AB  - The mineralization of nitrogen in apple orchard soil will increase the soil supply. An incubation study to test the soil potential and the validity of analytical methods was conducted at 3, 8, 15, and 20 °C for up to 128 days on soils from western and south-eastern Norway. Soils with the highest pH showed the highest mineralization. The mineralization increased with increasing temperature and time, but start-up N reduced mineralization. The mineralization cannot be estimated from standard soil chemical parameters because the different C/N ratio indicates organic material of different origin and quality. The increase in NO3-N started very quickly and ranged from 17 to 182% and 12 to 64% after 8 days at 3 °C and 20 °C, respectively. There was no correlation between total N in the soil and the amount of mineralized N. On average, the mineralization increased by 5–7% for a change of 1 °C in the interval from 8 to 15 °C in the soil. The chemical extraction method using heated KCl correlated well with the mineralization data. On average, the chemical method estimated 30 kg N ha−1, which corresponded to 0.48% of total N. Recommendations for N fertilization based on total N in the soil overestimate the contribution of plant-available N in most cases.

AB  - Natural grasslands and pastures occupy 5.96% of the country territory. According to European Space Agency, changes in land cover from 2000–2015 indicate decrease in total grassland area of 1765 km2 (30.03%), emphasizing dominant conversion of grasslands to forests. Ongoing depopulation trend, rural to urban migrations, and decrease in livestock population are some of main factors impacting grasslands. This trend favors further naturalization of pastures striving to increase the areas under natural grasslands. Such conversion will contribute to overall change in biodiversity richness, especially in areas with saline soils and high mountain regions with increased level of endemic species. Grasslands play important role in overall sustainability, but their importance it is not properly addressed. Environmental experts should recognize drivers of grasslands degradation and propose appropriate conservation and restoration measures. The priority should be avoidance of grassland degradation that requires good assessment of their current conditions and monitoring of plant, soil, climate conditions and land use activities. Further measures are deduced to sustainable land management practices and smooth human interventions, whereas the aftermost adopted measures should be related to restoration. Grasslands should have more emphasized role in our society and LDN principles should be applied for their preservation.

AB  - Over the last two decades, Serbian agriculture has suffered increased losses and damages due to the more frequent occurrence of the extreme weather events caused by the climate change. The most significant losses are recorded in years with droughts and high summer temperature (such as 2012 and 2017). Significant losses in orchards are caused by the frost in late winter or early spring, when the flowering occurs early, due to a prolonged period of unusually high temperatures. On the other hand, damages caused by low winter temperatures are decreasing.

In order to assess the risk levels brought by the climate change and extreme weather events to the agricultural plant production in different regions of the country, analyzed are frequency of the occurrence of the weather events that may have significant negative effect to the yields of the most important crops (corn, maize, sunflower, soybeans) and fruits (plum, peach, raspberry, apple, wine grape), as well as pastures and meadows. Vulnerability is assessed through the analysis of agricultural production structure in the administrative districts of Serbia.

Weather events with potentially negative effect to yields and most vulnerable phenophases are defined for each crop or fruit considered in the analysis. For each plant and each potentially dangerous weather event one or more bioclimatic indices were adopted and calculated for the past, present and future. For the present (2000-2019), daily data on temperature and precipitation were used from the eOBS gridded observations dataset. Results of 8 regional climate models from the EURO-CORDEX initiative were combined into an ensemble. The ensemble was constructed upon the evaluation of their ability to simulate past climate characteristics over the country. The chosen simulations are done under the RCP8.5 IPCC greenhouse gasses emission scenario, for the periods 1986-2005, 2021-2040, 2041-2060 and 2081-2100.

Results showed that projected frequencies of the events such are water deficit and/or droughts and high temperatures in the critical phenophases of the considered plants, and late spring frost, are increasing in the future. The median value of the frequency of those weather events projected for the next 20 years is mostly already reached. Therefore, more weight is given to the 75th percentile of the ensemble projections for the increasing risks and the 25th percentile for the decreasing risks, as upper and lower limits of the most probable range of the future climate changes.

