Impact of Phosphate Solubilizing Bacteria and Arbuscular Mycorrhiza Inoculation on the Density of PSB, AM Fungal Spore Count, and Root Colonization Percentage in Chilli Rhizosphere Soils

In the rhizosphere soils of chilli var PLR 2, an inoculation experiment involving Glomus fasciculatum and Bacillus megaterium phosphobacteria. A study was carried out to investigate the effects of inoculationonroot colonization, AM fungal spore count, and phosphobacterial population at varying phosphorus levels. Plants that were inoculated with Bacillus megaterium and G. fasciculatum showed greater values than plants that were not infected in all treatments. The rhizosphere soil had the highest root colonization percentage (84.32) and AM fungal spore quantity (127, 109 spores per 100 g of soil) at a 75% phosphorus level, which was followed by a 50% phosphorus level (73.40, 126.00 spores per 100 g of soil), respectively. The maximum phosphobacterial content was obtained by co-inoculating G. fasciculatum and B. megaterium at a phosphorus level of 75%.
