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  - The dynamics of phosphorus and sulphur in soil is closely related to the dynamics of the biological cycle in which microorganisms play a central role. There is not much microbiological activity in acid soils because aerobes are scarce, rhizosphere is restricted to the shallow surface layer, and the biomass of microorganisms decreases with higher acidity. The aim of the research was to investigate the number of microorganisms, which decompose organic and inorganic phosphorus compounds and organic sulphur compounds in calcocambisol, luvisol, and pseudogley. The following parameters were determined in the soil samples: pH in H2O and in 1MKCl; the content of CaCO3 (%); humus content (%), nitrogen content (%); the content of physiologically active phosphorus and potassium (mg P2O5/100g of soil; mg K2O/100g of soil). The number of microorganisms was determined by the method of agar plates on appropriate nutrient media: the number of microorganisms solubilizing phosphates on a medium by Muramcov; the number of microorganisms that decompose organic phosphorus compounds on a medium with lecithin; and the number of microorganisms that transform organic sulphur compounds on a medium by Baar. All three types of soil are acid non-carbonate soils with a low level of available phosphorus and a more favorable amount of potassium, nitrogen, and humus. The largest number of bacteria, which transform organic phosphorus compounds, was found in calcocambisol. The largest number of phosphate solubilizing bacteria was recorded in pseudogley, whereas the largest number of phosphate solubilizing fungi was recorded in calcocambisol. The largest number of bacteria, which transform organic sulphur compounds, was recorded in pseudogley.

AB  - Microorganisms are involved in the formation of soil fertility, both potential and effective. They facilitate the processes of humification and dehumification and play a key role in the cycling of nutrients - macro and microelements. Rhizosphere is the soil in direct contact with plant roots and influenced by plant exudates. Root exudates of maize significantly affect the composition and abundance of microorganisms in the rhizosphere. Bio-fertilizers are microbial fertilizers composed of highly effective strains of bacteria, algae and fungi isolated from soil. Their application activates microbial processes that secure a better and steadier supply of plants with nitrogen, phosphorus, potassium and some micronutrients. The application of PGPR-containing biofertilizers reduces the need for expensive nitrogen fertilizers, facilitates phosphorus uptake by plants and affects the direction and dynamics of microbial processes.

Primenom biofertilizatora koji sadrže rizobakterije promotore biljnog rasta - PGPR (Plant Growth Promoting Rhizobacteria) smanjuje se upotreba skupih azotnih đubriva, omogućava se biljci lakše usvajanje fosfora i utiče na pravac i dinamiku mikrobioloških procesa.",

AB  - Attempts to produce food of plant origin without the use of fertilizers and pesticides are progressively becoming more numerous. It was also found that microorganisms have the ability to provide plants with necessary nutrients. Biofertilizers are expected to take an important place in agricultural production in the years to come. To produce quality biofertilizer, it is necessary to thoroughly study the microorganisms, their relationships, and relationships between organisms and crops for which the biofertilizer is intended. In the present study, we observed the effect of bean treatment with rhizobacteria on the soil microbial status and bean development and yield. A trial was established at Institute of Field and Vegetable Crops, Novi Sad. The inoculants came from the Faculty of Agriculture, Novi Sad. They had been developed from bean rhizosphere and tested in laboratory conditions prior to this study. Bean seeds were inoculated directly before sowing using 10 ml of inoculum per 100 g of seed. The following treatments were tested: 1. Rhizobium leguminosarum bv. phaseoli; 2. Azotobacter chroococcum; 3. Rhizobium leguminosarum bv. phaseoli + Azotobacter chroococcum + Streptomyces sp.; and 4. control (no inoculation). Plant material and rhizosphere soil were sampled at flowering and at full maturity. The rhizosphere soil was analyzed for total microbial abundance, the numbers of fungi, actinomycetes, aminoheterotrophs, azotobacter, and dehydrogenase activity as an indicator of the overall soil microbial activity. At full flowering, the effects of inoculation on the length of the above-ground plant part and root length were assessed. At full maturity, pod number, grain number and grain weight per plant were determined. The results of the study showed that inoculation effect depended on the type of inoculant, i.e., on interactions among the microorganisms used.

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  - This paper shows the results of analysis of soil compaction influence on sunflower yield on headland and inner part of a field, and chemical changes in soil. Soil compaction after sprouting was 67.70% greater on headland than in the inner part, while before harvesting, there was an increase of 13.44% in soil compaction. Large number of passages, which caused intensified soil compaction on headlands, poor conditions for the root system development, and poor microbiological activities led to yield reduction, which was 8.98% in total mass and 9.13% in dry grain mass. Chemical analysis of soil on headland and in the inner part of a field showed almost the same humus, nitrogen and other microelements concentration on headlands and in the inner part of a field. The total number of microorganisms is larger in the inner part of the field, while the number of actinomycetes is larger on headland. There are no significant differences in numbers of nitric bacteria and fungus.