This assessment is used for drafting the National Climate Change Adaptation Plan in order to propose and prioritize adaptation measures for the agricultural sector in the Republic of Serbia, on the national and administrative districts level.

AB  - INTRODUCTION and AIMS: Climate changes, with their consequent increase in temperature and precipitation, have a significant impact on the soil surface. Soil temperature is very important for plant development and it
depends on humidity (soil water content), air temperature and canopy cover (Fischer et al., 2021). Canopy temperature is one of the most important physiological parameters related to transpiration, leaf water potential and stomatal conductance. Plant water status is frequently monitored using thermal remote sensing devices (Martínez et
al., 2016; Santesteban et al., 2017; Zhang et al., 2018b; Zhang et al., 2018c). Bearing in mind the mentioned
significance, the aim of this research is to analyse the effect of irrigation regime on soil temperature, soil moisture and temperature of grapevine and grass cover.
MATERIALS and METHODS: The research was conducted in the vineyard of the white wine grape variety (cv. Panonia) in Plavinci near Belgrade (44° 41’ N; 20° 41’ E; 176 m.a.s.l.) from April to September 2021. The experiment was arranged using a block design with three replications. The intra-row spacing of plants (vines) amounted to 0.9 m, while the inter-row spacing was 1.8 m (1.62 vines m-2). The vineyard was minimally tilled. The space between rows was covered by a grass-legume mixture which is the subject of this study, as well. Climate data were obtained from the meteorological station located in the vineyard. Water, physical and chemical properties of soil were determined by the standard field and laboratory analyses. Irrigation was performed using the drip irrigation method. Three irrigation regimes were established: 1) full irrigation (F), when 100% of crop evapotranspiration (ЕТс) was ensured; 2) deficit irrigation (D), 50% of ЕТс ensured and 3) drought (S), the rainfed
treatment. In all treatments soil moisture (by the vines and on the grass cover) was monitored using a gravimetric method each 7 to 10 days and continuously using TDR probes. Soil temperature probes were also used for measuring the soil temperature (soil by the vines). Temperature of the canopy cover (grapevine and grass) was measured 10 times during the vegetation (from mid-Jun to mid-September) using FLIR T335 thermal imaging camera. Three photographs were taken during each temperature measurement in all applied treatments. The photographs were later analysed using the sample of 10 temperatures per photo (30 samples per treatment) with FLIR Tools software. RESULTS and CONCLUSIONS: Soil moisture measured by means of gravimetric and TDR method was the highest in the F treatment and the lowest in the S treatment. Soil moisture content mostly remained within the soil water depletion limits during the research period. Soil temperature was the highest in the deficit irrigation treatment (it was not monitored in the control treatment). It varied from 5°С to 32.5°С and amounted to the average of 20°С from March to September. The average temperature of the grapevine canopy varied from 24.1°С in the F treatment, 25.2°С in the D treatment and 26.0°С in the S treatment. Temperature of the grapevine canopy was lower than the air temperature in all treatments, which indicates that plants were not exposed to water stress. The average temperature of grass cover in the inter-row space which was not directly irrigated varied from 38.3°С in the D treatment to 40.6 °С in the S treatment. It was mainly higher than the air temperature, which indicates that the grassland was exposed to water stress. The obtained results clearly highlight the significant impact of irrigation regime on both soil moisture and temperature and canopy cover temperature of grapevine and grass cover. In addition, grapevine tolerance to water deficit can concluded.

AB  - Extreme weather and climate events over the past years have been bringing damage and
losses to agricultural production in Serbia.
As a part of the development of the National climate change adaptation plan, weather and
climate events and extremes that may significantly influence the growth of agricultural plant,
their quality and yields, were defined as a first step in the climate change risk assessment
within the agriculture sector. Such events included: high summer temperature, low winter
temperature, spring frost, drought, intense precipitation, floods, hail and storms, but also
slow-onset changes such as inter annual redistribution of precipitation and rising air
temperatures. Based on the selected potentially dangerous phenomena, bioclimatic indices
were formulated for various fruit species, grapevine, strategically important field crops,
meadows and pastures.
The degree of exposure to selected weather and climate events was assessed for the past,
present and future, based on the analysis of daily data on temperature and precipitation from
the eOBS gridded observations dataset (2000-2019) and projections of 8 regional climate
models under the RCP8.5 greenhouse gases emission scenario, for the periods 1986-2005,
2021-2040, 2041-2060, 2081-2100. The vulnerability assessment was done for the
administrative districts and the entire territory of the Republic of Serbia based on the
valuation of the severity of socio-economic consequences that considered events might have.
The risk assessment was done combining the estimated levels of exposure and vulnerability.

