The aim of this study was to determine the microbiological activity in soil under beans in organic and conventional production. Organic production was conducted on the field in the village Pivnice (Serbia), while conventional production was conducted in the village Curug (Serbia) during 2014 on the chernosem type soil. Cultivars of beans Belko, Dvadesetica, Maksa, Slavonac, Sremac, Zlatko were used. Before sowing, the bean seeds were inoculated by biofertilizers NS-Nitragin. NS-Nitragin contains a mixture of selected strains of symbiotic bacteria Rhizobium leguminosarum bv. phaseoli. The total number of actinomycetes, ammonifiers, Azotobacter, bacteria and fungi were determined. At the end of vegetation period in conventional production the highest number of actinomycetes (5.83) and fungi (4.87) was recorded in cultivar Dvadesetica. In organic production the highest number of ammonifires was in cultivar Sremac (9.91). The highest number of bacteria was in cultivar Dvadesetica (9.08) and the highest number of fungi was in cultivar Zlatko (5.14). The results have shown that number of microorganisms was higher in organic production.
