The use of chemical fertilizers to the crops is very serious issue which has adverse effects on the soil quality and also the environment. The biological approach must be used for the plant growth promotion. The actinomycetes were isolated from the rhizosphere soil samples of maize from Dhule district and College of Agriculture, Pune, India. The isolates were studied for plant growth promoting traits viz., chitinase activity, phosphate solubilisation, indole acetic acid production and antifungal activity. The effect of actinomycetes and also with addition of chitin was studied on the plant growth. The isolates showed chitinolytic activity and phosphate solubilisation. Antifungal activity was shown by two isolates against the fungal phytopathogens. The chitinolytic actinomycetes also showed increase in the growth of plants viz., maize, wheat and bajra. The study shows that actinomycetes can be used for the enhancement of growth of different plants and as strong biological control agents.
