AB  - Soil pH is one of the most important limiting factors for crop cultivation, including maize. About 30-40% of the world's arable land is acidic, and over a billion ha is alkaline. Today, there are 205 million ha of arable land under maize in the world, so it ranks third in area after rice and wheat. Maize hybrids have wide genetic variability and high pH tolerance. We tested the tolerance of maize hybrids seedlings of ZP 4708 and ZP 5797 to pH 5, 6, 7, and 8. Results showed that hybrid ZP 4708 has a higher adaptability to low and high pH, due to the higher value of germination energy (GE), shoot length (ShL), shoot fresh weight (ShFW), shoot dry weight (ShDW), germination rate index (GRI), and seedling vigor index (SVI) than hybrid ZP 5797. Results further showed, on average for hybrids, that pH 5 and pH 8 significantly decreased the GE, root length (RL), ShL, root fresh weight (RFW), ShFW, root dry weight (RDW), shoot fresh weight (ShDW), and SVI. These parameters did not differ significantly between pH 6 and pH 7. Seed germination was not affected by the pH, indicating that the seed vigor of both hybrids supports full germination potential. However, it could be expected that exposure to the lowest and highest pH values of the medium could affect seedlings growth in the field conditions, even though germination is high. SVI showed a positive and significant correlation with all investigated parameters, except germination (G) and relative seedling water content (RSWC).

AB  - Maize is the top-produced crop in the world. Its chemical composition makes it suitable for human consumption, animal feed, and industrial uses. The total world production of maize in 2021 was 1210 billion tonnes from cultivating about 205 million ha. However, there are many limiting factors for cultivation, such as soil pH. Acidic soils are present on 30%–40% of the world's arable land, while more than 1 billion hectares are alkaline soils. It is important to choose genotypes of crops tolerant to high or low pH. Therefore, we conducted research in laboratory conditions on the influence of pH values (5, 6, 7, and 8) on seed germination and seedling growth of two maize Serbian hybrids ZP 4708 and ZP 5797. The hybrid ZP 4708 had higher germination energy (GE), shoot length (ShL), shoot fresh weight (ShFW), shoot dry weight (ShDW), germination rate index (GRI), and seedling vigor index (SVI) than hybrid ZP 5797. GE, root length (RL), ShL, root fresh weight (RFW), ShFW, root dry weight (RDW), ShDW, and SVI have the highest values in treatment with optimal pH 7, and lowest in treatment pH 5. However, these parameters did not
differ significantly between the treatments pH 6 and pH 7.

AB  - The objective of this study was to evaluate the effect of applying lactic acid bacteria (LAB) and 
enzymes mixture inoculants (Sil-All and Silaprilis) on the chemical composition and 
fermentation of high-moisture grain silage of two maize hybrids Zenit and ZP 735. Maize 
hybrids were harvested at 68-72% of dry matter. Commercial inoculants were prepared and 
sprayed following the manufacturer's specifications. Silages were stored in glass jars with a 
special valve filled with water in the middle of the lid. Significant differences between hybrids 
were found for ash, crude protein, pH, and acetic acid. The hybrid Zenit had significantly higher 
ash (14.9 g kg-1
dry matter (DM)), pH (4.03), and acetic acid (6.3 g kg-1 DM), and significantly 
lower crude protein (89.0 g kg-1 DM) than hybrid ZP 735 (12.5 g kg-1 DM, 3.98, 5.1 g kg-1 DM 
and 101.2 g kg-1 DM, respectively). Compared to control, LAB+enzymes mixture inoculants 
stimulated ensiling of high-moisture maize grain. Inoculants decreased the contents of ammonia 
nitrogen and acetic acid, and pH value, and increased the contents of dry matter, ash, crude 
protein, crude fat, and lactic acid during silage fermentation than control. Accordingly, the 
application of LAB+enzymes mixture inoculants is justified and they can be recommended for 
high-quality silage production in feeding livestock.

