To determine the impacts of cultivating soil rapeseed (Brassica napus L.) as displacement plantation on soil fertility, the field experiments were conducted. Cultivation of the rapeseed (Brassica napus L.) is 9.3-10.3 center/ha which has been increased by 2.7-3.0 center/ha compared to the previous ones after cultivating fallow and leguminous. The study found out after replanting the rapeseed afterwards fallow and corn, the hummus was increased by 0.10-0.51% from other alternatives.Therefore planting rapeseed after planting fallow- wheat-rapeseed-corn as alternations increases the intensity of soil fiber growth by 10.0-37.07% or 0.005-0.02 mg / per day. Yield of rapeseed grain and its biometric indicators: the rapeseed is compounded more by composite fertilizers (N26P18) for 30 kg / ha compared to control version and other dose alternatives.
