Farmers and agronomists have developed many new varieties and sub-varieties to fit different soils and climates.<ref> see [http://www.umaine.edu/paa/PVI.htm for a listing]</ref>  Harvest is usually midsummer to late fall. Most farmers plant in early spring, using well-drained, slightly acid soil; they avoid wet, soggy soils.<ref> See [http://www.ag.ndsu.edu/pubs/plantsci/rowcrops/pp877w.htm Gary A.
