Intermediate Wheatgrass

(Agropyron intermedium)


Intermediate Wheatgrass is a native of central Europe and Asia. It is a long-lived, cool-season plant that grows to a height of 7.5 to 10 cm (3 to 4 in.) under good soil and moisture conditions. All strains planted in New Mexico require a minimum annual precipitation of 39 cm (15. in) with a high percentage of the effective moisture falling in late winter and early spring.  It requires more moisture than Crested Wheatgrass, but the season of use is extended. It has been used in irrigated pastures, and it is particularly useful where water supplies may be inadequate during late summer.

Seed is easily planted through a drill and should be seeded no deeper than 2.5 cm (1 in.). Planting dates should be the two-month period with most favorable moisture (spring or fall).

The New Mexico Agricultural Experiment Station and the USDA Soil Conservation Service cooperatively released Amur in 1952. The source of the original seed was from Manchuria, China.

Amur's foliage is blue-green. It is superior to other strains of intermediate in seedling vigor and high seed production over a greater number of years. It is good dryland pasture grass and should be used in preference to other strains in Colorado and New Mexico. Sites where it is well adapted would be associated with the Oak Brush and the higher limits of the Big Sagebrush zones.



Greenar is a dark green, moderately rapid, sod forming cultivar. It is widely adapted but most commonly used in the northern parts of the mountain and intermountain regions.



Oahe is a tall, coarse, blue-green variety that is a rapid sod-former. It has been used most extensively in the Dakotas, eastern Wyoming and eastern Montana.
