  • 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

Quality of alfalfa (Medicago sativa L.) and red clover (Trifolium pratense L.) mixture silages depending on the share in the mixture and additives

Alfalfa silage has a high potential for improving ruminant nutrition. A problem that frequently occurs during its preparation is the process of proteolysis, which could partially be avoided with the use of certain techniques and materials. Red clover, often used in form of silage, expresses weaker proteolysis due to the possession of certain chemical compounds. This research was conducted to study the effects of ensiled alfalfa and red clover mixtures, mixed at different ratios (100:0, 90:10, 70:30, 50:50, 30:70, and 0:100), as well as the influence of additives – two doses of oak tannin extract (6 g kg-1 DM and 12 g kg-1 DM) and bacterial inoculant (Enterococcus faecium, Bacillus plantarum, and Bacillus brevis) on fermentation parameters and protein fractions of the silages. The treatments which contained any of the used percentages of red clover, as well as the ones which received the higher dose of oak tannin (12 g kg-1 DM), reduced the ammonia nitrogen content, which is one of the main indicators of proteolysis. On the other hand, considering non-protein nitrogen, as another of the indicators of proteolysis, there was no positive sign of the contribution of red clover to the reduction of proteolysis in alfalfa, and neither there was a significant impact of additives that were applied in this experiment.

Fertility and chemical composition of forest soils covered with Allium ursinum L. In Serbia
(Parlar Scientific Publications, 2022-04) Željko, Dželetović; Simić, Aleksandar; Marković, Jordan; Andrejić, Gordana; Denader, Tijana; Babić, Snežana
A. ursinum is a wild growing species, which is often found on various localities throughout Serbia, primarily within forest and occasionally on meadow. Fresh picked leaves and bulbs are used for preparing a salad or meals. For this research we have collected and analyzed soil and plant material from 12 different locations in Serbia. The analyses of basic fertility of soils have shown that A. ursinum grows mainly on acidic and soils containing high percentage of humus, with high total nitrogen content, low to medium supplies in available phosphorus and high supplies in available potassium. In those soils there is a very strong correlation between the total N content and total organic C (0.931). There is a relatively wide range of concentrations of overall Cd, Co, Cr, Cu, Ni, Pb and Zn in soils on which A. ursinum grows. The translocation factor for A. ursinum is TF ≥1 has been calculated for Cd, Pb and Zn.

Protein fractions as influenced by cultivars, stage of maturity and cutting dates in alfalfa (Medicago sativa L.)
(Agricultural Research Communication Center, 2019-05-08) Marković, Jordan; Petrović, Mirjana; Terzić, Dragan; Vasić, Tanja; Kostić, Ivica; Štrbanović, Ratibor; Grubić, G.
This study was undertaken to determine the relationship between CNCPS (Cornell Net Carbohydrate and Protein System) protein fractions and in vitro RUP (Rumen Undegradable Protein) concentration and the variability of protein fractions among alfalfa cultivars grown in Serbia. Two cultivars of alfalfa (Medicago sativa L.) – Serbian cv K 28 and American cv G + 13R + CZ were sampled at three stages of maturity. Comparing the two cultivars of alfalfa (K 28 vs. G + 13R + CZ) means, there were significant differences in all protein fractions. Two investigated alfalfa cultivars differed significantly (p less than 0.01) in RUP content, cv G + 13R + CZ was higher in RUP than cv K 28. Stage of maturity had an effect on proportions of the protein fractions. From a nutritional and breeding point of view, cultivar such as G + 13R + CZ is desirable because it combine higher CP (Crude Protein) values with lower protein degradability than cv K 28.

Morphological and Chemical Characterization of a Collection of Mountain Clover Natural Populations
(Institutul Național de Cercetare Dezvoltare Agricolă Fundulea, 2022) Petrović, Mirjana; Lugić, Zoran; Zornic, Vladimir; Andjelković, Snežana; Tomić, Dalibor; Milenković, Jasmina; Jevtić, Goran
With climate change evident, the possibility opens up of introducing into production a species that, although not characterized by high yield, nevertheless offers some other benefits for both the environment and man. One of these species is mountain clover (Trifolium montanum L.), a species widespread around European in the past, but due to agricultural activities its habitat has become fragmented and areas of mountain clover impaired. In the present study, the collection of nine natural populations of mountain clover originating from different parts of the hilly-mountainous areas of Serbia was tested in field conditions. We analysed different morphological traits (green plant biomass, stem length, internode number, number of lateral branches, leaf length and leaf width), dry matter quality traits (content of crude proteins, crude fibre and crude fat) as well as secondary metabolites (total phenolic content, flavonoid contents and antioxidative activity). We collected morphological data and plant samples during 2011 and 2012. We performed descriptive statistics to provide basic information about variables in the dataset, then calculated Shannon-Weaver diversity index (H’) and performed two-way ANOVA and principal component analyses (PCA). Analysing the broad range of data collected during two years, we found considerable morphological and chemical diversity amongst the collection of mountain clovers from central Serbia. Mean coefficient of variation (CV) in the morphological dataset ranged from 18% (stem length) to 57.6% (plant biomass) in 2011 and from 16.5% (leaf length) to 70.6% (stem number) in 2012. Dry matter (DM) parameters displayed the lowest CV, ranging from 6.1% (crude proteins) to 14.8% (crude fat), indicating that these parameters were less discriminative within the study collection. Over all populations, average crude protein content was 19.5%, and average crude fibre content was 27.3%. Total phenolic contents (expressed as gallic acid equivalent, GAE) ranged from 49.8 to 89.7 mg GAE g-1 DM, and flavonoid contents (expressed as rutin, Ru, equivalent) ranged from 66.8 to 142 mg Ru g-1 DM. Average antioxidative activity expressed in terms of IC50 values ranged from 177 to 426 mg ml-1 of methanol extract.
