Field experiments with soft wheat and malting barley, conducted on sod-podzolic medium loamy soil showed that under the influence of increasing rates of nitrogen nutrition in the leaf juice in the first stem node phase, the concentration of amino acids decreases. This fact is confirmed by high correlation coefficients. There is also a close correlation between the concentration of amino acids in the leaf juice, plant productivity and grain quality indicators. Wheat showed a close negative correlation of the concentration of amino acids in the leaf juice with the weight of 1000 grains, the total content of proteins and gluten in the grain, as well as gliadin and glutenin proteins, and a close positive correlation with the content of water-soluble, non-extractable proteins in the grain and the activity of proteases. The concentration of amino acids in the malting barley leaf juice was negatively correlated with the total content of proteins in the grain, the amount of gordeins, the total activity of amylases, and positively correlated with the test value indicators, grain extractivity, and the content of water-soluble proteins in the grain. The research results indicate that the concentration of amino acids in the leaf juice in the first stem node phase provides for a fairly accurate diagnoctics of nitrogen nutrition and prediction of the quality of soft wheat and malting barley grains.

The cultivation of medicinal plants is currently the main way of providing the pharmaceutical industry with raw materials for obtaining biologically active substances for the production of drugs. The use of natural resources of wild species is decreasing every year for a number of reasons, the biotechnological method has not been properly expanded yet, and in some cases it is possible to reproduce only a part of the complex of target biologically active substances contained in an intact plant. In recent years, a positive growth trend has been outlined in the domestic production of medicinal starting materials of herbal origin. However, there are a number of problematic issues that inhibit the development of medicinal plant growing and lead to a certain stagnation. These are general legislative and organizational problems, as well as deterioration or deficiency of material resources - basic production assets, lack of comprehensive mechanization, shortage of qualified specialists and a number of other obstacles. Nevertheless, the actively growing demand for high-quality raw materials from medicinal plant both in our country and abroad opens up great prospects for the development of medicinal plant production. It should be noted that the analysis of the current state of collection and cultivation of medicinal plants in Russia is poorly developed or is practically absent. The paper examines the current state of medicinal plant production; attempts are made to identify the main problems and possible growth points. Finding solutions to the problems and using the growth points show promise for the transformation of medicinal plant production into an industry with a large import substituting and export potential.

This paper presents the results of studying the productive and physiological properties of carp crosses - interline or interbreed hybrids of the first generation. The resulting crosses have a high potential for growth, metabolism, and non-specific cellular immunity. It was found that the studied cross-breeding combinations produced a heterotic effect, which was manifested in different ways depending on the climate zone, planting density, and feeding. In the “Ergeninsky” cross, obtained from crossing the local scaly and Moldavian mirror lines, the true heterosis in relative growth rate amounted to 85-89%. As compared with the parent forms, it has a higher immune defense against pathogens, judging by the large proportion of Mature segmentonuclear neutrophils. The “Mirror” cross is the result of crossing males of the Moldavian mirror line and females of the Volga frame carp that has a scattered scale cover -100%, body weight significantly exceeds the Moldavian mirror parent form. The cross has a smaller proportion of monocytes and neutrophils in the leukogram, and the content of lysosomal cationic protein in the latter is lower, which suggests that these phagocytes are consumed in the process of immune defense. As compared with the parent forms, the cross has more intensive protein metabolism, which can be proved by the high content of total protein and albumins, ALT activity. The lipid metabolism can be determined by the content of cholesterol. The activity of creatine kinase in the “Volzhsky” cross is 2-3 times lower as compared to the initial groups. The “Volga” cross is a reciprocal interbreed hybrid of the Southern zonal type of the Chuvash scaly carp and the Volga frame carp that has a high level of lipid metabolism.

The purpose of the work is to analyze the dynamics of the biochemical parameters of blood in the interlactation (dry) period in connection with the duration of the service period in the subsequent lactation in cows with different genotypes of the SCD1 gene according to rs41255693. The studies were carried out on Holstein cows with an average milk yield of 9807± 606 kg for 305 days of lactation. Animal genotypes (n = 23) were determined by PCR-RFLP: CC genotype (n = 9) and CT genotype (n = 14). Blood biochemical parameters were analyzed with an interval in the calving date of no more than 20 days: the CC genotype (n = 6) and CT genotype (n = 6). In cows with the CC genotype in the first month of the dry period, the concentration of total cholesterol in the blood was higher (p < 0.05), and AST activity tended to increase (p = 0.08) as compared with animals with the CT genotype. 30-10 days before calving, the total cholesterol content and AST activity in cows decreased (p < 0.05 and p = 0.055, respectively), while in animals with the CT genotype they did not change. Correlation analysis showed that the number of correlation links was three times lower in cows with the CC genotype. The service period of more than 100 days is observed 2.3 times more frequent in cows with the genotype CC. The dynamics of metabolic processes and the peculiarities of the relationships between metabolic components in cows with the CC genotype are less optimal than in animals with the CT genotype, which may be associated with an increased frequency of a longer service period in cows with the CC genotype.

In the current conditions of economic development for many organizations operating in the field of agriculture, there are a number of uncertainties due to the lack of strategic planning of activities. On the other hand, it is the long-term goal setting that allows organizations to conduct highly effective activities and be competitive in the market. The main areas of the strategic planning of activities that ensure competitiveness include: branding (creating mental structures in the consumer ’s mind), the development of a model of marketing relations with consumers and the management of distribution channels. However, strategic planning in the organization is possible only on the basis of high-quality situational analysis, which is a difficult task for many enterprises due to the significant financial and labor costs. An equally important aspect is the unwillingness of managers of organizations to invest in marketing assets, primarily due to their unability to determine the effectiveness of these investments, as well as the lack of resources themselves. The authors believe it is necessary to provide significant support to organizations of small and medium-size forms of ownership in order to increase their competitiveness, which can be carried out by establishing regional marketing centers, the main task of which is to provide assistance in conducting a situational analysis of the organization ’s activities, in particular the macro - and micro-environment of the organization, and determining strategic areas of activity. Equally important is the assistance in the preparation of business plans, in particular, the possibility of obtaining funding for the implementation of state program activities, training in the aspects of conducting effective activities, organizing contests, exhibitions and other events.

In 2021, the scientific community celebrates the 95^th anniversary of Ida Pavlovna Kalinina (1926-2015), the academician, Honored Scientist of the Russian Federation, Doctor of Agricultural Sciences, Professor, the most famous scientist in Russia and abroad. In 1951, she graduated from the Fruit and Vegetable Faculty of the Timiryazev Agricultural Academy and devoted 64 years of her life to working for the benefit of domestic horticulture in Siberia. She started working as a junior researcher, and since 1967, for almost 30 years, headed the leading Research Institute of Siberian Horticulture named after M.A. Lisavenko. During this time, under her scientific guidance, domestic assortment and cultivation technologies were developed for 14 garden crops.
