Evaluating the Phytohormone Proficiencies of Multifarious Bacillus rugosus for Growth Promotion in Arachis hypogaea (L.).

ABSTRACT: The application of Plant Growth-Promoting Rhizobacteria (PGPR) in agriculture is increasingly emphasized as a sustainable alternative to hazardous agrochemicals. This study aimed to isolate and characterize PGPR strains from the rhizospheric soil of Arachis hypogaea L., hypothesizing that the rhizosphere of a healthy plant harbors beneficial microbes with significant plant growth-promoting (PGP) attributes. The isolate AB1 demonstrated promising PGP traits, including phosphate solubilization (56.44 µg mL⁻¹), zinc solubilization (6.1 µg mL⁻¹), ammonia production (3.8 µM µg mL⁻¹), and the synthesis of hydrogen cyanide (HCN) and phytohormones. Objectives included identifying these traits and evaluating their impact on the growth of Arachis hypogaea L. Phytohormonal profiling of AB1 through Ga
