Abstract
Use of growth promoting becterium Pseudomonas aeruginosa, strain Pa6 and Pa12 significantly (p <0.05) reduced the infection of Macrophomina phaseolina and Rhizoctonia solani on chickpea. P.aernginasa strain Pa12 was found effective against F.oxyspornm and Pa6 against F.solani. Combined use of Bradyrhizobium sp., (TAL 480) and P.aernginosa showed complete control of R.solani and F.oxyspornm infection. Use of bradyrhizobia with P. aeruginosa also showed better control of F.solani infection than either used alone. Greater number of nodules per plant were produced where bradyrhizobia was used with strains of P. aernginosa as compared to bradyrhizobia used alone.
