- 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

Analysis of the weed flora in the vegetable gardens in the village of Trmčare (Kruševac municipality) revealed the presence of a total of 44 weed species [23 weed, 19 weed-ruderal, 1 ruderal and 1 weed of meadows and pastures]. The recorded weed flora is dominated by representatives of the class Magnoliopsida (dicotyledons, broad-leaved weeds) with 38 species, while only six species are present from the class Liliopsida (monocotyledons, grass weeds). The analysis of life forms of weeds recorded in vegetable gardens shows a dominance of therophytes (70.45%), compared to geophytes (13.64%). Meanwhile, hemicrypthophytes make 11.36% of the weed flora and thero-hemicrypthophytes only 4.55%. The number of weeds was not high, because the inter-row cultivation was done every ten to fifteen days, and weeds were manually removed in the rows, around the plants. Regardless of the mechanical removal of weeds, the diversity of the weed flora was not negligible. In all observed vegetable gardens under organic production, the most frequent winter weeds were: Camelina sativa (L.) Crantz., Poa annua L., Myosotis arvensis (L.) Hill., Veronica persica Poir., Cerastium glomeratum Thuill., Lamium purpureum L. Of the early spring weeds the most frequent were Chenopodium polyspermum L., Polygonum lapathifolium L., Polygonum persicaria L., Polygonum convolvulus L, and Galium aparine L., and of the late spring weeds the most often present were Chenopodium album L., Amaranthus retroflexus L., Amaranthus hybridus L., Setaria viridis (L.) P. B., Hibiscus trionum L., and Portulaca oleracea L.

A major problem when establishing alfalfa crops can be the presence of weeds. In intensive systems, weeds are controlled with herbicides, which inevitably contaminate water, soil, air, and food. The work aimed to carry out a comparative analysis between the intensive system of alfalfa cultivation with herbicide use and the cultivation method without herbicide use in order to be able to make recommendations for the development of sustainable management systems in agriculture. A field trial was conducted at the experimental field of the Institute for Animal Husbandry, Zemun, Serbia, using a randomized block design with three replications and three treatments: control treatment (without herbicide application), treatment with bentazon and treatment with imazamox. The forage yield and hay yield in the first cut were significantly reduced in the treatments with herbicide application. The application of herbicides led to a significant reduction in weed biomass. The herbicides had different effects on individual weed species and their proportion in the total weed biomass. The application of herbicides gave no significant reduction in the number of weed species present. The number of weed species decreased over time due to the competitiveness of alfalfa. Under conditions of appropriate agrotechnics, the alfalfa crop can be established without using herbicides, which could be a good practice for sustainable farming systems. In this case, increased weed emergence can be expected in the first cut, which should be used carefully, and a reduction in weed levels can be expected with each subsequent cut.

This study presents the findings from assessing the quality of alfalfa seeds collected from three Serbian regions: in each region, batches of seeds from six places were analyzed. The following criteria were investigated: the proportion of dormant seeds, the germinated seed content, the proportion of dead seeds, and the percentage of aberrant seedlings. Seed quality was assessed after six, eighteen, thirty, and forty-two months of storage. The highest seed quality was obtained after thirty and eighteen months of seed storage (91% and 89% of germination, respectively). During the 42-month storage period, the percentage of dead seeds (8%) and abnormal seedlings (7%) increased, while germination declined to 84%. In a storage period of six months, the participation of dormant seeds of 21% affected the germination rate, which was 77%, regardless of the low proportion of dead seeds (1%) and abnormal seedlings (2%).
Transitional hosts of phytopathogenic fingi in organic vegetable production

In practice, many weeds are frequently overlooked as sources of infection with a variety of plant diseases. This is especially true for diseases whose causative agents are transferred by weed seeds or can be found on weed roots and plant residues of weeds. Specifically, because most cultivated plants have a one-year life cycle and depart from arable land after harvesting, so do the causative agents of plant diseases. Weeds present a distinct situation. When crops are harvested, no attention is paid to them, allowing them to grow freely on agricultural land. There have been no more detailed studies of the mycopopulation of weed plants in Serbia. In this article, we present the results of preliminary research. Weed plant seed samples were gathered during the summer and autumn vegetative periods of 2023 in a vegetable crop developed using organic production practices. Isolation was performed using standard phytopathological methods. In these investigations on the mycopopulation of weed seeds, 1050 seeds from 21 weed species were investigated. Morphological identification of fungi to genus was performed using standard keys. A large percentage of fungi colonies formed around the seeds of weed plants. In this way, nine different genera of fungi were determined, namely: Penicillium, Fusarium, Albugo, Alternaria, Cladosporium, Bipolaris, Epicoccum, Rhizopus and Mucor.
Concentration of some microelements, their mutual relationship and association with cell wall components in the dry matter of red clover

Minerals are required for virtually all vital processes in the body. A deficiency of each essential macrominerals or microminerals in animals results in abnormalities that can only be corrected by supplementation of the deficient minerals. Forages provide an important source of minerals for ruminants. In some instances, forages may provide adequate quantities of all essential minerals required by ruminants. In other situations, forages are deficient in one or more minerals and supplementation is required for optimal animal performances. The association of certain minerals with fiber or other insoluble plant components could decrease the rate and extent of mineral release from forages in the gastrointestinal tract. Objectives of this study was to determine changes in minerals concentration in dry matter of red clover -- K 39 and K 32 cultivars with advancing plant growth and development in the first cut, and to measure the amount of minerals associated with the cell wall components. Three stages of red clover cultivars -- mid bud stage, early bloom and mid bloom, were examined in the first cut. The experiment was established as a completely randomized block design in three replications. The concentration of Fe, Zn, Cu and Mn were measured by atomic absorbance spectrophotometry. Analyses of variances revealed significant differences between stages of plant development for investigated minerals. The highest proportion of Cu and Mn were associated with cell wall components of red clover.
