AB  - The content of daidzein, genistein, formononetin, and biochanin A isoflavones was studied in natural populations of red and Hungarian clover, to estimate their impact on fodder quality and to determine directions in possible breeding programs. The study included 6 red clover (Trifolium pratense) and 6 Hungarian clover (Trifolium pannonicum) populations, collected in the central Balkans. The differences between the species and among the populations were analysed. The average content of total isoflavones was 1.393 mg g–1 and 0.487 mg g–1 of air dry matter in Hungarian clover, respectively. While the most prevailed isoflavone in red clover was biochanin A (46%), the Hungarian clover populations were rich in genistein (43%). The red clover leaves accumulated the highest content of isoflavones. The Hungarian clover flowers and leaves had an equal amount of isoflavones. The obtained values of the total isoflavones could not affect the overall nutrient quality and therefore, researched natural populations of two clover species could be considered for further breeding programs.

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 znaĉajno povećali sve ispitivane parametre u poreĊenju sa kontrolnim tretmanom, osim usvajanja azota po jedinici mase.

AB  - Due to historical BACKGROUND:  of vegetation development, geographical position, climate and relief, Serbia represents one of the 158 world biodiversity centres, based upon the number of plant species and territory size (biodiversity index 0.72). Large areas in Serbia are under natural grasslands and pastures, composed of forage grass species, and important as source of natural plant genetic diversity and germplasm for breeding. These eco-systems represent basic prerequisites for sustainable forage production, but very low potential of them is utilized and genetic resources are not protected. Family Poaceae is present in Serbia flora with 70 genera and among them from the aspect of forage production and quality, the most important are perennial Festuca, Lolium, Dactylis, Phleum, Bromus, Arrhenatherum, Poa and Agrostis species. Most of these grasses have been bred in Serbia and lot of cultivars were released. These cultivars contain autochthonous Serbian material and represent great and important resource of genetic variability. Therefore, collecting of new samples which are acclimatised to local eco-geographical conditions and including them in plant ex situ gene bank is of exceptional importance for further utilization in different plant breeding programmes as well as genetic resources protection. These autochthonous populations have natural variability and very often have satisfactory yielding performance in comparison with introduced cultivars, which referred them for direct phenotypic selection for cultivars release. Broadening of forage grasses genotypes collection is permanent objective of Serbian scientists. Collected accessions are being characterized and evaluated for important phenological, morphological and agronomical traits. In this paper genetic resources of forage grass species, their diversity and potentials, state of the grasses gene banks, as well as possibility for breeding of new cultivars has been analysed.
AB  - Zahvaljujući svojoj geografskoj poziciji, klimi i reljefu, Srbija po broju biljnih vrsta i veličini teritorije (indeks biodiverziteta 0,72), predstavlja jedan od 158 svetskih centara biodiverziteta. Prirodne livade i pašnjaci zauzimaju značajne površine u Srbiji, veoma su bogate krmnim travnim vrstama i predstavljaju važan izvor germplazme za proces oplemenjivanja. Ovi ekosistemi predstavljaju osnovu za održivu stočarsku proizvodnju, pa iako se relativno male površine intenzivno koriste, javlja se potreba za očuvanjem postojećih, izuzetno bogatih, genetičkih resursa. Familija Poaceae je zastupljena u flori Srbije sa 70 rodova, a među njima, sa aspekta proizvodnje kvalitetne stočne hrane, najvažnije su vrste rodova Festuca, Lolium, Dactylis, Phleum, Bromus, Arrhenatherum, Poa i Agrostis. Veliki broj vrsta navedenih rodova je uključen u proces oplemenjivanja, a početni material za brojne registrovane sorte su bile uglavnom autohtone populacije, koje se odlikuju visokom varijabilnošću za mnoge osobine. Prikupljanje novih uzoraka, koji su tolerantni na lokalne eko-geografske uslove i njihovo uključivanje u biljnu banku gena, je od velikog značaja za dalje iskorišćavanje u različitim oplemenjivačkim programima, pa je stalno proširenje postojeće kolekcije krmnih trava permanentna aktivnost oplemenjivača u Srbiji. Prirodne populacije imaju visoku varijabilnost i veoma često zadovoljavajuće komponente prinosa u odnosu na postojeće sorte, što ih nakon karakterizacije i evaluacije važnih fenoloških, morfoloških i agronomskih osobina, preporučuje za direktno uključivanje u process selekcije. U ovom radu su predstavljeni genetički resursi krmnih trava, njihova divergentnost i potencijal, stanje u banci gena, kao i mogućnost kreiranja novih sorti.

