Dry Matter — Smooth Brome

Bromus inermis Leyss.

The mass of smooth brome plant material after water removal, used as a primary indicator of forage productivity and quality. It reflects nutrient concentration, the dynamics of which are strictly linked to the plant's growth stages.

In the reference 5 varieties crop Smooth brome, where this is mentioned in the description.

For smooth brome, yield is traditionally measured in centners or tons of dry matter per hectare, which allows for an objective comparison of the effectiveness of varieties and agrotechnical practices. Furthermore, dry matter serves as a basis for calculating the water use efficiency coefficient, which determines the volume of water required to produce a unit of biomass.

The nutrient content in smooth brome is subject to significant changes across growth stages. As the plant transitions from tillering to seed maturation, the proportion of dry matter in the biomass increases, but its quality declines: crude protein concentration drops from 27–28% to 7–8%, while fiber content rises from 27% to 42% or more.

Total dry matter yield in high-yielding smooth brome varieties can range from 50 to 135 centners/ha depending on growing conditions. Breeding efforts are focused on increasing this metric by optimizing plant architecture and leafiness, while the selection of the optimal harvest timing remains a key factor in balancing forage quantity and nutritional value.
