Research Interests:
The interaction between Arbuscular Mycorrhizae (AMF) and phosphate-solubilizing bacteria (PSB) is crucial for soil biology and plant nutrition. Arbuscular mycorrhizal fungi (AMF) establish mutualistic relationships with plant roots, facilitating phosphorus absorption, whereas phosphorus-solubilizing bacteria (PSB) convert insoluble phosphorus compounds into forms more accessible to plants. When these bacteria collaborate, they synergistically enhance phosphorus availability and facilitate improved plant growth. This interaction underscores the synergistic functions of AMF and PSB in enhancing nitrogen uptake for plants. Their reciprocal augmentation results in improved phosphorus consumption, enhancing overall plant health and productivity. The study isolates and identifies phosphate-solubilizing bacteria from soil samples, then applies them to rice plants to assess growth, height, chlorophyll content, and yield. It also analyzes root colonization and biochemical effects. The research effectively isolated several phosphate-solubilizing bacteria (PSB) from endophytic and rhizospheric sources, with strains such as Enterobacter Hormaechei (PSB-S8) and Enterobacter Bugandensis (PSB-S13) demonstrating notable growth-promoting characteristics. Rice plants subjected to a combination of mycorrhizal fungus and phosphate-solubilizing bacteria demonstrated enhanced growth and yield, with the BRRI-98 variety achieving the best production. The results indicate that these biofertilizers may function as viable substitutes for chemical fertilizers. The study concludes that phosphate-solubilizing bacteria (PSB) producing indole-3-acetic acid (IAA) are effective biofertilizers for enhancing plant productivity. The combination of Mycorrhizae and Enterobacter Hormaechei treatment for BRRI-98 rice results in higher grain productivity, suggesting that this symbiotic interaction could replace chemical fertilizers in future agricultural practices. Further field trials are recommended
