They say a 1:7 ratio is a good harvest. Plant 10 pounds seed potatoes, harvest 70 pounds. I have been planting Russet as well as Yukon Gold and have attained a 1:10 ratio. planted 10 pounds harvest 100 pounds. Some of my russets go well over a pound. I sprinkle a 12-12-12 fertilizer in the planting furrow and mix it into the soil. Keep the plants well watered. About midway through the summer I topdress with compost. Good Luck with your spuds.
