A survey of commercial sugar beet growers in the Red River Valle1 of North Dakota and Minnesota was conducted to determine the change in tonnage and root quality that would occur if sugar beets were flailed rather than topped conventionally at harvest. The data indicated that the growers removed only 20% of the crown material by topping, Which reduced tonnage by 5%.
Removal of all the crown material by hand resulted in a 1.2% increase in sucrose and a 7.1% reduction in nitrate grade. Sugar beet crown material accounted for 20.5o% the tonnage delivered to the factory.
