Field studies were conducted over a period of three years to compare effects of two row spacings and two plant populations on yields, tuber size, and quality of Norland, Red Pontiac and Kennebec potatoes. The two row spacings were the standard 38 inch rows and a “bed system” where three rows spaced 19 inches apart occupy a relatively flat topped bed that is straddled by tractors and implements. Distance between beds was 38 inches. The two plant populations were planted at 12,900 and 19,300 hills per acre.
Results did not indicate any advantage of the bed system of planting over the conventional spacing. The higher population generally resulted in slightly higher total yields and a greater number of small tubers.
