AB  - The purpose of this study is to examine the effects of different Trichoderma spp. treatments (T1: Trichoderma harzianum, T2: Trichoderma brevicompactum, and T3: T1 + T2) on two tomato cultivars (‘Narvik’ and ‘Gružanski zlatni’) by the non-destructive monitoring of chlorophyll (Chl) and epidermal flavonol (Flav) indices and nitrogen balance index (NBI) in their leaves. The main objectives were to compare the responses of tomato cultivars considered (grown in a greenhouse) to different Trichoderma strains and a combination of Trichoderma strains. Variations in the Chl, Flav, and NBI values obtained were significantly influenced by nearly all the factors examined (namely the tomato cultivar, experimental week, and treatment), the interaction of which was found significant for all the parameters analyzed. The results obtained indicate that the combinations of strains in the T3 treatment markedly enhanced the Chl content in the ‘Narvik’ cultivar in some experimental weeks. Moreover, reduced NBI values were determined in the Trichoderma-treated ‘Narvik’ plants due to the increased flavonol content, which indicates a shift from primary to secondary metabolism. Further research, including the same cultivars and treatments, is warranted under field conditions to evaluate the physiological responses of the ‘Narvik’ and ‘Gružanski zlatni’ tomato cultivars in a multiple-stressor environment.

AB  - Due to strict rules in ecological plant production, especially in
case of fertilization and plants protection, productivity i. e. yield could be
limited. Choosing the appropriate genotypes, modest requirements to the inputs
and adapted to the conditions of ecological cultivation is a particularly
important point and one of the prerequisites for economical, profitable and
stable production, without big risks and losses. The aim of this paper was to
estimate adaptability of wheat genotypes to ecological growing conditions
according to grain yield. The trial was carried out in Center for Small Grains,
Kragujevac, Serbia. 23 Serbian wheat genotypes were included. There were
applied two fertilization variants (manure and NPK fertilizers) and control
one, too. Mainly, NPK fertilizers caused statistically significant differences in
grain yield. At the same time, manure influenced the increase of grain yield
compared to the control variant. The genotypes that achieved similar yields,
without significant differences in relation to applied fertilizers, were: Morava,
Lepenica, Studenica, KG 100, Lazarica, Pobeda, Evropa 90, Perla, Pesma.
Vizija was the more yielding in manure than in NPK variant. Those varieties
are interested for practical cultivation in ecological agriculture and could be
significant material in wheat breeding in order to obtain new varieties adapted
to the ecological system of cultivation and sustainable agriculture.

AB  - Maize is one of the most important cereal crops. Besides its use as food
and feed, maize is also an energy crop. In order to ensure sufficient quantities of
maize, the main goal of every breeding program is to develop new, better hybrids.
Correlation and path coefficient analysis can be used for indirect selection of highyielding
hybrids. In light of that, one of the objectives of this paper was to determine
relationship between grain yield and morphological traits, for 8 inbred lines and their
hybrids, Strong genetic and phenotypic correlations were found between grain yield
and other studied traits, except between grain yield, on one side, and kernel row
number, where we found medium phenotypic correlations, Between morphological
traits of plant and ear the highest values of genotypic and phenotypic coefficient of
correlations were found between ear length and kernel number per row. Also, the
objective of this research was to find the direct and indirect effects of morphological
traits on grain yield. Desirable, high significant influence on grain yield in path
coefficient analysis, was found for almost all studied traits. Ear height was the only
trait that had negative direct genetic and phenotypic influence.

AB  - Soil pollution with heavy metals is a serious threat to the environment. However, soils polluted with heavy metals are considered good sources of native metal-resistant Trichoderma strains. Trichoderma spp. are free-living fungi commonly isolated from different ecosystems, establishing endophytic associations with plants. They have important ecological and biotechnological roles due to their production of a wide range of secondary metabolites, thus regulating plant growth and development or inducing resistance to plant pathogens. In this work we used indigenous Trichoderma strains that were previously isolated from different soil types to determine their tolerance to increased copper and nickel concentrations as well as mechanisms of metal removal. The concentrations of bioavailable metal concentrations were determined after extraction with diethylene-triamine pentaacetate (DTPA)-extractable metals (Cd, Cr, Co, Cu, Pb, Mn, Ni, and Zn) from the soil samples by inductively coupled plasma-optical emission spectrometry (ICP-OES). Two indigenous T. harzianum strains were selected for copper tolerance, and three indigenous T. longibrachiatum strains were selected for nickel tolerance tests. Strains were isolated from the soils with the highest and among the lowest DTPA-extractable metal concentrations to determine whether the adaptation to different concentrations of metals affects the mechanisms of remediation. Mechanisms of metal removal were determined using Fourier-transform infrared spectroscopy (FTIR) and X-ray fluorescence spectroscopy (XRF), non-destructive methods characterized by high measurement speed with little or no need for sample preparation and very low costs.

