The volume of agricultural production has an impact on the level of providing vital products to the population, and the use of intensive technologies helps to increase the level of agricultural production and increase the volume of vital products. Intensification of agricultural production through the introduction of nanotechnologies can increase the resistance of plants to adverse weather conditions and increase the resistance of animals to infectious diseases and stress. We note the necessity to conduct wider studies to identify the most promising areas of application of nanotechnology as a tool for raising the level of agricultural production.
In assessing the impact of nanotechnologies on the level of food security, it is necessary to assess both the productivity of agricultural production and the quality and safety of the products produced. Regarding the productivity of agricultural production, the existence of numerical experiments in the impact of nanotechnologies on the level of agricultural production reflects the efficiency of the applied technology. The application of nanoparticles as microfertilizer in plant growing contributes to increasing plant resistance to adverse weather conditions and other stress factors, reduces the chemical load on the soil and increases the yield of almost all food and industrial crops. The application of nanotechnologies in livestock breeding contributes to raising the productivity of animals, resistance of animal organisms to infectious diseases and stresses, provides a significant effect on the formation of microclimate in premises for animals and poultry, control of the concentration of harmful substances in the air, disinfection of livestock buildings, electrocontaining of silage mass of green feeds with an electroactivated preservative, treatment of mastitis of animals, decontamination and pasteurization of eggs and egg products, etc. Nanotechnologies are used as catalysts based on nanosized palladium and nanocarbon materials for the hydriding of vegetable oils, as nanoelectronics of grain drying (convective drying together with microwave drying) in the processing of agrarian products. Nanotechnology is widely used in the disinfection of agricultural inputs and production tools in the process of storage of agricultural products.
Thus, the use of nanotechnologies in agricultural production has a positive effect on the production of crop and livestock production, processing and storage of agricultural products, which positively affects the overall level of agricultural production and food security in the country. However, the presence of an uncertain effect of some nanoparticles leads to uncertainty about the impact of nanomaterials on the quality of agricultural production, which necessitates further in-depth research into the properties of nanomaterials and to ensure the regulation, standardization and certification of nanoscale materials used in the processes of production, processing and storage of agricultural products.

A necessary condition for effective functioning of food security is the stability of national currency. The value of the currency has an impact on food prices. The value-reasonable prices is a key prerequisite for economic public access to life-saving food. Many prominent scientists have dedicated their works to the research of the problem. A. Babenko and L. Abramovskiy focus on the need of increase of the money supply. The authors point out that increase in the money supply will intensify the activity of small and medium business, which produces the agricultural products. L. Chernychuk underlines the importance of the impact of currency value on the price level. The author notes that the value of the currency is constantly changing and this affects the general price level in the economy. Existing studies substantiate the presence of an effective mechanism for regulation of the impact of current monetary policy system on food security system. However, the development of economic relations and integration processes of the country in the context of globalization necessitate improvement of the existing mechanism for regulation of the impact of current monetary policy system on food security system.
The article is devoted to assessment of the impact of current monetary policy system on food security system in Ukraine. We analysed the effect of monetary policy on food security system. We have established the impact of monetary policy on public access to food. Monetary policy affects the level of consumer prices by controlling inflation. As a result of correlation and regression analysis we established the existence of a direct relationship between the size of average rates of the money supply and the volume of agricultural production.

The main components of the mechanism of control of funding process of the agricultural enterprises expanded reproduction are considered, the specific elements with the existing conceptual blocks are allocated. An algorithm for optimization of the funding process of agricultural enterprises expanded reproduction is proposed. The following four constitutive blocks of the system are the main components of such algorithm: diagnostics of the financial condition and identification of hidden reserves, financial planning and forecasting, covering of expenses by financial resources, monitoring of the targeted use of funds.
