The dissertation is focused on the findings, whether it is combination of physical and biological seed treatment for selected field crops (oilseed rape, spring barley) comparable with chemical treatment. Evaluated the effectiveness of the physical seed treatment, low temperature plasma (Gliding Arc, microwave), a biological treatment culture mycoparasitic of the fungus Trichoderma virens and culture entomopathogenic fungus Metarhizium anisopliae. In the context of experiments in laboratory conditions, was evaluated the effect of treatment on the evolution grains (the seeds), the percentage of germination grains (the seeds) and the percentage of healthy grains (the seeds). Individual plasma treatment in combination with biological treatment had a significant positive effect on the germination rate of grains (the seeds).There was no negative effect of physical and biological treatments on the grains (seeds). Involved the evaluation of emergence of the treated seed in laboratory and field conditions. In the field conditions for the selected crops in different localities and in different years, was assessed the effect of treatment on the development of the crop health and yield parameters. Plasma and plasma with T. virens treatments positively affected by the model of the plant better integration of crops, the length of the cob, (shell) and yield. The combined adjustment should in oilseed rape positive effect on the faster development of the spring, the length and strength of the root, earlier flowering and ripening. In contrast, the combined adjustment for barley spring positively influenced the emergence and tillering. According to the obtained results it seems that the combined physical and biological seed treatment is an effective alternative to the chemical treatment of seeds.
