Summary: The allelopathic impact of 23 perennial weed species on oilseed radish by petri dish and soil bioassays was studied. Weed extracts were prepared at concentrations of 0.25, 0.5, 1.0, 2.0, 4.0, 8.0 and 16.0%. The influence of the weed extract on germination and seedling growth of oilseed radish was analyzed according to several germination indexes. The
"speed of germination", "coefficient of the velocity of germination" and the resulting levels of allelopathic potential in terms of seed germination (APG) were used to assess the allelopathic effect of the researched weed species. The application of indicators allowed determining the specific features of the influence of extracts of perennial weeds on the duration of the germination period, the effects of germination delay and the general prolongation of the period of formation of similar seeds with typification on classification groups. Conducted daily surveys for the calculation of these indices allowed to obtain a graphical interpretation of the reaction of the seeds of the test object to the extract of each weed species. This allowed identifying species of weeds for which the use of oilseed radish in the system of its biological control will be effective.