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

AB  - Managing N, P and K inputs in semi-natural meadow production systems is important for achieving maximum yields in livestock farming. The objective of the present study was to estimate the effect of different NPK levels (N0P0K0, N50P50K50, N100P50K50, N100P100K100, N150P100K100 and N200P150K150 kg ha-1 yr-1) on the yield, quality and nitrogen nutrition index (NNI) in a grassland community of Agrostietum capillaris (semi-natural meadow) in western Serbia. The study was conducted during the seasons of 2005-2008. The values of the investigated parameters, except for the unit N uptake, were the highest in 2004/2005 due to favorable climate conditions. The levels of nitrogen significantly increased all of the studied parameters compared to the control treatment, except for unit N uptake. Mineral fertilizers at N200P150K150 provided the highest green forage yield (25.12 t ha-1), dry matter yield (8.12 t ha-1), crude protein yield (876.3 kg ha-1), nitrogen uptake (140.2 kg ha-1) and nitrogen nutrition index (70.2%), and the lowest unit N uptake (0.0022 kg N kg DMY-1). The use of mineral fertilizers increased green forage yield, dry matter yield and crude protein yield, increasing fertilizer from lowest to highest rate increased fresh and dry matter yield, as well as protein yield. Based on the results of the study, monitoring of nutrition indices would be necessary in order to increase productivity and economic benefits.

Studija je sprovedena tokom perioda 2005-2008. Vrednosti ispitivanih parametara, izuzev usvajanja azota po jedinici mase, bile su najviše u 2004/2005 zbog povoljnih klimatskih uslova. Nivoi azota su značajno povećali sve ispitivane parametre u poređenju sa kontrolnim tretmanom, osim usvajanja azota po jedinici mase. Đubrenje sa N200P150K150 obezbedilo je najveći prinos zelene krme (25.12 t ha-1), prinos suve materije (8.12 t ha-1), prinos sirovih proteina (876.3 kg ha-1), usvajanje azota (140,2 kg ha-1) i indeks ishrane azotom (70,2%), kao i najmanji unos azota (0,0022 kg N kg PSM-1). Upotreba mineralnih đubriva povećala je prinos zelene krme, prinos suve materije i prinos sirovih proteina, povećavanjem đubriva od najmanje do najveće količine je povećalo prinos sveže i suve mase, kao i prinos proteina. Na osnovu rezultata studije, praćenje indeksa ishrane azotom bi bilo neophodna mera u cilju porasta produktivnosti i ekonomske efikasnosti.

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

AB  - Forage grass-legume mixture are highly productive ambience of
different plant species intended for animal nutrition. The competitiveness of
species in the mixtures is one of the important traits that significantly affect
grassland management. The goal of the study was to evaluate nitrogen nutrition
index of pure lucerne and their mixtures with grasses and sainfoin subjected to four
different levels of nitrogen in three years duration. The experiment had a
randomised block design with four replicates and eight treatments. Examined
treatments were pure lucerne crop and mixtures of lucerne, orchard grass, tall
fescue and sainfoin in the same proportion and four nitrogen fertilization rates (0,
70, 140, 210 kg ha-1). Pure lucerne achieved higher yield by 12.8% than their
mixtures. Forage production was the highest at 210 kgN ha-1 which was 14.6%
more than treatments without nitrogen. Nitrogen uptake by the plant that were
fertilized with N was significantly higher than the plants that were not fertilized. In
all three experimental years control nitrogen treatment had satisfactory value of
nitrogen nutrition index while other N treatments showed luxury consumption. Soil
N reserves and nitrogen fixation in the treatment where N was not applied, were
sufficient to ensure enough biomass production.

