A potato seed planting apparatus has: a frame configured to be advanced over a subjacent field into which potato seed is planted; at least one container on the frame for a supply of potato seed; and a plurality of laterally spaced planting units on the frame. Each of the planting units is configured to cause potato seed from the at least one container to be discharged to the subjacent field at controlled time intervals as the potato seed planting apparatus is advanced in a travel path. First and second of the planting units are configured so that the discharge time intervals for potato seeds from the first planting unit are different than the discharge time intervals for potato seeds from the second planting unit with the potato seed planting apparatus advanced at a first speed in the travel path.
