Abstract: Multifarious plant growth-promoting Bacillus strains recovered from rhizospheric soils
of the Indo Gangetic plains (IGPs) were identified as Bacillus licheniformis MNNITSR2 and Bacillus
velezensis MNNITSR18 based on their biochemical characteristics and 16S rDNA gene analysis. Both
strains exhibited the ability to produce IAA, siderophores, ammonia, lytic enzymes, HCN production,
and phosphate solubilization capability and strongly inhibited the growth of phytopathogens such as
Rhizoctonia solani and Fusariun oxysporum in vitro. In addition, these strains are also able to grow at
a high temperature of 50 C and tolerate up to 10–15% NaCl and 25% PEG 6000. The results of the
pot experiment showed that individual seed inoculation and the coinoculation of multifarious plant
growth promoting (PGP) Bacillus strains (SR2 and SR18) in rice fields significantly enhanced plant
height, root length volume, tiller numbers, dry weight, and yield compared to the untreated control.
This indicates that these strains are potential candidates for use as PGP inoculants/biofertilizers to
increase rice productivity under field conditions for IGPs in Uttar Pradesh, India.2023-04-21T00:00:00Z
