Agronomist Kseniya Davydova has provided clarity on a long-standing question among potato growers: does cutting seed potatoes impact yield? According to Davydova, when seed material is scarce, cutting potatoes into three or four parts is a viable solution, provided each piece has 2-3 strong eyes. This ensures a harvest comparable to that of planting whole potatoes.
Best Practices for Cutting Seed Potatoes
Davydova advises that seed potatoes should be cut just before planting to prevent drying out. The cut surfaces should be dried and dusted with wood ash to protect against rot and disease. She cautions against using small tubers as seed material, as this negatively affects yield.
Optimal Seed Potato Characteristics
The quality of the seed potato plays a significant role in determining yield. Davydova highlights that the best seed potatoes are medium-sized, weighing 60-80 grams, and free of damage. Cutting is recommended only when large seed potatoes are available or when there is a shortage of planting material.

Other Factors Influencing Yield
Davydova emphasizes that potato yield depends on several factors beyond the seed itself, including soil quality, care, and weather conditions. Proper attention to these elements is crucial for achieving a high yield.
The choice between planting cut or whole seed potatoes depends on the availability and size of the seed material. Following best practices, such as ensuring strong eyes and protecting cut surfaces, can help growers achieve optimal yields. Medium-sized, undamaged potatoes remain the best option for planting, but cutting large tubers can be a practical alternative when necessary.