abstract = "Soil pollution with heavy metals is a serious threat to the environment. However, soils polluted with heavy metals are considered good sources of native metal-resistant Trichoderma strains. Trichoderma spp. are free-living fungi commonly isolated from different ecosystems, establishing endophytic associations with plants. They have important ecological and biotechnological roles due to their production of a wide range of secondary metabolites, thus regulating plant growth and development or inducing resistance to plant pathogens. In this work we used indigenous Trichoderma strains that were previously isolated from different soil types to determine their tolerance to increased copper and nickel concentrations as well as mechanisms of metal removal. The concentrations of bioavailable metal concentrations were determined after extraction with diethylene-triamine pentaacetate (DTPA)-extractable metals (Cd, Cr, Co, Cu, Pb, Mn, Ni, and Zn) from the soil samples by inductively coupled plasma-optical emission spectrometry (ICP-OES). Two indigenous T. harzianum strains were selected for copper tolerance, and three indigenous T. longibrachiatum strains were selected for nickel tolerance tests. Strains were isolated from the soils with the highest and among the lowest DTPA-extractable metal concentrations to determine whether the adaptation to different concentrations of metals affects the mechanisms of remediation. Mechanisms of metal removal were determined using Fourier-transform infrared spectroscopy (FTIR) and X-ray fluorescence spectroscopy (XRF), non-destructive methods characterized by high measurement speed with little or no need for sample preparation and very low costs.

AB  - Background The Republic of Serbia (RS) is strategically oriented towards sustainable development, but the imple mentation thereof faces diferent limitations and problems. RS emits substantial pollution caused by fossil fuels, and pollution from agricultural sector characterized by inefcient use of energy and intensive use of fertilizers. Bearing in mind the signifcant agricultural capacities and the orientation towards rural development, a special green transformation must be implemented in this domain. Taking into account the specifcities and tradition, the introduction of the circularity concept can be considered the most acceptable. Research on readiness for transition to circular ity in RS rural areas has not been conducted; therefore, the goal of the paper is to develop a concept for assessing the capacity of rural areas for circularity. This study is the frst scientifc proposal that aims to provide input for poli cymakers, thus contributing to the creation of a new identity of RS, whose development is based on the principles of sustainability.
Methods The study was conducted as conceptual research, with the objective of examining an undiscovered phe nomenon without empirical evidence and incorporating the targeted phenomenon into a conceptual framework, while providing a proposal for a solution model based on an interdisciplinary approach—the application of qualita tive and quantitative methods (aggregation of composite indicators and Delphi method).
Results Paper results can be summarized as follows: (a) qualitative analysis of policy framework related to RS transi tion towards circularity (which shows that regulation is insufcient or non-existent, so conceptual research at this stage is necessary and only possible); (b) research questionnaire; (c) original set of indicators for measuring capacity for circularity (derived from the questionnaire); (d) concept of index of capacity of agriculture and rural areas for circu larity (based on a set of indicators); and (e) concept of the monitoring of circularity implementation.
Conclusions The main research fndings presented in this paper could be benefcial for countries at early stages of introducing circularity, having both low and high agricultural potential. With slight modifcations, they can also be applied to other economic activities

AB  - Fruits of Sorbus torminalis L. Crantz. (Wild service tree) have been traditionally used, fresh or dried, for
the production of preserves such as jam, jelly, syrup, compote or tea. Furtheremore, these fruits are well
known worldwide as a traditional remedy for treating respiratory tract infections, as traditional astringent,
diarrheic and antidiabetic agents. As a part of broad research, the aim of this study was to define phenolic
profile as well as antioxidant activity of water and methanolic extracts of dried fruits. The presence and
content of 44 plant phenolics and quinic acid was determined using LC-MS/MS technique. In order to
examine antioxidant potency, few in vitro assays were carried out: DPPH. (diphenylpicrylhydrazyl), HO»
(hydroxyl radical), and reducing power (FRAP) assay. In addition, total phenolic and flavonoid contents were
determined spectrophotometrically. Among examined compounds, quinic acid (precursor of phenolics) was
the most dominant among both samples. Moreover, protocatechuic an ferulic acids were the most abundant
amongst phenolics acids. Furthermore, analysis of selected flavonoids showed notable content of
amentoflavone as well as quercetin glycosides (quercetin-3-O-glucoside and hyperoside). In applied
antioxidant tests, methanolic extract showed the highest antiradical activity. Compared to propyl galate, a
well known synthetic antioxidant, both extracts exhibited a potent antioxidant activity. Total phenolic content
was significant, expecially in methanolic extract, while total phenolic content was low in both extracts.
Obtained results indicates a significant antioxidant potential of S. torminalis fruits and higly support
traditional use of this species in diet, but also points to its use as a functional food.

