Descriptif
The aim of the present research is to isolate and characterize the rhizobial strains from wild and medicinal legumes. It would be interesting to know about the plant growth promotory ability of rhizobia from wild medicinal legumes for growth enhancement of agricultural crops. The root nodulating bacteria were characterized morphologically, physiologically and biochemically to recognize their taxonomic position. Unfortunately as far as tropical regions are concerned very less (only 15%) research regarding the taxonomic studies of rhizobia-legume relationship has been carried out so far (Elkan, 1992). Nodule formation ability of r · zobja in different leguminous plants and interaction ability of rhizobia with other microbes will also be carried out. In addition, monitoring the persistence of selected inocula in soil condition and to understa.I)d the mechanisms involved in the interaction of rhizobia with other microbes present in the soil will be done. Interaction of Pseudomonas and Rhizobium were checked in vitro and in vivo to be usedL consortial inoculu.R’tS7 Further, effects of monoinoculation as well as coinoculation of Rhizobium and Pseudomonas were examined in vitro and in vivo. Finally, the aim of the study was to produce the suitable bioinoculants of the selected rhizobial strain with rhizopheric plant growth promoting rhizobacteria (Pseudomonas) having biocontrol activity and their impact on host plant productivity so as to reduce the load of chemical fertilizers and pestisides.
