Bothriochloa caucasica

Pasture and hay.

Advantages
More uniform growth rates over summer season, more tolerant of close grazing than native warm-season grasses. Multiple cuttings possible.

Disadvantages
Fluffy seed that is hard to handle, slow to establish. Can become a weed in crop fields. No cover value for wildlife. Quality and animal acceptance declines rapidly with maturity compared to big bluestem and indiangrass.

*Pure live seed, or PLS, is equal to the percent germination multiplied by percent purity, both expressed as decimals. For example, a big bluestem seedlot that is 70% pure seed and 50% germination would be 35% pure live seed.