AB  - This paper shows the results of analysis of soil compaction influence on sunflower yield on headland and inner part of a field, chemical and biological changes in soil. During the 5 years investigation, soil compaction after sowing was 23.01% greater on headland than in the inner part, while before harvesting, there was an increase of 28.43% in soil compaction.

AB  - This paper shows the results of analysis of soil compaction influence on sunflower yield on headland and inner part of a field, and chemical changes in soil. Soil compaction after sprouting was 67.70 % greater on headland than in the inner part, while before harvesting, there was an increase of 13.44 % in soil compaction. Large number of passages, which caused intensified soil compaction on headlands, poor conditions for the root system development, and poor microbiological activities led to yield reduction, which was 8.98% in total mass and 9.13% in dry grain mass. Chemical analysis of soil on headland and in the inner part of a field showed almost the same humus, nitrogen and other macroelements concentration on headlands and in the inner part of a field.

AB  - The investigation included examining the effect of soil compaction, soil depth and vegetation period on the number of microorganisms in soil covered with wheat. The soil samples were taken twice during the vegetation period (March, June 2007) from the depths of 0-30cm and 30-50cm, both from the central (loosing) and compacted parts of the lot. With all groups of microorganisms, apart from fungi and oligonitrophyls, the greatest number was observed in the central part of the lot. All groups of microorganisms were more abundant in ploughing layer of soil (0-30cm). The total number of microorganisms, ammonifiers, actinomycetes and oligonitrophyls was greater at the beginning of the vegetation period, whereas the total number of fungi and azotobacter was greater at the end of the vegetation period.

Kod svih grupa mikroorganizama, osim kod gljiva i oligonitrofila, brojnost je bila veća u centralnom delu parcele.Sve grupe ispitivanih mikroorganizama su bile brojnije u oraničnom sloju zemljišta (0-30 cm). Ukupan broj mikroorganizama, amonifikatora, aktinomiceta i oligonitrofila bio je veći na početku vegetacije, a gljiva i azotobaktera na kraju vegetacije.

AB  - Chernozem is a soil with ideal physical and chemical properties for crop production. When it comes to potato production, however, it has several drawbacks. One of the characteristics of chernozem is that it is a climatogenic soil, i.e. a soil of the semiarid climate. Such a climate is not optimal for potato growing, which requires a lot of precipitation. i.e. a humid climate. Also, the relief, being the third most important pedogenetic factor behind climate and the climate-dependent vegetation, makes chernozem a soil of flat terrains situated at low altitudes and thus precludes its use in the production of virus-free seed potatoes. Potato produces high and stable yields when grown on soils with good natural fertility under favorable climatic conditions. Weather conditions in the area of KO Maglić are those of a continental climate with a mean annual air temperature of 11.0 °C and a mean annual air temperature during the growing season of 17.6 °C. Relative humidity is 77.0%, total annual hours of daylight 2,034, and the winds most commonly blow from the northwest and the southeast (košava). The precipitation pattern is typically central European, with the most precipitation occurring in early summer (84.9 mm in June) and the least either in early spring (38.7 mm, March) or mid-fall (39.4 mm, October). Still, even on the best of soils developed under natural conditions, there is always some limiting factor that will cause yield losses relative to the genetic potentials of a given crop species. The present paper offers a brief overview of the soil properties at the KO Maglić site, where potato has been grown successfully for decades.
AB  - U okviru projekta "Karakterizacija i uređenje zemljišta za proizvodnju krompira", koji je u periodu 2002-2005. godine finansiralo Ministarstvo za nauku i životnu sredinu Republike Srbije, izvršeno je ispitivanje obradivog zemljišta na lokalitetima u Vojvodini i centralnoj Srbiji koji se tradicionalno koriste za proizvodnju krompira. Prikazani su rezultati sa DP PD "Maglić" iz Maglića koji na zemljištu tipa černozem, na površini od oko 250 ha, proizvode krompir koji se prerađuje u "MARBO PRODUCT" d.o.o. iz Maglića. Černozem na području Bačke ima povoljan vodno-vazdušni režim autoregulacionog karaktera. Ima veliku infiltracionu moć, a istovremeno zahvaljujući dobroj strukturi ima vrlo povoljnu vodosprovodljivost, koja omogućuje da se zemljište brzo oslobađa suvišne vode. Pored visokoproizvodnih osobina zapaženo je da černozem daje neujednačene i varijabilne prinose. Oscilacije u visini prinosa su uzrokovane sušom jednostranim korišćenjem. nedovoljnom agrotehnikom. Zato i na čemozemu treba sprovoditi kompleksne agrotehničke mere uključujući i navodnjavanje, što obezbeđuje da ovo zemljište hude najviših proizvodnih sposobnosti. Ispitivano zemljište ima optimalnu količinu humusa i ukupnog azota u većini uzoraka i treba ih održavati redovnim đubrenjem organskim đubrivima i zaoravanjem žetvenih ostataka. Dobra obezbeđenost zemljišta ukupnim azotom i lako pristupačnim fosforom i kalijumom, omogućava u uslovima sa dovoljno vlage ostvarivanje visokih prinosa. Najbolji prinosi krompira se postižu na zemljištima lakšeg mehaničkog sastava, dobre i stabilne strukture, odnosno zemljištima koja imaju dobar vodni, vazdušni i toplotni režim, što je utvrđeno na uzorcima sa ovog terena. U pogledu hemijskih svojstava, krompir podnosi hemijsku reakciju zemljišta od pH 4,5 do pH 7.5 međutim, najveći prinosi krompira se ostvaruju na neutralnim zemljištima koja su dobro obezbeđena biogenim makro i mikroelementima u pristupačnim oblicima. Ispitivanja ukupnog sadržaja mikroelemenata i štetnih elemenata u zemljištu na lokalitetima na kojima se tradicionalno proizvodi krompir ne postoji opasnost da ovi teški metali preko biljaka uđu u lanac ishrane, kao ni da usled ispiranja zagade nadzemne i podzemne vode jer su daleko ispod dozvoljenih sadržaja (MDK). Iz tog razloga dobra je i mikrobiološka aktivnost u zemljištu kao i brojnost ispitivanih grupa mikroorganizama, tako da su i po tim parametrima ova zemljišta izuzetno pogodno za ostvarivanje visokih i stabilnih prinosa krompira, dobrog kvaliteta. Generalno se može zaključiti da uzorci zemljišta sa lokacija u Magliću ne ukazuju na povećanje radioaktivnosti koje bi ugrozilo proizvodnju hrane. Izmerene koncentracije aktivnosti l37Cs, uzimajući u obzir transfer faktore ovog izotopa u biljke ne bi trebalo da ugroze zdravstvenu bezbednost proizvedene hrane.

