Annotation. This article presents the results of experimental studies on the development of new methods for intensifying plant productivity without the use of chemical methods that lead to poisoning and the threat to human health and life, namely, irradiation with ultraviolet radiation, since ultraviolet exposure concentrates a large number of advantages.

Experiments carried out on seeds of peas and beans showed a positive result, the need for more detailed research in this direction.

Key words: ultraviolet, pre-sowing treatment, seeds, seedlings germination, germination energy.

The article describes the method of use of computer software Mat LAB in the process of educational lessons on the subject " Transition processes " which is one of students studying the direction of formation of the electric power industry in higher education.
