Numerous studies confirming the effectiveness of the use of the ozone-air mixture in various fields of agricultural production lead to an increase in demand for devices that generate ozone. With the increase in demand, the requirements for these devices also increase. Requirements from customers can be combined in the following series: mobility, ease of operation, ability to smoothly control performance. The solution of these tasks is an important scientific and technical task. This article describes possible options for power supplies for ozone generators, and offers a power supply circuit with the ability to adjust the frequency, the duty cycle and the amplitude of the signal arriving at the discharge gap of the ozonizer. Using this scheme will reduce the mass-size indicators of the ozonizer, thereby increasing its mobility, in addition, it will be possible to accurately regulate its performance and improve efficiency. If necessary, with the help of the proposed scheme, it is possible to introduce the ozone generator into the electric resonance mode, which will allow obtaining the maximum productivity of the ozonator. Thus, the ozonizer, equipped with the proposed power scheme, can be used in various technological processes of the same enterprise

Quality of seed material is defined by several parameters which are: viability, growth force, energy of germination and so on. But one of the most important indicators is productivity. It is possible to increase productivity of agricultural plants when using various ways of preseeding processing. One of ways of preseeding processing is ozonization. Thus, it is possible to receive ozone and air mix by means of various devices. One of the most effective ways of receiving ozone is its synthesis in the field of an electric discharge of an electroozonizer. But, at the moment, in the world the set of designs and modifications of electroozonizers is known. In this regard, we carried out literary search, with the purpose to define the most effective design of the generator of ozone. We investigated various designs of generators of ozone and their positive and negative sides are given. On the basis of the carried-out analysis it is established that the most suitable design for receiving ozone at preseeding processing of seeds is the ozonizer of lamellar type. But, despite efficiency of application of a lamellar ozonizer, it is necessary to achieve its stable work as preseeding processing of especially small seeds demands accurate observance of technological parameters

There are various ways of achieving various crops productivity increase. Here belong the following ways: chemical, physical and physical and chemical. In our opinion, the most perspective way of presowing processing is processing by mix of air and ozone, which belongs to physical and chemical ways of impact on seed material. To obtain the mix of air and ozone is also possible in several ways. The most economically expedient way of ozone synthesis is in the barrier electric ozonizer discharge. However, to achieve a positive effect in ozone influence it is necessary to observe accurately technological parameters as dosages excess can lead to oppression of growth processes in seed. Therefore, it is necessary to consider all known hypotheses connected with ozone influence on agricultural plants and their development process. Researches in this field show that under the influence of ozone on seed material, inside a seed the cleavage of the protein mass takes place. Proteins pass into more available form and as a result it is easier for sprout to receive the nutrients in proteins that promotes the accelerated growth. It is also necessary to note that ozone saturates grain with active forms of oxygen. It is necessary as well to remember bactericidal properties of ozone, which provide destruction of harmful microflora surrounding grain. All these factors lead to improvement of grain sowing qualities and, as a result, increase yielding capacity

Increasing the yield of crops is a global challenge substantiated by the scientists from all over the world. To achieve this goal, there are various ways, one of which is the ozonation of seeds before sowing. This method inhibits harmful microflora, which could be formed on the seed during the period of storage, and excites the chemical processes within the seed that can accelerate the process of growth. But despite the positive effect of ozone-air mixture of seeds and a variety of conducting research there is still no reliable data on the technological parameters of ozone effects on seed crops (e.g., corn). In this regard, we have conducted experimental studies to determine the effective parameters of the ozonation of corn seeds, such as the concentration of ozone in the ozone-air mixture, exposure time and binning after treatment. The influence of these parameters was assessed by changes in growth performance of seed, such as germination, germination and growth of strength. Just at the end of the pilot study we carried out a statistical analysis of the data, which allowed us to estimate the degree of influence of each independent parameter (ozone concentration, exposure time, binning after treatment) for each dependent parameter (germination energy, germination, growth force). The data obtained is presented in the article

The feasibility study on use of ozone and air mix as a preseeding stimulator of growth processes of seeds of corn is presented in the article. The comparative analysis of the standard and offered technologies has been also provided

Increasing the yield of crops is a global challenge posed by the scientists from all over the world. To achieve this goal, we use various methods such as: engineering, agro-technical, agronomic, chemical, physico-chemical and so on. We conducted a theoretical study, which showed that the use of physical and chemical methods of treating seed before sowing has a positive effect on the growth processes of seeds. One of such methods is an ozone treatment, which has established itself as a quality growth stimulator of agricultural plants. But despite numerous studies there is no clear description of the mechanism of ozone effects on seeds. In this article, based on our theoretical study, we have presented a material that allows revealing the positive effects of ozone exposure to the seed. To confirm these theoretical results, we have decided to conduct a pilot study. In connection with what, in this article we have included the materials containing information on laboratory equipment and methods of the experiment. We have also presented measuring equipment and methods of iodine-metric method for determining the concentration of ozone in the ozone-air mixture, exact conformance with calibration gas analyzer which will allow to obtain reliable data on the dose effects of ozone on the grain