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.

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., 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.",

AB  - In this study grape pomace was ensilaged without and with the addition of NPN substances (Benural) at the dose of 0.5, 1.0 and 1.5% of the amount of husk and with the addition of inoculant based on homo and hetero fermentative lactic acid bacteria. The greatest effect on the nutritional value had application of Benural, especially in increasing the CP content from 126.9 to 178.3 g kg-1DM, an increase of over 40%. Application of Benural increased the ammonia and soluble nitrogen several times, but even with the maximum addition of Benural percentage of ammonia nitrogen in the total nitrogen reached only slightly above 5% NH3 -N/Σ N (5.38%), while the percentage of soluble nitrogen in total nitrogen was 28.29%. The application of inoculants generally had no significant impact, both on the chemical composition and the fermentation process.

AB  - Serbia is a country with great potential and capacities for agriculture. Agriculture is the basis of Serbian economy and it is the backbone of the development of the country. It is the only sector with positive foreign trade balance, representing 21 % of total export. More than 17.3 % of the Serbian population live on farms and their basic income originates equally from crop and animal production. Cattle products constitute 42.6 % of overall animal production. In the last 10 years, the number of farms engaged in raising cattle, as well as the number of dairy cows, has declined. This reduction of approximately 2-3 % annually has resulted in stagnation and reduction of meat and milk production. Arable fields and gardens account for ca. 65 % of all agricultural land in Serbia, and of that 455,000 ha are fodder crops. The total area sown with alfalfa has experienced a slight reduction in recent years to the current level of 183 thousand hectares. Red clover is cultivated on 120 thousand hectares, while fodder corn fields are expanding. Since approximately two thirds of the Serbian territory consists of hilly or mountainous areas, natural grasslands cover about 1.45 million hectares, or almost 29 % of the total agricultural land area. Fodder crop production in Serbia is traditionally based on domestic cultivars and hybrid maize seeds. Since extensive forage production is dominating in Serbia, particularly in the upland regions, domestic breeding programs are essentially focused on genotypes that can survive and produce under the local agro-ecological conditions. This has led to the inclusion of several new objectives in the breeding programmes, with the aim to improve plasticity and resilience to environmental limitations. The main objectives are drought tolerance, root characteristics, field persistence linked to low pH tolerance and symbiotic N-fixation, tolerance to the most important pathogens, Fusarium sp., Coletotrichum sp. and Puccinia sp., and adaptability to different environmental extremes. The forage crop species currently in use in Serbia consist of highly productive cultivars, with improved dry matter quality. These cultivars can achieve and sustain a satisfactory level of plasticity under a wide range of climatic conditions, not only in Serbia but also on the Balkan Peninsula. Future steps to improve fodder crop production and husbandry in Serbia include regionalisation of forage production according to a set of recommendations, stabilisation of subsidy policies, consolidation of fields and farms, improvement of grassland management and production technologies, and creating a better and more efficient system of transfer of knowledge from scientists to farmers.

AB  - The aim of this paper was to evaluate the agronomic value of red clover (Trifolium pratense L.) wild populations. The analyzed material was gathered on the territory of Serbia and it was estimated which populations could be involved in the breeding program. 17 red clover populations were included in the research. Investigation was carried out at the experimental field of the Institute for forage crops, Krusevac, Serbia. The field trial was performed during three years (2008 - 2010) when data about morphological (green mass, dry mater, plant height, number of stems, number of lateral branches, number of internodes, length and width of a middle leaf lamina) and basic chemical parameters (quantity of crude proteins, crude fiber, ash, fat, NFE) were collected. In this paper, results of the research were processed by application of analysis of variance (ANOVA) and multivariation methods. Cluster analysis based on morphological traits resulted in formation of three clusters and the traits with the largest influence on grouping were: green mass, plant height, length and width of a leaf. Principal component method confirmed this separation and resulted in even more clear grouping of populations. Cluster analysis and PCA method were also applied to the traits of dry matter quality, when four clusters were formed, and the traits with the largest influence on grouping were percentages of protein, fat and fiber. Using both set of traits and several types of analyses contribute to grouping of populations which promise most and whose positive traits such as: high green mass yield, number of stems as well as the percentage of proteins can be combined for the purpose of getting synthetic varieties.

