Importance of PGPR application and its effect on microbial activity in maize rhizosphere
Institute of Field and Vegetable Crops, Novi Sad
Improvement of Maize and Sorghum Production Under Stress Conditions (MESTD - 31073)

Microorganisms are involved in the formation of soil fertility, both potential and effective. They facilitate the processes of humification and dehumification and play a key role in the cycling of nutrients - macro and microelements. Rhizosphere is the soil in direct contact with plant roots and influenced by plant exudates. Root exudates of maize significantly affect the composition and abundance of microorganisms in the rhizosphere. Bio-fertilizers are microbial fertilizers composed of highly effective strains of bacteria, algae and fungi isolated from soil. Their application activates microbial processes that secure a better and steadier supply of plants with nitrogen, phosphorus, potassium and some micronutrients. The application of PGPR-containing biofertilizers reduces the need for expensive nitrogen fertilizers, facilitates phosphorus uptake by plants and affects the direction and dynamics of microbial processes.
