Advantages of Twin-Row Corn Production

Twin-row corn has attracted interest as a way to potentially increase yields without some of the difficulty and costs of switching from 30-inch rows to narrow rows. In a twin row configuration, corn is planted in paired rows, usually 7 or 8 inches apart, on 30-inch centers. This allows uniform plant spacing similar to narrow-row corn without requiring new machinery…Read more

Soybean Cyst Nematodes

Soybean cyst nematodes are a perennial threat throughout the United States. One of the most serious errors growers can make is planting a susceptible variety in fields with previous infestations. That mistake can result in a 50 percent or greater yield loss. What complicates variety selection even further is that SCN exists as different “types” (formerly known as races). Different types of SCN endure differently based on the variety of soybean host…Read more

Spider mites are tiny arachnids closely related to ticks and spiders. They are most problematic for corn growers in the High Plains and western United States. In high numbers, they can significantly damage corn.
