Growth Promotion of Plant by Nutrient Mobilizing PGPR of Salt-Affected Soil

Plant growth promoting rhizobacteria (PGPR) are a group of beneficial bacteria that are associated with ischolar_mains of plants and their rhizosphere. Most of the PGPR have been known for N₂ fixation, IAA Production, Phosphate-solubilisation and Siderophore production. This study was conducted with nine isolates of Azotobacter, isolated from salt affected soil. The observation were made on T₁ (Control), T₂ (N_1/2P_1/2K + KBH_12A) and T₃ (N_1/2P_1/2K + mixed culture of KBH_12A, KBH_18A, KBA_2A, KBA_13A, MMA_3A, MMA_14B, MMA_19B, MBA_8A, and MBA_20B). The experiments on rice were carried in Randomized Block Design (RBD) with three replication. In the present investigation an attempt has been made to ascertain the effect of PGPR in different plant parameter such as impact on shoot and ischolar_main length, impact on number of tillers and ischolar_main and impact on flowering.
