Title

Isolation of Indole Acetic Acid Producing Bacteria from Fig fruit decomposed soils and Their effect on plant growth promotion

Abstract

Production of growth hormones has been the major criteria of bacteria in plant growth promotion. Indole acetic acid (IAA) production is a major property of rhizosphere bacteria that stimulate and facilitate plant growth. Indole acetic acid (IAA) is one of the most important phytohormones enhances the root structure and plant growth. The present work deals with to isolate the bacteria having Indole Acetic Acid (IAA) producing activity from soil under fig fruit waste decomposed soils. Isolates were characterized on the basis of staining techniques and biochemical tests such as oxidase, catalase, indole, TSI, methyl red, Voges – Proskauer, citrate utilization, urease and starch hydrolysis test. The bacterial strains were screened for their IAA production, the major growth promoting trait helpful for the sustainable agriculture. IAA production from different bacterial strains was estimated using Salkowski reagent Out of sixteen isolated bacteria five isolates were selected as efficient producers of Indole acetic acid. All five isolates were observed for the production of IAA, among them FFA16 isolate was comparatively recorded with high competence. All the isolates were observed for their effect on maize and paddy seeds plant growth and found increased plant growth with the isolates when compared to control. In conclusion the study suggests the IAA producing bacteria as efficient bio fertilizer inoculants to promote plant growth.
