Productivity of rescue grass

Bromus catharticus Vahl

The productivity of the crop is defined as the dry matter yield over a series of successive harvests, depending on stand density, plant height, and leafiness.

In the reference 6 varieties crop Rescue grass, where this is mentioned in the description.

The primary indicator of productivity is the dry matter yield in tons per hectare, measured under multi-cut systems that include from four to seven harvests per growing season. Depending on the climate and the level of nitrogen nutrition, dry matter yield ranges from 6.8 to 14 t/ha.

When assessing productivity, the size-density compensation mechanism is taken into account, where a decrease in shoot density is often compensated for by an increase in individual shoot weight. The crop exhibits a high regrowth rate during the winter-spring period, but it is sensitive to mowing frequency due to the high proportion of generative shoots in the yield structure.

There is an inverse relationship between quantitative biomass accumulation and forage quality indicators, such as protein content. To maintain stable productivity, it is important to select management regimes that promote the longevity of the stand during the first years of the plant's life.
