Abstract

Causes of crown and upper root rot, symptoms and management are discussed here.

Alfalfa (Medicago sativa L.) is the most important forage crop species in North America. It is widely adapted, energy efficient, and produces the most protein yield per acre. Alfalfa is well-suited to both dryland and irrigationd soils of Nebraska.

Many factors contribute to the decline in productivity of an alfalfa stand. Under favorable growing conditions and proper management, alfalfa stands in Nebraska can last over 10 years.
