Ladak II alfalfa is a top dryland performer. It is an excellent choice for inclusion in dryland pasture mix and is commonly used in grass mixes for improved pasture applications. Ladak II is specialized for use on rangeland and dryland pastures from the northern plains to the winterhardy intermountain areas of the west where rainfall is limited for extended periods of time. Performs very well in harsh soils and adverse conditions. It is drought tolerant and has an edge over Ranger in arid conditions.  It has a deep tap root. Demonstrates very good winter hardiness with a fall dormancy 3.

The original USDA public Ladak strain has long been a favorite of farmers and ranchers in the intermountain west for arid sites. Widely used at the Utah Great Basin Research Station in range seeding and by the BLM Boise Regional Seed Warehouse. The original strain was slow to recover between cuttings. Ladak II alfalfa is an improvement on the original strain, developed from plants selected out of a 27 year old stand in eastern Washington. Ladak II has the drought tolerance of Ladak with improved disease and nematode resistance for increased persistence and adaption to a wider range of soil conditions.

Our Certified Ladak II is an improvement on the original.
