Authors: Tulinov A G , Lobanov A Y 
Published: February 2022

Abstract
Getting the future harvest begins at the stage of sprouting. Germination, periods between phenophases, and development of stolons depend on their formation. There are two main types of potato sprouts - light and shadow. The former are preferable for mechanized planting, the latter provide better conditions for potato growth. The regulation of the emergence of sprouts and their development in the pre-planting period is an important problem in agriculture. The purpose of our research was to identify the regularities of the influence of the main methods of vernalization (heating and irradiation with a light flux) on the emergence of sprouts and their further growth. The studies were carried out according to the Box-Behnken plan of the second order for a four-factor experiment, where the response function is the average time of appearance of all sprouts, the number of awakened eyes, and the length of sprouts by the end of the study. As the factors of variation, the temperature of heating tubers for 40 seconds (variation interval 30-40 °C) and three light spectra (variation interval 0-120 seconds) were chosen: 440-485 nm (blue), 500-565 nm (green), 625-740 nm (red). As a result of research, it was revealed that with the help of a single heating at a certain temperature and illumination with light spectra, it is possible to regulate the appearance and further development of shoots on potato tubers by inhibiting or stimulating them. The most optimal parameters for increasing the number of awakened sprouts in the shortest possible time and increasing the rate of sprout development have been determined: heating tubers at a temperature of 35 °C with irradiation with a light flux with a wavelength of 460-475 nm, 550-565 nm, 685-700 nm - 60 seconds.

Authors: Kuzikova I L , Medvedeva N G 
Published: February 2022

AbstractThe actinomycete Streptomyces flavogriseus MK17 was isolated from the soil; it exhibits antagonistic properties with respect to phytopathogenic microorganisms. The MK17 strain produces an antibiotic complex containing polyene and non-polyene components. A crude antibiotic complex with high antifungal activity was isolated from the biomass of the producer. The minimum inhibitory concentrations of raw material for phytopathogenic fungi range from 10 μg / ml to 150 μg / ml, depending on the test cultures. Treatment of soft wheat seeds (Tríticum aestívum) with a solution of raw antibiotic had a positive effect on germination and stem length of the test culture. A wide spectrum of action and a high level of biological activity against phytopathogens in combination with the revealed growth-stimulating effect makes it possible to consider the strain Streptomyces flavogriseus MK17 as a promising candidate for the creation of multifunctional preparations in the field of plant protection.

Authors: Smirnova V V , Sidelnikova N A , Nikitina E N 
Published: February 2022

AbstractThe quality of the grain depends on many factors. The main factors affecting the technological quality of grain are the relative humidity, temperature and duration of storage. The article examines the grain quality of winter wheat varieties Odesskaya 267, Belgorodskaya 16, Moskovskaya 39 immediately after harvesting, as well as during storage for three months. The quality of the grain was determined by the main technological indicators: the mass fraction of gluten, its quality, the falling number. It was found that the quality of grain of all studied varieties improves during storage. The main changes in grain quality in terms of the mass fraction of gluten, its quality, and the falling number occur in the first 1.5 months of grain storage due to the completion of the synthesis processes.

Changes in some indicators of growth, development and quality of eggplant in unheated greenhouses when using nanosilicon
Authors: Avdeenko S S , Avdeenko A P 
Published: February 2022

Abstract
The article evaluates the data on the effect of foliar feeding and soaking of eggplant seeds with various dosages of Nanosilicon when grown in ground greenhouses of the Rostov region. The data show the effectiveness of the preparation Nanosilicon at a dose of 0.35 g / kg for soaking seeds in increasing the height of plants and the average weight of fruits. The maximum values were noted in height for the Lilac Fog and Solaris varieties, and in weight for the Robin Hood variety. It was found that varietal characteristics are of decisive importance in the formation of the average mass of fruits, and the use of the Nanosilicon preparation for the treatment of vegetative plants is more effective than for the treatment of seeds, while an increase in the dose to 0.40 g / kg of seeds and 120 g / ha does not lead to the expected increase in the average weight of fruits. The varieties and hybrids had a high marketability of the yield - more than 90%, reaching a maximum in the Pelican and Violet Miracle hybrids - 98.5-99.0%. An increase in the dosage of nanosilicon application both for seed treatment and for the treatment of vegetative plants insignificantly increases the marketability of fruits. The data obtained indicate a greater efficiency of foliar dressing in comparison with soaking seeds, and an increase in the dose of nanosilicon when soaking above 0.35 g / kg and 110 g / ha when treating vegetative plants is not effective.

