Abstract:

Plant growth-promoting rhizobacteria (PGPR) are used as alternatives to the chemical fertilizers to increase crop yield in agriculture. The present study was undertaken to isolate, screen and evaluate selected promising PGPR isolates from maize fields. Out of 30 bacterial isolates, four most promising isolates (SP-01 to SP-04) have analysed for the various PGP traits. Bacterial isolate SP-03 showed the maximum PGP traits like N2 fixation, IAA production, ammonia production and siderophore production in in-vitro condition. To identify the isolates morphological and biochemical tests were performed and analysed in the ABIS online biochemical identification system. These analysis confirmed isolates belonged to Brevibacillus sp. and Panibacillus sp. As per our knowledge, the present study one among the few studies of Brevibacillus and Panibacillus sp. which exhibit various PGP traits.


Keywords: PGPR, N2 Fixation, Ammonia production, IAA, Siderophore and AIBS
