| Abstract | The issues of using geobotanical research methods during soil tillage experiments as a complement to herbological methods are revealed. In order to determine the direction of succession in the experimental fields, the classification of vegetation according to the Braun-Blanquet method was used for different tillage systems in a five-field grain-forage rotation (peas – spring barley – spring wheat – soybean – winter wheat). The possibility of using phytoindication to evaluate the processes occurring in agrocenosis of various crops is considered. A significant difference in the number and species composition of the wed component of the agrocenosis was established, which in particular affects the definition of syntaxons of different ranks from class to association. It is proposed to use tillage as an essential factor in the formation of field phytocenoses when characterizing syntaxons. It was established that the studied plant groups belong to the Stellarietea mediae Tx vegetation class. et al. in Tx. 1950 and the order Papaveretalia rhoeadis Hüppe et Hofmeister ex Theurillat et al. 1995. It was found that the degree of weediness after plowing and surface treatment is mostly low, while it is average under No-till system. The data of the phytoindicatieve assessment for winterweed (Stelaria media L.), which occurs quite often in experiments on the following climatic and edaphic factors, are given: thermoregime (Tm), ombroregime (Om), cryoregime (Cr), continentality (Kn), humidity of the environment (Hd), change in humidity (fH), acidity (Rc), trophicity (Tr), carbonation (Ca), nitrogen (Nt), humidity (Gm), aeration (Ae). A significant difference in the number and species composition of the weed component of the agrocenosis was established, which in particular affects the definition of syntaxons of different ranks from class to association. It is proposed to use the types of tillage as an essential factor in the formation of field. | ||
