The hybrid belongs to the FAO 500–600 maturity group. In non-irrigated conditions, the yield is up to 12 000 kg/ha, and under irrigation — up to 14 000 kg/ha. The plant is characterized by stress tolerance.

The grain of the hybrid responds well to nitrogen fertilizer application, which contributes to the optimization of the chemical composition, including the content of protein, starch, ash, and dry matter.
