Methods of regulation the occurrence thaliana violet (Viola arvensis Murray) on arable land
 MACHÁČEK, Václav
Due to repetitive planting of certain crops in the crop rotation process, there came to be a loss of certain weed species on the cultivated land, but because of this, a small selected number of species, because of there frequency and abundance, played an import role in the cultivated soil, (or harvest). Currently one of these weed species is the violet thaliana, which occurs in all cultivated crops, especially cereals and oilseeds. The significance of this harmful average weed is increasing significantly. Therefore an attempt was established on the farm, DZV Nova Bystrice. The aim of this experiment is to regulate thaliana violet (Viola arvensis Murray) on arable land.
