The aim of the study was to evaluate the effect of the placement depth of caryopses as well as of the temperature and pH of
the base on the germination capacity of Bromus secalinus caryopses. Research into injury levels in the cultivation of spring
wheat and winter wheat was conducted. B. secalinus is becoming a serious problem in cereals grown in the minimum tillage
system, particularly in winter wheat. The best and earliest emergence occurred in caryopses of rye brome that lay on the
surface or were placed at a depth of 1.5 cm. The worst emergence was recorded when the caryopses were placed at a depth of
6 cm. The caryopses placed at a depth of 10 cm did not germinate at all. The applied temperature range and the water pH did
not present a significant impact on the percentage of germinated caryopses, low temperatures solely differentiated the speed
of the process. Increased weed infestation of winter and spring wheat significantly affected the deterioration of yieldboosting
parameters of wheat. The weed thresholds of B. secalinus was 3-4 plants for short-straw variety cultivated in worse
soil conditions up to 5-6 plants for the long-straw variety cultivated in good soil conditions.
