摘要：AbstractIn order to evaluate the impact ofBacillus sonorensison propagation ofAbelmoschus esculentusand its antimicrobial activity was investigated. In the present study,A. esculentuswas cultivated inB. sonorensisinoculated soil and also assessed the morphological as well as biochemical parameters of crops. The culture inoculum ofB. sonorensisinfluenced growth and yield of treated plant. The root (39.5 cm), shoot length (20 cm), chlorophyll (1.06 mg), carotenoid (0.445 mg), protein and total soluble sugar content, NR & starch activity were higher in bioinoculated treated plant than control. The fresh biomass and dry weight were drastically increased in bioinoculated plants when compared to control. Gradual increase in composition of pivotal nutrients (N, P, K) and minor nutrients were observed in the bioinoculated plants. The culture filtrate possessed phytopathogenic activity against different phytopathogens. Among the three different phytopathogens, the maximum zone of inhibition (21 mm) was noticed inAspergillus colletotrichuminfected plants.The fermentation study was carried out in pilot scale fermentor and the synthesis of plant growth promoting substance was found to be 30.00 mg/l IAA.
