The aim of the research is to determine ways to improve the efficiency of grain materials pneumatic separation based on the study of the interaction mechanism of grains with the air flow in the channel elements, which are inclined sections of the air duct. The paper considers a modified separation method that separates the grain material according to the aerodynamic properties of the components in a vertical zigzag air channel in an aerodynamic and gravitational field. The studies were carried out by means of mathematical modeling followed by experimental confirmation of the modeling results. A computer mathematical model was created in the MathCad 13 application package to determine the parameters of the zigzag aspiration channel. This model describes the influx of parameters in the channel (width, height, cut of the zigzag ledge to the horizon, edge of the zigzag ledge) on the nature of the grain trajectory. As a result of the numerical simulation process using the mathematical package Mathematica, dependence was obtained to determine the trajectory of motion depending on the angular velocity. An increase in the pneumatic separation effect during the grain mixtures division due to the influence of the Magnus effect was established as a result of experimental studies. The design of a zigzag separator with an annular channel section has been improved based of the research carried out.

The tomato ( Solanum lycopersicum ) is a crop that is characterized by considerable nutrient export because of its intensive growth, development, fruiting, and high biomass production. The purpose of this study is to determine how single-dose and split potassium fertilization impact the overall amount of nitrogen, potassium, and phosphorus exported from soils during crop harvest. A field experiment was carried out on Fluvosol (FAO, ISRIC World Soils) with K 2 O content of 20.3 mg/100g, P 2 O 5 content of 5.8 mg/100g, and mineral N of 19.6 mg/kg. It was found that the biological yield and N, P 2 О 5 and K 2 O nutrient export are significantly influenced by planting time and potassium fertilization treatments. Higher tomato fruit and biomass yields (61878.9 and 27184.9 kg/ha), along with higher nutrient export rates were observed in mid-early tomato plants. The highest yield and total N, K 2 O and P 2 O 5 export from the soil was measured at split potassium (К 80+80+80 ) fertilization treatment. A positive linear correlation between yield quantity and nutrient export was observed. The biological yield and nutrient export were shown to be significantly impacted by potassium fertilization ( P <0.05).

Garlic is valuable crop that is used not only for human consumption, but also in pharmaceutical, food and cosmetics industries. Indigenous cultivars have specific beneficial properties that could be permanently lost due to cultivation of new cultivars. Aim of this study was to established two indigenous garlic cultivars in vitro under influence of growth regulator and light. Garlic varieties Slavonian winter (Croatia) and Vincek (Slovenia) were introduced on medium supplemented with two different concentrations of BAP (1 and 1,5 mg/L) and grown under two types of light (FLUO and LED). Results showed there were no significant influence of light type but concentration of growth regulator significantly influenced in vitro development of garlic microshoots of both investigated cultivars. The best treatment for Vincek garlic explants was nutrient medium supplemented with 1.5 mg/L BAP and LED lights, while for Slavonian winter garlic the best treatment showed to be FLUO light and 1,5 mg/L BAP.

Selenium (Se) is an essential element for human health in trace amounts but is harmful in excess. Most plants contain a fairly low Se and crop Se supplements ensure adequate levels for human nutritional needs. Food is the primary source of Se for humans and due to differences in eating habits, its intake varies considerably. In the human body, selenium deficiency can lead to diseases of the endocrine, musculoskeletal, cardiovascular, reproductive, nervous and immune systems. Selenium is an important ingredient in glutathione peroxidase, the main cellular antioxidant enzyme, which can convert free radicals into peroxides, while vitamin E removes free radicals and neutralizes their potentially harmful effects. Excessive amounts of selenium in the human diet are considered toxic, causing liver and kidney damage, blood clotting, heart and liver necrosis, skin lesions, nausea, vomiting, and loss of hair and nails. Semiconducting properties of Se make it of special value for industry. Selenium is a rare element on the planet, and is a non-renewable resource due to its non-efficient and difficult recycling. Except of coal, which is commonly enriched in Se, there are no ores which could be mined for it. Herewith, the world's scarce Se resources need a careful management, monitoring, recycling, and stockpiling for future generations. The first part of this review outlines selenium concentrations in soil, water, and plants in terms of essential and toxicological effects on animals and humans, while the second part briefly overviews novel biotechnological methods of bioremediation of environmental selenium.