AB  - Selection of the best breeding technique for the development of new maize
hybrids is based on knowledge of gene effects type responsible for the
expression of quantitative traits. Thus, the goal of this study was to evaluate
gene effects on the grain yield, as the most important agronomic trait, as
well as for kernel oil content. one of the major characteristics of maize
quality.
Genetic material used for the determination of gene effects consisted of
four inbred lines: 1109/1V NS, 56811 NS, 922 NS and A-l. Inbred line
1109/1V NS is high oil inbred line, and 568/11 NS, 922 NS A-1 are lines
with a different type of seed: dent, semi-dent and flint, respectively. Six
basic generations were produced: parental inbred lines (Pi, Pa), first and
second filial generations (Fy, F2) and backcross generations (BC), BC2).
Two years experiment was performed at the experimental field of the
Institute of Field and Vegetable Crops, Novi Sad, Serbia (Rimski Sangevi)
using a completely randomized design with eight replicates. Evaluation of
gene effects was performed by generation mean analysis.
Obtained results indicated that dominant gene effect had a higher influence
than additive in inheritance of the grain yield. The significant presence of
duplicate type of epistasis was recorded in all test-cross combinations. For
kernel oil content dominance was more important than additive gene action
for almost all studied test-crosses. Additive gene effect was higher than
dominance only for hybrid 1109/IV NS = 56811 NS. Morcover, a
significant presence of duplicate type of cpistasis also was detected for
kernel oil content.
The significant role of the dominant gene effect in the inheritance of grain
vield and kernel oil content in almost all test-cross combinations indicates that inbreding-hybridization method is a useful method for the development of
better hybrids.

AB  - In cnhancing agricultural productivity, one of the most important
determinants is to choose the best fertilizer application system. Among
different application systems. fertigation can have multiple benefits on the
yield and quality of crops since it can significantly reduce costs and
increase the profitability. However. inadequate, excessive application of
fertilizers through fertigation and irrigation may lead to soil degradation
and deterioration of soil fertility. resulting in a change of some physical and
chemical parameters of soil. Thus, the aim of this study was to compare the
effect of fertigation and conventional fertilization on the soil chemical
characteristics.
The experiment was designed to determine the effect of two different ways
of fertilizer application (through two treatments: drip irrigation systemfertigation
and classical way) and three different doses of NPK fertilizers
on chemical parameters of chernozem soil type. in a modern apple (Red
Jonaprince variety) orchard. From cach treatment. bulk soil samples were
taken for the determination of soil pH, mineral nitrogen (N), readily
available potassium (K:0) and phosphorus (P20s). Samples were collected
in the spring, before fertilizer application, to determine the initial soil
condition and in the autumn, at the end of the vegetation period.
The pH in H:0 when the highest dose of fertilizer was applied by
fertigation had a significantly lower value compared to the control. while in
classical fertilization all three doses implicated a decrease of pH value
compared to the control. The results showed that different doses of
fertilizers significantly affected the content of N, K:O and P:0s.
Furthermore, the obtained results were strongly affected by meteorological
conditions, because in some months the application of irrigation was not necessary, due to a large amount of precipitation. To conclude, these results
could serve as an indicator for further analysis of soil impact on yield and
quality of apple fruit.

