Blackrock

Blackrock — a mid-season three-line dent-type hybrid with high yield potential. Plants of this hybrid are tall, with medium ear height placement and medium tassel coverage. The hybrid has good initial growth energy and medium cold tolerance, ensuring its adaptability to various climatic conditions.

One of the key features of Blackrock is its excellent resistance to root and stalk lodging, which helps maintain yield and reduce losses under adverse weather conditions. The hybrid is suitable for minimal soil tillage and can be successfully grown in monoculture, simplifying agronomic practices and increasing production economic efficiency.

Recommended planting dates for Blackrock depend on soil temperature: optimal planting is at 10–12 °C, and optimal-late planting is at 12–14 °C. Recommended planting density at harvest varies by region: 70–80 thousand plants per hectare in the Polissya region, 60–70 thousand in the Forest-Steppe, and 50–60 thousand in the Steppe. These parameters allow maximum expression of the hybrid's potential and enable high-quality sugar corn harvests.
