Inter-row subsoiling increases marketable yield in potatoes

Kurzfassung

Inter-row subsoiling increased average yield of 40-65 mm potatoes by 14 pct during 2001-2003. But there were significant differences between the years. In 2001, the yield increased by 49 pct, whereas it was unaffected or decreased in 2002 and 2003. Better understanding of optimal subsoiling conditions is needed to exploit the benefit of inter-row subsoiling.
