Abstract

Tobacco is the plantation commodity that has a strategic role in national economy, which is a source of State revenues through foreign exchange, customs, taxes, and farmers income sources and can create jobs. Judging from the commercial aspect, these commodities are industrial raw materials in the country, so its presence should be maintained and further improved. Like other plants, one obstacle to increased production of tobacco plants is a bacterial wilt disease caused by Ralstonia solanacearum, which is one of the important diseases in plants. The use of antagonistic microorganisms in controlling plant diseases is one way of controlling the more economical compared to chemical control. Bacillus is one of the antagonistic microorganisms that can be used as a barrier to the growth of R. solanacearum. This study aims to determine the effect of artificial media for bacterial growth and antagonistic effectiveness against R. solanacearum causes wilt disease in tobacco (Nicotiana tabaccum). Hypothesis in this study is expected that the artificial media have an influence on bacterial growth and effectiveness of the antagonists R. solanacearum. This research was carried out in Balittas (Balai Penelitian Tanaman Tembakau dan Serat), on 1 July to 30 August 2009. This kind of research is a real experiment with treatment A (control), treatment B (which had been inoculated tobacco media and ME2 Bacillus and Bacillus isolates BK1), and treatment C (tobacco, which has been inoculated media and TS2 Bacillus, Bacillus isolates BK1). By using a completely randomized design (RAL) 3 times as many tests, each test sample is 5 plants. The parameters observed were plant height measurements were observed every week. Techniques of data analysis is done by testing a single factor analysis of variance followed by Duncan's test of 5%. From the analysis made known that the media affect the growth of antagonistic bacteria. The results showed that the best treatment is the treatment of B (ME2 Bacillus and Bacillus isolates BK1). For the extension was necessary for farmers to use antagonistic microorganisms can be immediately applied, so as not to cause so much damage to their crops.
