Abstract

The objective of the research was to evaluate the effect of crop rotation pattern and multiple cropping systim with non host spesies and reducing bacterial wilt disease incidence in infested soil. Three crop rotation patterns tested were : (red pepper – maize – red pepper), (red pepper – cabbage - red pepper), and (red pepper – shallot – red pepper), the multtiple cropping systems evaluated were : (maize among red pepper), (cabbage among red pepper, and (shallot among red pepper). As supporting data, population R solanacearum after treatments and yield of red pepper were assessed. The results showed that crop rotation pattern such as (red pepper – maize – red pepper), and multiple cropping system (maize among red pepper), prolonged incubation period (9,6 dat) and (9,5 dat), and decreased diosease incidence (48,6 %) and (39,9 %), respectively. Population of the pathogen decreased by (2,4) and (1,1) log cfu/g soil. As the result, yield of the red pepper increased by (44,1 %) and (37,8 %), respectively, compared to the control.