Authors: Avakimyants E V , Gordeev V V 
Published: February 2022

Abstract
Protein-mineral-vitamin supplements in the diet of cattle, in particular cows, help to increase the fat and protein content in milk, milk yield and feed conversion, and some types of additives can reduce carbon dioxide and methane emissions. The main problem of the effective use of additives is the uniformity of their distribution, due to the small amount in the total feed mixture, the total weight of additives in the diet is 1.5-2%. One of the directions for solving the problem is the development of a mixer for preliminary mixing of additives, the parameters of which are difficult to justify without studying the physical and mechanical properties of mixtures of additives. Using standard techniques and developed laboratory installations, the physicomechanical properties of mixtures of feed additives for cows used in the diets of two farms in the Leningrad Region were determined. It was revealed that more than 80% of the particles of the mixtures have sizes in the range of 0.75-0.105 mm, the bulk density of the mixtures was 905 and 911.3 kg / m3, the moisture content was 8.14 and 4.44%, the angles of repose of the mixtures were 34, 17° and 34.83°, caving angles - 25.6 ° and 25.9°, internal friction coefficients - 0.76 and 0.7, external friction (on steel) - 0.5 and 0.49. Studies have shown the similarity of the physical and mechanical properties of the mixtures, even under the condition that the proportions and properties of individual additives are different. This allows us to consider the possibility of using the average values of the indicators of physical and mechanical properties when justifying the parameters of technological equipment for mixing, transporting and storing feed additives for cattle.

Published: February 2022

Abstract
Measurements of the structural and mechanical characteristics of food products are important in the food industry, where rheological parameters provide information about the quality of the finished product. In this paper, the influence of the parameters of the homogenization process (rotor speed, homogenization time) on the rheological properties of mayonnaise with 76% oil phase is investigated. For the manufacture of mayonnaise, two types of vegetable oils were used: refined sunflower oil and cold-pressed linseed oil. The mechanical process of homogenization of mayonnaise was carried out at different rotor speeds and homogenization times at room temperature. Mayonnaise is prepared on a laboratory disperser (rotor / stator system) according to a traditional recipe without adding a preservative, which limits the shelf life of the product. Measurements of the rheological properties of mayonnaise were carried out on a rotary viscometer at room temperature. According to the data obtained, rheological parameters were calculated: apparent viscosity, consistency coefficient and flow index. Research results show that the parameters of the homogenization process affect the rheological properties of mayonnaise. As the frequency of rotation of the rotor and the duration of the homogenization process increase, the rheological characteristics of the mayonnaise change.

Abstract
The article discusses the development of a MIMO antenna array for networks of the fifth generation of millimeter wave ultra-wideband data transmission. The antenna system is designed to form base stations that are integrated into solar panels designed to generate electricity for backup power supply of network equipment or for other consumers. Implementation of the antenna array based on the proposed design allows for beam formation and control of the direction of radiation due to synchronous feeding of antenna elements with different phases. When forming a linear antenna array of four antenna elements, it is possible to achieve antenna beam control within the range from -30 to 30 degrees; when forming an array of 2x2 elements, the antenna beam is controlled in two directions, while the deflection range is from -20 to 20 degrees.
State of coenopopulations of Dactylorhiza maculata (L.) Soo. (Orchidaceae Juss.) in disturbed habitats of the Arctic urbanized territory
Authors: Vasilevskaya N V , Putilova N V 
Published: February 2022

Abstract
The paper presents results of studying of coenopopulations of the orchid Dactylorhiza maculata in disturbed habitats of the Arctic urbanized territory. D. maculata has an International Protection rank: the species is included in the IUCN Red Data Book, in Application II to the International CITES Convention. The study of coenopopulations was carried out in the city of Murmansk (68o 58' N; 33°05' E) along the St. Petersburg - Murmansk highway on permanent and temporary test sites. According to the contamination of biotopes by petroleum products and vehicle emissions, the experimental sites were divided into two groups: with high and medium pollution. On heavily polluted wetlands and roadsides, a very high density of orchids was revealed, from 118 to 127 (plants/m2). The ontogenetic spectrum of coenopopulations of D. maculata is left-sided, with a predominance of plants of the pregenerative period (73 - 82%), a "renewal wave" is noted. The share of seedlings, juvenile and immature plants is high. Among age groups, the proportion of blossoming plants of the generative period varies from 18 to 27%. In biotopes with medium level of pollution of environment, the density of D. maculata coenopopulations is much lower (21–27 plants/m2). The high size and density of coenopopulations, germination of seeds under the conditions of environmental pollution by petroleum products and vehicle emissions, the presence of all age states in the ontogenetic spectra, except for senile ones, indicates a high ecological lability of D. maculata. This species can be attributed to the “early colonizers” of disturbed habitats and be used for bioindication of the level of their environmental pollution.
Evolution and adaptation changes in dynamics of local climate systems in the context of climate-ecosystem equilibrium
Authors: Kolokolov Yu , Monovskaya A 
Published: February 2022

Abstract
The paper researches the local climate dynamics by the following way: behavioral potentialities (the so-called ensemble of attractive phase clouds) are reconstructed by processing the annual temperature cycles over the available period of meteorological observations; the recent cases are compared with the ones occurred at the end of the 19th century; tracks of evolution and adaptation changes from the past to the present are determined taking into account the climate-ecosystem equilibrium. This way implies to attract bifurcation and control theories in order to be realized. So, the regulatory hypothesis is used, where the local climate dynamics is associated with the dynamics of a solar energy converter under the astronomically forced hysteresis control with double synchronization (the HDS-control). Thus novel details on local climate become apparent, and these details seem to be important in order to understand tendencies concerning unbalanced climate-related processes towards future.

