Early blight caused by Alternaria solani is a predominant constraint causing major yield losses in tomato. Twenty four isolates of endophytic bacteria were obtained from different plant tissues including root, stem and fresh leaves of tomato plants. The isolates were tested for their antagonistic activity against the causal organism of early blight in tomato, A. solani under in vitro conditions. The isolate EBT22 displayed maximum antifungal activity with an inhibition of 62.66 per cent. The five potential endophytic isolates were further tested for their effect on plant growth parameters of tomato cv. Arka Vikas and the isolate EBT18 recorded highest germination (88.88 per cent), root length (18.67 cm), shoot length (15. 91 cm) and vigour index (3302). The isolate EBT18 recorded minimum PDI of 20.30 per cent when applied as seed treatment + soil drench with a per cent disease reduction of 57.94 compared to control under glass house conditions.
