Have you grown sweet corn each year or field corn? Sweet corn and super sweet corn need warmer weather than field corn, 60-85°F (15 to 30° C.) is best. They need regular irrigation till harvest and about 1 inch (2.5 cm.) of water a week starting about two weeks ahead of silk formation. Other possibilities are nematodes or nutrient deficiencies (see second and last articles for fertilization tips). Nematode control includes crop rotation, cleaning up the area after harvest, and soil solarization.
