METHOD OF GROWING LETTUCE Russian patent published in 2024 - IPC A01G22/15 A01G7/04 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, in particular to protected ground vegetable growing. In the method, lettuce seeds are sown in mineral wool cubes with volume of 64 cm³ and grown under hydroponic conditions for 35 days at a daytime temperature of +25 °C, at night +23 °C, photoperiod of 18 hours. During the entire vegetation period, plants are irradiated with light with a spectral composition having emission maxima in the blue part in region of 455 nm, in the red part – 655 nm, adding to the spectrum a band of far red light in region of 735 nm, with a photon flux density at level of 5 cm from the surface of a cube of mineral wool of 160 mcmol⋅m^-2⋅s^-1.

EFFECT: method provides higher nutritional value of products due to intensification of biosynthesis of biologically active substances – anthocyanins in biomass of grown plants.