AB  - The aim of this research was to determine the production properties of red clover cultivated in monoculture and in mixtures with perennial ryegrass during two years with application of fertilizer in different rates of N. The experimental factors were two mixtures of perennial ryegrass and red clover arranged in different proportions of 70:30 (30CP), 50:50 (50CP) and monoculture of red clover (100CP). N was applied as ammonium nitrate (34% N) in three different levels: 0, 50 and 100 kg N ha-1. After each cut, the botanical composition was studied, the herbage production parameters and crude protein content were analysed. The share of red clover in the crop had a significant effect on all of the studied properties except for the leaf : stem ratio and leaf surface. Higher proportion of red clover increased yield, plant height, specific leaf area (SLA) and leaf area index (LAI). The height of red clover plants and LAI were higher in monoculture than in mixtures by 12% and 46%, respectively. The crude protein content was higher in mixtures than in pure crop by 8%.  N fertilization reduced the yield of red clover, and increased other production parameters as well as the crude protein content.

AB  - Soil salinity is one of the most important factors limiting crop
productivity. It is known that the agricultural soils with high concentrations of salts
increase day by day. For this reason, it is imperative to monitor the tolerance of
crops and genotypes to salt stress because they have different threshold sensitivity.
Generally, higher salinity levels in the media negatively affect the germination of
seeds and seedling growth of most crops. Germination, germination speed and
seedling growth parameters significantly decrease with increasing salt
concentrations in the media. Soil salinity adversely affects germination, resulting in
poor plant stand. Therefore, the development of salt tolerant genotypes of crops
with promising yields would be an ideal solution for growing plants on these soils,
as well as sustainable food and feed production.
AB  - Zaslanjivanje zemljišta je jedan od najvažnijih faktora koji ograničava produktivnost useva. Poznato je da površina poljoprivrednog zemljišta sa visokom koncentracijom soli raste iz dana u dan. Iz tog razloga, neophodno je pratiti toleranciju useva i genotipova na stres soli jer imaju različitu graničnu osetljivost. Generalno, viši nivoi saliniteta u medijuma negativno utiču na klijavost semena i rast klijanaca većine useva. Klijavost, brzina klijanja i rast klijanaca značajno se
smanjuju sa povećanjem koncentracije soli u medijumu. U suštini, salinitet i kiselost negativno utiču na klijanje, što dovodi do lošeg (proređenog) sklopa. Stoga bi razvoj genotipova tolerantnih na soli sa obećavajućim prinosima bilo idealno rešenje za gajenje biljaka na takvim zemljištima, kao i za održivu proizvodnju hrane.

as well as sustainable food and feed production., Zaslanjivanje zemljišta je jedan od najvažnijih faktora koji ograničava produktivnost useva. Poznato je da površina poljoprivrednog zemljišta sa visokom koncentracijom soli raste iz dana u dan. Iz tog razloga, neophodno je pratiti toleranciju useva i genotipova na stres soli jer imaju različitu graničnu osetljivost. Generalno, viši nivoi saliniteta u medijuma negativno utiču na klijavost semena i rast klijanaca većine useva. Klijavost, brzina klijanja i rast klijanaca značajno se
smanjuju sa povećanjem koncentracije soli u medijumu. U suštini, salinitet i kiselost negativno utiču na klijanje, što dovodi do lošeg (proređenog) sklopa. Stoga bi razvoj genotipova tolerantnih na soli sa obećavajućim prinosima bilo idealno rešenje za gajenje biljaka na takvim zemljištima, kao i za održivu proizvodnju hrane.",

AB  - Vojvodina Province is a major alfalfa producer in Serbia with approximately 35.7% of total area and total production share of approximately 43.1%. In this paper, the data on area, production and yield of alfalfa observations from 1947 to 2018 and their variation and trends are analysed. The data indicate wide differences in the harvested area, total production and yield of alfalfa. The analysis of data indicates that harvested area and total production of alfalfa have declined over the past decades. Yield trend shows strong yield increase during 1950-1980 followed by periods of declined growth rates to 1990. After 1990s, dry matter yield has been stagnant. However, the increase, decrease and stagnation in yield are not strictly linear.

