Technical and economic efficiency of led lights in green crops

Keywords: LED phyto-lights, effective phyto-lighting, closed ground, lettuce yield.


Year-round provision of fresh vegetables and green products to the population of Russian regions of 1 and 2 light zones remains an important social and economic task, despite the modern devel-opment of logistics. The need to provide fresh crop production in the context of the COVID-19 pandemic has increased. Agro-industrial greenhouses still rely mainly on traditional light sources. The purpose of this scientific study was therefore to assess the effectiveness of modern LED lights in finishing salad plants in a closed ground relative to traditional sodium light sources. The scientific hypothesis of the research carried out was a thesis about the possible effectiveness of light-emitting diode phytoplants with peak values of red (660nm) and blue (440nm) light spec-trum in comparison with traditional sodium light in artificial finishing of vegetables of protected soil. The study revealed the production, commercial and energy efficiency of salad plants from the plant lamps tested. The study resulted in practical recommendations for producers and further research on the subject.
