The cold-resistant soybean cultivar of the northern ecotype Sayana was selected from the hybrid combination F4 L-2577 × Aldana according to the traits of cold and frost resistance and a reduced reaction for a length of a day. Additionally, the degree of cold resistance of this cultivar was evaluated by the cryosedimentation method. The cultivar Sayana belongs to a very early group of ripeness, which matures in 98 days at the latitude of Krasnodar (45°). In the competitive variety test in 2018–2020 its yield amounted to 1.19–2.10 t per ha. During the agroecological testing of the cultivar Sayana in Irkutsk region at a latitude of 53°, the duration of its vegetative period was 126–133 days with the average yield of 2.95 t per ha, which exceeded the standard cultivar Sibiryachka by 0.43 t per ha. The plant height of the cultivar Sayana at the latitude of Krasnodar was 77–88 cm, in the Irkutsk region at latitudes of 53°, it increased to 105–147 cm. The new soybean cultivar of the northern ecotype Sayana is highly resistant to low temperatures of air and soil during the seedling phase, and has increased productivity in long-day conditions of deficient heat supply and cold stress. This allows it to be cultivated as a main crop in the Central Chernozem, Northern Caucasian, Middle Volga, Lower Volga, Ural, West Siberian and East Siberian regions of the Russian Federation.

The early maturing soybean cultivar Triada was developed as a result of individual selection in F4 from the hybrid combination Belogorskaya × Vilana on differentiating backgrounds for traits of reduced response to day length, cold and frost resistance, drought tolerance. Additionally, the degree of cold resistance of the initial germplasm for the breeding from a cultivar Iney was evaluated by a cryosedimentation method. According to the results of the variety trials of 2019–2020, the cultivar Triada in terms of yield exceeded the standard cultivar Slavia by 0.62 t/ha. The height of plants at the latitude of Krasnodar (45°) is 95–125 cm. The new high-yielding soybean cultivar Triada is highly resistant to low air and soil temperatures, and reacts weakly to nonoptimal day lengths. This allows it to be cultivated as a main crop in the Northern Caucasian, Central Chernozem and Low Volga regions of the Russian Federation, as well as in the Republics of Kazakhstan, Uzbekistan and Kyrgyzstan at geographic latitudes from 40 to 50°.

A three-line sunflower hybrid Nika was developed by hybridization of a simple sterile hybrid Donskoy 59 and a line-restorer of pollen fertility ED 155 at the Don experimental station. It is characterized by high productivity, over the years of testing, it exceeded the control on seed yield by 0.25 t per ha, on oil collection per hectare by 0.16 t per ha. According to the length of the vegetative period (98–104 days), it can be attributed to the middle-early group. Plant height is up to 170–180 cm. The leaves are large, the bubbling is very weak, and serration is large. Heads of medium size when maturing turned down with a straight stem. Achenes are broadly ovate, black with grey stripes along the edges and between the edges. The main distinguishing feature of the hybrid is its high productivity and resistance to the new aggressive races of broomrape (E, F, G) and downy mildew (race 330). The hybrid Nika has been included into the State register of protected breeding achievements of the Russian Federation since 2019 and allowed to be cultivated in the Central Black Soil (5), Northern Caucasus (6), Middle Volga (7), Low Volga (8), Ural (9), and Western Siberian (10) regions of Russia.

The article analyses the problem of different Neolitization origins in specified regions. In early Neolithic Age the contacts had a small coverage. Wide-ranging penetration of Lower Volga pin- scratched pottery ornamentation tradition carriers into forest steppe refers to VI and V centuries BC. It was caused by natural and climatic reasons. Up to the late Neolithic Age the influence was one-way - from south to north.

In the structure of diseases of the urinary system in children, microbial-inflammatory lesions of the kidneys and urinary tract are 70–80 %. The prevalence of infections of urinary system in children in the Russian Federation is on average 18–22 per 1000 children’s population. The aim of the study was to analyze the spectrum of infectious agents of urinary infection in children and to determine the dynamics of bacterial resistance. We analyzed 330 cases of urinary system infection in children aged from 2 months up to 18 years in two time peri- ods – 2002–2004 and 2014–2016 (n = 114 and n = 216, respectively). Patients of both periods were divided into three groups: the first one – cystitis, the second one – pyelonephritis and the third group – a combination of pyelonephritis and cystitis. An obligatory criterion for including the patient in the study was the presence of a pathogmonic combina- tion of leukocyturia and bacteriuria, 10 5 KOE/ml, for the infection of the urinary system. The main causative agent of urinary infection in children remains E. coli. An increase is marked in the specific gravity of E. coli, Enterococcus spp. and Klebsiella spp., Pr. vulgaris. The study revealed the growth of E. coli resistance to cephalosporins of II, III, IV generations; decreased resistance of Enterococcus spp. to ampicillin and gentamicin. In the study of the sensitivity of Klebsiella spp. an increase was detected in resistance to cephalosporins of the III generation. We identified the main pathogens of infections of the urinary system and determined bacterial resistance.

