Abstract: The given research is investigated the influences of ionic, ozone, ion-ozone and ion-ozone cavitational treatment on safety of the leguminous plants and oil-bearing crops, such as: peas, chick-pea, colza. During the research, it was revealed that for the leguminous plants, all types of treatment are positive and the processed cultures are preserved for a long time, than the control (non processed) samples. And for oil-bearing crops it is optimum an ionic treatment as ozone is oxidized fats of the oil-bearing crops. The ion-ozone and ion-ozone cavitational technology of grain treatment is used for the purpose of improvement of quality and providing of safety at storage of leguminous plants and oil-bearing crops, taking into account their efficiency.
