Title

PLANT GROWTH PROMOTING POTENTIAL AND DIVERSITY OF BACTERIA FROM RICE RHIZOSPHERE OF SALINE SOIL

Abstract

Bacteria including PGPR plays a very important role in plant growth promotion and increase yield of crops. Most of the bacteria produce phytohormones, fixes atmospheric nitrogen, solublizes the phosphates and resist phytopathogens by production of siderophores. An understanding of microbial diversity perspectives in agricultural contest, is important and useful to know soil quality and also helpful for taking measures for soil management and increased plant productivity. It is also important to understand the relationship of soil and plants with the diversity of associated bacteria for their better exploitation. Therefore, it is important to know the microflora and their diversity. Most of the rhizospheric bacterial diversity from normal soil have been studied and organisms have been explored for their use as bioinoculents. However, saline soil rhizospheric microflora remain unexplored. By considering this, in the present study a total of sixty two bacterial isolates including PGPR have been isolated from rice rhizosphere of saline soil of Kolhapur district of southern Maharashtra, India. Isolates were identified up to genus and species level. All the isolates were studied for their nitrogen fixing ability, phosphate solublizing activity, Indole acetic acid production and Siderophore production at higher salt (NaCl) concentrations1%, 2%,3%,up to 15%. .Results indicated that all the isolates grows up to 7 % NaCl concentrations, showed optimum activities at 4% NaCl concentration and tolerated 10% NaCl for 12 hours. Of all 62 isolates 21 produced Indole-3-acetic acid (IAA) 29 solublized phosphates, 21 fixed atmospheric nitrogen, and 10 produced Siderophores and 4 have not showed any plant growth promoting activity. All the isolates were identified up to genus level and most of them up to species level using Bergeys manual of systematic bacteriology, and MICRO IS software. Amongst all the genera identified Pseudomonas was found to be dominant followed by Bacillus. Present study showed that amongst nitrogen fixing bacteria Azotobacter spp., found to be most dominant and Pseudomonas was found to be most dominant phosphate solublizer. Study indicated the importance of these organism as bioinoculents for saline soil and can be explored for biofertilizer production.
