Abstract
Pulling of potato vines in Idaho was compared to three chemical vine killing methods for a period of three years. Rolling was examined alone or in combination with chemicals. Effects on yield, grade, specific gravity and stem-end discoloration of the Russet Burbank variety were determined. Rolling increased desiccation overall by 6% but was not a satisfactory vine kill method when used alone. Pulling reduced yields by 14% compared to control plots and 7% compared to sulfuric acid treatments. Specific gravity was reduced overall by 0.002 for all vine killing treatments compared to the control. Pulling and rolling did not affect the amount of stem-end discoloration.
