MODELLING AGRICULTURAL PRODUCTIVITY IN THE MANAGEMENT OF THE PRODUCTION COMPONENT OF ECONOMIC SECURITY OF AGRIBUSINESS

Abstract

The article carries out an intersectoral study of the influence of meteorological and agrotechnical factors on the productivity of agricultural production (on the example of sugar beet) as a key indicator of the production component of the economic security of agribusiness. It is determined that in the framework of the experiments carried out to increase the productivity of sugar beet, insufficient attention is paid to the impact of meteorological conditions prevailing in the year of the experiments, which, in turn, may cast doubt on the reliability of the results obtained, for example, in the year of abnormal weather conditions. That is why the article outlines a methodological and practical approach to modelling and assessing the impact of meteorological conditions (uncontrollable factors) and agrotechnical practices - liming and organic fertilisation (controllable factors) - on sugar beet yield. It has been substantiated that the results of the carried-out correlation-regression analysis of the influence of meteorological conditions on the productivity of sugar beet are suitable for practical use and can be useful for conducting an experiment and obtaining a more accurate result of assessing the impact of agrotechnical practices of various nature, considering the factors of influence of weather conditions on the yield of sugar beet. As part of modelling and analysing the impact of agronomic practices - liming and organic fertilisation (controlled factors) - on sugar beet yields, it was proposed to apply such agronomic practices as defecate application (50% of the full rate depending on the hydrolytic acidity of the soil). Based on the results obtained, the models (equations) of dependence of sugar beet yield and digestibility on different doses of defecate and organic fertiliser were built, which will allow making effective management decisions in the field of managing the production component of economic security of agribusiness. Thus, the study identified, evaluated and modelled the impact of meteorological conditions and agrotechnical methods of soil liming and organic fertilisation on the productivity of sugar beet as a key indicator of production security of agribusiness. When conducting research with the use of agrotechnical techniques and determining their effectiveness based on the proposed models, it is important for the operational director (agribusiness director) to assess the meteorological conditions that prevailed in the year of the study.
