The research objective was studying vegetative way of reproduction of Allium. victorialis and Allium ursinumL. and the dependence of the productivity of leaves of two types of ramson on using regulators of growth and microfertilizers. Field experiments were put in medicinal crop rotation of the Department of Botanical Garden FSBN “All-Russia Research Institute of Medicinal and Aromatic Plants” in 2013-2016 by making small allot- ments experiments. The arrangement of allotments was consecutive, the area was 2-4 sq.m, and the frequency was double. The allotments were located on the site of the Department of Agrobiology and Selection of ARRIMAP. The soil of the site was heavy loamy with the contents (per cent for absolutely solid): humus - to 4.31 %; general nitrogen - 0.068-0.072; P2O5 - 0.1; K2O - 2.9-3.5; Al2O3 - 15.0; Na2O - 1.4; MgO - 1.0 %, pH water - 6.1-6.4. The plants of Allium ursinum L. and Allium. victorialis at the age of 5-6 years were pro- cessed by growth regulators twice, starting from the beginning of spring growth with an interval of 14 days. The control was not processed. As a result of pro- cessing of plants of ramson growth regulator "Zircon" with "Siliplant" and "EcoFus" microfertilizers it was pos- sible to note that these preparations had positive effecton the formation of affiliated bulbs and bulbs of re- placement. The share of divided bulbs in Allium ursinumof the preparation "Zircon" after application, together with "EcoFus" microfertilizer made 43 % in comparison with 4 % in control. Allium. victorialis also positively re- acted to application hormonal and micropreparations, but the share of divided bulbs in control option was only 11 % less, than after using the regulator of growth "Zir- con" and Siliplant microfertilizers. Using the regulator of growth "Zircon" together with "Siliplant" and "EcoFus" microfertilizers had positive impact on vegetative repro- duction and efficiency in two types of ramson. For stimu- lation of formation of affiliated bulbs in onions victorious and onions bear use of regulators of growth and microfertilizers is effective. In the plants of onions bear it is possible to increase quantity of affiliated bulbs from 4 % in control to 43 % after use of the regulator of growth zircon together with microfertilizer "Ekofus" (a nutritious concentrate on the basis of alga fucus). Onions victorious the most effective had the use of the regulator of growth "Zircon" and microfertilizer Siliplant (liquid microfertilizer with high content of silicon and micro- cells) - the quantity of affiliated bulbs increased by 11 % in comparison with control. From practical point of view, an important stage of researches is determination of productivity of studied types of onions. Both types of onions form considerable vegetative weight. Growth regulator "Zircon" is successfully used to increase of receiving green material on the plants of Alliaceae fami- ly. Using microfertilizers also positively influences the productivity of plants. At selective crop productivity of leaves averaged for onions bear 0.13 kg/sq.m, onions victorious - 0.29 kg/sq.m. It will be coordinated with increased insistence of onions bear to soil fertility. The onions bear processing by growth regulator "Zircon" together with microfertilizer "EkoFus" had the greatest impact on the productivity of leaves (to 0.16 kg/sq.m), and at onions victorious - use of the regulator of growth "Zircon" with microfertilizer of "Siliplant", is 0.16 kg/sq.m more, than in control option.
