Sweet corn accounts for about 260,000 acres of crops grown in the United States. Sweet corn is a variety of corn with a higher concentration of sugar in the ear. Once planted, sweet corn is usually ready for harvest around 60-100 days. Compared to field corn, sweet corn is harvested earlier at the R3 growth stage, while field corn is harvested at the R6 growth stage when the crop has reached maturity.
A sweet corn crop is very susceptible to nutrient deficiencies which result in loss of crop quality and reduction of overall yield. To maximize quality and yield, sweet corn requires the application of various nutrients throughout the season.
