The paper evaluates Printheads the effect of fallowing on seasonal and multiyear dynamics, as well as on the spatial structure of Tussilago farfara population.In four years turfing and rapid increase in the size of grass populations - those of Agropyron repens (L.) PB.and Dactylis glomerata caused the elimination of Tussilago farfara population.The studies have showed that a decrease in the population size resulted from hampering of both vegetative and generative reproduction.

The interspecific competition for available space seems to be a crucial factor limiting emergence of new shoots.In the agrocoenose big population size of Tussilago farfara remained Upper Spray Arm Shaft throughout the studies.
