Effectiveness of diazotrophs and phospho-mineralizing organisms in maize cropped soil
2002
Timea, H.
The aim of this research was to establish the effectiveness of five strains of Azotobacter chroococcum, five strains of Bacillus megaterium and their combinations with two maize hybrids: PKB-509 and Srecko-5, that were cultivated on fertile soil in two years time period. The yield of maize was measured at the end of each season. The microbiological activity in the soil was also determined including the total number of microorganisms, the number of ammonifiers, oligonitrophilic bacteria, actinomycetes, fungi, azotobacters, phopho-minerilizing and phospho-mobilizing microorganisms, as well as the dehydrogenase activity and the nitrogen content in the rhizosphere and surrounding soil. This research has shown that the selection of Azotobacter chroococcum and Bacillus megaterium must be carried out at the level of plant genotype so that we would be able to choose the most effective strains of bacteria for each maize hybrid. Applying bacterization in maize production, cheeper and ecologically healthier food can be produced.
