The hybrid belongs to the FAO 220 early-maturity group and is intended for use as specialized silage and feedstock for biogas production. The plants are characterized by tall height and high ear placement; the grain is of a dent or flint-dent type.
The variety possesses high drought tolerance, resistance to lodging and smut diseases, and demonstrates good moisture release. The hybrid is suitable for cultivation under minimum tillage and monoculture conditions.
The recommended plant density at harvest is 70–75 thousand plants per hectare under sufficient moisture and 65–70 thousand plants per hectare under drought conditions; for silage, it is recommended to increase density by 15–20%.
