Biotic Stress as Induced by Ralstonia solanacearum on Groundnut Varieties (Arachis hypogaea. L)

Ralstonia solanacearum is a destructive soil borne groundnut (Arachis hypogaea. L) pathogen. It causes reduction in groundnut production to at least 10%. In less affected field, 10%-30% groundnut plants show symptoms, causing more than 20% yield reduction. The experiment was arranged in Randomized Complete Block Design (RCBD) with three replications. The treatments include, seed inoculation, and stem injection, foliar spray and control. The result showed that there is significant differences (P<0.05) for number of pod per plant at harvest between varieties, but there is no significant differences (P>0.05) between treatment and treatment by interaction. There is significance difference (P<0.05) between varieties for number of seed per plant at harvest, but there is no significant difference (P>0.05) between treatment and treatment by variety interaction. The result for seed weight after harvest showed significant differences (P<0.05) between variety and treatment by variety interaction, but there is no significant differences (P>0.05) between treatment.