Фертиригација је поступак који обједињује ове две агротехничке мере, чиме се остварује значајна уштеда у употреби ђубрива и смањују губици нитратних облика азота. За остваривање високих приноса доброг квалитетна неопходна је адекватна примена ђубрива. Из тог разлога, један од циљева овог рада је био испитивање различитих доза минералних ђубрива на компроненте приноса и принос јабуке. Такође, циљ овог истраживања је био и утврђивање оптималнијег начина уношења хранива.
МАТЕРИЈАЛ и МЕТОД: Како би се испитао утицај различитих доза ђубрива и начина примене ђубрива на принос и компоненте приноса јабуке постављен је оглед у засаду јабуке Red Jonaprince на огледном пољу Департмана за воћарство, виноградарство, хортикултуру и пејзажну
архитектуру на Римским Шанчевима. Оглед је постављен по систему подељених парцела. Примењенe су три различите дозе ђубрива: N1P1K1 – 50 kg/ha N, 30 kg/ha P2O5, 60 kg/ha K2O;
N2P2K2 – 100 kg/ha N, 59.8 kg/ha P2O5, 100 kg/ha K2O; N3P3K3 – 150 kg/ha N, 80.6 kg/ha P2O5, 140
kg/ha K2O. Апликација хранива урађена је класичним начином и фертиригацијом крот систем за наводњавање кап по кап. Анализиране су следеће особина: број плодова по стаблу, просечна маса плодова и принос плода по стаблу. Мерења су урађена на по 10 стабала по сваком понављању, а просечна маса плодова је утврђена на основу 10 плодова по стаблу. Анализа варијансе урађена је по моделу подељених парцелана на основу средњих вредности. Поређење средњих вредности
урађено је применом LSD теста. Статистичка обрада података урађена је у програму Statistic.
РЕЗУЛТАТИ и ЗАКЉУЧЦИ: Највећи број плодова по стаблу остварен је применом највеће дозе NPK хранива фертиригацијом. Број плодова по стаблу услед примене овог третмана био је статистички значајно виши у односу на контролу и најмању проимењену дозу хранива. При
класичном начину примене минералних ђубрива ни једна доза ђубрива није значајно утицала на повећање броја плодова по стаблу. За другу проучавану особину, просечна маса плодова, при класичном начину примене ђубрива највећа вредност измерена је при примени најмање дозе хранива, и она се статистички значајно разликовала од контроле. За други примењен третман, фертиригацију, највећа вредност за ову особину установњена је при примени највеће дозе минералних хранива, и она је била статистички значајно већа у односу на контролу и друге две дозе хранива. Највећи принос остварен је третманом N3P3K3 примењеног фертиригацијом и статистички се значајно разликовао само у односу на контролу и третман N1P1K1 примењен
фертиригацијом, док у односу на остале примењене третмане није забележена статистички значајна разлика. Иако анализом варијансе није установњена статистичка значајност између примењених начина ђубрења, више средње вредности за скоро све проучаване особине установљене су применом фертиригације. Како истовремена примена наводњавања и ђубрива повећава ефикасност коришћења хранива и воде, уз значајну уштеду ресурса и смањење
контаминације земљишта, односно животне средине, примена фертиригације пружа велике могућности за оптимално решење најзначајнијих мера гајења јабуке.
AB  - INTRODUCTION and OBJECTIVES: In modern apple orchards, fertilization and irrigation are
among the most important agrotechnical measures on which growth and yield depend. Fertigation is a
process that combines these two agrotechnical measures, providing significant savings in the use of
fertilizers and reducing losses of nitrate forms of nitrogen. Adequate application of fertilizers is
necessary to achieve high and good quality yields. For that reason, one of the goals of this study was to
examine application of different doses of fertilizers on yield components and apple yield. Also, the aim
of this research was to determine a more optimal way of nutrient intake.
MATERIAL and METHOD: In order to examine the effects of fertilization rate and methods on apple
yield and yield component, an experiment was set up in apple orchard in the experimental field of the
Department of Fruit Growing, Viticulture, Horticulture and Landscape Architecture on Rimski San&evi.
Apple variety was Red Jonaprince, and experiment was arranged in split plot design with three
replications. Three different fertilizer doses were applied: N1P1K1 — 50 kg/ha N, 30 kg/ha P,Os, 60
kg/ha K,0; N2P2K2 — 100 kg/ha N, 59.8 kg/ha P,Os, 100 kg/ha K;0O; N3P3K3 — 150 kg/ha N, 80.6
kg/ha P,Os, 140 kg/ha K,0. The nutrients application was done by drip irrigation system — fertigation
and classical way. The following traits were analyzed: fruit number per tree, average fruit weight and
fruit yield per tree. The data for fruit number per tree and fruit yield per tree was recorded from 10
randomly chosen trees, and average fruit weight was determined on the basis of 10 fruits per tree per
replications. Analysis of variance was done according to the split-plot design based on mean values. The
comparison of mean values was done using the LSD test. For data processing software Statistic was
used.
RESULTS and CONCLUSIONS: The largest fruit number per tree was recorded when the highest
dose of NPK nutrients was applied by fertigation. It was significantly higher than mean value of fruit
number per tree on control plots and on plots when the lowest NPK dose was used. Classical way of
using fertilizers didn't significantly affected fruit number per tree. For the second studied trait, average
fruit weight, in classical way of fertilizer application, the highest mean value was recorded with the
lowest dose of NPK fertilizers. It was significantly different from the control. When fertilizer was
applied by fertigation, the highest mean value for this trait was found for the highest doses of NPK
nutrients. This mean value was significantly higher compared to the control and other two doses of
fertilizers. The highest fruit yield per tree was achieved with the treatments of N3P3K3 applied by
fertigation. It was statistically significantly different only in relation to the control and treatment of
N1PIK1 applied by fertigation. Although ANOVA did not establish statistical significance between the
applied fertilization methods, higher mean value for almost all studied traits were established using
fertigation. As the simultaneous application of irrigation and fertilizers increases the efficiency of
nutrient and water use, with significant savings of resources and reduction of soil and environmental
contamination, the application of fertigation provides greater opportunities for optimal solutions to the
most important agrotechnical measures of apple growing