AB  - Due to the air temperature increase, longer growing seasons and erratic rainfalls in the last two decades, natural grasslands like meadows or pastures grow in unfavourable climatic conditions that disable the regeneration. The aim of this work is to assess the impact of climate changes on the water requirement of grasslands in Serbia. The results of ensembles of nine regional climate models from the EURO-CORDEX database were used to analyse future climatic conditions. As the most probable value, the median of scores obtained for each ensemble member was considered. The period of 1986–2005 was used as the reference. The time slices in future periods are: 2016–2035 (the near future), 2046–2065 (the mid-century) and 2081–2100 (the end of the century). Analyses were conducted for two scenarios of GHG emissions: RCP4.5 and RCP8.5. Permanent grasslands will be more prone to drought risks in the future. Water shortage could be expected at the end of May when the water stored in the soil will be depleted by the duration of drought until September heavy rains. According to both scenarios, an increment of water requirement of 7% could be expected in the near future. The RCP4.5 scenario projects an increase in the water requirement in the range of 10.7–24.2% from the mid to the end of the century. The less favourable but more realistic RCP8.5 scenario projects a water need increment in the range from 4% to 14 % in the mid-century and 28.4–41.9% toward the end of the century. Recent research indicates that drought resistance will be developed through natural diversity and the spread of species resistant to high temperatures and water scarcity.

AB  - In limited growing conditions, intercropped field peas and oats can represent a significant source of forage rich in protein. If applied correctly, factors such as nitrogen fertilizer, the mowing phase, and sowing norms can significantly increase the productivity of these mixtures. Field trials were conducted to examine their productivity under different nitrogen levels (0, 40, 80 kg ha−1 ), different sowing norms/mixtures (field peas: oats—100:15%; 100:30%), and two stages of growth (full flowering, full pod formation). Nitrogen fertilizer and different sowing norms had a significant effect on the biomass, hay, and crude protein yields. On average, the highest hay yields were achieved with 80 kg ha−1 N (4.96 t ha−1 ), followed by 40 kg ha−1 N (4.27 t ha−1 ). The highest protein yields were achieved with 40 kg ha−1 N (CP—704.1 kg ha−1 ), followed by 80 kg ha−1 N (CP—637.6 kg ha−1 ). Sowing norm 100:30% achieved higher hay yields: 100:30%—4.82 t ha−1; 100:15%—4.44 t ha−1, while 100:15% achieved higher crude protein yields: 100:15%—730.4 kg ha−1; 100:30%—692.7 kg ha−1 on average. The costs were not significantly increased with the nitrogen fertilizer, but the net profits were increased by as much as 163%, depending on the nitrogen level and the mixture. Nitrogen fertilizer also achieves higher economic efficiency for the mixture 100:15% compared to the 100:30% mixture. Mixtures of field peas and oats outperform single-grown crops and provide cost-effective feed for a short time. Using optimal seed ratios and nitrogen fertilizer can significantly increase the productivity and profitability of the feed with minimal impact on the overall production costs.

AB  - The influence of sowing method, growth regulator and harvest method on alfalfa seed yield was examined in three years (2015-2017), in locality near Belgrade, with using alfalfa variety NS Banat ZMS II. Research showed the statistically very significant effect of sowing method on seed yield, and the best average way for all three years period was 60 cm between rows of sowed seed. The growth regulator proved to be effective only in the rainy year, while harvesting crops previously treated with desiccant proved to beuseful, with the exception in the year of establishment when this difference was not statistically significant. Meteorological conditions had the highest influence on the seed yield, amount of precipitation in the vegetation period mostly, and the researched factors have proved to be useful in suppressing the consequences of poor weather. In years suitable for seed production, the recommendation for the production practice is an intermediate distance of 60 cm and the use of a desiccant.