Soybean (Glycine max L.) is a very important legume in the human diet as well as fodder crop. Previous studies have reported that co-inoculation with PGPR (plant growth-promoting bacteria) and rhizobia promotes symbiotic nitrogen fixation efficiency, increases plant nitrogen content and reduces the occurrence of soybean diseases, thus reducing pesticide use, and protecting the environment. The aim of this study was to determine the impact of co-inoculation of soybean seeds with different strains of nodule bacteria Bradyrhizobium japonicum as well as PGPR (Pseudomonas fluorescens). Indigenous strains of beneficial bacteria used in this research were isolated from different locations in Croatia. Isolates were identified by performing 16S rRNA gene sequencing. The application of different strains of nodule bacteria resulted in a statistically justified effect on all investigated properties, with the exception of root length. A positive influence of P. fluorescens on the increase in shoot dry weight was observed with the co-inoculation with the reference strain B. japonicum and two indigenous strains. The application of P. fluorescens did not show statistically justified differences in any of the investigated properties. Co-inoculation of nodules and PGPR bacteria is a very important biotechnological tool in agriculture, which is why research in this area should definitely be continued and expanded to a larger number of P. fluorescens strains.
大豆(Glycine max L.)是一种非常重要的豆科植物，在人类的饮食和饲料作物。已有研究报道，PGPR(植物促生菌)与根瘤菌共接种可促进大豆共生固氮效率，提高植株含氮量，减少大豆病害的发生，从而减少农药使用，保护环境。本研究的目的是确定不同根瘤菌日本慢生根瘤菌和荧光假单胞菌共接种大豆种子的影响。本研究中使用的有益细菌的本地菌株是从克罗地亚的不同地点分离出来的。通过16S rRNA基因测序对分离株进行鉴定。除根长外，应用不同菌株的根瘤细菌对所有被调查的性状产生统计学上合理的影响。荧光假单胞菌与对照菌株和2个本地菌株共接种，对植株干重的增加有积极的影响。荧光假单胞菌的应用并没有显示统计学上合理的差异在任何被调查的性质。结核和PGPR细菌的共接种是农业中非常重要的生物技术工具，这就是为什么这一领域的研究一定要继续下去，并扩大到更多的荧光假单胞菌菌株。

Unique stomach physiology allows ruminants to utilise any form of dietary nitrogen (N) as a protein source. Ruminant N requirements can be divided into N requirements for microbial fermentation and host requirements for amino acids. Ruminant diets often contain non-protein nitrogen (NPN) compounds, a group of components that are not proteins but can be converted to proteins by rumen microbes. Therefore, NPN compounds in ruminant diets serve as alternative sources of ammoniacal nitrogen (NH 3 -N), which is necessary for the synthesis of microbial protein (MCP) in the rumen. MCP is an important component of metabolizable protein for ruminants and, under certain production conditions, may be the only amino acid source for synthesis of tissues and products. In this manner, ruminants utilise NPN compounds without having enzymes for their degradation. The use of NPN compounds in ruminant nutrition allows for an increase in feed consumption and utilisation, as well as the substitution of protein supplements, which in turn leads to more cost-effective production. However, abrupt supplementation or excessive consumption of NPN could negatively affect MCP synthesis, feed digestion, and animal production. On the other hand, it may lead to animal poisoning and the release of large amounts of N into the environment. Knowledge of N metabolism in the rumen, as well as optimization of its utilisation, sets the conditions for the presumed beneficial effects of NPN compounds in ruminant diets, without adverse effects on animal health and the environment. Therefore, the aim of this study was to summarize the recent literature data on the metabolism and utilisation of NPN compounds in ruminants

The article presents the results of studying the influence of quantitative traits on the barley plant performance. Thirty typical plants were selected for each of the 28 genotypes spring two-row barley cultivars and their height, productive tillering capacity, spike length, number and weight of kernels from the main spike, 1000-kernel weight, and performance were measured. As a result, we found significant positive correlations between the performance and productive tillering capacity and weight of kernels from the main spike. Path analysis showed that the weight of kernels from the main spike had the greatest direct effect on the plant performance (0.61). We have established that the paths “spike length – weight of kernels from the main spike – performance” and “kernel number per spike – weight of kernels from the main spike – performance” are of the greatest importance in select for the barley plant performance.
