Grow 1 plant to yield 5 to 10 potatoes. Yield 10 to 20 pounds per 10-foot row. Space seed potatoes 10 to 14 inches apart in trenches 24 to 34 inches apart.
Yield classes vary from. 4 to 30 for conifers depending on species and site. productivity. A yield class of 20 means that the crop has the. potential to produce 20 m3 per ha per year over a full. rotation. For grant-aided forestry, a site must be capable of. supporting yield class 14 Sitka spruce or yield class 4.