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  - This study examined the in vitro crude protein (CP) degradability of wilted, dried for hay and ensiled Medicago sativa, Trifolium pratense and Sorghum sudanense, as well as of ensiled legume-sudan grass mixtures. The rumen degradable protein (RDP) was estimated using the latest Cornell net carbohydrate and protein system (CNCPS v6.5) and with the Streptomyces griseus protease assay (48 h of incubation). Sudan grass forages were the lowest in moderately degradable CP and the highest in CP fraction C, while red clover showed the least values for the soluble true protein like alfalfa forages for slowly degradable protein bound in neutral detergent fibre (NDF). Ensiling of legume-sudan grass mixtures decreases N-NH3 content by 12.2 and 5.1% in comparison with alfalfa and red clover silages, respectively. The RDP values for sudan grass (fresh, wilted, hay) were lower by 7.2 to 7.9% or 10.4 to 15.7% (CNCPS or S. griseus procedure) and up to 0.8 or 5.3 to 9.7% in comparison with alfalfa and red clover, respectively. The reduction of protein degradability in ensiled legume-sudan grass mixtures was 5.5 or 6.1% and 1.5 or 3% compared to alfalfa and red clover silages, respectively. Due to higher rumen undegradable protein content, the sudan grass and legume-sudan grass mixtures may be efficiently used to improve the protein utilization in ruminant nutrition.

AB  - A field trial with four red clover cultivars ('K-39', 'K-17', 'Una' and 'Viola') was conducted on a leached vertisol acid in reaction (pHH2O 4.8) to assess the effect of foliar treatment with phosphorus and potassium on seed yield and seed yield components. A single foliar application of phosphorus and potassium (P52K34) was made at the intensive growth stage during the second growth in the second year of cultivation. Seed yield and seed yield components were analyzed from the second growth in the second year of the experiment. Foliar treatment with phosphorus and potassium had a significant positive effect on seed yield and yield components in some red clover cultivars in some years. The most positive effect was recorded in 'K-17' and 'Viola'. The different effects of foliar-applied mineral fertilizers on the tested cultivars were the result of their phenotypic differences. Foliar treatment gave the best performance in 2011, when the climatic conditions were the most favorable for red clover growth and development. In general, the seed yield of red clover cultivars increased by 105 kg ha-1 under foliar fertilization. The positive effect of the foliar treatment with phosphorus and potassium was attributed to the need for these elements in many plant processes. The results showed that the foliar application of mineral fertilizers in red clover seed production on acid soils can be an acceptable practice under conditions favoring high yields.

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  - 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.

AB  - The aim of the present investigation was to assess the influence of rhizome mass on the success of plantation establishment and biomass yield of the bioenergy crop M. × giganteus during 10 years of cultivation. The experiment included three treatments with different rhizome masses: 10-20 g (very low); 25-35 g (low), and 40-60 g (medium mass). Planting density was 2 rhizomes m-2. The plants were harvested by mowing of the whole above-ground biomass each year in February. Out of the total number of planted rhizomes, the lowest emergence was noticed in very low mass rhizomes. In the first season, the greatest number of stems and crop height were encountered under the treatment with the highest rhizome mass. In the second season, crop heights were almost equal in all treatments. During the first two seasons, the highest biomass yields were recorded under the treatments with the highest rhizome masses. Although the analyzed parameters were highest with the rhizomes of 40-60g during the crop establishing stage, starting from the third season of cultivation, high yields of above-ground biomass may be obtained also with lower mass rhizomes. Having the highest biomass yield (25.85±7.36 Mg DM ha-1), the crop established with rhizomes of 25-35 g clearly stood out.

