08.00.13 Mathematical and instrumental methods of Economics
DescriptionThe article considers an approach to managing the production process in agriculture based on modeling and evaluation of added value chains. The work has proposed a scheme of links for the production chain of added value creation that contains source control and financing cash flow which comes first in the link of agricultural production, then produced products are supplied to the accumulator, and from there it sequentially passes through the links of the value chain of the cyclic processing facilities, from which finished products are marketed and the resulting revenue is directed to the source of funding and management. We have given mathematical descriptions of the movement of financial and material flows in the links of the developed value chain, and mathematical models for calculating the volume of material and financial flows are proposed. Financial flows were also investigated to compensate for the cost of converting material flows and their mathematical descriptions. The article obtains a mathematical model of the economic efficiency of the production process and proposes a mathematical model for calculating the minimum price for socially significant processing products

06.01.01 General agriculture, crop production (agricultural sciences)
DescriptionThe article studies the effect of various agricultural practices on the yield of two sunflower hybrids (Fortimi and N4LM 408) in the experiment. The studies were carried out in the central zone of the Krasnodar Region on the experimental fields of the JSC "Agrocomplex", Vyselkovsky district in 2018-2019. The experience was laid down according to the triple experience scheme (factor A - the primary soil cultivation techniques; factor B - sunflower hybrids; factor C - herbicides). It was found that with the change of technology (the method of soil preparation and the use of herbicides), the weed infestation of crops changed and a minimum number of them was noted on the variants where postemergent herbicides were used (Euro-Laytning and Hermes). The maximum yield was obtained using chisel and disk plowing with the treatment of sunflower crops with the herbicides Euro-Light and Hermes. There was an increase in yield compared with plowing and these changes are mathematically valid

CHARACTERIZATION OF THE LIFE CYCLE OF A SCIENTIFIC ORGANIZATION
05.13.10 Management in social and economic systems
DescriptionOn the example of economic analysis, we have characterized the life cycle of a scientific institution, the history of the formation and development of which covers almost a three-hundred-year period. The article determines features of the methodology for identifying the stages of the life cycle of a scientific organization and identifying factors that determine the stage of the life cycle
