The Average Potato Yield Per Plant

Potatoes are a cool-season crop that is fairly easy to grow in a home garden. Many varieties of potato are available, and they can be stored up to six months or more after harvest.

Potato plants are grown from "tubers," which are pieces of seed potatoes. Each seed piece is about the size of an egg. A pound of seed potatoes will typically produce six to eight tubers.

Spacing of plants will influence size and yield of potatoes per plant. Ideally, tubers should be planted 3 to 4 inches deep and 6 to 8 inches apart, in rows that are 36 inches apart. A 100-foot long row planted this way will produce approximately 150 to 300 pounds of potatoes.

Each potato plant in a row will generally produce 3 to 5 lbs. of potatoes. Fluctuating temperatures, soil moisture and nitrogen levels in the soil can all influence yield.
