where this is mentioned in the description.
The productivity of Italian ryegrass is assessed through indicators of green mass and dry matter yield, expressed in tonnes per hectare, as well as protein content and energy value. During breeding trials, yield is determined through multiple mowings throughout the growing season, which allows for the accounting of the sward's high regrowth rate.
Modern intensive varieties of Italian ryegrass are capable of providing yields of up to 10 tonnes of dry matter per hectare. Tetraploid forms of the crop are characterized by an increased potential for green mass formation, better leafiness, and a higher sugar content. Total productivity is significantly influenced by moisture availability and temperature conditions, while the timing and frequency of mowing serve as critical factors.
