A method was developed to allow nondestructive growth measurements of potato tubers (Solanum tuberosum L.). The technique, consisting of 2 basic components, is simple and effective for observing tuber growth from initiation through maturity. The first component is a “double-pot”, which facilitates washing the growth medium from the tubers. The other component filters the growth medium from the wash water for retrieval and reuse of the medium. Any number of double pots can be used, but only one filtering system is necessary. After observations and measurements have been made, the growth medium can be replaced with little disturbance to the tubers. We generally take tuber growth measurements at 2-week intervals, but we have uncovered tubers at less than one-week intervals without any visible damage.
