solation and Compatibility investigation of Phosphate-Solubilizing Rhizosheric Bacteria from Triticum aestivum with Preferred Agrochemicals for Sustainable Agriculture

The study explores the symbiotic relationship between Triticum aestivum and phosphate-solubilizing bacteria (PSB) in the rhizosphere.This research investigated the isolation and characterization of phosphate-solubilizing bacteria (PSB) from the rhizospheric soil of Triticum aestivum (Wheat) plants.Out of 57 isolates, 24 strains exhibited notable P-solubilization, with isolate PD-1 demonstrating the highest solubilization potential at 555.5 ug/ml.The study delves into the plant growth-promoting activities of these isolates, revealing diverse capabilities.Quantitative analyses highlighted the multifaceted potential of isolate PD-8, which not only demonstrated substantial P-solubilization (505.0 ug/ml) but also exhibited remarkable indole acetic acid (IAA) production, reaching 11 ug/ml in the presence of L-tryptophan.Four isolates, including PD-8, demonstrated hydrogen cyanide (HCN) production, with PD-8 further displaying antifungal activity.Compatibility testing with common pesticides showcased the resilience of PD-8, tolerating Carbendazim and Mancozeb up to 100 ppm.However, incompatibility was observed with Metalaxyl-M.These findings position PD-8 as a versatile bioinoculant, offering a comprehensive suite of plant growth-promoting attributes coupled with adaptability to specific pesticides.The study underscores the potential of PD-8 as a promising candidate for integrated agricultural practices, promoting sustainable crop productivity and effective disease management.This research contributes valuable insights into harnessing specific microbial strains for enhanced agricultural sustainability.Bibliography 1.
