The productivity of Italian ryegrass is assessed by the yield of green mass or dry matter over several cuts. This indicator is characterized by high potential, reaching 500–600 ц/ha or more per season under intensive management.

crop Italian ryegrass,
where this is mentioned in the description.
Accounting for the yield of Italian ryegrass is conducted by weighing the mowed mass from sample plots followed by extrapolation per hectare. For an objective assessment of forage value, productivity is measured as the sum of 3–5 cuts performed during one growing season, taking into account the dynamics of vegetative mass accumulation.
The yield of this crop shows high responsiveness to nitrogen nutrition, where doses of approximately 180 kg a.i./ha can significantly increase forage mass yield. Final productivity varies substantially depending on the cultivar type, as diploid and tetraploid forms differ in the intensity of vegetative mass development and the rate of regrowth after mowing.