AB  - The influence of different groundwater table depths on pre-dawn water potential (PWP), soil moisture content and antioxidant activity (FRAP, RSC against DPPH·, NO and ABTS radicals) of adult pedunculate oak (Quercus robur L.) trees was assessed in three managed stands (localities 1-3) and one unmanaged (locality 4 - forest reserve). The study sites were located within single forest complex at different distances from the Sava riverbed. The measurements were performed during July 2015, when the first evidence of drought was evidenced. We hypothesised that the trees at locations farther from the river would be more drought-stressed due to lower groundwater depth and will show higher antioxidant capacity. Indeed, trees at localities 2 and 3 were more drought-stressed as compared to trees at locations 1 and 4, as indicated by the PWP results. Since antioxidant capacity can be directly correlated to drought tolerance, the present results
indicate a higher antioxidant capacity in leaf extracts from locality 3, but also good oxidative adaptation in leaf extracts from locality 4, where the obtained values for almost all examined antioxidant tests were without statistically significant differences compared to those on locality 3. Obtained results may help to explain differences in biochemical responses to water deficit stress of pedunculate oak trees from different microsites within the single forest complex and provide us
valuable information about intra-species drought resistance. Therefore, this can be an important tool for the improvement of breeding strategies and artificial regeneration plans for pedunculate oak in dry lowland regions.

AB  - Biofertilizers have great potential to improve crop yields through environmentally save mechanisms. Fungi of the genus Trichoderma, as potential components of biofertilizers, have a positive effect on plant growth and inhibit the growth of pathogenic microorganisms through several antagonistic mechanisms. In this study, commercially available tomato genotypes (Narvik and Gruzanski zlatni) and strains of two Trichoderma species (T. afroharzianum SZMC 25231 and T. rodmanii SZMC 25217) were selected to examine the effects of Trichoderma spp. on morpho-physiological parameters of tomato plants grown under organic production system.
The experiment was conducted in a randomized block design under greenhouse conditions. In total, 15 plants of two tomato cultivars per treatment were transplanted in soil: NC – control Narvik, GZC – control Gruzanski zlatni, NT1 – T. afroharzianum; NT2 – T. rodmanii; GZT1 – T. afroharzianum; GZT2 - T. rodmanii. The suspensions of Trichoderma isolates were applied in the root zone of tomato plants in the phase of four established leaves. Measurements of relative chlorophyll (Chl), flavonol (Flav) and anthocyanin (Ant) content were performed in vivo on fully developed leaves of the tomato plants using Dualex optical sensor (Force-A, Orsay, France). NBI (Nitrogen Balance Index) was calculated as Chl/Flav ratio. Plant height was measured as a plant growth parameter. Measurements were performed once per week during 35 days of plant growth (5 weeks) and conducted in 10 replications on 10 plants per treatment.
Compared to the control, significant increase of Chl and Flav content was observed on genotype GZ after treatment with both Trichoderma species in the 3rd and 4th week, which resulted in decreased value of the NBI. Also, for the same genotype, Trichoderma positively affected plant height. On the other hand, combination of Trichoderma and genotype Narvik hasn’t showed stimulative effect on examined morpho-physiological parameters. These results indicated genotype-species dependence of tomato-Trichoderma interaction.
The obtained results indicate that non-destructive measurements with Dualex sensor could serve as starting point to better understand plant responses to Trichoderma presence.

abstract = "Biofertilizers have great potential to improve crop yields through environmentally save mechanisms. Fungi of the genus Trichoderma, as potential components of biofertilizers, have a positive effect on plant growth and inhibit the growth of pathogenic microorganisms through several antagonistic mechanisms. In this study, commercially available tomato genotypes (Narvik and Gruzanski zlatni) and strains of two Trichoderma species (T. afroharzianum SZMC 25231 and T. rodmanii SZMC 25217) were selected to examine the effects of Trichoderma spp. on morpho-physiological parameters of tomato plants grown under organic production system.
The experiment was conducted in a randomized block design under greenhouse conditions. In total, 15 plants of two tomato cultivars per treatment were transplanted in soil: NC – control Narvik, GZC – control Gruzanski zlatni, NT1 – T. afroharzianum; NT2 – T. rodmanii; GZT1 – T. afroharzianum; GZT2 - T. rodmanii. The suspensions of Trichoderma isolates were applied in the root zone of tomato plants in the phase of four established leaves. Measurements of relative chlorophyll (Chl), flavonol (Flav) and anthocyanin (Ant) content were performed in vivo on fully developed leaves of the tomato plants using Dualex optical sensor (Force-A, Orsay, France). NBI (Nitrogen Balance Index) was calculated as Chl/Flav ratio. Plant height was measured as a plant growth parameter. Measurements were performed once per week during 35 days of plant growth (5 weeks) and conducted in 10 replications on 10 plants per treatment.
Compared to the control, significant increase of Chl and Flav content was observed on genotype GZ after treatment with both Trichoderma species in the 3rd and 4th week, which resulted in decreased value of the NBI. Also, for the same genotype, Trichoderma positively affected plant height. On the other hand, combination of Trichoderma and genotype Narvik hasn’t showed stimulative effect on examined morpho-physiological parameters. These results indicated genotype-species dependence of tomato-Trichoderma interaction.
The obtained results indicate that non-destructive measurements with Dualex sensor could serve as starting point to better understand plant responses to Trichoderma presence.",

