Alfalfa is the most productive and widely adapted forage species. In Montana, current (2000) alfalfa acreage is 1.2 million acres, with a gross value of $231 million. Acreage is about 54% irrigated and 46% dryland. Alfalfa harvested acreage and production have dropped significantly since 1999, due to prevailing droughty conditions throughout Montana which limited irrigation water supplies, dryland productivity, and a shift to alternate annual forages. Most alfalfa hay in Montana is fed on-site. Since winter feed is the largest expense for ranch operations, efficient and optimum hay production is crucial for ranch profitability. Forage yield and quality vary widely across Montana environments and operations. The Montana Agricultural Experiment Station (MAES) conducts variety performance trials at its research centers in major dryland and irrigated areas. Many alfalfa varieties are available to US producers, and these performance trials are designed to assist Montana producers in their variety selection. New alfalfa varieties are tested for forage yield for three production years at both irrigated and dryland sites. All Montana trials are planted as randomized complete block experiments, with four replications. The trials are “uniform” – all varieties are tested at all locations. Trials receive adequate fertilization and weed control for optimum production. This publication provides yield performance at six Montana locations. Detailed summaries for the 2001 harvest year (trials seeded in 1998 and 2001) are shown in Tables 1 through 20. Tables 21 through 32 are historical summaries for alfalfa trials seeded since 1984. Producers should choose varieties in Montana based on winterhardiness, yield potential, pest resistance and availability. For irrigated production in short (3 to 5 years) rotations, there are many high-yielding varieties available. For long-term stands on dryland, several varieties have forage yields superior to Ladak 65. We are unable to maintain our research stands for 10+ years to evaluate long-term survival and production. Use the performance data for the research site most similar to your ranch or farm. Be sure to evaluate forage yields in the 3rd and 4th years – downward trends in yield may indicate winter injury. Additional variety descriptions for pest resistance and fall dormancy, as well as specific information about the Montana alfalfa trials are available from the authors.
