‘Alkar’ is a tall, very late maturing, stemmy, bunch-type wheatgrass with coarse, blue-green leaves. Seeds are large with good seedling vigor. It is very tolerant to wet alkaline conditions in semi-arid regions of the West. It is fairly palatable and highly productive on sub-irrigated and irrigated saline and alkali land. Alkar is primarily used for pasture, but can be used for hay or silage.

Planting Depth: .5” on medium to fine textured soils, 1” on coarse textured soils

Planting Rates: 10-15 lbs per acre.

Planting Dates: Mar-Apr, Aug-Sep

Tall wheatgrass should be planted with a drill into a firm, weed-free seed bed. It is usually seeded in pure stands or in mixtures with grasses also having moderate palatability. If seeded in a mix, adjust seeding rate accordingly. Under dryland conditions, heavy to medium textured soils should be seeded in the very early spring, and medium to light textured soils should be seeded in the late fall. Irrigated land should be seeded in spring or late summer. Late summer seedings are not recommended unless irrigation is available. Tall wheatgrass has excellent seedling vigor but is slow to establish. To ensure plants become well established, haying and grazing should be deferred for at least two growing seasons on dryland one growing season on irrigated land.


Alkar is adapted to a wide range of soil types and climates. It is often recommended for 12”-14” and higher precipitation zones or sites with high water tables at 4,000’-6,000’ elevation zones. It is well adapted to wet, alkaline soils such as greasewood and saltgrass sites where the water table is from a few inches to several feet below ground surface. It is less drought tolerant than crested wheatgrass, however it is adapted to sagebrush, mountain brush and juniper sites. Basin wildrye is a good indicator of where tall wheatgrass will be successful. Because of its late maturing characteristic, tall wheatgrass provides a long grazing period. Our results indicate it performs well in New Mexico and Kansas, but not in Montana, and results are variable in Oklahoma and Texas.


Tall wheatgrass responds well to irrigation and fertilization. N should be applied in fall or early spring based on soil test recommendations. To maintain stands, 6 inches of stubble should be left at the end of the growing season. Grazing the following season should be delayed until there is at least 8 inches of new growth. Alkar is most palatable during the early spring months and should be managed during this time. If the grass is not managed, old coarse growth may inhibit grazing the following year. Alkar must be grazed heavily to maintain plants in the vegetative state. However it does not tolerate continuous close grazing and a rest period is required between grazing events. Tall wheatgrass is long lived and spreads slowly. It is not considered a "weedy" or invasive species, but can spread into adjoining vegetative communities under favorable climatic and environmental conditions. 


Grass family (Poaceae). Tall wheatgrass is a tall, long lived perennial bunchgrass reaching 3’-10’ tall. Leaves are green or glaucous bluish with blades flat to curling, 0.08”-0.31” wide. The blades are often covered with short, stiff hairs making them scratchy to the touch.
