Abstract


Microbial groups developed in the rhizosphere ensure the stability and dynamics of nutrient transfer processes to plants. Additional soil inoculation with rhizospheric bacteria acts to expand the ecological niche, supplements the activity, the number of individuals and promote plant growth. In today’s agriculture, there is a need for the usage of rhizosphere microflora and integrative approaches to stimulate plant growth. The aim of the study is to evaluate the use of biofertilizers as starter stimulators in autumn wheat. Different concentrations of Bactofil, containing rhizospheric bacteria, were applied in small rhizothrones. Evaluation of relationships between bacterial inoculum and plant reveals the degree of applicability and adaptation to the soil conditions of exogenous microflora. Doses of 15.6 x 108 and 20.8 x 108 cells/m2 stimulates the root elongation and higher level of mycorrhization. Bioproducts can be viable solutions to stimulate the initial development of wheat plants.
