The aim of this study was to compare abundance of microorganisms in the rhizosphere of four
different medicinal and aromatic plant species (basil, mint, dill and marigold) grown under
both conventional and organic management. The trials were set up on chernozem soil at
experimental field of Bački Petrovac, Institute of Field and Vegetable Crops, Novi Sad
(northern Serbia). Rhizosphere soil samples were collected in two sampling terms during
2015 (June 2 and July 28, 2015) and analysed by the indirect dilution method followed by
plating of soil suspension on selective nutritive media. The obtained results showed
significant differences in microbial abundance between plant species, growing systems and
sampling terms. The highest number of azotobacters and cellulolytic microorganisms were
obtained in rhizosphere of marigold, while total microbial number and fungi were the most
abundant in rhizosphere of basil. The most common population of ammonifiers, free N-fixing
microorgani...sms and actinomycetes were recorded in rhizosphere of dill. Significantly higher
number of microorganisms was found in organic growing system compared to conventional,
while the number of most tested microbial groups was higher at the first sampling period.
