Abstract

Vermicompost is a rich source of nutrients and beneficial soil bacteria which can promote plant growth in various ways. Ten prevalent bacterial strains were isolated from the cow dung vermicompost and assessed for growth promotion of paddy. Bacterial suspensions (3X108 CFU/ml) were individually applied to the pots planted with paddy variety and vegetative growth parameters and yield were recorded. Among the bacterial treatments, better shoot length, root length and yield were recorded for Bacillus subtilis (VBKT5). Average yield in untreated control plants was less than a half of the yield for B. subtilis (VBKT5) treated plant. This strain was Gram positive, rod shaped, endospore forming bacillus and identified as B. subtilis. The results of the present study clearly indicated that B. subtilis isolated from vermicompost significantly boosted up growth and production of paddy plants and the strain may be explored as a plant growth promoting bacteria (PGPB) for rice improvement.

Keywords: Bacillus subtilis, paddy plant, plant growth, PGPR, vermicompost