AB  - During an experiment conducted in Serbia, near the city of Šabac over two growing seasons (2012/13 and 2013/14), the yield and quality of grassland treated with an organo-mineral fertilizer (farmyard manure 30 t ha-1 +10 wt.% zeolite) was monitored and compared to fertilization with pure manure (30 t ha-1), spring nitrogen application (50 kg/ha N), treatment with pure zeolite, and treatment without the addition of fertilizers. All fertilizers were spread in the autumn of 2012. Nitrogen was exceptionally applied in the spring of 2013 and 2014. Dry matter (DM) yield and forage quality were evaluated during the growing season, in two forage harvests. In addition to yields, the chemical composition of the biomass, concentrations of total protein fractions and in vitro DM digestibility were examined in detail. The biomass yields of both cuts in the first season were considerably higher after the application of manure with zeolite, pure manure and mineral nitrogen, compared to the control and zeolite. No significant differences among the treatments were noted with regard to the chemical composition of the biomass, or the effect of the type of fertilization on DM digestibility of the biomass from the natural grassland. The application of the organo-mineral fertilizer considerably reduced the share of NPN in total protein, compared to pure manure.

AB  - Monoculture and intensive use of mechanization and inorganic chemicals are leading to degradation and erosion of our soils and agro-ecosystems. At the same time, the production of animal feeds that are rich in protein is constantly decreasing in many European countries. Modest cultivation needs, favorable content of nutrients, and beneficial effect on the environment, make field pea and oat mixtures promising crops to tackle these issues. In three growing seasons and without irrigation or fertilisation, we have examined two basic field pea cultivars (Kosmaj, OS Adam) and one leafless cultivar (OS Letin) intercropped with oat (NS Jadar), with seeding rates, field pea: oat – 100:10%; 100:20%. Results have shown that basic type cultivars have better overall development and higher yields compared to leafless cultivar, whether grown as single crops or in the mixture. Basic cultivars (OS Adam, Kosmaj) achieved higher protein content, compared to cultivar Letin, 163.9 g kg-1, 153.3 g kg-1, 136 g kg-1, respectively. Yields were higher in 100:20% mixtures, compared to 100:10% mixtures and single grown crops, and we conclude that intercropping these species is superior to cultivating them separately. Protein content wasn’t significantly different between two seeding rates, thus seed rates shouldn’t be lower than 100:20%.

AB  - In seed crops of many temperate grass species stem lodging occurs during reproductive development. Nitrogen (N) spring application maximizes grass seed production, but influence the incidence and severity of lodging. Therefore, we analyzed the effect of different N rates (0, 50 and 100 kg ha−1) in spring and growth regulator trinexapac-ethyl (TE) doses (0, 0.5 l ha−1 and 1 l ha−1; Moddus 250-EC) on morphological parameters of two commercial Italian ryegrass (Lolium multiflorum Lam) cultivars, K-13 diploid and K-29 tetraploid type. Before swathing, internodes length, stem length, spike length and the number of spikelet from 10 randomly picked tillers per plot were measured. The increase of N rate significantly increased the fifth and sixth internodes length of cv. K-29. Also, significant decrease of internodes length was achieved in cv. K-29 with 1 l ha−1 TE, while stem length in cv. K-13 was unchanged by TE and N spring application. Cv. 29 had higher spike length than cv. K-13 and TE decreases length in both cultivars, in K-13 with 1 l ha−1 TE, while in K-29 with both doses of TE. The use of higher N fertilizer rates together with TE in Italian ryegrass seed crop can be more valuable practice for tetraploid cultivars.

