SPECTRAL ASPECT WHEN USING LIGHT-EMITTING DIODE IRRADIATORS FOR SALAD PLANT CULTIVATION UNDER PHOTOCULTURE CONDITIONS

The authors state that there is currently no alternative to the experimental method of searching for an optimum spectrum of optical radiation to cultivate some plant types. Photobiological research was performed for salad photoculture conditions in a phytothron at the Russian State Agrarian University (RSAU) – Moscow Agrarian Academy (MAA). Irradiators with high pressure sodium lamps (HPSL), and with white and colour (red-dark blue) LEDs were used in the experiment. The obtained results hold out a hope of a decreasing electric energy costs by up to 40–45% when using red-dark blue phyto-irradiators with light emitting diodes to cultivate salad in industrial greenhouses.
