Traditional technology of growing of lettuce sowing requires perfection and development of the new technological measures sent to the valuable use of biological potential of sorts. One of factors of increase of level of the productivity there is the use of microfertilizers. Purpoze. To investigate influence of treatment the microfertilizer of Bifoliar Mikro-plant on forming of food organs of lettuce sowing. Methods – the field, laboratory, statistical. Researches were conducted in 2016-2017 on cespititious-middling опідзолених soils of north part of Forest-steppe of Ukraine in NDP the «Fruit and vegetable garden» in NUBiP of Ukraine on the collection area of department of vegetable-growing. Sorts were studied in researches - Аficion, Коnkord, Vinteks, Gogen, Аkvinj and microfertilizer of Bifoliar Mikro-plant. Foliar nutrition on vegetans plants conducted a microfertilizer twice - in the phase of one or two true leaves and sockets of leaves (7-8 leaves) in a dose 0,5 l/ha. Results our research finish telling, bringing of Bifoliar Mikro-plant in a dose 0,5 l/ha provide the increase of the productivity of lettuce sowing on 3,2 - 6,9 t/ha depending on a sort.
