Evaluation of the compatibility between native rhizobacteria isolates

Abstract

Compatibility between the Plant Growth Promoting Rhizobacteria (PGPR) microbes to colonize the root system without inhibiting each other is a pre-requisite for successful benefit of using multiple microbes in a crop field. Taking this into account, the present investigation was conducted to test the compatibility between different native rhizobacterial isolates in-vitro in the Plant Bacteriological Laboratory, Department of Plant Pathology, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal during 2021- 22. All the efficient and native rhizobacterial isolates tested were compatible with each other under in-vitro conditions except BRB 88 and BRB 89, BRB 35, BRB 42, BRB 52, PR 19; BRB 89 and BRB 35, SM 9, SM 14; BRB 35 and PR 19; BRB 42 and PR 18; BRB 52 and SM 9; CK2LPP and CK2LP12, GP2, GP8, G11SP37, K11SP4, SS2LP; CK2LP12 and GP2; GP8 and K11SP4; SS2PLP and SS2PP; GP2 and G1SP37, SS2PP; G11SP37 and K11SP4; SS2PP and S21SP14; BRB 88 and CK2LPP, GP2; PR 16 and SS2PP, S21SP14; PR 20 and GP8; BRB 52 and CK2LPP, CK2LP8, GP2, GP8; BRB 56 and GP2, GP8; SM 9 and CK2LPP, CK2LP8, CK2LP12, G11SP37.