AB  - INTRODUCTION:
Fungi that belong to the genus Trichoderma colonize plant rhizosphere and are considered as good candidates for the use
in environmentally friendly agriculture as plant growth promoters and biocontrol agents. In recent years, investigations are
focused on the use of non-destructive characterization of plant responses to different abiotic and biotic stresses.
OBJECTIVES:
Dualex sensor was used in order to pre-screen the reaction of tomato plants treated with different Trichoderma isolates,
based on the previous investigations that imply that the positive effects of this fungi depend on the plant genotype.
METHOD / DESIGN:
The experiment was conducted in a randomized block design under greenhouse conditions with two replicates. In total 30
plants of two tomato cultivars were transplanted in soil, per treatment: NC-control Narvik, GZC- control Gruzanski zlatni,
NT1 - T. harzianum; NT2 - T. brevicompactum; NT3 - T. harzianum + T. brevicompactum; GZT1 - T. harzianum; GZT2 - T. brevicompactum;
GZT3 - T. harzianum + T. brevicompactum). The suspensions of Trichoderma isolates were applied in the root zone
of tomato plants, in the phase of three established leaves per plant. Measurements of chlorophyll (Chl), flavonols (Flav) and
anthocyanins (Ant) content were done in vivo on fully developed leaves of the tomato plants, using Dualex optical sensor
(Force-A, Orsay, France), once per week during 50 days of plant growth. NBI (Nitrogen Balance Index) was calculated as Chl/
Flav ratio.
RESULTS:
Results obtained in this experiment showed that in both cultivars, the content of chlorophyll did not change significantly
after Trichoderma application. However, positive trend for Flav content was observed for the cultivar GZ in the treatment with
T2. In contrast, at the beginning of the experiment, NBI index decreased in GZ as influenced with T1 and T2 treatments, which
could indicate a shift from primary to secondary metabolism in mentioned cultivar. Moreover, it could be noticed that during
plant growth content of anthocyanin decreased in both control and Trichoderma treatment conditions.
CONCLUSIONS:
In conclusion, we can suggest that use of non-destructive measurements with Dualex sensor could serve as starting point
to better understanding of plant responses to Trichoderma presence. Moreover, measurements with Dualex can serve as
a pre-screening method for testing the effect of larger number of Trichoderma isolates and their effect on more different
tomato genotypes.

AB  - : Heavy metals in the environment when present in excess have negative effect on survival of plants
causing diminished physiological and molecular activities. As they are hard to degrade, their exchangeable fraction
is accumulated in plants and animals, thus entering the food chain. As one of the major concerns among
consumers worldwide is food safety, organic agriculture is a promising system for its preservation.
In this work we have examined soil samples from the plant rhizosphere grown in organic production system at 5
different locations: Gložani, Svilajnac, Čenej 1, Čenej 2 and Temerin, for metal presence and chemical
characteristics (soil acidity, humus content and free CaCO3 content). Determination of the total metal content ((As,
Cd, Cr, Co, Cu, Fe, Pb, Ni, Zn, Mn)) in soil samples was performed according to EPA 6010C method using
inductively coupled plasma-optima emission spectrometry (ISP-OES).
Results showed that the sampled soil is mainly of alkaline character,moderatly carbonate and rich in humus. The
content of metals, at all localities, did not exceed the maximum allowed concentrations for the following metals:
arsenic, cadmium, chromium, iron, manganese, nickel, lead and zinc. In the case of cobalt deviation from the MLC
value was observed in four samples. However, in the case of copper only one sample exceeded MDK value.
Presented results indicate that maintenance and regular soil quality control is necessary in both organic and
conventional agriculture

