In recent years, many studies in weed science are focused on biology and ecology of weeds. Knowing of weed infestation of agricultural areas is directly dependent on knowing of the time and the dynamics of weed seed germination, as well as the factors which are affecting them. Application of the knowledge about the dynamics of seed banks in soil as well as predicting the time of weed emergence in the models for weed control would enable the reduction of the herbicide use without any influence on the crop yield and level of weed control, with the same or increased economic impact. This paper presents results of testing of seed germination and breaking dormancy of the following weeds: johnsongrass (Sorghum halepense), velvetleaf (Abutilon theophrasti), quackgrass (Agropyron repens) and thorn apple (Datura stramonium). Six different methods of breaking weed dormancy were applied. Method of heating to 80 centigrades showed the best result regarding the breaking dormancy of the investigated weeds.