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

As a species that is most commonly used on grasslands, it is grown in mixtures with other types of grasses and legumes. The objective of the research was to investigate the performance of perennial ryegrass at various proportions in the mixtures with red clover and lucerne, and how different levels of N fertilization affect its competitiveness. Ryegrass achieved the highest yield with lucerne at seeding rate 50:50 and with red clover at seeding rate 70:30. Relative grass yield (RYg) of mixtures ranged from 1.01 to 1.55 respectively, which means that ryegrass in mixtures achieved 0.1-55% greater yield than pure ryegrass crop. N fertilization increased DMY and RYg, leaf : steam ratio, specific leaf area (SLA), leaf area ratio (LAR) and leaf area index (LAI) in both years thus increasing the competitive capability of perennial ryegrass.
AB  - Višegodišnji ljulj je veoma važna i rasprostranjena vrsta trava koja se koristi za ishranu stoke, naročito preživara. Kao vrsta koja se najčešće koristi na travnjacima, ona se uzgaja u mešavinama sa drugim vrstama trava i mahunarki. Cilj istraživanja bio je istražiti proizvodne rezultate višegodišnjeg ljulja u različitim proporcijama u smešama sa crvenom detelinom i lucerkom, kao i kako različiti nivoi N đubrenja utiču na njegovu konkurentnost. Ljulj je postigao najveći prinos sa lucerkom pri razmerisetvenoj of 50:50 i sa crvenom detelinom, 70:30. Relativni prinos trava (RYg) smeša se kretao od 1,01 do 1,55, što znači da je ljulj u smešama postigao 0.1-55% veći prinos od čistog useva. N đubrenje povećalo je DMY i RYIg, odnos lista i stabljike, specifičnu lisnu površinu (SLA), odnos lisnih površina (LAR) i indeks lisnih površina (LAI) u obe godine, čime se povećava konkurentna sposobnost višegodišnjeg ljulja.

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

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

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

AB  - During grass seed production, a large amount of low forage quality biomass has been produced. Tall growing perennial grasses such as tall fescue (Festuca arundinacea L.) and Italian ryegrass (Lolium multiflorum Lam.) can be used as an alternative source for bioenergy production as they can be grown in less cultivated areas, their residues in seed production could be valuable energy source and can be potentially used as a dual purpose crop (bioenergy and forage). In this research, potentials of yearly biomass production of two important forage grasses grown for seed (Italian ryegrass and tall fescue) varying modes of sowing and nitrogen fertilisation were shown. As a byproduct, postharvest residues of Italian ryegrass reached to 8.8 t/ha in the Mačva region in favourable weather conditions, during 4-year production, while tall fescue reached in southern Banat 10.6 t/ha in the first and 15.1 t/ha in the second year of production.
AB  - Pri proizvodnji semena trava se stvara velika količina biomase koja je slabijeg kvaliteta za ishranu domaćih životinja, ali može biti pogodna za korišćenje kao izvor energije biljnog porekla. Na primeru gajenja dve travne vrste, italijanskog ljulja tokom 4 godine (2003-2006) i visokog vijuka tokom 2 godine (2014-2015) za seme, kroz različite mere agrotehnike (varirajuće načine setve i đubrenja azotom) su prikazani potencijali godišnje produkcije biomase. U skladu sa zemljištem i osobinama trava su primenjeni sledeći međuredni razmaci: 20, 40 i 60 cm za italijanski ljulj i 15, 30, 45 i 60 cm za visoki vijuk, setvene norme od 5, 10, 15 i 20 kg/ha za obe vrste i prolećna prihrana sa 0 i 75 kg/ha N visokog vijuka i 0, 50, 100 i 150 kg/ha kod italijanskog ljulja. Italijanski ljulj je tokom 4 godine ispitivanja na području Mačve imao maksimalni prinos od 8,8 t/ha iz dva otkosa, u prvoj godini proizvodnje semena, pri povoljnim meteorološkim uslovima. Visoki vijuk je u prvoj godini proizvodnje semena u uslovima južnog Banata ostvario maksimalno 10,6 t/ha iz dva otkosa, pri najvećem međurednom rastojanju gajenja (60 cm), kao i 15,1 t/ha u drugoj godini na istom međurednom rastojanju. Prinosi biomase trava ostvareni uz skromnu agrotehniku, u sklopu proizvodnje semena trava, ukazuju na značajan potencijal za proizvodnju bioenergije.

