The ability of the crop to produce a significant volume of vegetative mass over a short growing period of 65–80 days. This indicator directly depends on nitrogen nutrition, moisture availability, and adherence to mowing phases to prevent a decline in aftermath quality.

crop Westerwolds Ryegrass,
where this is mentioned in the description.
The productivity of Westerwold ryegrass is estimated by its green mass yield, which ranges from 200–400 c/ha, and dry matter yield with a potential of up to 14–20 t/ha per season. In seed production, yield varies from 1.5 to 16 c/ha depending on agrotechnical conditions and climate.
High productivity is ensured by intensive tillering and allows for 3–4 cuts per season. Realizing this yield potential is strictly limited by nitrogen availability, requiring up to 180 kg a.i./ha, and moisture availability due to the shallow root system of the plant.
A critical factor for maintaining productivity is strict adherence to harvest schedules. Delaying mowing until more than half of the plants have formed inflorescences leads to a sharp decrease in nutritional value and slows down the regrowth rate of the aftermath after cutting.
