EFFICACY OF PSEUDOMONAS-AERUGINOSA AND BRADYRHIZOBIUM SP, IN THE CONTROL OF ROOT-ROT DISEASE IN CHICKPEA

Use of growth promoting becterium Pseudomonas aeruginosa, strain Pa-6 and Pa-12 significantly (p < 0.05) reduced the infection of Macrophomi na phaseolina and Rhizoctonia solani on chickpea. P.aeruginosa strain Pa-12 was found effective against F.oxysporum and Pa-6 against F.solan i. Combined use of Bradyrhizobium sp., (TAL 480) and P. aeruginosa sho wed complete control of R.solani and F.oxysporum infection. Use of bra dyrhizobia with P.aeruginosa also showed batter control of F.solani in fection than either used alone. Greater number of nodules per plant we re produced where bradyrhizobia was used with strains of P. aeruginosa as compared to bradyrhizobia used alone.
