Yield increases with increasing cropping interval for sugar beet. Yield and yield stability are lowest when sugar beet is cultivated as a preceding crop. Cropping interval of two years seems necessary for high yield stability. Integrating alfalfa enables shorter cropping intervals without yield loss.
