Follow recommended seeding rates, usually about 30,000 plants per acre to maximize yield. Planting early helps extend the grain filling period and reduces the likelihood of stress during pollination. Use a balanced fertility program. While not essential in most of Illinois, starter fertilizer can promote uniform plant emergence for good pollination. Use an effective pest control program.
Scout fields regularly for potential pest problems.
Immediately start first cultivation after last pass with rotary hoe and cultivate two or more times depending on soil condition and degree-days. Propane burners may also be used for small weeds. To avoid excessive mechanical damage to kernels make sure the combine is properly adjusted. Combine and keep border rows separate for use as feed. Field drying is best and allows the kernel to reach full-maturity, but corn may be machine dried at low temperatures .