AB  - The effect of mulching on early potato yeald was investigated on two potato varieties, Cleopatra and Riviera.
The experiment was set up in three vegetation seasons at one locality (Begeč), according to the split-plot design with five
replications. Tuber number per plant, tuber weight per plant (g) and the yield (kg/ha) were analyzed. Analysis of variance
was performed according to the split-plot design based on average means. The comparison of mean values was done
using the LSD test. A highly significant effect of treatment was determined for all three studied traits. Both studied cultivars
achieved a significantly higher yield and tuber mass per plant when mulch was applied, while the trait tuber number per
plant was higher in the control variant (bare soil). Statistically significantly higher values for all three studied traits were
found in the Riviera variety. According to results, it can be concluded that the application of mulch has a positive impact on
the yield of early potato, which provides an opportunity for wider application of this specific agricutural measure in the

AB  - The short-term effects of Trichoderma harzianum on growth, content of chlorophyll and epidermal flavonols and metal distribution was examined in young tomato plants grown in the climate chamber. T. harzianum was applied near the root in the phase of sixth established leaves, and plants were grown in a growth cabinet up to the stage of 10 leaves. Trichoderma application positively affected growth of tomato plants, and significantly increased content of epidermal flavonols. Also, the significant decrease of Cd in all plant parts was observed. However, content of Cr and Ni was lower only in roots. The primary goal of the examination of the long-term effect of T. harzianum was the fruit quality of two commercial tomato cultivars grown in organic system of production in the field under polytunnel. One cultivar had a significant response to Trichoderma application. The increase of leaf epidermal flavonols was observed, however as the chlorophyll content decreased, the nitrogen balance index has also decreased, indicating a shift from primary to secondary metabolism. The fruit quality of the same cultivar was improved by increased total flavonoids content, decreased starch, increased Bioaccumulation Index (BI) for Fe and Cr, and decreased BI for heavy metals Ni and Pb. Data indicate that in some cultivars of tomato the interaction with Trichoderma contributes to improved health promoting properties of tomato fruit.

abstract = "The short-term effects of Trichoderma harzianum on growth, content of chlorophyll and epidermal flavonols and metal distribution was examined in young tomato plants grown in the climate chamber. T. harzianum was applied near the root in the phase of sixth established leaves, and plants were grown in a growth cabinet up to the stage of 10 leaves. Trichoderma application positively affected growth of tomato plants, and significantly increased content of epidermal flavonols. Also, the significant decrease of Cd in all plant parts was observed. However, content of Cr and Ni was lower only in roots. The primary goal of the examination of the long-term effect of T. harzianum was the fruit quality of two commercial tomato cultivars grown in organic system of production in the field under polytunnel. One cultivar had a significant response to Trichoderma application. The increase of leaf epidermal flavonols was observed, however as the chlorophyll content decreased, the nitrogen balance index has also decreased, indicating a shift from primary to secondary metabolism.

AB  - The beneficial role of fungi from the Trichoderma genus and its secondary metabolites in promoting plant growth, uptake and use efficiency of macronutrients and oligo/micro-nutrients, activation of plant secondary metabolism and plant protection from diseases makes it interesting for application in environmentally friendly agriculture. However, the literature data on the effect of Trichoderma inoculation on tomato fruit quality is scarce. Commercially used tomato cultivars were chosen in combination with indigenous Trichodrema species previously characterized on molecular and biochemical level, to investigate the effect of Trichoderma on photosynthetic characteristics and fruit quality of plants grown in organic system of production. Examined cultivars differed in the majority of examined parameters. Response of cultivar Gruzanski zlatni to Trichoderma application was more significant. As a consequence of increased epidermal flavonols and decreased chlorophyll, the nitrogen balance index in leaves has decreased, indicating a shift from primary to secondary metabolism. The quality of its fruit was altered in the sense of increased total flavonoids content, decreased starch, increased Bioaccumulation Index (BI) for Fe and Cr, and decreased BI for heavy metals Ni and Pb. Higher expression of swolenin gene in tomato roots of more responsive tomato cultivar indicates better root colonization, which correlates with observed positive effects of Trichodrema.

AB  - In this paper, the effects of bacterial isolates: Bacillus velezensis SZMC 24986, Pseudomonas resinovorans SZMC 25872 and Arthrobacter globiformis SZMC 25081 on two genotypes of Gružanski zlatni and Narvik tomatoes grown in a greenhouse were investigated. The reactions of the examined plants were monitored by quantification of morphometric (plant height, fresh and dry mass of the aboveground part of the plant and roots) and physiological (indices of chlorophyll, epidermal flavonols, anthocyanins and nitrogen balance) parameters. Plant height and physiological parameters were measured on the 7th, 14th, 21st, 28th and 35th days from the beginning of the treatment. The results obtained in this paper indicate the specificity of the plant genotype-microorganism relationship. The influence of the applied treatments on the morpho-physiological parameters varied specifically depending on the genotype as well as on the considered measurement period. In the Gružanski zlatni genotype, the applied treatments caused a significant increase in the values of most of the examined parameters in relation to the control, which makes it superior to the Narvik genotype. Therefore, further research will focus on the interactions between plant growth promoter bacteria and the GZ genotype, with a focus on beneficial effects that these bacteria have on the plant.

