On the experimental field of the Center for Small Grains in Kragujevac in the two growing seasons 2018/19 and 2019/20. it was analyzed plant height, lodging resistance and grain yield of 10 genotypes of winter wheat (L-25/6, L-56/98, L- 56/7, L-63/7, L-49 / 4, L-23/24, L-246/2, L-191 / 5-9, L-191 / 5-4 and L-36-2). The average annual temperature and precipitation in both growing seasons were above the multi-year average. The highest average yield during two years had the line L-191 / 5-9 (6,485 t ha-1), then L-246/2 (6,415 t ha-1), and the lowest line L- 63/7 (5,846 t ha -1). Wheat genotypes differed in plant height, so the L-23/24 line had the highest value for this trait in both growing seasons, and the L-25/6 the lowest. In the first vegetation season, a slightly higher plant height ranged from 76 cm to 96 cm, and in the second from 72 cm to 90 cm. All genotypes had good lodging resistance in optimum environments.
2018/19和2019/20两个生长季在克拉古耶瓦茨小粮食中心实验田的研究对10个冬小麦基因型(L-25/6、L-56/98、L- 56/7、L-63/7、L-49 / 4、L-23/24、L-246/2、L-191 / 5-9、L-191 / 5-4和L-36-2)的株高、抗倒伏性和籽粒产量进行了分析。两个生长期的年平均气温和降水量均高于多年平均水平。两年平均产量最高的品系为L-191 / 5-9 (6485 t ha-1)，其次为L-246/2 (6415 t ha-1)，最低的品系为L- 63/7 (5846 t ha-1)。小麦基因型在株高上存在差异，因此L-23/24系在两个生长季节的株高值最高，L-25/6系最低。第一植被季株高略高，为76 ~ 96 cm，第二植被季株高为72 ~ 90 cm。所有基因型在最佳环境下均具有良好的抗倒伏性。

Knowledge and understanding of the size and composition of soil weed seed reserves can help in planning a successful and timely weed control strategy and assessing the dynamics of weed emergence. It is very important to have an insight into what percentage of the latent plant community will pass into the active community. The seedling emregence method gives the number and structure of seeds that have passed the dormancy phase. It was determined that in the monoculture of soybean 24.9% of seeds are ready to germinate out of the total estimated weed seed bank, while in the three-field crop rotation 23.61% of seed. The largest number of germinated seeds comes from the weed species Chenopodium albumand Chenopodium hybridum.

The results of a qualitative assessment of the growth dynamics of the microbiota of domestic animals and birds under the influence of probiotic preparations are presented. Seven strains of microorganisms and 14 types of probiotics or their combinations are considered. Polynomial models showed a low quality of approximation of the results. Dynamic models of the first and second orders, taking into account external influences, showed good qualitative agreement with the experimental results. Based on the modeling, several scenarios of the influence of probiotics have been identified: stimulation, suppression, etc. To obtain a quantitative agreement, it is necessary to increase the number of measurements.

This study aimed to examine the effect of different media - Murashige Skoog (MS) and Gamborg (B5) on the growth and development of in vitro seedling cultures of wheat (Triticum aestivum L.). The effects were evaluated through the measurement of root and shoot length, fresh and dry mass, as well as through the determination of the concentration of photosynthetic pigments (chlorophyll a, chlorophyll b, and carotenoids). The obtained data indicate that MS has better effects on the growth and development of wheat seedlings, since longer shoot length, and better fresh weight were observed on seedlings from this type of media. Additionally, higher chlorophyll b concentration and lower carotenoid concentration were measured in wheat leaves grown on MS medium. It can be concluded that MS is more suitable for establishing the initial in vitro culture of wheat compared to the B5 medium.

The aim of this study was to analyze the properties of cold pressed pumpkin and walnut oil. Pumpkin and walnut are plant crops that have a long tradition of cultivation in Serbia, but are insufficiently used for oil production. Cold pressed oils have a high nutritional and market value. The production of cold-pressed oils is more environmentally friendly, simpler, and the oils retain important nutrients, compared to producing oils by extraction and refining. Pumpkin seed oil is characterized by a high content of polyunsaturated fatty acids in relation to the content of monounsaturated and saturated fatty acids. The dominant fatty acid is oleic or linoleic. Oils with a higher proportion of oleic acid are more oxidatively stable. Specifically, pumpkin oil is dominated by the presence of ∆7 sterols, unlike other vegetable oils. Walnut oil is dominated by polyunsaturated fatty acids, with a significant amount of C18:3, which makes it sensitive to oxidation. The oxidative stability of walnut oil is correlated with a decrease in the content of C18:3 fatty acids. The chemical composition of the oil varies significantly depending on the variety and growing conditions in both pumpkin and walnuts. then there is a potential in the determination of suitable genotypes with oil of greater oxidative stability.

In order to assess the impact of the inoculant "BioStabil Plus" on the ensiling process of alfalfa, the parameters of fermentation quality were analyzed (pH, acetic, butyric, lactic acid, ammonia and water-soluble nitrogen in total nitrogen) and chemical composition of silage (crude protein, crude cellulose, crude fats, nitrogen-free extractives and ash), as well as silage quality assessment (DLG and Zelter). Alfalfa biomass in the beginning of flowering phase was ensiled without additives and with the addition of inoculant. The addition of inoculant showed a decrease in pH, increased production of lactic acid, reduced production of acetic acid, with a favorable ratio of these acids (2-3: 1). The introduction of inoculants resulted in improved fermentation quality, which resulted in better preservation of nutrients, especially for crude proteins, since the use of inoculants also showed a decrease in ammonia nitrogen content compared to control (inoculation - 12.28% NH3-N/ΣN, control - 17.42% NH3-N/ΣN). The general conclusion is that inoculant should be added to alfalfa biomass, for the purpose of optimal production of lactic and acetic acid, as well as obtaining higher nutritional value.

Soil fertility is one of basic caracterisitics of every soil tipe and it is a feature that differentiate soil from bedrock. For determination of soil fertility various physiochemical methods are used, primarily for the purpose of applying soil fertilizers in plant nutrition. In this sense, the following parameters of soil fertility were tested in soil samples: pH in potassium-chloride (KCl), CaCO3, humus, total nitrogen, P2O5, K2O. The results of the research showed high soil fertility in a large number of locations that were surveyed, but also the existence of surveyed sites that require the application of pedomeliorative measures.

The paper presents an overview of domestic and foreign research on the influence of lipolytic changes in silage on the content and the composition of milk fat. During the preparation of herbage for ensiling (wilting), some losses occur due to lipolysis and oxidation of fatty acids. During the fermentation of the ensiled mass whereby some strains of lactic acid bacteria (Lactobacillus plantarum AKU 1009a) were used as inoculants, the biohydrogenation of some PUFA occurs as well as the increase of the content of conjugated fatty acids in the silage. Based on a review of a number of experiments, the most favorable effect can be attributed to legume and grass silages, compared to corn silages. In the first place, for sure, is red clover silage, due to the partial reduction of lipolysis by polyphenol oxidase. In contrast, when corn silage is used, there is occurrence of biohydrogenation of linoleic acid in trans- 10, cis-12 CLA, which is a very strong inhibitor of milk fat synthesis.
