Plant growth promoting is a multitask phenomenon. The bacteria achieve this by suppressing plant pathogens, production of plant-growth regulators, fixing atmospheric nitrogen, and solubilizing phosphate and micronutrients. Therefore, the present study aimed to examine the facultative oligotrophic bacteria isolates as biocontrol and plant growth promoting agents. The test isolates (FNS1 and FNS2) possessed Plant Growth Promoting Rhizobacteria (PGPR) (abilities including Indole Acetic Acid (IAA) production, Salicylic acid (SA) production, zinc and phosphate solubilization, N2-fixation, cellulase and chitinase production) and potency against pathogenic fungi causing damping-off disease (Pythium ultimum and Rhizoctonia solani). Isolates were tested against high temperature, pH and salt tolerant characters which prevail i.. View More»
