- Ustanova vodi poreklo od Uglednog dobra i vrta formiranog 2. februara 1884. godine odlukom Podružine kruševačke Srpskog poljoprivrednog društva na Drugom glavnom zboru a “na osnovu tvrdog uverenja da se neposrednim primernim radovima na oglednim dobrima, najjače i najbrže može dejstvovati na unapredjenje poljoprivrede narodne”. U toku svoje istorije, menjani su nazivi i delimično nadležnosti, a od 21. oktobra 1932. godine postaje naučna ustanova spajanjem Agrobotaničkog odseka Poljoprivredne ogledne i kontrolne stanice u Topčideru i Poljoprivredne stanice u Kruševcu

The demand for organic food is rising since consumers want food from reliable, highest quality sources originating from the environment, undisturbed by cultivation and processing. It is necessary to determine to what extent there is a scientific basis for the claims that organic food is of high quality. In this study, beetroot from an organic production system originating from 6 certified organic food producers from different geographic locations was examined. The organic beetroot samples were processed by pasteurization at 70 ºC and 90 ºC into beet juice or by drying at 55 ºC. The following samples were tested and compared: fresh beetroot, pasteurized beet juice and dried beetroot slices. The concentration of vitamin C, level of total phenol compounds (TPC) and antioxidative activity (TAA) in beetroot were influenced by the geographic origin and the applied processing method. The highest degradation for all analysed parameters was found in the samples treated by drying or pasteurisation at 90 ºC. The lowest losses of studied phytochemical components were observed during juice pasteurisation at 70 ºC. The correlation coefficient between TPC and TAA was high and significant (r2 = 0.966).
Multi-location trials and population-based genotyping reveal high diversity and adaptation to breeding environments in a large collection of red clover

Red clover (Trifolium pratense L.) is an outcrossing forage legume that has adapted to a wide range of climatic and growing conditions across Europe. Red clover is valued for its high yield potential and forage quality. The high amount of genetic diversity present in red clover provides an invaluable, but often poorly characterized resource to improve key traits such as yield, quality, and resistance to biotic and abiotic stresses. In this study, we examined the genetic and phenotypic diversity within a diverse set of 395 diploid red clover accessions via genome wide allele frequency fingerprinting and multi-location field trials across Europe. We found that the genetic structure of accessions mostly reflected their geographic origin and only few cases were detected, where breeders integrated foreign genetic resources into their local breeding pools. Phenotypic performance of accessions in the multi-location field trials revealed a very strong accession x location interaction. Notably, breeding material and cultivars generally performed well at the location where they were developed. Local adaptation was especially prominent in Nordic red clover accessions that showed a distinct adaptation to the growing conditions and cutting regime of the North. Our results confirmed that red clover cultivars were bred from regional ecotypes and show a narrow adaptation to regional conditions. Our study can serve as a valuable basis for identifying interesting material that express the desired characteristics and contribute to the adaptation of red clover to future climatic conditions.
Forage Cultivation Under Challenging Environment
(Springer Nature Singapore, 2023) Milenković, Jasmina; Petrović, Mirjana; Andjelković, Snežana; Mitra, Debasis
We 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.
Quality Parameters and Antioxidant Activity of Three Clover Species in Relation to the Livestock Diet
(University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, 2016-06-14) Petrović, Mirjana; Stanković, Milan; Anđelković, Bojan; Babić, Snežana; Zornic, Vladimir; Vasiljević, Sanja; Dajic Stevanovic, Zora
Products of metabolism that are directly involved in growth, development and reproduction and also secondary products of metabolism were studied in 16 natural populations of three species of the genus Trifolium (T. repens – four populations, T. alpestre – three populations, T. pannonicum – nine populations), collected from the central Balkans region, i.e. territory of Serbia. Statistical analysis showed the presence of variability in all species of the test material. The best quality of dry matter, estimated by the ratio of crude protein and crude fiber, was achieved in the populations of white clover. In this species, average protein content was 216.4 g kg-1 while the average content of crude fiber was 222.4 g kg-1. The highest average content of total phenols (77.9 mg GA g-1), flavonoids (159.7 mg Ru g-1) and antioxidant activity (70.2 μg ml-1) was measured in populations of T. pannonicum by phytochemical analysis of aerial parts of plants. The content of secondary metabolites and antioxidant activity in other species were extremely low. Populations of T. pannonicum were notable for fodder quality and antioxidant activity: CS091 with 186.2 g kg-1 of crude protein and antioxidant activity of 55 μg ml-1; RA123 with 175.6 g kg-1 of crude protein and a high level of antioxidant activity of 44.8 μg ml-1. It can be concluded that the selection of these populations may lead to creation of different varieties of fodder crops that could give safe animal feed and would be suitable for growing under adverse conditions of mountainous climate.
Effect of Nitrogen Fertiliser and Lime on the Floristic Composition, Soil Microbes and Dry Matter Yield of Danthonietum calycinae Grassland

Natural 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.
