Microbial abundance in sugar beet rhizosphere inoculated with azotobacter chroococcum
Institute of Field and Vegetable Crops, Novi Sad
Abstract
Rhizosphere appears as the most important niche for microbial activity. It is of direct relevance to nutrient cycling affecting plant nutrition. Rhizosphere can be defined as the root surface and the soil adhering to the root. The aim of this research was to determine the effect of inoculation with Azotobacter chroococcum on the number of microorganisms in the rhizosphere of sugar beet in dependence of fertilization. Field trials were conducted on a chernozem soil at the Rimski Šančevi Experiment Field of the Institute in 2002, 2003 and 2004. The sugar beet hybrid variety Sara was used. Inoculation of sugar beet was performed with a liquid culture of Azotobacter chroococcum strains, which was incorporated into the soil just before planting in the concentration of 109/ml. Differences were registered in population size depending on both the nitrogen dose and fertilisation method. On average, a higher percentage of increase was in the total number of microorganisms (35-118%) than in azotobacter population size (49-52.8%).
