Abstract
In a production experiment in production strawberry plantings in the agricultural cooperative “Gardens of Siberia” (Novosibirsk region) in 2022–2024, the most effective stimulation of the adaptive properties and vegetative propagation of plants under the influence of pre-planting treatment of the root system of seedlings with bacterial strains Bacillus licheniformis VKPM B-10561, B. licheniformis VKPM B-10562, B. licheniformis VKPM B-10563 and B. licheniformis VKPM B-10564 at concentrations of 1×105 CFU/ml was proven. The survival rate of planted plants increased by 13–17 % relative to the control. The number of daughter rosettes in productive plants increased by 33–58 %, to a level of 4.8–5.7 rosettes/plant. The strains B. licheniformis VKPM B-10563 and B. licheniformis VKPM B-10564 had the greatest growth-stimulating and protective effect against fungal infectious diseases. The number of leaves per plant increased by 14–21 %, the biomass of one plant – by 42–48 %, the length of roots – by 10–16 %, relative to the control. Against white leaf spot, fusarium and verticillium wilt, these strains acted with biological efficiency from 41 to 81 %. Stimulation of strawberry yield in all variants with pre-planting treatment with bacterial strains by 0.3–1.0 t/ha was proven. Under the influence of the B. licheniformis strain VKPM B-10561, the yield increased by 35 %, with 2.7 t/ha in the control variant, B. licheniformis VKPM B-10562 – by 16 %, B. licheniformis VKPM B-10563 – by 10 % and B. licheniformis VKPM B-10564 – by 30 %.
