- Depending on the size of the area planted, irrigation or watering is necessary for maximum corn production. Applying water to the corn crop in a scheduled manner proves to be the best method---rather than waiting for the plants to show signs of dryness. Devices that measure soil moisture and methods that check the amount of incoming and outgoing water will help determine the irrigation schedule.
- The soil needs to be prepared to prevent wind and water erosion. All weeds should be removed. Compacted or hard ground needs to be turned by hand or plowed to loosen. To retain as much moisture in the soil as possible, it is advisable not to work the land too hard. Corn rows of 36 inches are recommended for maximum production.

Hybrids differ in resistance to disease, maturity, crop yield, quality and geographic adaptability. Consider the characteristics of the farm or garden when selecting the hybrid. The companies that sell the hybrids generally recommend the best production method for each hybrid.
- Corn planted earlier in the season is proven to outproduce that planted later into the summer. In south Georgia, early corn is planted starting in the middle of March and in the middle of May in north Georgia. Dryer periods and hotter temperatures during corn pollination are avoided by planting corn early.
- The infertile and acidic Georgia soil needs large quantities of fertilizer and limestone. Fertilization amounts are based on the desired crop yield and use. The best way to determine how much to fertilize is to test the soil in the fall. It is best to keep the fertilizer away from the germinating seed.
- According to the National Gardening Association, corn can be planted in double rows to save space. Double corn rows need more fertilizer, are easier to irrigate and increase the odds of pollination. The association defines a double as two rows planted 8 to 10 inches apart.