AB  - In this study we have investigated the effect of T. harzianum on growth, content of chlorophyll and epidermal flavonols and metal distribution in tomato plants. Trichoderma strain, isolated from the A horizon (5–30 cm) of agricultural soil used in organic production, was applied near the root in the sixth leaf development phase of tomato. Tomato plants were grown in a growth cabinet up to the stage of 10 leaves. Content of chlorophyll (Chl), epidermal flavonols (Flav) and antocyanins (Ant) were measured in vivo non-destructively. The concentration of Cd, Co, Cu, Cr, Fe, Mn, Ni, Se, and Zn was measured in different parts of tomato plants by ICP-OES method. Results have shown that Trichoderma application positively affected growth of tomato plants, and significantly decreased nitrogen balance index. In Trichoderma treated plants the contents of Cr and Ni were significantly reduced in roots, while content of Cd tended to decrease in all plant parts, significantly in roots. Presented results indicate that investigated isolate is worthwhile testing for plant growth promotion in field conditions, taking in account different supply of macro and micronutrients.

AB  - Metal pollution of soils is important environmental risk, that impases the need for development
of different methods for their removal, The use of plants that are able to accumulate and tolerate high metal
concentrations is one approach that is being examined for that purpose. Sunflower (Helianthus annus 1.)
bas been proven as good byperacumulator of metals, with ability to extract them from the soil and translocate
thems from roots to shoots and leaves.
In this work we have examined ability of sunflower to accumulate copper in hydroponic conditions.
Sunlower plants were grown in presence of copper with final concentrations of 50 ppen, 100 pprr and 200
pp. Fresh and dry mass of different plant organs was measured, as well as plant height, 7 days after metal
application. ICP-OES method was used to measure concentration of copper in stem and leaves of sunflower
plants according to EPA 6010C method.
Results has shown that copper addition decreased plants height, fresh and dry mass of stem and leaves.
According to the heavy metal consent measured in different plant organs if can be suggested that
copper was translocated from stem fo leaves. In order to conclude that sunflower corld be wsed as good metal
accumulator in copper polluted soils, further analysis of copper content in roots should be undertaken.

AB  - An aerobic denitrifier was newly isolated and identified by VITEK (R) 2 Compact System and MALDI-TOF MS as P. stutzeri strain D1. Sequence amplification indicates that the denitrification genes napA, nirS, norB and nosZ are present in a novel strain D1, as well as in reference strain ATCC 17588. Strain D1 had capability to fully remove 3 g/L of nitrate (as KNO3) in 48 h, while the reference strain completed this task in 60 h. Single factor experiments indicate that the optimal conditions for biomass production were: temperature of 30 degrees C, pH value of 7 and inoculum volume of 5 vol. %. Scaling up of biomass production of both denitrifiers was successfully performed in 3 and 7 L laboratory bioreactors by reaching 9 log CFU/mL of the viable cells. The results demonstrate the feasibility of using investigated P. stutzeri strains in denitrification processes and the simplicity of the up-scaling of biomass production for the treatment of large areas contaminated with nitrate.

AB  - Trichoderma koningiopsis and T. gamsii belong to clade Viride of Trichoderma, the largest and most diverse group of this genus. They produce a wide range of bioactive secondary metabolites, including peptaibols with antibacterial, antifungal, and antiviral properties. The unusual amino acid residues of peptaibols, i.e., alpha-aminoisobutyric acid (Aib), isovaline (Iva), and the C-terminal 1,2-amino alcohol make them unique among peptides. In this study, the peptaibiomes of T. koningiopsis and T. gamsii were investigated by HPLC-ESI-MS. The examined strains appeared to produce 19-residue peptaibols, most of which are unknown from literature, but their amino acid sequences are similar to those of trikoningins, tricholongins, trichostrigocins, trichorzianins, and trichorzins. A new group of peptaibols detected in T. koningiopsis are described here under the name "Koningiopsin". Trikoningin KA V, the closest peptaibol compound to the peptaibols produced by these two strains, was selected for structural investigation by short MD simulation, which revealed that many residues show high preference for left handed helix formation. The bioactivity of the peptaibol mixtures produced by T. koningiopsis and T. gamsii was tested on agar plates against bacteria, yeasts, and filamentous fungi. The results revealed characteristic differences in bioactivities towards the different groups of target microorganisms, which can be explained with the differences in their cell wall structures.
