, 30, 60, 90 kg N/ha) on the soybean cultivar Proteinka, inoculated with the NS-Nitragin microbial fertilizer. Trials were set up at Backi Petrovac on a soil with no previous history of soybean cultivation. Samples of plant material were taken twice, once at soybean flowering and once at maturity. At flowering, the largest mass and length of the above-ground plant parts were recorded in the treatment with 60 kg N/ha, while the largest nodule number, mass and N content were obtained with 30 kg N/ha. The largest pod, grain numbers and grain mass and N content were produced by the inoculated treatment with no N added, and chat was the treatment that produced the largest yield as well.