Published: February 2022

Abstract
Modern living conditions in densely populated cities are associated with various negative anthropogenic factors, one of which is noise pollution. Typically, high levels of noise are associated with urban transport, specifically with the railroad transport. It is difficult to imagine the effective functioning of large cities without this type of transport, considering how many people use it every day. And therefore, it is necessary to understand within what limits is the noise impact caused to passengers by this type of transport and people who live within the range of considered impact. This article is aimed at better understanding of the methodologies for assessing and analyzing noise pollution caused by urban railroad transportation. The northern section of the Moscow Central Circle (MCC) was chosen as the main object of the study.

Published: February 2022

Abstract
Sustainability of arable agriculture is an important issue facing the world nowadays. The last green revolution was achieved with a mix of technologies such as chemistry, engineering and genetics. In the nearest future the need for another green revolution is could be arising but this time with less chemistry being involved as the agricultural sustainability has been degrading. The concern is massively increased for the last decades because everyone has been trying to increase agricultural production substantially but the environment has not been paid much attention. Analysis of different factors influencing the arable agriculture is key assumptions that help to understand future agricultural sustainability. Hence it is possible to identify the new targets and toward which investment must be prioritised. There are many factors that can be contributed to effect of arable agriculture but only some of them are considered in this essay which ranked as being more crucial than others. These are believed to be genetic improvement in plant breeding, adapting new policies and wise management of farming. Conclusion is that breeders and managers in agriculture must work more closely is the enormous challenge of global sustainable productivity is to be met.
On the issue of normalization of maximal permissible input of suspended matter into water bodies
Authors: Popov A N 
Published: February 2022

Abstract
B Analysis of the currently used system of normalization of the suspended substances (SS) input into water bodies has shown that it is based only on fishery norms of maximal permissible concentration set in laboratory conditions for neutral SS. The detailed analysis has demonstrated that SS can contain organic and non-organic ingredients with not only mechanical impact on hydrocoles but with the impact upon hydro/chemical characteristics of water bodies due to transformation because of the inter-water body processes influence. Besides, they act as carriers of the adsorbed pollutants including high-toxic ones, as well as initiators of bottom sediments (sources of secondary pollution) formation. A number of authors who deal with ecosystem impact of suspended substances and consider chemically neutral SS have proposed regulation of discharge based on the pollutants’ impact on fish families according to the results of long-time observations of the fish behavior under the neutral suspended substances’ impact. Analysis of the current situation demonstrates that now there is practically no aggregated assessment of the suspended substances impact on the water bodies’ status. There is only differentiated estimation of the impact of only the one class of suspended substances ("chemically neutral") though it is quite inadequate in respect of the current situation. In fact, there is practically no well-grounded norms of suspended substances discharge to water bodies to take into account the whole spectrum of the SS impact upon water bodies.

Published: February 2022

AbstractThe purpose of the study is to establish the regularities of the formation of maximum flow rates and erosion under the influence of forests, forest strips and agricultural lands in the steppe of the Volga upland. The research methodology was based on the recommendations of specialized research institutes and scientists of Russia. Snow water supply, runoff, maximum runoff modulus, erosion undergo significant changes under the influence of agricultural land, forest strips and forests. Forest strips and forest reduce the coefficients of spring and stormwater runoff in comparison with agricultural land by 5.0-13.5 times. Accordingly, the indicators of the maximum flow modulus are 17.6 - 157 times. The parameters of the drain module are necessary for the creation of discharge erosion control structures. Erosion under the influence of forest strips in fields with non-fallow crop rotation cultivation technology and from forest lands takes permissible sizes of less than 0.3 t/ ha for soils A+ B < 0.5 m. Dump technology, in addition to forest strips, requires the use of additional agrotechnical techniques, for example, mulched crevice. From the complex variety of the impact of natural and anthropogenic factors on erosion, the coefficient and modulus of surface runoff, the degree of protection of the soil by land are the predominant ones. Regression-correlation analysis notes a close relationship between erosion, surface runoff parameters and applied forest strips with determination coefficients 082-0.96. Long-term studies on slopes 3-5o allowed us to recommend: distances between forest strips 300 m- 250 m; non-fallow technology of crop rotation cultivation.
