The increase in crop food production is directly related to the increase in crop yields. Higher yields depend on many factors, including seed germination of a specific crop. Pre-sowing seed treatment is one of the ways to increase seed germination. Ozone treatment of seeds is an environmentally friendly and cost-effective technique. The method belongs to the physical methods of pre-sowing treatment. Ozone treatment of seeds requires a rationale for the treatment modes and safety provisions. To

... rovide the rationale a machine for the ozone treatment of seeds was developed. The machine is patented as a utility model. The paper provides a description of the machine design and operation. The experiment has resulted in timing the reduction of the ozone concentration in the ozone treatment chamber to the MAC level when air is forced by the fan. The corresponding regression equations were deduced and the proportionality coefficient for the previously obtained theoretical dependence was found. They help time the reduction of the ozone concentration to the MAC level depending on the initial concentration of ozone in the seed treatment chamber, the chamber capacity, and the fan performance. With the right timing, experimental studies on justifying ozone treatment modes in various crops can be safely conducted. The timing was successfully used to justify an ozone treatment mode for marrow squash seeds. The experiment was conducted without damage to the personnel's health.
