Pioneer Experts Have Tips for Establishing a Good Alfalfa Stand This Fall

One of the biggest alfalfa planting mistakes is planting too deep. Experts recommend planting in a firm seedbed to ensure correct depth.

Good seedbed preparation and late summer management are among the biggest factors that determine a successful, high-yielding alfalfa crop, say experts at Pioneer Hi-Bred, a DuPont business.

Alfalfa is a long-term investment for growers and, to maximize productivity, there are several steps to take before seeding in the fall to ensure good stand establishment the next spring.

"Once growers have alfalfa established, it is a great crop for a long-term rotation," says Dan Berning, Pioneer technology services manager. "But growers want to get it right. They won't have another chance on that field for a while."

To thrive, alfalfa seeds require good seed-to-soil contact. Because of their size, the seeds should not be planted very deep, since that may cause emergence challenges. To ensure holding moisture, growers should plant in firm soil.

"In the ideal seedbed, a footprint doesn't leave more than a half-inch depression," Berning says. "This is firmer than soil needed for planting larger seed crops, but growers need to recognize alfalfa seed is very small."

"A firm seedbed helps prevent the biggest mistake in alfalfa planting - planting too deep," says Gary Brinkman, Pioneer area agronomist.

Selecting the right planting time also is important to good alfalfa establishment. Optimum planting times depend greatly on the region.

"It is important to plant early enough to establish growth before fall dormancy," Berning says. "A rule of thumb is to plant no later than one month before the expected fall freeze, unless that won't provide adequate growth in your region."

Typically, growers should not harvest alfalfa before winter, but rather manage it. If growers cut their alfalfa crop in the fall, it depletes the root reserves of nutrients.

"When the stands get cut too late in the fall, typically growers will see more winter-kill resulting in a thinner spring stand," Brinkman says. "If growers decide to cut, they should leave at least 6 to 8 inches of stubble."

Before planting and during the beginning stages of alfalfa growth, growers should scout for potential insect infestations. For more information on Pioneer brand alfalfa varieties, contact your local Pioneer sales professional or visit www.pioneer.com/forages.
