The purpose of the studies was to determine the microorganisms communities in the soil under scorzonera cultivation with the cover crops using. The greatest total CFU of bacteria occurred in the soil from the experimental combination where oat ploughed over in spring or autumn was the cover crops. The smallest total CFU of bacteria was obtained after ploughing over the mulch of tansy phacelia. The use of oats and spring vetch had a positive effect on the population of bacteria from the genera of Bacillus and Pseudomonas. The smallest CFU of fungi was obtained from the soil where oat constituted the mulch. Alternaria alternata, Fusarium oxysporum, F. culmorum, Haematonectria haematococca and Thanatephorus cucumeris were most frequently isolated from the soil. The most isolates of the enumerated fungi were obtained from the soil cultivated in a conventional cultivation and after ploughing over the mulch of tansy phacelia plants. The most antagonistic bacteria and fungi occurred in the soil after ploughing over the mulch of oat, while the least in the conventionally cultivated soil.

Keywords: oat; spring vetch; tansy phacelia; fungi, bacteria
