The research was carried out on farms in Kiełpin in Bory Tucholskie Landscape Park in vicinity of Tuchola over 1997-1999. The purpose was to determine of quantitative composition of Pseudomonas and Artrobacter genera, coryneform group and total count of bacteria on roots of potato. Aster cultivar of potato was cultivated in two systems: conventional and ecological. The microbiological analysis showed that the coryneform group dominated over other investigated groups of bacteria. The greatest number of bacteria was isolated from rhizoplane of potatoes cultivated in ecological system. The results obtained during three years of the experiment show that the nmnber of potentially antagonistic bacteria increased along with plant vegetation. The maximum number of these bacteria inhabited roots of older plants