The paper presents the results of long-term research on the infl uence of pinching of Northern ecotype soybeans (Okskaya variety) on yield, protein, and oil productivity in high latitudes (57°), a long day, a limited amount of active temperatures (1700…2000 °C) on sod – podzolic soils of the Non-Chernozem zone of the Russian Federation. The authors determine the prospects of using the method for varieties of an indeterminate type of growth. The pinching of crops was carried out three times: at the beginning of the fl owering phase, in the middle of the fl owering phase, and at the beginning of the bean formation phase. It was found that the pinching of crops carried out at the beginning of the bean formation phase, reduces the duration of the growing season by an average of 15 days. The technique ensures a more than double increase in the number of side shoots. The share of the coarse fraction of seeds was about 89%, the yield of seeds reached up to 2.00 t/ha, the protein content in seeds – up to 42.2%, fat – up to 19.1%, protein collection from the seed yield – up to 0.834 t/ha, essential amino acids in protein – up to 0.459 t/ha, fat – up to 0.380 t/ha, collection of unsaturated fatty acids – up to 0.228 t/ha. It is shown that the technique allows optimizing the ripening processes without reducing the productivity and quality of the crop, while the costs of pinching are paid off by reducing the costs of harvesting. The obtained data can be used to optimize soybean growing technologies at the northern border of the soy cultivation

Returns to land, management, and risk were compared where glyphosate and four graminicides (quizalofop-P, fluazifop-P, sethoxydim, and clethodim) were used for johnsongrass control in glyphosate-tolerant soybean. In 1994 and 1995, returns to land, management, and risk for glyphosate-tolerant soybean were highest using glyphosate and lowest using sethoxydim. Break-even analysis showed that yields needed for equivalent returns with any nontransgenic soybean cultivar treated with any of the graminicides could range from 67 kg/ha less to 202 kg/ha more than the yields achieved with glyphosate. Based on this methodology, farmers would increase their return to land, management, and risk by planting glyphosate-tolerant soybean if expected yield from a standard cultivar treated with a standard herbicide program were less than the break-even yield.

The state program “Development of aquaculture (commercial fish farming) in the Russian Federation for 2015-2020” (hereinafter referred to as the State Program) determines the main directions for the development of the fisheries complex and its financial support. However, the current program does not sufficiently elaborate the forms of state support for this sphere of agricultural production, which would contribute to the accelerated development of the industry. It should also be noted that the existing potential of aquaculture in Russia is not fully utilized. The Institute of Economics of the Irkutsk State Agrarian University named after A.A. Ezhevsky, in collaboration with the Ministry of Agriculture of the Irkutsk Region, assessed the fulfillment of tasks of the State Program, identified factors hindering the development of aquaculture in Russia and its regions, and developed recommendations for improving the forms of state support for economic entities in the industry.

Aim. The aim was to develop an integrated online and updated geographic information system (GIS) for the systematiza tion and analysis of information on V. cholerae El Tor antibiotic resistance.Material and methods. The method of serial dilutions in a dense nutrient medium (MUK 4.2.2495-09) was used to determine the sensitivity/resistance to 22 antibacterial preparations of V. cholerae O1 El Tor strains isolated from people and from aquatic environmental objects in Russia in 2005–2016. The development of the Internet version of the GIS was carried out using programming languages HTML, JavaScript and PHP and cartographic data obtained from the corporation Rostelecom (Russia) and the community OpenStreetMap.Results. A comparative analysis of the antibiotic resistance of the strains by regions of the Russian Federation and by isolation time showed an increase of strains resistant to streptomycin, ampicillin, rifampicin and furazolidone, the appearance of cultures resistant to nalidixic acid and ceftriaxone, reduced resistance to trimethoprim/sulfamethoxazole in 2012–2016 compared to 2005–2009. In the Stavropol Krai, the isolated V. cholerae O1 El Tor were characterized by resistance to furazolidone (33.3%) and trimethoprim/sulfamethoxazole (100%); in the Primorsky Krai — to ampicillin, streptomycin, rifampicin (7%), furazolidone (43%), trimethoprim/sulfamethoxazole (100%); in the Irkutsk region and Kalmykia, to ampicillin (8.3% and 11%), furazolidone and trimethoprim/sulfamethoxazole (11% and 89%).Conclusion. The GIS developed allows to collect and analyze information on the antibiotic resistance of V. cholerae O1 El Tor, and to select the strains for given properties.
