Abstract

Three strains of rhizobacteria, namely Azospirillium brasilense, Azotobacter chroococcum and Klebsilense pneumoneae and commercial product HALEX were tested for growth promotion  of chickpea plants and for controlling Fusarium oxysporum f. sp < em>. ciceris the causal   agent  of fusarium wilt disease. In vitro, the rhizobacteria reduced the dry weight of mycelium of fusarium by 47.3-70.7%, and highest suppression was achieved by K. pneumoneae and the three mixture isolates. In-vivo significant decrease in disease severity was observed when chickpea seeds were coated with HALEX.This treatment also, increased  fresh and dry weight /10 plants. Dry weight increased from 61.18, 26.19 to 79.43, 56.13 g in soil nontreated with the pathogen and from 38.49, 21.06 to 45.61, 27.13g in soil treated with pathogen on cv. PV 60 and cv. JG 62 respectively. Also, significant increases were observed in the number of seeds /100 pod and weight of 100 seeds. Weight of 100 seeds increased from 24.008, 9.59 to 28.73, 10.29 g in soil nontreated with the pathogen and from 17.91, 7.54 to 23.30, 10.007 g in soil treated with the pathogen on cv. PV 60 and cv. JG 62 respectively.
