DIVERSITY OF ROOT BACTERIA FROM TOBACCO CROPPING SYSTEMS
Abstract Little is known of the effects of various cropping systems on the rhizobacteria associated with tobacco. Our objective was to develop a database on the rhizobacteria present in continuous and rotational fields of tobacco by sampling in field plots over a 4-year period. Plots were established in a Norfolk soil near Florence, SC. For continuous culture plots, tobacco was planted in monoculture for four years. In rotational plots, tobacco, soybean, corn, and tobacco were planted during the 4-year test. Rhizobacteria were isolated from the roots of tobacco and rotation plants and identified by fatty acids composition using gas chromatography (GC/FAME). Arthrobacter and Bacillus were the primary genera recovered from non-rhizosphere soils. Four to seven genera of rhizobacteria accounted for the predominant organisms in both cropping systems; the total number of genera ranged from 17 to 22. Under monoculture tobacco, gram-negative rhizobacteria were dominant in July, whereas, gram-positive root bacteri...
