When growing plants in protected soil, an important factor influencing the formation of quality and yield of crops is irradiation, especially in the seasons when there is not enough sunlight. Therefore, the use of 266 artificial illumination is necessary. Lighting devices that are used in this way must satisfy the conditions for the qualitative growth of the growths and the formation of the crop, while having low energy consumption and corresponding photobiological characteristics. The development of energy-efficient irradiation regimes is one of the promising directions of reducing energy consumption in protected crop protection. The existing state of the problem on the basis of the analysis of publications on bioelectric activity of plants shows the important influence of rhythmic changes on the physiological state of plants, therefore the issue of energy saving during electro-irradiation of vegetable crops can be solved, in particular by pulsed or periodic irradiation of plants in structures of protected soil.
