As far as gardening is concerned, the main difference between hybrid corn and any other variety is the price of the seed. Although some varieties of hybrid corn may be engineered to be disease resistant, grow taller or produce more ears, they all start out the same. However, most varieties of hybrid corn seed must be purchased every year as most are sterile.
Choose the appropriate variety of hybrid corn to plant in your area. Certain varieties are cultivated for their insect tolerance, early maturity or disease and drought resistance. If you are unsure of what hybrid variety to choose, discuss your needs and limitations with a producer.
Plant early. Most varieties of hybrid corn are bred to be high producers. These varieties produce the most when they are planted early: between the last week of April and the middle of May. This reduces the risk that they will succumb to early fall frost. However, if you must plant later in the season, choose early-maturing, short-season hybrids.
Prepare the soil. Hand or roto till the soil to a depth of 6 inches. Break up any clumps of dirt that you find along the way and remove any rocks, roots or other debris. Then spread 1 inch of aged compost 1lb of complete organic fertilizer per 20 feet of row you intend to plant. Turn the soil again to a depth of 6 inches. Then rake the soil smooth.
Water the soil well, so that it is moist to a depth of a few inches. Then allow the soil to warm up again over the next few hours or until the next day. Use a soil thermometer to measure the soil's temperature at a depth of 3 or so inches. Do not plant until the temperature is at least 60 degrees Fahrenheit.
Create planting rows. Create shallow furrows that are a few inches deep to mark your rows. Each row should be at least 3 feet apart.
Plant each kernel of corn 2 inches deep and 3 inches apart. Do not water again, this will cool the soil.
