ABSTRACT
The rizhospheric bacteria improve plant growth and development as well as impart tolerance against biotic and abiotic stress. Chickpea is vital source for protein in developing countries and called poor’s men’s meat, but it productivity is hampered by wilt diseases caused by Fusarium oxysporum f. sp. ciceris (Foc). The rizhospheric bacteria potentially act as biocontrol agent where it helps to reduce environmental pollution caused due to use of chemical control measures. In present study Bacillus subtilis isolate K18 (BS-K18) found effective antagonist against wilt pathogen Foc under in vitro condition was evaluated under laboratory study. The BS-K18 seed treatment effectively reduced the onset of disease symptoms in susceptible genotype JG-62 up to 7 days after transplanting in Foc sick soil. Apart from improving disease tolerance the BS-K18 showed PGPR effect on both resistance and susceptible genotype where shoot length, root length, number of root plant-1, fresh weight and root volume were significantly improved as compare to control chickpea genotypes. These promising antagonist isolates, BS-K18 with PGPR activities could be further evaluated in field study for its commercial exploitation.
