weed seedbank, actual weed infestation, farming system (ecological, conventional)
Abstract
The aim of this work was to investigate the influence of ecological and conventional farming systems on
weed seedbank and actual weed infestation of winter wheat at agricultural farms Sebechleby, Plavé Vozokany
and Dačov Lom. Significant differences between systems were determined only at the co-operative
Sebechleby where the higher weed seedbank was in ecological system. Higher number of determined weed
species in weed seedstock was in ecological system at Plavé Vozokany and Sebechleby. Dominant weed
species in both systems were Chenopodium album L. and Amaranthus retroflexus L.. Higher degree of actual
weed infestation was determined in ecological system. Characteristics of systems was the occurrence of
perennial species Cirsium arvense and non detection of Amaranthus retroflexus L., weed that had very high
weed seedbank in soil.