abstract = "The aim of the present investigation was to assess the influence of rhizome mass on the success of plantation establishment and biomass yield of the bioenergy crop M. × giganteus during 10 years of cultivation. The experiment included three treatments with different rhizome masses: 10-20 g (very low); 25-35 g (low), and 40-60 g (medium mass). Planting density was 2 rhizomes m-2. The plants were harvested by mowing of the whole above-ground biomass each year in February. Out of the total number of planted rhizomes, the lowest emergence was noticed in very low mass rhizomes. In the first season, the greatest number of stems and crop height were encountered under the treatment with the highest rhizome mass. In the second season, crop heights were almost equal in all treatments. During the first two seasons, the highest biomass yields were recorded under the treatments with the highest rhizome masses. Although the analyzed parameters were highest with the rhizomes of 40-60g during the crop establishing stage, starting from the third season of cultivation, high yields of above-ground biomass may be obtained also with lower mass rhizomes.

AB  - A cutting experiment was conducted to analyze the changes in the crude protein (CP) fraction content and in the estimated ruminal protein degradability of forage, obtained in conditions of simulated rotational spring grazing on permanent grassland. The field trial was conducted on permanent pasture during 2015 and included three cuttings as a simulated rotational spring grazing. For determination of protein degradability of pasture forage, the fractionation of the CP according to Cornell Net Carbohydrate and Protein System (CNCPS v6.5) and the Streptomyces griseus protease assay were used. Relative to CP, no significant differences were found among cuts for ammonia N content (A1 fraction) and for protein fraction C which is completely unavailable to the animals. Values for soluble true protein (A2 fraction) and cell wall-associated protein, which is acid detergent soluble (B2), were significantly increased (p lt 0.05) while a significant reduction (p lt 0.05) of the moderately degradable protein (B1) content was determined during the growing season. The lower rumen degradable protein (RDP) content of grassland herbage was obtained in the second cut which was significant (p lt 0.05) according to the CNCPS procedure. Obtained high solubility and degradability of CP in pasture require adequate content of readily available carbohydrates in rations for grazing ruminants to provide efficient utilization of consumed protein.

AB  - BACKGROUND: /Aim. KIT (KIT proto-oncogene receptor tyrosine kinase) and PDGFRA (platelet-derived growth factor receptor alpha) gene mutations represent major molecular forces inside the gastrointestinal stromal tumors (GIST). Aim of this study was to evaluate these mutations in the patients who underwent surgical resection of gastric GIST, but without imatinib mesylate treatment. Methods. Retrospective clinical study included patients who were operated on due to gastric GIST from November 2000 till November 2016. A molecular analysis of paraffin embedded tumor tissue was performed, and the patients with the presence of KIT and PDGFRA mutations were further evaluated, with regard to the pathological tumor stage, disease recurrence and overall survival. Results. Out of 45 patients in total, 43 patients had KIT and PDGFRA mutations, and 2 patients were classified as the wild type GIST. After curative resection, 11 patients were classified as a low risk GIST, 8 as an intermediate risk and 26 as a high risk GIST. The KIT mutations were present in 37 patients, most commonly as deletion in exon 11. The PDGFRA mutations were present in 6 patients. The presence of KIT mutation had a strong statistical correlation with the mitotic index (p = 0.021). After the ten-year follow-up, all patients with the PDGFRA mutations were alive, while those with the KIT mutations had a survival rate of 71% (p = 0.31). Conclusion. The presence of KIT exon 11 deletion in the patients with primarily resected gastric GIST is associated with the higher mitotic index and worse overall survival than those present with the PDGFRA mutations. This results suggest prognostic significance towards more aggressive behaviors.

