PURPOSE: To increase the yield of potato in high efficiency by scattering a non-phytohormoal plant growth regulation agent to the leaf and stalk of a potato plant in the flowering stage, etc. CONSTITUTION: The yield of potato can be increased by applying a non- phytohormoal plant growth regulation agent such as a triazole compound e.g. (E)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1,2,4-triazol-1-yl)-1-penten-3-ol (salt) or an isonicotinanilide compound e.g. 4'-chloro-2'-(α)-hydroxybenzyl)isonicotinanilide (salt) to the leaf or stalk of a potato plant in the flowering stage or the tuberous root fattening stage.
