- 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

In four-year monitoring of two generations of honey bee colonies (queen bees and their offspring), the correlation coefficients between morphological traits for the amount of foraged pollen, traits on which the foraging activity of honey bees depends. Considering morphometric traits, the tongue length, the length and width of the wings and basitarses were measured. In field conditions, scouts and forager bees were counted, the total amount of foraged pollen and the
amount of foraged alfalfa pollen were measured. It was found that there is a very strong correlation between the amount of foraged pollen and the observed traits that determine the foraging activity of the honey bee, as well as the size of the basitarus at a statistically very significant level (p <0.01). There was a strong correlation between the traits that determine the foraging activity with each other (p <0.01). The size of the basitarsus (length and width) was
strongly correlated with most traits. The wing length was in medium correlation with most traits (r = 0.3-0.6), while the wing width with all traits was weakly or negatively correlated. The length of the proboscis was in the medium strong correlation with most of the observed traits. It is weakly correlated with the width of the basitarus and the wing, and weakly to negatively correlated with the wing length.

The aim of this study was to analyze the effect of pre-sowing treatments with different concentrations of gibberellic acid solution, as a growth stimulator, on root and stem growth, seedling weight and nodulation of young white clover plants. The experiment was performed in 2019 in the laboratory for seed seed control at the Faculty of Agriculture in Čačak. Seed of rivendel cultivar were used. Six treatments with gibberellic acid were applied (control, 0.25;
0.5; 0.75; 1.0 and 1.5 mmol L-1 gibberellic acid). Root length, stem length and seedling weight were evaluated. Seedlings from the parallel experiment were planted in containers with substrate and cultivate in the greenhouse.Plants were analyzed 45 days after treatment. The obtained results indicate that pre-sowing treatments with gibberellic acid at a concentration of 1 and 1.5 mmol L-1 can significantly affect more intensive growth of plants of white clover.

The practice of preserving green crops by fermentation as silage has increased dramatically in recent years. Successful ensiling can be difficult due to numerous problems such as: high moisture content, high feed buffer capacity, insufficient amount of fermentable carbohydrates etc. The aim of this investigation was to determine the suitability for ensiling field pea:oat and common vetch:oat mixtures grown at different seeding rate and harvested at different stages of
growth. Field pea, common vetch and oat were grown in pure stands and in the mixtures of 75:25, 50:50 and 25:75 ratios and harvested at three stages of plant development: beginning of field pea and common vetch flowering, forming the first pods in field pea and common vetch and at the forming green seeds in 2/3 field pea and common vetch pods. The most favorable ratio of sugar and buffer capacity for the established level of dry matter in the examined crops was stated in pure oat crop. The results obtained in the mixtures of field pea and oat are based on the ratioof sugar and buffer capacity and can successfully ensile in all three examined relations of germinating grains of field pea and oats. The highest sugar content (182.1 g kg-1 DM) and the highest buffer capacity were determined in the 50:50 field pea:oat mixture at the pea flowering stage of development. The least favorable ratio of sugar and buffer capacity was found in pure
common vetch.
