‘Manifest’ intermediate wheatgrass (Thinopyrum intermedium (Host) Barkw. & D.R. Dewey subsp. intermedium) was a cultivar released in 2007. It is a cool-season perennial sod forming grass used most commonly in the Northern Great Plains. Manifest is selected for its forage yield, seed yield, spring vigor and resistance to leaf spot disease. It has consistent high forage yield over a wide geographical area. Finally, it remains persistent even when grazed.

Manifest Intermediate Wheatgrass Uses:

Manifest is recommended in grass and grass-legume mixtures for hay and grazing. When compared to Reliant, Manska and Oahe, Manifest exhibited higher shoot replacement ratios. This should allow Manifest to withstand grazing and provide increased stand longevity compared to other varieties. Manifest provides upright tall nesting cover and escape cover for many ground nesting birds and small and large mammals. This variety also has potential as a perennial crop for cellulosic biomass in northern areas adapted to cool season grass production.

Management:

Manifest intermediate wheatgrass is palatable to all classes of livestock and wildlife. It provides excellent spring, early summer, and fall pasture. It makes good quality hay when harvest in the boot stage. Often times Manifest is mixed with alfalfa to enhance productivity and to prevent alfalfa from lodging.

Eight inches of new growth should be attained in the spring before grazing is allowed on established stands. Six inches of regrowth before killing frost should be maintained following grazing or haying.

Adaptation:

Manifest intermediate wheatgrass was developed for use in the Northern Great Plains. It is projected to perform well in the Central Great Plains, Upper Midwest and parts of the Intermountain West where annual precipitation averages more than 14 inches.

This species is utilized best in spring, early summer and fall. Manifest appears to be adapted to a wide range of coarse to fine textured soils. It is similar to other intermediate wheatgrass varieties listed as moderately tolerant to saline soils.

Establishment:

Manifest is easily established when seeded into a well packed weed-free seedbed. The optimum seeding depth should place the seed not more than 1 inch from the soil surface. Establishment can be improved by using moisture conserving seedbed preparation practices and seeding methods to maximize the available soil moisture on the site. If weed competition becomes a problem, herbicides can be applied. The seeding rate of Manifest is similar to other intermediate wheatgrass varieties. A seeding rate of 8.5 pounds PLS/acre (17 seeds/ft2 ) is recommended in western North Dakota. The recommended seeding rate is generally higher in eastern North Dakota where a seeding rate of 10 pounds PLS/acre (20 seeds/ft2 ) is recommended.
