For best results, sweet corn seed should be planted after the soil temperature has reached 60*F. In most parts of High sugar type corn, while lacking the creamy texture and flavor of the standard and sugary enhanced corn, is commercially attractive due to it higher sugar level and the fact that conversion of sugars to starch is slower than other corn types or is incomplete. Thus, super sweet corn will remain sweeter much longer than other corn type sand its crisp kernels hold up much better when mechanically harvested.
The high sugar types of sweet corn are more difficult to grow than standard corn. Seed germination percentages of super sweet types may be reduced, particularly under cold soil conditions. Weather in Kentucky can be unpredictable, so at present, use of standard varieties for very early plantings intended for early markets is encouraged. High sugar corn is also generally more attractive to insects, birds, groundhogs and raccoons and is more susceptible to heat and drought stress than standard sweet corn. Irrigation is essential to ensure high quality in the high sugar corn types. Soil analysis tests are recommended to determine needs for phosphorus, potassium and/or nitrogen amendments.Effective pest control is particularly important because the product ends up on the tables of the public
