The objective of this study was to examine the effect of the variety, locality and year on the morphological and productive parameters of the spelt wheat obtained in the organic production system. Four spelt varieties were grown at three agroecological environment (Pančevo, Bogdanica and Zlatar), in southeast Europe, Serbia. They are used in order to determine general adaptability in different environment in three years trial (2014-2016). Analysis of the selected production parameters of spelt wheat, according to variety, locality and year, were conducted by the Principal Component Analysis (PCA). The PCA of the presented data explained that the first two components accounted 86.02% of the total multivariance in the eleven variable factor space. The results showed that the highest values of a number of plants, number of stems, number of spikes, plant height,the number of grains in the spikes, weight of grains per spike, yield of above ground biomass, harvest index and yield of hulled grain were observed for the crops grown in Pančevo, regardless of the spelt wheat variety and year. The samples grown in Bogdanica showed to be very sensitive to the spelt wheat variety, in terms of hull index value. The highest value of mortality stems has been found in Zlatar, regardless of the spelt wheat variety, or the year.

During the period 2010-2011 about 2.113 million ha of buckwheat was sown annually worldwide. Average yield of buckwheat during the monitored period was 913 kg ha-1. Areas and average yield have a rising tendency. The most significant producers of buckwheat in the world are: China, Russia and Ukraine. In Serbia buckwheat is produced on small areas. The paper presents results of testing of four buckwheat varieties, produced on plots of the Institute for crops and vegetables as follows: Novosadska, Godijevo, Bamby and Češka. Analysis of average yield has shown that Novosadska variety produced statistically significant higher yield (2626 kg ha-1) compared to the other varieties tested (p <0.05). From the results shown we can see that buckwheat yield in Serbia is significantly higher compared with the world average yield, which tells us that this plant can be successfully produced in our agro-ecological conditions of growing.

Roots of wild growing Angelica archangelica L. from Mt. Ozren (Serbia) were subjected to hydrodistillation and GC-MS analysis. The roots contained 0.10% of essential oil with α-pinene (29.7%), δ-3-carene (14.2%), and a mixture of β-phellandrene and limonene (13.2%) as main compounds. The modified resazurin microtiter-plate assay was used to evaluate the antibacterial activity of the essential oil against Staphylococcus aureus and Escherichia coli. The minimum inhibitory concentration (MIC) values were 14.2 μL/mL for S. aureus and 28.4 μL/mL for E. coli, while the minimum bactericidal concentrations (MBC) were 56.8 μL/mL and 113.6 μL/mL, respectively. According to the obtained results, the angelica root essential oil can be applied as a natural preservative in food and as a natural antibiotic for the treatment of several infectious diseases caused by these two bacteria.

Composition of tocopherols, tocotrienols, carotenoids, fatty acids, as well as hydrophilic and lipophilic antioxidant activities, were determined in seeds of two Salvia species and oils obtained from them. Both seeds contained a large amount of oil (around 20%) rich in polyunsaturated fatty acids. While Salvia officinalis seed oil can be classified as oleic-linoleic oil, the predominant fatty acid in Salvia sclarea was α-linolenic acid (around 54%). Among tocols, the main isomers in both seeds and oils were γ-tocopherol, followed by α-tocopherol. Concerning carotenoids, their concentration was around 0.75 mg/100 g of seeds and 0.16 mg/100 g of oils, with a predominance of lutein. Oil and seeds of S. officinalis exhibited higher antioxidant potential compared to S. sclarea investigated samples which could be attributed to higher content of total vitamin E and carotenoids. This study provides results that enables use of two Salvia species as new alternative sources of vegetable oils.
