Abstract:The effects of potato plant density on yield quantity and quality were investigated at the Hankkija Plant Breeding Institute from 1971-73, using seed rates of 1600, 3200 and 4800 kg/ha, and seed sizes of 40, 80 and 120 g. The varieties used were Ijsselster and Record. The number of stems per m2 rose with increasing seed rate and with increasing seed size. Stem number increased with seed rate faster for small seed than for large. The response in stem number was greater for Ijsselster than for Record. The number… Show more
