Population dynamics of Azotobacter chroococcum has been studied in the rhizosphere of a sugarbeet hybrid inoculated with Azotobacter strains 5, 8 and 14. Simultaneously we examined the effects of four levels of nitrogen fertilization (non-fertilized control, 50, 100, 150 and 200 kg N/ha) and the applications of manure and harvest residues. Samples were taken three times in May, July and October. The experiment included inoculated and non-inoculated variants at all four levels of fertilization, in five replicates