AB  - During an experiment conducted in Serbia, near the city of Sabac 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  - The aim of the research was to compare the productivity and quality of several forage grasses in the climate conditions of south-eastern Europe. The research was conducted during 2012 and 2013, in the south-western part of the Pannonian basin (vicinity of Osijek, Croatia). The experiment included 5 grass species: Italian ryegrass (Lolium multiflorum), cocksfoot (Dactylis glomerata), hybrid ryegrass (Lolium x boucheanum), perennial ryegrass (Lolium perenne) and timothy (Phleum pratense) cut three times per year, i.e. 6 cuttings in total for two years. The results have shown that there were significant statistical differences for all investigated traits between the years of the species and their interaction at the P lt 0.05 levels. In average, the highest dry matter yield was achieved during the first year of usage (10.4 and 9.1 t/ha). The average usage of two years, the highest yields of dry matter had Italian ryegrass and cocksfoot. Quality results showed that the cocksfoot was the least digestible because it contained over 700 g/kg of neutral detergent fiber (NDF) and 450 g/kg of acid detergent fiber (ADF), unlike the perennial ryegrass which had 559 and 327 g/kg of NDF and ADF. Energetically most productive was Italian ryegrass with a production potential of 19,739 liters of milk and with milk fat of 4%. On the protein productivity base, the most prominent was the cocksfoot which could produce 11,878 liters of milk from 713 kg proteins in one year. The results show that none of the tested grasses had a balanced relationship between protein and energy.

abstract = "The aim of the research was to compare the productivity and quality of several forage grasses in the climate conditions of south-eastern Europe. The research was conducted during 2012 and 2013, in the south-western part of the Pannonian basin (vicinity of Osijek, Croatia). The experiment included 5 grass species: Italian ryegrass (Lolium multiflorum), cocksfoot (Dactylis glomerata), hybrid ryegrass (Lolium x boucheanum), perennial ryegrass (Lolium perenne) and timothy (Phleum pratense) cut three times per year, i.e. 6 cuttings in total for two years. The results have shown that there were significant statistical differences for all investigated traits between the years of the species and their interaction at the P lt 0.05 levels. In average, the highest dry matter yield was achieved during the first year of usage (10.4 and 9.1 t/ha). The average usage of two years, the highest yields of dry matter had Italian ryegrass and cocksfoot. Quality results showed that the cocksfoot was the least digestible because it contained over 700 g/kg of neutral detergent fiber (NDF) and 450 g/kg of acid detergent fiber (ADF), unlike the perennial ryegrass which had 559 and 327 g/kg of NDF and ADF.

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  - 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  - A two-year study was conducted using seed of six cultivars of Trifolium pratense (red clover) and three cultivars of Lolium multiflorum (Italian iyegrass), to test the effect of different treatments including exposure to 50% H2SO4 for 10, 30, 60, 90 min; to 80 degrees C temperature for 10, 30, 60, 90 min; gibberellic acid (GA(3)) at 250, 500, 1000 and 1500 mg L-1; and potassium nitrate (KNO3) at 0.1, 0.2, 0.35 and 0.5%. Germination, dormancy and vigour of both red clover and ryegrass were assessed. In case of T. pratense seed, there was a significant (p  lt = 0.05 or p  lt = 0.01) interaction between all the cultivars and treatments. A significant (p  lt = 0.05) interaction was also observed between the L. multiflorum cultivars and H2SO4 including temperature treatments. However, no significant interactions were noted between the GA(3) or KNO3 treatment, germination and vigour. The results showed that by selecting the optimal treatment (H2SO4 30' or H2SO4 60'T. pretense and GA(3) 1000 mg L-1 L. multiflorum) for a particular cultivar it is possible to significantly improve germination and vigour, and thus ensure technologically more effective and economical establishment of a grass-legume mixture of L. multiflorum and T. pratense.

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.

AB  - The effects of three intra-row spacings (20, 24 and 28 cm) with inter-row spacing of 70 cm and seed inoculation with plant-growth-promoting bacteria (PGPB) [(Azotobacter chroococum, Azotobacter vineland, Bacillus megaterium and Bacillus licheniformis)] were investigated on stem diameter (SD), stem lodging (SL), percentage of barren plants (PBP), grain yield (GY) and rain-use efficiency (RUE) in maize hybrid Dijamant 6 in the province of Vojvodina, Northern Serbia in 2006, 2007 and 2008. The highest SD and GY and the lowest SL and PBP were recorded in favorable climatic conditions in 2006. The lowest RUE was recorded in 2008 (unfavorable climatic conditions). The lowest SD and RUE and the highest SL, PBP and GY were obtained at the smallest spacing between plants in a row (20 cm). Seed inoculation significantly increased SD, GY and RUE, and SL and PBP significantly decreased. Generally, in Northern Serbia and similar ecological regions, treatment using 20 cm intra-row spacing (plant density of 71429 plants ha(-1)) and seed inoculation could be recommended to improve stem lodging resistance, decrease the number of barren plants and increase grain yield. To reduce yield losses in high crop densities, farmers should adopt appropriate crop management practices such as inoculation of seed with bio-fertilizer.

