Abstract

To investgate growth effect of tomato by Bacillus sp. WRD-1 isolated from soil, the Bacillus sp. WRD-1 cultures were treated into tomato cultivated soil with different dilutions (1:100, 1:300, and 1:500) and autoclaved Bacillus cultures as control. Growth and yeild of tomato enhanced in treatments of the Bacillus cultures compared to control. The populations of native bacteria and actinomyces were increased twice in field treated with Bacillus sp. WRD-1 cultures, but the number of mold was decreased. Since the Bacillus sp. WRD-1 promoted growth of tomato and affected population dynamics of microorganism in field, this strain is prominent candidate as a microbial biocide to improve soil potential.
