Small-scale production can be sold directly on the farm or at roadside stands, farmer s markets, or local stores. Large-scale production requires a considerable investment in harvesting equipment and packing and hydrocooling facilities to prepare shipments to terminal markets or supermarket distribution centers.
Sweet corn is a warm season crop, easily killed by frost.
It is subject to serious injury if exposed to prolonged cool temperatures of several degrees above freezing. Growing conditions in central Oklahoma provide about a six week harvest period beginning in early June and ending in mid-July. High temperatures, which normally occur in early July, interfere with pollination and prevent season-long production. Corn earworm is a serious insect pest, and sweet corn production should not be attempted without an adequate insecticide spray program during the silking to harvest stages of crop development. Site and Soils Sweet corn grows on a wide range of well-drained sites and soils.
