Summary Experiments carried out on seed size and spacing forRecord potatoes in 76 cm rows showed that, for all seed sizes chosen, increasing seed population above 29640 tubers/ha gave only
small increases in both total and ware yield. A further series on row widths indicated that row widths can differ quite considerably
without giving any consistent differences in ware yield. 相似文献
