Crested wheatgrass is an early maturing, long-lived, drought-tolerant bunchgrass with excellent seedling vigor and ease of establishment. It is used primarily for hay and early spring pasture.
The fairway types are shorter, leafier and less likely to form large clumps with age. The standard types are generally taller and thicker-stemmed, and produce more forage.
The variety Fairway frequently is used in dryland lawns and pastureland. Ephraim has lower forage yields but was selected for its slowly developing sod-forming characteristic, which is useful as a low-maintenance ground cover.
RoadCrest has a short stature and finer leaves and is moderately rhizomatous. AC Goliath, HyCrest and HyCrest II are high-yielding varieties of hybrid crested wheatgrass obtained by crossing standard and fairway types.
Green (RS hybrid) (Elymus hoffmannii)

AC Saltlander | 2004 |
NewHy | 1991 |
It is classified as a hybrid between bluebunch wheatgrass and quackgrass. Green wheatgrass has good forage quality and remains succulent for livestock for longer periods in the growing season than most other wheatgrasses. It can be grazed in the fall.
It stockpiles well and tends to maintain a high level of productivity. Its moderate vegetative spread is much less than with quackgrass. Salinity tolerance is high and similar to that of tall wheatgrass. Seed quality and germination generally are lower than in other wheatgrass species.
NewHy has established readily and performed well in trials in North Dakota. AC Saltlander was specifically selected to tolerate root-zone salinity while providing a good-quality hay option.

*North Dakota release
1Limited North Dakota production trials indicate Rush intermediate wheatgrass is less productive than other approved intermediate varieties; therefore, Rush will be used for conservation cover plantings only. In addition, Rush is a protected plant variety (PPV) and should be available only as commercial certified seed as designated by a blue seed tag.
Intermediate wheatgrass is a vigorous, fast-growing, sod-forming grass. It produces an abundance of basal and stem leaves.
Varieties differ in the amount of pubescence on the seed head and leaves. The pubescent varieties are reported to be more drought-tolerant and form a sod more rapidly than intermediate varieties.
This species has produced more biomass than most other cool-season species in performance trials in North Dakota. Newer releases are more productive with higher-quality forage.
Both types of intermediate wheatgrass often are included in seed mixtures for hay and pasture due to their ease of establishment and fast growth. To maintain productivity, do not closely graze in the spring and do not graze past Aug. 1. Intermediate wheatgrass often is used in seed mixtures for wildlife habitat.
Reliant is more of a bunch type, developed to be less competitive with alfalfa in hay land planting. Manska, reselected from Mandan 759, has shown significantly higher forage quality and improved animal daily gain in grazing tests in Nebraska. Manifest is the newest release and has greater persistence under grazing and excellent hay yields.

Stabilizer | 2011 |
Vavilov II | 2008 |
Vavilov | 1994 |
P-27 | 1953 |
Similar to crested wheatgrass in appearance, Siberian wheatgrass has awnless seed heads more numerous than crested. It is drought resistant, long lived and well adapted to light, droughty soils. It establishes readily and is known to withstand very heavy grazing pressure after establishment.
Siberian wheatgrass generally is not recommended in areas that receive more than 14 inches of annual precipitation. Vavilov II expands the genetic base of the Vavilov, with increased seedling establishment and stand persistence during drought, and well as being adapted to a wide range of ecological sites receiving as little as 7 to 8 inches of precipitation.

Platte | 1972 |
Orbit | 1966 |
Jose | 1965 |
Alkar | 1951 |
Tall wheatgrass is a tall, coarse, late-maturing bunchgrass with large seed. It is a special-purpose grass used primarily to revegetate saline-alkali soils and provide wildlife cover.
The plant normally becomes coarse and unpalatable to livestock as it matures. Palatability of hay is fair to good if cut prior to or just after heading. A 6-inch stubble height should be left.
Tall wheatgrass is used in narrow, uniformly spaced barriers for soil erosion control and to manage snow for moisture conservation on cropland. It often is seeded in a mixture with intermediate wheatgrass, alfalfa and sweetclover for wildlife habitat.
Alkar is the most commonly used variety. Jose is finer-leaved and rated higher in forage quality.