AB  - Tetraploid cultivars of Italian ryegrass have been developed and used as an alternative to diploid cultivars in an attempt to improve forage yield and quality. But, very often, production of tetraploid cultivars is reduced by unfavourable weather conditions. The objective of this research was to determine seed production stability of the tetraploid Italian ryegrass cultivar K29T in variable and contrasting environmental and meteorological conditions in Serbia. The study was conducted in four consecutive years and generations of seed multiplication. Every year, seed was harvested from the primary growth in the first production year after the year of establishment. Data of investigated traits (heading and harvest dates, tiller length, number of spikelets per spike, seed yield, dry herbage yield and 1,000 seed weight) were recorded for different management practices (stand densities and nitrogen applications). It was determined that seed yield, dry matter production and tiller length were presumably most affected by different environmental factors in different production years, and different management practice, especially different sowing densities. In contrast, number of spikelets per spike and 1,000 seed weight were less affected by management practice, except in the extremely arid 2003 year. Variation in seed yield was more related to variation in seed numbers than to variation in seed weight. In the first seed production year, the best density in this experiment was 15-20 kg ha−1 of seed sown at an interrow spacing of 60 cm without fertilizing or with only 50 kg ha−1 of N. Therefore, seed of tetraploid Italian ryegrass cv. K29T can be produced in diverse environmental conditions in Serbia, but lower stand densities allow for better plant tillering and the production of a greater volume of seed and, at the same time, good dry matter yield of the residual biomass.

AB  - The aim of this study was to examine genetic variability, heritability and correlation of seed yield components and seed yield of progenies of autochthonous populations and cultivars of perennial ryegrass, and that on the basis of these results distinguish genotypes that would be later used in the creation of new local cultivars of perennial ryegrass. Research was carried out on experimental fields and laboratories of the Agricultural Institute of Republic of Srpska in Banja Luka in 2007. and 2008., on 6 natural populations of perennial ryegrass collected in Bosnia and Herzegovina and two cultivars, Maja and Calibra as standard. Following parameters were analyzed: number of generative tillers per plant, time of flowering, spike length, number of spikelets per spike, seed yield per spike and plant and 1000 seed weight. Analysis of the results of the number of generative tillers per plant indicates a statistically significant difference in the studied populations and cultivars of perennial ryegrass. The highest average number of tillers per plant was found in the cultivar Maja (193.8), and the least number was detected in population Dragočaj (78.9), so statistical differences were highly significant. The longest period to beginning of flowering was determined in cultivar Calibra (56.5 days) and the shortest in population Laminci (43 days). The average length of spike of perennial ryegrass in the studied population was 22.78 cm and was significantly lower than cultivar Maja. Statistically significant differences between populations and variety Maja in the number of spikelets per spike were detected. The average seed yield per spike of studied populations was in level with cultivar Maja and 37.5% higher compared with variety Calibra.

abstract = "The aim of this study was to examine genetic variability, heritability and correlation of seed yield components and seed yield of progenies of autochthonous populations and cultivars of perennial ryegrass, and that on the basis of these results distinguish genotypes that would be later used in the creation of new local cultivars of perennial ryegrass. Research was carried out on experimental fields and laboratories of the Agricultural Institute of Republic of Srpska in Banja Luka in 2007. and 2008., on 6 natural populations of perennial ryegrass collected in Bosnia and Herzegovina and two cultivars, Maja and Calibra as standard. Following parameters were analyzed: number of generative tillers per plant, time of flowering, spike length, number of spikelets per spike, seed yield per spike and plant and 1000 seed weight. Analysis of the results of the number of generative tillers per plant indicates a statistically significant difference in the studied populations and cultivars of perennial ryegrass. The highest average number of tillers per plant was found in the cultivar Maja (193.8), and the least number was detected in population Dragočaj (78.9), so statistical differences were highly significant. The longest period to beginning of flowering was determined in cultivar Calibra (56.5 days) and the shortest in population Laminci (43 days). The average length of spike of perennial ryegrass in the studied population was 22.78 cm and was significantly lower than cultivar Maja. Statistically significant differences between populations and variety Maja in the number of spikelets per spike were detected. The average seed yield per spike of studied populations was in level with cultivar Maja and 37.5% higher compared with variety Calibra. In the studied populations of perennial ryegrass seed yield ranged from 5.21 g (Dragočaj population) to 15.40 g (Kupres population). Weight of 1000 seeds was highest in the variety Calibra (2.60 g) and lowest in population Maglajani (1.94 g).