abstract = "The effects of three intra-row spacings (20, 24 and 28 cm) with inter-row spacing of 70 cm and seed inoculation with plant-growth-promoting bacteria (PGPB) [(Azotobacter chroococum, Azotobacter vineland, Bacillus megaterium and Bacillus licheniformis)] were investigated on stem diameter (SD), stem lodging (SL), percentage of barren plants (PBP), grain yield (GY) and rain-use efficiency (RUE) in maize hybrid Dijamant 6 in the province of Vojvodina, Northern Serbia in 2006, 2007 and 2008. The highest SD and GY and the lowest SL and PBP were recorded in favorable climatic conditions in 2006. The lowest RUE was recorded in 2008 (unfavorable climatic conditions). The lowest SD and RUE and the highest SL, PBP and GY were obtained at the smallest spacing between plants in a row (20 cm). Seed inoculation significantly increased SD, GY and RUE, and SL and PBP significantly decreased. Generally, in Northern Serbia and similar ecological regions, treatment using 20 cm intra-row spacing (plant density of 71429 plants ha(-1)) and seed inoculation could be recommended to improve stem lodging resistance, decrease the number of barren plants and increase grain yield. To reduce yield losses in high crop densities, farmers should adopt appropriate crop management practices such as inoculation of seed with bio-fertilizer.",

AB  - Grass-legume mixtures represent complex communities of grasses and legumes that make better use of resources and have a number of positive traits in comparison to monoculture. The aim of our research was to examine competitive ability of perennial ryegrass in mixtures with lucerne and red clover (50/50, 70/30) in condition of fertilization with three different nitrogen levels (0, 50, 100 kg ha-1). Dry matter yield of perennial ryegrass in mixtures with red clover was higher compared to mixtures with lucerne. Nitrogen had a very significant impact on perennial ryegrass production. Added N significantly increase DM production of grass treatment with 100 kgN ha-1. The values, of relative yield above 1 (RY >1), aggressivity index and competitive balance index, above 0 (Ag > Cbg > 0) indicated higher competitive ability of perennial ryegrass in relation to legumes. Competitive ability of ryegrass was higher in 70/30 mixtures and mixtures with lucerne. N fertilization increases competitive ability of ryegrass and decreases competitive ability of legumes.
AB  - Travno-leguminozne smeše predstavljaju složene zajednice trava i leguminoza koje bolje koriste prirodne resurse i imaju niz pozitivnih osobina u odnosu na monokulturu. Cilj našeg istraživanja je bio da se ispita konkurentna sposobnost engleskog ljulja u smešama sa lucerkom i crvenom detelinom (50/50, 70/30) u uslovima đubrenja sa tri različita nivoa azota (0, 50, 100 kg ha-1). Prinos suve materije engleskog ljulja u smeši sa crvenom detelinom bio je veći u poređenju sa smešom sa lucerkom. Azot je imao značajan uticaj na prinos engleskog ljulja. Dodati azot je značajno povećao prinos engleskog ljulja, naročito doze od 100 kgN ha-1. Vrednosti relativnog prinosa iznad 1 (RI> 1), indeksa agresivnosti i indeksa konkurentske ravnoteže iznad 0 (Ag> Cbg> 0) ukazuju na veću konkurentsku sposobnost engleskog ljulja u odnosu na mahunarke. Кonkurentna sposobnost engleskog ljulja bila je veća kod 70/30 smeša i smeša sa lucerkom. N djubrenje povećava konkurentsku sposobnost ljulja i smanjuje konkurentsku sposobnost leguminoza.
