Abstract
In trials in 1964-7, potatoes planted in early spring when the sowing of cereals started and harvested 2 weeks after most of the plants had produced flowers gave the highest yields of best quality seed tubers; yields and quality decreased with delay in planting. The high quality of seed tubers produced in this way resulted in increased yields in the following 2-3 years. The planting of potatoes in summer for seed production improved seed tuber quality only in the years favourable to growth.