AB  - This research studied the phenotypic correlation coefficients between three Sorghum species, namely forage sorghum S. bicolor Moench. (c. NS-Džin), Sudan grass S. sudanense L. (c. Zora) and interspecies hybrid S. bicolor x S. sudanense (c. Siloking). The analyses were performed on plant material samples taken from the first cutting, when plants were in the beginning phase of tasseling. The following morphologic traits were studied: plant height, number of leaves per plant, stem leaf weight and mean stem weight. Additionally, their direct and indirect effect on dependent variable green biomass yield was analyzed, for which path coefficients were calculated. This method enables more quality and full insight into relations existing among the studied traits, more precise establishment of cause-effect connections among them, as well as to separate direct from indirect effects of any particular trait on dependent variable, being biomass yield in this case. The analysis of phenotypic coefficients revealed differences in direct and indirect effect of certain traits on dependent variable. Sudan grass had the highest stem (2.281 m) and most leaves per plant (7.917). Forage sorghum had the largest leaf weight per plant (49.05 g), while interspecies hybrid had the highest mean stem weight (80.798 g). Variations of these morphologic traits among species were found to be significant and very significant. Morphologic traits - stem height and weight significantly affected sorghum green biomass yield. Leaf number and leaf portion in total biomass were negatively correlated with yield. Cultivars differed significantly regarding morphologic and productive traits. Sudan grass had the lowest green biomass yield, while forage sorghum and interspecies hybrid had significant yield increase.

AB  - Due to specific climatic conditions, perennial ryegrass breeding in Serbia is focused on resistance or tolerance to abiotic stress factors, especially to drought and high temperatures. These traits should be associated with high dry matter yield and quality. Therefore, most frequently used initial material is autochthonous populations and ecotypes adapted to local agro-ecological conditions, but knowledge about their variability of important traits for breeding is missing. Pre-selection evaluation of ten populations of perennial ryegrass originating from Serbia is presented in this paper. Twenty five traits were investigated during the two-year period and processed using analysis of variance and multivariate statistical methods (cluster and principal components analysis). The goal was to determine diversity and genetic distances of investigated populations by phenotyping and to define traits considerably affecting the variability and discrimination of populations. On cluster diagram two groups of population are observed, but geographic origin of populations (lowland, hilly, mountainous habitat) was not influence to clustering of collection. Factor analysis has clarified that first seven principal components (PC) described almost 95%. The traits which show high correlation coefficients with first principal component were plant height in first cut, leaf length and width, DM of generative tillers, spike and spikelet length and 1000 seed weight, and with second principal component time of heading, terminal internode length, DM of vegetative tillers, spikelet number and FSU. It can be concluded that variability between populations was high and that differences of population were mainly affected by most important traits for breeding, such as components of dry matter production and some seed yield components.

AB  - Italian ryegrass (Lolium multiflorum Lam.) cv. Tetraflorum sown with different inter-row spacings and seeding rates was grown under the agroecological conditions of Western Serbia. Field experiments were carried out between 2002 and 2006, and biometric characteristics-generative tillers, seed yield, and shoot dry mass-were measured during the first production year. Italian ryegrass was grown with 3 row spacings (20, 40, and 60 cm), using 4 seeding rates (5, 10, 15, and 20 kg ha(-1)). Tiller length was affected by stand density, while 2 other tiller parameters were affected considerably less by the treatments applied. The influence of tiller characteristics on yield components was insignificant. The highest seed yield in the first production year varied with treatment, depending on seasonal conditions. Plant parameters and seed yield were impacted by inter-row spacing, marked, however, by an opposite impact in and and humid weather conditions. Inter-row spacing of 40 cm was the least risky for seed production. While the increase in seed rates (15-20 kg ha(-1)) in stand establishment provided higher seed yields in years with unfavorable weather conditions, the seed rate had either no impact on seed yield, or decreased the seed yield as a result of ryegrass lodging, following seed shedding in the years with favorable weather conditions. Abundant shoot dry mass was obtained with some treatment variants, but there was no linear correlation between seed yield and yield components.

AB  - The dependence between traits is determined by the correlation coefficients. The experiment was conducted using two generations of honey bee. The first generation consisted of the mother queen bees, and the second were their offspring. The experiment lasted for two years per generation. In the first generation, the correlation between colony strength in the both spring and autumn inspection and the honey yield was high. Considering food supply, the high correlation between food supplies in autumn and honey yield was determined. In the offspring colonies, the high correlation was determined between colony strength in autumn and honey yield. The colony strength in the spring inspection and honey yield were in medium correlation. Also, the medium correlation was determined between honey yield and brood area in the spring inspection. Other studied characteristics in the offspring colonies were not significantly correlated with honey yield.

