Item A rapid and cost-effective procedure for delineation and utilization of genomic microsatellites for paralleled genotyping in Vicia faba(Czech Academy of Agricultural Sciences, 2015-03-31) Aleksic, Jelena M; Banović Đeri, Bojana; MILJUŠ-ĐUKIĆ Jovanka; JOVANOVIĆ Živko; Mikić, Aleksandar; Ćupina, Branko; ZLATKOVIĆ Bojan; Andjelković, Snežana; Spanu, Ilaria; Jelić, Mihailo; MAKSIMOVIĆ VesnaItem Autochthonous plant growth-promoting rhizobacteria enhance Thymus vulgaris growth in well-watered and drought-stressed conditions(Lithuanian Research Centre for Agriculture and Forestry, 2021-12-06) Stamenov, Dragana; Djuric, Simonida; Hajnal Jafari, Timea; Andjelković, SnežanaItem Effect of Nitrogen Fertiliser and Lime on the Floristic Composition, Soil Microbes and Dry Matter Yield of Danthonietum calycinae Grassland(University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, 2019-11-08) Zornic, Vladimir; Stevović, Vladeta; Lugić, Zoran; Andjelković, Snežana; Jevtić, Goran; Radović, Jasmina; Petrović, MirjanaNatural grasslands are significant resources for forage production, which is not exploited enough, mostly because of low production, as a result of bad grasslands management. The research has been carried out on the association Danthonietum calycinae to evaluate the effects of different nitrogen application rates (N20, N80 and N140) and lime (1 tha-1) on the floristic composition, soil microbes and dry matter yield. Botanic composition was strongly influenced by the treatments, especially by N applications. Nitrogen fertilisation led to significant increase of grass species in the association (from 57% to 82%), while higher rate of nitrogen caused a significant decrease of plants from other families (especially legumes). Application of low and medium rate of nitrogen positively effect on microbial abundant in soil, but the highest dose (140 kg N) reduced all microbial count, except fungi. Mineral nitrogen fertilisation had a favourable effect on dry matter yield in all treatments. The highest increase in dry matter yield relative to the control was in N140 treatments (6.66 t ha-1). Results indicated that optimal applications of nutrients for this association is application of PK and lime and 80 kg of nitrogen which enable high yield (6.38 t ha-1) in comparison with control (3.16 t ha-1) and preserving soil fertility and the environment at the same time.Item Forage Cultivation Under Challenging Environment(Springer Nature Singapore, 2023) Milenković, Jasmina; Petrović, Mirjana; Andjelković, Snežana; Mitra, DebasisWe already experience the effects of climate change, and future agricultural output will face a number of challenges. High temperatures, scarcity of water, rising pollution, an increase in weeds and pests are just a few of the negative effects it may have. The area and quality of arable land are both decreasing as a result of climate change. It will not be able to generate adequate feed for animals since the negative effects of climate change will reduce the output of fodder plants. Reduced human food production is the eventual result. Every stage of plant growth is impacted by environmental factors (planting, seed germination, early vegetative growth, flowering, maturing and production of seeds, wintering, seed storage, etc.). Some forage crops could be grown and cultivated on less productive soils and extreme environmental conditions, and this could be their advantage. In order to produce and use forage crops more effectively, new species that are more tolerant to stressful situations must be introduced, as well as wild relatives of conventional species and microbiological fertilizers containing rhizobia and other microorganisms. Plant-based proteins have recently gained popularity as a source of protein, and as many forage plants have a high protein content, they can be used in this quickly expanding industry.Item Short communication: Morphological description and molecular detection of Pestalotiopsis sp. on hazelnut in Serbia(Instituto Nacional de Investigacion y Tecnologia Agraria y Alimentaria (INIA), 2017-07-10) Vasic, Tanja; Jevremović, Darko; Krnjaja; Leposavić, Aleksandar; Andjelković, Snežana; Živković, Sanja; Paunović, SvetlanaIn autumn 2015, hazelnut plants with leaf blight symptoms were noticed in a commercial plantation in the Province of Vojvodina, Serbia. Symptomatic samples were collected and submitted to laboratory analysis. Based on morphological characterization, the fungus isolated from the material was initially identified as Pestalotiopsis sp. Pathogenicity tests showed that two selected isolates infected hazelnut leaves and fruits that developed symptoms after artificial inoculation. The pathogen was re-isolated from diseased leaves and fruits, confirming Koch’s postulates. Molecular identification was performed with sequence and phylogenetic analysis of ITS, EF1-α, and TUB genomic regions. Phylogenetic analysis confirmed the results of the morphological identification. The detection of Pestalotiopsis sp., a causal agent of leaf blight on hazelnut in Serbia, is one of a few reports of these pathogenic fungi on hazelnut.Item The influence of lead acetate and actinomycetes on germination and growth of vetch plant (Vicia sativa L.)(Agricultural Research Communication Center, 2018-10-10) Trajkovic; Kostic; Jaksic, Tatjana; Vasic, Tanja; Andjelković, Snežana; Babić, Snežana; Stamenov, DraganaThe influence of different lead acetate concentrations (10 -5 M, 10 -4 M, 10 -3 M, 10 -2 M and 2 x 10 -2 M) both with and without presence of actinomycetes on germination and initial growth (root, leaf length and stem height) of vetch plant (Vicia sativa L.) was rated. Different lead acetate concentrations and actinomycetes (Streptomyces sp.) of 5, 7 and 9 breed’s types were used to treat vetch plant seeds. It was perceived that high lead acetate concentration of 2 x 10 -2 M has inhibitory effect on the studied parameters. Probes with the highest concentrations of lead with the presence of actinomycetes as much as 60% more seeds germinated compared to the probes without actinomycetes. Low lead acetate concentrations have stimulating effect on these processes, as applied in the presence of microorganisms, and in probes without inoculation.
