The influence of a hybrid irradiation system on the growth, development and production process of tomato crops

Relevance. LED sources of plant irradiation, surpassing the level of sodium light sources in terms of energy efficiency, are superior to them in terms of the possibility of optimizing spectral characteristics. Therefore, the issue of wider use of LED light sources when growing plants under light culture conditions is relevant. Possessing significantly greater efficiency compared to high-pressure sodium lamps, LEDs are of great interest to greenhouse growers. However, the successful application of these new light sources requires new approaches. And the main thing is that LED sources of plant irradiation cannot be widely used without changing the technology for growing vegetable crops in protected soil, without introducing new, specially created hybrids. And direct replacement of sodium light sources with LEDs does not make sense.