U skladu sa zemljištem i osobinama trava su primenjeni sledeći međuredni razmaci: 20, 40 i 60 cm za italijanski ljulj i 15, 30, 45 i 60 cm za visoki vijuk, setvene norme od 5, 10, 15 i 20 kg/ha za obe vrste i prolećna prihrana sa 0 i 75 kg/ha N visokog vijuka i 0, 50, 100 i 150 kg/ha kod italijanskog ljulja. Italijanski ljulj je tokom 4 godine ispitivanja na području Mačve imao maksimalni prinos od 8,8 t/ha iz dva otkosa, u prvoj godini proizvodnje semena, pri povoljnim meteorološkim uslovima. Visoki vijuk je u prvoj godini proizvodnje semena u uslovima južnog Banata ostvario maksimalno 10,6 t/ha iz dva otkosa, pri najvećem međurednom rastojanju gajenja (60 cm), kao i 15,1 t/ha u drugoj godini na istom međurednom rastojanju. Prinosi biomase trava ostvareni uz skromnu agrotehniku, u sklopu proizvodnje semena trava, ukazuju na značajan potencijal za proizvodnju bioenergije.",

AB  - The aim of this investigation was to estimate the effects of crop density on the plant height (PH), stem diameter (SD), number of leaves per plant (NL), forage yield hectare-1 (FY), dry matter yield hectare-1 (DMY), stem percentage (SP), leaf percentage (LP) and ear percentage (EP) in two maize hybrids of FAO maturity group 600 (ZP 684 and NS 6010). Field trials were carried out in rainfed farming in the Srem region (location Putinci: 44° 59' 19' North and 19° 58' 11' East) during years 2007 and 2008. Three crop densities were compared: G1 - 51,020 plants ha-1, G2 - 59,524 plants ha-1 and G3 - 71,429 plants ha-1 (corresponding to spacing of 70 × 28, 70 × 24, and 70 × 20 cm). Plots were organized as completely randomized block system design in four replications. PH (265.45 cm), SD (2.40 cm), FY (68.63 t ha-1) and DMY (24.63 t ha-1) were significantly higher in 2007 than in 2008 (261.78 cm, 2.32 cm, 61.17 t ha-1 and 21.04 t ha-1, respectively). Hybrid NS 6010 had significantly higher PH (266.23 cm), SD (2.39 cm) and NL (14.75) than hybrid ZP 684 (261.0 cm, 2.33 cm and 13.99, respectively). Increasing crop density significantly increased the PH, FY, DMY and SP, and significantly decreases the SD and EP. Therefore, crop density of 71,429 plants ha-1 (70 x 20 cm) can be recommended for growing hybrids of FAO 600 maturity group in climatic conditions of Srem in order to achieve high yields of forage and dry matter.
AB  - Cilj ovog istraživanja bio je da se ispita uticaj gustine useva na visinu biljke (VB), prečnik stabla (PS), broj listova po biljci (BL), prinos krme po hektaru (PK), prinos suve materije po hektaru (PSM), udeo stabla (US), udeo lista (UL) i udeo klipa (UK) dva hibrida kukuruza FAO 600 grupe zrenja (ZP 684 and NS 6010). Ogledi su izvedeni u suvom ratarenju u regionu Srema (lokacija Putinci 45° 00' SGŠ, 19° 58' IGD) tokom 2007. i 2008. godine. Upoređivane su tri gustine biljaka: G1 - 51,020 biljaka ha-1, G2 - 5,9524 biljaka ha-1 i G3 - 71,429 biljaka ha- 1 (odgovara razmaku 70 × 28, 70 × 24 i 70 × 20 cm). Ogledi su postavljeni po slučajnom blok sistemu u četiri ponavljanja. VB (265.45 cm), PS (2.40 cm), PK (68.63 t ha-1) i PSM (24.63 t ha-1) bili su značajno veći u 2007. godini nego u 2008. (261.78 cm, 2.32 cm, 61.17 t ha-1 and 21.04 t ha-1). Hibrid NS 6010 imao je značajno veću VB (266.23 cm), PS (2.39 cm) i BL (14.75) nego hibrid ZP 684 (261.0 cm, 2.33 cm and 13.99). Povećanje gustine biljaka značajno je povećalo VB, PK, PSM i US, i značajno smanjilo PS i UK. Gustina biljaka 71,429 biljaka ha-1 (70 x 20 cm) može se preporučiti za gajenje hibrida FAO 600 grupe zrenja u klimatskim uslovima Srema u cilju postizanja visokih prinosa krme i suve materije.