AB  - Three cultivars (domestic K-13 diploid and K-29 tetraploid, and introduced Tetraflorum tetraploid) were investigated in two years' trials, with and without spring Pi-fertilizing. The results of this investigation showed that the high quality of Italian ryegrass seed could be achieved with two cuttings in the first production year. Spring M-application did not influence TSW (thousand seed weight), germination rate and total germination. The produced seed from the first harvest cut was of an excellent quality, with high germination rate (K-13 - 79%, K-29 - 88% and Tetraflorum - 87%) and total germination (K-13 - 91%, K-29 - 96% and Tetraflorum - 93%). The difference in TSW was obtained between diploid and tetraploids (in the average 2,81 gr in proportion to 4,56 and 4,84 gr). The seed produced from the second harvest cut had lower germination and TSW.

AB  - The Italian ryegrass forage quality was investigated by means of crude protein and fibre content. The Italian ryegrass was produced at the first cut of the first production year. Interrow spacing did not have any statistical significance for protein and fibre content. The protein content decreased by increasing seeding rate from 5 to 20 kg ha-1, in average from 159,8 to 144,5 g kg-1, and increased by increasing amount of N fertilizer from control to 150 kg ha-1 in average 133 - 169 g kg"1. Fibre content did not have statistical significance, i.e. it had lower variation. There is a negative correlation between the protein and fibre content (P lt 0,05), but lower correspondence r= -0,23. Earlier cutting of Italian ryegrass had more important influence on fibre content, because when heading starts, crude fibre content is increased.

AB  - During two investigation years two trials with meadow fescue (Festuca pratensis Huds.), cultivar K21 and tall fescue (Festuca arundinacea Schreb.), cultivar K20 have been performed. Analysis of upper, intermediate and lower panicle branches from generative shots has showed their influence on determining of yield and quality of seed. Lower and intermediate panicle branches have showed higher importance in seed yield determining than upper branches in both species. Influence of panicle branches position on 1000 seed weight has been more variable in meadow fescue (CV(%)=8,41), while in tall fescue variability for germination energy and total germination have been larger (CV(%)=11,05 and 2,26 respectively).
AB  - Tokom dvogodišnjeg istraživanja (2006-2007) izvedeni su ogledi sa livadskim vijukom (Festuca pratensis Huds.), sorta K21, i visokim vijukom (Festuca arundinacea Schreb.), sorta K20. Uzimanjem gornjih, srednjih i donjih grana iz cvasti (metlice) generativnih stabljika utvrđen je njihov uticaj na formiranje prinosa i kvalitet semena. Kod obe ispitivane vrste donje i srednje grane iz cvasti su ispoljile daleko veći značaj u formiranju prinosa semena u odnosu na gornje grane. U pogledu kvaliteta semena, uticaj položaja grana na masu 1000 semena pokazao je veću varijabilnost kod livadskog vijuka, (CV(%) = 8,41), dok je visoki vijuk ispoljio veću varijabilnost za energiju klijanja semena i ukupnu klijavost (CV(%) = 11,05 i CV(%) = 2,26).

AB  - Modern procedures in animal husbandry are based on using preserved forages for ruminants during the year, which provides the most stable production and milk quality. From that point of view, biological additives based on homofermentative and heterofermentative lactic acid bacteria have grate importance, as well as cellulolitic preparations. Based on temporary additives by animal feed with small amount of fermentabile carbohydrates fermentation is intensifying and targeting, fibre is degradating and aerobe stability of silage is increasing. Thanks to such results we can see the series improves in milk and meet production. Lacking of residues and positive influences on animal health and quality of animal products are advantages of biological additives.
AB  - Savremeni trendovi u tehnologiji siliranja zasnivaju se na maksimalnoj kontroli proteolize, korišćenju hemijskih sredstava iz reda organskih kiselina i njihovih soli, upotrebi bioloških dodataka i povećanju aerobne stabilnosti silaža. Korišćenje hemijskih konzervanasa zadnjih godina je minimalno u Evropi, dok je u Americi u potpunosti isključeno. Danas su širom sveta najaktuelniji mikrobiološki dodaci na bazi raznih sojeva homofermentativnih bakterija, koje intenziviraju i usmeravaju fermentaciju uz maksimalno racionalnu potrošnju fermentabilnih ugljenih hidrata. Ova vrsta dodataka je važna pre svega za silaže od leguminoza, koje se odlikuju nedovoljnom količinom šećera i visokim pufernim kapacitetom. Pored bakterija biološki dodaci mogu sadržati i celulolitičke enzime, čime se povećava iskoristivost tako tretiranih silaža, kao i njihov kvalitet. Najnovija generacija mikrobioloških dodataka sadrži i heterofermentativne bakterije mlečne kiseline čiji proizvodi fermentacije šećera povećavaju aerobnu stabilnost kukuruzne silaže.
