Crambe (Crambe abssynica Hoechst) is a winter crop, with high oil content and used as a feedstock for biodiesel production. This study was conducted in 2010 and 2011 at Umuarama County, State Parana, aiming to determine the effects of doses of potassium (0, 15, 30, 60 and 90kgha−1) on grain yield, oil yield, oil content and plant population. This study used four replications of randomized blocks. The increase of K2O levels resulted in higher grain and oil yield per hectare in the first year, but seed oil content and plant population were not influenced.