There are more and more genetically modified plant species such as soybean, corn, potato, rice and others and there is a pressure to use them as human food and animal feed.

AB  - Microorganisms are widely spread around nature in the soil, water and air as well as on plants and animals and are a crucial link in the chain of matter circulation on the planet. They are the most important component of the biological soil phase and an important indicator of soil fertility and soil degradation. Soil microbiological processes are dependant on the organic matter content, while the fertility of a given soil type is connected with the activity of its microflora. Knowing the metabolism of a microorganism enables the direction of microbiological processes by application of useful microorganisms to maintain and enhance soil biological activity, i.e. soil biogenicity. An increase of acreage in legumes requires that a wider use of microbiological fertilizers to maintain and increase soil fertility be considered. Results of legume nitrogen fixation suggest that fixed nitrogen makes a large annual contribution to yield, which justifies the use of highly effective strains in microbiological fertilizers, enables the replacement of nitrogen from mineral fertilizer with biological nitrogen and has economic and environmental effects as well. The incorporation of microorganisms causes no soil pollution, reduces the use of mineral nitrogen fertilizer, contributes to the production of environmentally safe food improves the soil structure, increases the organic matter content and positively affects physical soil properties.
AB  - Mikroorganizmi su široko rasprostranjeni u prirodi u zemljištu, vodi vazduhu, na i u biljkama i životinjama i oni su nezaobilazna karika u kruženju materija na našoj planeti. Najznačajnija komponenta biološke faze zemljišta su mikroorganizmi koji su važan indikator plodnosti i procesa degradacije zemljišta. Mikrobiološki procesi u zemljištu uslovljeni su sadržajem organske materije, a plodnost svakog tipa zemljišta je vezana sa aktivnošću njene mikroflore. Poznavanjem metabolizma mikroorganizama, mogu se usmeriti mikrobiološki procesi tako što će se primenom korisnih mikrooragizama održati i poboljšati biološka aktivnost, odnosno biogenost zemljišta. Širenje površina pod leguminozama zahteva razmišljanje o široj primeni mikrobioloških đubriva u cilju očuvanja i povećanja plodnosti zemljišta. Rezultat azotofiksacije leguminoznih biljaka pokazuje da je godišnji udeo fiksiranog azota u prinosu veliki, što opravdava primenu visokoefektivnih sojeva u mikrobiološkim đubrivima, omogućuje zamenu azota iz mineralnog đubriva biološkim azotom, a ima i ekonomski i ekološki efekat. Unetim mikroorganizmima ne zagađuje se zemljište, smanjuje se upotreba mineralnih azotnih đubriva, doprinosi proizvodnji ekološki zdrave hrane poboljšava struktura zemljišta, povećava sadržaj organske materije i pozitivno utiče na fizičke osobine zemljišta.
