No Evidence Sowing Date Influences Optimum Plant Density of Sweet Corn Grown in the Midwestern United States

Sweet corn ( Zea mays L.var. rugosa or saccharata ) is sown across a wide range of dates to provide steady supply marketable ears for fresh market and processing. There perception in the sweet industry that plant density tolerance declines late-season plantings midwestern United States; however, publicly available data support this cannot be found. Using field experiments, objectives research were quantify effect sowing date on growth responses determine extent which influences optimum maximum yield/profit. few main effects interactions crop growth. More importantly, there was no economically optimized yield. Although variations exist densities States, these are likely driven by several factors other than have not yet been fully characterized.