AB  - The aim of this investigation was to estimate the effects of foliar fertilization on quantitative traits (plant height, first pod height, number of nodes per plant, number of pods per plant, number of grain per plant, grain yield per plant, 1000-grain weight and grain yield) in two soybean cultivars (Balkan and Bečejka). Studied cultivars belong to different maturity groups (Balkan - I and Bečejka - 0). Four treatments of fertilization were tested: control (no fertilization), Urea (46 kg N ha-1), Urea (46 kg N ha-1) + Wuxal super (5 l ha-1) and Urea (46 kg N ha-1) + Ferticare I (5 kg ha-1). Wuxal super and Ferticare I were foliar applied two times at the R2-R3 growth stage. The field experiments were carried out in dry land farming in the region of Vojvodina province at location Putinci (45° 00' N Lat., 19° 58' E Long.), during the years 2007 and 2008. In both research years, Balkan had higher values for all investigated traits than Bečejka. Results showed that foliar fertilizers significantly increased the values for all quantitative traits. Ferticare I is more effective than Wuxal super in soybean because this fertilizer has higher concentration of macronutrients. Foliar fertilization of soybean reduced the negative impact of small amounts of rainfall during the summer months on grain yield.
AB  - Cilj istraživanja je bio da se oceni efekat folijarne ishrane na kvantitativne osobine (visina biljke, visine prve mahune, broj nodusa po biljci, broj mahuna po biljci, broj zrna po biljci, prinos zrna po biljci, masa 1000 zrna i prinos zrna) dve sorte soje (Balkan i Bečejka). Ispitivane sorte pripadaju različitim grupama zrenja (Balkan - I, Bečejka - 0). Upoređivane su četiri tretmana ishrane biljaka: kontrola, Urea (46 kg N ha-1), Urea (46 kg N ha-1) + Wuxal super (5 l ha-1) i Urea (100 kg ha- 1) + Ferticare I (5 kg ha-1). Wuxal super i Ferticare I primenjeni su folijarno u R2- R3 fazi rastenja i razvića soje. Ogledi su izvedeni u suvom ratarenju u Vojvodini na lokaciji Putinci (45° 00' SGŠ, 19° 58' IGD) tokom 2007. i 2008. godine. U obe godine istraživanja sorta Balkan je imala veće vrednosti za sve ispitivane osobine nego Bečejka. Rezultati su pokazali da je folijarna ishrana značajno povećala vrednosti svih ispitivanih kvantitativnih osobina. Viši prinosi postignuti su primenom Ferticare I nego primenom Wuxal super jer sadrži veću koncentraciju makroelemenata. Folijarno prihranjivanje soje umanjilo je negativan uticaj malih količina padavina tokom letnjih meseci na prinos zrna.

AB  - Managing N inputs in wheat production systems is an important issue in order to achieve maximum profitable production, and minimum negative environmental impact. The aim of this investigation carried out in dry land farming in the Vojvodina province (Serbia) was to estimate the effects of different N fertilization levels (0, 75, and 150 kg N ha(-1)) on some quantitative traits, rain-use efficiency (RUE), N agronomic efficiency (NAE), and N use efficiency (NUE) in two Serbian winter wheat (Triticum aestivum L.) cultivars 'Pobeda' and 'Renesansa'. 'Pobeda' had higher grain yield (4437 kg ha(-1)) and RUE (8.32 kg ha(-1) mm(-1)) than 'Renesansa' (4265 kg ha(-1) and 8 kg ha(-1) mm(-1), respectively). Grain yield (4652 kg ha(-1)) and NUE (31.46 kg kg(-1) N) were higher in the 2010-2011 season (favorable weather conditions) than in the 2011-2012 (4050 kg ha(-1) and 27.59 kg kg(-1) N, respectively). The highly significant effect on grain yield (4396 and 4494 kg ha(-1)), RUE (8.24 and 8.45 kg ha(-1) mm(-1)), NAE (3.11 and 2.21 kg kg(-1) N) and NUE (58.62 and 29.96 kg kg(-1) N) had levels of 75 and 150 kg N ha(-1). NAE and NUE declined at high N rates. Based on the results of this study, farmers should be advised that the use of large amounts of N increases production costs and reduce the economic benefits. The increase in wheat production is possible by selecting adapted genotypes with improved NUE.

