The timing of irrigation cessation for potato plants is a critical factor influencing tuber quality and yield. Discontinuing water application at the appropriate stage of development allows the plant to redirect its energy from foliage production to tuber maturation. This cessation is not arbitrary but depends on several observable indicators.
Optimizing tuber dry matter content, skin set, and overall storability are key benefits derived from proper irrigation management at the end of the growing season. Historically, farmers relied on experience and local climate patterns; however, modern agricultural practices incorporate more precise methods based on plant physiology and environmental data to maximize potato harvests.
