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 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.
AB  - Cilj našeg istraživanja je bio da procenimo uticaj mase rizoma bioenergetskog useva Miscanthus × giganteus na uspešnost zasnivanja i prinos biomase tokom prvih 10 godina gajenja.

Žetva košenjem celokupne nadzemne biomase izvođena je svake godine u februaru. Od ukupnog broja posađenih rizoma najslabije nicanje zabeleženo je kod rizoma najmanje mase. U prvoj godini gajenja najveći broj stabala i najveću visinu useva zabeležili smo u tretmanima sa najvećom masom rizoma. Međutim, u drugoj godini gajenja visina useva sva tri tretmana bila je približno ista. U prve dve godine gajenja najveću biomasu prinosa ustanovili smo u tretmanima sa najvećom masom rizoma. Iako su u fazi zasnivanja useva analizirani parametri bili najbolji sa rizomima mase 40-60 g, visoki prinosi nadzemne biomase od treće godine gajenja mogu se dobiti korišćenjem rizoma manjih masa. Jasno se ističe usev zasnovan sa rizomima mase 25-35 g sa najvećim prinosom biomase (25,85±7,36 Mg SM ha -1).

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  - 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  - A simple field trial was performed to investigate the influence of less successful miscanthus culture establishment due to scarce planting on the yield of aboveground biomass. The trial was carried out on highly productive soil of non-carbonate chernozem type. Two months old miscanthus sprouting rhizomes with 1-2 developed stems were planted. The experiment included three levels of planting density: 0.50, 0.65 and 1.00 sprouting rhizomes/m2. At the lowest planting density (0.50), the average yield of 4-8 years old plantation, which is the stage with the highest aboveground biomass yield, amounted to 13.5±2.9 t dry matter (d.m.)/ha, while at the planting density of 1.00, the achieved yield was 21.2±4.5 t d.m./ha. Our results show that, at the recommended planting density of 15000 rhizomes/ha, on a highly productive soil, even with low survival of planted seedlings (> 43 %), satisfying yields of aboveground miscanthus biomass may be obtained.

Poljski ogled je zasnovan na visoko-produktivnom zemljištu tipa izluženi černozem. Sađeni su busenovi miskantusa starosti 2 meseca, sa 1-2 razvijena stabla. Ogled je obuhvatio 3 gustine sadnje: 0,50; 0,65 i 1,00 busenova miskantusa po m2. Faza zasnivanja useva trajala je 3 godine. Pri najnižoj gustini sadnje (0,50) prosečan prinos useva od 4-8 godine gajenja, kada se dostižu maksimumi prinosa nadzemne biomase, iznosio je 13,5±2,9 tona suve materije (s.m.)/ha, naspram 21,2±4,5 tona s.m./ha pri gustini sadnje 1,00. Rezultatipokazaju da se kod preporučene gustine sadnje rizoma miskantusa od 15000 rizoma/ha, na visoko produktivnom zemljištu, u povoljnim agroekološkim uslovima i pri relativno niskom prijemu (>43%) mogu dobiti zadovoljavajući prinosi nadzemne biomase miskantusa.

Poljski ogled je zasnovan na visoko-produktivnom zemljištu tipa izluženi černozem. Sađeni su busenovi miskantusa starosti 2 meseca, sa 1-2 razvijena stabla. Ogled je obuhvatio 3 gustine sadnje: 0,50; 0,65 i 1,00 busenova miskantusa po m2. Faza zasnivanja useva trajala je 3 godine. Pri najnižoj gustini sadnje (0,50) prosečan prinos useva od 4-8 godine gajenja, kada se dostižu maksimumi prinosa nadzemne biomase, iznosio je 13,5±2,9 tona suve materije (s.m.)/ha, naspram 21,2±4,5 tona s.m./ha pri gustini sadnje 1,00. Rezultatipokazaju da se kod preporučene gustine sadnje rizoma miskantusa od 15000 rizoma/ha, na visoko produktivnom zemljištu, u povoljnim agroekološkim uslovima i pri relativno niskom prijemu (>43%) mogu dobiti zadovoljavajući prinosi nadzemne biomase miskantusa.",

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  - There are conflicting opinions about the need to fertilize Miscanthus and, also, the question has been raised whether Miscanthus should be irrigated, especially if water resources are limited. Crop growth modeling can help answer such questions. In this article the FAO AquaCrop water-driven model was selected to simulate Miscanthus biomass under different nutrient and water supply conditions. The article reports the outcomes of 6-year experiments with Miscanthus on two locations in Serbia: Zemun, where three fertilizer treatments were applied (N-l - 100kgha(-1), N-opt 50kgha(-1) and N-f nonfertilized), and Ralja, where only N-l 100kgha(-1) was applied. Model calibration focused on the measured data (root depth, crop phenology, and the above-ground biomass by year of growth. Calibration results showed a very good match between measured and simulated values. The largest and only significant difference was noted in 2008, when the crop was establishing and exhibited uneven radication. The simulation results for the next 5years showed a variance from -4 to 5.7%, believed to be a very good match. A high coefficient of determination (R-2=0.995) and high Willmott index of agreement (0.998) were also indicative of a good match between simulated and recorded biomass yields. The measured and simulated results for validated datasets at both locations were good. The average RMSE was 2.89 Mgha(-1); when compared to the deviations noted at the test site itself, it was apparent that they were smaller in all the years of research except the first year. The index of agreement was 0.97 and the coefficient of determination R-2 0.947. The AquaCrop model can be used with a high degree of reliability in strategic planning of Miscanthus cultivation in new areas, under different nutrient and water supply and local weather and soil conditions.

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  - Based on a greenhouse experiment, we evaluated nitrogen availability in the surface mineral layer of soil under various deciduous forest stands by analysing the following soil characteristics: total organic C, total N, initial content of easily available N inorganic forms, mineralized N content obtained by aerobic and anaerobic incubations and A-value. The experiment was performed on a test plant and through the application of urea enriched with 5.4% 15N. The studied forest soils are characterized by high mineralization intensity and high N availability indices. Aerobic incubation appears to be the most appropriate method for evaluating the available N content. The amounts of mineralized and nitrified N, obtained by aerobic incubation, with subtraction of the initial content of available mineral N forms are in correlation (P ≤ 0.05) with total organic C content (r = 0.916) and total soil N (r = 0.903) while the correlation with the C/N ratio is poor (r = 0.645).