AB  - Soybean is main source of vegetable protein and oil in the world. Soybean used for livestock feed, human food and industrial processing. Soybean is main raw material for the preparation of a protein feed for all types and categories domestic animals. In the world the largest part of soybean produced, about 70% is used to feed livestock. In Serbia the area under soybeans and grain yield varies from 144386 ha to 170255 ha and 1.73 t ha-1 and 3.18 t ha-1 , respectively. Grain yield depends on the amount of rainfall from late June to early September when the highest needs for water (since beginning of flowering until the end of grain filling). Soybean is most sensitive to drought stress during the pod formation and grain filling stages.

AB  - The study of five forage grasses (Lolium multiflorum, Festuca rubra, Festuca arundinacea, Arrhenatherum elatius and Dactylis glomerata) was conducted on an uncontaminated cultivated land, of leached chernozem type, and on 'Nikola Tesla A' (TENT A) thermal power station ash deposit. The concentrations of: As, Pb, Cd, Zn, Ni, Fe and Cu in grasses grown on two media were compared. Grass samples have been collected in tillering stage, when they were in full development. The aboveground biomass was cut in three replications during the vegetative period at about 3-5 cm height, imitating mowing and grazing. The concentrations of As and Ni were elevated in media samples collected from TENT A ash deposit, while the level of all studied elements in soil samples collected from cultivated land were within allowed limits. The variance of certain elements amounts in plant material collected from TENT A ash deposit was less homogeneous; the concentrations of As, Fe and Ni were higher in grasses collected from ash deposit, but Pb and Cu concentrations were higher in grasses grown on cultivated land. The concentrations of Zn were approximately the same in plants collected from the sites, whereas Cd concentrations were slightly increased in grasses grown on the ash deposit. In general, it can be concluded from the results of this study that the concentrations of heavy metals in plants collected from both sites do not exceed maximal tolerant levels for fodder. The use of grasses grown on ash deposit for forage production should be taken with reserve.
AB  - Pet krmnih trava, ježevica (Dactylis glomerata L.), francuski ljulj (Arrhenatherum elatius Presl.), italijanski ljulj (Lolium multiflorum Lam.), crveni vijuk (Festuca rubra L.) i visoki vijuk (Festuca arundinacea Schreb.) su ispitivane na nezagađenom njivskom zemljištu na oglednom dobru 'Radmilovac' u Beogradu, i na odlagalištu pepela termoelektrane 'Nikola Tesla A' (TENT A) u Obrenovcu. Merene su koncentracije As, Pb, Cd, Zn, Ni, Fe i Cu u zemljištu i pepelu, kao i u tkivima ispitivanih vrsta trava u cilju utvrđivanja zdravstvene bezbednosti u ishrani domaćih životinja. Uzorci trava su prikupljani u fazi klasanja, u punom vegetativnom razvoju. Skidana je nadzemna biomasa u 3 ponavljanja na visini od 3-5 cm, oponašajući ispašu ili kosidbu. Analiza je pokazala visok sadržaj As i Ni u pepelu dok je sadržaj svih elemenata u zemljištu bio u dozvoljenim koncentracijama. Koncentracije As, Cd, Fe i Ni su bile više u travama sa pepelišta, koncentracije Pb i Cu u travama sa njivskog zemljišta, dok su koncentracije Zn bile slične u uzorcima sa oba lokaliteta. Rezultati ispitivanja ukazuju da krma trava sa obe lokacije ne akumulira metale iznad tolerantnog nivoa za ishranu goveda, ali da se mora oprezno pristupiti mogućnosti korišćenja trava sa pepelišta za krmu.
